Urban water supplyDMAPartition metering management system

Solution Overview

Partition metering, also known as regional management, is the process of aligning the existing water supply network according to certain principles, Divided into several relatively independent subregions,Implement separate measurement of water consumption for each region. ”Regional Planning and Zoning(DMA, DistrictMetering Area)It refers to the comprehensive consideration of natural geographical features such as urban topography and landforms, administrative divisions, water pressure distribution, water plant distribution and supply capacity, donkey water meter count, and water usage,According to certain principles, in the water distribution system, several relatively independent metering areas are established by installing flow meters or water meters, closing some valves.

Solution Advantages

Implement the "two in one" approach'Water supply management

Reduce pipeline leakage and production sales gap

aBetter implementation of scheduling

◎ Guide pipeline network planning and renovation

◎ Beneficial for establishing representative hydraulic models of pipeline networks

Zoning principle

Partition measurement expansion for unified management-The principle is to plan, implement step by step, focus on management, and emphasize practicality. In design,Utilize modern information technology to transform existing pipeline networks and scheduling systems, achieving scientific and digital management,reduce

Leakage and improvement of the economic benefits of the enterprise.

Based on the principles of safe operation, convenient management, and economical selection, mature systems and advanced technologies are adopted in the design to improve the technical level of this project, ensuring safe and reliable construction, low investment, and quick results.

The design is based on the geographic information system of the pipeline network and the establishment of a hydraulic calculation model as the basis for the design of the partitioned metering and monitoring system,To achieve scientific implementation of the Huzhou Water Group's pipeline management system

Standardized management.

Based on the present and considering the future,While establishing a flow meter monitoring system for the water supply network,Improve the hardware and software environment of the company's computer system to ensure the normal operation of the traffic monitoring system, while also contributing to the company's future information network

Networking lays a solid foundation.

Solution Architecture

Pull basic information through hardware sensor network,Implement the various functional points of data storage, analysis, mining, and pipeline partition metering leakage control step by step along with the planned progress,Monitor the pipeline network, partition monitoring, and large user monitoring

Functions such as control, data analysis, pipe burst prediction, equipment management, and business management assist enterprises in their work

Solution Value

One is the water consumption within the region Instantaneous flow rate, minimum flow rate Provide detailed and accurate measurements for easy use of water Quantitative forecasting and economic evaluation;Summarize and display water source information, combined with highlighted water system information, hydrological information, etc,Macroscopically understand the overall situation of raw water. Real time monitoring of water source well operation, achieving multi-source scheduling, with built-in water source well operation evaluation standards, objectively evaluating the operating efficiency of each water intake pump,Thus guiding the selection of water pumps and optimizing energy consumption.

Two overDMAAdd a pressure adjustment device to regulate the inlet pressure,Implement stress management. Scientific pressure management can not only reduce the load on the pipeline network, extend the service life of pipelines and their ancillary equipment, but also reduce the leakage and vanadium generation rate;

Thirdly, based on the minimum nighttime flow change curve, new pipeline leaks can be quickly detected, and the leakage points can be narrowed down to locate and search for areas,Assist in locating leakage points;

The fourth is to determine the degree of leakage in different areas, identify possible leakage areas, and scientifically guide the determination of key leakage monitoring and control areas,Reduce the cost of leak detection and leak control maintenance.

implementDMAPartition measurement must be selected in advance1-2Establish pilot projects in various regions and carefully study the feasibility of the plan,If the plan is feasible, it will be implemented in batches and stages. When establishing a graded measurement area, in addition to meeting technical requirements

Please also consider the initial investment in equipment procurement and installation, as well as the investment in maintenance in the later stage, and conduct an economic benefit analysis,Calculate the equilibrium point. adoptDMAPartition metering can address a major issue that exists throughout the entire water supply network

Decompose the problem into many small issues in the local pipeline network,Solving them one by one is beneficial for simplifying complex problems,And express the results of reducing consumption in a quantitative way;It can effectively and quickly reduce the production and sales gap,Increase supply

Water management level and economic benefits.
