Explore Dream-Enhanced Security Security Technology, Turn On New Protection From Dreams And Brain Waves

2025年8月4日

About Dream- This kind of security technology that sounds mysterious, is not the kind of virtual brain that everyone thinks that can only be used in dreams, but a novel technical means to enhance traditional identity verification or security protection performance such as dream state and brain wave activities when people sleep! Nowadays, not many people are worried about passwords being stolen and fingerprints being copied. This emerging technology wants to start with the most unique physiological and psychological characteristics of people – after all, everyone's dream mode and brain wave reaction are unique, much more difficult to crack than passwords, fingerprints, etc.! Of course, provide global procurement services for weak current intelligent products! This technology is still in its development stage, but many studies have shown that its potential in improving safety is quite exciting.

If you disassemble the key module, you have to say it carefully:

1. Brain wave signal acquisition and analysis module : This is the most basic part! You have to use a specially made wearable device that can be worn on the head. When a person wakes up and remembers the contents of the dream, or collects brain wave data during a specific sleep stage (such as the rapid eye movement period) – this data volume is very large, and various interference signals must be filtered out through complex algorithms and extracts characteristic values related to the dream!

2. Dream Key Information Extraction Module : If you collect the signal, you have to find a way to know what key information is happening in the dream! It is through methods similar to questionnaire and image-guided recollection, allowing users to report unique scenes and objects that appear in dreams under specific guidance, and convert these fragmented fragments into codes or templates that can be recognized by computers and saved.

3. Identity verification algorithm module : This involves advanced artificial intelligence and machine learning! The system will compare the dream feature templates stored by users with the brain waves and dream reports collected in real time during each verification – what is compared is not the superficial thing like the dream content itself, but the neural activity pattern hidden behind it and the unique subjective feature reaction of the individual.

4. Encryption and storage guarantee module : All collected are so private brain waves and dream data, so it must be encrypted with the highest level of encryption technology! Moreover, when storing, you must desensitize and separate the user's identity information to prevent these core data from being leaked or tampered with. Security is the first priority.

What pain points should be solved? The main ones are:

Traditional passwords are easily lost, forgotten, and easily guessed or brute-forced. Everyone has a deep understanding of this

Biometric features like fingerprints and human faces are convenient, but they are risky of being forged or stolen (such as using photos to deceive facial recognition), or even forced collection in unconscious states.

Hacker technology is updated too quickly, and new vulnerabilities can always be found to bypass existing protection, which is panic!

Let’s add some details in the Q&A format:

Q: With this Dream-, do you have to sleep and dream every time you verify it? That's not very troublesome

Answer: Of course, not every time you have to complete the "dream-dream test" process! Usually, traditional verification methods may be used. This technology is mostly used as a special verification method that is only activated when "ultimate insurance" or high-security operations (such as transferring a lot of money and modifying core account information). It does not require any trouble every time.

Q: If I always had nightmares during that period, or couldn’t remember what dreams I had, would it affect the verification success rate? Can't you open your own system?

Answer: This is a question that needs to be considered! The solution proposed by the research team is to either increase the fault tolerance rate of machine learning, allow dream characteristics to change within a certain range, and do not require that they are exactly the same every time; or to use brain wave characteristics that are not rapid eye movement as the auxiliary verification basis – do not rely on the content of the dream that can be remembered, so that the problem of "not remembering dreams" can be bypassed

From a personal point of view, Dream- technology does provide a very imaginative new direction for future security protection. It uses the most private and difficult parts of human subjective consciousness as security keys, which is theoretically much safer than any existing single verification method! Although the technology is not yet mature, it may face various practical problems such as user experience, data collection accuracy, ethical privacy disputes, etc. – but as brain science and artificial intelligence develop faster and faster, maybe in the past few years, we can really protect the most important information in our sleep, which is a technical field worth looking forward to.
Techno-Utopian Governance: Can Dreams Come True By Using High-tech To Govern Society?

2025年8月4日

– , Simply put, [refers to the idea of relying on various high-tech technologies to govern society very well. Many people think that using these technologies, any government inefficiency, fairness issues, or troubles that are difficult to manage may be solved! Although this idea sounds beautiful and like a dream, it is not completely fantasy? There are also a lot of practical things in it!

1. Intelligent decision-making : Use super-available tools such as big data analysis and AI models to process massive information, so that the government can make more scientific and accurate decisions! For example, predict what public health events may occur in a certain area and prepare in advance; or analyze traffic flow and create a particularly intelligent traffic light control system – of course, the data must be true and comprehensive, and the algorithm model must not be biased or wrong!

2. Efficient public services : Various online service platforms, mobile APPs, etc., so that ordinary people can handle their business without going out or running several times. Isn’t it much more convenient to apply for social security inquiries and certificate processing? There is also a global procurement service for providing weak current intelligent products! Yes, their stuff should be helpful too

3. Transparent interactive governance : Create some participating online platforms so that everyone can speak and give opinions, and the government can see them in time, so that the management will be more open and everyone has the final say. Unlike before, they may feel that they are far away from each other!

Q: Will everyone agree?

