摘要
ARINC 659背板总线适用于高安全性和高可靠性需求的飞机机载计算机通信系统。分析ARINC659背板总线结构、传输方式、介质访问方式、开发语言和帧描述语言命令等总线协议的关键内容,以及数据吞吐量、故障检测与隔离、系统容错能力、数据传输确定性等特点。介绍4余度飞控系统的总线应用、系统架构以及计算机间的总线桥接,通过帧描述语言设计仿真测试软件。
ARINC 659 backplane data bus is suitable for high security and high reliability requirements of aircraft airborne computer communication systems.Some essential elements in the ARINC 659 data bus protocol,such as structure,transport mode,media access method,development language and frame language description are analyzed,at the same time,data throughput,fault detection and isolation,system fault tolerance and data transmission certainty and so on are construed.Data bus application,system architecture and bus bridge between computers of 4-redundance flight control system are introduced.Simulation test software based on the technique of frame description language is used to test the data bus application system.
