Description

Technical Field

[0001] This invention relates to the field of early warning system technology, and specifically to a reservoir water release early warning system based on image recognition. Background Technology

[0002] As is well known, during the rainy season, rainfall is relatively concentrated, and the water level in reservoirs rises significantly. To ensure the safety of the reservoir, water is usually released. At the same time, to ensure the safety of the downstream area during the release process, the release volume is usually monitored and the downstream area is notified. During the release monitoring process, sensors and other detection terminals are usually used for real-time monitoring, and the flow rate is calculated based on the sensor monitoring data. However, the detection data is not very intuitive and is prone to failure when the water flow is large. Therefore, to optimize the detection effect, a reservoir release early warning system based on image recognition is proposed.

[0003] A search revealed that Chinese patent CN108711267A, published on June 29, 2021, discloses a reservoir flood discharge early warning and monitoring system. Its general description includes a central station, a monitoring box, and multiple communication equipment boxes. Each of the communication equipment boxes and the monitoring box contains a remote control unit (RTU), switching equipment, a surge protector, two batteries, a wireless receiving module, and a wireless transmission module. All communication equipment boxes and the monitoring box are connected to the central station via the wireless receiving module. The monitoring box contains a programmable PLC. A submersible level gauge probe is connected to the monitoring box via a dedicated cable. The submersible level gauge probe is protected by a protective tube. Solar panels are fixedly connected to the upper surfaces of all communication equipment boxes and the monitoring box. A rain gauge is fixedly connected to the upper surface, located to the left of the solar panel. Above each of the multiple communication equipment boxes are flood control loudspeakers, high-definition video surveillance, and flashing alarms. During operation, the monitoring box connects to an immersion-type level gauge probe and the rain gauge for real-time monitoring. All communication equipment boxes and monitoring boxes are connected to the central station via wireless receiving modules, facilitating real-time feedback of monitored information. The high-definition video surveillance system can monitor the upstream reservoir and downstream river conditions in real time. Simultaneously, it can collect on-site images and relevant data as needed, uploading them to the integrated command platform to support emergency command and prevent personnel and property losses caused by flood discharge or water release.

[0004] While the aforementioned existing technical solutions can be used in reservoir flood discharge to achieve early warning, their detection relies on level gauge probes and rain gauges. The detection data needs to be converted to obtain specific data that can be viewed by emergency command, resulting in poor data intuitiveness. In addition, the detection is mainly carried out through electronic products such as level gauge probes and rain gauges. When the water flow is too large, the electronic products are easily damaged, and the reliability of use needs to be further improved. Summary of the Invention
