机载航空电子启动类装置通用检测平台研究

摘要

Aviation activation panel is a avionic device which can be used to deal with the pilot's operation,control avionics subsystem on/off,and communicate with the main control processor.In order to check the failure conditions and judge whether its performance meets the requirements or not,a custom-built detection equipment is made,which can be used to simulate the working environment on the plane of aviation activation panel and the other line replaceable units.According to AAP operating principles,operating mode,interface definitions and the requirements of the power sources,in/out signals and communication modes,its universal detection platform is built.%机载航空电子启动类装置(AAP)是一种能够处理飞行员操作和外部离散信号、控制航电分系统通/断,与主控处理机通信、接受和综合处理系统内的数据和状态的航空电子设备.其性能检测是采用专用检测设备对外场可更换单元与AAP的机上工作环境进行模拟,由此检查AAP的故障情况,可判断其工作状态与性能是否符合要求.针对目前多机型AAP组成原理、工作方式、接口定义相同或相近的情况,对其供电电源、输入信号、输出信号、通信方式进行归纳总结,初步完成了AAP通用检测平台的基本构建.
