民机试飞遥测地面实时数据处理软件设计与研发

为了满足大型民机试飞实时监控的需求，针对遥测数据设计研发了一套实时处理软件，软件包含后端解析服务和前端显示软件两大部分；后端解析服务采用多线程调度技术，实现实时处理及数据回放等不同工作模式下IRIG 106 CH10数据的接收、PCM数据的解析和数据的实时存储；前端显示软件基于WPF框架采用MVVM设计模式开发，包括任务管理、参数配置、算法处理和数据同步等子模块；经实际测试，软件实现了国产某大型客机不少于8000个遥测数据和多路视频的实时解析、分析和转发，满足了试飞过程中的实时监控需求，为试飞任务的安全开展提供了有力保障。

Design and Development of Telemetry Real-time Data Processing Software for Civil Aircraft Flight Test

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.
