CAN Bus in Distribution Control System Applied Research

摘要

The traditional distribution control system majority of uses RS-232 and RS-485 composes the collection to control the network. But its system itself failure detection is not convenient, the system expands not conveniently. This paper uses product USB-CAN and the CAN -RS232 and the CAN-RS485 of the zlgmcu Company to construction network architecture. Has established the movement in the PC machine control procedure. The programming realization carries on the data acquisition, the management to the distributional instrument, realized the different instrument data dynamic curve demonstration, realized ultra limits reports and realized real-time collection data save to database function. This collection and distribution control system can free add and remove nodes not affect the system work.
