1. System overview
The real-time perception and monitoring system of the drainage pipe network aims to monitor the operation status of the drainage pipe network in many aspects in real time, and timely find abnormal conditions in the pipe network, such as blockage, leakage, abnormal water level, etc., so as to improve the operation efficiency and safety of the drainage system and ensure the normal drainage and water environment quality of the city. The system will comprehensively use sensor technology, Internet of Things technology, data analysis technology, etc., to realize the intelligent monitoring and management of the drainage pipe network.
Second, the system composition
1. Sensor networks
- Water level sensor: Installed at key nodes of the drainage network, inspection wells, etc., to monitor water level changes in real time. When the water level exceeds the set threshold, an alarm signal is immediately issued.
- Flow sensors: used to measure the flow of water in a drainage network to help analyze the drainage capacity and flow changes of the network.
-Water quality sensor: monitor water quality parameters in the drainage network, such as pH, chemical oxygen demand (COD), suspended solids (SS), etc., so as to detect excessive sewage discharge or abnormal changes in water quality in the pipe network in time.
- Pressure sensors: Installed at pressure control points such as pumping stations, to monitor pipeline pressure and prevent damage to the pipe network caused by excessive or low pressure.
2. Data Transmission Networks
- Using the Internet of Things technology, the data collected by the sensor is transmitted to the monitoring center in real time through wireless communication methods such as 4G communication or wired form. Ensure the stability, timeliness and accuracy of data transmission.
3. Monitoring Center
- Hardware facilities: including servers, large monitoring screens, operation terminals and other equipment for receiving, storing, processing and displaying monitoring data.
- Software system: It has the functions of data receiving and processing, data analysis and early warning, report generation, pipe network simulation, etc. It can analyze the sensor data in real time, judge whether the pipe network is operating normally according to the preset rules, and issue alarms in abnormal cases. At the same time, the operation of the pipe network under different working conditions can be predicted through the pipe network simulation function, which provides decision support for optimizing the operation of the drainage system.
3. System functions
1. Real-time monitoring
- Real-time display of water level, flow, water quality, pressure and other data of each monitoring point in the drainage network, providing an intuitive monitoring interface.
2. Data analysis and early warning
- Analyze monitoring data to identify abnormal data patterns. For example, when water levels rise sharply or flow increases suddenly, it may indicate a blockage in the pipe network or an influx of rainstorm runoff; When the water quality parameters exceed the standard, the water pollution warning will be issued in time.
- Based on historical and real-time data, build a prediction model to provide early warning of possible network problems, such as predicting possible waterlogging areas during heavy rainfall.
3. Reports and statistics
- Generate daily, monthly, and annual reports of various monitoring data to facilitate long-term tracking and analysis of the operation of the pipe network.
- Statistical analysis of the frequency of pipe network failures and water quality change trends, etc., to provide data support for pipe network maintenance and management.
4. Remote control
- Integrate with the control system of equipment such as dewatering pumping stations to remotely control the start and stop of pumping stations, adjust flow and other operations to optimize the operation of drainage systems.
Fourth, the implementation steps
1. Demand research and planning
- Conduct a detailed investigation of the layout, scale, and operation characteristics of the urban drainage network, and determine the location and number of monitoring points.
- Develop the overall architecture and functional requirements planning of the system.
2. Equipment selection and installation
- Select the appropriate hardware facilities such as sensors and communication equipment according to your needs.
- Install and debug the sensor to ensure accurate measurement and stable operation.
3. Data transmission network construction
- Build a wireless communication network to ensure that sensor data can be transmitted to the monitoring center safely and stably.
4. Construction of monitoring center
- Install and configure the hardware and software systems of the monitoring center.
- Debugging and optimizing the software system to ensure that its functions are functioning properly.
5. System testing and optimization
- Perform multi-faceted testing of the entire monitoring system, including sensor data accuracy, data transmission stability, monitoring center function, etc.
- Optimize and improve the system based on the test results to ensure that the system meets the expected performance indicators.
6. Training and operation and maintenance
- Train system managers and operators to familiarize them with the operation and maintenance methods of the system.
- Establish a system operation and maintenance system, and regularly maintain and overhaul sensors, communication equipment, monitoring centers, etc., to ensure the long-term stable operation of the system.
V. Conclusion
The real-time perception and monitoring system of the drainage pipe network is an important part of smart water, which is of great significance for improving the operation and management level of the urban drainage system and ensuring the safety of urban water. Similarly, the real-time perception and monitoring system of the water supply network can also be built with reference to the above scheme, but it will be different in terms of sensor type and monitoring focus, for example, the water supply network may pay more attention to the monitoring of pressure, flow, leakage, etc.
