Design, Multi-parametric Test System Based On Usb Interface Artillery

Test of artillery's dynamic multi-parameters is of far-reaching importance in the design, development, production and acceptance process of artillery. Modern test of artillery's dynamic multi-parameters has the characters as execrable surroundings, much disturbance and so on. So an integrated test system of artillery's multi-parameters based on the interface of USB is built in the dissertation.The artillery dynamic test system of multi-parameters includes hardware system and software system. ARM9 which is one 32-bit MPU is the core in the hardware system. Considering the portable ability, function, reliability, cost, cubage, power consumer and so on, the dissertation builds the data acquisition system based on the interface of USB. Based on the analysis of the dynamic parameters' characters, the dissertation separately chooses the sensors and corresponding conditioners which have the high ratio of performance to price and high reliability. Also the dissertation solves the problems of each parameter occurred in the test. The software system chooses the modularized design. And each parameter has its corresponding interface. The software system has the function of parameter setting, data processing, waveform display, print and help based on the Labview software.The result shows that not only has the integrated dynamic test system of multi-parameters satisfies the requirement of practical test, but also the building of hardware is reasonable and high ratio of performance to price. The software system has good man-machine conversation interface. And it meets with the operation custom of shooting-range's personnel.
