Abstract: The realization of hardware and software technology of remote distributed Characteristic Measurement system for missile that based on RS-485 bus and USB bus technology is introduced. The merits of the two buses can be exploited sufficiently in the system, which can realize the signal acquisition and transmission functions of high-speed, long-distance and multi-channel. The reliability of the system is good and the whole-capability is stable when it is used to test the performance of missile in the formidable natural conditions.
Key words: RS-485 bus; USB bus; performance measurement; virtual instrument
