The water supply network is an important part of the urban water supply system, but the leakage problem has always been a problem faced by water supply enterprises. In order to address this issue, effective monitoring measures are needed. This article will introduce a water pipe network leakage monitoring solution based on IoT technology to improve water supply efficiency and management.
Status quo
Overview of the monitoring programme.
The leakage monitoring system of the tap water pipe network based on the Internet of Things technology mainly includes three parts: the perception layer, the network layer and the application layer. The perception layer mainly monitors and collects data on the flow, pressure, water quality and other parameters of the pipe network in real time through various sensors and instruments. The network layer transmits the collected data to the application layer wirelessly or wired; The application layer processes, analyzes, and displays the received data to provide decision-making support for managers.
2. Monitoring the implementation of the program.
1.Perception layer.
At the perception level, it is necessary to select appropriate sensors and meters, such as flow meters, pressure sensors, water quality detectors, etc. These devices and sensors need to be installed at various critical nodes of the pipe network to monitor the operating status of the pipe network in real time. In addition, it is also necessary to establish a data acquisition system to collect pipe network data regularly or in real time, and ensure the accuracy and completeness of the data.
2.Network layer.
The main task of the network layer is to transmit the data collected by the sensing layer to the application layer. In this process, the reliability and real-time nature of data transmission need to be considered. Data transmission can be carried out in wireless or wired ways, such as NB-IoT, LoRa and other IoT communication technologies. At the same time, data transmission protocols and standards need to be established to ensure the uniformity and standardization of data.
3.Application layer.
The application layer is the core part of the entire monitoring system, which needs to be processed, analyzed, and displayed with the received data. First, the data needs to be preprocessed, anomalous and erroneous data removed, and the data normalized. Then, the data is analyzed through algorithms, such as flow analysis, pressure analysis, water quality analysis, etc., to find anomalies. Finally, the analysis results are displayed to managers through visualization technology, such as large-screen display, mobile APP, etc. In addition, the application layer also needs to establish an early warning and alarm system to detect and deal with abnormal situations in a timely manner.
3. Advantages of the monitoring program.
The water network leakage monitoring solution based on IoT technology has the following advantages:
1.Improve monitoring accuracy: Real-time monitoring with high-precision sensors and meters can improve the accuracy and reliability of data.
2.Reduce leakage rate: Through real-time monitoring and analysis of pipe network data, abnormal conditions can be detected and dealt with in a timely manner, thereby reducing the leakage rate.
3.Improve management efficiency: Through data visualization and early warning and alarm system, it can improve the work efficiency and response speed of management personnel.
4.Reduced maintenance costs: Unnecessary repair and replacement costs can be reduced by identifying and addressing problems in a timely manner.
5.Energy saving: Energy consumption and environmental impact can be reduced by optimizing water supply scheduling and reducing leakage.
