客舱内部通讯数据指令器的核心部件是导向器(DIRECTOR)。它用于控制、监控和测试乘务员及旅客专用的客舱系统。依据客舱内部通讯数据指令器(CIDS)的CMM手册,分析出客舱内部通讯数据指令器(CIDS)的整体功能和其核心部件导向器(DIRECTOR)的各功能模块,并合理的提出了故障诊断的方法,从而为设计客舱内部通讯数据指令器(CIDS)的检测方案打下基础。 At the heart of the cabin intercom data commander is the DIRECTOR. It is used to control, monitor and test cabin crew and passenger-specific cabin systems. Based on the CMM manual of Cabin Internal Communication Data Commander (CIDS), the overall functions of CIDS and the functional modules of its DIRECTOR are analyzed, and the fault diagnosis Method, which laid the foundation for the design of the detection scheme for cabin intercom data communicator (CIDS).
