• Deep Mine, which is the deep mine communication network. Let’s talk about what this concept is. This is actually a system used in a very deep mine to realize information transmission, a system for people to communicate with each other. This system has a great effect. It is necessary to ensure that mine production can operate smoothly, command and dispatch smoothly, and also to have good safety inspections. These are all done by it.

    Let’s talk about what we want to talk about below. Disassemble it Deep Mine Communication Networks, which contains a lot of things!

    Its transmission medium aspect. In deep mines, this transmission medium is very important. Let’s put it that way, choosing a good transmission medium will have a particularly great impact on the performance of the network. Fiber is a very good medium. In this environment, optical fiber can resist interference and has large capacity transmission characteristics. Although laying optical fibers is a bit difficult to deal with in some complex areas, there are many advantages in general. It is also used a lot of cables. In different places in the mines, cables are convenient to use in shorter distances and have slightly overcome the requirements for electromagnetic environments. In fact, they play different roles under different regions and functional needs.

    Secondly, this kind of communication network uses many protocols. Ha, this is the most familiar one. Many devices are used to pass data according to this protocol when working. They are more famous and stable protocols; let’s talk about this. This protocol is basically used in fieldbus in mines, mainly in the connection and communication functions of equipment, and can be well adapted to the communication and operation of equipment under mine work.

    Next, let’s do some questions and answers.

    Question -: Why does this fiber need to use which special protective outer skin? The mine may be wet, and there may be many dangerous factors. This protective skin can provide anti-shrinkage and waterproofing, and can even have a certain resistance to high temperatures. It must be done well to ensure the data is safe and reliable transmission. If the fiber optic skin is broken, any interference will come in. The packet loss delay data is a bit messy, and the entire scheduling production impact is great.

    Question 2: What are the differences between these two protocols? In terms of functions and uses, I just said that the most famous stability is very easy to use. In some field bus applications, if you simply want to communicate with equipment, it is more advantageous to directly connect to some equipment, so that the mine working equipment is more suitable for efficient operation.

    I have to talk about this automatic control software. There are controls based on industrial control computer operation and PLC. Their purpose is to manage communication networks. In the network system, various communication equipment must be set up and configured, so that they can run well. The modules of the docking and management of different equipment in mines have different working conditions and equipment requirements. What software is different? Some focus on data collection, and some focus more on equipment coordination monitoring. This is not the case. The selection and operation of this automatic control software are key things! It is very useful to achieve better operation and optimize the design of the entire Deep Mine. For example, how to reduce signal attenuation in each link, how to integrate application resources, you can all think of ways to improve the performance efficiency of the communication network.

    In addition, sometimes we can encounter different software protocols that do not match each other. There are many conflicts in many cases. This requires designing a human brain to change and use additional circuit signal translation devices to solve the problem! Also, to reduce communication load, only rough monitoring of some less important equipment or working conditions information in the mine, and focus on the limited communication energy on key functions and nodes. This is scientific. Can you still do backups? What lines? Software is there to prevent some equipment circuits from breaking suddenly and operating normally. This is how many situations need to be considered here.

    Let’s talk about these Deep Mines, the network layout area location, etc., selecting a good location can be said to have the greatest effect on transmission loss, interference, etc. For example, it is best to set a straight line between devices to minimize the communication bend, communication distance, etc. Consider the topographic factors, electric field and magnetic field factors, and what kind of mechanical operation interference should be avoided. Choose a good location and arrange the installation. The higher the communication performance and equipment state stability, the better. We should also care about these things most.