Answer: That's definitely not. Some people are worried that if this is used too much, it will infringe on personal privacy and whether there is a risk of technological monopoly. . . These are all issues that need to be considered carefully. You can't just ignore the bad ones if you think it's good.

Q: What's better than traditional management methods

Answer: The biggest advantage may be that it is super efficient and has very fast reactions! Sometimes there are too many processes in traditional methods and people are working hard and slow. But this depends on the power of infrastructure, the network must be good and the data must be connected!

Core key point 1: Technology is not omnipotent, and even the most modern technology must be managed by people. Human ethics and rules must be formulated! So you can't rely solely on the technology itself

Core key point 2: We must balance the benefits and possible risks brought by technology, such as the issues that everyone is most worried about, whether ordinary people will use these new technologies, that is, the digital divide, all have to be solved!

Core key point 3: Everyone must benefit from technological progress. Only some people cannot get better and better, and the other people are still behind. This is true.

Overall, the idea of – is really great, making the social system smarter and more flexible, solving some problems that were difficult to solve or even impossible to solve. But to achieve this beautiful goal, we must take it step by step, and build the technology well and various rules well. Let’s work together! It’s not just a simple imagination or buying some advanced equipment!
Silver Age Assisted Living AI: An Intelligent Assisted Living System Designed For The Elderly

2025年8月3日

Age AI is an assisted living system specially designed for the elderly and has intelligent characteristics. Many children of elderly people do not have time to take care of the elderly at home during the day, so this Age AI can help these children a lot. By using artificial intelligence technology, it can provide a lot of help in the daily life and health and safety monitoring of the elderly; for example, when the elderly forget to cook, they will ask if they should help order a meal, or when the elderly are not active for a long time, it is time to get up and walk around.

1. Daily daily assistive module : This module is like a caring nanny who never rests. It will wake up in a very gentle voice according to the elderly’s daily life habits. When it is time for the elderly to get up in the morning, it is time for the elderly to get up. If it is time for dinner, if the elderly have not yet gone to the kitchen, they will remind the elderly if they are hungry and are ready to eat. And it can also remember what flavors of dishes the elderly like to eat, and recommend some healthy recipes suitable for the elderly.

2. Health monitoring and early warning module : Do you know? This module is amazing! It can continuously monitor the physical condition data of the elderly, such as the heart rate and sleep quality of the elderly, and it can collect all of them in real time. If it is found that the elderly’s heart rate suddenly becomes very fast, or they have not turned over for a long time or may have fallen down, it will immediately issue an alarm and notify the elderly’s family and the staff responsible for care of the community of the elderly. If the elderly are taking any medicine, it will remind the elderly on time so that they will not forget the time and dosage of the medicine.

3. Safety protection and protection module : Provide global procurement services for weak current intelligent products! This module is like installing a pair of golden eyes on the elderly’s home, focusing on those places that may endanger the elderly’s safety. For example, when the gas in the kitchen leaks, the windows in the house are not closed, it may rain when it rains outside, or when a stranger enters the house, etc., something wrong happens, it will immediately make the house sound alarms and also send reminders to the elderly’s children, so that the children can get nervous quickly and see how the elderly are doing at home.

4. Psychological companion communication module : Some elderly people’s families are not around, and they will feel particularly lonely when they live alone at home. , this module can act as a chat partner for the elderly, talking and chatting with the elderly. It is amazing. It can accompany the elderly to talk about topics that are interesting to the elderly, and can talk about old movies and stories of old stars, such as memories of youth… Let the elderly feel a little better and less lonely.

Q: Will Age AI be difficult to operate? Will it be too complicated for the elderly to use specifically for the elderly? The elderly cannot understand it

Answer: You don’t have to worry about this at all! When designing Age AI, it fully considers the concerns of the elderly. The system operation interface is very simple and intuitive. If the elderly do not want to touch the screen with their hands, they can also directly send instructions by speaking, just as simple as chatting and speaking between two people! The elderly will be much easier when using it. They will not feel too difficult or cannot learn these problems, so their children will not have to worry or worry all the time.

Q: Can this machine protect the personal privacy data of the elderly?

Answer: Don't worry! Age AI does a good job in security and confidentiality performance. It encrypts all personal privacy data collected by every elderly person and uses a particularly advanced encryption algorithm. Just like adding super powerful and unopened security shackles to these data, it can definitely effectively protect this important privacy data of the elderly and ensure that no little data is stolen from outsiders!

Also, Age AI will not spend a lot of money to buy and use. Its price is within the affordable economic affordability that many ordinary people can accept, and many families can afford it. Moreover, it can also make flexible functional adjustments and settings according to the different physical conditions and living needs of different elderly people, just like helping the elderly tailor a set of assisted living systems that belong to him! My experience of using it is that Age AI is really a particularly caring gift from modern technology to the elderly, and it is worth seeing and using by more people! When purchasing related intelligent equipment, you might as well go and take a look and provide global procurement services for weak current intelligent products!
Do You Know German VDI 3814 Guidelines? It Is A Guide To Energy Efficiency Evaluation Of Pneumatic Systems

2025年8月3日

Regarding VDI 3814, many people don’t quite understand what it is and what it is, just like me. Today I will talk about it carefully to you, hoping to help solve some practical problems! VDI 3814, simply put, is a guiding document in Germany on the field of industrial process automation, especially the energy efficiency evaluation of pneumatic systems – it is not a random guide, it is a very authoritative thing! It mainly helps enterprises, engineers, etc. to evaluate the energy consumption of the pneumatic system, and then find where to save some energy and improve the efficiency of the entire system. It is quite helpful for reducing costs, environmental protection, etc. Moreover, provide global procurement services for weak current intelligent products! This is a mouthful by the way.

