分布式航电系统探讨与分析

摘要

As the brain and the nerve center of the plane ,Avinoics mainly complete the flight mission re-lated function ,occupy an important position in the airborne systems ,and play a key role .The progress of the Avionics are discussed from the seprated structure to joint structure and the IMA structure now in gen -eral use.Then the key technologies of the distributed Avionics are analyzed ,such as maintenance technol-ogy,network,operating system,middleware,system development method,and the technical support tools, etc.In the end,the development trend of distributed avionics is prospected ,it will further improve the de-gree of integration,and will go on developing in the crossed-platform,intelligent and networked direction , by importing high-end technologies such as artificial intelligence ,mode recognition and integrated sensor system .%航电系统作为飞机的“大脑”和“神经中枢”，主要完成与飞行任务相关的功能，在机载系统中占有重要地位。探讨了航电系统从分离式结构到联合式结构再到现在普遍应用的IMA结构的发展历程；分析了分布式航电系统发展到现今阶段所应用的关键技术，如维护技术、网络、操作系统、中间件、系统开发方法及支撑工具等；展望了分布式航电系统的发展趋势：它将会进一步提高综合化程度，引入人工智能、模式识别及传感器系统综合等高端技术，向着跨平台、智能化、网络化的方向发展。
