Train axle box temperature monitoring method and device

Abstract

The embodiments of the invention provide a train axle box temperature monitoring method and device. The method includes the following steps that: a waveform jump index is calculated according to a target waveform curve, wherein the target waveform curve is the temperature waveform curve of a target axle box within a preset duration, and the waveform jump index is used to indicate the waveform jumpdegree of the target waveform curve; and a monitoring result is sent to a train control system according to the target waveform curve and the waveform jump index. According to the train axle box temperature monitoring method and device provided by the embodiments of the invention, a software algorithm is optimized, so that the software algorithm further has a function of identifying and judging an abnormal temperature curve. With the train axle box temperature monitoring method and device adopted, the problem of false alarms caused by the abnormal jump of axle box, gear box and motor bearingtemperature detection signals during the operation process of a D-series high-speed train can be solved; the probability of false alarms of temperature detection is decreased; and the operating efficiency of the D-series high-speed train can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit, and in particular to a method and device for monitoring the temperature of a train axle box. Background technique [0002] When the train is running, the axles and bearings rub against each other to generate heat. When there is a fault between the axle and the bearing, the friction force increases, the heat energy generated increases, and the temperature of the axle box also rises. When the temperature of the axle box exceeds a certain threshold, an axle burning accident will occur, and the train will burn Shaft faults directly threaten the safety of railway transportation, causing train delays in mild cases and derailment in severe cases. Therefore, it is very important to monitor the temperature of the train axle box. [0003] In the prior art, the method for monitoring the temperature of the train axle box mainly includes the following steps: first, the tempera...
