Projectile Gun Module Of Vxi Bus-based Study

At present, in the weapon test field of china, some pivotal testing items have itsown particularities. And it is also difficult to buy the VⅪbus modules correspondingto the test instruments at home or even abroad. Consequently, in order to meet thedemands of scientific research and developing in weapon testing, popularize thecorresponding VⅪbus module, and reduce the cost, we are expected to resolve theproblems existing in the research on these modules. According to that, this paper isaimed at the development of bullet speed test and measurement module based onVⅪbus, which can be the same with lots of target installation and several kinds ofbullet.The principle and method of bullet speed test and measurement are analyzedfirst. The principle and development of all kinds of target installation and speedtesting instrumentation are summarized, a method of statistic speed of canister isadvanced, according to particularity of canister; VⅪtechniques are analyzed. Thehardware platform and software framework are generalized and specified, adesigning plan is put forward. Based on this plan, this paper designs functioncircuit,VⅪbus register-based interface circuit of speed test module and The lastpart of the paper mentions the analysis and study of the IⅥmodel of the VPPinstrument driver. Applied software exploit platform Labwindows/CⅥcompiled andprogrammed the driver based on IⅥmode of bullet speed test and measurementmodule and designed the softpanel.The simulation testing shows that the module of bullet speed based on VⅪbusdeveloped successfully. The design principle and realization method of bullet speedbased on VⅪbus are accurate and feasible; The design of register-based interfacecircuit based on VⅪbus accords with the criterion of VⅪbus and the circuit isall-purpose. The hardware circuit of speed test and measurement module is designedwonderfully.
