民机试飞遥测实时数据处理软件设计与研发

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

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,实现在实时处理及数据回放等不同工作模式下IRIG 106 CH10遥测数据的接收和PCM参数数据、PCM嵌入式视频流的解析和实时存储;前端显示软件基于WPF框架开发,包括任务管理、参数配置、算法处理和数据同步等功能模块;经实际测试,软件实现了国产某大型客机超过15000个试飞遥测数据及多路视频的实时解析、计算和转发,成功驱动了实时监控终端的相关应用,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。

In order to meet the real-time monitoring requirement of large-scale civil aircraft test flight,a set of real-time processing software for telemetry data is designed and developed.This software is composed of the back-end analysis service and front-end display software.The back-end parsing service adopts the multi-thread scheduling technology to realize the reception of IRIG 106 CH10 data and the parsing and real-time storage of Pulse Code Modulation(PCM)parameters and PCM embedded video stream under different working modes such as the real-time processing and data playback.The front-end display software is developed based on the WPF framework,including the functional modules such as task management,parameter configuration,algorithm processing and data synchronization.After the actual testing,the software has realized the real-time analysis,calculation and forwarding of no less than 15,000 test flights telemetry data and multi-channel video of a domestic large passenger aircraft,it is successfully driven the application of the real-time monitoring terminal,and met the real-time monitoring requirement during the test flight process,which provides a strong guarantee for the development of the flight test mission.