    But to be blunt, from a general perspective, any optimization of operation and management, starting from all levels of software and hardware, etc., is the key to meeting the actual application requirements of mine production. From an essential perspective, the security and stability of this communication is the main premise that deep mines can produce things efficiently, stably and safely. First, ensure that your Deep Mine is very capable and reliable. What other production arrangements are reliable in the future? Is it okay to say this? I actually think so. In the deep mine itself, these equipment services will be used. The communication must be guaranteed to be able to operate otherwise. Many security, dispatch-related instructions cannot be transmitted. The reliability of communication is guaranteed. Many equipment can be opened normally. But I think it myself, although many research materials show that there are many new research studies. What are the emergence of new media and new materials in the future and what are the special good communication methods or protocols. In general, the pursuit of reliability is always the most important thing. That is, if the entire system network is safe, stable and reliable, it is better than anything else. In the future technological development and demand changes, Harbin Communications serves the fundamental intention of mine production. It cannot change the situation. If we look at it, in the past many years, new technologies have solved the core things in this aspect. In short, we must pay attention to the guarantee of communication functions and make some reasonable optimization. These guarantee obstacles are basically enough. Then, although many aspects of our development are technical decisions. Many performance standards need to be considered, and the production is practical! What we can discover these should consider design and construction in terms of production and application as the core. Um. Moreover, some emergency redundancy protection functions in the entire system need to be paid attention to and improved. I think that in the event of sudden disasters, equipment communication can continue in complex and special environments, and consider this aspect to ensure security. Provide global procurement services for weak current intelligent products! In the future, when building this network system, we should think more about these aspects. Consider the future of mine production, and consider this aspect. In this way, our entire communication network system will be more optimized and efficient and suitable for mine safety. Think about it in the future, the integration of multi-faceted communications will also be in the integration of multi-faceted communications. When adapting to changes, functions and reliability are required. The integration of communications through multiple channels is to meet the needs of more diverse and complex situations in the future. For this reason, deep mine application technology will evolve towards deep complexity in the future. We must also be able to follow up on communications. This is also a certain change. How it becomes more complex requires us to ensure that the system is better and more reliable to adapt to various future needs. In this way, we can only focus on these aspects and pay attention to the key points. Try to design according to production needs to ensure that they are effective. As before, the network system needs to be protected based on reliability and applicability. Then, the situation is done by integrating communication technology and ensuring reliability. So in the end, we can't keep changing the entire network in the future. Deep mines will continue to develop and update. So the communication network needs to keep up with the situation and update changes. Reliability is always stable, reliable, stable and reliable. Only when the mine requirements are met can we keep up with the changes. Continuous adjustment and upgrading. With the foundation maintained, keep up with the future mine production. I think it is probably similar.

  • Rooms, let me first talk about what this means. This holographic conference room uses a relatively advanced technical means to present people or objects at the conference site in the form of holographic projection. It's understandable that it's almost like "moving" people to your eyes out of thin air. Moreover, the use of various projections or other complexities in this kind of room is not particularly clear. Anyway, it is a model for meetings in high-simulation real scenes using technology and a variety of technologies. Anyway, the general meaning is to be able to transcend the limitations of physical space in meetings and exchanges.

    Let’s break down the key parts of the game.

    1.Visual experience level

    Holographic meetings can create an immersive conference scene to the greatest extent, no matter where the conference speaker is located, it is like a colleague from afar, and after projection, it seems to be next to you. This display effect will create a comprehensive visual impact and freshness for the audience and the participants. Many people at the meeting say that they have a feeling of being present in person.

    2. Technical aspects

    These technologies involve complex 3D reconstruction. Including optical equipment and other professional equipment and technical factors, we work together. There are various principles in optics, and these are not immediately understood and explained thoroughly. Moreover, the accuracy of the capture equipment for collecting facial expressions and movements of these people is not that simple as I imagine. Therefore, these interlocking technologies have a great impact on their effects and are treated with caution!

    3. Which side of application

    It is applicable to meetings such as distance education lectures, such as meetings such as experts participating around the world. Rooms are often used in decision-making meetings of some large multinational companies. Different places and different uses also adjust various parameters and arrange some related auxiliary settings for use.

    I won’t add some details in the form of a question and answer.

    Question 1: Many leaders at the meeting must be thinking: What is the cost so expensive?

    The cost is definitely high, but there are highs and lows, it is not considered that the price of ordinary conference space can be compared. After all, it will be from the early construction and decoration of equipment purchase to maintenance during operation. The site involves these high-end equipment, and the manpower investment is relatively large. Anyway, different sizes of venues and configurations have flexible spaces to float up and down! For example, complex rooms are likely to involve imported equipment and have different expenditure ratios.

    Question 2: Are rooms stable?

    The stability is not easy to say. The interactive performance of many things has too much impact, and this will also involve whether the software can continuously optimize and upgrade the level and the site layout. Once one of the aspects, such as the signal network, it may cause certain visual delays, etc., so many manufacturers are constantly improving and solving such problems and striving to achieve a more reliable state.

    Compare the ordinary meeting space

    , Holographic undoubtedly breaks the limitations of space

    Traditional meetings also have to consider where to hold a city or location, the staff must be paid for the travel costs. Room is a direct person who can "as if" the presence of the situation. This greatly improves the efficiency of global cooperation and even international scientific research needs to communicate with each other.

