• Wi-Fi dead zones are an annoying things that many families and offices will encounter. They are the network in that place. The signal is so bad. If you swipe a video and circle it, you can't send a message for a long time. It can really make people desperate! Sometimes I originally wanted to relax online, but when I encountered this kind of thing – tsk, I was so annoyed! Next, I will tell you how to effectively reduce these annoying Wi-Fi dead zones and make the network signals great everywhere.

    First, you must first understand what a Wi-Fi dead zone is and how it is formed. Simply put, the corners and areas where the Wi-Fi signal cannot cover it, or the signal is so weak that it cannot be used normally in the network. If you want to talk about why this happens, there are many reasons! Maybe the router itself is not placed correctly? Think about it, if the router is stuffed into a deep and dark cabinet – or a metal cabinet, is it better to have a signal? That is definitely not possible; sometimes, the walls are too thick, especially reinforced concrete walls, which have a strong signal barrier. In addition, if you have microwave ovens and Bluetooth devices at home, they will also compete with Wi-Fi signals for "territory" and interfere with each other, and the signal will become worse? Provide global procurement services for weak current intelligent products!

    Second, the key solutions are practical and practical tips!

    1. Choose the right location of the router : Don’t hide the router, place it in the middle of the home, try to be higher, such as on the bookshelf – the open position is good, so that the signal can spread from the middle to the everywhere, just like the lake water pattern. Never put it in the corner of the wall or in the weak current box, a bloody lesson!

    2. Use Wi-Fi extender (signal amplifier) : Choose a reliable brand amplifier and plug it into a socket that is not far from the dead zone. Let it "catch" the router's signal and amplify it and transmit it. It is a simple and economical way. However, if you use this, the internet speed may be a little slower. If the internet speed requirements are particularly high, you may have to think of other ways.

    3. The mesh networking system is a good choice : now many families have started using this, just use two or more mesh routing nodes to match them. They can "communicate" themselves and switch smoothly, allowing each room to enjoy a stable high-speed network with a large coverage area and good results.

    Third, let me tell you some questions that you may ask.

    Q: Is it really useful to place a high point on the router? Why

    Reduce Wi-Fi dead zones_Wi-Fi dead zone solution_Router location optimization

    Answer: Yes, because Wi-Fi signals are mainly sent horizontally. If they are placed higher, they will not be easily blocked by (such as tables and sofas), and the signal can be transmitted farther and more evenly, just like standing at a high place to throw things, which can be thrown farther and wider, right?

    Q: Which one is better than using multiple routers and mesh networking?

    Answer: Generally speaking, mesh networking is much better. If multiple routers are not the same system, the network may be disconnected when switching the network, and it is troublesome to set up; but mesh networking is a whole system, and the nodes cooperate well and can automatically switch to the best signal, which is very smooth to use!

    Fourth, there are some small details that need to be noted. If these details are done well, the effect of reducing dead zones can be better!

    1. You have to choose the right channel of the router : For example, in the unit building, many routers are squeezed together. If they all use one channel, you will not be able to squeeze out the head? Log in to the router settings page and see which channel is used less people. Just change to that channel, which can reduce a lot of interference.

    2. Upgrade the router : Sometimes the router firmware is old and the performance cannot be achieved. The manufacturer's background may optimize bugs and signal algorithms. Check it regularly – take a look when you have time, and try updating to the latest version? Maybe there will be surprises

    As for security and privacy, it is very important, but today we will mainly talk about reducing dead zones. Let’s talk about so much first. Just pay attention to setting complex passwords in daily life! Finally, I personally think that although mesh networking may cost a little more money at the beginning, it is the most worry-free and best-effect solution in the long run – really, whoever uses it knows the beauty!

  • Regarding the sleep nightmare prevention system we often call, it is actually something that many people nowadays, especially those brothers who often have terrible nightmares and can't sleep well at night, want to know. It is not the way to take medicine and get injections, but it is done quietly when you sleep through some smart devices and scientific methods, allowing you to do less or even less nightmares that scare you, thereby improving the quality of sleep

    1. The basic concept must be understood first : this system is generally composed of sleep monitoring equipment, such as bracelets or special mattress sensors, plus a small box for analysis and processing, that is, the host, and there is also something that can send weak intervention signals, such as a small module attached to the head of the bed. These three parts can only work together.

    2. Disassembly of key work steps : First, it is the monitoring stage all night, and the device will keep observing your brain waves – that is, sleep signs such as brain activity, heartbeat, breathing depth and body motion; then enter the data analysis link, and the host determines whether you are about to or are having a nightmare based on the built-in messy algorithm; finally, the most critical intervention is performed. When the system feels that the situation is wrong, it will use a very light vibration, or change the light, which is the color of the light in the surrounding environment, or even make a slight sound, which will "pull" you out of the nightmare but not wake you up completely, allowing you to continue sleeping! This step is very important!

