Abstract: A monitoring method is developed so that the temperature of truck brake shoe can be acquired in real time. To fine the maximum temperature position, the temperature displacement position of brake shoe is analyzed, which is also the best monitoring position. The monitoring system is built by sensor, data acquisition module and data processing module based on analysis of choice of sensor, design of software system and system implementation method. Comparison experimental test results show that the measurement error of the monitoring system is not more than 2.5%, and it is confirmed that the monitoring system is valid.
