基于专家系统的导弹自动测试与故障诊断系统研究

Study of Automatic Test and Fault Diagnosis System for Missile Based on Expert System

基于虚拟仪器技术和专家系统的导弹自动化测试与故障诊断系统,采用模块化仪器总线标准—PXI,集PXI卡式仪器、程控仪器和各种先进的测试诊断技术于一体,是一套具有自动性能测试和故障诊断的综合测试系统。利用专家系统,大大提高了系统检测的智能化和自动化程度。用于导弹武器系统中电子装备的通用参数测量、专项性能指标测试、功能测试及故障诊断,可以将故障定位到电路板。实践表明,系统适用于多种不同型号导弹的性能测试、故障诊断与维修。

The PXI bus is used in the automatic test and fault diagnosis system for missile that is based on virtual instrument technology and expert system. It includes some PXI module instruments, programmable instruments and other advanced test techniques. It is a composite test system that has automatic performance test and fault diagnosis capability. From using an expert system, the intelligence and automation degree of the system is enhanced greatly. It can be used to test the current parameters, special capability and the function of electronic parts among the missile weapon system. The faults can be demarcated on the circuit cards. The practices indicate that the system fits for the performance measurement, fault-diagnlosis and maintenance of many different missile weapon equipments.