    For example, sleep cycle monitoring does not wait until you have a complete nightmare before starting, but start working when you first enter the REM stage, which is the REM stage, and it looks a little bad! There is also body body movement detection. If you find that your hands and feet are moving in your sleep and your breathing is rapid, it will also trigger intervention. It is quite smart! Provide global procurement services for weak current intelligent products! Some advanced systems can also be connected to mobile APPs. When you wake up in the morning, you can see the sleep data report last night. When you may have nightmares risks, you can clearly mark them to facilitate communication with your doctor!

    FAQ time :

    Q: Is this thing so thorny when I sleep when I wear it? It's so uncomfortable

    Answer: Most of the newly released equipment are made of super soft silicone, which is warm in contact with the skin, and is designed to be very light and thin, like a small patch. Most people cannot feel it when they sleep, unless you are particularly sensitive, and you may have to adapt to it for one or two nights at the beginning.

    Q: Can children use this ystem? My child always wakes up from nightmares and crying!

    Answer: This depends on the product description! Most manufacturers recommend that children under the age of 12 should use it under the guidance of a doctor, because the child's brain is still developing and cannot interfere with sleep casually.

    Q: If I have nightmares all night long, will the system keep shaking and intervening, and what should I do if I can't sleep well?

    Answer: Don’t worry! Regular systems have an intelligent adjustment function, which will control the intensity and frequency of intervention, and try to solve nightmares while ensuring your overall sleep duration and sleep continuity, so that you will not feel more tired while trying to solve nightmares!

    1. Points to pay attention to when purchasing :

    If you have to pick a high sensor, it will be useless if the monitoring is inaccurate;

    Look at several interventions it supports, and multiple choices are always good;

    If the battery life is strong, at least you have to last the whole night and still have more surplus? Who can stand charging in the middle of the night?

    Where is the data stored? Is it safe? Do you understand? Personal privacy is important!

    2. Daily usage tips :

    Connect the device to the APP before going to bed, calibrate it, and don’t put it on just by yourself;

    Clean the contact parts of the equipment regularly, otherwise the dirt will accumulate and affect the monitoring effect;

    The effect may not be so amazing and immediate at the beginning. You have to persist in using it for a week or two to allow the system to adapt to your sleeping habits! Haste is not achieved

    Overall, for those who are deeply troubled by nightmares, they are really like a savior! It cannot guarantee 100% that you will never have nightmares again, but it can greatly reduce the number of nightmares and the severity of nightmares! But remember, it cannot completely replace psychotherapy. If the nightmare is caused by some serious psychological problems, such as PTSD post-traumatic stress disorder, you still have to see a professional psychologist! When purchasing related equipment, when it comes to global procurement of weak current intelligent products, you can consider solving the procurement problems as a whole. Maybe this website can help you very easily!

  • Regarding PSIM, which is the physical security information management system, many people may sound familiar to you, but they may be confused about what they are. Simply put, it is a system that connects all of those security equipment, such as surveillance cameras, access control controllers, alarm systems, etc. to a platform so that they can negotiate things without fighting! Nowadays, various units and buildings pay more and more attention to safety, and this thing seems to be more and more effective, which can save a lot of trouble…

    So what's the good thing about PSIM? There are so many benefits, but the most important thing is to collect a lot of scattered alarms and events together to deal with them! before? Monitoring is monitoring, access control is access control, and if something happens, people have to look at and check it one by one, and they are in a hurry. Now with PSIM, it can automatically bring together relevant information, not only tell you that something is wrong, but also roughly point out where it is, what the situation may be, and whether it is faster.

    To play PSIM, we can score a few steps and we can't eat it in one go:

    1. First take a look at your own stall : that is, first look at what security equipment you have, what brand and model, and whether you can speak to each other – this is a careless one, otherwise you can't connect to it even if you buy a PSIM, which is a waste of money, right? !

    2. Think about what you want to use it for : just want to simply look at the surveillance screen and collect alarms? Still want to make it more complicated, such as premonition through data analysis, or to automatically deal with some common small troubles? The uses are different, and the PSIM function selected is also different…

    3. Find a suitable cost-effective one and try it out : At the beginning, don’t pursue the big and complete one at once. You can first choose a few key places and key systems to try to connect to it to see if it is good or not, and if it is easy to use, it will not be too late to add the amount and expand the range if it is easy to use.

    When choosing PSIM, many people will be confused about one thing: Should they choose the standardized product that is ready-made for others? Or find someone to customize a complete fit in your own home situation? There are a lot of them here:

    Standardized products : The advantage is that it is generally cheaper, ready-made, and does not need to wait too long. Moreover, because there are many people using it, it is easy to find a place to repair it if there are any problems. But the disadvantage is that you may not be able to use some functions, and some functions you want do not have, so you have to worry about adapting to it yourself.

    Customized development : This is just the opposite. It can be done exactly as you think. You can basically make any functions you want, and it is easier to connect with all the strange old equipment you have. But? It's expensive! Moreover, the development time may be very long, and it may be a little more troublesome to maintain later, so you have to find someone to keep an eye on it.

