The invention discloses a dual-redundancy graphic display device for an airborne display. A main hardware composition of MFD comprises seven functional modules: a graphic display control module, an interface bus module, a power module, an AFDX terminal module, a video optical fiber module, a liquid crystal display module, a light guide plate and the like, wherein the graphic display control module, the power supply module and the AFDX terminal module adopt a dual-redundancy design and are designed into two blocks, and the two blocks of hardware, software and functional performance are completely consistent and are hot backups for each other. The interface bus module is designed to be a board card, but is composed of two circuits with the same functions, and task backup is achieved. The dual-redundancy graphic display device of the airborne display has the advantages that a circuit design is simplified, and the functions are complete; reliability is high, power consumption is low, an anti-interference capability is high, and the structural design is stable and reliable; 100% domestication is adopted for components; and man-machine efficacy is optimized.
本发明公开了一种机载显示器双冗余图形显示装置,MFD主要硬件组成包括图形显示控制模块、接口总线模块、电源模块、AFDX终端模块、视频光纤模块、液晶显示模块和导光板等7种功能模块组成,其中,图形显示控制模块、电源模块和AFDX终端模块采用双冗余设计,各设计2块,且两块硬件、软件及功能性能完全一致,互为热备份。接口总线模块设计成1块板卡,但由由功能完全相同的两部分电路组成,任务备份,本发明实施例一种机载显示器双冗余图形显示装置,(1)电路设计精简,功能齐全;可靠性强、功耗低、抗干扰能力强,结构设计稳定、可靠;元器件选用100%国产化;人机功效优化。
