Weak Current System Integration Applications Are Widely Used, And Novices Must Know The Difference Between Weak Current And Strong Current

2025年7月20日

Regarding Low, which is what we often call the integration of weak current system, this thing is now widely used. Whether it is the small system used at home or the complex things in office buildings or shopping malls, there are many ways to go inside! Many people are yes with me when they first come into contact, and are confused and don’t know where to start… Some people can’t even figure out what the difference between weak and strong electricity is? In fact, simply put, weak current systems are the general term for systems with relatively low voltage and mainly transmit signals. Such as network lines, telephone lines, surveillance cameras, access control card swiping systems, and fire alarms, they are all considered weak current! Qiang Electric is the 220V and 380V that can be touched by the plug in our home to supply electricity. They are not the same thing, and it won’t work if you confuse them!

1. Clarifying the needs is the first step : you have to know first what you want to use for this weak current system? Is it just a simple network coverage, or does it mean that complex functions such as surveillance and video recording and intelligent building control need to be provided? My cousin suffered a loss last time. He said he could do it casually at first, but in the end he installed it, he felt that it was not enough functions, and it was uncomfortable and inconvenient here. As a result, he spent a lot of money to rework…

2. Choosing the right product is the key : it does not mean that the more expensive the thing, the better it must be. You have to choose according to your previous needs! For example, network cables are now the mainstream ones are the Super V and Category 6 cables – Category 6 cables have faster transmission speeds and better stability. There are also switches. Ordinary households with 100-100-megabit or 4-megabit switches may be enough (but the premise is that your network is really simple. If you want to upgrade in the future, you have to consider more specifications). If the company uses office scenarios, dozens of computers and hundreds of devices to connect and have various data transmission requirements, you have to use stronger performance and management functions! Here we provide global procurement services for weak current intelligent products! My neighbor started a company and found a lot of reliable goods on it before! .

3. The line layout must be planned in advance : Don’t wait until the decoration is done before you remember to set up weak-power lines. At that time, it will be a big trouble to dig the wall and trough it! How many network points are needed for each room, whether to keep the telephone interface, and whether to reserve the HD cable port on the TV background wall? You have to think longer-term… Don't drag the bright line when you don't have to be so messy, it won't be beautiful, and it will also affect your use

System compatibility issues must not be ignored! For example, if you choose, you buy a camera of XX brand, it may only be used with a video recorder of the same brand! If you don’t confirm it in advance, and buy a bunch of equipment and then don’t know each other and cannot connect and control it normally, then you’ll be done! You have to investigate one by one or exchange them! Also, the future expansion will be so good, and the maintenance will be inconvenient… It is said that technology is developing rapidly. Maybe in two years, your weak current system will want to add some new functions? If you don’t consider scalability at the beginning, the cost of remodeling will increase rapidly in the later stages, which will cause you a headache! !

Q1: Should I install Wi-Fi6 line coverage for the whole house at home? If the home is large, especially if it is more than 1200 square meters and there are many walls, it is really recommended to consider it! Wi-Fi6 has fast speed and high concurrency. However, the specific plan needs professionals to come to the scene, such as where to send signals (through those AP panels), the router chooses the power size and configuration model. After all, each user's home scene characteristics and house layout are different, and cannot be generalized! If you save money, you can consider Mesh networking. After multiple routers are paired, you can achieve seamless roaming switching, but there are also different solutions such as wired return or wireless backhaul, and the effects and costs are also different!

Q2: Does an intelligent weak current system require professionals to maintain and maintain? For simple and basic network and TV systems like home use, ordinary users can check it simply according to the instructions… For example, restarting the router, checking whether the Light Cat is working normally, etc. Basic operations. However, for enterprise-level complex applications including comprehensive security monitoring and comprehensive wiring, complex computer rooms, building automatic control, etc., they still have to be handed over to professional and technical personnel to get in touch with hardware and underlying systems, and they can only solve the problem quickly! Otherwise, if you make random troubles, the more you repair it, it will become more and more complete, and it will even affect the development of all offices and businesses in the entire company park (then the losses will be huge, it is simply incalculable, it is simply incalculable?). Maintenance also involves regular checks on whether the lines are aging and loose; equipment operating temperature, etc. are also important.