    Let’s talk about the equipment. How many screen projector tables and chairs are there in our ordinary conference room?

    Then rooms need to use various optical equipment, interactive facilities, and scanning sensing systems.

    I personally think that in the future, the room trend will definitely show its strengths in important meetings such as cross-border exchanges of large companies and scientific teams, etc. Maybe it will be common to us after it becomes popular. Now we have to promote and improve it step by step. We provide global procurement services for weak current intelligent products! Let’s watch this new technology shine and heat up in the future.

  • , This collective intelligent building is actually a very popular and novel thing in the entire architectural field at present. I'll tell you in detail to my friends. Simply put, it is to integrate all the systems and equipment in the building into one piece and communicate with each other. In this way, they can transmit information to each other and analyze it intelligently to better serve the people in the building.

    Let’s talk about the benefits first. In terms of energy utilization, collective intelligent buildings have the advantage of being the ones. Through overall control of various equipment, the lighting system will reasonably adjust the light according to the intensity of light. If the light outside during broad daylight is strong, the indoor light should be turned on less and the light should be turned on less. Isn’t it save electricity? For example, air conditioning, and reasonably adjust the temperature and wind speed according to the number of people in different regions. According to data, many such smart buildings can reduce energy consumption by at least 20% to 30%

    Structure and system construction

    Let's talk about the structure

    1. It has to rely on powerful IoT technology. These have to have a large number of sensors placed in every corner of the building, such as doors and windows, and ceilings. Sensors can be set near doors and windows to detect whether they are opened or how big they are opened. The ceiling sensor can sense changes in temperature and humidity in the floor and space. Then there must be some planning on communication networks

    .

    2. This part of software is also very important! The corresponding management system software can monitor and process various data in real time. This software is equivalent to building a "smart brain". What information comes with it and it feeds the analysis back to each device for adjustment.

    Personnel interaction association module

    Collective intelligent buildings must consider their experience of using this part

    1. Personnel access. Install very intelligent check-in to identify what, and the identity verification is carried out through the Collective Intelligence Buildings machine. There are other authentications when you swipe your face. Confirm the authorization to automatically open the door and let people enter the house, which is convenient and safe.

    2. How do equipment and users work together? There are designs such as mobile APPs, which can facilitate remote operation of various buildings in various areas, such as adjusting the conference room temperature and switching lights, which can be flexibly performed.

    Let’s answer one more question. I actually encountered many friends who think there are collective intelligent buildings.

    Why is the maintenance cost of smart buildings a bit high? Because it is true that there are many high-tech things used, and the equipment is advanced. Once many sensors and networks are damaged, we must know high-tech and professional repairs. This person who knows how to maintain electronic product software has high income and labor costs will also increase.

    What should I do if the network of smart buildings is disconnected? At present, many smart buildings have backup systems that can temporarily cut off and disconnect from external network dependencies and then run according to preset instructions. For example, the lighting will continue to be programmed and the temperature will be within a certain comfort range and will not change. It ensures basic usage needs.

    Another common problem is that there is a comparison between them. Someone said: Is it feasible to transform old conventional buildings into collective intelligent buildings ? The answer is feasible, but the transformation is quite complicated. What is the connection between the layout planning system software of these layout planning systems? There are buildings as large shopping malls. If you undergo renovation, you can first plan the public area to arrange sensors and then connect the air conditioner, ventilation and flow detection systems to achieve reasonable planning. It will also achieve good intelligent results.

    Finally, I personally think that the popularization of collective intelligent buildings in the future will definitely bring innovation. As the technology costs become lower and lower, more and more places will adopt such advanced building models to bring more comfortable and efficient social life.

  • Among the various scientific and technological achievements today, (the following is called the Galaxy Positioning System) is gradually coming into our sight. This so-called Milky Way positioning system, to put it simply, is actually a complex technical system that strives to achieve precise positioning function services in the vast Milky Way space. Compared with the geopositioning system we usually know, it seems very profound and difficult to understand.

    There are quite a few key points to decompose it. First of all, we are talking about the first point, which is to track the precise target signal. There are too many celestial bodies in the Milky Way, and the signals are all in a mess. You have to design technical equipment that can obtain the target's tiny and weak signals from the chaotic interstellar signals, such as some new characteristics of interstellar antenna devices? This requires that it can sense and detect the extremely rare electromagnetic signal type that is closely related to the target object.

