Abstract:

In order to meet the testing requirement of launch vehicle telemetry system,while increasing the flexibility of the test equipment,reducing the development costs,a simple and efficient automatic test platform of the telemetry system based on signal is designed. The test platform is developed based on PXI bus,by the combination of multiplexing switches and I/O module,the platform can be used to realize inspection testing and concurrent testing for multiple parameters,which makes the platform have good versatility and flexibility,it can be applicable to multiple launch vehicle without changing the hardware,while significantly reducing the development costs. By receiving and resolving the telemetry data of launch vehicle,it truly forms a automatic system to test and verdict automatically,without human intervention during the testing process. Through experimental verification,the test platform is stable and can satisfy multiple launch vehicle telemetry system integration testing needs,It also provides a new designing thoughts of this kind of test equipment.