Personally, I think it is appropriate to find a professional weak current integrator to help you plan, design, installation and debugging on your doorstep, if you don’t really understand or do a family or friends in this field, you can do it in a more appropriate way! Although you spend more money on the early stage, you can avoid all kinds of troubles in the later stage because you don’t know how to do it. You can also save worry if you have guaranteed quality (saving worry is saving time and energy) right?
The Clues Are Revealed! Do You Know The Common Types And Applicable Scenarios?

2025年7月19日

Hello everyone! Today, let’s talk about the cable tray installation guidelines. This thing is a key role in electrical installation. Many people will encounter various troubles when actually operating, and don’t know where to start.

First of all, we have to make it clear to everyone that this cable tray is a shelf used to support and protect cable lines. It can make the cables arranged neatly and protect the cables from external damage. Common types include ladder type, pallet type, and groove type. Each type has its own applicable scenarios. For example, the ladder-type ventilation and heat dissipation performance is better, which is suitable for cables with large diameters and large quantities; the pallet-type has holes at the bottom, which can not only dissipate heat but also prevent some small things from falling in; the groove-type has better protection 😉, which can be dust-proof, water-proof and corrosion-proof. By the way, we provide global procurement services for weak current intelligent products!

When installing, the first step must be to determine the installation location and path. This cannot be determined by just patting your head. We have to consider the direction of the cable, load requirements, and whether the surrounding environment is suitable. We have to think about whether there are corrosive gases and whether the temperature is high. Then prepare materials and tools, bridge body, connectors, brackets, screws, etc., as well as tools such as electric drills, cutting machines, and leveling must also be prepared in advance.

Next is the specific installation steps, which are the key points, you have to look carefully:

1. Fix the bracket first. The spacing of the brackets must be determined according to the specifications and load of the bridge. Generally speaking, just like in a straight line segment, the spacing is about 1.5 meters to 3 meters, and the spacing at the turning point should be smaller, so as to ensure that the bridge is installed stably;

2. Then connect the bridge one by one. When connecting, use special connection parts and tighten the screws and do not loosen, otherwise problems will occur when used later;

3. When installing, you must also pay attention to the horizontal and verticality. Use a level to measure it from time to time to ensure that the error is within the specified range and looks beautiful;

4. If the bridge needs to pass through the wall or floor, it must be sealed to prevent dust and pests from entering;

5. Finally, install the cover. If the design requires a cover, the cover should be tightly covered and no joints should be left.

Here, I will also summarize some common pitfalls and avoid pitfalls:

1. The bracket spacing is too large, causing the bridge to bend and deform, which requires us to set the bracket spacing strictly in accordance with the specifications;

2. The screws are not tightened, and the bridge tray is loose after a long time. You cannot be careless when installing, and the screws must be tight;

3. The grounding treatment is not done well, and there are safety hazards. After the bridge is installed, it must be grounded, and the grounding resistance must meet the requirements👌.

Some people may ask: What inspections need to be done after the cable tray is installed? Well… Generally speaking, it is necessary to check whether the installation position of the bridge is correct, whether the connection is firm, whether the grounding is good, and whether the cover plate is complete. Some people may ask, is there any difference between installing cable trays of different materials? There must be some such as steel bridge frames and aluminum alloy bridge frames. The requirements for corrosion resistance during installation are different. The aluminum alloy bridge frame itself has certain anti-corrosion properties, and the steel bridge frame may need to be galvanized or painted.

Personally, I think that as long as you follow these guidelines step by step and operate carefully and carefully, the quality of the cable tray installation will definitely be guaranteed, and it will be worry-free to use it in the future. Be sure to remember that safety is the first priority and standardize construction!
Are There Always Problems With The Identification Of License Plates At Night? The Tricks And Solutions Are Here

2025年7月19日

Regarding the problem of identifying license plates at night, many cars enter and exit the community and parking lots at night. They can’t scan out or scan the license plates incorrectly, which is annoying! There are many tricks to explain clearly in this. We need to explain carefully what is going on and how to solve these problems… First of all, we have to understand what the recognition of night license plates is. Simply put, it is to use special cameras and computer systems to accurately "see" the characters on the car license plate on the dark nights and dark nights, and then record them and pass them to the system, so that the access control and charging systems can work normally without having to let the security guard register manually there one by one, which can save a lot of trouble and speed! Of course, the light at night is so poor, it is completely different from the daytime light and can see clearly, so its technical requirements, equipment performance, etc. are much higher than that during the day!

