  • Interpretation Of Hive Mind Building Control: The Mystery And Key Modules Of Hive Mind Building Control

    Well… First let’s talk about this “Hive Mind”, which is the so-called honeycomb thinking building control. Let's give an example, it's like the collaboration between small cells in an organism. This control aims to integrate various systems in the building, such as lighting systems and air conditioning systems. You know this type of system is the right one, into an organic whole. It is just a matter of making it work better and more efficient.

    Let's take apart the specific key content. The first very important module is the equipment connection. To achieve this honeycomb-oriented building control, all related weak current equipment, such as security equipment ( such as cameras ), fire equipment, smoke alarms ( very critical thing ), etc., have many types to achieve smooth and effective connections, so that they can communicate with each other. Provide global procurement services for weak current intelligent products!

    Then, there is another key point in connection, which is standard connection. Unified standards are very important. For example, everyone must have a unified "language system" so that information transmission between devices will not be prone to errors.

    The next module I will talk about data processing. So many devices generate so much information and data, how to classify and sort out value? This requires us to have strong data processing capabilities to handle everything. First, let’s collect this data first. You have to obtain various on-site signals and data, right? Let’s talk about the data analysis module, which can determine the status quo and make decisions through data calculations ( just predict the trend based on existing data and adjust the strategy )

    There is also the user interface, which is the operation place. Whether it is easy to use, intuitive or not has a great impact on the experience of building management. The operation interface must be simple and bright to reduce learning costs.

    Let’s give us some questions and answers to add details, for example, why do we have to establish similar honeycomb building controls? That's simple, as I just said, let the entire building-related subsystem coordinate and cooperate to achieve the best efficiency, which can save energy, improve overall performance and experience~

    What is the difference between it and traditional building control? Hive control is a concept that is more integrated. It integrates data and shares information to support smarter and more convenient overall management decisions, etc. The control thinking is very different. Traditional controls mostly single-modular thinking such as single-modular control and do not work together to each other ;

    In addition, it is also added that there are higher requirements for operating stability. If data transmission abnormalities occur, it will be very serious if you are not good at playing the game signal and disconnecting; the overall control is closely related to the entire building.

    For the entire construction industry, including user management, I personally think that this will definitely become a major trend in the future, and will improve the efficiency of our modern buildings in all aspects, allowing buildings to become the home of intelligent management, and will definitely bring super leaps and improvements to modern life and office work.

  • How Important Is Cabinet Airflow Management? Related To The Stable Performance And Normal Operation Of The Equipment

    Regarding (cabinet airflow management), this thing is actually very important to many places where the cabinet is used. To put it bluntly, the air flow management in the cabinet can have a reasonable flow. This can effectively control the heat generated by the equipment and avoid local overheating. This kind of overheating is often the case – it will affect the normal operation of the equipment. We have to keep some fun here, otherwise it will be troublesome when there is a real problem.

    What is the important aspect of cabinet airflow management? Let’s talk about how many modules are separated.

    First of all, it can ensure stable equipment performance . I think if the air in the cabinet is not circulating well, the heat cannot be dissipated, and the cold cannot be in. Over time, many components of the equipment will easily degrade due to high temperatures. For example – if the computer server is placed in a cabinet with poor airflow – the calculation and data processing work in operation will be hindered, and maybe the response is slow, the operation is wrong, etc., who can withstand this. If the cabinet airflow management is done well, the temperature of each component in the equipment will be generally stable in the range that can work normally. The same computer server makes the data transmission smooth and there are no errors.

    Secondly, it extends the service life of the equipment . Everyone knows that high temperatures are particularly prone to damage to electronic devices, right? Various circuit chips are prone to age and degeneration after working in relatively high temperature environments. We usually work so hard to earn money to buy these cabinet equipment, right? If it breaks early, it will be unprofitable. If the reasonable air flow takes away all the heat – the equipment works in a relatively low temperature environment for a long time, it will reduce the wear and tear during work. Can it help us deal with it for a few more years, right? Just think about it, the electronic products I bought at home would have a longer service life if the temperature was always right. If you regard those equipment installed in the cabinet as electronic babies, it is not very important to pay attention to the air in the cabinet.

