1. System overview The
urban water supply network is the infrastructure and the facility that the city depends on for survival. Therefore, the online water quality monitoring system of urban water supply pipe network is very important, real-time monitoring of water supply pipe network transmission and terminal water quality data. When abnormal data is monitored, the water plant, water pumping station and water affairs bureau shall be fed back for diagnosis and treatment at the first time, so as to improve maintenance efficiency, reduce losses, ensure the quality of water and water supply, achieve scientific prediction, reduce costs, and improve The purpose of efficiency is to ensure stable water supply and safe water quality. The online monitoring system of the water supply pipe network provided is a set of real-time stable and effective technical solutions developed in response to the characteristics and requirements of the aforementioned urban water supply.
2. Demand analysis.
Pipe bursting problem: Pipe bursting is a major hidden danger to the safety of urban water supply. The continuous bursting of pipes, especially the extra-large bursting pipes, poses a great threat to safe water supply, and the economic loss is severe. The social impact is bad, and it may cause personnel in severe cases. casualties.
Secondary pollution of the water quality of the pipe network: At present, the water quality of the factory water in my country’s water plants has been basically controlled within the national drinking water sanitation standards, but the water quality is affected by the pipeline transmission and distribution and secondary water supply facilities, and the pipe network has become a way to improve the water quality of the water supply. Bottleneck.
Pipe network leakage and waste of resources: The pipeline has been running for a long time or is damaged by the outside world, causing different degrees of pipe network leakage, which not only wastes valuable water resources, but also affects the economic benefits of the water supply industry.
The dispatching ability is relatively weak: the operation of water plants and booster pumping stations relies too much on manpower, and even part of the water supply still relies on manual operation. It is difficult to dispatch and control the overall pipeline network.
3. System principle The
monitoring water supply pipe network system is a set of online monitoring equipment as the core, using modern Internet of Things technology, through special analysis software. A comprehensive monitoring and management system for real-time and rapid collection, storage, processing, query, reporting, and early warning of water quality, pressure and flow monitoring information of the tap water pipe network. The water supply network monitoring system is suitable for water supply companies to remotely monitor the water supply network. The staff can remotely monitor the pressure and flow of the city's water supply network at the Water Division Dispatching Center. Scientifically command the start and stop of water supply equipment in various water plants, ensure the balance of water supply pressure and stable flow, and timely detect and predict the occurrence of pipe burst accidents.
4. System composition
1. Field data acquisition and control: Field flowmeters, pressure transmitters, differential pressure transmitters, temperature transmitters and other equipment conduct real-time data acquisition and equipment control on the scene.
2. Wireless data communication: The wireless data communication part uses 3G/4G wireless transmission mode to transmit data to the destination center through the Internet. The use of wireless data transmission can save a lot of manpower and material resources, and achieve convenient deployment and easy maintenance.
3. Monitoring center: Data processing and analysis servers such as dispatch center servers, front-end servers, and WEB servers analyze and classify the received data in real time, and display the necessary parts in the WEB, so that the data obtained by the staff is accurate in real time.