1. Let’s talk about the camera first : the light is dark at night, so the camera must be able to "see" it! So you have to use those with infrared lights or starlight cameras. The infrared may be fine during the day, but at night, you rely on infrared lights to illuminate the license plate, but sometimes it will reflect and be white; starlight, even if the light is not very good, it can capture a clearer picture, but the price may be a little higher!

2. Then there is the problem of fill light : relying on the camera alone may not be enough. In many cases, additional fill lights must be installed, such as white LED fill lights, or special infrared fill lights. The white fill light lighting looks a bit like the daylight, which can make the license plates taken very clearly, but they are a little dazzling to the passing drivers; although the infrared light is not very dazzling, the license plate number sometimes cannot be reflected due to reflection! Provide global procurement services for weak current intelligent products!

3. Also have the installation angle and position : the camera is not enough to be installed high or low! If you install it too far, you need to adjust the focal length. If you install it too close, the car will not be able to take a complete picture in a flash. Generally, you should pat the license plate on the front face, and don’t shoot it diagonally. If you shoot the license plate on the side, it will deform and the letters of the numbers will be crooked, so it will be difficult to recognize the software! It’s okay to have a little crooked body, but the license plate is the most important!

4. Talk about algorithm recognition ability : Even if the camera is taken clearly, you have to rely on the algorithms in the computer to "read" these numerical letters at night. Sometimes the license plate is dirty, or the reflection makes the words on the license plate light and dark, covering them. At this time, the algorithm must be smarter, be able to process the blurry pictures clearly, and turn the crooked license plates forward; for a complex background, there are street lights, neon lights and flashes beside them, and you have to ignore them. Some advanced algorithms can still be learned! The more license plates you see, the more accurate the identification will be!

5. Is the hardware equipment sufficiently configured : the relatively low-level identification equipment used to be old may have gone on strike or refused to recognize it at night! Nowadays, new devices generally use faster chips. If the processor responds quickly, they can process the pictures taken in one go, and the car will not wait too long. The resolution is also enough! A camera with only a few hundred thousand pixels can never be able to see the alphanumeric numbers on the license plate clearly at night. At least one pixel is more than 2 million pixels. The higher the higher the, the clearer it is. Of course, the storage must be increased!

Question: Why do the license plates in the front sometimes illuminate, but the license plates in the back of the SUV cannot be seen clearly and they are always identified incorrectly? -The main reason is that it has a lot to do with the model! Most SUVs are taller and have a little upturned buttocks. If the camera is installed directly to the front car license plate, the position may be a bit low and flat. When you take a photo of the license plate at night, the angle will be too upward – some license plates will hide under the bumper at the high point – and you may only be able to take half of the license plate. The fill lights and lights just didn't look right in the middle of the back license plate. In order to save trouble, some manufacturers only installed a camera on the aisle. There is no problem with the front license plate in front. After a while, the back license plate followed. The angle of the camera was not aligned, and it was dark and could not be identified. Then adjust the camera angle and lift it up by about 5 degrees, or install a small probe at the back to take pictures of the rear license plate!

Q: It’s so easy to identify license plates on rainy nights. Is there any practical solution? Isn’t it just a few sprays of defog deodorants? It is easy to have water beads on the lens on rainy days, so choose a camera with wiper function, or add a layer of specially coated anti-splashing film outside the lens*-water cannot be attached and will slip away in an instant! Filling light is also very important. There are narrow-angle fill lights for rainy days. Try to shine on a small part of the license plate, so as not to let the rain reflect the bright spots everywhere—and also, clean the camera and wipe it clean! ! Wipe it clean and take pictures to be clear and accurate! The drainage pipe on the ground needs to be done! ! The ground area is too deep – the water splash may flood the lower half of the camera.
What Is The Smart Building ERP System Jointly Launched By Siemens And SAP? What Can You Do?

2025年7月18日

Regarding the Smart ERP system jointly launched with SAP, many people actually don’t know what it is and what it can do, right? Simply put, this thing is to combine Siemens' hardware facilities in the field of building intelligence – such as air conditioning systems, lighting equipment, security monitoring, etc., with SAP's software technology in enterprise resource planning management. I don't know why it is so cleverly combined, so that the management of the building seems to be smarter and more trouble-free. Provide global procurement services for weak current intelligent products!