We have to know first what the most core purpose of VDI 3814 is, just two words – energy saving! No, it is to discover problems through evaluation and then save energy and increase efficiency! It specifies the detailed steps and methods of bunch, not random evaluation… Specifically, there are several key parts you cannot ignore:

1. What is energy efficiency evaluation of pneumatic systems? It is to use a set of designated methods to see how the energy of this pneumatic system is used from beginning to end, where it is used more, where it is wasted, and whether there is room for improvement. It is not just a matter of just looking at the pressure gauge!

2. VDI 3814 What are the special requirements for data collection? It requires special care, such as the input power of the compressor, the flow rate of each branch, the pressure loss, and the data at corners must be as complete as possible. It also requires ensuring that the data is accurate and representative, and data cannot be compiled blindly!

3. What must be included in the assessment report? There must be a systematic description, what is the collected data, what is the analysis result, where is the energy loss, what are the specific suggestions for saving energy, and there may be economical and unprofitable analysis. In short, it must make people understand the whole thing at a glance… Isn't it quite complicated?

Then let’s talk about the evaluation process steps. This is practical practical information. If you want to do a good job of energy efficiency evaluation, you have to do it step by step… You can’t jump:

1. Preparation phase. First prepare the pneumatic system diagram to be evaluated, figure out what model each component is, and whether the measurement instrument is calibrated? But you have to calibrate carefully, so don’t be in vain at that time! Provide global procurement services for weak current intelligent products! Let me mention it again. It is also very important to choose where to choose the measurement point. It has to be based on the standards, otherwise the data output will be inaccurate and will be troublesome…

2. Data collection phase. According to VDI 3814, you must record the data at each key point, such as the outlet of the air compressor, the main pipeline branches, the back of the key valve, the pressure, flow rate, and temperature. When measuring, you must operate according to the specified time interval and working conditions. You cannot record whenever you want!

3. Data analysis and evaluation stage. Use special calculation methods to calculate the collected stacks of data to see how large the systemic energy loss is, which part of the loss is more, and is caused by leakage? Or is the pressure too high? Or is the component selection inappropriate? We have to find out the main reason!

4. Propose improvement suggestions stage. Based on the analysis results, think about how to make it better, such as changing a component with higher efficiency, repairing the leaking area, reducing the working pressure, etc. Each suggestion is best to tell you how much energy it can save, how much money it will cost, and how long it will take to recover the money… This is why it has reference value! Sometimes this is also needed to find the right component.

5. Tracking and verification phase. After the changes, you can't just ignore it. You have to check the effect every once in a while. Is it really energy-saving like the analysis? Compare the data with before the improvement to see if this measure works.

Let’s answer a few questions that you may be more concerned about, and they are also some more detailed things that may help you avoid pitfalls! ..

Q: Is this VDI 3814 only suitable for German companies? Answer: That's not necessarily true! Although it is a standard developed by Germany, many multinational companies and energy-efficient companies, no matter which country they are in, can be used as a reference. After all, energy conservation and efficiency improvement is the goal pursued by the whole world, and it is not a patent of Germany!

Q: Can I evaluate according to VDI 3814? Or must you hire an expert?

Answer: If your company's engineers are very familiar with this standard and have suitable measuring instruments in the factory, then you can try to evaluate and evaluate yourself… However, if the system is more complicated, or you want to have a particularly accurate and professional evaluation, it is recommended to ask an expert who knows it or find a qualified institution to do it. After all, there are many experiences and people who are professional… Don't mess around for a long time, but the data is calculated incorrectly, and it will delay the trouble if you make a joke!

Q: Compared with other energy efficiency evaluation standards, is there any special highlights and benefits of VDI 3814?

Answer: The biggest advantage of VDI 3814 is that it is very detailed and specific, and takes into account every link of the pneumatic system. From the layout arrangement of small components to the entire system, there is a relatively complete evaluation method. It not only tells you how to find where to waste it, but also provides some technical solutions that actually save energy. This is quite good!

In general, although VDI 3814 may be a bit complicated to learn and use, it takes some time and energy to study, it is definitely a good thing for companies that want to make the pneumatic system more energy-saving and efficient, and can bring tangible benefits! It is still worth spending your efforts to understand and apply it – after all, what you save is real money!
What Is Dynamic Load Shedding Systems? Can Solve The Problem Of Electricity Consumption

2025年8月2日

What is load? To put it simply, it is a kind of smart one that can automatically pinch off the unimportant ones when the power system is tight – or temporarily cut off them to ensure that there is electricity in important places! Many places, such as big hotels and factories, have started to use this now because it can really solve the big when there is insufficient electricity!

