摘　　要：为监测动车组转向架关键部件温度,保障行车安全,利用动车组内Wi-Fi网络设计了一种无线温度监测系统.该监测系统由STM32单片机、Pt100不平衡电桥采样电路和RM-04Wi-Fi模块构成下位机采集系统,采用基于LabVIEW的PC机客户端结合Android系统的移动客户端APP组成上位机系统.经实验测试,该系统响应速度快,无线传输稳定,数据不丢帧,可达到±0.25℃的测量精度,监测数据可存储调用,满足动车组随车人员对转向架关键部件温度监测需求,对于保证动车组列车运行安全,积累行车数据具有重要意义.Aiming at monitoring the temperature of the key parts of EMU bogie and run safety, a wireless temperature monitoring system was designed by using Wi-Fi network within the EMU. The lower machine acquisi- tion system consists of STM32 microcontroller, Ptl00 unbalanced bridge sampling circuit and the RM-04 Wi-Fi module. The upper computer system is formed by PC client based on LabVIEW and mobile client based on Android system. Through experiment test, the system has quick response and stable wireless transmission. The frame is not lost and can achieve the accuracy of measurement to 0.25 ℃. The monitoring data can be stored and recalled, which meets the requirement with great significance to ensure the EMU train operation safety and traffic data accumulation.
