在飞行试验中,采集ARINC429总线是获取飞行试验数据重要的一环。早期的ARINC429总线以字为单位进行数据传输,试飞测试系统有良好的解决方案,然而最新出现的以消息流为传输单位的ARINC429总线,却无法良好的去解决方案。针对这一问题,本文列举了若干解决方案,并分析其优缺点,详细论述了一种最优的解决方案,并通过实验验证了这一方案的可行性,解决了新型ARINC429总线无法实时采集的工程问题。
In flight tests, acquiring the ARINC429 bus is an important part of obtaining flight test data. Early ARINC429 bus in word units for data transmission, test flight test system has a good solution, but the latest message flow for the transmission unit ARINC429 bus, but can not be a good solution. In view of this problem, this article lists a number of solutions, and analysis of its advantages and disadvantages, a detailed discussion of an optimal solution and experimentally verified the feasibility of this program to solve the new ARINC429 bus can not be collected in real time Engineering problems.