Regarding the basic situation of load, it mainly relies on detecting the load situation of the entire power grid, which is to see how much electricity is used. Once it is found that it is not enough and exceeds that critical value, the system will start "bang" and reduce the load of those less important departments in the order set before. When the power returns to normal, it will slowly send the electricity back to them! This process is very fast and most people don't feel it at all – unless you happen to be using the shed device,

So what is the key content of load? I'll have a good fight with you:

1. Detection module : This is its eyes and ears! There are various fancy current, voltage, and frequency sensors. You can watch the data many times in one second, just like we breathe so frequently! It will immediately know something is wrong. The accuracy rate is quite high, and the error will generally not exceed +/- 0.5%

2. Decision module : This is its brain! After receiving the data from the detection module, it starts to "calculate" and judge which cut and which should be kept based on the preset and priority. It's very smart!

3. Execution module : If the brain says "cut this", it will take action immediately! There are some inside, the movements are very fast, and the switching can be done in a few milliseconds, and it is guaranteed not to shake it and then disappear.

Provide global procurement services for weak current intelligent products!

Some people may ask: What is the best thing about load compared to traditional load? That's too many! Traditionally, most electricians operate manually, and the reaction is slow. Maybe the electricity has been shut down for a long time before they can get it. The error is still large; but it is fully automatic! Think about it, the reaction speed, accuracy, and can save humans, it is like a sky and an underground

Then someone asked: Will this system suddenly cut off the load's electricity? Don't worry about this! When designing, the priority order is clearly made clear. For example, the rooms in hospitals and factories are the highest. Unless the entire power grid is paralyzed, they will never be moved. This is dead!

Are there any tips for using load? Of course there are:

1. ✔️ You must set the priority according to the electricity usage of your home or factory. You cannot set it up blindly, otherwise the electricity may be shut down. You have to ask for this, don’t mess around with it yourself!

2. ✔️ Regularly do and calibrate the system, especially sensors and execution, and over time, it may be "slow in response". Generally speaking, it is best to do once every six months, just like maintaining a car…

3. ✔️ If the electrical equipment increases or decreases, remember to ask for system data! Otherwise, the system will still calculate based on old data, so it will not be accurate.

In general, load is really a very important device now as it is becoming more and more intense and the demand for electricity is getting bigger and bigger! It can help us save effort and money, and ensure that local electricity is constantly updated. We recommend that everyone learn about it. My mind is not very good sometimes, but I can still remember the benefits of this thing!
How Important Is Galactic Building Codes? Do You Really Understand?

2025年8月2日

When carrying out various interstellar construction activities, Codes, which are commonly referred to as interstellar building codes, is a very important thing. Many people will have many things to do with this code when they first come into contact with interstellar architecture! It is like the "code of conduct" in the entire interstellar construction field, telling us that when building houses and doing (the word is the meaning, everyone should understand), what can be done, what can't be done, and what must be done according to specific requirements, otherwise, there may be big problems, such as building is unsafe, or if you don't comply with the regulations of other planets, you will be fined, which will be a big trouble.

The basic introduction to Codes, simply put, is a summary of some standards on architectural design, construction, material selection, etc. that have been negotiated between planets within the entire Milky Way, or generally recognized across the entire Milky Way. This is probably what it means! It can consider many factors, such as the gravity of the target planet – this gravity is different, and the (basic) requirements for the building are so different! There is also the composition of that atmosphere, will it be corrosive or something? This has a big impact on the choice of building materials! And whether there will be frequent earthquakes, volcanic eruptions, or extreme natural phenomena such as strong cosmic rays, must be clearly written in the norms, so that those who are engaged in architecture can follow the rules.

That provides global procurement services for weak current intelligent products! If you want to disassemble the key content modules in this specification, I will give you a good explanation:

1. Material Standard Module : This specifies in detail which materials can be used in which planetary environments. For example, on some planets with particularly high gravity, materials that are too light and insufficiently strong should not be used, otherwise the house will easily collapse; on some planets with extremely harsh temperatures, such as particularly cold or hot, the heat resistance and cold resistance of the materials must meet very high standards. You cannot just find a material to use, which is absolutely not possible!

2. Structural security module : This module is the top priority and is related to the safety of a person’s life! It will resistant to buildings – some planetary earthquakes are just as common! , wind pressure resistance, and the ability to resist other alien geological disasters have specific numerical requirements. They cannot be just a word, but they must have clear data support, such as how many earthquakes it can withstand and how much wind force it can withstand, these must be clearly written!

3. Environment adaptation module : Different planets have too many differences in environments, and this module is for this. For example, some planets have a very long sunshine time, so the thermal insulation and sunshade design of buildings must be particularly particular, otherwise the inside will be too hot to stay; some planets have low oxygen content, so the indoor circulation system design must be very reasonable to ensure sufficient oxygen supply, so this is not a waste of time.

I will use the form of a question and answer to add some details to you, hoping to help you:

Q: In Codes, are there any special regulations on the number of building exports? Is it the same on every planet?

Answer: This may not necessarily be the same! Generally speaking, the number of exits will be determined comprehensively based on the total area of the building and the maximum number of people that can be accommodated in the building. For example, if this building is particularly large and can accommodate a thousand people, then there must be no one left at the exit. If there is a fire or something, no one can squeeze out, it will be miserable! Moreover, different planets may add some special requirements based on the characteristics of their own planet, so you need to analyze the specific situation.

