The paper studied and constructed an expert system for vibration fault diagnosis in large steam turbine generator set, and briefly described the structure and function of various components of the expert system, detailed described the knowledge database and inference machine. In this expert system, the knowledge database built on production rule, and the inference machine based on confidence. Finally,...
The failure knowledge of hydraulic component was expatiated based on the object-oriented method in this paper, and established a failure knowledge database. A fault reasoning strategy was defined, and given a detailed explanation of failure reasoning process, according to characteristics of directed tree and failure knowledge. A fault diagnosis expert system for hydraulic components was developed,...
Diagnosis of hydrocephalus symptoms and shunting system faults currently are based on clinical observation, monitoring of cranial growth, transfontanelle pressure, imaging techniques and, on occasion, studies of cerebrospinal fluid (CSF) dynamics. Up to date, the patient has to visit the hospital or meet consultant to diagnose the symptoms that occur due to rising of intracranial pressure or any shunt...
Based on Internet and using artificial intelligence techniques to guild remote fault diagnosis expert system can provide expert-level fault diagnosis service for remote devices. Based on the introduction of general structure and related key techniques of fault diagnosis system, the expert system was introduced into fault diagnosis system in this paper. The architecture of an open fault diagnosis expert...

To fulfill the complexity of agriculture disease problem, fuzzy reasoning method is presented in agriculture disease diagnosis expert system; both positive and negative effects of disease symptoms on diagnosis results have been considered; weighed Euclidean distance method is introduced to calculate the comparability; effective diagnosis results and reliabilities are given out. Finally, a case study...
Expert system is widely used in fault diagnosis, but how to obtain knowledge is a bottleneck restricting its development. Data contains rich information about the machine, and acquiring knowledge from it or data mining in other words is considered as an effective way solving this problem. An algorithm based on rough set and genetic algorithm for feature reduction is proposed in this paper. Minimal...
