板子无线DDN通信系统在道口监控设备上的应用

摘要

For the widespread railway-crossing monitoring equipment, a set of wireless DDN communication system is designed by using GPRS network resources, in order to meet the actual needs of railway-crossing remote monitoring and railway-crossing real-time alerts receiving from rail monitoring center. Rail way-crossing monitoring equipment is responsible for the security of railway-crossing, monitoring and recording its operation. And it will send stored data to data service center and related mobile phone through the connection between DTU terminal of DDN communication system and GPRS as well as Internet, so as to complete the collection and sending of the underlying data.%针对广泛分布的道口监控设备,利用GPRS网络资源,设计了一套无线DDN通信系统,以满足铁路道口监控中心对道口远程监控及实时接收道口警报的实际需求.道口监控设备负责道口安全防护及对道口作业进行监控和记录,通过DDN通信系统的DTU终端与GPRS及Internet 建立连接,将存储的数据发送到数据服务中心和用户手机,从而完成底层数据的采集与发送.