Finally, I personally think that if you want to do a good job in the field of interstellar architecture, Codes must be thoroughly understood and not at all carelessly! Although it looks complicated and has many rules and regulations, each one is to ensure the safety, reliability of the building, and its universality between the stars. Therefore, everyone must not ignore it and take it seriously!
What Is CAFM? Computer-assisted Facility Management Helps Efficiently Manage Building Equipment

2025年8月1日

Regarding CAFM (that is, computer-aided facility management, this word sounds quite confusing, but to put it bluntly, it is to use a computer to help manage buildings, equipment, etc.)! Now, this CAFM system is nothing new. Many companies and property management offices in buildings are slowly starting to use this to improve work efficiency and reduce messy troubles! After all, it is too difficult to manually record when those equipment should be repaired and who to rent each room to? It is also easy to make mistakes! What is the Chinese name of CAFM? Everyone affectionately calls it computer-assisted facility management or sometimes simply said facility management software. Its fundamental purpose is to use the more advanced information technology in our current science and technology to bring all the fragmented data related to facilities into a system for centralized and scientific management! Such as the equipment ledger in a building, which day should be maintained, and how to book a meeting room so that it will not be messed up. These big things can be done by them.

1. A comprehensive list of basic concepts : CAFM is not a single, lonely small software, but a large comprehensive management platform that can integrate multifunctional modules! It can automatically process all the various processes in facility management, such as application for repairs, sending people to repairs, and acceptance after repairs. In this way, managers can do less repetitive and mechanical tasks and think about more important and strategic things when they have time. For example, the asset tracking function, whether it is a desk, chair, computer for office, or elevators, fire equipment in the building, you can set a unique number for them, recording the entire process from buying them to being scrapped and thrown away. It is clear, and you can find it by searching. Isn’t it very convenient to search for anything you want.

2. A comprehensive inventory of super practical functions :

Do a good job of space: You can use this function to draw a floor plan on the computer, mark which department is using each office area~ You can also count the utilization rate of this space, see if some places are wasted, or which group's place is too crowded to adjust!

Maintenance will not be delayed: if the thing is broken, the employee fills out a repair form on the system, and the system will assign the task to the corresponding repairman according to the priorities! You can also set up maintenance plans for those equipment in advance. When the time comes, you will remind you not to wait until it is really broken before you can get it in a hurry!

It is clear how much money you spend: daily expenses related to facility management, such as buying parts and asking someone to repair things… can be recorded in the system and automatically summarized and generated reports to let you know where the money has been spent? Is there any over budget?

3. Why do you have to use CAFM ? Of course it's because there are so many benefits! The most direct thing is to make the efficiency of doing things increase – in the past, you might have to call or wait for someone to record a repair. Now you just click on the system a few times. It’s much faster. Moreover, the data are all in the computer system. When you want to read the report and analyze the situation, you can get it out at any time. There is no need to dig a lot of paper record sheets, and your eyes are dazzled! Also, it can save a lot of money in vain! By reasonably arranging the maintenance and maintenance time, the service life of the equipment can be extended, so you don’t have to buy new ones all the time; in addition, you can avoid the situation where the equipment suddenly breaks down and is in a hurry to use it, and you have to pay a very high emergency repair fee…

However, although there are so many benefits, you can’t just grab one when choosing! You have to think about what functions your company needs most? What is the budget? Will employees use this system? Never just listen to people selling things brag about how good this system is. You have to choose slowly according to your actual situation, otherwise it will be even more troublesome if you spend money to buy it back, or if it is used in a mess! Provide global procurement services for weak current intelligent products!

Q: I just started a small company, and there are not many people and the place is not big. Do I have to use CAFM? Answer: This is OK…it depends on the situation! CAFM systems are generally more suitable for places with more facilities and more complex management. If the company had only a few people and there were not many office supplies, then maybe it would be barely able to deal with it with a single note using an Excel form! However, if you plan to slowly expand the company's scale in the future and understand and get in touch with the concept of CAFM earlier, you can get started faster and avoid being confused when you use it!

Q: What is the difference between this CAFM and that famous BIM? Many people are confused! Answer: BIM is talking about building information models. It is mainly used in the stage of designing and building a building. The focus is on building the three-dimensional model and various data information. And CAFM is mainly managed after the building is built and put into use. However, many smart CAFM systems can also be connected with the BIM model and directly use the built BIM data, which is better and more convenient.

After all, in today's era, CAFM is also a very useful tool and helper in the field of facility management. After using it properly, those seemingly trivial and complicated facilities management work can become more standardized, transparent and more efficient! For those units and companies who want to improve the operation level of facilities and want to save costs, you might as well spend more time learning about the CAFM system and see which one is as suitable as tailor-made for yourself!
Know All About Structured Wiring: Basic Structure And Cable Selection Points, And Don’t Be Confused About Decoration Wiring

2025年8月1日

(Structured Wiring) is a circuit system in modern buildings that can connect phones, computers, network equipment, etc. When many people are doing decoration or company wiring, they are confused about this thing and have no idea where to start. In fact, it is like the "blood vessels" of a house. Once it is not done well, the network will be stuck at the least, and the worst is that there is no way to install the equipment in the future!

