Vehicle axle temperature monitoring system and monitoring method

Abstract

The invention discloses a vehicle axle temperature monitoring system. The system comprises an axle temperature sensor, a receiver, a system host and a display. The axle temperature sensor is wirelessly connected with the receiver. The receiver and the display are connected with the system host through communication buses. The invention also provides a vehicle axle temperature monitoring method based on the vehicle axle temperature monitoring system. The axle temperature sensor monitors tire parameters in real time and sends the tire parameters to the receiver. The receiver analyzes the tire parameters and gives out corresponding signals to the system host according to analysis results. The system host transmits corresponding signals to the display for displaying. In the vehicle axle temperature monitoring system, the receiver is wirelessly connected with the axle temperature sensor, so flexibility of application of the axle temperature sensor is improved, and the effective receiving distance is far; the receiver and the display are connected with the system host through the communication buses and are free from limitations of installation position of the system host; and through wired communication, data is transmitted fast, stably and reliably.

Description

technical field [0001] The invention relates to the technical field of vehicle monitoring, in particular to a vehicle axle temperature monitoring system and a monitoring method. Background technique [0002] When the vehicle is running, the temperature of the vehicle's tire rotating shaft will continue to change. When the temperature is too high and the speed is too fast, the shaft will be locked, which will seriously affect the safety of railway transportation, and the safe operation of the vehicle cannot be guaranteed. [0003] Especially in the application of monorail trains, if the bearings of the running wheel and stabilizing wheel are stuck during operation, the bearing temperature will rise rapidly. The current monorail train running wheel and stabilizing wheel bearings do not have temperature monitoring devices, and there are occasional failures risk as a prerequisite. [0004] The same kind of axle temperature detectors are large in size, long in length, and use wi...

AI Technical Summary

Problems solved by technology

[0002] When the vehicle is running, the temperature of the rotating shaft of the vehicle tire will change continuously. When the temperature is too high and the speed is too fast, the shaft will be locked, seriously affecting the safety of railway transportation, and the safe operation of the vehicle cannot be guaranteed.

[0003] Especially in the application of monorail trains, if the bearings of the running wheel and stabilizing wheel are stuck during operation, the bearing temperature will rise rapidly. The current monorail train running wheel and stabilizing wheel bearings do not have temperature monitoring devices, and there are occasional failures risk as a premise

[0004] The same kind of axle temperature detectors are large in size, long in length, and use wired connections, which cannot meet the installation space requirements on the surface of the wheel bearing caps of various vehicles. If damage occurs, there is a risk of false alarms in the temperature monitoring system, which seriously affects the safe and reliable operation of the system.
