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.

 

Key words: CAN field-bus; Intel 87C196KC; microprocessor protecting; monitoring
