• Practical Guide

    Regarding (that is, what we often call crustal activity monitoring), it is not only for geology experts to care about, but also for ordinary people, we must know some tricks. After all, this is directly related to our safety, right? Simply put, it is to use various instruments and methods to stare at the "big stone" underground, how it moves, how much it moves, and how many Tectonic Activity Monitoring moves, and discover those changes that may cause trouble to life in advance. Provide global procurement services for weak current intelligent products!

    Which equipment can come in handy?

    1. Seismometer : It looks like a lying loudspeaker, with a slight "movement" underground. The tip of its pen can draw crooked lines on the paper. Professional people can tell if an earthquake is coming at a glance.

    2. GPS monitoring station : It is the same as the satellite we usually use for navigation, but it is measured much more accurate than navigation, reaching the centimeter level. Just stare at a certain point on the ground, see if it moves eastward or westward, how many fur it moves every year.

    3. Inclination meter : This thing is more amazing. It is specifically designed to see if the ground is like a seesaw. It can be displayed even if the angle changes slightly… the sensitivity is particularly high!

    4. Strain gauge : Buried underground or installed in a drilled deep hole, and feel whether the invisible "muscle" of the earth – the rock – is squeezed or stretched, just like doing an "electrocardiogram" or a stress test for the earth.

    What can ordinary people do?

    Even if we are not an expert, we can contribute some effort to our neighborhood, really!

    If there are mountains and steep slopes next to the place where you live, and after it rains heavily, check if there are new cracks on the slope and whether the stones have fallen, these may be the "restless" code below.

    If you have the conditions at home, watch TV and radio and pay more attention to the notifications sent by the local earthquake bureau and meteorological bureau. Learn earth (what?), which can help you establish a set of response procedures with your family. Use it to save yourself and help your family. You can use it to play a great value to ensure that everyone can survive safely and safely. Especially those who live in places like the beach should be more careful, and you have to see if the sea level is very abnormally high compared to usual, sometimes they can also give us some hints. Yes.

    What's the difference with the weather forecast?

    aspect
    Different objects Slow and powerful crust plates The storm and rain every day
    Features The forecast is extremely difficult (alas! There is no way…) High accuracy Frequency can only be seen clearly through long-term measurements Can be reported several times a day

    FAQ

    Q: How long will it take for a big event to happen after monitoring the shaking?

    "This is really not sure! Sometimes it's hard to sway for several days before it shakes a little, and sometimes it may come soon after it is monitored – for example, like the island in Japan is often like this…so you have to keep staring at it and dare not let go. Most of the time, the data is just used to slowly study Earth and conduct academic analysis reports to record these geological phenomena for inheritance and reference and future review. Only when special situations are rare data and phenomena may be considered as an emergency and then trigger alarm. Therefore, before we get accurate information, we must not panic and cause neighbors to follow the nervousness to create false panic to affect society. Do you understand this friend who asked the question…"

    I personally think that this technology really has a great effect on the safety of the people's lives and your living environment! Although the problem of "predicting earthquakes" worldwide has not been completely overcome… Maybe when the future technology continues to develop and improve, these will no longer be problems and obstacles that will hinder the pace of society… I really don't understand what I don't doubt or believe in. I ask professionals to help and ask questions and solve the problem. It is the best and most appropriate solution. No ~

  • In modern network transmission, Cat6 wiring is a keyword that is often mentioned by everyone. Many people consider using Cat6 cables when building or upgrading networks. So what is Cat6 wiring? Is it really much better than the old lines before.

    Basic introduction to Cat6: Cat6 is its full name 6, which is a twisted pair type network cable commonly used in Gigabit Ethernet. Compared with the old models and earlier Cat5 and Cat5e, the internal structure of the Cat6 cable can support higher data transmission, which is said to be sufficient. Its internal shielding design, which is what we often call shielded twisted pair (STP) or unshielded twisted pair (UTP), has a good effect on signal interference, and can make the signal more stable and more realistic when transmitted.

