某型飞机通电时显示控制管理分系统的右下视显示器(以下简称下显)存在视频信号串扰现象,即显示的画面背景中叠加了其他通道的显示信息(俯仰刻度数字的水印状)。特别是当下显在显示时钟、天地圆等大面积填充画面时,其他通道的画面显示串扰尤为明显。严重影响了飞行员对显示信息的识别。经过大量的分析和验证,问题得到彻底的解决。消除了串扰,提高了飞行员对显示信息正确识别,为飞机顺利完成飞行引导和作战任务提供了有力的保证。
When a certain type of aircraft is powered on, the video signal crosstalk phenomenon exists in the right-down view display (hereinafter referred to as the under display) of the display control management subsystem. That is, the display information of other channels (watermark-like digital elevation scale) is superimposed on the background of the displayed picture. In particular, the moment shows the clock, world circle and other large-scale fill the screen, the other channels of the picture shows crosstalk is particularly evident. Seriously affecting the pilots on the display of information recognition. After a lot of analysis and verification, the problem has been completely solved. Eliminate crosstalk, improve the pilot’s correct identification of the displayed information, and provide a powerful guarantee for the aircraft to successfully complete the flight guidance and combat missions.
