基于ZigBee的货运列车轴温监测系统设计与实现

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,杌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.

Design and implementation of Hot Box Detection System for freight train based on ZigBee

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.
