Abstract:

In order to solve the problem of a certain type of aircraft power supply system of air-to-ship missile large current and full load capacity can not be detected,an air-to-ship missile power supply system detector was developed;automatic control technology is adopted to build a high power load network,effectively solve the simulation problem of large start current with narrow width;using graphical programming technology,state machine technique,DMA FIFO and TCP/IP technology,the state control and the real-time transmission of data acquisition between the sensor and the touch screen computer have been effectively realized,experimental result prove,this detector can effectively diagnosis and locate the fault of the air-to-ship missile power supply system,the relative error of voltage detection is less than ±1.5%,and the relative error of current detection is less than ±1%,and its performance index reaches the design requirement. The research has certain practicability and wide application prospect.
