摘　　要：为了实现上位机与现场节点之间的通信,设计了基于PC104总线结构特点和CAN总线优点的数据通信系统。系统通过主控单元FPGA和由C8051F040单片机内部的CAN控制器和外部的CAN总线收发器TJA1040组成的CAN总线通信网络,对PC104-CAN总线的数据传输性能进行测试,实现了数据的安全、实时及可靠传输。目前已应用于工控现场使用的测试测量系统中。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.