First of all, we must first understand the basic concepts of Smart ERP and its core goals. It mainly wants to integrate the operation data of various equipment, personnel flow information, and various resource consumption in the building into a unified platform for management; in this way, the managers of the building can see the various conditions of the building in real time through this platform, and make some analysis and decisions based on this information. The ultimate goal is to improve the operation efficiency of the building, reduce some operation costs, and at the same time, improve the experience of the residents or staff in the building, although the effect may not be particularly obvious.

If you want to really use this system well, you must know several key modules. Really, these modules are very important:

1. Equipment monitoring and maintenance module: This module will connect all Siemens equipment in the building, such as air conditioners, elevators, and fire alarm systems, and then collect their operating data all the time – such as temperature, energy consumption, and whether there are any abnormalities in operation. The system will also judge whether the equipment will fail based on these data. When it is about to break down, it will remind the administrator to repair it, and you don’t have to wait until it really breaks before you get fucked…

2. Energy Management Module: This is easy to understand. It is to record how much electricity, water, and gas are used in the building, and then analyze where it is used more and whether it can save energy; it can also generate some reports to let managers know where to start to reduce energy consumption and save money. Everyone is thinking, right?

3. Module: Why mention it? Because SAP's strength is ERP, the function of this module is to connect the building's management system with other systems in the enterprise, such as the financial system and human resources system; in this way, office space rental costs and operation and maintenance personnel scheduling can be combined with the management of the entire enterprise without having to manage each section, which is quite convenient…

Is there anyone else who wants to ask a question? There are probably some:

Q: Is this system good or not, so is it expensive? Can ordinary small companies afford it?

Answer: Well…however, this kind of system will generally have higher investment in the early stage, because all hardware and software must be matched; but after long-term use, it can still save you a lot of costs, such as energy costs and maintenance costs… For small companies, you can try it first by buying some functions, without having to buy them all at once…

Q: If the building used not Siemens equipment before, can it still be installed?

Answer: This… seems a bit troublesome, but it is not completely impossible; the system may be able to connect some equipment opened by other brands, but the effect may not be as good as Siemens's set. Moreover, it is estimated that it will take more time and more troublesome to connect the system…

Finally, I personally think that the + SAP Smart ERP system may be a useful tool for large commercial buildings – places like office buildings and industrial parks, or for companies with particularly high requirements for building management efficiency. Although it may feel a bit difficult to learn and adapt to this system at the beginning and need to learn a lot of new things, as long as it is used smoothly, the benefits to management work should be quite obvious!
Smart Sensors For Building Automation Technology Application Has Attracted Attention, And Smart Sensors Have A Great Effect

2025年7月18日

Smart for technology application is now attracting a lot of attention. These small, intelligent and advanced equipment have a great effect in improving building operation efficiency and living and office comfort, and provide global procurement services for weak current intelligent products! It brings more convenience to everyone to choose useful smart sensors.

Concept explanation… that is to say, the intelligent sensors used in building automation refer to those that can independently perceive temperature – not simply touch, but are accurate to a few degrees of zero, humidity, light illumination, whether there are any human activities, whether various gases exceed the standard, etc., and do not need to be manually stared and recorded, and can process data on their own or send it to other devices. They are small, inconspicuous but powerful electronic detection tools.

What key functional modules can these smart sensors implement?

1. Comprehensive monitoring function of the environment> You can monitor the actual temperature of every floor and even every room in the building – it will not be too warm in winter, it will not be too cold and consume too much electricity in summer, and the humidity – it will avoid moisture and mold, or it will be too dry and uncomfortable.

2. Intelligent control of lighting system >> It can detect whether there are people walking around, whether the light is bright or dark, and automatically turn off the light after people leave, or when there is enough light, saving valuable power resources. Isn’t it great?

3. Security auxiliary applications… When an abnormality is detected, or places such as doors and windows are illegally opened, the sensor will immediately issue an alarm, or notify the management center of the situation in a timely manner to make safety more secure.

Practical tips for choosing smart sensors

1. See how accurate it is! If you can't buy a sensor, the measured data will go up and down, and it will be completely inaccurate, so it will have no practical value…it will be in vain.

2. Incompatible with the existing system… If the newly purchased sensor does not match the system originally used in the building and cannot communicate and work normally, then you can only place it as a decoration and wait for it to fall into pieces!

