New regulations promote the vigorous development of green building materials

New regulations promote the vigorous development of green building materials

If a company has a vicious environmental incident and significant quality accident during the acquisition of green building materials, the competent department will order the green building material evaluation agency to cancel its green logo and may not apply again within two years and publish it through the information release platform to the public. This is a “hard clause” prescribed by the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology recently issued “Administrative Measures for the Evaluation of Green Building Materials Markers” (hereinafter referred to as the “Measures”). This means that China's building materials industry does not engage in "lifetime" for green standards.

Green building materials, also known as ecological building materials, environmental protection building materials, and healthy building materials, refer to healthy, environmentally friendly, and safe building materials, and are also known internationally as "healthy building materials" or "environmental building materials." Green building materials do not refer to individual building materials products, but rather to the evaluation of the “health, environmental protection, and safety” properties of building materials.

The green building materials evaluation mark stipulated in the Measures has three levels: one-star, two-star and three-star. The Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology are in charge of three-stars nationwide. The evaluation and logo management of green building materials; the provincial-level housing and urban-rural development, industry and information management departments are responsible for the management of one-star and two-star green building evaluation labels within the region. It is understood that the first batch of building materials that have been awarded the Green Standard will include energy-saving glass, ceramic thin brick, floor building materials, high-performance concrete, green chemical building materials, green wall materials, exterior wall insulation materials, water-saving sanitary ware, parts and components, mortar concrete And other major products. The green building materials are valid for 3 years and cannot be transferred, forged or counterfeited. The industry believes that the strict definition of the green standard can basically eliminate the “false green” commercial speculation and help promote the use of genuine green building materials in the market.

The current green building materials market is extremely unregulated. It is understood that some manufacturers often use the banner of “green”, “environmental protection” and “energy saving” to fool consumers. Moreover, many building materials products only have green building materials on the one hand, they declare that they are "green building materials." The "Measures" stipulates that in the future, all the "green building materials logos or certificates" produced by the companies themselves will be invalid, and consumers and the market may not agree.

The green building materials market will face great opportunities for development. At present, the country is making great efforts to develop green buildings, both in terms of policy and funding. Green building is inseparable from green building materials. And because of this, the certification of green building materials is extremely important. The new regulations will effectively regulate the industry and promote the vigorous development of green building materials.

Lightning protection of radio communication equipment

The natural weather phenomenon of thunder and lightning since ancient times has caused great impact on the development of human beings. If we do not pay attention to protection, it will cause serious damage to our lives and property. For the lightning protection of radio communication equipment, lightning protection design must be taken as an important task in engineering design. In this article, Zhengzhou Leidi Electronic Engineering Co., Ltd. technical personnel to analyze the radio's lightning protection related information.

The test of all single components in the secondary dispatch (current, voltage, time, differential, balance, negative sequence, distance, power direction, inverse time, frequency, synchronization, reclosing and other relays).

In general, there are four ways for buildings to avoid lightning strikes: 1) Diverting, ie, the earth where the charges in the thunderclouds are eased, thus avoiding direct lightning strikes or inducing lightning currents to flow through protected buildings or equipment. Things or equipment from lightning strikes. 2) Isolation, ie the isolation of lightning signals from the protected object to avoid lightning strikes. 3) Equivalence, that is, equal to the potential of the iron tower, work place, and public land of the building. 4) Dissipation, which releases the charge of the opposite charge and the charge in the thundercloud to neutralize it, thus preventing the formation of lightning. According to the above four lightning protection methods, the lightning protection measures of a radio communication project include the following methods.

1. Installation of Lightning Arrestors or Lightning Arresters Most of the lightning protection facilities for communication equipment are mainly equipped with lightning rods on communication towers. This method is economical and simple, but it must be installed in strict accordance with the following requirements.

a. The lightning rod should be installed a few meters above the tip of the antenna. There should be a certain gap between the lightning rod and the antenna to prevent the radiation pattern of the antenna from being damaged due to the existence of the lightning rod. The general practice is that the lightning rod becomes the main pole of the antenna tower, and the communication antenna is installed outside the outer edge of the lightning rod about 1.5 wavelengths.

b. The resistance requirement of the DC path of the lightning protection ground wire is sufficiently low, generally 10-50Ω. Due to the large lightning surge current, wide spectrum and short duration, it is required to have as small inductance as possible.

c. Flat wire or stranded wire cannot be used for the ground wire because the wire inductance is large, which is not conducive to the discharge of lightning current and is easily corroded. Use solid wires of 3 mm or more as much as possible, and it is the same metal material.

d. In order to increase the relief area of ​​the ground surface, multiple grounding bodies buried at certain intervals may be used and welded to each other. For example, 10 or so copper pipes are buried at an interval of 1 to 2 meters around the building and they are welded together.

