摘　　要：在概述ZigBee通信协议的基础上,设计并实现了一种无线货运列车的轴温监测系统。该系统由机车节点和一系列车厢节点组成,车厢节点借助温度传感器采集轴温数据,机车节点通过无线模块发送控制命令控制车厢节点,接收车厢节点传来的轴温数据,利用液晶模块实时显示轴温数据,轴温异常时,语音报警,以此达到对列车轴温进行实时监控的目的。通过USB模块将轴温数据储存在U盘中,利用上位机软件对数据进行分析,了解车轴与轴承的使用状况,为货运列车检修提供参考依据,节省人力成本。Based on the summarization of ZigBee,a new wireless communication protocol,a wireless Hot Box Detection System was designed and implemented.This System was composed of locomotive node and a series tale-gate chain nodes.Tale-gate chain nodes acquired the data of hot box by temperature sensor.Locomotive node sent control command by wireless module and received the data of axle-temperature which was transmitted by tale-gate chain nodes.LCD module could display the data of hot box in real-time and the voice alarms when axle-temperature was abnormal.It could be monitored real-timely axle-temperature in freight train.PC software could analyze the data,which was stored in U disk by USB module,so it could be understood the use of axles and bearings,provided maintenance for the reference in freight train and saved on labor costs.
