Problems solved by technology
The complex changes in the downstream water level caused by the outflow flow will affect the normal operation of the hydropower station and bring uncertainty to the downstream safety. Therefore, it is necessary to accurately predict the outflow flow and the rise in the downstream water level.
At present, various ground sensors and other monitoring equipment are mainly used to collect information such as the water level downstream of the dam, combined with manual placement, etc., not only the workload is large, the labor cost is high, and the sensor work is also easily affected by the collection environment and working years, which is not conducive to low cost. , Efficient and accurate prediction of downstream water level

Embodiment approach
[0029] On the basis of the discussion of the above step S102, the present invention also provides an implementation manner of obtaining a dam downstream water level prediction model corresponding to the target dam, including:
[0030] (1) Obtain the dam parameters of the target dam and the preset downstream water level formula. Among them, the above-mentioned dam parameters may include historical discharge flow, discharge time, initial water level of downstream section, water level increase, flow velocity, water depth, water area, section water level difference, channel geological characteristics, and valley shape (V, U shape, etc.) , bedrock characteristics, observation and analysis results, etc. Dam parameters play a vital role in building a dam downstream water level prediction model. For example, in practical applications, structural parameters such as channel geological characteristics, valley shape, and bedrock characteristics of the target dam can be collected, and the ...

Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle inspection, in particular to a method, device and terminal equipment for predicting the downstream water level of a hydropower station. Background technique [0002] In the process of hydropower station operation and dispatch, the discharge flow after flood storage dispatch operation will have an impact on the water level and flow amplitude of the river downstream of the dam. During the mission, the discharge flow of the hydropower station will change drastically, and it is easy to form unsteady water flow in the downstream river channel with sharp changes in water level and flow velocity (that is, the unsteady flow characteristics of the downstream of the hydropower station). The complex changes in the downstream water level caused by the outflow flow will affect the normal operation of the hydropower station and bring uncertainty to the downstream safety. Therefore, it is necessa...