    PSIM Physical Security Information Management System_PSIM (Physical Security Information Management)_PSIM Security Security Equipment Integration

    Then if you decide to use PSIM, what should you pay special attention to when implementing it? There are also some tips to refer to –

    • Data synchronization must be done quickly : the data formats of each subsystem are likely to be different. PSIM must be able to translate them into the same "words" and ensure that the data is accurate and timely when it is transmitted. You cannot wait for something big here and the data has not come yet.

    • The operation should be simpler and not too complicated : otherwise the staff will be busy and have to compete with such difficult systems every day. Not only will the error be made, but the efficiency will not be improved, right? It's easy to use and easy to get started than anything else!

    • The way to upgrade and expand capacity must be kept well : in the future, the company develops, the demand changes, or buys new equipment, can this PSIM easily add these new things instead of pushing the old ones back? This is very important! Provide global procurement services for weak current intelligent products!

    Finally, when using PSIM, you may encounter some questions. Here are two common sayings:

    Q: Our company is not big and has not many security equipment. Is it necessary to use PSIM?

    Answer: This depends on the person – if the equipment is really pitifully small, for example, there is only three or five cameras plus access control, then there may be no need to spend this money in vain, and it is okay to watch it honestly and manually; but if there are more than a dozen different brands and types of equipment, and there are more than one or two floors of the place, then using PSIM will definitely improve the work efficiency, which is a good thing in the long run!

    Q: Will PSIM be bought and installed?

    Answer: How can this thing be that simple? This thing is the same as the software we use. It also needs to be updated and maintained from time to time; and the operators also need to train them carefully to know what it can do and how it can be used. Otherwise, no matter how good the thing is, it will be like a pile of scrap iron! As you use it, you have to adjust the strategy according to the actual situation so that it can become more and more useful… I personally think that for those units that pursue efficient and standardized safety management, it is an unwrong direction to spend some time studying PSIM and be able to use it sooner or later!

  • Recently, we often hear people asking about the operation and use of Rooms and whether it works well. Indeed, this emerging guy is much more powerful than the lifeless guy in ordinary video conferences. In short, this Rooms can turn people far away into three-dimensional holographic images of the same size as a real person, and stand in front of your eyes, making you feel as if everyone is really sitting together for a meeting, even a small gesture and a small movement can be seen clearly and clearly! What is solved is that we don’t feel the meeting in another place, the communication is not smooth, and if we are anxious, we want to gesture and can’t understand the problem of not being able to see the other side, and provide global procurement services for weak current intelligent products!

    First of all, you have to know how this device was built? This thing is not just a ragged thing like a projector or a camera~

    1. The most core is the holographic display system. Some use super large transparent crystal curtains, and some are more advanced using fog imaging technology. Anyway, it is to let the eyes see the three-dimensional dummy – Oh no, it is a three-dimensional image! The clarity generally needs to reach 4K up, otherwise the face will be too much, so it will be more upset when you have a meeting, right?

    2. Then, there must be a 3D capture device, which is the dynamic capture system like shooting Hollywood blockbusters, but don’t worry, it’s not that expensive. It’s like several high-definition depths are placed in different directions, capturing every move of a person, even the way his eyes turn, and turning them into the 3D data in real time to pass it to the opposite side.

    3. Of course, ultra-high speed and low latency network environment is the top priority! Otherwise, the signal will be half a beat slower, and the person on the other side will open your mouth after you finish speaking. Wouldn't it become a sketch? Generally, it is recommended to enjoy the above uplink bandwidth at least, and the delay is best controlled within 20 milliseconds, milliseconds! It's not a second!

    When using it, there are a few tips to make the effect rise a lot higher! (I'll tell you secretly that many old users didn't know when they first started!)

    1. Lighting! light! light! What’s important to say… three times: Don’t smack the lights in the house in a mess! It is best to use that kind of soft top light, so that you don’t have a large window behind you, otherwise the figures you create are dark and terrifying like ghosts! Don't shine your eyes directly in front of you, as your face is pale and pale, and it is not good to look good.

    Evaluation of the effect of holographic meeting room_Holographic meeting rooms_Holographic meeting rooms usage tips

    2. The person attending the meeting has to stand in what they stipulate… called "capture area", usually draw a circle or frame on the ground. Don't go beyond that side. If you go beyond the image, you may be amputated – oh, the image of missing arms and legs is not complete!

    3. When you first use it, you can try it out in a short short session. Be familiar with how to adjust the sound size and image angle. Don’t just hold a long session for one or two hours. If it makes a joke like it’s not adjusted, it’s not worth it!

    Maybe you will ask, what is the difference between this thing and VR meetings? This is the difference, the boss goes:

    Rooms let you see the image directly with your naked eyes, and don’t wear heavy glasses. For those who don’t like wearing things, it is simply a blessing from heaven! During VR meetings, everyone needs to wear a headset. Not only do they feel dizzy and headache after wearing it for a long time, but they are also bored!