Installing a lightning rod on a communications tower is economically simple, but it is difficult to be foolproof. For some important communications projects, consider installing a lightning protection device. The lightning protection device can be said to be one of the most advanced lightning protection devices in the world.

The key part of a radioactive lightning protection device is a radioactive source, which can continuously emit particles on its own and ionize the surrounding air to produce a large amount of electrons. These electrons are constantly accelerating under the action of the lightning electric field. They generate chain-linked multi-stage ionization or avalanche ionization, forming an electron flow proportional to the strength of the electric field. At this time, the ionization conduction from the radiation source to the thundercloud will never occur. Intermittently neutralize and release space charge, eliminate the existing low electric field, reduce the possible high electric field to a low electric field, thus effectively preventing the occurrence of lightning, and play a significant role in eliminating lightning. This kind of radioactive lightning protection device has a large protection area, its radius is about 260 meters, and its safety and reliability are not harmful to people. 2. In addition to installing lightning rods or lightning protection devices on communication towers, it is necessary to pay attention to eliminate lightning induced lightning. In lightning strikes, the usual practice is to install surge arresters in antenna systems.

When installing an arrester in an antenna system, pay attention to the following issues. One is that the grounding end of the arrester must be connected to the ground reliably. The grounding resistance must not exceed 5Ω, otherwise it will affect the lightning protection effect. The second reason is that there is a certain insertion loss in the arrester, which has a certain influence on the intensity of the antenna radiation signal. At the same time, attention must be paid to the change of the standing wave ratio. Generally, the standing wave ratio of the antenna system must be less than or equal to 1.5. The third is when the communication antenna is installed, the antenna struts and the tower are reliably connected, and the connection resistance is equal to 0Ω. The feeders should hang down from the inside of the tower and be fixed with copper wire and iron towers at intervals.

For important communication projects, besides installation of lightning arresters in antenna systems, attention must be paid to lightning protection of the power supply system. The general practice is to install lightning protection devices in transformers and power distribution rooms. All the above content is the experience summarized by experts of Zhengzhou Leidi Electronic Engineering Co., Ltd. If you need more information, please contact us directly.

Hardware locks need to pay attention to three points

Hardware locks need to pay attention to three points

Home renovation, high-quality hardware locks are related to furniture safety, and we must look at three points when purchasing.

First look at the lock implementation standards

Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. We can feel the good or bad of our locks. In general, the feeling of heavy locks, the quality is relatively high; the lock body can not be exposed, the exposed point is easy to hurt, in particular, should pay attention to the lock handle end of the lock, the lock tongue and the lock body four positions; lock spring good locks Flexible opening, high sensitivity and long service life. Locks also have a variety of styles, and must be consistent with the style of the interior doors.

Second, look at the lock material

The lock materials on the market are basically divided into stainless steel, copper and zinc alloys. Stainless steel has high strength, strong corrosion resistance and no discoloration. It is the best material for making locks; copper is more general, mechanical properties are superior, and the price is higher; locks are high-quality zinc alloys strong wear-resistant, strong corrosion resistance, and easy molding. Mostly used for mid-range locks.

Look at the lock surface treatment again (home improvement supervision)

Surface treatment is roughly divided into electroplating, spraying and coloring. The surface of the lock is used to form a layer of dense protective film on the surface of the product, which can play a role in anti-corrosion and anti-rust, making the lock more beautiful and durable. The dense protective film is also a measure of the quality of locks. Good quality locks are mostly plated. The coating is delicate, smooth, even and moderate, bright in color, free of bubbles, signs of rust and oxidation.

