摘　　要：为解决航电系统仿真验证过程中大多数ARINC429板卡软件定时不精确、不可靠的问题,拟从硬件上实现多通道、并行、高精度定时循环发送,采用基于标准SystemVerilog语言智能配置循环存储器的方法实现优化定时功能,提出一种多通道航空总线通信板卡设计方案。该方法采用通用网络接口与计算机连接,在基于LabVIEW的航空总线测试平台下,对所设计板卡进行测试和验证,结果表明该方法能够满足多个通道并行定时发送数据的要求,并且各项指标符合ARINC429电气标准。In order to solve the problem that most ARINC429 card softwares has imprecise and unreliable timing in valida-tion of avionics system simulation,it is planned to realize multi-channel,parallel and high-accuracy timing cycle transmission by hardware,and implement the optimal timing function with the method that uses SystemVerilog language to intelligently con-figure a cyclic memory. A design scheme of multi-channel avionics bus communication card is proposed,in which a common network interface is adopted to connect with the computer. The designed board card was tested and validated on the LabVIEW-based aviation bus test platform. The results shows that this method can meet the requirements of parallel and timing data trans-mission in multiple channels,and each index meets ARINC429 electrical standard.
