Abstract:

For the testing demands of altitude sensor, an auto-test system has been designed which can automatically test different kinds of altitude sensors. The system built standardization and modularization hardware platform with many bus instrument of multi-channels such as CPCI, GPIB, RS-232 and Ethernet, designed hierarchy and open software bottom structure with technologies such as DLL, ActiveX, COM, developed application program under VC++ IDE environment which has the characteristics of convenient integration and configuration. The system can test all indexes, and applies successfully. The system calibration ensured the reliability of testing result and the using efficiency of the test system, and the auto-test and parallel-test technology enhanced servicing efficiency and reduces servicing cost, and the design principle of universalization and expansibility resulted to conveniently extend tests for other homologous altitude sensor.
