[0040] Introduction to related concepts

[0041] 1. Partition: Partition is the core concept proposed by ARINC 653. Partition ensures the time-space isolation of the system. One or more processes can exist in a partition at the same time, and share the system resources of the partition.

[0042]2. Partition scheduling: Partition scheduling is to allocate CPU resources according to the preset cycle time sequence. Each partition is activated and runs according ...

Abstract

The invention discloses a virtual ARINC 653 simulation verification platform, and relates to the field of airborne embedded simulation software. The invention aims at solving the problems that an existing real-time operating system based on the ARINC 653 standard is high in resource configuration requirement and poor in universality due to the fact that source codes are not public. The platform comprises partition management used for creating a plurality of partitions according to an XML configuration file and carrying out partition configuration on the partitions; scheduling the plurality ofpartitions according to a time window rotation mode, and scheduling the plurality of processes included in the partitions according to a priority preemption mode; the communication management module is used for completing communication between partitions based on the sampling port and the queue port according to a shared memory mechanism and partition configuration; completing communication between processes in the partitions based on the blackboard and the cache; and the health monitoring management module is used for receiving the error code sent by the partition and calling a processing function corresponding to the error code according to the error code to carry out error processing.

Description

technical field [0001] The invention relates to the field of airborne embedded simulation software, in particular to a virtual ARINC 653 simulation verification platform. Background technique [0002] In recent years, the aviation environment in the era of information intelligence has become more and more complex, and the avionics system has gradually developed in the direction of intelligence, modularization, and integration. The addition of complex hardware and software resources puts forward higher requirements on the processing capability and weight control of the avionics system. The traditional joint architecture lacks security, portability, and scalability, and no longer meets the development requirements of the current highly integrated avionics system. Therefore, the ARINC653 standard based on Integrated Modular Avionic (IMA) is more and more widely used in the field of avionics. The ARINC 653 standard is a specification based on the IMA architecture for the avion...