    Furthermore, the issue of energy conservation can be improved . Do you not think about this? Appropriate airflow can make the air conditioner more effective in cooling the cabinet – to achieve better results in this case, if the airflow is not paid attention to, it may be that the air conditioner is not effective no matter how large the air conditioner is turned on. For example, a 10-group cabinet room (given a number to understand) The airflow arrangement is not done well. The energy consumption of the air conditioner has always been high and the equipment is easy to overheat and crash and waste electricity, is it right and delay business; then plan this thing well and arrange the cabinet air duct and other things properly. In this case, the work efficiency of the same equipment has been improved and the power use of the air conditioner is reduced – it can save a lot of electricity.

    After talking about the key points of these modules, I will sort out the more practical details. I will mainly look at them in some Q&A:

    1. How can I control the cold air and hot air inlet outlet of the cabinet?

    Let me talk about it. First, let’s make sure that the cold air enters from the bottom of the cabinet. Then you can usually use grilles or mesh floors to better make the cool air outside run inside. In addition, hot air must be discharged to the upper part or back of the cabinet. Generally, fan modules can do this better (this way to squeeze out the hot air in the cabinet through exhaust)

    2. Will different equipment have any impact on the airflow in their layout?

    Let’s say that, the server or equipment placed in different heat dissipation systems is different – for exhaust equipment, you should pay attention to placing the middle point so that the surrounding air goes here, which is more convenient to integrate the flow with other equipment; while the blowing type is generally placed at the bottom or on the edge, and to supply cold air to the upper space (it is much more beneficial to the overall air distribution, and it is not easy to cause difficult situations such as heat accumulation).

    3. What auxiliary equipment is needed to ensure good cabinet airflow?

    Oh, that's quite a lot, for example, fan components are more important. The equipment that can be controlled with a certain amount of air volume, air volume, and other reasonable parameters such as air volume are very effective, which can allow stable circulation of airflow, whether it is suction or pumping; in addition, there are other things to be needed. Such as airflow baffles prevent turbulence in the cabinet and form air holes (these small problems will affect the heat dissipation) This accessories are installed in the inner panel and other key diversion positions; occasionally, filters are inevitable. Some computer rooms or cabinets are in a more dirty and dusty environment – then a suitable filter on the air supply port can block dirt particles – and cannot block too much airflow entry. These equipment is appropriately used to make it very stable and reliable.

    4. What should we pay attention to in daily management?

    You must pay attention to the inspection work in normal times. Take a look at these accessories periodically, for example, the fan motor may have faults and the filter will be dirty or blocked. Once a fault is found, replace the fan immediately; and the blocked filter should be cleaned quickly (clean about one or two months according to the certain usage conditions or check carefully every few weeks to see if it needs to be dealt with). In this way, through continuous and regular maintenance, we can ensure that it will not become unreasonable and lead to a series of accidents. It is also important to emphasize that controlling the temperature of the air conditioner equipment and the degree of opening the cabinet door is also necessary to control the details (if the door is too open, it is not good to run in outside heat, right? But sometimes it depends on whether there are enough workers during maintenance, etc.)

    Okay, let’s talk and explain it so well, it’s already quite complete for this. In short, I think this is not just a small matter. The air quality control problem inside the cabinet seems inconspicuous – it is really closely related to whether our equipment can work for a long time and whether the working condition is good (even the computer room environment, energy consumption and cost, etc. are related to this aspect, right?). We have to pay great attention to the key points of our daily operation and maintenance equipment selection and details in all aspects.

  • Smart Doorbell Analytics: Detailed Explanation Of Data Collection And Passenger Flow Analysis Of Smart Doorbell Analysis

    Speaking of Smart, this is smart doorbell analysis. That is to say, analyze the data collected by the smart doorbell and see how the visitor traffic is, when there are many visitors, how to use this device to make more security functions, etc. Let's talk about it in detail now.

    First of all, the first module is the data collection aspect. Smart doorbells can collect a series of various data, such as the specific time when a visitor rings the doorbell; and the total time the visitors spend from coming to the door to someone’s door. Various data similar to these will be recorded and stored by the doorbell. Of course, this also requires ensuring that the hardware of the good equipment is very stable and can ensure that the data is accurate without any problem.

    Then the second module is the passenger flow analysis part. From the collected data, we can see when the time period of the day is pressed frequently. These data analysis is particularly important. Using this analysis, we roughly know which node of a certain type of visitors is usually delivered during the day, so as to facilitate subsequent adjustments and arrangements to receive express delivery at home. If this is not the case, you may have missed a lot of express delivery. Provide global procurement services for weak current intelligent products!

