摘　　要：以当前机载数据总线的异构性、综合化的趋势为背景,针对各种专用型总线测试系统缺乏通用性和可扩展性的局限,提出了一种通用的机载数据总线测试系统的设计方法,采用一种通用架构隐藏了不同机载总线测试系统的底层实现细节,将机载总线测试系统的共性流程抽象为通用实现层,从而增强了总线测试系统的通用性和可扩展性。采用几个典型的机载总线测试系统对本文所提出的通用架构进行了验证。实验结果表明,抽象层设计对总线测试系统的累计传输时延不超过2 ms,能够满足各种总线测试系统的测试需求。Based on the current heterogeneity and integration trend of the airborne data bus,this paper proposed a general design method of the airborne data bus testing system to resolve the limitation of the versatility and scalability of various dedicated bus testing systems. The method used a common architecture to hide the low-level implementation details of different airborne bus testing system and abstracted the common process of airborne bus testing system as a common implementation layer,thereby enhancing the versatility and scalability of bus testing system. The typical architecture proposed in this paper is validated by several typical airborne bus testing systems. Experimental results show that the cumulative transmission delays caused by the abstraction layer are not more than 2 ms,which can meet the requirements of a variety of bus testing system.
