摘　　要：以通用机载总线监控及测试系统研发为背景,针对接口控制文档(ICD)严重依赖于总线类型,缺乏通用性的现状,提出了一种通用的ICD设计方法。在软件层面上对接口控制文档的通用性进行高层抽象,并在此基础上设计和实现了通用的ICD数据模型和ICD解析器。在通用机载总线监控系统中对本文提出的方法进行了通用性验证和可行性验证。实验结果表明,使用此解析器,无需修改应用程序代码即可适配各种类型的机载总线;同时,高层抽象带来的总线传输时延不超过2 ms,满足总线测试系统的需求。Based on the research of universal airborne bus monitoring and testing system , this paperproposed a general design method of airborne bus interface control document aim at to solve thedependency of interface control document on the type of airborne bus , and the lack of ICA general ICD data model and ICD parser is designed and implemented base on the software high levelabstract of generality of ICD. The generality and practicability of this method was verified airborne bus monitoring system. Experimental results show that application codes can be adapted tovarious airborne bus without any modify when it use this general parser. Moreover , the bus transmission delay resulting from the high level abstract is lower than 2 ms , and meets the requirement osystem.
