针对当前综合模块化航空电子系统(IMA)开发中存在的问题,提出了一种基于元模型的航电系统建模方法。该方法充分利用了基于特征的元建模理论,通过合理划分和描述构成整体的各部分及其相互关系,构建航电系统领域的元模型。通过建模工具将元模型解释成面向领域的建模语言,在此基础上可构建具体的航电系统模型。以航电系统为实施对象进行了验证,结果表明该方法可显著提高航电系统的开发效率。
Aiming at the existing problems in the development of integrated avionics system (IMA), a meta-model-based modeling method of avionics system is proposed. The method takes full advantage of the feature-based meta-modeling theory and constructs the meta-model in the avionics system by reasonably dividing and describing the parts that make up the whole and their mutual relations. Through the modeling tools, the metamodel is interpreted as a domain-oriented modeling language, on the basis of which a specific avionics system model can be constructed. The verification of the avionics system is carried out. The results show that this method can significantly improve the development efficiency of the avionics system.
