Research and Implementation of Inter-partition Communication Monitoring in Avionics Systems

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.
