Abstract: Aimed at huge systems and difficult fault diagnosis of some large weapon equipments, a scheme of on?line monitoring and fault diagnosis based on wireless telemetry technique was presented in this paper. Each test instrument is fixed directly on the equipment and communicates signal and command with a host computer wire?lessly .In this way, cable connections between the host computer and test instruments are greatly reduced, and then the diagnostic system can be portable and miniature. Combined multilevel distributing measurement and single-board multi-chip technology, high speed acquisition of test signal was implemented. Auto-search and on?line monitoring of working state of the equipment were actualized by use of pattern recognition and neural net?work technologies. Experiment results show that this system can implement expeditious and accurate fault posi?tioning and long-range monitoring for large weapon equipments.