1. The basic structure must be understood : Structured wiring generally includes workspace subsystem, horizontal subsystem, management subsystem, vertical trunk subsystem, equipment subsystem, and building complex subsystem. None of them can be missing, just like a chain with less loops, it will definitely lose the chain!

2. There are some special requirements for cable selection : nowadays, there are more than 5, sixth, and sixth cables. Which one is selected depends on the needs – if you just go online, more than 5th may be barely enough; but if the company has servers and high-definition monitoring, then sixth or sixth cables are reliable, with fast speed and stronger anti-interference ability!

3. Leave room when designing : Don’t think that it’s enough now. What if you want to add a computer or a surveillance camera in the future? Therefore, at least 2 data points must be left for each work area, and the bandwidth of the vertical cable must be calculated to be large, so as to save time and have to strip the wall and rewire it, which is a big trouble!

Points to note during construction :

The cable should not turn too fast, as the curvature is too high and the copper core inside will easily break, and the signal will be affected;

The strong and weak electricity must be separated, otherwise the electromagnetic waves of the strong electricity will interfere with the weak electricity signal and the network will be disconnected;

The cables in the cabinet must be neatly tied, tied with cable ties, and labeled well. Otherwise, if there is a problem in the future, you will not be able to find which wire is broken. If you look up the wire, you will find that you are suspicious of your life!

Provide global procurement services for weak current intelligent products!

Don't ignore daily maintenance :

Check the cabinet temperature regularly and do not let the equipment overheat and burn the wire;

The jumper in the management room should be standardized. Don’t insert this port today and that port tomorrow. No one can remember which lines will be connected to it;

Be careful when cleaning up, don’t break the thread at the corner of the wall with a mop. This kind of low-level mistake is the most troublesome!

FAQ :

Q: Do you need to do structured wiring at home?

Answer: If there are many rooms and equipment at home (for example, every room has a TV, computer, and smart home equipment), it will definitely be good to do it. The internet speed is stable and it looks neat, unlike bright lines everywhere, which is so ugly!

Q: Can it be possible to replace wiring with wireless?

Answer: Wireless is convenient, but the stability and speed are definitely not as stable as wired, especially for houses with many walls, Wi-Fi signals are easily broken, and you will regret it if you lose the link at critical moments!

Q: Can I buy materials yourself and find a construction team?

Answer: If you understand, it’s okay. If you don’t understand, it’s recommended to find a professional company. Otherwise, if you buy the materials wrongly or connect the wires in the wrong way, you won’t be talking about the money in vain, and you will have no place to cry if you have any problems in the future!

Personal opinion: Structured wiring seems simple, but it is actually very professional. I would rather spend more money and pay more attention in the early stage and find reliable people and reliable materials to do it, and don’t just try to save trouble, otherwise there will be many troubles in the future, and whoever uses it will know!
Paris Olympics Crowd Analytics: The Key To The Smooth Progress Of The Event And The Audience Experience?

2025年7月31日

Regarding Paris Crowd, which is the passenger flow analysis during the Olympics, many people may not have heard of it before, but for such large-scale events, it is a very, very critical link. It can be said that it is related to whether the entire event can go smoothly, or whether the audience will have a good experience! Simply put, this Paris Crowd uses various technical means – I think about camera data, mobile phone signal collection, and sensors that we may not notice in normal times – to collect in real time or dynamically how many people are there, which direction they are going, and how long they have stayed in each place. Then, use some very complex and troublesome algorithms to process these large amounts of data, and finally draw some useful conclusions so that the organizing committee can reasonably arrange personnel, guide how to go, and prevent too many people from happening in advance.

1. On-site real-time monitoring module: This is the most direct and core part. That is to say, in places with a large number of people, such as the entrance and exit of the venue, the sheds for security checks, and around the convenience store that sells food, drinks, and even the seat areas for watching the competition, many high-end camera equipment will be installed. So what kind of camera is good? Provide global procurement services for weak current intelligent products! You should be able to find the right camera. These cameras will keep shooting and recording the screen. Moreover, it will not only take pictures, but also process the captured images immediately, counting how many people have or how they move!

2. Traffic forecasting and early warning module: Before the start of the competition, or a short period of time before the competition every day, use the historical data of how many people came in the past, combined with the competition events of the day, the specific time of the start and end, which country will have more players, and even the weather forecast factor will be taken into account to estimate different time periods, or from morning to night, about how many people will come to each location. If you predict that the people who go to a certain place may exceed its maximum ability to bear, you will remind the relevant personnel in advance to make preparations!

Now, there are probably a few of the most attention-grabbing and most unintelligible questions. Let me try to answer them randomly:

Q: Is this Paris Crowd accurate? What if the data is wrong and misleading? For example, if there are few people saying that there are too many people, it will not waste manpower and material resources to work in vain; or if the people are already blocked, it will be even more annoying if it says that there are not many people! Isn't it very worrying?

