机弹载总线网络的层次化评估方法研究

Research on Method for Hierarchical Evaluation to Bus and Network of Airborne and Missile borne

机弹载总线网络技术已成为飞行器、导弹信息综合化系统的关键使能技术,为保证总线网络产品的质量,应对其进行全面的评估。分析归纳了机弹载总线网络的评估要求,基于机弹载总线网络的层次化体系结构,提出了层次化评估准则;设计了评估要求与评估准则之间、评估准则与评估方法之间的对应分析表。给出了某飞机航电系统AFDX网络的评估案例,结果表明,层次化评估准则与方法具有通用性和可操作性的特点,能够高效地评估总线网络特性,有助于机弹载总线网络的全面评估。

The bus and network technology has become the key enabling technology of aircraft and missile information integrated system.The bus and network products should be fully evaluated to ensure the quality.The evaluation requirements of the airborne and missile bus network are summarized in this paper.Based on the hierarchical architecture of the airborne and missile borne bus network,hierarchical evaluation criteria are proposed.The corresponding table of the evaluation requirements and the criteria was designed.The corresponding table of evaluation criteria and evaluation method was designed.The evaluation criteria and methods have features of universality and operability.Finally,an evaluation case of AFDX network of an aircraft avionics system was presented,the results show that the proposed hierarchical evaluation criteria and method can effectively evaluate the characteristics of the bus network and is helpful for the overall evaluation of the airborne and missile borne bus network.
