| Abstract: | The significance of communication among several CPUs and between CPU and intelligent display for combined vacuum magnetic switchgear is analyzed in this paper. And then, the theory of multi-CPU communication is introduced and the communication protocol is formulated. The practical scheme of communication system between PLC and microcontroller, PLC and PLC, touch panel and PLC is designed. Meanwhile, the method of implementation by use of hardware and software is proposed and the novel strategy to control multi-motors coordinately by means of real-time communication between single chip computer and PLC is developed. It has been proved by the field tests that the multi-CPU communication system is feasible in the scheme, exact in the data processing and quick in the data transmitting. |