    Let’s talk about the security monitoring utilization of the third module. With this smart doorbell collecting and analyzing data, you can make more use of it. If several abnormal doorbells are pressing data in succession, we must not be alert to take measures to ensure that the situation is not in front of the house. It would be much better to have these analysis to ensure security. However, many times you should pay more attention to the response to abnormal situations. Let’s talk about common questions and answers.

    Question 1: Is data analysis very much affected by device stability? In fact, just give an example. If the doorbell equipment has a bad fault record, then the results collected and analyzed will definitely not be very reference-oriented! The quality of this device is quite critical to the overall analysis process!

    Question 2: What are the application scenarios analyzed during peak passenger flow? Home living arrangements can be reasonably adjusted based on peak hours of visitors. For example, when ringing the doorbell, visitors do less important and brain-intensive work during peak hours. Many people also ignore this role and are actually important

    Question 3: Where is the difference between smart doorbell analysis and ordinary doorbells? If the difference is obvious! Ordinary doorbells can only implement the most basic doorbell button function, while smart doorbells collect a lot of data for analysis, and make more valuable decision-making and planning based on these. Overall, more deep functionalities are provided. Finally, I think that doing more analysis and research on this Smart can indeed better play the value of smart doorbells.

  • Cyborg Maintenance Interfaces: A Key Link In The Maintenance Of The Interactive Interface Of Cyborgs?

    This concept is actually about various interactive interfaces involved in cyborg maintenance. Let’s talk about this cyborg, it is not a simple existence like a pure mechanical or pure human in the traditional sense. This is equivalent to a key link in which the cyborg achieves good maintenance and ensures the normal use of functions

    First of all, in these maintenance interfaces, we will talk about this key content, which has hardware-related parts. Some problems related to the connection between sensors and body parts must be handled well in terms of hardware. For example, for a robotic arm, it is necessary to ensure that the interface and overall connection of this component is stable and signal transmission is stable. If this is loose, it will greatly affect its overall user experience and execution ability. This interface is very important to design scientifically and reasonably. This ensures that the docking is accurate and the adaptation issues between different components must be considered. This is one

    In terms of software, the operation control of cyborgs, command input, and various parameter settings must be processed through the corresponding software! It must be designed intuitively and easily useful, such as various error notifications and diagnostic results display, so that engineers can tell at a glance what is wrong, which can greatly reduce the repair hours. There is also an online upgrade function, otherwise you will not be able to keep up with new usage, requirements, etc. This is the key second point

    Let’s talk about data docking. You also know that many of these cyborgs’ operating data records, maintenance logs, etc. need to be uploaded, which requires a stable data exchange platform. It ensures that through the maintenance interface, data can be exchanged with the entire backend information center. At the same time, for operators and maintenance technicians in different positions, they must distinguish between permission restrictions and different responsibilities and do different things! This is also an aspect that needs to control key processing links in this regard!

    Let’s talk about important details of such questions through question and answer?

    For example, a master asked, if the hardware frequently plugs and unplugs some connectors, they may accelerate wear, how can this situation be avoided? This requires some high-quality and durable materials, and specialize in wear-resistant designs, such as the reinforcement coating process. It can minimize the possibility and harm of this wear and tear! Generally, if you plug and unplug it for five or six thousand times, there will be no obvious bad contact. Compared with hardware that does not have this design, the difference in service life will not solve the problem in a short time.

    What if there are compatibility problems when software docking? First, you have to check the software version and confirm whether it matches the control system! Let’s go further and see if the configuration file parameters are correct. Generally speaking, software providers will remind us to pay attention to this matter when updating programs, but we must also know it. By comparing past practical experience, confirming these aspects correctly can avoid up to 70% of software-level problems! .

    What should we do if these operators don’t understand the importance of data download and backup? This requires training and instilling important awareness. We set up regular backups, reminders, and other means to urge everyone to pay attention to it. We must do a good job of recording work to ensure traceability. Compared with other people who did not pay attention to backups or did not pay attention to operators, the probability of hidden dangers that arise later is much higher! The cost of handling problems after backing up the data may be reduced by about half!