    The key content of Cat6 wiring disassembly module: 1. In terms of cable selection, you should carefully look at the wire diameter Cat6 Cabling. The standard Cat6 wire diameter is generally above 0.5mm. Those that are too thin may have poor quality and will affect the transmission effect. Also, choose wires produced by regular brands. Don’t buy three-no products from small workshops, otherwise problems will occur soon, which is troublesome… 2. In installation and construction, you must pay attention to the control of the bending radius and cannot be bent too hard. It is generally recommended not less than 4 times the diameter of the cable; during construction, the strength of pulling the cable is also given. It is too large to easily break the wire core and affect signal transmission, and provide global procurement services for weak current intelligent products! . 3. In terms of transmission performance, the frequency bandwidth it supports seems to be able to reach. When it is transmitted within 100 meters, it can basically achieve a stable rate. This is completely sufficient for the use of high bandwidth requirements in homes, such as watching ultra-high-definition movies online and playing large online games.

    Cat6 wiring practical Q&A supplement details: Q: Can Cat6 and Cat5e be distinguished by the naked eye? A: Generally speaking, the outer skin of the Cat6 cable will be clearly marked with the words "Cat6", and in the cross section, some Cat6 cables will have a cross skeleton in the middle, which is usually not available in Cat5e cables… Q: What should I pay special attention to when decorating a home pre-buried Cat6 cable? A: When pre-embedded, the cables in the pipe should not be too full, leaving a certain gap, which is convenient for future replacement; try to avoid walking the same pipe or bridge with strong power lines. It is not harmful to stay away from it to reduce interference.

    In short, in today's high data traffic and widespread environments that require high speed broadband connections, Cat6 cabling is indeed a good choice with its higher transmission rate and better anti-interference ability! It is very suitable for ordinary private homes to use the Internet and corporate offices on a daily basis; from a long-term perspective, it can better cope with the needs of future network upgrades, and it can be managed for a long time once installed! We can make standardization points in preparation, especially when wiring, to better utilize the performance of Cat6.

  • Plant is the smart thing that doesn’t require us to water flowers every day. Nowadays, many people who grow flowers at home, as well as friends who set up small gardens and small vegetable gardens, are very interested in this thing. After all, no one wants to make the flowers and plants wilt because they forgot to water it, right? It mainly uses some equipment to automatically water the plants according to the needs of the plants. Not only can it save trouble, but it can also make the plants grow better. Provide global procurement services for weak current intelligent products!

    First of all, we must understand what this plant is. To put it simply, it is to use machines and programs to replace us with manual watering. By combining sensors, controllers, and water pipes, they form a system. Then the system can judge by itself when to water and how much water to water. Isn’t it amazing?

    To get this plant, there are several key modules that need to be clarified:

    1. Sensor module: This is like the "eyes" and "hands" of the system, which can sense the dryness and wetness of the soil – this is very important, which is directly related to how much water is poured. Some can also sense the environmental factors such as air humidity, temperature, and light, and transmit this information to the controller.

    2. Controller module: This is the core brain! Receive the data from the sensor, and then decide whether to start the watering device based on the procedures we set in advance, such as what plant needs when and how much water. Nowadays, many controllers can be controlled using mobile APP. You can also see if the flowers are watered at home while lying outside, which is very convenient.

    3. Actuator module: The watering part after receiving the controller's instructions, such as solenoid valves, small water pumps, drippers, and spray heads, are all responsible for transporting water to the roots of the plant as required.

    4. Water supply module: This is the water source! It can be taken from the tap water at home, or it can be collected rainwater – environmentally friendly and save money! Just put a big bucket there, and it can also be other water storage equipment.

    Next, let me tell you some practical tips for doing this plant, all of which are from experience:

    When choosing a sensor, you must choose one with better quality and measurement, otherwise if the sensor is not accurate, the watering will definitely not be accurate, and the plants will suffer.

    When installing drippers or spray heads, adjust the position and water output according to different plants. Do not rinse a small succulent with a large water column, and the one will be gone! right

    When setting the program of the controller, you need to know more about the habits of the plants you raise. Some like wet and drink some water every day, while others are resistant to drought and not watering for ten days and half a month. They cannot be one-size-fits-all, and they all have the same watering time interval.

    Regularly check all parts of the entire system to see if there is any leakage in the water pipe and whether the wire connectors are loose. Don’t wait until the water leaks or the system is paralyzed before discovering it.

    Let’s talk about some questions you may ask:

    Q: Is this plant system expensive? Can you install it yourself?

    Answer: It’s hard to say that the price is hard to say. It depends on how large the scale you want to build and what level of equipment you use. It can be done with a simple amount of hundreds of dollars, and it is possible to get a more complicated amount of thousands or tens of thousands. Install it yourself. As long as it is not a particularly complex and large-scale system, buy some ready-made sets and follow the instructions to plan the watering automation step by step. It is not difficult for ordinary people to make it!

