飞机任务简报技术研究与实现

摘要

传统的机载数据记录系统只是将数据记录下来，在地面站下载后分析回放。由于机载设备记录的数据量巨大，地面下载、检索数据非常耗时，这大大降低了飞机的故障诊断速度及快速出动能力。本文提出了一种任务简报技术，在飞机飞行或执行任务过程中建立索引文件、事件文件，当飞行结束后，通过事件文件、索引文件快速下载与事件相关的数据片段。该技术能够显著提高数据下载、检索速度，对任务简报功能设计有一定参考价值。%Traditional on-board data recording system records many kinds of data, and the ground station downloads these data for analysis and replay. However, analysis task usually costs lots of time because of the huge amount of data. This greatly affects the speed of fault diagnosis and the ability of scramble. This paper describes the Aircraft Mission Brief. It can create index files and event files when the aircraft is flying. After landing, the ground station can quickly locate the moment when the event occurred, and download the relevant data pieces . This technology speeds up of data downloading and event locating , and provides a reference for studying the aircraft mission brief.
