Based On The Projectile Dynamic Parameters Of The Vxi Bus Test System Integration

The VXI bus is formed by the high speed computer VMEbus extension to instrument field. The VXI instrument is the combination product of computer software technology and test technology. It is especially suitable for designing moderate and large scales auto test and measurement system or it is required for high speed and more accuracy.The basic signals in the projectile test are dynamic signals such as high initial speed, high chamber pressure, high frequency response, high impact, high temperature measurand. So, the test and measurement system should have more channels, the signals are easy to be obtained, and no matter the measurand it is, the test and measurement plateau should be integrated instantly.In order to satisfy the requirement above, we integrate VXIbus projectile dynamic parameter test and measurement virtual instrument plateau with VXI modules in this paper. The system includes data acquire and time parameter measurement. We give the hardware platform project, explaining the Vpp Specification in software integration. Besides source code, we provide the block map and soft panel of data acquire, signal analysis and processing, time measurement software. The system err is analyzed. The system is examined by using the system to measure the parameter of the projectile blast wave. It is proved to be good result for precision, reliability and other aspects.
