Abstract
For communication between the computer and field nodes,a data communication system based on the characteristics of PC104 bus architecture and the advantage of CAN bus was designed.FPGA was taken as the main control unit and CAN bus communication network composed of the C8051F040 MCU's internal CAN controller and the external CAN bus transceiver TJA1040 to test the data transmission performance,achieving the data's security,real-time,reliable transmission.Now,it has been applied to the test and measurement system in industrial control field.