    Q: What to do if there is a power outage? Can the system still work?

    Answer: Most small systems in households cannot work if they are powered off, but now some advanced controllers have backup batteries that can last for a short time, or you can power the entire UPS, which can ensure basic operation even if the power is out.

    Finally, I personally think that this plant is indeed a good thing. It can greatly reduce the burden on growing flowers and plants, and also allow plants to receive more scientific care. It is worth learning about it and try out a set of conveniences brought by technology!

  • Regarding Age AI, it is actually a very advanced and intelligent computer technology to help take care of the lives of older people, making them live more convenient and safer! Nowadays, many children are busy with work and don’t have time to accompany the elderly at home every day, so this AI-assisted lifestyle has become a new choice for many people.

    1. Daily daily help module : This module has many practical small functions, such as the smart alarm clock will remind the elderly to take medicine and eat with a familiar voice. In addition, the lights in the house will automatically light up and dim according to the elderly's activity time – like when you wake up in the morning, you will slowly light up and wake up, and then slowly dim before going to bed at night to help you fall asleep. It's so considerate! In addition, for smart home control, the elderly can just say something, such as "turn on the light" or "turn on the TV", and those appliances can be moved by themselves without having to press the buttons

    2. Health monitoring and protection module : This is a very important part! It will use some small devices on its body, such as smart bracelets or watches, to keep an eye on the elderly’s heartbeat, blood pressure and other physical conditions all day long. If you find something wrong, you will immediately send a message to your family or the doctor in the community, which is in time! Also, the AI system can remember the elderly’s daily activity habits, such as how many steps they take every day, and if they suddenly become lazy and don’t like to move, they will also remind you if you are feeling unwell.

    Provide global procurement services for weak current intelligent products!

    3. Safety protection and protection module : This module is like asking an elderly person to stay away from sleep for 24 hours, always watching the situation at home. If the elderly accidentally fall down at home, the sensors on the ground can immediately feel it, and the AI system will immediately send an alarm and ask someone to help! There are also smart locks on windows and doors. If a stranger wants to come in, the system will immediately identify and call the police to ensure the safety of the elderly.

    1. Q: Will this AI system be difficult to learn? My elderly are not very good at using smartphones. Answer: Don't worry, this is good. The design takes into account the situation of the elderly. The operating interface is very simple, the characters are large and clear, and many functions do not need to be manually done. They are all automatically run. The elderly can basically use it without learning, which is convenient.

    2. Question: With this AI system, will the privacy of the elderly be leaked? Answer: Developers have long thought of this question. They have used powerful protection technology. All information about the elderly will be encrypted and saved. Only those authorized at home can see it. No one else can get it. It's safe.

    4. Emotional companion interaction module : Sometimes the elderly feel lonely at home alone, and this AI system can also talk with each other. It can tell jokes, sing, and can also accompany the elderly to recall old stories from the past, just like a talking friend, making the elderly less lonely! Moreover, it can also recommend some suitable music or movies based on the elderly's mood to make the elderly happy.

    In general, Age AI is indeed a good thing. It can bring a lot of convenience and safety to the elderly's lives, and it can also make children working outside more at ease. It is a good helper for the future elderly care life!

  • Bio-, which is the kind of sensor made of biosynthetic materials, has been very popular in many industries in recent years, and people have asked a lot, and it is used especially in places such as medical and environmental monitoring. Simply put, this kind of sensor combines biosynthetic materials, such as some artificially synthesized proteins, nucleic acid analogs, and other electronic components to detect various things – such as specific chemical substances and biological molecules, which are particularly effective!

    1. The response speed is very fast : it is several times faster than ordinary sensors, such as some metal sensors, and basically results can be produced in a few seconds. For situations where emergency testing is required, such as measuring the patient's blood sugar and lactic acid in the hospital, it is simply too useful!

    2. Super high sensitivity : Even if there are very few target substances, it can be accurately detected with only a little bit, and the error is particularly small. This is really helpful when looking for trace pollutants in environmental monitoring!

    3. The cost is relatively low : because many of the biosynthetic materials used can be produced on a large scale, unlike the rare materials used in some sensors, the price of the sensors made is reduced and small businesses can afford them.

