Motor train unit axle temperature monitoring device with performance detection function

Abstract

A motor train unit axle temperature monitoring device with performance detection comprises a thermistor, a temperature display circuit, an electric heating plate, a comparison circuit and a prompt circuit. The thermistor, the temperature display circuit, the comparison circuit, the prompt circuit and the electric heating plate are installed in the element box and electrically connected, and the element box is installed at the outer side end of a bearing seat of a motor car driving shaft. The device is installed at the outer side end of a bearing seat of a plurality of driving shafts of the bullet train, the temperature display circuit and an existing axle temperature monitoring device are completely consistent in function, axle temperature data of the bullet train can be monitored in real time, and the detected data are transmitted to a control console in a cab of the bullet train in real time; technical personnel can detect the performance of a thermistor and the like according to needs during parking, when the resistance value of the thermistor has positive deviation or negative deviation due to various reasons, the technician can be prompted respectively, the technician can carry out overhaul and maintenance in time, and the service life of the technician is prolonged. And favorable technical support is provided for safe driving of the motor train unit.
