Implementation Of Mobile Terminal Assistant System For Inspection Of Thermal Power Plant Based On Optimization Of Text Retrieval Model

The power industry plays an increasingly important role in modern society as a pillar energy industry in promoting social progress and economic development.Good operating condition of equipment,implementation of accident prevention,reasonable operation mode of power system are 3 necessary conditions of the reliability of power supply.Therefore,the inspection of equipment is an indispensable work for operators.With periodic inspection,operators can find potential problems to eliminate risks,which is the basic way to keep normal operation of the power system.Under above conditions,this paper set up a mobile terminal system for inspection of thermal power plant in order to improve the work efficiency of employees.With our system,users can gain knowledge refers from equipment principles to standard parameters,which can help workers to improve the quality of their work.Main contents of my paper are as follows.(1)This paper collated and analyzed the daily work of inspectors in thermal power plants in order to find out the defective points and determine the corresponding internet solutions.(2)The text retrieval model BM25 has been optimized and used to reconstruct the similarity ranking function of open source framework Lucene.The effect of the new model has been verified through the recall accuracy rate and MAP test index.The crawler grabbed book information from internet as original material of our database.The search module was developed by finishing 3 steps of work,such as building tokenizer,indexing and coding searching function,which has been encapsulated to facilitate the mobile terminal.(3)This paper completed the SSL configuration for HTTP server Nginx and released the functional ports.The CMS set up through Wordpress,the output interface of which has been developed for mobile terminal to call.(4)Our project completed the Mini Program development of client software and embedded key data points,which could feedback operating data of users.Connection between system feedback module and WeChat customer service platform has been built.(5)Our system has been formally launched after functional test and usability research.The development of our system has great practical significance,which helps inspectors not only reduce their inspection slip but also improve their professional skills and work efficiency.