    When using Bio-, there are several tips to remember, otherwise problems will occur:

    It is very important to choose the right material : different biosynthetic materials must be used for different detection objects. For example, if you detect heavy metal ions, you may need to use specific synthesizers; if you detect viruses, you may need to use artificial antibody analogs. You cannot choose randomly, otherwise the test will not be accurate!

    The ambient temperature must be controlled well : most of these sensors work best between 25℃ and 37℃. If the temperature is too high or too low, it will affect the activity of the biological material and lead to inaccurate detection results. Therefore, it is best to put a thermometer next to it when using it!

    Regular calibration must not be forgotten : Even the best sensor is, it will have deviations after using it for a long time. Therefore, every once in a while, about one or two weeks, you have to calibrate it with a standard solution to ensure that it is always accurate.

    Q: Bio-How long can it last

    Answer: Generally speaking, as long as it is properly stored, such as in a dry and light-proof place, seal it well when not in use, it can be used for 6 months to 1 year, which is much longer than some sensors! However, if it is often used in particularly harsh environments, such as places with strong acids and alkalis, the lifespan may be shorter. Be careful

    Q: Compared with traditional sensors, what are the advantages?

    Answer: In addition to what was mentioned earlier, it also has a great advantage, which is that its biocompatibility is particularly good ! When used in the human body, such as implantable sensors, the body will not easily repel and will not have any major side effects. This is too important in the medical field! Provide global procurement services for weak current intelligent products!

    1. Medical diagnosis : Doing portable testing equipment, such as blood glucose meter and cardiac marker detector, can be used by patients at home without having to go to the hospital all the time, it is so convenient!

    2. Environmental monitoring : Put it in water and air to monitor pollutants in real time, such as benzene and pesticide residues. You can call the police immediately if the standard exceeds the standard, especially in time!

    3. Food security inspection : Install a few food production lines to check whether the additives exceed the standard and whether they have deteriorated, so as to ensure the safety of what we eat!

    Bio- Although it is good, you still have to be careful when using and storing it – don't let it get damp! If the humidity is high, the biosynthetic materials inside are prone to deterioration; there is also a way to avoid oil stains, as oil stains will block the sensitive parts of the sensor and affect detection. As long as you pay attention to these, it is extremely high (accuracy) and can be used with confidence! Personally, I think this kind of sensor will definitely become more and more popular in the future, and use more places we can't imagine!

  • Hello everyone! Today, let’s talk about VPN. Many people may not know much about it, or want to know how to choose a useful VPN that suits them… In fact, VPN is a technical means that can help us perform various operations more securely and freely on the Internet! First of all, we have to figure out the most basic question, which is what is a VPN ? Simply put, it is like building a special, encrypted tunnel for us on a public, sometimes not so secure Internet, so that our data can be transmitted in this tunnel, making it difficult for others to peek or make trouble! This is of great effect for people who need to work with public Wi-Fi outside, or friends who want to read some foreign website content and avoid regional restrictions!

    So what are the main types of VPNs? There are quite a few types on the market, you have to sort it out carefully to understand and make it clear.

    1. According to the usage object and scope, there are generally two major categories: VPN for personal use and VPN for enterprise level. Personal use is usually simple, lightweight, and easy to use. It mainly meets our basic needs such as surfing the Internet, watching videos, and protecting our personal privacy. Enterprise-level VPNs are much more complex and have much more powerful functions. They need to consider many employees connecting at the same time, managing permissions in different departments, and how to connect with various internal systems of the enterprise, etc.!

    2. If VPN Solutions are divided according to technical principles, common ones include older ones like PPTP, but they are used less and less now, because everyone thinks that its security performance is not the top one; then L2TP/IPsec, which is much better than PPTP, and many devices also support it; and then, this is a very mainstream and popular one now. It is highly secure. Although the configuration is a little troublesome, it is particularly flexible and has strong adaptability. Of course, there are also new ones that are emerging, which are said to be very fast, and the code is simple and not easy to cause loopholes. It is a very potential young man!

    So what key points should we pay attention to when choosing a VPN? This is a big question, and you have to think it through step by step.

    First of all, the number of servers and the distribution location ! This is too important. There are many server nodes and a wide distribution of countries and regions. This means that we have more options to connect to, and it is not easy to cause a certain server to be particularly crowded and slow down. Moreover, if you want to connect to the network in which region, match the servers in the corresponding region, the success rate is much higher.

