摘　　要：针对机载CAN总线的测试需求,设计了采用STM32F105作为主控CPU的机载CAN总线中继器,实现了不同传输速率的CAN总线报文接收。主要阐述了中继器的功能,详细介绍了中继器的软硬件设计,分别在实验室和机载环境条件下进行了CAN总线数据采集,经试验验证机载CAN中继器对机载CAN总线无干扰,同时机载CAN总线与CAN中继器之间的电缆连接长度为40m时,测试结果正确,整个测试系统工作稳定、可靠,可以满足机载CAN总线数据测试的要求。Foucs on the application requirement of airborne testing system on CAN bus,the scheme of CAN repeater design was proposed using STM32F105 as the master control CPU,and CAN bus message receiving with different transmitting rate was completed.The function of repeater was mainly stated,meanwhile the software and hardware design was introduced in detail.Data acquisition on CAN bus was carried on in the laboratory and airborne condition,where it was verified that the CAN repeater never disturbed the CAN bus and the testing result was correct with the 40 mcable connection length between the airborne CAN bus and CAN repeater.The whole testing system worded so steadily and reliably that could satisfy the requirement of airborne CAN data test.
