摘要
ARINC659总线是一种标准的多点串行通信总线,具有完备的数据通信确定性和容错性特点,非常适合在对可靠性和冗余容错性要求较高的航天器综合电子系统中作为标准背板总线。文章在对ARINC659总线架构以及通信机制研究的基础上,结合综合电子系统的标准总线体系结构,重点对基于ARINC659总线的综合电子硬件模块、软件驱动程序和表程序设计等内容进行了详细描述。应用ARINC659总线,不仅能提升航天器综合电子通信的确定性和容错性,也能使综合电子系统的设计由事件触发向时间触发模式转变,由集中式控制管理向分布式并行处理转变,从而显著提升航天器综合电子系统的故障定位、并行数据处理、快速组装与测试能力,以及提高航天器综合电子系统资源的利用率。
The ARINC659 bus is a standard muti-point serial communication bus,with complete certainty and fault-tolerant data communication features,and ideal for standard backplane bus of the spacecraft avionics system which requires high reliability and fault tolerance and redundancy.On the basis of the studies of ARINC659 bus architecture and communication mechanism,in combination with spacecraft avionics system standard bus architecture,expounds the design of hardware module,software driver and table program.The application of the ARINC659 bus not only improves the deterministic and fault-tolerance communication of spacecraft avionics,but also makes a design conversion of avionics from event-triggered to time-triggered and from centralized management to distributed control,which significantly enhances the capability of fault detection,parallel data processing,rapid assembly and testing,and also improves resource utilization of spacecraft avionics system.
