Embodiment Construction

[0017] refer to Figure 1-3 . The specific steps of the airborne operating system partition communication method under Windows of the present invention are as follows:

[0018] Step 1: Load the XML configuration file, parse the XML, and read the configuration information of the communication file. All communication information of an application can be known from the configuration file, including inter-partition communication and inter-partition communication. Inter-partition communication includes sampling port numbers, queue port numbers and partition names, and intra-partition communication includes the first address of its blackboard and cache queue. .

[0019] Step 2. If the partition application needs to perform inter-partition communication, it needs to obtain the partition number and port number of the destination. If the partition application needs to perform intra-partition communication, it needs to obtain the cache number and blackboard number.

[0020] Step 3. I...

Abstract

The invention discloses a partition communication method of an onboard operating system under Windows, and is used for solving the technical problem of poor instantaneity of a conventional partition communication method. The partition communication method has a technical scheme that an integrated modularization avionics software simulation and verification platform of an ARINC653 specification is set up. On a virtual ARINC653 operating system, a shared memory is used to realize the efficient communication of a large data volume, and the communication function requirements of the ARINC653 are metthrough mechanisms of blackboards, caching, sampling and queues. Meanwhile, the physical implementation of a bottom layer is shielded through the design of a system calling interface, and a system architecture design of a true environment is combined. Through tests, the partition communication method of the onboard operating system under Windows exhibits good instantaneity.

Description

technical field [0001] The invention relates to a partition communication method, in particular to a partition communication method for an airborne operating system under Windows. Background technique [0002] The current research hotspot at home and abroad is to build an avionics software simulation verification platform based on virtualization technology, and use virtualization technology to simulate real airborne equipment, such as radar, radio navigator, etc., to realize avionics software on a single computer. development, debugging, and verification. This method is almost completely separated from the airborne equipment, meets the needs of the new generation of avionics systems, improves the development efficiency of avionics software, and reduces the verification cost of avionics software. [0003] There is already a mature integrated avionics real-time embedded operating system ARINC653 based on IMA architecture in foreign countries. ARINC653 proposes the concept of ...
