摘　　要：本文首先讨论了航空电子系统综合化设计的必要性,以及给航电系统带来的收益。在此基础上,表明了必须辩证的看待系统综合化设计的收益和技术风险。在综合化设计的技术风险分析方面,首先举证了综合化设计可能对系统指标带来影响;其次考察了综合化设计对系统电磁兼容带来的挑战及其应对措施;然后分析了由于模块通用带来的冗余设计;最后介绍了由于硬件资源共用带来系统资源管理难度的增加及其初步解决方案。文章末尾表达了综合化设计必须在收益和风险之间寻求一种平衡的理念,需根据型号工作的主要矛盾予以取舍。In this paper,the necessities of the integrated design of the avionics system and the gain to the avionics system are discussed.On this basis,it is shown that the benefits and technical risks of the integrated design of the system must be viewed dialectically.In depth analysis of technical risk integrated design,first of all to the examples of integrated design system may affect the index;this is followed by the integrated design of compatible challenges and countermeasures of system electromagnetic;and then analyzes the redundancy design of the general module;finally introduced the hardware resource sharing has brought increasing system the difficulty of resource management and its preliminary solution.At the end of the article,it is pointed out that integrated design must seek a balance between revenue and risk.We need to consider the main contradiction of model work.