    The second is the connection speed ! This is directly related to our experience of surfing the Internet. If the speed is too slow, you can watch a video card for a long time and open a web page for a long time, then you will be very anxious and get angry. No matter how safe it is, it is useless. Isn’t it annoying? So you have to find VPN providers with sufficient bandwidth and good network optimization.

    And then there is the log policy ! This involves our privacy issues. You have to see whether the service provider will record our Internet behavior data, such as which websites you browse and when you connect. It is best to choose service providers who clearly promise that they are "no logs" or only record very little necessary information, and that this information will not be leaked to outsiders, so that they can feel at ease.

    There is also a limit on the number of connected devices at the same time ! Now everyone has many electronic devices, including mobile phones, computers, tablets, and smart TVs at home. If one account can only connect to one device, it will be inconvenient. So we have to see if it can connect to several devices at the same time. If it is enough, we can use it ourselves.

    When encountering problems during the selection process, provide global procurement services for weak current intelligent products!

    Let’s talk about the tips when using a VPN to make it better and avoid traps

    To regularly check and update VPN client software! Because software developers will frequently release updates in order to deal with the emerging new security threats and fix some minor bugs. If not updated for a long time, there may be some potential risks or functional shortcomings, which will affect the effectiveness and safety of use. So develop the good habit of taking a regular look and fashioning if you update.

    Try not to use VPN to do some illegal and irregular things! Although VPNs give us a certain amount of network freedom, this freedom is based on compliance with laws and regulations and cannot be used indiscriminately. We must be a good citizen who abides by law. Otherwise, if there is a problem, it will be more than worth the loss!

    If you are using a VPN solution in China, you must obtain and use it through formal and legal channels. Never trust those VPN software with unknown sources and are known as "free and super powerful". Many times, those may contain virus Trojans, or they will secretly collect our personal information, which is too dangerous!

    Finally, let’s answer a few small questions about VPN that you may often ask, so that you can understand more comprehensively.

    Q: Can a free VPN be used? Is it much different from paid ones?

    Answer: Some free VPNs can be used temporarily to meet some very basic and simple needs. However, they usually have many restrictions, such as the small number of servers, the speed is particularly slow, the lot of ads is annoying to watch, and most importantly, how can it make money with a free VPN service? This makes people worry about whether it will make plans on our privacy data, and the security risks are relatively higher. Paid VPNs are generally much better in terms of server resources, connection speed, security, and customer service. They get what you pay for. For users with long-term and stable needs, it is recommended to carefully consider the payment option!

    Q: Will using a VPN slow down my network?

    Answer: This is possible, but how much slower it down? It depends on many factors. For example, if the server you are connected to is far away from your actual location, if it is particularly far away, the loss and delay on the data transmission route will definitely be large; there is also the current load of the server, if there are too many people connected, the pressure will be high, and the speed will naturally be slow; and the VPN protocol itself has different impacts on speed, as mentioned above, it usually performs better than other old protocols; of course, it is okay if the original network bandwidth you use is enough! In most cases, if you choose a high-quality VPN service provider and a suitable server, the slowdown will be within an acceptable range and will not affect normal use too much.

    My personal opinion is that choosing a suitable VPN can indeed bring a lot of convenience and security to our online life, but you must spend time understanding and comparing more, choose according to your actual needs, and obtain and use it through formal channels, so that you can truly use it with worry and confidence!

  • 10,000-Year, is the kind of equipment maintenance instructions that can manage for ten thousand years. Have you heard of it? Generally speaking, the instructions we usually see can only be kept for three or five years or ten or eight years at most. Have you ever seen such an outrageous but seemingly necessary? After all, some particularly important things that are related to the inheritance of human civilization or nuclear waste storage facilities, etc., must be considered ten thousand years later, otherwise no one will know what to do if there is a problem! So, the core goal of these 10,000-Year is to make people in ten thousand years later understand and use these maintenance knowledge even if their language changes or civilization is broken. Isn’t it super challenging?

    First of all, we have to figure out what is difficult to write such a ten thousand-year instruction manual? It’s not like just asking someone to copy the ordinary manual!

    1. The materials have to be beaten up : Think about it, for ten thousand years, what paper or plastic should not turn into slag? Therefore, it is necessary to use materials that can resist physical wear, chemical corrosion, and even nuclear radiation, such as particularly hard stones, corrosion-resistant metal sheets, or some specially treated synthetic materials… This is very critical! We have to think about whether people can discover these materials and interpret the information above ten thousand years later.

