摘　　要：基于小型飞机综合航电系统的应用需求,通过分析小型综合座舱电子系统组成结构,设计了系统逻辑架构,给出了飞行显示器与综合处理机的顶层功能流框图。提出了多通道数据的实时采集、冗余路径实现、数据加卸载等3项关键技术,给出了具体的设计实现方法。该系统在VxWorks嵌入式实时操作系统上实现,已在海鸥300飞机综合航电系统项目中安装使用。Based on the application requirements of small airplane avionic system, we designed a logical framework of the system, and put forward the top-level Functional Flow Block Diagram （FFBD） of flight display and integrated processed computer by analyzing the framework of small integrated cockpit avionic system. Three critical technologies were proposed, including real-time multi-channel data acquisition, redundancy path realization and data loading. Then the specific realization method was given. This system was implemented on VxWorks embedded real-time operating system, and has been applied in an integrated avionics project for a certain type of aircraft.