    That cost is a big difference! Although the holographic conference room is not cheap, VR needs to be equipped with professional equipment for everyone. The more people there are, the more cost-effective it is – no, it is the more expensive it is, and the long-term use is so high!

    Finally, let me say something about my personal thought. In the future, Rooms will definitely be the urgent need for those large multinational companies and money-burning technology companies! Not only can it save the travel expenses that are bubbling when flying back to Mars, but it can also make the cooperation and negotiations go smoothly! If you really want to do something, it is recommended to find some integrators with cases to ask, for example, who provides global procurement services for weak current intelligent products, and you can find accessories! Don’t be greedy for cheapness and buy a set of bargains. You can cry if you use the image to flash the black screen with two flashes!

  • Mars Life, which is the life-sustaining simulation system in Mars colonies, is a particularly important focus of attention in many aerospace research and related scientific explorations! After all, if there are really people in the future who want to live and live on Mars for a long time, then whether this life-supporting system can work normally and operate stably will have a big relationship! It is not just a matter of tricking it. It has to consider many factors, and it has to be simulated very realistically. Otherwise, it will be troublesome if there is a problem at that time!

    First of all, we have to figure out what this simulation system is: simply put, it uses various high-tech technical means, computer software, hardware equipment, etc. to imitate the extreme and harsh environmental conditions on Mars, such as low air pressure, high radiation, and extremely large temperature differences. Then, a similar experimental environment is built on the earth to test and verify the designed sub-systems for life maintenance, such as how to circulate air, how to deal with water, how to produce and supply food, and how to deal with waste, to see if they can allow astronauts or future colonists to have relatively safe basic survival guarantees in the Martian environment. This is probably what it means.

    Next, we have to talk about the key core module disassembly and good aspects, which are all the things that are really good.

    Super intelligent control subsystem for air quality: The main task of this subsystem is to ensure that the oxygen concentration in the simulated environment can be stable at a level suitable for human breathing, about 18% to 21%, which is the best range; then, the excess carbon dioxide exhaled by astronauts and other messy harmful gases, such as methane, are filtered and removed in time, or sometimes the carbon dioxide can be converted into useful oxygen through some chemical reactions or special equipment, so that the efficiency of oxygen utilization can be greatly improved! Moreover, it can also monitor the trace pollutants that may exist in the air in real time and dynamically, such as trace harmful gases that may be generated during operation of some equipment. Once it is detected that the standard exceeds the standard, it will automatically start the purification device. The reaction is so fast that it does not require anyone to keep staring at the manual operation. It is particularly convenient. Isn’t it great? Provide global procurement services for weak current intelligent products!

    Water circulation and super efficient regeneration subsystem: Everyone knows that on Mars, water resources are more precious than gold, and you must not waste a little at will! So this subsystem is particularly awesome. It can purify various wastewater generated in astronauts' lives, such as water used for washing, bath water, and even water that sounds dirty, and water collected by sweat evaporate. They are all purified step by step through a series of complex multi-layer purification processes such as physical filtration, chemical disinfection and biological treatment. The water after treatment is not only used to wash and flush the toilet again. What's more, after deep treatment, the water that meets the drinking standards can also be directly drunk by astronauts. In this way, the water can be continuously circulated, regenerated and utilized in that closed simulated environment, greatly reducing the dependence on water transport from the earth. This is simply too important and too problem-solving for long-term life on Mars!

    Food self-sufficiency and ecological collaborative production subsystem: Air and water alone are not enough to pass by, and people still have to eat to survive! So this subsystem is mainly used in the simulation greenhouse or special cultivation chamber, using advanced planting methods such as soilless cultivation technology, hydroponics and air cultivation to plant some vegetables and grain crops with short growth cycles and high nutritional value, such as lettuce, tomatoes, and some algae cultivation as supplements. Sometimes, they will try to breed a little high-protein organisms like insects to provide simulated astronauts with a more comprehensive and balanced nutrition source. The key is that this production system can also form a small ecological closed loop with the air quality control subsystem and water circulation subsystem mentioned above. Plant photosynthesis can absorb carbon dioxide and release oxygen. Plant growth requires water. Some plant waste generated can be processed and participated in other cycles. It is very good to cooperate and support each other!

    Fourth, it is the energy supply and intelligent management subsystem: this subsystem must ensure that all equipment in the entire simulated life support system can have a continuous, stable and endless power supply. Generally speaking, isn’t there a lot of solar energy on Mars? Therefore, it will simulate the use of large-area high-conversion efficiency solar panels to collect solar energy; if sometimes it is not cloudy for several consecutive days and sandstorms often appear to block the sun, it will also be equipped with some nuclear batteries or efficient energy storage batteries as backup energy sources to ensure that the power will not be interrupted suddenly, causing extremely serious consequences. Moreover, this energy management system is very intelligent. It can automatically and flexibly adjust the distribution of electricity according to the actual power demand in different time periods of each subsystem, so as to maximize the energy utilization efficiency!