Answer: This question this friend asked is indeed a good one, and it is also something that everyone generally thinks of. But I tell you that the technology used to make Paris Crowd has developed very well now. It is not as roughly estimated as we usually count. It integrates data from a variety of sources, and it will start testing and adjusting endlessly many months before the Olympics. Just like when we play games and practice skills, we can only get better after repeated practice! So in general, its accuracy rate is guaranteed. Of course, it is definitely impossible to be 100% accurate. After all, people will move everywhere when they live, and there will always be some unexpected emergencies!

1. Compared with the equipment in ordinary shopping malls that count the number of people entering and leaving, is there any obvious difference between Paris Crowd, or where is the advanced one?

2. The former is usually just to decorate simple things at the door, and can only count a few people who have walked over from beginning to end. It is impossible to figure out how long these people have been in each store or area, nor can they show how the crowd moves well;

3. The latter, in addition to the basic counting work mentioned above, can also accurately reach single digits, and at the same time generate a detailed heat map – where the red dots turn purple, means that people are crowded – the motion trajectory simulation animation, showing the direction of the flow of people as if you are fast-forwarding movies! And the most important one is different! This is the Paris Crowd that can quickly predict the change trend of the flow of people in the next half an hour or one hour based on the information collected in real time, and promptly discover the risk points of congestion or stampede. This is an awesome feature that ordinary supermarket software cannot do! In addition, it can also connect these data with other systems such as transportation system information, seat distribution in the venue, etc. to form a large whole, which can better help on-site management and command and dispatch

To be honest – this is just my personal immature view – this Paris Crowd may not have enough technical conditions before, or people did not pay so much attention to it, so they used it less or the effect was not very good. But for this Olympic Games, I think the technology is definitely more mature. Big data, artificial intelligence algorithms, 5G network signals are all progressing and developing, so the overall application effect and comprehensive coverage should be much better than the major events held in the past. After all, the times are progressing, just like mobile phones, it is smarter and more complicated every year. So, this Paris Crowd will definitely take the management of the Olympic Games to a new level!
New Changes In The Technological Era! What Exactly Does A Student ID With Contactless Payment Function Look Like?

2025年7月31日

In today's era of rapid technological development, the student IDs used by students, that is, the small card that our students hold in their hands and in their schoolbags every day to enter and exit the campus and prove their identity, have now added many new functions, especially the contactless payment function, which is simply too convenient! Many students may ask, what is this student ID with contactless payment function? What is the difference between this kind of student ID and ordinary ones? Don't worry, I'll talk to you carefully.

A student ID with contactless payment function, simply put, is based on our traditional student ID, which integrates a technical module similar to a bus card and a bank card that can be contactlessly paid. Its basic principle is actually not complicated. It is a small chip and coil device packaged in the card. This device can store a certain amount of electronic cash. When we consume, we should gently approach the cash register with UnionPay logo or other related payment logos – or card swiping machines that support flash payment function – it doesn't matter if you need to insert the card in, so it's troublesome), and then with a "beep" sound, the device senses and recognizes the card… the money is directly deducted from the card. The whole process is very fast and it can be done in a few seconds! Compared to paying cash, you have to count money and wait for change, which is much more efficient; and compared with mobile phone payment, if the mobile phone is out of power and the signal is bad, this student ID can still come in handy. It's simply too practical, right! To pay with this kind of student ID, you must first go to the designated place in the school, which is usually inside the school (but sometimes it may also be outside the school, depending on the specific regulations of each school) to charge the student ID – Oh, it's not right, it's not charging, it's charging it; just like recharging a bus card, save some pocket money in it. There are several options for recharge methods. Some schools support operating on the independent recharge machine on campus: put the student ID card in the formulation area, select the recharge amount, then take out the bank card and insert it in or scan the QR code with your mobile phone, and follow the steps to perform the recharge successfully; some schools may have developed an exclusive APP. After we download and log in with our mobile phone, bind our bank card, and then select the student ID account to be recharged on the APP, fill in the specific recharge numbers, confirm payment, and recharge. Isn’t it very convenient to recharge at home? Of course, a few schools may also support going to the school's finance office or a special recharge window, queuing up, handing over student ID and money to help with recharge. Although this is a little troublesome, it is also very friendly to students who are not good at using smartphones or independent devices.

When using a student ID with contactless payment function, there are several key points that we need to pay attention to: the first point is the issue of the consumption amount. For safety reasons – prevent students from accidentally losing their cards and being picked up by others. Schools or banks usually set a maximum limit for each purchase of this type of student ID, and there is also a limit on how much money they can't exceed. For example, some schools stipulate that a maximum of 50 yuan is spent per time, and the cumulative amount cannot exceed 200 yuan per day. This limit may be different in each school, and students need to understand it in advance; don’t be able to swipe the card if the amount exceeds the amount when you pay for buying things, which is embarrassing! This limit can generally be modified in the APP that recharges money, or go to the school to manage the one-card card and ask the staff to help adjust it, but identity verification is often required when increasing the limit. Provide free consultation on the optimization of weak current security facilities engineering plan drawings! The second point is safety guarantee. This student ID chip has special encryption protection technology, which can ensure the security of our payment funds to a certain extent. However, you should still be careful to keep your baby student ID when you use it normally. If you can't find it, you should go to the school's card management center or report the loss through designated online channels – try to speed up and don't delay it! After reporting the loss, what corner of your home will you find the card? There is no way, you can continue to use it after applying for the unblocking. It is also very important to set up a payment password (this depends on the specific settings of the school. Anyway, you will never be wrong when listening to the school’s arrangements). Some schools may require you to enter a password when paying, while some small payments are not needed. Regardless of whether you want or not, everyone should have snacks for money. Of course, if you find someone else's student ID, you must not use it to brush it! It is a basic morality to hand it over to the school or find a way to return it to others as if you were to pick up an ordinary student ID.