    From the actual use and my personal point of view, it is really important to design, use and make good use of these links. It is the biggest help for the stable operation of the cyborg. If there is a problem, the whole impact will be great! There are so many bad consequences on the work of all parties, that is not a joke! Let's treat it honestly! It's really troublesome!

  • What Is Tier 4 Data Center Solutions Dubai? It Is Of Great Significance In Dubai. What Are Its Advantages?

    What is Tier 4 data Dubai? In fact, Tier 4 level data centers are of great significance in Dubai. Dubai is Dubai. I believe everyone knows that this place is very awesome and rich, and he is very concerned about IT in the local area.

    So we need to explain in detail what are the advantages of the Tier 4 standard data center. first,

    1. Extremely high availability. Basically, the operating state of 365 days, even 24 hours a day, will not cause major failures and interruptions, ensuring that your computer and equipment are connected to the Internet and any operations can continue to run. The corporate office software we use, such as financial software, employees have been inputting office operations in the financial software, and will not be interrupted.

    2. Extremely strong data security. For the super important commercial secrets or scientific research data stored in the data center, it is equivalent to wearing several layers of super security suits. It is difficult for others to obtain or steal. The boss no longer has to worry about leaking commercial secrets that affects the production and operation of the company.

    3. Super disaster tolerance. Whether it is a wind or an unexpected fire, even a special disaster situation, it can protect the data stability, all equipment and equipment in the data center are basically intact and continuous power supply, and can quickly resolve emergencies and avoid the expansion of losses.

    Next, let’s break down the relevant key equipment and facilities in Dubai’s local Tier4 standard data center.

    Let’s talk about the power supply part first. There are multiple power supply channels, such as multiple power supply companies supporting connections, and power generation equipment such as backup generators. If there is a sudden power outage, the power generation equipment will quickly rise and quickly provide power for the data center. Moreover, all equipped power supply and equipment components must be specially equipped with redundant backup components, such as:

    1. There are a large number of super high-performance power distribution switch cabinets, which allow data center equipment to receive power supply stably, continuously and reliably. If a line fails when it fails, immediately enable the backup line supply!

    2. Precision air conditioning system. It's hot in that place. For data centers, you need to pay special attention to maintaining a reasonable constant temperature and humidity environment, so that all components in the data center work smoothly and will not cause problems easily.

    Dubai Tier 4 standard data center air conditioning system is a 365-day, uninterrupted and caring for indoor equipment

    Then we will discuss the differences in the downwind-cold water cooling system. First, let’s talk about the cold water group. By circulating and exchanging heat with uninterrupted cold water, it can transport the huge amount of heat generated in the data center and finally discharge it to the outside environment. The water cooling performance is relatively strong and can cool the equipment better.

    The air-cooled system uses powerful power and a large number of cooling fans to achieve the purpose of promoting air circulation and dissipating the heat generated by the equipment. However, in the face of high heat dissipation in the data center, if the installation volume of the data server is too amazing or if it runs too many intensive tasks, such air radiator groups often find it difficult to maintain the temperature level within the strict range.

    In addition, let’s talk about the hardware architecture sector. The interconnection method between data center devices is very flexible and changeable. And when designed as a topological structure:

    1. Most of them are mesh links or tree structures that can enhance system reliability. This can help the data center to minimize the functional impact caused by accidents and failures in individual network channels.

    2. With a large amount of memory data processing equipment, high-speed running memory can quickly analyze and process a large amount of data input, so that all servers will not be paralyzed due to sudden business demand or information.

    Q&A session:

    Q: Dubai's Tier 4 data requires regular inspection of maintenance frequency, and why do you have to do this?

    Answer: You have to do a small check every week – simply check whether there is any looseness in the line connection, or whether the temperature sensor can get normal results, right? Each month, a relatively large-scale in-depth and comprehensive inspection must be arranged. This requires manual operation. For example, why do you do this? Because the data center is an operational production device. Even if it is a small mistake, it is not small. If a fault factor accumulates, it may cause a large system interruption event.

    Q: Is it a big investment to build a Tier 4-level data center in Dubai and how long does it take to take to build a construction period?

    Answer: The investment amount is really large! In the early stage of site selection – it takes a lot of money to purchase equipment and install these costs – it also needs to find a construction team to build supporting buildings, including computer rooms or cooling towers – it is not just about hardware – personnel training and maintenance, etc., all of which cost a lot. The construction period is estimated to take 2 to 3 years to complete.

