Based on the method, the cost required by water level prediction can be reduced, and the efficiency and accuracy of water level prediction are improved, so that unmanned full-automatic inspection and prediction are realized.
To facilitate understanding of the present embodiment, first, a method for predicting a downstream water level of a hydropower station disclosed in the embodiment of the present invention is described in detail, specifically referring to a schematic flow chart of the method for predicting a downstream water level of a hydropower station shown in fig. 1, where the method is applied to a server, and the server is in communication connection with an unmanned aerial vehicle, and the method mainly includes the following steps S102 to S106:

In an embodiment, the downstream water level prediction model of the dam can be constructed according to dam parameters of the target dam and a downstream water level formula, and the downstream water level formula can be an empirical formula established according to historical water level information, so that the required downstream water level prediction model of the dam can be obtained.
And step S104, controlling the unmanned aerial vehicle to acquire the current elevation information of the downstream water area of the target dam. The downstream water area (i.e., the submerged area) can be understood as an area submerged by the water level of the river of the dam rising and returning, and the current elevation information refers to the distance from the horizontal plane to the upper end of the target dam. In one embodiment, the drone may penetrate into the submerged area of the target dam to collect corresponding image data or point cloud data, so as to calculate current elevation information of the downstream water area based on the data.

In practical application, an uploading channel of the dam delivery flow can be provided for workers, related workers can set the dam delivery flow of the target dam according to the collected current elevation information in combination with practical work experience or other reference information, the dam delivery flow and the current elevation information are input into the dam downstream water level prediction model, the dam downstream water level prediction model is used for predicting the elevation difference value of a downstream water area, and then the water level information of the downstream water area is obtained based on the elevation difference value.
According to the method for predicting the downstream water level of the hydropower station, provided by the embodiment of the invention, the current elevation information of the downstream water area is acquired through the unmanned aerial vehicle, and the water level information is determined by utilizing the downstream water level prediction model of the dam based on the current elevation information and the flow of the dam leaving the reservoir, so that the full-automatic routing inspection and the water level prediction of the hydropower station dam are realized.
Based on the above discussion of step S102, the present invention further provides an implementation method for obtaining a dam downstream water level prediction model corresponding to a target dam, including:
(1) and acquiring dam parameters of the target dam and a preset downstream water level formula. The dam parameters may include historical ex-warehouse flow, ex-warehouse time, downstream section initial water level, water level fluctuation, flow velocity, water depth, water area, section water head, river channel geological characteristics, river valley morphology (V, U type, etc.), bedrock characteristics, observation and analysis results, and the like.

