Abstract

The invention discloses a general frame design method of airborne computer software , which comprises seven steps as follows: step1, establishing software development environment and construction; step2, establishing a time drive task; step3, establishing an event drive task; step4, establishing a background operation task; step5, establishing a clock interrupt service program; step6, establishing an interface program; and step7, establishing an initialization program. The invention abstracts all related functions of the prior airborne computer application software to obtain a general frame so as to realize corresponding tasks according to different requests during developing specific software so that the purpose of rapidly developing is achieved, and effectively improves the portability, the reliability and the standardability of the prior direct development method. The general frame design method is successfully applied to the contractible-scaled testing aircraft of an aircraft and has wide practical value and application prospect.

Description

(1) Technical field:

[0001] The invention provides a method for designing a general framework of airborne computer software, which belongs to the technical field of airborne computer software, and specifically relates to software task division, priority allocation, inter-task communication design, and the like. (two) background technology:

[0002] Airborne computer software is divided into system execution software and application software according to functions. System execution software mainly provides underlying support programs such as interface drivers and task schedulers for system operation. Realize various control functions, detection functions, fault handling functions, etc. of the system.

[0003] At present, in the development process of airborne computer software, the system execution software is mostly realized by the embedded real-time operating system, while the application software is directly developed based on the operating system based on the developer's ...
