Auto vehicle identification device based on radio frequency identification technology

Abstract

The invention provides an auto vehicle identification device based on radio frequency identification technology. The auto vehicle identification device comprises a radio frequency module and a decoding module, wherein the radio frequency module comprises a radio frequency emission circuit and a radio frequency receiving circuit; the radio frequency emission circuit is responded to a power amplifier startup signal sent from a vehicle number host to generate a radio frequency signal, and the frequency signal is output via an antenna; the radio frequency receiving circuit receives a label modulating and returning signal obtained by coupling label information into a radio frequency signal, and the label modulating and returning signal is output after the label modulating and returning signal is divided into two paths of label baseband signals; and the decoding module receives the two paths of label baseband signals and uploads the paths of label baseband signals after the label baseband signals are subjected to analysis processing. On the basis of modular design thought, the auto vehicle identification device can be conveniently expensively applied, and the auto vehicle identification device can be assorted with other pieces of vehicle number host equipment to be applied to various occasions.

Description

technical field [0001] The invention relates to the field of train automation management, in particular to a railway car number reading device based on radio frequency identification technology used in a railway train number identification system. Background technique [0002] The railway department has launched the construction of the automatic identification system for railway car numbers. This system can collect train numbers, car numbers and arrival and departure information in a timely and accurate manner, and can speed up the realization of track management of freight cars, locomotives, trains, and meet the needs of modern railway transportation management systems. The demand for basic information such as trains and vehicles will eventually realize the modernization, networking and resource sharing of transportation operation management, so that railway transportation can realize modern management as soon as possible. [0003] Among the existing products, a complete tr...
