Problems solved by technology
[0004] At present, vehicles are basically not equipped with axle temperature monitoring equipment. Only a small number of subway vehicles are equipped with infrared auxiliary monitoring equipment at the entrance of the station. The infrared auxiliary equipment cannot be monitored in real time. The minimum transmission and power supply voltage is DC12V, etc., which is not easy to install on the car

Description
technical field [0001] The invention relates to the technical field of sensors, in particular to an axle temperature sensor circuit. Background technique [0002] When all vehicles are running, the temperature of the wheel rotation shaft will continue to change. When the speed is faster, the temperature will increase, and the wheel bearings will also wear out continuously. This will cause the shaft to lock, which will seriously affect the safety of railway and road transportation, and cannot be guaranteed. safe operation. [0003] During the operation of the wheel bearing, if the bearing is stuck, the temperature of the bearing will rise rapidly. If there is no axle temperature monitoring device to issue a temperature alarm, the driver will continue to drive, which poses a risk of serious failure. [0004] At present, vehicles are basically not equipped with axle temperature monitoring equipment. Only a small number of subway vehicles are equipped with infrared auxiliary mo...
