为了解决虚拟航空验证系统中航电设备仿真数据协议帧兼容性和实时入库的问题，设计了一种工作于RTX实时环境下的ARINC429总线协议转换器。硬件设计采用FPGA+DM642结构，使用FPGA对ARINC429总线信号进行驱动，采用DM642对协议进行编码和解码，并将数据返回到PC端；在PC端使用RTX实时驱动完成上位机数据的交互，以保证协议转换的实时性。经测试，该设计方案能够得到正确的协议转换结果，并满足了虚拟验证系统对实时性的要求。

In order to satisfy the frame compatibility of protocol and storage in real time of simulation data for avionics equipment in virtual aviation verification system, the ARINC429 bus protocol converter working under RTX real time environment has been designed. In hardware design, FPGA+DM642 structure is adopted, FPGA is used for driving the ARINC429 bus signals, and DM642 is used for protocol encoding and decoding, and returning the data to PC. In PC, to guarantee real time performance for data exchange, RTX real time driving is used. Through tests, it is found that the design scheme can provide correct protocol conversion result, and meet the real time requirement for virtual verification system.
