Research On Intelligent Operation And Maintenance Of Water Supply Pipe Network Based On Bim And Internet Of Things

The healthy operation of the municipal water supply pipe network is the basis for ensuring the safety of the urban underground pipe network.Any problems in the water supply process may bring safety hazards to the lives of urban residents.At present,the water supply pipe network system in most cities has a low level of operation and maintenance and serious waste of water resources.In order to ensure the safe and efficient operation of the water supply network,the research on the intelligent operation and maintenance of the water supply network is imperative.Taking the water supply system in the campus of H school as the research object,aiming at the instability of the operation of the water supply system,from the visualization of the BIM model of the water supply system in the campus based on the B/S framework,to the data collection and analysis of the IOT in the water supply area,The FLUENT software is used to analyze the fluctuation of the pressure data of the most unfavorable point in the water supply area.Finally,the fourth part of the intelligent operation and maintenance platform of the water supply network is used to study the intelligent operation and maintenance of the water supply network.Through the establishment of the water supply pipe network and pump station BIM model,the equipment fault rapid positioning and intuitive visual management,using NB-IOT module to collect real-time pressure and flow data of the water pipe network and pump station operation and maintenance,rapid analysis and evaluation The operation status of the water pipe network solves the problems of abnormal water supply pressure and pipeline leakage.Through the FLUENT software,the most unfavorable point pressure data of each water supply area is analyzed,and the most unfavorable point pressure fluctuation reason is found,and a solution is proposed.The water supply pipe network intelligent operation and maintenance platform is initially established to reduce the operation cost of the water supply pipe network and avoid water waste.It mainly includes the following innovations:(1)The application of the lightweight research results of the BIM model of the water supply network on campus in the project provides innovative technical support for the operation and maintenance management platform under the B/S framework.(2)NB-IOT-based wireless interconnection sensing technology realizes real-time collection of pressure and flow information and device status monitoring to achieve more targeted and scientific dynamic management.(3)Put forward the hypothesis for the cause of the most unfavorable pressure fluctuation problem in the water supply area.The FLUENT software is used to simulate the internal fluid dynamics of the pipeline to accurately analyze the root cause of pressure fluctuation.The research on the intelligent operation and maintenance of the water supply system on the campus provides technical support for the intelligent operation and maintenance of the water supply network,and provides practical application value for the normal operation of the urban water supply network and social public safety,and further accelerates the advancement of urban water supply to intelligent management.