    I personally think that the Tier 4 data center in Dubai is really good. For more commercial purposes in the future, it will definitely have greater potential. Moreover, the Middle East is now paying more and more attention to the information field. Maybe it is still to vigorously expand its international competitiveness and provide global procurement services for weak current intelligent products!

    We can only use the details of these basic hardware devices better if we understand them———————————————————————————————————————————————————————————————————————————————–

  • What Is Industrial PoE Switches? How Is It Different From A Normal Switch?

    PoE, we have to figure out what it is first. Simply put, this PoE is an industrial Ethernet power supply switch that can transmit Ethernet data signals while providing power to devices in need. We have to know that it is different from our ordinary switches

    First of all, its working condition adaptability

    1. In terms of temperature, compared to ordinary switches. The temperature changes in the industrial environment are not a little bit. It requires PoE to work normally within a relatively large temperature range. For example, many PoEs can be started normally in cold places at minus 30 to 40 degrees Celsius, or hot places at 50 to 60 degrees Celsius. For example, ordinary exchange machines are used in offices, and it is easy to get stuck in such an environment.

    2. It must also be able to resist humid environments! We know that most factories will have high humidity. PoE must withstand the interference of humidity changes. Even if the humidity reaches more than 90% of the relative humidity, it can still be in a state of operation tenaciously. Ordinary guys usually exceed a certain humidity and will damage internal electronic components.

    Secondly, related to power supply

    1. PoE is quite different when power supply is very powered. On the one hand, it supports traditional switches when they are often supplied with 110V or 220V AC power! Most products also provide access power supply operations for 12V DC or more commonly used in industrial industries! This greatly improves the flexibility of power supply in different industrial scenarios. In contrast, many general-purpose switches are purely docking in an energy-supply mode, and it is difficult to be flexible and flexible to combine with diversified power supply scenarios.

    2. And for sudden power outages. Many good PoE products on. Setting up UPS or similar power storage equipment inside quickly provides backup power at the moment the power is terminated. Keep important equipment from missing data or abnormal shutdown caused by sudden power outages! This kind of considerate life-saving setting is usually rare on ordinary switches!

    Furthermore, its data processing performance cannot be lost

    1. In industrial work, the amount of data transmitted is not a limit. PoE has stronger Ethernet data forwarding capabilities. The data forwarding and processing capacity of high-end products has reached thousands of Gbps! And the ordinary switches used in home office areas are simply hard to match!

    2. for more ports: It's also very important. The equipment in the factory is often connected to the same switch port with dozens or hundreds of units. PoE has many products that support up to 40 or even more than 60 physically available ports! For ordinary switches in offices, it is very rare to have such a high number of switches to 24-port.

    So how to choose the PoE that suits us:

    Q: How should I choose based on the industrial ambient temperature range?

    Well… In fact, we have to refer to the environmental parameters provided by this manufacturer. According to the actual temperature range, we often choose a specification slightly higher than the limit temperature PoE, which is safe.

    Q: What are the criteria for choosing the power supply port?

    What about this… I have to calculate the power consumption requirements of the equipment connected to PoE to supply power! To reasonably confirm the port according to power requirements, you must also combine the cable laying plan in the factory. Consider these lines together, and you cannot ignore the other.

    Q: What principles should be followed for switching bandwidth? ? ?

    That's it… the scale of communication data in the factory determines the bandwidth capability! Evaluate the amount of data in communication and have a control range of delays. Then you can choose the switching bandwidth matching product. For example, you have big data traffic flow processing requirements such as real-time video and audio! Products with larger bandwidth are preferred.

    So when it comes to this, our ordinary scenarios may focus on stable power consumption and functional satisfaction! PoE scenarios are facing the test of industrial complexity! It requires efficient and stable operation in harsh environments and under variable sudden shocks. Whether it is power supply, data transmission force, protection level, etc., it requires in-depth research and preparation in all aspects.

    Provide global procurement services for weak current intelligent products! I feel that the industrial industry cannot do without the fine use of this product, so that a relatively mature and stable ecological industrial network work network can be built!

  • What Matters About Access Control Management In Scientific Research Laboratory Are Related To Safety And Confidentiality, How To Do It Well?

