To avoid the defect of SCM,and meet the requirements of industrial stability and accurate data communication, a communication system based on FPGA is proposed in this paper. The hardware structure and design principle of the system are introduced. The analysis and design of the system were conducted according to the control flow and principle of FPGA. CAN bus data communication was realized by CAN controller SHA1000. The experimental results show that CAN communication sys-tem can meet the communication requirements,and has better performance and superiority than the MCU-based CAN communi-cation system.