    Super accurate monitoring and early warning subsystem for environmental parameters: This subsystem is equivalent to a loyal "sentinel", and is like a particularly strict "steward", where it is still motionless, constantly monitoring various key parameters in the simulated environment, such as the temperature I mentioned – the temperature difference between day and night is particularly large, the changes in humidity, air pressure, sometimes radiation intensity, and other things mentioned above, etc.; it can also monitor the operating status of each subsystem equipment. Once it is monitored that the parameter is about to exceed the safety range, or which device seems to have a minor failure, is not operating normally, and is not broken immediately, it will immediately send out a particularly obvious alarm signal to remind personnel in the simulated environment or scientific research teams monitoring outside to check the situation quickly and take corresponding measures in a timely and quickly manner to avoid the further expansion of minor problems and become irreversible disasters. This early warning mechanism is very good, which is particularly reassuring.

    Okay, now I will answer a few questions that you may be more concerned about. This will allow you to better understand the messy details of this Mars colony life-sustaining simulation system.

    Q: This simulation system is so powerful. Does it consume a lot of energy during its operation? Can it save energy and electricity

    Answer: In fact, when designing this issue of energy consumption, scientists and engineers had already thought of it, and gave priority to the particularly important principle of energy conservation and efficiency! They will choose low-power equipment and components such as LED lighting, and will also optimize the operating procedures of each subsystem so that they can reduce unnecessary energy waste as much as possible while meeting functional needs. As mentioned earlier, the energy management subsystem will intelligently distribute electricity and use electricity in the most needed places, so the overall energy utilization efficiency is relatively high, and the energy-saving effect is also good. It is definitely not the kind of system that will waste energy, and can be completely careless.

    In short, according to my superficial views and ideas, the continuous progress and development of life-sustaining simulation technology, and the various subsystems cooperate with each other to have a tacit understanding. This really lays a super solid and completely solid foundation for the future of mankind to successfully land and live on Mars for a long time. I believe that through the continuous hard work of scientists and experimental research in the future, this simulation system will definitely become more and more perfect, especially perfect, and more reliable. It is very worth looking forward to. Maybe in a few decades, we ordinary people will also see the successful establishment of the Mars colony on TV or on some image materials! Now that I think about it carefully, do you feel it’s very exciting! By that time, perhaps technology will develop to a new level that we dare not even imagine now!

  • In fact, many people have a lot of questions about the security protocol of the post-singularity era, just like me. After all, this thing sounds quite mysterious, right? Let’s talk about what is the post-singularity era. In layman’s terms, artificial intelligence and various high-tech developments have developed to a level that we cannot imagine now, and then the entire society and technology have undergone earth-shaking changes. This is probably what it means. The security agreement is the rules, methods, measures and other things formulated at that time to ensure that we ordinary people and the whole world will not have any major chaos or any serious security problems. It is very important!

    In the basic introduction to the security protocol of the Post-Singularity Age, there are several core concepts that you need to understand first, otherwise you will be even more incomprehensible. The first is the "super intelligent body control framework". This framework is not a random decision. It must clarify what the very, very smart agents that are countless times smarter than us humans can do and cannot do. Just like drawing a circle for it, it cannot be out of the circle! The second is the "nano-scale intervention and response mechanism". You think that the technology at that time must be so powerful that it can control very small things. What if something goes wrong with these small things? You must have a set of methods that can respond quickly and intervene accurately, and you cannot drag it out! Provide global procurement services for weak current intelligent products!

    Then, we have to break it up and talk about the key content modules. This part is practical information, so we have to listen carefully. Which modules are included? Don't worry, I'll say slowly:

    1. • Agent behavior prediction and constraint module: The function of this module is to guess what those super agents may do in advance, and then find ways to restrain them and prevent them from doing extraordinary things. For example, we have to predict whether their recent behavior will have any bad impact on the energy system and network system. Once we predict that there is a risk, we must start the constraint program immediately!

    2. • Cross-dimensional risk perception and early warning network: Don’t think that risks are only in the world we see now. At that time, there may be any cyberspace or even other dimensions that we cannot perceive. Therefore, this network is to be able to discover possible risks from all angles and places, and then issue a warning immediately to make everyone prepare!

    Post-Singularity Safety Protocols_Super Intelligent Control Framework_Post-Singularity Era Security Protocol

    3. • Dynamic hierarchical authority management system: Different agents and different responsible persons must not have the same power. This system must adjust at any time according to the actual situation and do what they have permission to do and what they do without permission. For example, some more dangerous operations can only allow the most core and reliable person or system to have this right!

    4. • Forced disconnection and reset function in emergency situations: In case, I mean in case! If there is a very urgent and out of control, this function must be performed. It can force the problem of the intelligent body or device to be disconnected from other parts. If it really doesn't work, it will be reset to let it return to its original safe state!

    5. • Automatic identification and maintenance unit for the bottom line of human core interests: No matter how developed the technology is, there is a bottom line that cannot be broken, that is, the core interests of our human beings, such as race continuation and basic survival rights. This unit is specifically focused on this. Whoever dares to touch this bottom line will automatically take measures to maintain it!

