APPLICATION OF DISTRIBUTED INTERACTIVE VXI SYSTEM IN WEAPON SYSTEM TESTING AND DIAGNOSING

摘要

Modern weapon systems are more intelligent and roboticized, and require more efficiency for the weapon's test and diagnosis. A VXI-bus based distributed interactive automatic test and diagnosis system of weapon system, which can test the large weapons real time and parallel, is introduced in this paper. Various VXI & GPIB instrument can communicate with the interface of VXI & GPIB bus in this system, via VISA (Visual Instrument Standard Architecture) application programming interface. This system has a better ability of anti-disturb and enduring bad-condition, by compare of traditional test system. Various test nodes communicate by the way of distributed interactive interface, that is all nodes have a public communication adapter, DIS-link, through which data communicate by user defined test PDU (Protocol Data Unit). This distributed interactive test network has a loose architecture, which means the test node can be used by oneself or by multi-test nodes without any modification of hardware or software. In a word, this system has better parallel process ability, and more patulous ability, which can combine various test systems. Introducing of the system provide a way of exploring the improvement the weapon testing and diagnosing not only for the missiles, but also for other weapons.