    Speaking of access control management in scientific research laboratories [covering your face], it is not only a simple matter of who can enter and who cannot enter – it involves the security of bottles, bottles, jars, high-end instruments and equipment in the laboratory, but also the most important issue of whether the experimental data will be randomly flipped by irrelevant people! Now many units say that their access control system is so advanced, but when it is actually used, it is either because they have no response after swiping a card for a long time and are anxious, or the permissions are set in a mess. Those who should enter cannot enter, and those who should not enter are more comfortable. This kind of headache-in situation is really common! Provide global procurement services for weak current intelligent products! If you want to truly make the laboratory access control management safe and convenient, you have to calculate it from the most fundamental needs little by little, and you can't just look at the fancy functional settings on the surface.

    To understand what the laboratory access control system is, you must first understand that it is not the same as the access control that is casually installed at the entrance of our community – it is not simply "beep" and it will be fine. The laboratory access control system is essentially a comprehensive management system that can strictly control the entry and exit of personnel, and can also record in detail who entered which room at what time/what equipment was touched! The most core pain points it needs to solve include several real aspects:

    1. ▶ The problem of accurate identification of personnel identity! In the laboratory, there must be researchers, temporary foreign visitors, and technicians who repair machines, people of various identities walking around, but how can we ensure that only authorized people can enter specific areas with important things? This is a big problem

    2. ▶ The issue of flexibly adjusting permissions~ For example, a student may just help with laboratories in Laboratory A today, and maybe he has to go to Laboratory B to participate in another important project research tomorrow. At this time, his access control permissions cannot remain in the old state of the previous two days? If you can't adjust in time, it will be too delayed in your work

    3. ▶ The problem of recording and accountability of key operations… If one day one missing a bottle of precious reagents in the laboratory, or if an important experimental instrument was damaged by someone who didn't know how to operate it, if the access control system did not record these key entry and exit information and abnormal situations in detail, it would be really reasonable and could not be clear, and it would be impossible to find who did it.

    Currently, access control identification technology suitable for laboratory use is mainly common on the market. Each of them has its own advantages and disadvantages. You have to calculate and choose according to the actual situation of the laboratory:

    1. ▶ The old card swiping/password recognition method: The advantage of this method is that it is relatively cheap and it is not troublesome to install; but the disadvantage is that it is easy to lose a handful of cards by grabbing one handful of cards, and it is easy to be known by irrelevant people when they pass the passwords. And there is no way to accurately determine whether the person swiping the card and the card are actually operating the same person, which is very unsafe!

    2. ⌚ Fingerprint/face biometric methods: The advantage of this method is that its security has been greatly improved at once. After all, everyone’s fingerprints and face shape are unique and cannot be copied casually; however, its disadvantage is that the equipment is more expensive when buying it, and if someone is injured in his fingers, or has heavy makeup on his face, it cannot be recognized for a long time, and it is quite anxious to wait!

    3. ▶ Wireless sensing method for mobile APP/Bluetooth: This method is quite fashionable and convenient to use, and you don’t need to carry cards, keys, etc. with you; but it also has disadvantages! If the phone suddenly runs out of power and turns off, or if the signal is not easy to sense, then you have to stand at the door and can't get in. What should I do if it delays at that time

    When installing and using the laboratory access control system, there are still some unexpected small details that are not noticed, which may greatly reduce the effect of the entire system and spend money in vain.

    1. ▶ For door locks, you must choose one with "anti-trailing" function! Because some bad intentions will sneak behind people to sneak into the laboratory while the person with authority is opening the door. If this happens, it will be more scary than losing something! You should know that even a short delay of 0:00 seconds may give some bad elements the opportunity to take advantage of the "anti-trailing" function, which is to judge whether someone is coming in, so as to issue an alarm or directly close the door and completely block the bad elements outside!

    2. ▶ Pay special attention to the installation position of the card reader at the door~ Do not install it too low, otherwise people will easily be secretly seen by passers-by or passers-by when they bent down to swipe their cards! It cannot be installed too high, as short people cannot reach it, and it is inconvenient to generally install it at a place about 1.2 to 1.4 meters above the ground. It is a suitable and best position.

