A data collection and control system based on CAN bus is introduced in this article. Using the PC,AT89C51 single chip, SJA100CAN controller, 82C250 CAN transceiver and MAX232, the design of the hardware circuit and software of the system is realized. This system is of flexibility ,convenience ,good reliability ,and high communication ratio. Moreover ,it has the great capacities of resisting disturbance and communication error detection. So it is a good resolution scheme for the automated data acquisition and control system.
