Abstract:In order to meet the needs of real-time monitoring of large-scale civil aircraft test flight, this paper designs and develops real-time processing software for telemetry data. The software includes two parts: back-end analysis service and front-end display software.The back-end parsing service adopts multi-thread scheduling technology to realize the reception of IRIG 106 CH10 data, the parsing of PCM data and the real-time storage of data in working modes such as real-time status and data playback.The front-end display software adopts the MVVM design mode based on the WPF framework, including sub-modules such as task management, parameter configuration, algorithm processing and data synchronization.The software realizes the real-time processing, analysis and forwarding of no less than 8,000 telemetry data of a domestic large passenger aircraft, which meets the real-time monitoring requirements during the flight test and provides a strong guarantee for the safe development of the flight test mission.
