Problems solved by technology

Due to the limited axle load and space volume of the bogie of the EMU, the output power of the motor is greater, and the large operating current will increase the loss of the motor, resulting in an increase in the operating temperature of each component of the traction motor (sometimes even above 200 degrees Celsius) resulting in a hot spot temperature Frequent overrun
At the same time, the high-speed operation of the traction motor also makes the normal operating temperature of the bearings and other related components higher than that of traditional trains, and the loss during work is greater

Abstract

An axle temperature monitoring system fault detection method includes an axle temperature network model determination step: an axle temperature network model is established according to the position of each axle temperature sensor in an axle temperature monitoring system and axle temperature data monitored by the axle temperature sensors, and a current value of an index parameter of the axle temperature network model is calculated; a failure judgment step: a reference value of the index parameter is obtained, and whether the current value of the index parameter and the reference value are matched with each other; if mismatching occurs, it is determined that the axle temperature monitoring system has a failure. According to the method, fault detection is performed on the axle temperature monitoring system by adopting a method based on a complex network, and compared with the prior art, the method improves data quality, thereby reducing the calculation cost.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a fault detection method for an axle temperature monitoring system. Background technique [0002] In the field of rail transportation, with the rapid development of my country's high-speed railway, higher and higher requirements are put forward for the performance of trains. Due to the limited axle load and space volume of the bogie of the EMU, the output power of the motor is greater, and the large operating current will increase the loss of the motor, resulting in an increase in the operating temperature of each component of the traction motor (sometimes even above 200 degrees Celsius) resulting in a hot spot temperature Frequent overruns. At the same time, the high-speed operation of the traction motor also makes the normal operating temperature of bearings and other related components higher than that of traditional trains, and the loss during work is greater. Therefor...
