继电器盒自动测试设备研究

摘要

A certain helicopter’ s relay boxes contain a large number of relays and most of the relays don’ t use independent power sup-ply. As a consequence, it is inconvenient to do tests and experiments manually. To overcome this, a new automatic test device is designed, which integrates multiple mature and advanced techniques, including software techniques and hardware techniques. Using this new test device, logical functions of each unit of the relay boxes can be accurately tested and faults can be precisely located.%由于某型直升机继电器盒内继电器较多，且大多数继电器都不是独立供电，采用人工接线通电检测的方式给该型装备的检测和试验工作带来诸多不便，为此，综合集成多项成熟先进的测试软硬件技术，设计出该型直升机继电器盒的自动测试设备，实现了对继电器盒各逻辑功能部件的逻辑功能准确无误的测试及故障定位。