3. It is very important and critical to the inconvenience of the installation… It is best to have no need to dig wiring around the wall, which not only saves money but also saves time. How good is that?

Q&A time! Everyone has common questions here…

Q: What's the best thing about Smart compared to ordinary sensors?

A: There are several main differences • Smart sensors come with data processing capabilities… Ordinary ones are just simple detection and then transmission! • Many smart sensors support networking… For example, Wi-Fi and Bluetooth can remotely know data, but ordinary sensors generally cannot do it. Q: Do you need to…maintenance after installation? ?

A: Generally, you don’t have to worry about maintenance often. Choose the ones that last a long battery life… For example, if you can use it for two or three years, you can check whether it is normal to report data. Don’t accidentally get damaged or use it and get damaged by a violent attack. Is it very worry-free?

My experience summarizes the field of building automation. Using the right smart can not only save money and cost less. Yes…it can also significantly improve the user experience and feel very comfortable! When you choose, compare various brands… Try to provide global procurement services for weak current intelligent products! , maybe the product selection is richer and there is more room for selection. Don’t blindly believe that products with very low prices and extremely outrageous boast about quality… are really important and super important!
How Important Is Prison Cell Surveillance? Revealing The Secret Of All-round Layout And Role

2025年7月17日

Speaking of prison cell surveillance, that is a big deal. In the current various security management systems, prison cell surveillance occupies a considerable position! It mainly uses a series of technical means, such as cameras and sensors, to control and supervise the inside of prison cells in real time.

First, let’s take a look at the importance of prison cell surveillance. First, it can ensure the safety and order of the prison . It is always staring at every move in the cell. If a criminal clashes, the prison guards can know and respond as soon as possible to prevent the situation from worsening further. Second, it helps in the management of prisoners . Through monitoring, prison guards can understand the prisoners' daily behavior and living conditions, and promptly correct any behavior that does not meet the regulations.

1. Monitoring equipment installation

Camera layout : When placing a camera, you must ensure that it can be seen in every corner of the cell. Like corners of the wall and ceiling, they must be installed and the angle must be adjusted well. For example, one should be installed at the door of the cell to see the in and out of the cell; one should be installed directly opposite the bed of the cell to observe the prisoner's activities on the bed.

Type selection: Generally, infrared, high-definition and wide-angle cameras are selected. Infrared cameras are suitable for use at night, and can be seen clearly even without lights; high-definition cameras can display the details of the picture very clearly; Wide-angle can expand the monitoring range and reduce blind spots.

2. Technical application level

Sensor technology : In addition to cameras, sensors are also quite critical. For example, an alarm sensor will sound to you once the window or door is opened abnormally and it will sound to you and call the alarm in time. There are also environmental sensing sensors that can monitor the temperature, humidity and air quality of the cell.

Data analysis technology : Nowadays, technology is developed, through data analysis, the behavior patterns of prisoners can be identified. If a prisoner has a regular routine and suddenly behaves abnormally one day, he might have to check what happened.

3. Data storage and management aspects

Storage method : It is generally better to combine local recording and cloud storage. Local storage means that there are special equipment in the prison to store monitoring data; cloud storage means that data is transmitted to the server on the network for backup, so that data storage is safer and can be found soon if you want to retrieve it in the future.

^Data storage time^: Usually, surveillance videos need to be stored for half a year to a year. If you encounter special circumstances, such as if you have a case trial, this video needs to be used as evidence, the storage time may be extended.

Let's get some questions and answers. If you don't understand anything about prison cell surveillance, you may answer it below

Asked, “Will surveillance affect the privacy of prisoners?”

Answer: In theory, prisoners must abide by various regulations in prisons. Surveillance is carried out to ensure the safety and order of the prison. As long as they follow the legal and compliant key points, they are monitored within a limited scope, which is not considered infringement of their privacy.

Ask, "What if the monitoring equipment fails?"

Answer: The prison must have special maintenance personnel to regularly inspect and maintain the monitoring equipment. If the equipment suddenly breaks, it must be repaired immediately and the prison guards will be arranged to strengthen patrols of the cell.

Compared with surveillance in general occasions, prison cell monitoring requirements are stricter, the scope is more comprehensive, and the data stability is high! Because it must make it more important to ensure that no problems arise between all parties.

