摘　　要：为使CAN总线网络通信更加便捷,提高CAN总线设备检测效率,基于ARM和FPGA设计了一种CAN总线检测系统。设计硬件电路时采用了功能模块化方法,对ARM模块、FPGA模块和CAN总线接口电路分别进行设计。在FPGA内部采用了自顶向下的方法进行逻辑设计。在设计中针对多接口集成问题,采用ARM微控制器设计了USB和以太网两种接口,两个接口可独立工作并完成数据交互。完成设计后,进行了仿真验证和硬件调试,结果表明该系统可有效实现CAN总线数据的检测及测试。In order to make the data communication between the computer and 1553 B bus much easier and faster,and improve the detection efficiency of 1553 B bus equipment,a CAN bus detecting system was designed based on ARM and FPGA. With modular method for the hardware circuit,the ARM module,the FPGA module and the bus interface connecting were designed independently. The Top-Down method was used in the logic design based on FPGA. USB and Ethernet interfaces were designed based on ARM microcontroller for resolving the interface integration. Two interfaces could work independently. The results of software stimulation and hardware testing indicated that the detecting system could achieve data transmitting and detecting for CAN bus.