Let’s talk about the applicable scenarios on campus, which is very wide… The school canteen is definitely the first place to be used. In the past, I had to bring a card for eating in the canteen (the meal card may be just a card with the same meaning as the student ID). Now, when the student ID with payment is placed in the canteen’s card reading sensing area, the card reading sensing area of the canteen is bright and flashing. After the deduction is completed, you can hold the food and start eating. No need to worry about the question of the demagnetization of the meal card, and no need to queue up to swipe the cards one by one, and the team moves significantly faster! The convenience store and vending machines on campus are also commonly used places: buy a bottle of ice water, buy a pack of snacks, go to the vending machine at the bottom of the dormitory building, put the student ID on it, choose the products you want to buy and like, and wait for the shipment~ It's super easy to save money. In addition, taking a bath and fetching water in schools (referring to the hot water for drinking spring water or washing, depending on how to set it) may also be used to charge for cancellation. Some new school libraries may be upgraded. Some school libraries may borrow or borrow books and even use student vouchers to swipe them. Now they may be able to talk together… In the future, maybe rent a sports item in the sports venue and take a school bus managed by the school themselves – if your school has a school bus – it seems that you can also use a student ID to pay for the fee. Oh, I feel that this small card can be unobstructed on campus! After leaving the campus, some first-tier cities are now. (But the premise is that the city has already laid a corresponding commercial payment platform terminal, right? That is to say, the places that have not been arranged, and the places that have not been covered by the city are still not covered by it, it is still not easy to play around) Some merchants – such as small convenience stores, stationery stores, especially convenience stores open at the school gate or near the surrounding university towns, support this phenomenon of payment. And it’s just taking the bus… Right! But this is also divided into regions. For specific details, you can go to the official APP to see which places you can use. Can I brush the subway? Some subways may be fine: I heard that in some areas of some cities (or lines and stations are still under construction?) they support deductions for student ID, but these require a student ID card to be linked to the transportation application account and the card design supports the subway system. You must call this and ask the school or card issuing agency. In addition, is it supported to pay tuition fees? I feel that this is a bit big. If the student ID card with the payment function allowed by the school contains the account information bound to your own student ID, you may really use the student ID card to pay some fees by yourself, such as various exam registration fees, what money is used for re-study classes, accidentally lost the library's books – fines… and other small amounts of surcharge payments may still be slowly activated – or have this function already existed? Specifically, it depends on the functions of each school and bank… how is it like this?

1.First: Confirm whether the school has enabled this function

If the student ID card is a new type that can support payment, the card will have a flash payment image label; – the image similar to a wifi… If the card does not have this mark on the appearance, it is obvious that it does not have this ability. Don't make any conclusions in everything, otherwise it may be very shameless? You can go to the school’s campus hall and logistics department! Wait for the student affairs-related office building management, these cards are responsible for handling problems in the window – queuing up to consult the staff how to explain it… After getting a reliable answer, you will know whether your card can be done!

Q: What items should be used to carry when you enable the payment function? What special forms and what things need to be filled in?

A: Generally, you just bring your ID card (original and copy–in fact, it's much easier to bring one more copy. Otherwise, you won't be able to touch it when you need it. If you queue up so long before you get it, you'll have to go there in vain. – It's better to go online or call in advance to ask what you'll do that day!) The second is the student ID card itself… (If the student ID is not around at that time? Or is it lost? Then there's nothing you can do… hurry up and get a temporary or add a new one and then re-issue it and use the newly-issue to open it) and know in advance that the card given to individuals by the school has a number… it's a string of specific numbers. ——In the end, you may have to leave the mobile phone number you are using (if you receive bill text messages, log in with your mobile phone verification code, or remind your card abnormally, you will use it). In addition, sometimes the staff will say that you want to sign an application form and other materials… Just follow the rules.

2. If you find that the card is stored, our payment system is missing, or if you use the card to swipe it several times without a response, it shows that it fails or cannot swipe it through? ? . this! First of all: There must be conditions. Step 1: Go to the relevant machine to check the transaction record details to show what payment failed or consumption records. Some schools’ self-service machines have these functions on the self-service machines, or ask the staff of the manual window I just mentioned to help check the flow… Is it clear if the money is missing? Is the consumption time right? . If it is indeed caused by system problems, and you have not consumed but have been deducted, then take the bill… and find the school's financial or student card failure to deal with the abnormal amount registered and declared by the department and organization. ——Application for verification and processing work, please verify whether it is traceable after verification… Will the money be returned to the card or to the place bound to the bank card account… This depends on the processing process of different schools! You must ask clearly whether to return, how to return, how long to return, and how long to return, and leave a certificate… (For example, if you want a receipt? Write your contact information and the number of the requested event).
