Problems solved by technology

However, the wheel runs in a rotating motion, the microwave environment is harsh, the metal shielding is serious, and the signal is not easy to read
[0010] As a result, the existing technical solutions of the automatic railway number identification system cannot obtain the information of the wheels of the rail vehicle during the high-speed operation of the vehicle.

Embodiment 2

[0062] Embodiment 2 has greater advantages with respect to embodiment 1. The arrangement of the single antenna in embodiment 2 is: transmit----receive----transmit----receive-------, for microwave signals, this arrangement is also the same, 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 limitations...

Abstract

The invention discloses a wheel tracking system for rail vehicles. The wheel tracking system comprises a control system, a ground identification system and a plurality of radio frequency identification tags arranged on wheels of the rail vehicles, wherein the ground identification system comprises a ground identification device and a ground antenna array connected with the ground identification device connected with the control system. Data of the radio frequency identification tags on the running wheels of the rail vehicles can be acquired by means of the ground identification device and the ground antenna array of the ground identification system, real-time data statistics and automatic collection of data including wheel working states and the like can be achieved, production cost is reduced effectively, safety production efficiency is increased, and the reliable statistic basis is provided for safe and stable running of the wheels.

Description

[technical field] [0001] The invention relates to rail vehicle management, in particular to a rail vehicle wheel tracking system. [Background technique] [0002] Wheel tracking is one of the routine standards for routine inspection of trains. In order to ensure the safe operation of railways, train wheels need to be routinely inspected every 3 months. The time for routine inspections of high-speed rail and bullet trains is shorter because the wheels are steel and the tracks It is also made of steel. When the train runs on the track, the friction of the wheels, from a microscopic point of view, the wear of the wheels is not a regular circular wear, but an irregular elliptical wear. This irregular wear, beyond a certain level, is An eccentric circle, the center of gravity is not at the center of the circle, and the rotational vibration increases. In order to avoid this situation, routine inspection and timely return to the factory for repair are required, and the working life ...