    2. Not understanding is a big problem – you have to talk about the contradiction of understanding : language will definitely change! Today's Chinese and English are likely to be like in ten thousand years. So what language is it written in? Do you want to make some pictograms? Or use any common symbols in the universe – such as mathematical formulas – to express basic concepts? This is all knowledge! Also, the cultural background is different. The icons we take for granted now may not be meaningless at that time. Provide global procurement services for weak current intelligent products! This sentence doesn't take ten thousand years to maintain, just put it this way.

    3. Let’s talk about the disassembly of key modules and what should I include when writing this ten thousand years of manual? You can't write it blindly!

    The first piece, the core information – must include : What is this maintained thing? What is the name (but this name may be the least useless 10,000-Year Maintenance Manuals, who will remember it for ten thousand years), what it looks like (it may be more reliable to match a super simple picture), what it is used for, why it is important, and what serious consequences will be if it is broken. These must be explained in the simplest and least dependent on specific cultures.

    Second, the maintenance steps must be more concrete and you cannot go around the corners of your friends : This part is the most troublesome, but it is also the most important!

    1. When does a wave of inspection need to be checked – Regular inspection cycles and items: is it once a year? Once in ten years? Or is it a check every 100 years? Where to check? What tools do you use (Tools are also a headache, and you can’t come with a tool manufacturing manual that you can understand for ten thousand years!)? When checking, you should pay attention to whether there are cracks, leaks, or strange sounds or smells in the place – these phenomena that can be felt by sensory may be the most lasting.

    For example, "When you see cracks on this part that exceed the width of your finger, you should prepare to repair it; or if you get close to it, you can smell a stinking smell like a bad egg, that's not right." Isn't this more reliable than writing "when the pressure sensor reads more than XMPa"? After all, it’s hard to say whether the sensor is still there for ten thousand years.

    2. Get minor problems by yourself – Simple fault judgment and troubleshooting: If you find that a small part is loose, how to tighten it (with a wrench? with a stone? You have to make it clear); if a certain place is blocked, how to clear it.

    3. If it really doesn't work, you have to ask for help – what to do in an emergency: In what circumstances must you stop using this thing immediately? When encountering very, very dangerous situations, which direction should you run and what to do – this is very important!

    In the Q&A format, some details need to be thought of :

    Q: Should this manual be updated continuously? It’s been ten thousand years, and there must be new discoveries in the middle!

    Answer: In theory, it should be updated, but how to update, who will update, and how to save the updated version with the original version are a bunch of new questions. Perhaps it can be designed as modular, with the core part engraved, and additional instructions can be attached next to it with relatively less durable but convenient to replace materials?

    Q: What if people understand the problem in ten thousand years later, what if they treat the maintenance manual as a manual of "how to destroy it"?

    Answer: This…this is indeed a big problem! Therefore, when expressing the meaning of warnings, dangers, and prohibiting operations, you must be very cautious and cautious! Use more warning symbols that can be understood across cultures, such as skulls (warning danger), large crosses (forbidden), or patterns of running away by one person (run quickly!).

    I personally think that doing this 10,000-Year is not so technical, but rather a philosophical and ethical work. What information does our generation want to leave for their descendants in ten thousand years? What attitude should we use to face the far and unimaginable future? This is worth pondering and it is much more interesting than simply writing a manual. Although it is difficult to achieve it!

  • , which is what we often call the performance verification protocol. This thing is used in many places where product testing and engineering acceptance is used. Regarding its performance verification protocols, how to do it? Maybe many people, like me, are all lawsuits! Simply put, it is a set of rules and steps that are set in advance and written in black and white to check whether something is in compliance with its performance or not. Don't think it's as simple as just a look.

    1. Basic component modules of the protocol : First of all, there must be _test, which means what you want to test, and you must clearly define the basic situations of model and specifications; then, what do you use as a standard to judge whether it is good or not, and there must be a basis for it? For example, a certain standard stipulated by the state, a certain specification agreed by the industry, etc.; and the other is _test. Which performance points are measured, whether they are speed, accuracy, or stability, must be clearly listed one by one; finally, to put it bluntly, where is the passing line, how much is reached, how much is reached, it is not possible to calculate how much is reached, it must be as clear as black and white!

    Provide global procurement services for weak current intelligent products!

