摘　　要：利用定向天线高增益、抗干扰能力强、通信距离远、方向性好和全向天线的覆盖范围广的优点,设计了结合两种天线的火车头车位监控系统。传感器节点以MSP430G2533单片机作为主控芯片,无线通信采用nRF905射频模块,GPS定位模块用于采集火车头的地理信息,并使用VB 6.0编写了监控软件,实现了对火车头车位的监控。测试结果表明,系统数据传输延迟小、丢包率低、运行稳定、测量准确,能够满足火车头车位监控的应用需求。Directional antenna has characteristics of high gain,strong anti-interference ability,long communication distance and directional,and omnidirectional antennas has advantage of a wide range of covering.The advantages of the two kinds of antennas is applied to locomotive parking monitoring system.MSP430G2533 is used as the processing core by the sensor nodes.RF905 RF module is used by the wireless communication.GPS module is used to collect the location information.Monitoring software is developed under VB 6.0 environment,and the locomotive parking monitoring is realized.Test results show that the data transmission delay of the system is small,and packet loss rate is low.The system runs stably,and measures accurately,which can meet the application requirements of locomotive parking monitoring.