From a steam player - Gamepad purchase advice

Prior declaration

This article mainly focuses on the XBOX360 wireless controller, Steam controller, XBOX ONE S and other 300 price handle discussion.

I am aware of the elite handle, special + grab roll history 699, is 2-3 times the following handle.

And at the end, I tested several locally-cooperated on-screen games. Want to spend time with friends in the living room, the value of mutual harm in the room, you can see Oh ~

Then the body begins.

The first contact with the handle, childhood is playing bully, but since the home bought a computer, CS, World of Warcraft, Age of Empires and other games, has completely changed the way we play, mouse and keyboard games to play the game's convenience and accuracy has gradually replaced the handle. Until the PS3, the arrival of the xbox360 era, so many players want to try, play games on the PC to handle, is what kind of experience.

So 8 years ago, when I was a sophomore, I bought a North Pass handle with a pocket money of 100. I just came to the WIN7 era from the VISTA era and said that the system perfectly supports the handle. It was also the start of the steam road from then on, but there weren’t many games at the time. Pirates added genuine games to play a lot. Many games had to install xinput1 patches, and then they had to reset the keys in the game. It was very troublesome. So since then. Any friend who asked me to buy a handle, I strongly recommend not to buy this low price.


XBOX360 Wireless Controller Sea Amoy Microsoft Microsoft Xbox360 Wireless Red Box (support PC) .16 (about ¥290) Microsoft's official Xbox360 new version (with XBOXSLIM) wireless controller has two versions of the red box and green box, the handle is exactly the same, but the red box is more than a PC connected Receiver, can be used for PC games. The 2.4GHz wireless technology is used for the handle, and the effective distance is up to 30 feet (about 9 meters). Integrated XboxLive headset port for headset on the handle. Vibration Control can set the intensity to full speed, medium, low and off cloudshadow | Value 34 Comments 47 Favourites 9 Bellows Shopping To Buy

With more and more games in the steam, so in college, bought a XBOX360 wireless controller red box, boxed receiver, 250 or so.

The Philharmonic battery in my flash is used, so battery life is great.

The classic watermelon keys, blue, red, and green, support all games that use handles, and do not need to set keys to use directly in the game.


Both the trigger and the shock are in place, but it feels too strong to vibrate and can even hear the sound of a loose button when it is vibrating. The wireless distance is also very long and can be used throughout the room.

PS4 DualShock4 handle found Sony Sony (PS4 official accessories) PlayStation 4 new game controller black 299 yuan value of friends broke the original: 299 price is not bad, just need to buy. New PS4 controller. Experience is Low | Value 5 Comments 14 Favourites 7 To Buy View Details


After work, I was fortunate to have a PS4 handle, about 300 hands. The advantage is the use of Bluetooth links, to install a software simulation into the 360 ​​handle, some trouble. But now steam can use this handle directly, can use touchpad and gyroscope, but rarely use these two functions.

A light strip will show the status of the game, but also comes with a small speaker from time to time will make some sound, but these two features are not useful on the PC. I don't know if I didn't use a dedicated receiver (approximately 150 or so) or whether PC games weren't specifically designed for this.

The connection method can choose the USB connector, you can also use the Bluetooth function of the computer, Bluetooth is known to control the mobile game, and can also connect to my home Sony 49x8000c TV, the feeling is still quite interesting. However, I rarely play Android games, plus I am really not used to this handle, then sold. . However, if you have a PS4 and are accustomed to this handle, it is still quite recommended. Does not affect the use of habits, and save some money.


Steam handle

Haitao Valve Steam Controller Bluetooth Gamepad .99 + .44 Direct Mail China (about ¥259) US Amazon currently sells for .99, direct mail .44, reaches around 259 yuan, the price of this handle has been very strong since the end of the 15th listing, currently Haitao Compared to Taobao purchasing price has the advantage of 50 yuan or so, the price of self-transporting billing is more appropriate, users who often play Steam games can look at. Value Friends broke the original: SteamController computer game controller, price .99 (original price of soil bag mountain | Value 67 Comments 21 Collection 46 Bellows purchasing to buy

Last year, $ 35 + $ 5 direct mail, the first impression of hand, full of plastic feel, especially light. The feeling of grip is the largest one I have ever used. It feels great, my hands are small, and sometimes the keys are inconvenient.

