Aimming at the safety problem of heavy commercial vehicles running on long downgrades, a temperature wireless monitoring system for brake drum based on NewMsg_RF2401 is presented in this paper. An overall design program of the temperature monitoring system for brake drum is given as well. The hardware and software including the minimum system circuit of Freescale S12 MCU, the signal acquisition module, the wireless transceiver module and the MCGS human-computer interaction intelligent instrument are designed and implemented. Finally, the loading road experiment for the monitoring system is provided. The results prove that the temperature monitoring system for heavy commercial vehicle brake drum could monitor the temperature in real time, achieve intelligentization, visualization, security and stability, and improve the safety of running on long downgrades for heavy commercial vehicles.
