Development And Application Of Online Monitoring System For Operating Parameters Of Urban Sewage Pipe Network In Jinan City

The drainage pipe network is the core of the urban drainage system and an important prerequisite for ensuring the stability and rapid development of the city.This study takes the urban sewage pipe network of the main urban area of Jinan as the research object,and conducts research and development on the online monitoring system of sewage pipe network operation parameters,and applies it to the daily management and planning construction of the sewage pipe network.According to the development trend of urban drainage informationization at home and abroad,this paper combines the current situation and future planning of drainage facilities in Jinan City,and analyzes the online monitoring needs of the drainage network.Based on it,according to the principle and requirements of the optimized layout of monitoring points,the research determines the optimal layout of the online monitoring points of the operating parameters of the sewage pipe network in the main urban area of Jinan City,and combines the current water environment of black odor water treatment and sponge city construction in Jinan City.Governance work needs and determine the first phase of the project construction plan.Through the selection test of different manufacturers and models of flow and liquid level monitoring equipment,the performance indexes of monitoring equipment of different manufacturers were compared and analyzed,and the online monitoring equipment suitable for Jinan sewage pipe network environment was determined.Based on this,the existing drainage information platform resources are fully utilized,and the overall structure of the on-line monitoring system for operating parameters of sewage pipe network is constructed by comprehensively utilizing Internet of Things,wireless acquisition and GIS technology.Based on the Internet of Things technology,the system design and development of the application software for the on-line monitoring system of the sewage pipe network operation system has realized the real-time monitoring of the pipeline flow and liquid level of the sewage pipe network in the main urban area and the key pipe network nodes,and The functions of monitoring,statistical data and abnormal monitoring data alarms such as flow and liquid level of different monitoring points have laid a foundation for the auxiliary decision-making applications such as routine maintenance,optimized operation and planning construction of sewage pipe network.Based on the real-time monitoring data obtained from the on-line monitoring system of urban sewage pipe network operation parameters,the data of flow,liquid level and other data of different monitoring points are statistically analyzed,and the pipe network operation under different time periods,different seasons and different statistical methods is established.The curve analyzes and evaluates the operation status of the sewage pipe network in the monitoring area,and applies the analysis and evaluation results to the management decisions such as routine maintenance,optimization operation and planning construction of the drainage pipe network system.Based on the current research results,the following suggestions for improving the system construction are proposed.This paper will play a positive guiding role in the construction of the on-line monitoring system for drainage networks at home and abroad,and has certain reference significance.
