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 an airborne operating system partition communication method under Windows, which is used to solve the technical problem of poor real-time performance of the existing partition communication method. The technical solution is to build a comprehensive modular avionics software simulation and verification platform standardized by ARINC653. On the virtual ARINC653 operating system, the high-efficiency communication of a large amount of data is realized through the use of shared memory, and the communication function requirements of ARINC653 are completed through the mechanism of blackboard, cache, sampling and queue. At the same time, the design of the system call interface shields the underlying physical implementation, combined with the system architecture design of the real environment. After testing, the communication method of the airborne operating system partition under Windows of the present invention has good real-time performance.

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 ...