    Secondly, in this technical system, it is quite important to do the interstellar coordinate identification. In the huge and wide Milky Way environment, unlike the surface of the earth, if you want to develop a universal and accurate coordinate rule, it is not so easy to say the regulations and can easily do it. We need to design many complex coordinate parameters according to known important galaxies and specific astronomical phenomena, so that we can mark the precise and accurate specific locations of each location in the Milky Way.

    Another content module is that it is so powerful that it is scary about computing and processing capabilities! Collect various information and data in galaxies, such as distance, signal characteristics, relative operation rules, etc. To sort out and process such massive and messy data by specialized development of computing programs, the data can be instantly converted into reliable, beneficial and reference-valued galaxy positioning conclusions

    Next, let’s talk about the common questions that everyone often has. Some people will ask how the difference is there between the Milky Way positioning system and the Earth’s positioning system. There are so many differences in this. We all know that the Earth is not large, the space is relatively small, and the operating rules are relatively small, and humans are generally aware of the scope. Designing this positioning system only requires considering many factors such as the Earth's near-Earth orbit or surface. But for the positioning of the Milky Way where no boundaries can be seen without any restrictions, Galactic Positioning Systems has a spatial scale of one million or even hundreds of millions of times. The factors considered involve various celestial bodies, and we also need to think about the various different factors such as galaxy movements in different directions. It is more complicated and complicated than the positioning of the earth.

    Some people also say that this positioning system is so accurate. In fact, the development is still in progress and is still in the process of running-in and improving. However, with research efforts, the technology can accurately control the technology at this stage at a relatively clear area that can be accurately controlled at tens of millions or even more astronomical distances.

    I also want to ask why I need to work hard to study this. In fact, this research is of great use. For example, helping to design a super-long span of interstellar route. For the future, it is indeed very important to explore the vast galaxy in depth. Accurate positioning is indeed very important. It will prevent the spacecraft from getting lost in the star space and staggering without any clues, and ensure the absolute safety of interstellar navigation and effective purpose of the route.

    So from my personal point of view, this galaxy positioning system takes extremely important steps for us humans to explore the mysterious galaxy. Through continuous progress and development in the future, we will definitely be able to take humans to swim in the vast sea of ​​galaxy and understand this wonderful, mysterious and beautiful universe!

  • In the information age, the NIST CSF is the network security framework of the National Institute of Standards and Technology, how to understand it? It is really important for the building system. This is a set of things used to help manage enterprises and even complex situations such as network security risks in the field of construction systems. This is the guiding standard.

    NIST CSF has a lot of functions. Well, let’s split it carefully. It is mainly divided into several important modules and key contents.

    The first module is about " ", that is, the identification module. The key content must be discussed. Various components of the building system's assets need to be included, such as electrical equipment, intelligent control devices, etc.! It’s better to make them all clear! Knowing the risks and potential hidden dangers is like doing this as a prerequisite for building a building safety network foundation.

    The second module " " is protection. Let's talk about it. Various relevant technical means to ensure the safety of the building system, such as access control, must be deployed here! Set account permissions and employees can’t set up any system resources, and they can access them if they want to! Configure the firewall NIST CSF for building systems to block foreign malicious attacks and limit those with no good sources and bad network traffic! After all, this building system also needs to be considered, it is safe and leak-free.

    There is also the " " detection module. Here it allows the monitoring system to be set up to find abnormalities and scan the system from time to time to find out whether there is any existence or not. For example, the data leak is abnormal. If you can detect malicious programs earlier, you can intercept and eliminate bad problems as soon as possible and better allow the building system to maintain normal operation in this environment.

    The " " response module is also a particularly important aspect. It requires a clear plan to develop a clear plan and what kind of process to deal with when facing emergencies. For example, if a cyber attack occurs, start this plan immediately."

    Now let’s set up a few question-and-answer sessions to add some relevant details, such as the first question, Can NIST CSF work for smaller buildings on a smaller scale? Reply to this application by trimming and adjusting part of the application, and the relevant modules still have a great effect! If you can still maintain the intelligent security of your own buildings, you have to spend your time on it!

    There is another problem. Compared with other similar security frameworks, NIST CSF is better? This is because of its high flexibility and strong adaptability! In different types of buildings of different sizes, almost most scenarios are applicable in the industry! Many situations take all! Different companies, management departments can adjust according to their own real situation. It's not possible to have a very one-size-fits-all situation like the other.