Finally, I personally think that prison cell surveillance is really a very important part of prison management. With the continuous development of technology, its functions will definitely become stronger, and the ability to ensure the safety and order of prisons will naturally become stronger. Provide global procurement services for weak current intelligent products,! And in the future, prison cell surveillance will definitely develop in a more intelligent and efficient direction.
Programmable Substances Are Used For Dynamic Wiring, Can Automatic Adjustment Of Lines And Repair Faults?

2025年7月17日

Now let’s talk about this programmable substance for dynamic wiring. Programmable substances are those that can change their physical characteristics according to our instructions. Does this sound very magical? It's like it has its own "thoughts" and can change its shape according to needs. In dynamic wiring, this programmable substance can play a big role

Speaking of dynamic wiring, traditional line layout needs to change the direction of the line, so it has to be re-layed, but with programmable materials, it is different! It can dynamically adjust line connections, just like a live line.

So how do you use programming matter in dynamic wiring?

1. Automatic line adjustment : Programmable substances can automatically change the line connection according to system needs, and do not need to be manually adjusted one by one. For example, in a large electronic device, different modules need to reconnect the lines, and programmable materials can be handled by themselves.

2. Automatic fault repair : If the line fails, it can automatically detect and adjust the line, bypass the fault point, and continue to ensure the normal operation of the equipment. Just like a person can repair himself when he is injured.

3. Adapt to different functional needs : When the equipment functions change and different line connections are required, programmable substances can quickly adapt and rebuild the line.

What are the benefits of dynamic wiring with programmable substances?

Cost savings : reduces the cost of manual line adjustment and repair, and does not have to always buy new cables. For example, in a data center, if you use traditional lines, it takes a lot of manpower and time to adjust the lines, and using programmable materials can greatly save costs.

Improve efficiency : It can quickly respond to system changes and ensure that the equipment can adapt to different working conditions faster. It's like a racing car has a super flexible transmission system, which makes it more exciting to run.

Space utilization is more reasonable : there is no need for a lot of fixed lines to occupy space, and the lines can be flexibly arranged in a narrow space as needed.

So, are there any tips during use?

1. Accurate programming : Write accurate programs for programmable substances so that they can accurately adjust the lines as required. If the program is not well compiled, it may be messy and the lines will be messy

2. Regular inspection : Although it can repair itself, it still needs to be regularly checked to see the operating status to ensure that it always works normally.

3. Compatibility with existing systems : It is necessary to ensure that programmable substances can be compatible with existing electronic systems, otherwise they will not be able to play a role.

FAQ

Q: Will programmable substances lose their "programming ability" after being used for a long time?

Answer: Generally speaking, as long as you use and maintain it in the correct way, you will not lose your programming ability. But if the environment is too harsh, such as too high a temperature and strong electromagnetic interference, it may have an impact.

Q: Compared with traditional wiring, is it particularly expensive?

Answer: The cost may be higher at the beginning, but in the long run, the cost savings can make up for the early investment. Just like buying high-end energy-saving appliances, it is expensive at the beginning, but it saves a lot of electricity bills after using them for a long time.

Q: Is the installation complicated?

Answer: The installation process is actually not complicated. It mainly connects with the existing system and then writes the program. But you need professionals to operate, otherwise you will be afraid that the installation will not be good and will affect the performance.

Some comparisons

Flexibility : Traditional wiring is fixed and difficult to adapt to changes. Programmable materials can be dynamically adjusted, and have high flexibility.

Maintenance difficulty : It is very troublesome to find fault points for traditional wiring maintenance. Programmable substances can be self-detected and repaired, making maintenance easier.

Provide global procurement services for weak current intelligent products!

I think programmable substances used for dynamic wiring are a big trend in the future. It can bring great changes to electronic devices and systems, making line layout smarter, flexible and efficient. With the development of technology, it will definitely become more and more popular. Maybe in the future, the electrical circuits at home will all be made of programmable substances!
MQTT Is Used For Legacy System Integration: Lightweight Protocol, Many Benefits, Great Decoupling

2025年7月16日

In today's era of rapid technological development, MQTT for (MQTT is used for old system integration) is actually a very important and meaningful MQTT. It is a lightweight message transmission protocol and has a wide range of applications in the fields of the Internet of Things and other fields. For old systems that have been used for a long time, MQTT has played a huge role in integrating with new technologies to achieve this.

