摘要
ARINC659总线是一个线型多节点串行通信总线,可以满足航空电子对可靠性、故障容忍度、完整性的要求,主要用于在线可更换模块之间的数据传送,其采用表驱动比例访问(TDPA)的通信机制,具有较高可靠性、高容错率以及较高的总线利用率,被广泛应用于现代大型军用、民用飞机中。文中提出了基于ARINC659总线的PMC卡设计及实现方案。首先介绍了HK659芯片,然后详细阐述了ARINC659总线的PMC卡实现方式,配套的命令表工具实现及命令表的设计,最终完成了系统应用验证。结果充分表明,该PMC卡的功能完备,性能良好。它可以满足系统应用的需求。
The ARINC659 bus is a linear multi node serial communication bus and can meet the needs of reliability,fault tolerance and integrity of avionics system,which is mainly used in the replacement of data transformations among modules online. It adopts table driven proportional access communication mechanism and has a high reliability,high error-tolerant rate and high utilization ratio of the bus. The ARINC659 bus is extensively used in modern large civilian and military aircrafts. Present the scheme of design and implementation of PM C card based on ARINC659 bus. Firstly propose HK659 chip,then elaborate on the way of PM C card realization in detail,subsidiary of the command list,and the design of command list. At last,it finishes the system application verification. The results fully show that the PM C card has the good equipments and good performances,which can meet the application demands of system.
