Abstract: Countering the problems existing in the submersible motor, such as the complex condition of running, high malfunction ratio, many parameters influenced, This paper introduces the design of the distributed monitor system about the submersible motor based on CAN bus, and presents the hardware schematic circuits, software initial programs and communications flow of the intelligent monitor node. Practical using shows that this monitor system has the better control effect and is suitable for similar practical engineering.
Keywords: CAN bus; distributed system; intelligent node; P87C591