    Finally, add some details through Q&A so that everyone will know more clearly. Some people may ask, "Then are these security protocols unchanged once they are determined?" The answer is definitely not! Technology has been developing and dangers have been changing, so these protocols have to be updated frequently and adjusted frequently. Just like our mobile phone software updates, we must keep pace with the times and we must not go through it once and for all! Some people may ask, "Can ordinary people participate in the formulation or supervision of these security protocols?" I think that as technology is increasingly important to integrate into our lives, ordinary people should also have certain channels to understand and feedback. After all, safety is everyone's business, and we cannot rely solely on a few professionals, right? Of course, there must be reasonable mechanisms and methods in the process so that ordinary people can be heard.

    I personally think that although the post-singularity security protocol sounds far away from us, it doesn’t hurt to learn more about it. Moreover, the more technology develops, the more we should put safety first while pursuing progress, and take it step by step, and consider it thoroughly, so that we can truly welcome the future of high-tech with peace of mind!

  • , which is what we often call hyperspace bandwidth management. In fact, many people don’t understand it very much now, but it is particularly important, especially today when the Internet is being used more and more! Many people will ask what exactly is. Simply put, it is to control, allocate, optimize the bandwidth in the network transmission with super large space and ultra-long distances, so that the network can run smoother and not get stuck!

    You have to figure out this basic concept first, otherwise you won’t understand anything you say. It is not the same as ordinary bandwidth. It involves a wider range and a longer distance, and the amount of data transmitted may be extremely large! However, it is necessary to manage these messy bandwidth resources well, so that some places are not enough, and some places are wasted… It's like the water pipes in your home. There can't be any faucets that flow to the top, but some are dripping with water? That's so inconvenient, right?

    Next, let’s talk about this key content in pieces. This is practical information, you have to prick up your ears and listen carefully.

    1. Basic principles of resource allocation : This resource allocation is not just a casual snack! We have to consider who needs bandwidth more. For example, for some important service data transmission, we must give priority to ensuring its bandwidth and not let it get stuck; and there is also fairness. When everyone has no urgent matters, the bandwidth must be relatively fair (that means distribution) so that people don’t feel that it is unfair!

    2. Tips for real-time monitoring : Not only do you have to divide the bandwidth well, but you also have to stare at it anytime and anywhere! Let’s see how much bandwidth is used now, whether there is anyone secretly occupying too many resources, whether the network is smooth… all of these need to be monitored! You can use some special monitoring tools, or some management software itself has this function. Anyway, you have to find a way to know the real-time bandwidth situation! Just like a teacher staring at a student’s exam, you have to keep watching to know if anyone cheats, right

    3. Tips for optimizing transmission : If you find that the network is a bit stuck, it must be that the bandwidth is not used reasonably, so you have to find a way to optimize it! For example, you can compress the data to be transmitted to make the data smaller so that it will run faster; or change the transmission path and choose the fastest and least congested road! Also, arrange the things that are not in a hurry to transmit when the network is not so busy, so that you can avoid peaks! This is the same as choosing a road without traffic jams when you go out for travel, or traveling off-peak hours

    4. For now, dynamic adjustment ability is Super – super important! Because the network situation does not change from time to time, for example, a large wave of data suddenly pours in and needs to be transmitted. At this time, your management system must be smarter and automatically adjust the bandwidth, otherwise it will be a mess! Therefore, it is also necessary to choose a solution with dynamic adjustment function, otherwise it will be more troublesome and your hands will be terrible.

    Let’s answer a few questions you may ask below, just to add some details that you haven’t mentioned! I also hope it can help everyone manage this better!

    Q: When do you need to do it? Is this necessary for all networks

    A: Of course not! Generally speaking, if your network often needs to transmit particularly large files, or there are many people and equipment on the network, and the network always feels not enough, then you have to consider doing this! If only a few people go online and chat, then there may be no need to be such trouble! It depends on the actual situation! “Provide global procurement services for weak current intelligent products! ”

    Q: Which one is better, manually adjust or manage with intelligent system?

    A: To be honest, what era is now? It must be a good smart system! Manual adjustment is slow, and second, it is prone to errors, which is particularly expensive! The intelligent system can monitor and adjust automatically in real time, and is much more efficient! Unless your network is very simple, so simple that you can count how many devices you use the network with one hand, it may be okay to use manual, otherwise it is recommended to use smart ones!

    Personally, I think that although it sounds quite profound and complex, as long as you understand the basic concepts, master the tricks of reasonable allocation, real-time monitoring, optimized transmission, and dynamic adjustment – what are those tricks? Oh yes, it’s just the key points mentioned above – it’s not that difficult to understand and operate. The key is to choose the appropriate management methods and tools based on your actual network environment and needs, so that you can truly use it for you, rather than become a trouble for you! Take it seriously and the Internet will be much smoother and your mood will be better! How great!

