Embodiment Construction

[0054] Below in conjunction with accompanying drawing, each part design method in the present invention is further described:

[0055] A kind of airborne computer software general frame design method of the present invention, the concrete steps of this method are as follows:

[0056] Step 1: Establish a software development environment and create a project

[0057] 1) Establish an application software development environment based on the VxWorks operating system

[0058] The ordinary PC is used as the host machine, and the onboard computer is used as the target machine. Tornado is installed on the host machine, and the target machine can run the VxWorks operating system, and the two parties establish a connection through Ethernet or serial port.

[0059] 2) Establish application software engineering on the Tornado integrated development environment.

[0060] Build steps: run Tornado → select the File menu → select the New Project... menu item → select the type of project to...

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 ...
