【摘要】 基于虚拟仪器技术,开发了柴油发动机信号处理系统,该系统数据采集由传感器与PCI-6023E数据采集卡完成,系统软件采用LABVIEW6.0,根据柴油发动机的典型故障,对系统参数赋值,利用BP神经网络对采集的数据进行处理,进而判断发动机的故障,试验表明该系统是可行的。更多还原

【Abstract】 Based on virtual instrument technology, the fault diagnosis system for diesel engine was developed. Its digital treatment system was consisted of sensors and PCI-6023E collectors, its design software was LABVIEW6. 0. This system character parameters were defined by engine’s typical faults. In this system, the collected data were treated with BP neural network to diagnose engine’s faults. The tested results show that this system is feasiable. 2 tabs, 6 figs, 9 refs.更多还原