In an optional implementation manner, a constant in the downstream water level formula may be fitted according to the dam parameters, so as to obtain a dam downstream water level prediction model, where variables of the dam downstream water level prediction model are current elevation information and dam outbound flow, and in a subsequent application process, the constant of the dam downstream water level prediction model may be adjusted according to the current elevation information and an elevation difference corresponding to the current elevation information, so as to further improve prediction accuracy of the dam downstream water level prediction model.
In order to accurately and clearly acquire the current elevation information of the submerged area, the embodiment of the invention provides a laser point cloud pod carried by an unmanned aerial vehicle, and on the basis of the step S104, the invention further provides an implementation mode for controlling the unmanned aerial vehicle to acquire the current elevation information of the downstream water area of the target dam, which comprises the following steps:
a) the method comprises the following steps And issuing the point cloud acquisition task to the unmanned aerial vehicle so as to acquire the point cloud data of the downstream water area of the target dam through a laser point cloud pod of the unmanned aerial vehicle. The point cloud data comprises a point cloud of a junction of a downstream target area of a target dam and a downstream water area, wherein the target area can comprise a downstream slope or a target point, the target point can select points with an included angle of 90 degrees with a water surface, such as a bridge pier, a rock mass and the like, and the point cloud collection task is used for indicating the unmanned aerial vehicle to go to a submerged area and collecting corresponding point cloud data. Specifically, the laser point cloud pod carried by the unmanned aerial vehicle can be used for collecting point cloud data of a downstream water area, and in practical application, in order to ensure the accuracy of the elevation information of the target dam, the point cloud data needs to be collected in a plurality of areas of the target dam.
b) The method comprises the following steps And receiving point cloud data acquired by the unmanned aerial vehicle, and determining the current elevation information of the downstream water area based on the point cloud data. In an alternative embodiment, the modeling may be performed based on point cloud data, such as establishing a model of the junction between the downstream slope and the downstream water area, or establishing a model of the junction between the target point and the downstream water area, where the size of the model is proportional to the actual size of the target dam, so that the current elevation information of the downstream water area may be determined based on the model.
Based on this, on the basis of the above discussion of step S106, the present invention further provides an embodiment of inputting the current elevation information and the dam outbound flow of the target dam into a dam downstream water level prediction model to obtain the water level information of the downstream water area, including: and estimating an elevation difference value based on the dam delivery flow of the target dam and the current elevation information by using a water level prediction model, and calculating the water level information of the downstream water area based on the current elevation information and the elevation difference value. In an optional implementation manner, since each constant parameter in the dam downstream water level model is determined, two variable parameters, namely current elevation information and dam downstream ex-warehouse flow, are input into the dam downstream water level prediction model, so that a corresponding elevation difference value can be calculated, and a sum of the elevation difference value (which may be a positive value or a negative value) and the current elevation information is the water level information of the downstream water area. For example, the flow rate of warehouse-out downstream of the dam is 100 cubic meters, the current elevation information is 30 meters, the elevation difference calculated by using the dam downstream water level prediction model is 2 meters, and the water level information is the sum of the current elevation information and the elevation difference, namely 30+ 2-32 (meters).
Furthermore, in order to facilitate the staff to know the water level change of the downstream water area, the embodiment of the present invention further provides an implementation manner for determining the water level change information, and the water level change information of the downstream water area can be generated according to the water level information of the downstream water area in the target time period. In practical application, the water level information of the target dam is in a dynamic change process, and the water level change condition in a certain time period (target time interval) can be determined according to the real-time water level information of the submerged area, for example, the corresponding water level daily variation can be obtained by continuously recording the water level information in one day, wherein the water level daily variation is the water level change information in one day.
Further, in order to visually display the water level information and/or the water level change information of the downstream water area, the embodiment of the invention further provides an implementation manner as shown below: and controlling the unmanned aerial vehicle to acquire a dam image of the target dam, generating a three-dimensional real-scene model of the target dam based on the dam image, and displaying water level information and/or water level change information of a downstream water area based on the three-dimensional real-scene model of the dam. The dam image comprises a target dam and a downstream drainage basin image, and the dam three-dimensional live-action model is used for displaying live-action information of the target dam and a downstream water area. In practical application, the unmanned aerial vehicle can also collect image information of a dam and a watershed of a target dam, and a three-dimensional real-scene model of the dam is established by utilizing the collected image information so as to display the actual situation of the target dam to a user in real time through the three-dimensional real-scene model of the dam, wherein parameters related to the three-dimensional real-scene model of the dam comprise a warehouse-out flow factor, a river channel erosion and deposition factor, a tail water level factor, a downstream water level factor, a water flow speed factor, a river channel area factor, a former warehouse-out flow and the like. Furthermore, a downstream water area can be simulated based on the water level information, the water level change information and the parameters, so that the water level information and/or the water level change information obtained through the prediction of the water level prediction model is displayed to a user through the dam three-dimensional real-scene model, and the user can be helped to timely and accurately master the water level information of the downstream of the dam.
To facilitate understanding of the water level prediction method provided in the foregoing embodiment, an application example of a method for predicting a downstream water level of a hydropower station is provided in an embodiment of the present invention, and specifically, referring to a flow diagram of another method for predicting a downstream water level of a hydropower station shown in fig. 2, the method includes the following steps S202 to S212:

In practical application, the unmanned aerial vehicle is provided with the laser point cloud pod, and point cloud data of a downstream water area of the target dam can be acquired by controlling the laser point cloud pod to designate a vertex scanning task.
Step S204: the real-time water level elevation (i.e., the current elevation information) of the downstream water area is calculated. In one embodiment, a model of a boundary between a slope and a downstream water area may be established through point cloud data, or a model of a boundary between a target point and a downstream water area may be established, so as to calculate an implementation water level elevation based on the model.
Step S206: and receiving the flow of the dam out of the warehouse. In one embodiment, the dam delivery flow rate can be determined by the staff according to the actual working conditions, and the dam delivery flow rate uploaded by the staff is obtained.
Step S208: and inputting the real-time water level elevation and the dam outlet flow into a pre-established dam downstream water level prediction model. In practical application, the real-time water level elevation and the dam delivery flow can be input into a dam downstream water level prediction model, the dam downstream water level prediction model outputs a corresponding elevation difference value, and water level information is obtained through calculation based on the elevation difference value and the real-time water level elevation. It should be noted that a water level prediction model can be pre-constructed according to dam parameters, in addition, the unmanned aerial vehicle can acquire images of the dam and the watershed of the target dam in real time to generate a dam three-dimensional real-scene model, and the dam three-dimensional real-scene model can display the water level conditions of the target dam and the downstream water area in real time.
