通过对国内外机载计算机“三化”趋势及现状的研究分析 ,说明机载计算机的通用化、系列化、组合化 (模块化 )已经具有了良好的基础。目前应主要推广核心数字模块、电源模块以及部分接口模块 ,这是实现“三化”的突破口 ,也是今后机载计算机“三化”研究的重点 Through the research and analysis on the trend and present situation of the “three modernization” of airborne computers at home and abroad, it shows that the generalization, serialization and combination (modularization) of onboard computers already have a good foundation. At present, the core digital modules, power modules and some interface modules should be mainly popularized, which is the breakthrough point to realize the “three changes” and also the focus of the “three changes” of airborne computers in the future
