KVM-OSD技术在指火控系统中的应用

摘要

为了满足军用集成运算环境对外部操控与显示设备的特殊要求,采用高分辨率视频切换技术、高速差分信号切换芯片与OSD字符叠加技术设计了KVM切换模块,并应用于指火控系统.该模块采用按键分别控制VGA视频与USB键盘、鼠标切换.经模块级、单元级与可靠性考核试验以及在指火控系统中的应用证明了该模块具有良好的稳定性与可靠性,方便了使用人员的操作.%In order to meet the special needs of external manipulation and display device in military integrated operational environment, KVM switch module is designed using high-resolution video switch technology, high-speed differential signal switch chip and OSD character overlapping technology, which is used in command and fire-control system,, This module can be used for VGA video and USB keyboard and mouse switching. Through module-level, unit-level and reliability evaluation experiments and application in command and fire-control system, this module is demonstrated stable, reliable and convenient for users to operate.
