摘    要：介绍了一种基于CAN总线构成的高压开关柜智能保护与监测系统,以16位工业级单片机Intel 87C196KC为核心,应用现场总线和智能化技术将保护、测量、控制、远动和故障诊断等综合自动化功能就地分散到开关设备上.为了提高系统的实时性和可靠性,采用以双绞线为通信介质的CAN总线作为连接各开关柜的通信网络,构成全分布式结构.实际运行结果表明,该系统具有可靠性高、实时性好、抗干扰能力强、成本低等优点.

Abstract: This paper describes a microprocessor based protecting and monitoring system based on CAN field-bus for high voltage switchboard. The most important part of this system is a 16 bit single-ship micro-controller 87C196KC, and all the functions such as protecting, measuring, controlling, and fault diagnosis are enhanced to switch devices by the application of field-bus and intelligence technology. In order to increase the reliability and real-time character of the system,twisted-pair cable is used for communication between switchboards. The results of industrial practice show that this system has the advantage of high reliability, real time character, anti-jamming capacity and low cost.
