Embodiment Construction

[0033] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, this embodiment provides a specific implementation process of an integrated avionics system software deployment control method:

[0035] 1. Assign a file identification code to each preload file

[0036] Each pre-loaded item file is assigned a file identification number, either through a software program or manually. The file identification code generation process is as follows: figure 2 shown.

[0037] The file identification code format is: AAA-BBB-CCC-DDD-EEE.

[0038] AAA is the supplier logo, consisting of uppercase letters and numbers;

[0039] BBB is the identification of the whole machine, which is composed of uppercase letters and numbers. If it is a single module, the value is 000;

[0040] CCC is the module identification, consisting of uppe...

Abstract

The invention discloses an integrated avionics system software deployment control method. According to the method, various software and hardware combination problems and repeated deployment of the same file which may occur when software loading deployment is carried out in a laboratory or an external field at present can be effectively avoided, and maintainability and reliability of the comprehensive modular avionics system are improved. The method mainly comprises the following steps: 1, counting all files required by a target machine, and creating a deployment configuration table in the target machine; 2, embedding a CRC value and a file identification code into each preloading item file; 3, loading and storing the preloading item file; and 4, completing the deployment of the preloadingitem file according to the deployment configuration table.

Description

technical field [0001] The invention relates to the technical field of airborne embedded software, and in particular provides a comprehensive avionics system software deployment control method. Background technique [0002] The comprehensive modular avionics system is rapidly developing in the direction of structural integration, hardware sharing, functional software and information networking. The volume, power consumption and weight of equipment are continuously decreasing. In the past, many functions realized by hardware are replaced by software. Realization, the status and function of airborne software have been greatly improved. What follows is that the software and hardware composition of the integrated modular avionics system is becoming more and more complex, and the number of software and configuration files that need to be loaded is large. In some projects, there may be as many as 10 software configuration items to be loaded on a single module. , There are hundred...
