【摘要】 利用虚拟仪器技术成功开发了一种发动机故障诊断仪器 ,具有数字万用表和示波器的双重功能 ,能连续检测、记录、显示和存储汽油机 (电喷式或化油器式 )点火系统、起动系统、各种传感器、执行器及柴油机供油系统等零部件的电子波形、相关参数 ;配有神经网络专家系统 ,在显示波形的同时 ,直接给出诊断结果即指示故障部件并说明原因 ,因而是一种理想的汽车在线故障诊断工具更多还原

【Abstract】 An automobile default diagnosis instrument is successfully built by means of technology of virtual instrument and artificial neural networks.It has double functions of digital multimeter and automobile oscilloscope,may continuously check,record,display and store electric wave of automobile(with EGFI system or carburetor)electric or electronic part such as sensor,transducer or performer,etc.Installed in neural networks expert system,the instrument may directly give diagnosis result i.e.indicate automotive default part and explain its corresponding reason while displaying electric wave,so is a kind of idealistic automotive on line default diagnosis tool.更多还原
