Embodiment Construction

[0090] The present invention combines the standards and components of the architecture, from the perspective of the system, through the gradual refinement of system functions, and using the mapping method of each function or sub-function to the FACE component as a clue, proposes a hierarchical and componentized modeling method under the architecture, specifically Modeling process such as figure 1 shown.

[0091] Step 1: System function analysis: perform iterative analysis of system functions according to system requirements, divide a system into several subsystems, divide a subsystem into several subsystems or functions, and refine a function into multiple sub-functions, so that the system functions as much as possible refinement. Express the final system function analysis results in a system function tree, such as figure 2 shown.

[0092] The system function tree contains two types of nodes: system nodes and function nodes, where system nodes are divided into system nodes...

Abstract

The invention proposes a software system modeling method based on the standard framework FACE, including methods such as system componentization, data modeling, system I / O service modeling and component transmission service modeling. The modeling method proposed by the invention can guide the modeling of the avionics system architecture in my country, and can be used as a theoretical basis for the development of system modeling related tool chains and platforms under the FACE architecture for practical application. The invention is beneficial to improve software quality and development efficiency, enhance software portability, save development cost, facilitate rapid system integration, shorten system development cycle, and promote the formation of a unified open software architecture standard in the domestic aviation field. The present invention can be applied to high reliability, high reliability and high security fields, for example, software-intensive industries such as aviation field and spaceflight field.

Description

technical field [0001] The invention relates to a software system modeling method based on the FACE framework. Background technique [0002] The task importance and functional complexity of the new generation of avionics systems are getting higher and higher. At the same time, the rapid development of electronic information technology and computer technology, as well as the highly integrated design requirements have brought many challenges to the avionics system. Among them, the airborne software and Tight hardware binding, difficult system upgrades, and poor reusability are key factors leading to high development costs for avionics systems. The avionics system of my country's fourth-generation aircraft is still provided by a single developer for a specific set of needs, resulting in cumbersome system upgrade procedures, and the developed hardware and software cannot be reused on different types of aviation platforms or various similar functions. . At present, there are gen...