    2. Disassembly of the verification process steps : The first step is to prepare the temperature and humidity, power supply voltage, and whether there is any interference around. These will affect the results. How to test if you don’t do it well? Then, follow the protocol and operate step by step, such as how long to warm up on the computer, how to set parameters, and how many times the data is sampled, you cannot change it at will; after the measurement is completed, you can record the original data, and this data cannot be filled in blindly, it must be measured in real way; finally, compare the data and see if it is qualified, and give a conclusion – the whole process must be the same as the process, and no step can be missing!

    3. Common precautions and guide to avoid pits : Remember, the agreement itself must be first by all! Everyone has to nod and agree with the buyer, seller, or tester, otherwise everyone will talk about their own words at that time, so why don’t they make a big noise? Also, the instruments and equipment used for testing must be checked in advance. If the test is not within the validity period, the accuracy is inaccurate. If the instrument is not accurate, what is the use of the measured results! – By the way, you have to write the steps when writing them. Don’t write some ambiguous words. If you don’t know how to do it after reading them, then it will be useless!

    Q: After the agreement is written, can it be modified casually?

    A: You can change it, but you must not change it secretly by yourself! All relevant parties must discuss it together, write a change record, and everyone signs and confirms it. Otherwise, if there is a problem in the future, who will admit it? You can't be careless!

    Q: Compared with _test plan_, are they the same?

    A: Of course it’s different! Test plan is more inclined to the general direction and framework of the entire test, such as why you need to test, who will test, and time schedule; and it focuses more on the details of how to do it, what to test, and how to judge the passing of the test, and the focus is completely different – don't mess it up!

    I personally think that if you do this carefully, it will be no harm in controlling the product quality or the successful acceptance of the project. Taking the time to do this is much better than reworking if there is a problem in the future!

  • In today's rapidly developing modern society, when people go out to stay in hotels, they are not just as simple as paying attention to whether the room is clean and whether the bed is comfortable. The requirements for the various audio and video entertainment equipment in the hotel – which we often call Hotel AV – are getting higher and higher! After all, no one wants to watch movies and listen to music comfortably in a hotel room just like at home. If there is a meeting, the projection and audio equipment in the conference room must be powerful, otherwise it will affect the situation more! Therefore, doing a good job in Hotel AV is important to improving the overall level of the hotel and the satisfaction of customers!

    So, then again, what is Hotel AV? To put it simply, it is the general term for all the solutions related to audio and video equipment. It not only includes the TV and audio in the room, but also the projectors, large screens, microphones in the conference room, and even the sound reinforcement systems that play music and broadcast notifications in the hotel lobby. They are all included in this category.

    If you want to build a hotel's AV system, it is not possible to just buy equipment and piece it together. You have to pay attention to some aspects:

    1. Device compatibility : This is a big problem! If the compatibility of different brands and models of equipment is not good, it will always cause bugs when used, and there will be no sound for a while, and the screen will be stuck at a moment. The guests are worried about using it, and the hotel will be extremely troublesome to maintain! Therefore, when choosing equipment, you must do your homework in advance and ask whether the manufacturer can "get along" well.

    2. Convenience of operation : Whether it is the hotel staff or the hotel guests, they all hope that the simpler the operation of these AV devices, the better. If it is too complicated and you don’t know how to turn on it for a long time, then people will definitely not be happy. It’s best to have a one-click control system, or use a mobile phone to scan a code to control it easily, which is much more convenient.

    3. High-definition picture quality and sound quality : What era is now? You can’t see human faces clearly when watching TV. Listening to music is like a mosquito, that’s definitely not possible! Therefore, the high-definition display screen and the sound equipment Hotel AV Solutions with clear sound quality and no noise are the basic conditions that must be guaranteed.

    4. System stability : This is so important! Imagine that the guest was watching happily, and there was no signal when the meeting was held; when the meeting was at a critical moment, the projection suddenly fell off, which would be so embarrassing and affect the reputation of the hotel! Therefore, the equipment is of excellent quality and the system must be maintained regularly.

    There are some practical tips to help when actually installing and using Hotel AV:

    For AV equipment in the guest room, power management should be done well. For example, the TV will automatically turn off after the guest does not pull out the jam. This will not only save energy, but also extend the service life of the equipment. It will kill two birds with one stone.

    For the AV system in the conference room, it is best to preset several common modes in advance, such as meeting mode, speech mode, and video mode. When switching, you can call the mode directly, so you don’t have to adjust it every time!

