Development And Application Of Two-Ticket Expert System Inference Engine

Thermal power is the main form of energy supply in china at present,The "two-ticket" system of work tickets and operation tickets is an important system to ensure the safe operation of thermal power plants,Employee's skill level of "two-ticket" is not only directly affects the safety of thermal power plant production,but also related to the thermal power plant production efficiency.In this context,a two-Ticket expert system is an effective way to improve the accuracy of work tickets issued by employees.This paper's main research object is two-Ticket expert system inference engine.First of all,Briefly analyzes the composition and working principle of expert system and the application of expert system in the field of two-Ticket of thermal power plant in China.Then,Proposed the development target of two-Ticket expert system inference engine.Then,Analyzes the structural characteristics of the core information in the actual filling process of "two Ticket",The two tickets' key information can be broken down into equipment name words,action words and status words Using HTML,JS technology to draw all kinds of tickets' basic template,and the ticket attributes fixed on the ticket basic template,Divide the actual ticket into the ticket basic template and ticket data.Proposed a new form of storage for expert system knowledge of two ticket,Constructed the two-ticket Chinese word segmentation dictionary.Finally,Established the knowledge base of two ticket expert system.Then the construction and working principle of inference engine in expert system are analyzed,including the reasoning direction and control strategy of inference engine,the problems and countermeasures in inference engine design are discussed,The reasoning method and control strategy of two-ticket expert system inference engine are determined,And completed the inference process design of Chinese parser and inference engine based on Lucene Chinese word segmentation inference engine.Finally,combined the above research results,completed the project realization of two-ticket expert system based on B / S structure,and applied the project in the power plant for practical test.
