摘要
当今基于ARINC653的综合化航空电子系统的应用日益广泛,分区作为ARINC653提出的任务调度和资源共享的核心概念,其相互间通信的可靠性和安全性成为航空电子系统要解决的重要问题。详细阐述了分区间通信监视的原理,并给出了一种可行的分区间通信监视器设计和实现方案。应用表明分区间通信监视器极大地改善和提高了航空电子系统的通信监控能力,为通信故障诊断和分析提供了依据。
Integrated Modular Avionics system based on ARINC653 are widely used today. Partition as a core concept of task scheduling and resource sharing issued in ARINC653 ,the reliability and safety of its inter-partiton communication becomes an important problem that should be solved for the Avionics system. The principle of inter- partition communication monitoring is introduced in details in this paper, and a reasonable design and implementation solution are provided. It is proven that the capability of monitoring and error diagnosing are improved by the inter- partition communication monitor in avionics system.
