在利用自动测试系统对外挂装置进行测试时,通常一种型号的外挂装置就要有一种与之配套的信号适配器,这样一方面对测试资源造成了浪费,一方面增加了整个测试系统的重量和体积;通过对某型飞机所列装的外挂装置测试信号的分析和对多种型号外挂装置单适配器设计方法的研究,提出了测试信号整合的方法,进而减少测试接口适配器的数量和提高系统资源的利用率,并利用开关矩阵完成测试信号的快速切换,满足多项测试功能实时测试的需要。
In the use of automated test system to test the plug-in device, usually a type of plug-in device must have a matching signal adapter, which on the one hand, the test resources wereted, while increasing the weight of the entire test system and Volume; Through the analysis of the test signal of the plug-in unit installed in a certain type of aircraft and the research on the design method of single adapter for various types of plug-in units, a method of integrating the test signals is proposed to reduce the number of testing interface adapters and increase system resources The use of switching matrix test signal to complete the rapid switch to meet the needs of a number of real-time testing of test functions.