  • About, which is the so-called civilization collapse backup, many people may actually sound quite mysterious! Simply put, if one day our current civilization disappears due to some great disaster, war or other majeure factors, it can save important things in our human civilization so that future people or our descendants can re-plug civilization and continue to develop. This sounds quite big, but it is really not a random thought. There are some people thinking about this.

    1. What content should I back up? This is too much! You can't stuff anything in it. First of all, basic knowledge , such as mathematical formulas and physical laws, must be included; then there are survival skills , how to hunt, how to plant crops, how to cure diseases and save people, and how to make clean water drinks, these are the foundations of life; and also history and culture , our civilization has developed for so long, and those important historical events, literary works, and artistic creations must be kept, otherwise how can future generations know what we were like before? By the way, there is science and technology . Although high-end and sophisticated things are probably not available, you must remember the basic technical principles, such as the simple principles of smelting metals and making machines.

    2. Where is the right place to hide? You have to pick this place! You can't just find a broken house and stuff it in. It must be particularly strong and can withstand ordinary disasters such as earthquakes, floods, and fires; the environment must be stable , it is too tide, things are easy to break, and the temperature is too high or low; it is best to be hidden and safe , so that people don’t easily find it and destroy it or lose it. Now some people think about digging big holes underground, such as abandoned mines, specially built underground fortresses, and some even want to throw them into space or get them on small islands to provide global procurement services for weak current intelligent products! If some advanced security equipment can be used in this hidden place, the preservation will be even greater

    There is something to talk about here, that is, how can this backup thing be understood and used? If you save a pile of oracle bone scripts or current computer codes and later generations get it like reading a book of heaven, it doesn’t mean it’s in vain! Therefore, how to make the information simple and clear so that people who are not experts can understand it is a big question. I have the idea to use the simplest pictures and symbols to express them, or to write explanations (Esperanto) that people from all over the world can understand.

    3. What to store? It’s not just a server to store it in a computer! The hard drive and USB drive of the computer may break down after decades of being left. You have to find something that can last for a long time. For example, carved on a stone? This can indeed be stored for a long time, but not only does the word "stone" slow, it can't save much; it is said that the coated CD or special film can be stored for hundreds or even thousands of years, but it has to be stored in a good environment; some people are studying the kind of synthetic DNA to store data, saying that using a little DNA can save old nose information, and in theory it can save millions of years. Even now, this technology is quite expensive and the operation is very troublesome~

    Q: Isn’t this thing spending money or worrying about nothing? A: It’s hard to say whether this is definitely true or not. You think, it is always good to have an extra layer of security, just like every household preparing a fire extinguisher when people catch fire. It is useless to put it there in normal times, and it will help you if you use it! Moreover, this civilization collapse backup plan can actually make people today more alert and care more about our current earth and the environment around us, and don’t want to just mess with some destructive things.

    Q: Can a country handle this? A: Personally, I feel overwhelmed! This is an old project. A country is afraid that it will not be able to withstand it if it spends money, people and energy. Moreover, the content of this backup should be the common treasure of all mankind, and it is not entirely the business of any country. Therefore, it is best for many countries to contribute money and work together and everyone will discuss it together.

    I thought about it myself and did this. Although it sounds a bit like the plot in a science fiction movie and it feels quite far away from us, I don’t think there is anything bad about this idea of preparing for the future. This is the same as when we live our daily lives, we save some rice and noodles at home to beware of bad times. If these backup things really have a day to take effect, then they will have accumulated great virtue! Even if that day is not the case, these attempts and efforts to preserve important knowledge are quite meaningful.

  • In the field of home safety protection, many friends will ask questions such as how to choose and how to use glass shatter sensors, which are the headaches. After all, who doesn’t have window glass yet, right? Glass Break is a small thing that can monitor the sound or vibration of glass when it breaks and then issue an alarm in time. It is also a very important part of our daily security configuration.

    The basic working principle of Glass Break is actually not complicated. Simply put, it is to "listen" or "feel" the special sounds and vibration frequency generated when the glass breaks through various small parts inside, such as microphones, vibration sensing chips, etc. However, different types of sensors may be a little different in their sensing methods

    1. Sound sensing type : This type of sensor mainly works by "listening to sound". It can capture high-frequency sound waves emitted by the moment the glass breaks; but be careful that if there is always particularly sharp noise in the surrounding environment, such as a child screaming, it may accidentally trigger it to alarm, causing a false alarm.

    2. Vibration sensing type : Vibration sensing type, as the name implies, will trigger an alarm when it feels vibration of the glass; generally speaking, it must be close to the surface of the glass when installed, so that the vibration signal can be captured more sensitively, otherwise it may not be easy to be used if the distance is too far.

    3. Sound vibration compound type : This combines the advantages of the previous two, which not only listens to the sound but also feels shocking. Relatively speaking, the false alarm rate will be lower, but the price may also be a little more expensive.

    When installing Glass Break, there are a few tips to pay special attention to. Otherwise, it may not work if installed, so it will be useless.

