Application Research Of Drainage Facility Supervision And Maintenance System Based On MongoDB

In the development of the wave of urban smart construction,urban water affairs departments rely on Internet of Things technology,information communication technology and computer technology,and have always regarded the online supervision of drainage facilities and the inspection and maintenance of facilities as their top priorities.At this stage,the water affairs department is based on the drainage facilities,and realizes the normal operation of the drainage facilities through the daily inspection and maintenance of the maintenance unit.Inspectors collect and record the problems of drainage facilities by patrolling and shooting the drainage facilities.However,with the increase of drainage facilities and the expansion of inspection areas,the water affairs department urgently needs to establish a drainage facility maintenance and supervision platform.Relying on technologies such as big data storage and management,big data compression algorithms,remote video monitoring and complex data classification and query,it proposes more efficient solutions for urban smart drainage and facility supervision.This article combines the advantages of Mongo DB and Node.js to build a drainage facility maintenance and supervision platform for the first time in China.The main work of the thesis is as follows:(1)The application scenarios and business requirements of urban drainage informatization are studied,and the data characteristics of drainage business data are analyzed.Designed the library table structure of Mongo DB database.Aiming at the storage and management of big data,the Mongo DB database distributed cluster was designed and implemented,which improved system performance and enhanced data reliability and service availability.In addition,in view of the characteristics of rain data,a revolving door compression algorithm is used to compress the data.Using the Grid FS file storage module in Mongo DB data,a distributed attachment storage server cluster based on Grid FS is designed and implemented to store and manage multimedia data.(2)Researched the application development of Node.js combined with Mongo DB.Based on the characteristics of both Mongo DB and Node.js,the server-side development based on Node.js was carried out,and the operation interface to the Mongo DB database was realized;various functional modules of the server-side were designed and realized.Designed and implemented the client interface.The designed and implemented Shanghai drainage facility supervision and maintenance system has been tested and put into operation in June 2019.The operation is stable,meets business needs,and improves the efficiency of urban drainage facility supervision and maintenance.
