Design And Application Of Operation And Maintenance Information System Of Centralized Control Of Hydropower Stations

With the development and application of information technology and multimedia technology,the way in which people work and study has undergone tremendous changes.Online work,online learning and other network approach came into being and the emergence of intelligent terminals made online activities more convenient.In order to adapt to this change,combined with their own needs,enterprises began to develop their own information system.Operation and maintenance work of hydropower stations(referred to as "operation and maintenance")security has always been the focus of national and social concern.At present,most hydropower stations in China have developed a system to monitor the operation of hydropower stations,which has an early warning effect on the operation and maintenance work of hydropower stations,but can not guarantee the full range tracking of field operations and the expert assistance.How to take effective measures to assist the personal operation and maintenance work,has been a new problem that the entire power industry needs to explore.Through the field investigation of one centralized control hydropower stations,combined with the theoretical knowledge of system design and cloud service,this paper aims to design a Operation and Maintenance Information System of Centralized Control of Hydropower Stations,focusing on the way of work and learning training of the operation and maintenance personnel,which is regarded as the research object,The following is the main research.First of all,this paper analyzes the current situation of the operation and maintenance work of some hydropower stations,and analyzes the system function,business process and database according to the research and interview.This provides the basis for the design of operation and maintenance information system.Secondly,this paper constructs the basic model of the operation and maintenance information system according to the demand analysis,and puts forward the overall framework of the operation and maintenance information system according to the hierarchical logic structure.According to the functional requirements and business process,the system are divided into six subsystems and the 16 main function modules under the six subsystems,such as resource addition,remote collaboration,learning recommendation,proposal improvement,resource search and information management.With the design of the function,design concept model and two-dimensional relational database table of the database of the system.Then,this paper builds the content-based personalized service recommendation model of the label.In this paper,we propose a method that named "Expert Service" for dealing with non-document file compared with TF-IDF(keyword weight)method for document file.The paper uses cosine similarity algorithm to realize resource matching to meet the personalized service recommended demand of work and study training.In addition,according to the design of operation and maintenance information system and the basic situation of the centralized control hydropower stations,the main function of the system is developed by computer technology.The main development is the front-end development for the desktop side and the mobile terminal front.The implementation of the system can validates the proposed recommendation algorithm and the expert service method.The realization of the system provides a new idea,the full range tracking of field operations and the expert assistance,for the operation and maintenance work of centralized control of hydropower stations,and has a certain exploration significance.Finally,the achievement of this paper is summarized,and the preliminary research work is proposed.