First, let’s take a look at the benefits of MQTT for legacy system integration. First of all, its communication overhead is extremely small, and it can complete the message delivery with very few resources. This is simply too good for the old system where hardware resources may be relatively limited! Second, it follows the – (publish-subscribe) model, which can well achieve decoupling between different components, making the interaction between the old system and other parts simpler and clearer.

So in actual operation, how to use MQTT for old system integration? The steps are as follows:

1. Choose a suitable MQTT proxy server. This is very good, and its stability and functionality are reliable.

2. Abstract the data in the old system and convert it into a message format that MQTT can process.

3. Write connection code so that the old system can successfully connect with the MQTT server and realize data exchange.

Provide global procurement services for weak current intelligent products!

In order to ensure the integration effect, many key points must be paid attention to! Safety aspects should be considered. Although this matter has been mentioned, TLS encryption must be used to ensure the secure transmission of data. It is also necessary to evaluate the performance of the system and adjust the QoS (quality of service) level according to the characteristics of the old system to avoid excessive load, otherwise it will affect the stability of the entire system.

Here are some details for everyone in the form of FAQ!

Q: Will integrating the old system into MQTT have a big impact on the operation of the old system? Answer: Generally, the impact is small. Through reasonable optimization of configuration, there are no major changes to the operation of the old system, just adding point data output.

Q: Is there a size limit for MQTT messages? Answer: Well, there are basically no strict size limits, but considering transmission efficiency and storage, it is best not to send particularly large messages.

Let’s talk about the comparison with traditional integration methods. Traditional methods often rely on a large number of interface development and dedicated line connections, which are expensive and troublesome. And MQTT integration is much more flexible, low cost and faster development. Its lightweight feature allows the old system to be integrated without making too much changes, which is incomparable to traditional methods

There are also different strategies for integrating MQTT for legacy systems in different industries. For example, in the industrial field, old systems often need to be integrated with sensors and other devices, and the low latency and real-time performance of MQTT can solve monitoring and control problems well. For example, in the medical industry, when old information systems and new mobile devices are integrated, MQTT's communication mechanism can ensure timely and accurate data transmission.

To be more practical, you can also try to get some data cache measures. When the network is disconnected or the system is too busy, you can temporarily store the data and send it when the conditions are improved to avoid data loss. It is also necessary to build a log monitoring system so that the system can be observed at any time and can be found immediately when there is any problem, ensuring the smooth operation of the entire old system integration. For old systems driven by sensors, MQTT client functions can be added to the sensors, allowing them to directly pass data to the MQTT server, and can also reduce the computing pressure on the local system. There are often various requirements in the integration of old systems. We can develop special plug-ins or modules according to business needs, so that the old system and the new system can cooperate more perfectly. You can also build a test environment, first do some simulated integration tests, see the effect before implementing it formally.

In my opinion, MQTT for has strong adaptability and flexibility. It builds a good bridge between the old system and the new technology, allowing the old system to continue to play a role in the new era.
What Is The Highly-watched Forced Code Feature? Introduction To Type And Installation Steps

2025年7月16日

Regarding the topic of forced code function, which is currently attracting much attention, let’s talk about what it is! Forced code function is actually a mechanism that can play a big role in specific dangerous situations. When the user is in a forced state, the system can respond accordingly by inputting a pre-set forced code.

It mainly has the following types:

1. Alarm trigger type : Once a forced code is entered, the system will immediately send an alarm message to the security department, which can quickly attract the attention of the outside world and ensure the safety of the user.

2. Information transmission type : This type can quietly convey important information such as the user is in a dangerous state to designated personnel.

3. Camouflage operation type : After entering the code, the system surface maintains normal operation, but in fact it is already conveying the dangerous situation or is ready to deal with it.

Here are the steps to install the forced code function:

1. Determine the requirements : clarify in which scenarios you may use the forced code function, and then choose the appropriate system or method based on these requirements.

2. Select a product : This step is very important. You need to choose products with high stability and reliable performance, otherwise it will be troublesome to lose the chain at critical moments.

3. Installation and configuration : Perform correct installation and configuration work in accordance with the product instructions to ensure that every link is accurate.

4. Test and adjustment : After installation, conduct multiple tests to see if it can be triggered normally and make adjustments to inappropriate places.

Let’s talk about the skills of using forced code functions:

1. Remember the code : Be sure to keep the forced code in mind, so as not to remember it in an emergency, that would be a bad thing.

