The Intelligent System Of Water Supply

Aiming at the problems of less monitoring terminals,single source of data,low timeliness of warning,low degree of intelligent equipment and low utilization of data,a set of Intelligent water supply system is designed in this thesis.The system realizes the running status of urban water supply and drainage system through data collection,data transmission and data analysis,realizes the real-time monitoring and early warning of the pipe network by using data mining and visualization interface,eventually.And studied the application of data modeling in the informatization and intelligence of "urban water system"In this thesis,the intelligent water supply system mainly contains five modules by designed :intelligent connector,data server,generic transfer protocol,business designer,data display platform.The main research of the working principle of each component of intelligent water supply system and the methods of working together between modules.The main work of the dissertation is as follows:(1)The smart connector is designed by RTOS + VFS + script system,which is responsible for data acquisition sublayer and sensor network management and collaborative information processing sublayer.It has the advantages of good universality,high integration and high intelligence,and the advantages of self-check and lightweight machine learning function.(2)Designed to interact with the smart connector data server,and designed a high-concurrency communication framework.The data server is responsible for interacting with the smart connector for data storage management as well as for data analysis and data modeling.Data server design is divided into the link layer,transport layer,session layer,service layer,application layer.The link layer abstracts the data link,and specify different data sources according to different application scenarios.The transport layer supports four communication states,covering reliability communication CON,broadcast communication NON,bus reset signal RESET,and acknowledgment ACK.Protocol can meet the communication needs of various scenarios.Transport layer also has congestion control and flow control functions to meet the communication needs in different bandwidth,different network conditions,different processing capabilities of the terminal.It design a business process engine plug-in based on dynamic compilation technology,it is mainly for the purpose of converting the collected raw data into the data needed to display the business in the foreground.The main features of this engine are to support the dynamic expansion and the customization of the business.(3)It designed a business designer about background management.It is mainly responsible for business design authority,menu design,site and device design,sensor-related design of sub-sensor network,map configuration.(4)It designed a business display platform for water supply system business display and front-end alarm push.(5)Studied the application of data model in water affairs and designed data warehouse.The database table in the data warehouse is a one-to-one correspondence of the waterworks display business.By collecting and analyzing the original raw data,it is finally converted into the data items of the business to reduce foreground data processing and increase the efficiency.The data warehouse is also responsible for storing the data about the data model required for data modeling.The system analyzes and processes massive water affairs information in time.Through the linkage with intelligent connectors to achieve urban pipe network intelligence.Based on the corresponding data model,the system can reduce energy consumption,optimize production,early warning intelligently and improve operational efficiency by analyzing the production model,operational model,so as to achieve the "wisdom" of the state,with good prospects for the application.
