【Abstract】 In order to improve the measuring accuracy and efficiency of projectiles’ static parameters, and to calculate and save the measured result automatically, it is introduced in detail that the design of a software system for measuring projectiles ’ static multi- parameter based on VXI in the paper. VXI-bus was adopted to realize multi-serial opening communication and to collect measured data from the underlying instrument such as grating ruler, pressure sensors, pulse counters and to control the underlying moving parts. All collected data were disposed and calculated by computer and the various static parameters of projectiles were obtained quickly and accurately, all measured results were saved for the later filing and querying. The given tests showed that the measuring time was greatly reduced and the measuring accuracy was substantial increased when the software system was applied to measure the same projectiles, The function of software system based on standardized software operating environment is power, operation is easy, running is steady and it has extensive appliance and exploition foreground.更多还原