    Some people may ask, is expensive equipment necessarily good? Actually, it may not be exactly like this! Although you get what you pay for, the quality of equipment that is too cheap may not be guaranteed, but you don’t have to pursue those top-notch and scaryly expensive equipment. The key is to choose the most cost-effective equipment based on the hotel's own positioning and budget, which is the smartest way to do it! Someone asked, will everything be fine if the system is installed? Of course not! Subsequent maintenance and updates are also very critical. The equipment will age after being used for a long time, and the software also needs to be updated and upgraded to meet new needs. Therefore, keep in touch with reliable maintenance agencies or manufacturers and conduct regular inspections and maintenance to ensure that the system is always easy to use.

    Finally, I personally think that if you want to truly do a good job in Hotel AV, you must understand the actual needs of customers, choose appropriate equipment and solutions, and pay attention to subsequent services and maintenance, so that the hotel can stand out in the fierce competition and win more love and praise from customers!

  • When mentioned what is it? Is it inconvenient to install it? I guess many old comrades who are engaged in computer room wiring and weak current projects will scratch their heads? To put it bluntly, it is actually in the factory in advance, and according to the designed specifications and lengths, the cables, connectors, and various module components are all made into standardized "small units" or "modules"! Alas, it’s a bit like building blocks – when you arrive at the construction site, you don’t have to cut, strip, or hit crystal heads as before. Just click these prefabricated modules, click ~ Yes, just plug and click, and you can use it by connecting them! Compared with traditional on-site manual wiring, this method is simply too much trouble and can save a lot of effort! Provide global procurement services for weak current intelligent products!

    When using it in practice, what are the "very good" aspects? For example:

    1. The installation speed is not ordinary fast : in the past, a few people used to build a line of tens of thousands of meters, which might have to be done for ten days and half a month; with this prefabricated modular, the same work would probably be able to handle most of the work in three to five days, which would be greatly advanced!

    2. The probability of problems can be reduced a lot : when the factory is produced, the environment is controllable, the tools are professional, and the personnel skills are stable. Unlike on-site wiring, sometimes a little mistake can be made when your hands shake, resulting in poor contact? The modules made by the factory are relatively high in quality!

    3. You can take up a little less space : because the factory has designed the best path and bundling method, the cables can be neatly managed, unlike on site where there are piles and messy, which looks refreshing~

    4. In the future, it will become convenient if you want to modify or add some equipment : if you want to increase the number of point ports, just unplug the old one and plug in the new one, without having to do a big move to reorganize the line.

    So in which scenarios are they mainly used? Generally, large data centers, financial institutions computer rooms with high network stability requirements, and some corporate core computer rooms that are not convenient for constant shutdown to make trouble are used more often. After all, these places have high requirements for wiring timeliness and reliability! Then if it is an ordinary home decoration or a small office and a small network, is it impossible to use it at all? It can't be said so absolutely… It can be used even in small places, but it may not seem that good-for-money from the perspective of cost or necessity! Maybe using traditional wiring is enough.

    The most common questions I hear everyone ask… are just a few:

    Is this something particularly expensive? When I bought it first. It is certain to be more expensive than bulk wires, but you think, from the money saved by installation labor and the hidden benefits brought by less trouble in the later maintenance, maybe saves money in the long run? So it must be considered a comprehensive cost.

    Will there be compatibility issues during use, such as it does not match my original/device? Before you buy this, you have to confirm the matter with the supplier one by one, including the messy and key information such as the interface type and signal transmission rate, but you can't be careless! It is best to take the sample to do a small test in advance so you can feel at ease.

    The length of this cable is fixed. What should I do if my actual site is a bit different from the pre-designed Prefabricated modular cabling systems? It doesn’t matter, manufacturers generally not only provide several standard-length modules. Also, they will customize and produce some special-length modules according to the specific sizes of the customer site, so don’t worry about not having to choose! It is the customized delivery period, need…it may be a little longer.

    At the end of the day, I personally think that this is definitely an important direction for future cabling technology! Especially for large institutions or growth enterprises that pursue high efficiency, high quality, high stability, and are not inferior to the initial investment cost and hope to save worry and effort in the later maintenance, this is simply a "treasure" choice, and it is worth understanding and considering it! Moreover, after using it, the computer room looks clean and tidy. Will it be much more convenient to check problems in the future?
