Abstract:

A fault detection system for train speed measuring and ranging equipment is designed in this paper. The system performs dynamic off-line off-line detection of wheel speed sensor and speed measuring and ranging processing unit, reproduces train running state and equipment failure condition. At the same time, it analyzes the test data of sensors and speed measuring and ranging processing units during the detection process, and selects speed, pulse value and power supply current. And other information for fault pattern recognition. The measurement results show that the fault diagnosis accuracy of the system is high, and the automatic detection of the service state parameters of the speed measuring and ranging equipment is realized.