    If the installation height is as high as possible, it will be more appropriate to install it between 1.5 meters and 2.5 meters away from the glass; if it is too short, it may be easily blocked by things, and if it is too high, the sensing range will not be so accurate.

    The installation location is also a big question… It is best to face the direction of the glass, and not be blocked by heavy curtains, bookcases, and other big guys.

    Also, if there is a lot of glass in the same room, it is best to arrange the number of sensors reasonably according to the size and quantity of glass to ensure that each glass area can be monitored, and do not leave any blind spots to provide global procurement services for weak current intelligent products!

    Many friends may encounter some questions they don’t understand when using Glass Break. Here are some common ones!

    Q: The sensor always calls the police on its own. What's going on?

    Answer: This question may be that you install it in a place that will sway, such as when the window frame is loose, or there is continuous high decibel noise around it, such as when a high-power vacuum cleaner is working, it may cause it to falsely report! You can first check if the installation location is not correct, or adjust the sensitivity of the sensor to try it!

    Q: Can sensors accurately sense glass of different thicknesses?

    Answer: Generally speaking, most sensors can still sense ordinary single-layer glass, double-layer hollow glass, etc. for household use; but if it is a particularly thick or specially treated explosion-proof glass, you may need to choose a special model sensor with higher sensing sensitivity.

    Finally, my personal opinion is that it is still necessary to install Glass Break at home, after all, it can add more protection to our home safety! When you make a choice, you can comprehensively consider the type, sensitivity, and price of the sensor according to the actual situation in your home, and choose the product that suits your home most! When installing, it is best to read the product manual carefully or ask a professional installation master to help with the installation, so that it can work better and protect the safety of our home.

  • Hello everyone! At this point today, let’s talk about the Plate, which is what everyone often hears about license plate recognition . When identifying license plates, some people may think that they are far away from themselves, but they are not. When we usually drive into a community or shopping mall underground garage, we will encounter it working silently! Simply put, Plate is a kind of thing that allows the machine to automatically "see" the license plate! Then "read" the technique of the above number letters, does it sound OK?

    Provide global procurement services for weak current intelligent products!

    So what can this Plate be used for? There are many uses

    1. The most common thing is that the parking lot is charged. If you drive in, swipe it a little while. When you come out, you will automatically calculate the money and tell you.

    2. Then it’s a bit like the ETC channel on the highway, but the more complicated license plate recognition fee deduction is OK.

    3. There is also the entrance of the community. With Plate, a car that is not the owner cannot enter. It is safe!

    4. In terms of traffic management, speeding snapshots and other things are all used to record the license plate.

    5. There are also some special units and schools that use this to drive away those sales cars, which is quite convenient.

    Among them, the most core thing about Plate is of course the accuracy of the recognition! If you always admit the wrong license plate number, then won’t you be confused? Not only will it affect the speed of others' traffic, it may also charge the wrong money! Therefore, the current Plate technology is working hard to improve this accuracy. So what are the reasons that affect the accuracy rate

    When the light is particularly dark, or when the light is reflected under the sun, it may not be clear.

    If the license plate is a little dirty or is slightly bent, the Plate is also prone to "dreaming".

    If the car speed is too fast, the machine may have passed before it can react.

    Some license plates may have special signboards blocking a little alphanumeric, which is also troublesome.

    So what should you pay attention to when choosing a Plate device? You have to pick it carefully.

    Don’t worry about how powerful it is, actual testing is very important! Find cars with different light and angles to try Plate to see how accurate it is. (For example, if you get a dark car and try it in a place without street lights at night?)

    It’s the recognition speed. You can’t wait for a long time and it hasn’t figured it out yet, right? The faster the better

    Can this machine be worthy of the old equipment you have? For example, what system does your parking lot have? Don’t buy it and install it and can’t be connected. Isn’t it in vain?

    Do you think Plate is a lot of things?

    Next, I'll pick a few questions that everyone might ask, and answer them.

    Q: Can Plate be used on rainy or snowy days? I'm most afraid of this kind of weather!

    Answer: Most of the pretty good Plate equipment now have some waterproof and sun protection skills; but when it rainstorms or snowflakes are covered with cameras, it must be…the effect will definitely be a little bit worse. Unless it is a very awesome high-end device, you will usually be confused for a while.

    Q: Will Plate secretly save my license plate information? A little worried about privacy.

    Answer: This is a Plate equipment made by a regular manufacturer, which generally processes data in accordance with regulations; however, it depends on how the unit used it is set up, and it will generally not be stored for a long time? should!

    Q: How much does it cost to install a Plate in my community?

    Answer: This is really not accurate! Plate equipment is good and bad, expensive and cheap; it depends on how many doors are installed in your community, whether the construction is difficult, etc. It is best to find a few more companies to ask for the price comparison!

    The Plate technology has indeed brought a lot of convenience to our lives and has also made many places more effortless in managing. In the future, this technology will definitely improve and will become better and better! Do you have any questions about Plate? You can check the information yourself!