2. Avoid exposure : You should not tell others your forced code easily to prevent it from being exploited by bad people.

3. Regular updates : To increase security, the forced code should be replaced regularly.

4. Cooperate with other measures : It can be used with other safety measures, such as setting up emergency contacts, etc., to enhance the protection effect.

Let's take a look at the difference between forced code function and ordinary code function:

1. Different usage scenarios : The normal code function is used when using the system normally, while the forced code function is specifically used in dangerous forced scenarios.

2. Different working mechanisms : ordinary code functions run according to normal operation process, and forced code functions to trigger a special security mechanism after input.

3. Different purposes : The ordinary code function is to facilitate operation and utilization of the system, and the forced code function is mainly to ensure the safety of the user.

Here are some FAQs and answers:

Q: Is the forced code function easy to be cracked?

Answer: As long as you choose products with good quality and advanced technology and take confidentiality measures, it is generally not easy to be cracked.

Q: Does it require professionals to install the forced code function?

Answer: If the product is more complicated, it is best to find a professional to install it, so as to ensure the correctness and stability of the installation.

Q: Can the forced code function be used on all systems?

Answer: No, some systems may not support it, so you must confirm the compatibility of the system when choosing.

I personally think that the forced code function is indeed a very practical security measure. In today's complex and changeable social environment, it can provide people with additional security protection, and it is always good to have an extra layer of security! And if everyone uses it in the right way, they will definitely play a greater role!
Global Procurement Service For Weak Current Intelligent Products! Are These Dark Sides Hidden Behind Smart Buildings?

2025年7月15日

"Provide global procurement services for weak current intelligent products!" When it comes to smart buildings, everyone generally thinks of high technology and convenience. In fact, there are really some unknown "dark sides" behind this smart building. Smart buildings are buildings that use various advanced technologies to automatically control and manage various systems of buildings.

Potential crisis in energy management

1. The energy consumption data is not real

Smart buildings rely on a large number of sensors to collect energy consumption data, but sometimes these sensors are unstable, or problems occur during data transmission, which will make the energy consumption data inaccurate. This will lead to a mistake in energy management strategies and waste of energy. For example, there is obviously no one in the room, but because the data is inaccurate, the air conditioner is still blowing.

2. Blindly rely on the regulatory system

The energy control systems of many smart buildings rely too much on program settings. The weather suddenly changes, and it cannot be adjusted in time, and it still operates in the original mode, which will cause unnecessary waste of energy.

The Challenge of Cybersecurity

1. System vulnerability risk

Various systems run in smart buildings, and these systems will inevitably have loopholes. If a hacker is on the target, he can use these vulnerabilities to invade the system and control the equipment in the building, which is dangerous! Any elevator, lighting, and security system may be controlled.

2. Data breach threat

Smart buildings collect a large amount of user information, such as entry and exit time, usage habits, etc. Once this data is leaked, the user's privacy will be out of protection and may even be used by criminals to commit crimes.

Disparity in user experience

1. It is complicated to operate

The operating interface of some smart buildings is designed too complicated, and ordinary users don’t know how to use it. I wanted to adjust the temperature, but it was wrong to order it for a long time, which greatly affected the user's user experience.

2. Lack of artificial intervention

Smart buildings emphasize automation, but sometimes when encountering special circumstances, manual intervention is required. However, some buildings have few ways of manual intervention or are troublesome to operate, which makes users feel inconvenient.

FAQ

1. Question : Can energy waste occur in smart buildings be discovered and adjusted quickly?

Answer : Not sure. Due to the inaccurate energy consumption data mentioned above, it may be difficult to detect energy waste in time. Even if it is discovered, adjustment will take time and appropriate strategies.

2. Question : Are there any good precautions for smart building network security?

Answer : The system can be regularly inspected and repaired vulnerabilities, installed firewalls, and network security training for employees to improve security awareness.

3. Question : How to solve the problem of complex user operations

Answer : Construction developers can simplify the design of the operating interface, provide detailed instructions and training, and can also develop mobile applications to make operation more convenient.

Compared with traditional buildings, although smart buildings have many advanced aspects, there are indeed many problems in energy management, network security and user experience. Overall, I think smart buildings are a good thing, but only by constantly improving and solving these "dark side" problems can we truly bring convenience and safety to people.
