基于虚拟仪器的某型装备故障诊断系统设计

为了改变依靠传统的人工故障检测、分析手段进行检测维修效率低的现状,利用虚拟仪器技术与专家系统技术,设计实现了一个针对某型通信装备的故障诊断系统。该系统利用装备的自检功能进行板级故障定位,再利用虚拟仪器检测电路关键部位的电气参数作为故障信息,通过专家系统对故障信息进行分析处理后将故障定位到电路板的元器件级。该系统还通过网络连接为用户提供了专家远程辅助诊断功能,降低了对维修人员的技术要求,提高了故障定位的效率和准确率。

Design of Fault Diagnosis System for Certain Equipment Based on Virtual Instrument

To change the current situation of low detecting and maintaining efficiency in way of traditional manual fault detection and analysis,a fault diagnosis system is designed and realized by using the virtual instrument technology and the expert system technology according to certain communication equipment.The system locates the faults at the board level by using the self check function of the equipment and detects the electric parameters as the fault information at the key parts of the circuit using the virtu...
