Research On The Evaluation Of Smart Sponge City Monitoring And Control System

In recent years,with the integration and implementation of the Intermet of Things,big data and other information technology and the sponge city construction project,it has brought new opportunities for the development of the sponge city.The intelligent sponge city monitoring and control system is the product of the Internet of Things+sponge city.Through the analysis of the basic theories related to the intelligent sponge city monitoring and control system,combined with the domestic and foreign sponge city,smart city management system,smart water management system,intelligent sponge city monitoring and control system and other development status and research status,looking for wisdom The evaluation index of the sponge city monitoring and control system evaluates the intelligent sponge city monitoring and control system to find out what needs to be improved,and provides reference for the development and implementation of the intelligent sponge city monitoring and control system.Based on the theory of system engineering,the concept,connotation and characteristics of the intelligent sponge city monitoring and control system are analyzed with the overall concept.The evaluation direction of the intelligent sponge city monitoring and control system is analyzed from the perspective of system users.According to the selection principle of evaluation indicators,literature research The expert research method and other methods initially constructed the evaluation index system,and designed the "Intelligent Sponge City Monitoring and Control System Evaluation Index Importance Questionnaire,to conduct a wide-ranging expert questionnaire survey,statistical analysis results,and analysis of the initially established indicator system utilization factor.Correlation analysis to screen,integrate and adjust to form the final target of intelligent sponge city monitoring and control system evaluation,professional data management?sponge city facility management?collaborative platform management?social benefit managementi four control layers,data collection management Indicator system of 9 indicator layers such as participant management,platform framework setting,sensor coverage,heterogeneous data fusion,and annual indicator flow control efficiency.By analyzing fuzzy comprehensive evaluation methods grey correlation degree method?comparative analysis method?data envelopment analysis method(DEA method)?analytic hierarchy analysis method and other comprehensive evaluation methods and weight calculation methods,advantages and disadvantages,due to intelligent sponge city monitoring In the evaluation of management and control system,some information is difficult to quantify and the characteristics of evaluation criteria are diversified.The analytic hierarchy process combined with Super Decisions software is used to determine the weight of evaluation index of intelligent sponge city monitoring and control system,and the weight calculation results are analyzed to obtain fuzzy comprehensive evaluation method.Evaluation of the intelligent sponge city monitoring and control system.At the same time,for the partial evaluation indicators,the design of the indicator scales of qualitative and quantitative indicators was carried out to help the experts to score and judge.In order to verify the applicability of the evaluation method and evaluation index,a case of intelligent city sponge monitoring and control system in a city is taken as an example,and the case is calculated by fuzzy comprehensive evaluation method.The comprehensive evaluation result is better.This is mainly due to the development and maturity of a series of monitoring instruments such as flow sensors,rain sensors,SS online monitors,etc.,making data collection more convenient and accurate,but still lacks uniform data interaction standards,but also exposed The rainwater management model has different standards in different places,and the applicability needs to be strengthened.Whether the permission setting is scientific will largely hinder the precipitation and circulation of knowledge;the intelligent sponge city monitoring and control system and related education departments and social associations?organizations,etc.There are still some problems with the docking.In view of the above problems,it is proposed to increase hardware investment,establish a unified data interaction standard;strengthen the scheduling capability of cross-basin govermance;enhance functional allocation in authority setting,strengthen knowledge circulation;strengthen the development of upstrean and downstream industry chain and acti-vely cooperate with the government The function of docking by relevant departments forms effective social management benefits.