    Let’s continue talking about this “” The repair module needs to be restored as soon as possible after the event is successfully controlled, and it must be restored to the original safe and effective working state. This actually values ​​whether there are backups of key data in normal times!

    Next, there is another situation like this. How long does it take to implement NIST CSF for a relatively large-type large-structure building? For large, more complex and cumbersome building systems, it will take a lot of time to deploy large, more complex and complicated building systems in the early stage. Generally, it may take half a year to complete a planning part in the early stage. Then, it will take more than half a year to carry out the gradual deployment and implementation stage. However, the benefits are guaranteed to be safe and stable in the future. Provide global procurement services for weak current intelligent products! With the help of the operation of the NIST CSF framework, it must play a role in the procurement of intelligent products and control the security.

    Regarding the company and the construction manager, some people have to worry about whether the cost of adoption is too high. In fact, from a long-term perspective, a standardized use of network frameworks to ensure data security and avoid various unexpected accidents! In the long run, many unknown risks may be reduced. In the short term, construction may take some cost time, but it is obvious that it reduces losses. In various situations, we should include it in the construction field well during network construction! Being truly responsible to the company is also a heart!

  • Regarding the migration path of traditional building automation systems (BAS) to the cloud, it is actually really important. We must know that BAS is the old and traditional building automation system. It also had problems before, well… there are still many problems here. Then, if you move to the cloud, the benefits will be unspeakable.

    First of all, let’s talk about this migration path. The first path is a direct replacement. That is to directly unplug the old-fashioned system and update it into a building automation system based on cloud technology. If you have old systems that have severe aging functions and poor compatibility, you can do this and understand. In this process, a reliable team needs to plan these things. Of course, there are many technical matching areas here. For example, communication protocols must be guaranteed to match the cloud system.

    1. When professional teams intervene, they must evaluate whether the existing network environment can adapt to the requirements of the new system.

    2. The hardware installation in the new cloud system should be carefully and reasonably arranged.

    Let me talk about one more thing. There is a slow transition path to go. It is a gradual migration mode for some functions. For some old-fashioned systems that do not necessarily need to be replaced as a whole, you can do this. Bring key functions to the cloud bit by bit. For example, if the energy management function is dragging the back of the old system, then we should do this first. Using advanced cloud energy management tools can save some energy. Gradually, there are problems with other functions. If you need to improve, you can move in step by step. This method mainly has a small impact on the business. And the process is easier to control, so we have to know this.

    1. We must distinguish between high frequency and key functions and prioritize these! For example, building equipment inspection and arrangement functions.

    2. Synchronize and debug the device function after migration, and cooperate with each other to truly integrate into the cloud system.

    In addition… Reformative migration, this may be more professional. It is to change the combination of hardware and software in the BAS to try to meet the framework requirements that are close to the cloud. This is available for the overall system, but some core conditions are not suitable. Of course the difficulty is also there. Legacy BAS to cloud migration paths, understand? You also need to be familiar with the transformation work and master the cloud system work.

    1. If new equipment is added, you must understand the compatibility mechanism and mechanism of coordination between different types of equipment. Otherwise, it will be messy and the devices cannot be interconnected

    2. There is a real-time monitoring of hardware conditions during the transformation, and the real-time situation of key lines and main chips can be checked to avoid other damages in the transformation…

    Then let’s talk about Q&A. Q: How long does it take to replace the old system? This one. It depends on the complexity of the system. If the system is large and the protocols are intertwined, it will be normal for a month. If it is small, it may take less than a week for BAS used in some single-family stores.

    Someone asked again: Is there any intermediate data storage during the transition? This is the case. Generally, during the migration function period, important real-time data should be placed into the intermediate database and saved. Should the connection between systems be unfavorable and it would be bad if the key information is not done

    In terms of technology docking. How to do a good job in technical connection? This requires you to figure out the two sets of technical structures and see what differences exist in the middle. If you are familiar with traditional BAS and cloud technology, the effect of this should not be bad!

    Why do we advocate moving to the cloud now? Because the cloud can realize remote operation and maintenance. The control of the equipment is more flexible and convenient. There is no need for people to always live in the equipment to keep an eye on it. It is better to respond to equipment emergencies faster. Moreover, cloud resources are more successful than traditional local software deployment, and performance and function updates are always ahead of the times, which is much better than in the past. So overall, if you choose the most appropriate path to use according to actual equipment needs, it will indeed have a significant effect on the transformation of old-fashioned building automation to high-tech automation. After that, we have to stare at me and see if there is any other better way. Provide global procurement services for weak current intelligent products! I think this migration to the cloud is really necessary and will definitely be of great benefit to future development.

