基于CAN总线的变电站监控系统的设计与实现

基于CAN自定义协议Qucan_A,采用组态王开发了监控界面,实现了变电站与现场系统之间的数据通信,利用VB开发了主机驱动程序,提供了组态王与主机驱动程序的OPC接口,实现了变电站的保护、测量、采集、通讯、控制及运行管理、顺序事件记录,超限报警等。实践证明该系统运行状况良好,能保证变电站安全可靠运行。

Transformer Substation Monitoring System Based on CAN2.0B

The data communication based on the user layer protocol Qucan_A between transformer substation and the field sys tem has been accomplished,which the monitoring picture is developed by Kingview.The master driver program is designed by vb which provides the interface between Kingview and the driver programe.KingView Exchange information with VB by means of OPC interface,thus the monitoring system has been realized which have the functions of measuring,sampling, communication,control and running management,Order of events recorded,offgauge alarm,and etc.the system runs well in practice,Consequently,it further verifies the advancement and practicability of the transformer substation network.
