基于ARINC818机载音视频的测试方案设计

A Test Scheme Design of Airborne Audio and Video Based on ARINC for the on-board Audio&Video

摘要:

某型飞机在试飞测试任务过程中,需要对多路机载音视频进行抽引、采集、记录与遥测,用于飞机实时动态监控与事后回放分析。该型飞机的显控数据采用ARINC818(又名航空电子视频总线Avionics Digital Video Bus)专用图像传输协议进行光纤视频传输,对ARINC818总线视频的抽引采集在试飞任务中为首次。由于目前机载采集系统的限制,本文设计了一种基于ARINC818的机载测试系统,满足了该型飞机多通道、高分辨率、多视频格式的信号采集记录。

Abstract:

During the test mission of an aircraft, the on-board Audio Video acquisition、recording and telemetry are needed,which is used for dynamic monitor and playback after the event. The transmission of video data is based on the protocol of ARINC818(namely Avionics Digital Video Bus) through the fiber, which is the first time in the test mission. On account of the limit of the on-board equipment, this paper designed a test system based on ARINC818, which meeting the acquisition and record of multi-channel, different resolutions and multiple formats.
