Design of A New Intelligent Controller with Communication for Low-Voltage Circuit Breaker Based on CANbus (Continued)

The development and design of a new intelligent controller with communication-capable for low-voltage circuit breaker based on CAN bus were introduced. The compositions of hardware and real time multi-task software, monitoring software of host computer and measuring and protecting algorithm were described in detail. The designs of 80C196KC, programmable device PSD934F2 and communication interface are expounded. The prototype of the controller was put into operation,the intelligent controller is connected with host computer to build a distributed monitoring system. The results of industrial practice show that this system can realize the functions such as measuring, protecting, monitoring and communication and has bright future of application.
