ARM-based graphic display control module in military airborne cockpit display system

Abstract

The invention discloses an ARM-based graphic display control module in a military airborne cockpit display system. The ARM-based graphic display control module is mainly composed of four hardware function modules and three software function modules, wherein the four hardware function modules are respectively a video acquisition card module, a core board module, a liquid crystal display module andan audio and video storage module, and the modules are cross-linked through a custom bus; and the three software function modules are respectively mini PCIE interface driving software, video playing software and voice module driving software.The ARM-based graphic display control module in the military airborne cockpit display system is high in reliability, low in power consumption, high in anti-interference capacity and stable and reliable in structural design; and the video resolution is effectively improved, so that the audio-video playing is smooth.

Description

technical field [0001] The invention relates to the aviation field, in particular to an ARM-based graphic display control module in a military airborne cockpit display system. Background technique [0002] VTR is an airborne device installed in the cockpit of a fighter jet, which is used to record the images of the onboard display and the voice of the call during the flight for ground analysis. VTR adopts the analog recording method and uses magnetic tape as the recording medium. In view of the backward level of anti-seismic design and production of domestic magnetic head-related mechanical structures, this equipment has always relied on imports. VTR can record one channel of analog video and one channel of analog audio. Since most third-generation fighters have several displays, the front end uses a special video distribution module to output multiple channels of video to the VTR at intervals for recording. The video recorded on the VTR tape The information can be split, p...

Problems solved by technology

VTR can record one channel of analog video and one channel of analog audio. Since most third-generation fighters have several displays, the front end uses a special video distribution module to output multiple channels of video to the VTR at intervals for recording. The video recorded on the VTR tape The information can be split, processed, collected, compressed, and played back through the huge and complex supporting equipment on the ground. Poor, which greatly affects the analysis of the flight situation of the troops, and can no longer meet the needs of fighters to enhance combat effectiveness