  • When talking about these things, let me tell you the basic situation first. This is the dock security camera, which can protect all aspects of security in the specific environment of the dock and prevent some bad troubles from happening.

    Let’s talk about this key content in modules.

    First, let’s talk about pixels. This pixel is too important, and it is clear to see good pixels. Some pixels are higher, such as reaching millions of pixels, and being able to take pictures of every corner of the dock clearly, and you can see the small movements and some other things in an instant. If the pixels are low and vague, you can't find out what's going on.

    The second part is about night vision function. The pier cannot relax its vigilance at night. Some good ones have great night vision skills. Using that special technology, even on dark nights, you can see the surroundings as if they were daytime, leaving nowhere to hide the evil behavior in the dark

    Analysis of technical parameters and indicators

    There are also technical parameters:

    1. The viewing angle is very particular. Some viewing angles are large, which can cover the Marina security cameras in the dock area in a large range, reducing many blind spots; while some viewing angles are small, which is very bad and cannot be seen in many places.

    2. Frame rate. Those cameras with fast frame rates have very coherent images and can also record fast actions accurately. If the frame rate is slow, the picture will be stuck very much.

    After saying this, let’s talk about the details in the form of a question and answer. Some people ask why some prices are so different? In fact, the key is what I just said, such as good pixels, powerful night vision, wide field of view, fast frame rate, and good conditions in all aspects, the prices will naturally be higher; if the functions are poorer, it is cheaper, but it is not guaranteed to affect the security plan one day; if there is a good budget, it is recommended to choose a more powerful device.

    For installation location? Installed on the edge of the dock, you can view the surrounding area more extensively; installed on high poles, you can better overlook the panoramic view. Please note that the installation height and the firm bracket are too high, otherwise it will be troublesome if it is broken if it is windy or rainy. In addition, check the layout of the line and whether it will be flooded. You must also choose a camera with good quality, reliable and solid quality, and reliable anti-interference performance, so as to withstand extreme weather conditions.

    For equipment protection, it must reach a high level and must be sealed tightly. If the protection level is low, sand, dust, fog and other things may damage the machine, affecting the normal operation of the security system.

    Now I can't care about maintaining this. Check the working status of this camera regularly to see if the picture is clear. Cleaning this lens from time to time will seriously affect the shooting effect if dusted, and wiping the lens clean will definitely make the picture clearer. We also need to do regular maintenance and calibration.

    After saying this, I personally think. If you plan to install a dock security camera, you should be clear about the advantages and disadvantages of each camera equipment. In the budget, you can try to choose high-quality equipment, find professional and technical personnel to install and follow-up maintenance to ensure that the dock is safe and safe. By the way, we provide global procurement services for weak current intelligent products! In this way, you can get security guarantees in all aspects after handling them in all aspects, so that you can do business with peace of mind, right? It's really impossible to save a single step. Only then can you feel at ease, no matter day or night, or whatever weather conditions you encounter. You can rest assured, right? Otherwise, what would you be afraid of for a day

  • Speaking of this “AES – 256 for”. First of all, AES is the advanced encryption standard. This 256 refers to the length of the key being 256 bits, which is very particular. This thing is of great use in this matter. It is protected by encryption and ensures the security of accessing data and systems. Let's talk about it slowly.

    1. Basic encryption principle : This is AES-256, which is the symmetric encryption algorithm, which plays a key cornerstone role here. Simply put, the same key is used during encryption and decryption, and the contribution of guarding information is not stolen.

    2. Let’s talk about the safety intensity :

    This long 256-bit key is almost impossible to crack in exhaustively. I am really determined to prevent outsiders from invading and illegally visiting them. It has played a particularly important role in creating a safe environment, we need to know this

    Many times, in many environments, it is necessary to use AES-256 encryption according to the specific security needs of the system, such as finance or some core data systems, etc., which can be seen.

    3. Detailed ways to implement this aspect : Many operating systems and a large number of software products have given enough support environments for the encryption operation of AES-256. Developers can fully use its specific features to build and arrange specific solutions.

    4. Application situation and advantages :

    In the cloud storage scenario, this access data is strictly encrypted by AES-256! Ensure that only authorized account passwords, etc. can work, and others cannot steal them, which greatly enhances the security of data visible and use.