Sent a mic-usb line, and a wireless receiver.

Go home and hurry to try it out. It's hard to tell. First of all, talk about the two most touched touchpads. The function on the left is the arrow keys and the pulley. On the right is the mouse. When it slides, there is vibration, but it is a very slight vibration. It feels wonderful and the touch is very good, but It's not the kind of touch the game wants.


In addition to the handles, these handles have conventional keys, and there are two separate keys behind them. Sometimes it is actually used, and shooting is more convenient.

The mouse position is also accurate, but it is useless. . . When playing the game, the default is no vibration, but do not know when to update the firmware, there is a "vibration simulation" function, sounds very dirty, but it does not feel at all stimulated. It is a very slight shock.

Let's talk about the support problem of the steam controller. Experiencing this handle on the steam can make you feel that the handle is not really bought. Perfectly supports steam games, and each game can be downloaded to other players for this game specifically set the key position. This is a good conscience. There are FPS mode, moba mode and many other gods to configure the program, the default rating, the number of points are clear at a glance.

However, the premise is that genuine games started on steam don't know about piracy. If you use Ubisoft's uplay to start, such as playing THE CREW, the keys will be chaotic and unable to drive normally. Similarly, some online games that support the handle, like Need for Speed ​​ol, are not supported. In fact, plainly, this handle is to simulate the keyboard. And compatible with other handles will have problems (finally will say).

The biggest function of this handle is when the wireless mouse is used, with the bluetooth mechanical keyboard and monitor bracket and lazy couch, Ge You lying, use this to control the computer to watch videos, brush microblogging, play with the mouse game is still very good . However, the function of this handle is not very stable without starting steam, and sometimes even fails.

XBOX ONE S tech Handyman Raiders

Find Microsoft Microsoft Xbox Handbags Special Forces Limited Edition 369 yuan value of friends broke the original: xboxones latest models, special agents, tech! Lowest price in history! Use the 399-90 volume, then participate in the white bar 618, 8 coins to exchange 200-25 volumes, 449-80-25, actual payment 334. This is an improvement over the xboxones, with improvements in Bluetooth infinity, non-slip material, and a better look. In addition, ones white version of the 399-80-Garnet Bird | Value 4 Comments 25 Collections 5 To Buy View Details


Finally talk about the highlight, xbox one handle. Updated with 3.5mm interface, with the receiver price of 300 or so, and then out of the xbox one S handle, directly with Bluetooth, the price is about 300, which makes people tangled, is to the former official receiver stability, or To the latter the better button adjustment and white models. Later, I still choose to buy the latter, after all, buy a new one does not buy the old, and sent a Bluetooth USB adapter when buying a Bluetooth mechanical keyboard. At the beginning of June, I broke the news and prepared to buy the white one s handle. But after one o'clock, I found that the latest extravagant cavalry actually reduced the price, and finally the actual payment 334 was bought.

domestic New low: Microsoft Microsoft Xbox One s Bluetooth wireless controller white 319 yuan package (399 yuan, coupons) comes with Bluetooth, eliminating the need for an adapter, XBOXONES handle price history low. Jingdong currently priced at 399 yuan, using Jingdong full 399 minus 80 yuan mouse and keyboard coupons, the final 319 yuan free shipping, XBOXONES handle price history low. Value Friends broke the original: good price in the near future, after using 399-80 volume, plus the full 199-20 exchange of white bars. While the Xbox Ones game console was released, Microsoft also brought a Garnet Bird | 130 Comments 174 Favourites 85 To buy see details


Because I haven't used the ONE S handle, but both come out of the same material. Take the tech handle and the ordinary one handle for comparison.

Tech's trigger is relatively soft, and there is no sound of Katika, the material of the entire handle made anti-skid treatment, feel very good.

The watermelon key has also become a kind of bright face, and the ABYX key uses a small dot to mark the color, making the overall senses not jump and maintaining military style. (However, looking for color may be a bit trickier when new players play qte.

The sensation of vibration is the most comfortable of the above handles, strong but not loose. Comes with a 3.5mm headphone jack, to use the USB cable to connect only sound, I heard when using the connector sound, but I usually use the speaker to play the game, that is, use the headset is also inserted in the computer, so it does not matter this feature.

