1. Policy requirements
The Ministry of Housing and Urban-Rural Development and the National Development and Reform Commission issued a notice on doing a good job in urban drainage and flood prevention in 2023. The notice mentioned that according to the predictions of relevant departments, the overall climate situation in the country in 2023 will be normal to deviation, with both droughts and floods, more extreme weather and climate events, and the situation of urban drainage and waterlogging prevention will be severe and complicated. Relevant competent departments in various places are required to pay close attention to various flood prevention and disaster relief measures, and comprehensively improve the city's ability to prevent and control waterlogging. Accelerate the construction of drainage and waterlogging prevention facilities, build a drainage and waterlogging prevention engineering system, pay close attention to the construction and renovation of drainage pipe networks, build intelligent monitoring and sensing equipment at important nodes, and improve the intelligent management level of drainage and waterlogging prevention facilities.
2. The importance of urban drainage network monitoring
1. Timely detection of pipeline problems: Due to long-term use and environmental factors, the urban drainage network is prone to problems such as water leakage, damage, and blockage. The low-power pipeline network intelligent monitoring equipment can monitor the operation status of the pipeline in real time and find problems in time.
2. Prevention of drainage accidents: During the operation of the urban drainage network, problems such as insufficient flow rate and low discharge pressure may occur. If these problems are not discovered and resolved in time, drainage accidents may occur. Low-power pipe network intelligent monitoring equipment can prevent or reduce drainage accidents by mastering parameters such as water flow, water level, and water pressure in the pipeline.
3. Improve the operation efficiency of the pipeline network: The pipeline network monitoring can analyze the parameters of the pipeline, such as water flow, water level, water pressure, etc., so that measures can be formulated to improve the operation mode and improve the operation efficiency of the pipeline network.
4. Ensure the quality of water environment: The disposal of urban drainage is one of the main factors affecting the quality of water environment. Through the monitoring of the drainage pipe network, problems such as overflow and retention of pollutants in the drainage system can be discovered or prevented in time to ensure the quality of the water environment.
3. How to monitor the urban drainage network
1. Adopt advanced monitoring equipment: Micro-power battery remote measurement and control terminal RTU is equipped with liquid level gauge, flow meter, water quality sensor and other equipment to conduct real-time online monitoring of flow, liquid level, water quality PH, pressure, etc. in the urban pipe network, and analyze These data and abnormal data exceed the standard automatic warning, find out pipeline problems and hidden dangers, and prompt which pipeline the problem lies in.
2. Build a data management platform: urban pipe network drainage monitoring system, use Internet of Things technology and wireless sensor technology to monitor urban pipe network sewage water quality, liquid level, flow and other parameters in real time, and GIS vector diagram to display the location distribution of each point. The data management center provides services such as data management, data query, and data analysis, and the official account provides functions such as data viewing, data management, and push alarm information.
Realize groundwater monitoring, water supply network monitoring, cellar well water level monitoring, sewage supervision, precise positioning, and help the construction and development of urban pipe networks.
4. Application value of urban drainage network monitoring
1. Real-time supervision, information management, precise positioning, providing traceability of water pollution, convenient for supervision and management of pollution control in a timely manner.
2. Reduce the cost of manpower management, comprehensive and real-time monitoring of urban sewage and pipe network flow, and eliminate the inaccuracy of on-site inspection by inspectors.
3. Provide favorable data basis for the flow, liquid level, and water quality management of the urban pipe network, facilitate the analysis of leakage, flood, water quality, etc. of the urban pipe network, and provide useful research data for the scientific research institute.
