综合航电分区间通信元模型设计研究

Design of Meta-model of Integrated Modular Avionic Inter-partition Communication

针对当前综合模块化航空电子系统(IMA)开发中存在的问题,提出一种基于特定领域建模的综合航电分区间通信元模型的设计开发方法。通过分析航电系统分区间通信原理,抽取分区间通信的特性,采用基于面向特定领域的元建模分析方法,构建了综合航电分区间通信的元模型,通过元模型解析器生成了面向领域的建模语言,通过模型解释器将应用模型自动生成系统通信配置文件。以模块内部两分区间通信系统为实例对象进行了验证,结果表明该建模语言,具有较好的可理解性、易用性,可显著提高航电系统的开发效率,为基于元模型的综合航电系统建模方法奠定基础。

To solve the development problems of current integrated modular avionic(IMA)system,a development method based on domain-oriented meta-model of inter?partition communication was proposed. Through analyzing the communication principle between the avionics system partition and extract the characteristics,the inter-partition communication meta-model was constructed,then the domain-oriented meta-modeling languages was generated by meta-model parser and the application model used the model parser to generate the communication configure file automatically. Validated through the two partition communication in same module,the result shows that the model language has good intelligibility and usability,and can significantly improve the development efficiency of the avionics system,makes a basis of modeling method of integrated avionics system based on the meta-model.
