Application of Virtual Instrument Technology in General Test System of Launcher

To detect the operating state of temperature-regulating control system of launcher, a new method for designing general test system is discussed. The test system adopted virtual instrument technology, its data exchange between equipment and industry computer was conducted via VXI bus technology, and software in LabWindows/CVI environment was developed to achieve the tasks of data acquisition, data disposal, testing the procedure of adjusting temperature and simulating the display combination. The functions of proposed test system can not only check the hardware malfunction of temperature-regulating system, but also do a perfect evaluation for control software.
