摘　　要：介绍了CAN总线在变电站综合自动化系统中的应用模式 ,设计了一套基于CAN总线通信的低压综合保护测控装置。装置中的保护插件采用了双CPU结构 ,其中监控CPU采用了PHILIPS公司生产的内嵌有CAN控制器的微处理器芯片P5 1XA -C3,再配以适当的接口器件 ,装置便可以方便地与采用CAN总线技术的监控网连接。软件基于CAN总线通信部分 ,采用了P5 1XA汇编语言编程 ,简单高效。最后具体给出了保护插件上P5 1XAThe pattern of CAN network applied to substation integrated automation system is given and the integrated digital protection device based on CAN field bus is introduced. The protection element in the device adopts double CPUs, of which the monitoring CPU is the microprocessor P51XA-C3 with the build in CAN controller produced by PHILIPS, so the device can easily join the monitoring network of CAN field bus with necessary interfaces. The software for CAN communication is designed in P51XA assembly language. The specific hardware and software design of the CAN controller in microprocessor P51XA-C3 on the protection board is provided.