Bluetooth function, can connect the computer and some Android phones, does not support a plus, hammer. But support Xiaomi, Meizu, Samsung, Sony mobile phones. Does not support Apple phones, and does not support their own wp system.

In addition, WIN10 comes with the UWP application, can update the firmware to the handle, but the identification seems to be a problem

Finally, talk about the speed of Bluetooth, I use a USB Bluetooth receiver, Bluetooth 3.0, I feel a slight delay, the more I feel more tolerated. The latest handle delay is the highest of these wireless controllers, slightly affecting the game operation.

However, I always doubt the reason for the low-غير مجاز مي باشدt Bluetooth receiver. To make this assessment objectively perfect, last week I decided to modify my ITX console, bought a MSI motherboard wireless card, 8260AC, and the latest Bluetooth 4.2. Take the motherboard M2 interface.

After 3 hours of disassembly, the radiator of the CPU was removed and the network card was installed. At last, it was turned on, tested several games, and found that the problem of high delay was solved perfectly.


to sum up:

If you are a student party or a player who can't bear to spend 300 dollars to buy a handle, the XBOX360 controller is your lowest choice, and it is less worry than all the third-party handles on the market. Remember. Recommended to buy wireless models, no restrictions, the game feels good.

If you are a normal player and want to use the handle to play some of the latest masterpieces to get the most out of your experience, then you will be deterred from the elite price. I recommend that you buy the XBOX ONE S controller, but it's best to buy a 4.0 Bluetooth receiver.

If you are a PS4 player, use the PS4 controller directly. Steam has perfectly supported the PS4 controller. It is very important to use habits.

If you are a steam brain residue, see the valve LOGO will be excited, and from the heart of a burning belief, then I recommend you buy a steam handle, lying on the sofa or bed, stroking the two touch version, imagine G fat that charity smile. But seriously, playing with this handle will have a great gaming experience on some games that don't have handles.

Finally, welcome to add my steam to play games with me.

====================================== Split Line========== ======================================

Last weekend, I invited my brother to play at my house and played dozens of games for two people with the same screen, and tested whether these handles are universal for local cooperation.

1.XBOX 360+XBOX one S handle

Can be recognized as the second player to join, perfectly compatible, the equivalent of the second handle. The keys are useless.

It is perfectly compatible with games such as "Battle Brick", "Breathing", "Dust 3", "Revolutionary Action" and so on.



2.xbox handle +steam handle

Can also be controlled, but some games have bugs, in the steam configuration, download a handle configuration made by other players on it. Not recommended for use. However, in the "Resident Evil 6" and other local online only a handle + a set of mouse and keyboard games. This combination of handles has a wonderful effect. In simple terms, the steam controller in some games, simulation is the mouse + keyboard and mouse.

3. Three handles together, XBOX 360 + XBOX ONE S + STEAM handle

Because few games support more than three people on the same screen, I spent a long time in my game library and tested the old driver of Hell, Castle Destroyer, Survival Guide 2, Sonic All-Star Racing, and Dungeon Keeper. This is a game with more than four people on the same screen.

There were some problems with the Sonic All-Star Racing Dungeon Keeper, which caused the steam controller to grab control of the buttons with one of the handles.


Finally recommend a software ~ sometimes used on!

Controller Companion on Steam This software can map any input from your PC directly to the Xbox 360/One controller, buttons, combo buttons, multiple mouse inputs, Windows system, direct rocker binding WDAS movement, camera shake, and more. Store.steampowered.com to see

Explosion-proof camera infrared light working principle and service life

At present, explosion-proof cameras can last as long as ten years in service life. Can infrared lamps be used for ten years? Today we come to understand the working principle and service life of the infrared lamp.

At present, there are three important types of infrared light production: First, halogen light, two, multi-chip LED, three, single-chip LED.


Explosion-proof camera infrared lamp working principle and service life Halogen lamp energy consumption is high, the heat is large, is the infrared lamp used in the traditional market, the application life is short, so it is difficult to suitable explosion-proof camera supporting applications.

