As one of the key technologies of security and Internet of Things, RFID is increasingly rich in related products and system solutions, and the market application is gradually deepening, and the application field is expanding and expanding. With the development of intelligent transportation RFID technology has also ushered in new opportunities, stand out in many wireless connection communication and identification technology. While promoting intelligent transportation, RFID technology has also been able to develop applications more deeply. Let's take a look at the related content with the car electronics editor.

The rapid spread of RFID technology is inseparable from its many performance characteristics, such as rapid scanning, small size, diverse shapes, reusable, penetrating and barrier-free reading, large data memory capacity, high pollution resistance and durability. Such as the ability to adapt to the environment. RFID technology is increasingly applied to urban traffic management. An important carrier of this technology in the field of transportation is called automotive electronic identification, also known as electronic license plate. It is an ultra-high frequency radio frequency identification technology. And an electronic ID card formed by combining other related technologies.
Unknown car electronic identification system
The automobile electronic identification system communicates with the electronic license plate high-speed reading and writing device arranged on the urban road section by installing an RFID electronic tag for storing the vehicle identity data inside the front windshield of the vehicle, and can be used in the RFID electronic tag. The data is read and written to realize the identification and monitoring of the vehicle automatically, non-contact and without stopping. At the same time, combined with the original traffic information collection and traffic management platform, it can fully meet the requirements of the Ministry of Public Security "real-time monitoring, networked control, automatic alarm, rapid response, science, efficiency, information sharing", and achieve true digital, intelligent, Fine traffic management has fundamentally eliminated the “blind spot†of road traffic management in time and space, expanded the monitoring period and monitoring scope of traffic management, improved the intensity of urban traffic management, and provided the intelligent transportation system for smart cities. Key data services.
The popular application of automotive electronic identification system can accurately monitor urban traffic data in real time. The traffic data processed by big data can be used as data support for urban traffic congestion prediction and traffic planning. RFID-based automotive electronic identification urban traffic system can adapt to a variety of collection environments, can still accurately identify low-visibility, multi-lane vehicles at normal speed, improve the real-time and accuracy of urban traffic management, and make urban traffic more scientific And intelligent. The system can also monitor vehicle yellow-green label information and vehicle exhaust emissions, and play a major role in creating a green and environmentally friendly urban transportation environment. For example, in Chongqing and other places, vehicles equipped with electronic license plates will be automatically photographed to capture vehicle information when passing through the bayonet. The system will automatically screen yellow-label vehicles. Vehicles that violate the ban will be transferred to the penalty system. Nanjing is A displacement detection system has been formed to maximize environmental protection. In addition, the RFID electronic technology based on RFID technology has formed a complete security system for anti-cloning, anti-counterfeiting, anti-tampering and anti-illegal reading. It can be used for illegal decks such as fake decks, burglary vehicles, etc. And retrospective, regional traffic dynamic control and other vehicle-related public security management applications, improve vehicle screening capabilities, and accurately combat all types of illegal activities involving vehicles. RFID optimizes operation and management of the entire industry, can accurately check vehicle payment information, improve the collection rate of various vehicle-related fees, and also help to improve the efficiency of urban traffic. Travelers can accurately and accurately predict road congestion conditions and road conditions. Such information is reasonably arranged, and appropriate transportation is selected to promote the rational distribution of urban traffic flow. Take Beijing as an example. In recent years, Beijing's traffic management has not been able to curb traffic congestion from single-double to limited purchase. In the end, it can only achieve congestion charging through electronic identification, and it is low-carbon while relieving traffic pressure. It provides technical support for distinguishing the time limit of vehicles and the differential collection of sewage charges.
Why has the automobile electronic identification system not yet formed a national scale?
RFID technology has been used in more and more fields in recent years, and the penetration rate has been continuously promoted in intelligent transportation. However, until January 20 this year, Wuxi (National) Intelligent Transportation Industrial Park Enterprise in Binhu District ——The automotive electronic identification system led by the Ministry of Public Security’s research institute was officially opened in Wuxi. This is the first demonstration application city in China that uses automotive electronic identification and intelligent traffic management. Faced with the dilemma of thunder and heavy rain in this industry, we can't help but ask: Why has the auto electronic identification system not yet formed a national scale?
The biggest problem is the cost. First, each car must be equipped with a card of the size of a normal IC card printed with a serial number and a two-dimensional code, and attached to the upper end of the windshield in front of the car. Secondly, after the car is equipped with relevant equipment, it is necessary to equip the base stations in various blocks. This project will undoubtedly require huge manpower and material resources to be completed. Only in the first half of 2015, Wuxi City will complete the installation of 100,000 automotive electronic signs and the construction of 100 base stations, and carry out the management of truck passes. Demonstration applications such as traffic information collection, off-site traffic enforcement, parking access control, and bus signal priority control, comprehensively evaluate and evaluate the stability and reliability of automotive electronic identification, reading and writing equipment and related application systems. Finally, the follow-up maintenance, management, etc. of the system also requires the provision of professionals. Therefore, although it is a trend to popularize the system in the long run, it is difficult to spread rapidly across the country due to the relatively short-term investment.
We believe that the promotion of electronic police and bayonet systems based on video analysis and license plate recognition and the promotion of intelligent transportation solutions based on big data and deep learning can replace the electronic identification system of vehicles in traffic management. The application, which also affects the promotion of the technology.
What is an wall ap? In life, many times we will encounter a bad network situation, generally when the network is bad will affect everyone's mood, everyone likes the situation of network unobstructed, so will go to find a way to keep the network smooth, and wall ap can help you keep the network unobstructed, let's take a look.
1. wall ap
What is the wall ap is a lot of people want to know the problem, wall ap can let everyone's network has been smooth, wall ap is the most important part of the networking, wall ap and the socket at home, you can transmit signals through the wall ap, but want to really use the wall ap you need to install some network cables in each room in advance.
In other words, the wall ap can be directly called a Wireless Router, the wall ap can be used as the antenna of the router, if you put the wall ap in the room, then the signal in the room will be strengthened, but now people prefer the wireless router, so the wall ap also needs POE and AC two devices to assist.
2. AC
AC machine is the most common kind of router, it is very different from ordinary router, can not be used by simple insertion, but need to be set up several times to connect to the network, but also need to be combined with the wall ap to be better used, so the wall ap is very important. The combination of router and wall ap can enhance the network signal.
3. ap networking scheme
The ap networking scheme not only requires the wall ap, but also needs to add the control system, you can choose commercial, you can also choose home, for the network signal requirements of relatively high enterprises can choose commercial, before choosing the networking mode need to be carefully considered.