    3. ▶ It is best to connect the system with other equipment in the laboratory~ For example, if the access control system can be connected to key instruments such as refrigerators and incubators in the laboratory, when a person without permission tries to open these important instruments, the access control system will immediately issue an alarm and notify the laboratory management personnel at the same time. This is equivalent to adding a very reliable "protective lock" to the safety of the laboratory! Are you very smart? Provide global procurement services for weak current intelligent products!

    Some people who are just beginning to get in touch with the laboratory access control system may have some questions that they don’t understand or can’t figure out. Here are a few questions that are asked more to answer them briefly, so that everyone can understand more clearly in their hearts:

    Q: How long does the laboratory access control record need to be kept to meet the requirements?

    A: According to relevant regulations, it must be kept for at least 3 months! If there are often some secret projects that need to be kept confidential in the laboratory, it is best to keep them for half a year or even longer. If something really needs to be investigated in the future, these records are very important evidence, so don't delete them casually

    Q: Do visitors who come to the laboratory to visit temporarily have to apply for a temporary access card for him every time? Wouldn’t this be very troublesome and a waste of costs? Is there a simpler and more convenient way

    A: Nowadays, many advanced and easy-to-use access control systems support very powerful functions such as "temporary authorization QR code"! Before entering the door, the visiting guest only needs to ask the relevant experimenter responsible for receiving him to generate a one-time QR code with time limit. The guest can successfully open the door and enter by scanning the corresponding device with his mobile phone. In this way, there is no need to spend extra money to make cards, nor do they have to worry about accidentally losing the temporary card or being taken by the guest to swipe the card everywhere and enter some places that should not be entered. It is more worry-free.

    Q: If the power outage suddenly breaks down, will the access control system lock people in the laboratory and get out of the way? This is so scary

    A: Regular and qualified laboratory access control systems must have the safety protection function of "automatically opening the door when power is cut off"! This is the most basic safety requirement, so there is no need to worry about being trapped in the laboratory, which is a frightening situation~ After all, safety is always the first priority.

    I personally think that the laboratory access control system is definitely not a simple device that can be smooth when you buy it and transfer it to the door and power it on. It is more like a "safety butler" who needs to plan and design and carefully adjust and optimize according to the specific situation of each unit's laboratory! Instead of waiting for a problem to be secretly remediated, it is better to spend more time and invest a lot of money from the beginning, and choose a truly reliable access control system that can solve the actual problems of the laboratory – after all, no matter how much the laboratory safety is paid attention to, it is still worth it!

  • What Is ANPR Systems? What Key Modules Are Included? What Is The Actual Effect?

    Plate is what we often call ANPR. Simply put, it is a technical system for machines to automatically identify license plate numbers. It is widely used in many places such as parking lot management and traffic violation capture! Regarding the actual use effect and specific operation methods of ANPR, many people actually have a lot of questions like me – such as whether it is accurate or whether it is fast or not.

    ANPR mainly includes key modules such as image acquisition, preprocessing, character segmentation, and character recognition. Image collection is to take photos of license plates with a camera. This step is very important. If the photos are not clear, it will be useless. Pre-processing is to clean the photos, such as removing the shadows next to them, adjusting the brightness, etc., so that the license plate is clearer; character division is to separate each character on the license plate, such as "Beijing", "A", "1", "2", "3", "4", "5"; character recognition is to let the computer recognize what each separate character is, and finally combine it into a complete license plate number for us to show!

    There are several practical tips to use ANPR to help you avoid common pitfalls:

    1. Camera installation is particularly critical! Don't be too tilted. It's best to be aligned at about 45 degrees in front of the license plate. Too high or low will deform the license plate, and the recognition rate will drop suddenly.

    2. The light must be sufficient – there is good sunlight during the day. If it is dark at night, you must install fill lights. Infra-red infrared lights are the best. They will not shake the driver's eyes and can also brighten the license plate!

    3. Be sure to choose a lens with better performance – at least 2 million pixels, otherwise the small letters and numbers on the license plate will be blurred and the system will not recognize it at all, and it will be useless to spend money!

    ANPR FAQ:

    Q: Can ANPR still be used on rainy and smog days? ——A: Most systems are equipped with wipers or explosion-proof glass, and the effect is not great! But if the visibility is too low, such as if the big Fog cannot see his five fingers, there may be sporadic identification errors.

    Q: The old license plate fades very seriously. Can it be identified? ——Answer: This is indeed a troublesome thing. If the fading is too heavy, even if the human eye can't see clearly, the machine will definitely not be able to do anything. So if the license plate is old, it is best to go to the vehicle management office to change the new license plate as soon as possible.

