摘　　要：针对C919飞机航电AFDX总线测试需求,设计了基于FPGA的数据采集设备,实现了AFDX航电总线的100%原始数据转发、实时解析功能。主要阐述了AFDX总线采集需要实现的功能和采集方案,详细介绍了AFDX数据采集设备的软硬件设计,分别进行了仿真测试和航电实验室测试,经验证AFDX采集模块对机载AFDX总线无干扰,整个实验测试结果正确,AFDX采集设备工作稳定、可靠,可以满足AFDX总线数据的测试需求。According to the test requirements of C919 AFDX aircraft avionics bus,a data acquisition device based on FP- GA is designed, which realized the 100% raw data forwarding and real-time analysis function of AFDX avionics bus. This paper mainly describes the plan for AFDX bus acquisition and detailed introduces the design of AFDX acquisition e- quipment ~s hardware and software. Which conduct The simulation test and the avionics laboratory test, the results indi- cated that the acquisition module has no effect on airborne AFDX bus, and which is correct. In the end, AFDX acquisi- tion module is stable, reliable, and can meet the test requirements of AFDX bus data.
