Abstract: According to the problems in the supervisory system based on RS-485,this paper discusses how to use the microcontroller P87C591 and the technology of Field bus to realize the supervisory system based on CAN bus. The design involves RS-232-CAN protocol converter and dome controller about both hardware and software in detail. This paper also analyzes the characteristics of the design and indicates that it can be introduced into other
measuring and controlling field.