There are also two kinds of multi-chip LEDs, one is containing 4 to 8 chips; the other is an array of light-emitting chips, containing 10 to 30 chips. Why do multiple chips? The potential reality is that the interval between IR lamps is not enough because the energy is not enough, more chips are gathered together, of course, the energy is large, so the irradiation interval is usually farther. If this can guarantee the acceptance rate of the infrared light, it is right, but under the premise that the receiving rate can not be guaranteed, more infrared light chips will only cause the operation temperature to be too high and affect the service life, and can not really improve the infrared light. Irradiation interval. In general, multi-chip infrared cameras are still based on ordinary halogen lamps in terms of performance, but multi-chip LEDs have no light-emitting focus because of their inherent structural defects. The light-emitting optical system is unreasonable and the useful light efficiency is also low. For example, an arrayed LED has a current of 1000 mA or more, and the root is only a penny coin size, and heat dissipation becomes a problem. And we all know that the technology, LED is the most afraid of high fever, ah, a high temperature is not bad it is difficult. At the same time, the production requirements of multi-chip LEDs are very strict. Each chip cannot have a slight difference in performance. Otherwise, if one chip is broken, the overall chip LED will be damaged. In general, the application of explosion-proof infrared cameras, the life of the existing multi-chip technology LED is far from enough.

Explosion-proof camera infrared light working principle and service life Single-chip LED production process is simple, quality is easy to guarantee, low heat, light emitting optical system is reasonable, is the ideal device for explosion-proof infrared camera infrared light, the actual application life of up to 100,000 hours the above. Therefore, natural technology is biased towards single chips. However, single-chip infrared lamps still have many constraining factors. For example, some LED chips have a very low level, and impurities exceed the standards; some production processes are closed, and there are leakage currents; some super power applications, rated at 20mA, are applied at more than 50mA; Some do not maintain the circuit, or the circuit design is not reasonable, these will lead to a single-chip LED infrared light quickly broken.

Explosion-proof camera infrared light working principle and service life To protect the life of infrared lamps, we must first use high-grade LED chips. High-grade chips have large power, good consistency, high luminous efficiency, and low calorific power. A high-grade LED is 10 times better than an ordinary LED, and the price is higher. Second, the optical system design must be reasonable, the light should be uniform, the utilization rate should be high, and the heat dissipation should be fast. Third, we must strictly control the operating voltage. The LED is very sensitive to voltage, and the LED die will burn off when the voltage is slightly higher. However, if the voltage is lower, the amount of light emission will be greatly reduced. It is best to match high-quality switching power supply. The AC input voltage can be better regulated from 170 volts to 270 volts to adapt to the harsh power supply environment. Fourth, the input power line is preferably made of anti-high/low temperature, ultra-soft, and anti-twist. There is a manufacturer of infrared light, the input power cord can be applied at a temperature of minus 60 degrees Celsius, 250 degrees above zero, and minus four or fifty degrees of cable is still soft and silky. This kind of product is trustworthy.

Therefore, there are also tips on the selection of infrared lamps for explosion-proof cameras. After understanding this knowledge, I believe that in the future selection of explosion-proof cameras, it will help you.

What are the characteristics of an outstanding parking management system?

At present, the parking lot management system has not yet appeared impressively impressive products on the market. This is partly due to the fact that China’s technology is not advanced enough compared to foreign countries, resulting in the incompleteness of the parking lot management system, difficulty in parking, and arbitrary charges. The problem can still not be solved, in the final analysis because the parking lot management system equipment is not good enough. What qualities should an outstanding car park management system have?

Appearance design: An intelligent parking system should not only be a manifestation of advanced technology, but also represent the level of the parking lot. Therefore, in addition to being easy to use, elegant and beautiful design is also very important. This is not only the market need to establish a brand identity, but also the user needs to create a parking environment with personal brand characteristics.

Automatic control: The parking system products we are looking for can be liberated from the cumbersome and complicated parking management and use advanced technologies to make the parking lots intelligent and unmanned.

System upgrade is convenient: Parking system belongs to electronic products, and an important feature of electronic products is upgrading. For users, how long does it take for hardware equipment to be used are not important, it is important to be able to keep the product constantly upgraded to meet people's parking needs.

Safety and security: The use of the parking lot system in the parking lot is to facilitate the management of the parking lot; the second is to ensure the safe parking of the user's vehicle. If it is not able to effectively protect the safety of the vehicle, no matter how advanced the equipment is, it will not be favored by the users.

