ARINC429总线广泛应用于民用飞机中,在飞行试验中,消息重复型ARINC429事件信息的实时监控占用很大的遥测带宽资源;采用机载嵌入式数据处理模块,通过将其嵌入到机载测试系统中,通过采集器底板总线获取ARINC429采集模块采集到的数据,对飞机事件信息进行解析处理,并将处理结果通过遥测系统遥测下传至地面监控中心,大大降低了遥测带宽需求,对于飞行试验实时安全监控有重要意义。
The ARINC429 bus is widely used in commercial aircraft. In flight test, real-time monitoring of message repetitive ARINC429 event information occupies a large telemetry bandwidth resource. The onboard embedded data processing module is embedded into the airborne test system , Through the collector backplane bus acquisition ARINC429 acquisition module to collect data on the aircraft event information analysis and processing results and telemetry system telemetry down to the ground monitoring center, greatly reducing the telemetry bandwidth requirements for flight test real-time safety Monitoring is important.