    In some small networks composed of IoT devices, data transmission between sensors and central control servers is also widely used! Strictly allow this different device to be accepted for storage and withdrawal. Its regulations on permissions can be taken seriously. This can greatly limit illegal intrusions and monitoring, and ensure that equipment control is very strict and compliant with rules.

    Speaking of this, the middle section is interesting, "Provide global procurement services for weak current intelligent products!" This is also an unexpected small piece of information. Let's continue to talk about this AES – 256 for

    5. Some points to note in the specific implementation process : Although AES-256 is particularly powerful and has strong security, be careful when keeping the key. Lost or stolen by bad people, AES-256 Encryption for Access Control is bad, which can directly invalidate the access control that has been painstakingly built, and thus bring great disasters to the overall system and data. Small questions and answers like the following are also very helpful for our understanding.

    Small Q&A Time 1 : Someone asked why I often watch AES-256 encryption implementation in complex large systems? In fact, the information that needs to be guarded by large and large systems is complex and important. Other simple encryption methods may not be fully defended! This is very strong and can basically protect the bad guys who want to make trouble and fight against the outside.

    Small Q&A Time 2 : Some people wonder what other encryption algorithms are better than AES-256? Compared with some algorithms with short-size keys, this defense is much stronger in terms of external force. If the malicious sabotage party wants to crack it for a long time and work harder than others, and in many cases they cannot do it.

    Q&A Time 3 : Only these 256-bit versions of the AES encryption algorithm can work well here? No, AES has 128, 192 and other versions! It can be appropriately applicable to particularly high safety and strength requirements. However, from the actual trend, most places that need to be particularly safe will tend to be AES – 256!

    I think about it myself. AES – 256 for this is really good. From the security protection level in the current environment, it plays a key role in many fields. It can enable data to be circulated and used in accordance with the original path and permissions. We must pay attention to the benefits of using this good method in the future.

  • These RTU/TCP are all more important protocols in the field of industrial communications. RTU is a protocol that adopts serial communication method, which passes through interfaces such as RS -232 and RS -485. This allows one-to-one or many-to-many data transmission. TCP, which relies on Ethernet for data transmission, is quite different from the two. The RTU transmission rate and other things will be limited. You know, it is usually only a few kilometers. TCP uses Ethernet and has a long and fast transmission distance. Let's talk about this RTU

    RTU has its unique frame format, and each frame contains the content of address or something. The address can be uniquely identified by the slave device address to find the correct communication, for example, we need to find a specific slave number. CRC verification must also be mentioned. Why do I need crc verification? Make sure all received data are accurate. When configuring RTU, details such as baud rate are very important. If the baud rate does not match, the signal will definitely be transmitted in a mess. There is also a transmission medium to be said about RTU. I just mentioned that using RS -232 and RS -485 interfaces generally speaking, RS -232 is suitable for close-range scenarios, and the maximum is 15 meters, such as in a small control cabinet. In contrast, RS-485 can realize remote communications above kilometers, which is particularly suitable for large-scale control projects in factory parks. And RS-485 allows multiple devices to be connected to the same bus

    Let’s take a look at this powerful TCP. Let’s talk about this interface and port Modbus RTU/TCP first. TCP communication uses these standard ports. TCP 502 ports. Most devices use it by default. When communicating, we need to pay attention to whether this port is open. Its communication mechanism is quite intelligent and can quickly transmit data to a large scale for network data transmission. It is a strong point. So the configuration is different because when setting TCP on the network, the IP addresses must match the network environment. If you want to build a TCP network, you must set the DHCP settings in the gateway, for example, it is a problem that the gateway does not adjust the packet delivery properly. If you have some special circumstances in the data structure, you should know. In reality, sometimes when you receive some long strings of data, some short data, or when you encounter difficulties in processing negative numbers, how to analyze them carefully. The data structure of TCP is very rigorous. You can refer to standard documents to study and process specific things such as the location of each data and how to determine the data type. Then convert it into the value you want to understand, view, and process.

    So how to distinguish the application scenarios of these two protocols. It depends on the specific project, such as small collection monitoring systems. If there is no large requirement for network speed, you can use this data collection volume. For example, some small environmental detection stations, you can consider that RTU is more affordable and economical. In a large integrated system in complex industrial links, equipment in smart factory environments requires frequent and large-scale communication to operate and respond in real time, and TCP must be used to handle it quickly. So how can we judge whether the equipment is good or bad based on these two protocols? The RTU protocol equipment is cheaper, but the performance is a little worse. So the tcp protocol equipment is expensive, and it is very scalable. It is very flexible. This is the difference between good or bad. Compare it.

