Multi-source multi-type data playback device based on time synchronization

Abstract

The invention relates to a multi-source multi-type data playback device, in particular to a multi-source multi-type data playback device based on time synchronization, which belongs to the field of aircraft avionics system design. The invention discloses a multi-source multi-type data playback device based on time synchronization. The multi-source multi-type data playback device comprises an airborne multi-equipment multi-type data synchronous processing device and a ground multi-type data synchronous playback processing device, wherein the airborne multi-equipment multi-type data synchronous processing device is used for acquiring and receiving generated flight parameter data, 1553B bus monitoring data, audio data and video data; and the ground multi-type data synchronous playback processing device is used for carrying out synchronous playback processing on reports, curves, audios and multi-channel videos after arranging and aligning multi-source data according to time information of different types of data. The method has the following advantages that 1, the flight performance evaluation level is improved; 2, a basis is provided for daily maintenance and fault isolation of the airplane; and 3, synchronous playback of a plurality of airplanes is realized.

Description

technical field [0001] The invention relates to a multi-source multi-type data playback device, in particular to a multi-source multi-type data playback device based on time synchronization, which belongs to the field of aircraft avionics system design. Background technique [0002] Flight commentary is to describe, comment and thoroughly analyze the problems that arise in the flight training process. It is also an exchange between people. They provide each other with the experience they have accumulated in the flight process and communicate with each other to improve flight performance. technology. Flight commentary plays a vital role in ensuring flight safety. It can discover hidden dangers and problems and make full preparations for the next flight. Therefore, flight commentary is a very important stage in the entire flight process. [0003] At present, the airborne flight parameter data, 1553B bus monitoring data, audio / video data, and event data are generated by differ...

AI Technical Summary

Problems solved by technology

[0003] At present, the airborne flight parameter data, 1553B bus monitoring data, audio / video data, and event data are generated by different data source devices, and different software is used for playback and analysis, and they are not synchronized with each other. Flight commentary, aircraft daily maintenance, Aircraft fault isolation and other problems cause a lot of trouble, which is not conducive to field troubleshooting and problem location
