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。
Abstract
Based on the application requirements of small airplane avionic systemwe designed a logical framework of the systemand 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 proposedincluding real-time multi-channel data acquisitionredundancy path realization and data loading.Then the specific realization method was given.This system was implemented on VxWorks embedded real-time operating systemand has been applied in an integrated avionics project for a certain type of aircraft.
