Detailed Testability Design Method and Technique for Modern Airplane

摘要:

测试性详细设计是现代飞机顶层测试性设计的后续工作,根据现有飞机设计体系的构成,分飞机级、系统级、机载设备级3个层次论述了飞机测试性详细设计的方法；从综合诊断设计、故障信息显示以及故障告警3个方面阐述了飞机级测试性详细设计的内容；提炼了系统级测试性详细设计工作的组成,针对航电系统给出了通用、典型的测试性详细设计方法-基于模块测试与维护总线的边界扫描技术；详细论述了成品测试性详细设计,即BIT设计的准则及具体内容；论文的工作紧密结合在研型号的实际需求,有很好的工程实用价值。

Abstract:

For testability design of modern airplane systems, program should be detailed further based on top level testability design. According to the aircraft system, detailed testability design includes three levels, which are airplane level, system level and equipment level. For the airplane level, integrated diagnosis, fault message display and report are described. For system level, a typical universal technique, i.e., module test and maintenance bus(MTM-Bus) based boundary scan is proposed. Bus configuration and hierarchy test structure are given. For product level, BIT design guide line and detailed content are set forth. This paper is proposed based on the requirement and engineering practice of airplane being developed, which may be helpful for airplane testability design.
