摘要
为了实现机载测距机测试设备的国产化,设计并开发了机载测距机测试平台。平台采用模块化设计,以VME总线为基础联结各个测试资源。平台能够模拟测距机多种工作环境,使用甚高频信号源向测距机加载相应信号,对测距机各输出信号进行测量与分析,实现对测距机、接收机的自动/手动测试。另外,系统内置模拟测试模块以及故障设置功能,可以用于相关专业技能训练。平台应用于一线维修企业与我校实践教学中,达到了设计效果,具有较高的实用价值。
In order to realize the localization of the airborne distance measuring equipment(DME),the testing platform of the airborne DME was designed and developed.The platform adopts modular design,and is connected with each test resource through VME bus.With the platform,a variety of working environments of the DME can be simulated,the VHF signal source is used to load the corresponding signals to DME,and the output signals of DME are measured and analyzed to realize the automatic/manual testing of the DME receiver.In addition,the simulation test module built in the system and fault setting function can be used for the relevant professional skills training.The platform is applied to front-line maintenance companies and practical teaching in CAUC,which achieves the design effect and has high practical value.
