This equipment is a portable , economical , practical , small desktop test bed vehicle electrical omnipotent , and can be adjusted without disassembly of the various auto electrical equipment and instrumentation , but also the electrical and automotive engine fault diagnosis 本设备是一种便携式,经济实用的小型台式汽车电器万能试验台,可以不解体检测和调整汽车的各种电器设备和仪表,也可对汽车电器和发动机的故障进行诊断。
This method of diesel engine fault diagnosis is feasible theoretically . while the fault diagnosis system using this method is rare , just because the crankshaft instantaneous angular acceleration measurement is demanding , such as , good frequency response , high precision 这种柴油机故障诊断的方法在理论上是可行的,但目前这种成型的系统不多,究其原因是测量曲轴的瞬时角加速度需要系统具有良好的频率响应特性与高精度。
The research of this paper is based on the latest research of neural network and fuzzy theory to resolve internal combustion engine thermal process intelligence fault diagnosis . the major research contents are as follows . first , the state of art internal combustion engine fault diagnosis both at home and abroad has been summarized , and the existing problems have been pointed out 本文的研究是在神经网络与模糊理论最新研究基础上,围绕着内燃机热工故障智能化诊断问题展开的,主要工作如下:首先,综合分析了国内外关于内燃机故障诊断方面研究现状,指出了存在的问题。
The reason , purpose , contents and practical meanings of the subject have first discussed briefly . after analyzing several popular diagnosis methods which are often used in the process of diesel engine fault diagnosis , we point out the exist problems about fault diagnosis and possible development . the technologies , such as signal collection and processing , artificial intelligence , are also depicted in brief 论文首先对课题的来源、研究的内容、目的、实践意义进行简要的论述,分析了在内燃机故障诊断过程中所采用的几种常用诊断方法,指出目前故障诊断存在的问题以及将来的发展,并对信号的采集与处理、人工智能等技术作了简单的阐述。
In order to diagnose complex system , because there exists too many characteristic parameters , the problems , such as over - large scale of neural network , unduly long train time , and redundant rules in expert system ' s rule base , will result in the reduction of whole system ' s practical performance . then the rough set theory that received focus attention in recent years is led into the internal - combustion engine fault diagnosis work . the application of this theory in the attributable optimization of fault diagnosis characteristic parameters is explored 考虑到在对复杂系统进行诊断时,由于特征参数过多而造成神经网络规模过大、训练时间过长以及专家系统规则库存在规则冗余等问题,最终导致整个系统实用性能的降低,为此将粗糙集理论引入了内燃机故障诊断工作,对其在故障诊断特征参数属性优化中的运用进行了探索。
