摘 要：为了解决基于DSP的真空开关真空度在线监测系统的数据传输问题，把变电站中每一个开关柜内的在线监测装置设计成单一CAN总线节点形式，在减少数据传输量的基础上采用局域网和CAN总线作为通讯途径，同时，给出了主要部分的具体实现方案。该方法解决了传输的可靠性问题，较好地解决了与上位工控机或个人PC的接口问题，实现了网络远程监控。

Abstract: In order to solve the data transfer problem of the online monitoring system based on DSP for vacuum degree of vacuum switches, the online monitoring system was designed in every switch cabinet into a single node on CANBus, in electric substation. After the data size reduced, the local area network (LAN) and CANBus were adopted to transfer the data, the primary parts implementation was also given. So the reliability problem in transmission solved, and easy to interface with epistemic industry computer or personal computer for system. At the same time, it can realize remote supervisory and controlling.
Key words: CAN bus; HPI interface; remote supervisory and controlling; ISA time sequence
