Embodiment 2

[0057] Embodiment 2 has greater advantages with respect to embodiment 1. The arrangement of the single antennas in Embodiment 2 is: transmit -----receive -----transmit -----receive------, for microwave signals, this is also the arrangement, and The switching time of the transmitting antenna and the receiving antenna is very short, 40μS respectively. The transmitting antenna transmits a signal to activate the tag, and the receiving antenna immediately responds to the data reception, and even if the receiving data cannot be responded immediately, the adjacent transmitting antenna will be activated and continue to be activated. state, such a reciprocating cycle is equivalent to the train entering a large microwave magnetic field environment. Embodiment 1 is also arranged separately to enter a large microwave magnetic field environment, but the areas for transmitting and receiving signals are relatively concentrated, and the installation method of Embodiment 1 will have limitation...

Abstract

The invention discloses an antenna system capable of automatically identifying rail transit radio frequency identification tags. The antenna system comprises a ground antenna, wherein the ground antenna comprises a transmitting antenna array and a receiving antenna array which comprise a plurality of single antennas respectively and are arranged longitudinally along a rail. Separating type antenna arrays are utilized to receive and transmit microwave signals, and reading of data of the radio frequency identification tags in high-velocity motion is achieved. The antenna system can be applied to data identification of carriages, wheels, bogies and other vulnerable parts of high speed trains and ordinary trains.

Description

[technical field] [0001] The invention relates to rail traffic, in particular to an antenna system for automatic identification of rail traffic electronic tags. [Background technique] [0002] Vehicle number management is the basic work of railway shunting operations, formulation of scheduling plans, control of vehicles entering and leaving, and statistical management of vehicle occupancy time. The existing railway car number recognition process is: before the operator on duty, he must use the car number copied by the freight man at the station to formulate the shunting operation plan, and the copying and summary of the car number are all based on oral reading, notes and handwriting. Manually, the disadvantages are many errors and omissions, low efficiency and high labor intensity. Omissions and wrong copying of vehicle numbers have greatly increased the occupancy fee of trucks and vehicles. [0003] The Chinese invention application with the application number CN2009102145...
