Ammunition Works Vxi-based Test System Integration

The criterion of VXIbus is developed based on VME bus and GPIB bus. It integrates the advantages of the two kinds of data bus. For this reason, it has been widely used in the fields of space flight, ship industry, electronics and war industry. Otherwise, the VXIbus instrumentation has powerful ability of function integrating. Now, it is clear to see that the VXIbus instrumentation is very suitable for designing moderate and large scales, high precision auto control system and test system.In the test process of ammunition development, the parameters in ammunition field generally are explosion shock wave, medium pressure, medium acceleration, instantaneous temperature and medium strain etc. They are dynamic signals that have the characteristics of high shock, high frequency response, high load and high temperature. Thus, the test system must be a universal system that has multiple channels, high precision and is suitable for capturing instantaneous signals; on the other hand, the system also must be set up easily and quickly.According to the characteristics of ammunition engineering parameters, the thesis demonstrates the feasibility and advantages that set up system by VXIbus instrumentation in detail. It also introduces the system structure and how to choose the VXI module, how to implement the integration of test software according to VPP and the methods of signal processing. At last, the test system was proved to be a suitable system in ammunition testing field by experiments.