Intelligent transportation is an inevitable trend for future development. Although the use of smart parking systems has gradually led to the standardization of parking management, these products still cannot meet the current parking needs of people. In the past two years, despite being robbed of the limelight by the license plate recognition system, the field of intelligent transportation is still very hot, and various smart parking system devices are emerging.

For more information on the functions of the parking management system, parking lot collection system, parking lot barrier, access gate system, cloud parking lot, etc., please contact Shenzhen Daoer Intelligent Control Technology Co., Ltd., China Smart Parking Cloud Platform No. 1 Shares, parking operator preferred partner.

Hardware enterprise implant marketing to identify key points

Hardware enterprise implant marketing to identify key points

In recent years, the implantable marketing model has penetrated All walks of life in a pervasive manner. The hardware industry has been “swallowed” by this trend. However, because of its industry-specific nature, it has not been able to match the speed of new products such as fast-moving consumer goods. However, the ever-changing market will eventually bring the hardware industry into a new era of marketing. Implantable marketing as a new type of advertising was born to the hardware industry.

Hardware cooperates with famous directors, business cards, and famous actors. If the cooperation is successful, the results obtained will naturally be a win-win situation. However, if the entry point selected by both parties is not appropriate, it may have a negative impact on one or both parties. Although hardware has chosen a film worthy of participation and investment, without careful analysis of the script and the plot of the film, it will accidentally become a negative “role” in the film. Even if the film can be successful, it cannot bring To the positive dissemination of products or brands, the negative influence of the brand will be infinitely increased due to the huge influence brought by the film. This is precisely the hidden risk of implantable marketing. Therefore, Jiuzheng Building Materials.com suggests that implantable marketing should make hardware brands or products related to programs as much as possible. The higher the degree of association, the stronger the concealment of ads, the higher the memory, and the arrival rate of advertisements. The higher. "Implantation" is by no means "placement." It means wisdom and planning, not simply putting in and collage, "setting up" is too extensive, and "planting" is an exquisite one.

The important prerequisite for implantable marketing quotes to be implanted appropriately is that they must not be disgusted by the audience and must be implanted in the implanted place. The hardware should not blindly request the frequency of occurrence, and should not be implanted for implantation. It's better to happen! Implantable marketing should pay attention to "degree". Although an irritating implantable advertisement was remembered by the audience, the actual effect was counter-productive. It was hoped to achieve the purpose of making the audience “remember, interested, and willing to buy.” Unfortunately, the audience was injected with “antibody” and let them A negative impression on the brand.

Implantable advertising marketing is used more and more widely in the home industry and is increasingly favored. However, hardware should also see implantable marketing as a fiery advertising method. While bringing new consumer groups, it also needs to pay attention to its potential risks, and truly become the “eyeball” that captures hardware consumers. Sharp weapon.

Problems to be aware of when maintaining small generators!

Problems to be aware of when maintaining small generators!

(1) TD series AC small-sized generators are negative ground. The polarity of the battery ground must be the same as that of the head. Otherwise, the batteries will discharge through the diodes and cause the diodes to burn immediately. When the battery is connected, the positive electrode is usually installed first. After installing the iron wire.

(2) When the small generator is running, do not use the spark test method to check whether the generator generates electricity, because it is easy to damage the diode.

(3) When the engine is not running, the ignition switch should be turned off. Otherwise, the battery current will periodically flow through the field winding and the regulator field coil and burn the coil.

(4) The wires between the small generator and the battery must be connected reliably. If they are suddenly disconnected, excessive voltage will be generated and the diodes will be easily damaged.

(5) When a small generator has a fault (no power generation or small charging current), it should be checked in time and it should not be continued for a long time, otherwise it will cause damage to other diodes or stator windings.

(6) When the six silicon diodes of the rectifier are connected to the stator windings, Megohmmeter (rocking table) or 220V AC power supply is absolutely prohibited to check the insulation of the generator, otherwise the breakdown of the diode is broken.

(7) The surface of the small generator should also be kept clean and the ventilation should be smooth; the transmission belt should be tight and elastic (use 98N force to press the belt, the deflection should be about 9~11mm.
