基于GPRS的接触网补偿装置远程监控系统设计

Design of catenary compensation device remote monitoring system based on GPRS

为准确、及时地发现铁路接触网补偿装置的故障,文中通过监测接触网环境温度及承力索、接触线的长度变化来判断接触网补偿装置是否有卡滞现象。该系统以C8051F930芯片作为系统的主控制器,以SIM900A无线传输模块作为无线传感网络的通信节点,各个节点之间以不同的时间间隔向服务器发送数据,结合GPRS无线通讯技术及Web互联网技术,将节点连接到远程服务器。实验结果表明,该系统性能稳定,检测精度高,满足相关设计要求。

In order to find out the fault of railway catenary compensation devices accurately and timely,this paper solves the problem by monitoring the ambient temperature and the length of the catenary. The system uses the C8051F930 chip as the main controller and uses the SIM900 A transmission module as a node of wireless communication sensor network. Each node sends data to the server at different time intervals,and combines with GPRS wireless communication technology and Internet Web technology to connect the nodes to the remote server. The experimental result shows that the system has stable performance and high detection precision,which meets the relevant design requirements.
