With the development of social economy and the impact of climate change, the safety of reservoirs has attracted more and more attention. In order to ensure the safe operation of reservoirs, it is very important to improve the ability of reservoirs to monitor rainwater conditions and dam safety. According to the scale of the reservoir, a number of monitoring points are set up to realize the automatic collection of rainfall, water level, flow rate, flow rate and image (video) in the reservoir area. According to the distance and topography of the equipment installation position and the monitoring center, a variety of communication modes can be selected, and after the completion of the system, the real-time monitoring of the rainfall and water level in the reservoir basin will be further realized, and the water situation, rain information will be obtained in a timely and accurate manner, and the flood prediction level will be improved, and the ability of disaster prevention and disaster resistance and water distribution dispatching will be enhanced.
First, the system composition
In order to meet the needs of water level and precipitation emergency monitoring, the water level and rainfall system is equipped with a water level and rainfall emergency monitoring machine, which mainly includes two parts of rainfall and water level observation, namely pressure water level gauge, tipping bucket rain gauge, data collection terminal, battery, GSM module, camera and portable bracket. The data acquisition terminal is integrated with the water level gauge, rain gauge and communication equipment to form an automatic water level and rain gauge station of the integrated device, and realize the comprehensive functions of automatic collection, processing, storage and transmission of rainfall information. On-site installation is simple and can be completed in less than 10 minutes. The radar water level gauge and the tipping bucket rain gauge share the transmission and power supply parts.
2. Data collection
The sensor data collected by the telemetry terminal is sent to the server, which is mainly used to display information such as soil moisture, soil PH, wind speed, wind direction, rainfall, atmospheric temperature and humidity, water level, flow and other information of each station. Users can wake up the remote terminal at any time in the provincial center or sub-center to perform RTU program upgrades, parameter settings, data calling, data downloading and other operations; It has a communication signal diagnosis function, which can help maintenance personnel analyze the operation status of the station; Built-in 4G communication module of full Netcom to meet the communication stability in the case of complex terrain and inconvenient transportation; Missing data can be automatically reissued to ensure the integrity of the data of the provincial center or sub-center.
Third, the data shows
After the server gets the data, it will be displayed in real time, which can view the real-time data of all sites, historical data, reports, curves, historical graphics, site picture capture, site video, data export, EXCLE report, GIS geographic information data, multi-site multi-data comparison, multi-station data comparison, early warning and forecasting of a single site. Users can query in real time through the computer or mobile phone.
Reservoir rainwater monitoring and dam safety monitoring solutions provide a strong guarantee for reservoir dams. It can be monitored in real-time around the clock, grasp the water flow situation, and respond to distress in real time. The integration of big data and meteorological data to accurately predict the flood season situation and deploy it in advance is of great significance for reservoir dam monitoring and flood prevention and disaster reduction.