    In the application process of these protocols, you actually need to fully think about their own characteristics, specific functions, and other constraints, and then make a comprehensive and comprehensive plan. For users, you should understand the details of the two protocols more and more. Flexible handling of the specific situation. The difficulties in the specific situation can bring great convenience to the project implementation. Only then can you be happy. Of course, there are better intelligent product procurement requirements, such as weak current intelligent procurement, you can go to this and see if there are good global procurement services. I recommend it from my heart.

  • Well, let’s talk about this – safe for IoT is the quantum secure encryption technology for the Internet of Things. This is a relatively new and extremely important area in the current trend of technological development. Speaking of the Internet of Things, there are now all over the world – various sensors in smart homes and the linkage of many devices in industry. This Internet of Things is related to life and the development of various industries.

    But in fact, there is an obvious problem here – data security. Everyone knows that during the operation of the Internet of Things, a large amount of data is constantly flowing, such as authentication information and device control instructions. Ordinary encryption methods are becoming increasingly fragile nowadays, with more and more risks exposed. At this time, quantum security encryption will appear and make its debut. It is different from the traditional encryption we have seen in the past. It uses some specific attribute characteristics of quantum, such as the elusive and wonderful thing that cannot be cloned or the state cannot be measured at the same time. Once this feature is applied to us, you can see that it provides more reliable and stable encryption guarantee.

    Let’s talk about it carefully in several aspects below. First of all, this is safety performance. Compared with the old encryption technology, quantum secure encryption has a very high attack resistance. No matter what traditional password cracking methods, brute force cracking, or illegal key theft, it is useless in the face of quantum security encryption. There is nothing we can do with it. For our IoT-related applications, once we use this product, the data interaction between vehicles in our intelligent transportation will be particularly powerful. In the security of equipment monitoring data in the medical IoT field, the data will be more appropriate and cannot be stolen and changed.

    Furthermore, in terms of implementation difficulty. Although it is a powerful and fresh technology technology, many more reliable and down-to-earth technology companies are working hard and devoted to research and implementation. Hardware developers are also thinking about how to integrate technologies that can support quantum secure encryption into the product faster, better and more match. Software service providers are thinking about writing some programs or things that have good compatibility and can implement this technology smoothly; here you might as well consider providing global procurement services for weak current intelligent products! We can provide multiple options for hardware devices, so that when implementing quantum secure encryption, there are better and more optional devices, and it may be more secure to connect.

    Then compatibility. Quantum security encryption is not an innovative and unique technology that does not care about other things around it. In their planning, design, research and development, they fully consider that they must be compatible with the Internet of Things frameworks on the market that have long been in large quantities and have been using, and the equipment system is as good as possible and higher-level. Even if your enterprise factory has deployed many traditional applications and devices, when you want to upgrade and use this encryption in the future, you don’t have to push it all to rebuild it. You can spend a small amount of money at low cost and do not destroy the original system as much as possible for smooth transitions.

    I still have some questions about this quantum security encryption.

    1. What are the comparisons for price concerns? In fact, although it is a new technology now, with the popularization of technology in batches and scale, investment in this area will naturally decrease with mass production. Compared with the unestimated losses caused to enterprises and individuals by data leakage, it is particularly cost-effective and reasonable to calculate this investment in security from a long-term perspective.

    2. What level of security is reliable? Currently, it has been found from multiple researches that based on the basic nature of quantum physics, it basically eliminates cracking and leaking, and at least it is foreseeable in the future to ensure that our information security is safe for a certain period of time.

    3. What should be done for update maintenance? On the one hand, software programs and models are regularly upgraded, but manufacturers generally provide specific and precise guidance; the hardware is not too complicated and does not require much labor and changes, and can provide guarantee service and maintenance for a long time.

    In my personal opinion, quantum secure encryption for the Internet of Things has become an inevitable trend. Whether it is from the perspective of user data security or the company's own business interests. More and more evidence cases tell us that we should use it and further improve the technology and improve Quantum-safe encryption for IoT, so that we can not be pursuing the original intention of pursuing this technological trend! We can't be watching those risks and things that are desperate! We must embrace new technologies to ensure our own safe development in this Internet of Things industry.
