Coax Cable Used in RFID

Radio Frequency Identification (RFID) is an emerging automatic identification technology developed in the 1980s; RFID is a simple wireless system with only two basic coax cable. The system is used to control, detect, and track objects. The system consists of an interrogator (or reader) and many transponders (or tags). Transponder (predecessor of RFID): an electronic module that transmits information and reply information;

Due to the rapid development of flexible coaxial cable technology, the transponder has developed into RFID, which is also called a smart tag. RFID radio frequency identification is a non-contact automatic identification technology, which automatically recognizes the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient.

A complete RFID coax cable consists of a reader, an electronic tag, and an application software system. Its working principle is that the reader emits a specific frequency of radio wave energy to the electronic tag to drive the electronic tag circuit. When the internal data is sent out, the reader will receive and interpret the data in order and send it to the application program for corresponding processing.

Automatic vehicle identification technology that uses radio frequency identification technology and electronic toll collection. Install a base station at the highway toll booth, and install an RFID reader/writer card (radio frequency card) on each car. When the car passes through the toll station, the base station communicates with the radio frequency card, and automatically changes the amount of the radio frequency coax cable card according to the number of flexible coaxial cable the vehicle passes. It can realize true automatic charging, and the driver does not need to exchange cash, so it saves manpower and material resources. It can effectively prevent the corruption and fraud of some staff. In today's traffic jam in China, RF radio frequency identification technology will be the final development trend. This is the reason why radio frequency identification technology is difficult to popularize in China. RF radio frequency identification technology is generally applicable to open toll roads, that is, cars passing through toll booths are only charged according to the size of the vehicle, not according to the different entrance and exit fees. For closed toll roads, due to different entrances and exits, the tolls coax cable are different, so there is no way to use radio frequency identification technology, so it has certain limitations.

RFID is a flexible application technology that is easy to control, simple and practical, and especially suitable for automatic control. The identification work does not require manual intervention. It can support both read-only working mode and read-write working mode without contact or aiming; Can work freely in a variety of harsh environments: short-distance radio frequency products are not afraid of oil stains, dust pollution and other flexible coaxial cable, and can replace bar codes, such as tracking objects on the assembly line of a factory; long-distance radio frequency products are mostly used in traffic, and the identification distance can be Up to tens of meters, such as automatic toll collection or vehicle identification.
