摘　　要：综合航电开放式软件设计技术是新一代航电系统支持平台机载实时容错分布式计算机系统的重点,它的设计直接或间接地关系到新一代综合航电系统的性能和成本。针对先进综合航电系统的特点、性能要求,对目前机载计算机软件系统存在的可靠性、安全性低,不易移植,成本高,层次分割不清晰,功能独立性差,对系统容错支持能力弱等缺陷,提出了"三层栈结构"的软件设计新思想,通过标准接口(物理接口和逻辑接口)使得层与层、模块与模块之间得以分开,实现了功能模块化、软硬件隔离性、软件的再利用性、可剪裁性、易维护性,以适应不断增长的航空电子系统任务能力需求,为新一代航电系统支持平台机载实时容错分布式计算机系统的开发、研制提供了可靠的保证。Integrated avionics open software design technique are important research topic ofthe new generation avionics systems support platform i.e.airboren real-time fault-tolerance distributed computer system, its design relation performance and cost directly of the new generation integrated avionics systems. To feature and performance of advanced integrated avionics systems required, for the present airborne computer software system existent reliability, security low, uneasy to transplant, cost high, hierarchy partition blurring, function independence difference, raise the three layer stack design idea, via standard interface （physics and logic interface） usable layer and laver, module and module get partition, implement function modularization, software hardware isolation, software reutilize, tailor, maintenance, adaptation continual increase requirement of avionics systems task ability, for new generation avionics systems support platform airboren real-time fault-tolerance distributed computer systems research and development provide assurance unfailingly.