    Comparing ANPR with traditional manual records, the advantages are simply too obvious: no one needs to keep staring at the license plate and manually marking numbers, saving a lot of labor costs! The recognition speed is calculated in seconds, and a car passes by "swoosh": some airports can handle 2-3 cars in one second! The data is stored directly in the computer and can be checked at any time. It will not be like a manual notebook that is accidentally lost and nothing will be lost! Another thing I want to tell you is to provide global procurement services for weak current intelligent products!

    After all, ANPR has really brought great convenience to our lives in the current situation of increasingly congested urban traffic and parking lots full of cars – especially managers, which are simply a good helper to liberate both hands! As long as the early installation and debugging is done, and the lighting is regularly inspected and maintained regularly, there will basically be no major problems!

  • With The Rapid Development Of IoT Technology, How Can IoT Integration Help Facility Management Solve Troubles?

    With the rapid development of IoT technology, people are paying more and more attention to the role of IoT integration in facility management. Many people want to know how to use cool IoT technologies such as IoT into facility management to solve various real troubles encountered in their work. IoT integration, simply put, connects various smart devices, sensors, and software platforms to enable them to communicate with each other and transmit data, thereby achieving intelligent management of facilities. Does it sound mysterious but also feel amazing? This thing is a good helper in facility management. It can help us improve efficiency, save costs, and make the facilities run smoother!

    1. In terms of equipment selection, this is the first step and a particularly critical step. We have to choose smart sensors and controllers with good compatibility, otherwise the equipment will not "talk" and it will be in vain. For example, when selecting a sensor, it depends on whether it supports standard communication protocols, such as MQTT and COAP, so that it will be convenient to integrate it later. Also, the stability of the equipment is also very important. You can't make trouble every few days, which will affect your work.

    2. Data acquisition and transmission module, which is like the "blood vessel" of the IoT system, is responsible for transmitting the data collected by the sensor to the platform. We can use wireless transmission technology, like Wi-Fi, LoRa, NB-IoT, etc. The specific choice depends on the actual situation of the facility. If the area is large and there are many devices, then LF-IoT may be more suitable because it has a long transmission distance and consumes less power. Moreover, during data transmission, security must be taken into account. Data cannot be leaked, otherwise the loss will be large.

    3. Platform construction is the core part, and there must be a useful platform to analyze, process and display the collected data. The platform is preferably modular and can be expanded according to different needs, such as access to energy consumption management modules, security management modules, etc. The operation must be simple and easy to understand. Don’t make it too complicated, otherwise it will be difficult for us people with low education to use it. Provide global procurement services for weak current intelligent products!

    4. Protocol conversion and integration, because different devices may use different protocols, there must be a "translator" to convert the protocol so that all devices can work together on one platform. There are many ready-made protocol conversion gateways now. We can choose the right gateway according to the protocol type of the device, which can save a lot of trouble

    5. Data analysis and application modules, the data collected is not a decoration, and useful information must be mined through analysis. For example, analyzing the energy consumption data can find out the reasons for the high energy consumption and then take measures to save energy; analyzing the equipment operation data can predict when the equipment may fail and maintain it in advance, which will reduce it.

    — Q: Will the initial cost be very high when building an IoT integrated system?

    Answer: At the beginning, you may invest some money to buy equipment and build platforms, but in the long run, it can help us save a lot of money! For example, labor costs can be reduced and equipment maintenance costs can be reduced. This can be evenly increased by in and out, and it can continue to save money later, which is a good deal.

    — Q: If the facilities are relatively old, can IoT integration be carried out?

    Answer: Of course! We can gradually transform, first install sensors and smart devices in key equipment and areas, and slowly build the IoT system of the entire facility without changing them all at once. That would be too much investment, and there would be no need to!

    However, it still depends on the situation. Some places may be in special circumstances, so this integration may not be necessary? ;Also, during the whole process, you will encounter various small problems, such as the equipment suddenly stops working and the data transmission error occurs. Don’t worry at this time, check step by step, and it will always be solved. I personally think that IoT integration in facility management is a major trend in the future. The earlier we are introduced, the sooner we can enjoy the benefits it brings. Don’t miss this good opportunity
