Program overview
Reservoir project is a small reservoir project that focuses on landscape water supply and takes into account flood control. It establishes a quick-response automatic hydrological forecasting system to collect hydrological and water quality data in a timely and accurate manner, and conduct water quality monitoring and hydrological forecasts to increase the effective forecast period It is very necessary to take measures in advance.
In the management process of reservoir dams, affected by changes in rainfall, water pressure, water quality pollution and temperature, including the aging and damage of the dam itself of the pivotal project, safety problems may arise and there are hidden safety hazards. In order to verify the design and construction quality, ensure the safety of dam operation, and discover problems in time, comprehensive safety monitoring of the dam is required.
Goals
Reservoir water quality monitoring system collects sub-systems such as real-time water quality monitoring, water and rain regime monitoring system, and reservoir building safety monitoring.
The real-time monitoring of water quality and the water and rain monitoring system can realize automatic collection of rainfall, water level, water quality, and images (video) in the reservoir area. After the system is completed, real-time monitoring of the reservoir will be further realized, and real-time water quality, water regime, and rain regime information will be obtained timely and accurately, which not only effectively guarantees the safety of water quality, but also improves the level of flood prediction and reporting, and enhances disaster prevention and water distribution and dispatching capabilities.
The dam safety monitoring system is based on the current technical level, deploying seepage pressure gauges on the dam body of the reservoir, automatically monitoring and reporting the dam seepage pressure in real time, improving the level of dam safety monitoring, and reducing hidden dangers of dam safety.
Scheme principle
The composition of the reservoir water quality monitoring system is mainly divided into a four-tier architecture model. The sensing data is collected by the front-end sensing layer, and the data is collected and transmitted to the platform layer for analysis and processing by the water conservancy telemetry terminal equipment of the transmission layer. Finally, users at the application layer make comparison decisions on data information.
Sensing layer: It is mainly composed of front-end data sensing (collection) and related output equipment, including water quality meters, ultrasonic water level meters, radar flow meters, flow meters, rain gauges, piezometers, dam pressure, displacement, deformation and other sensors and High-definition cameras and other equipment conduct real-time data collection and equipment control on the scene.
Network layer: It is mainly composed of equipment responsible for collecting, communicating, transmitting and controlling the data output by the perception layer. According to different business needs and environments, you can choose to use the iot. The data transmission equipment of Jixun IOT integrates 5G/4G wireless transmission and data collection. Rich interfaces can connect more sensors and monitoring equipment.
Platform layer: mainly composed of data server, application server and large monitor screen. It mainly realizes the functions of data storage, calculation, analysis and monitoring, timely processing the data returned from the front end, and real-time monitoring of reservoir water quality and rainwater regime information. Through the monitoring center, terminal PC and data server to analyze and organize the data in real time, remote mobile terminals can also access the equipment and confirm data information through the Internet of Things.
Application layer: It is mainly composed of remote monitoring platforms of various competent departments, such as: reservoir management center, water conservancy department, environmental protection department, etc. The monitoring center uses the monitoring center, terminal PC and data server to analyze and organize the data in real time to achieve remote monitoring, Real-time scheduling and scientific decision-making.
