[0033] The principles and features of the present invention will be described below. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0034] The technical solution of the present invention and how the technical solution of the present invention solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0035] As Figure 1 shown, a method for simultaneously measuring the flow rate and flow velocity at different depths of surface water according to an embodiment of the present invention includes the following steps:

[0036] S1. Fit the flow measurement data of the flow measurement section at the target flow measurement position of the reference surface water to obtain a first fitting function for characterizing the variation relationship between the flow velocity and the depth, and obtain a second fitting function for characterizing the variation relationship between the flow rate and the flow velocity of the sub-section in the flow measurement section of the reference surface water;

[0037] Among them, the reference surface water refers to: the surface water used to obtain the flow measurement data.

[0038] Among them, considering the following factors, the target flow measurement position of the reference surface water is determined. Specifically:

[0039] 1) Avoid dead water areas and backwater areas.

[0040] 2) Select a position with a stable riverbed, smooth water flow, a wide water surface, and a position on a straight river section of the surface water.

[0041] Among them, the flow measurement data of the flow measurement section at the target flow measurement position of the reference surface water includes: on the flow measurement section at the target flow measurement position of the reference surface water, the depth-flow velocity data (depth-flow velocity data is: the variation data of the flow velocity with the depth) along each flow measurement vertical line.

[0042] After obtaining each depth-flow velocity data at the target flow measurement position of the reference surface water, through flow measurement-related knowledge, the flow rate of each sub-section on the flow measurement section at the target flow measurement position can be calculated, and a second fitting function for characterizing the variation relationship between the flow rate and the flow velocity of the sub-section in the flow measurement section of the reference surface water is fitted. The second fitting function is: the product of the average flow velocity, the bank coefficient, and the area of any sub-section within the sub-section is the flow rate of the sub-section.

[0043] Among them, the explanation of a sub-section is as follows: The area between two adjacent flow measurement vertical lines in a flow measurement section is a sub-section, and the areas between the two end flow measurement vertical lines and the sides of the flow measurement section closest to them are also sub-sections.

[0044] Among them, the process of obtaining each depth-velocity data at the target flow measurement position of the reference surface water is as follows:

[0045] At the target flow measurement position of the reference surface water, a measuring rod is vertically arranged along the flow measurement vertical line. The other side of the measuring rod is fixed at the bottom of the water body of the reference surface water. A plurality of velocity sensors are arranged on the measuring rod, and the sampling frequency of each velocity sensor is set to obtain the velocities at different water depths at different times, that is, the velocity time series data at different water depths. The mean value of the velocities in the velocity time series data at each water depth is used as the corresponding velocity. Thus, the data of the change of the velocity with depth of the flow measurement vertical line where the measuring rod is located is obtained. By changing the position of the measuring rod, the data of the change of the velocity with depth of each flow measurement vertical line is obtained.

[0046] Among them, the process of obtaining the first fitting function is as follows:

[0047] Perform data fitting on the vertical distance (depth) between each velocity sampling point (i.e., the position where the velocity sensor is located) and the water surface of the reference surface water, the vertical distance between each velocity sampling point and the bottom of the water body of the reference surface water, the vertical distance between each velocity sampling point and the shore, and the data of the change of the velocity with depth of each flow measurement vertical line, to obtain a first fitting function with the "vertical distance between the velocity sampling point and the water surface, the vertical distance between the velocity sampling point and the bottom of the water body of the reference surface water, the vertical distance between the velocity sampling point and the shore" as the independent variable and the velocity as the dependent variable.

[0048] Among them, specifically, the first fitting function can be obtained by using non-linear regression for fitting. Or, using the vertical distance (depth) between each velocity sampling point (i.e., the position where the velocity sensor is located) and the water surface of the reference surface water, the vertical distance between each velocity sampling point and the bottom of the water body of the reference surface water, the vertical distance between each velocity sampling point and the shore, and the data of the change of the velocity with depth of each flow measurement vertical line, train machine learning algorithms such as a trained decision tree, random forest, support vector machine or neural network, to obtain a trained machine learning algorithm. The trained machine learning algorithm is the first fitting function. The input of the machine learning algorithm is: the vertical distance between the velocity sampling point and the water surface, the vertical distance between the velocity sampling point and the bottom of the water body of the reference surface water, the vertical distance between the velocity sampling point and the shore, and the depth. The output of the machine learning algorithm is: the predicted value of the velocity.

[0049] S2. Obtain the flow velocity at a preset position on the cross-section of the preset flow measurement position of the surface water to be measured, and according to the first fitting function, obtain the flow velocity at each position on the cross-section of the preset flow measurement position of the surface water to be measured, and use the second fitting function to calculate the flow rate of each sub-cross-section on the cross-section of the preset flow measurement position of the surface water to be measured.

[0050] Among them, the preset flow measurement position can be set according to the actual situation.

[0051] Among them, when obtaining the first fitting function, the vertical distance (depth) between the flow velocity sampling point (i.e., the position where the flow velocity sensor is located) and the water surface of the reference surface water is used. However, when applying the first fitting function, the depth of the preset position needs to be used as the standard depth, calculate the vertical distance between any position other than the preset position on the cross-section of the preset flow measurement position of the surface water to be measured and this standard depth, and bring this vertical distance, as well as the vertical distance between this any position and the bottom surface of the reference surface water, and the vertical distance between this any position and the shore into the first fitting function to calculate the flow velocity of this any position until the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured is calculated.

[0052] It should be noted that the meaning of "simultaneous measurement" in the subject name of the present invention is: through the technical solution of the present invention, the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured and the flow rate of each sub-cross-section on the cross-section of the preset flow measurement position of the surface water to be measured can be obtained in real time, rather than the "simultaneous measurement" in the truly strict sense. Therefore, during the process of calculating the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured and obtaining the flow rate of each sub-cross-section on the cross-section of the preset flow measurement position of the surface water to be measured, there will be a certain calculation duration.

[0053] Optionally, in the above technical solution, it further includes:

[0054] S3. Optimize the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured, and optimize the flow rate of each sub-cross-section on the cross-section of the preset flow measurement position of the surface water to be measured.

[0055] Optionally, in the above technical solution, optimizing the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured includes:

[0056] Optimize the flow velocity of each position on the cross-section of the preset flow measurement position of the surface water to be measured according to the similarity between the cross-section of the target flow measurement position of the reference surface water and the cross-section of the preset flow measurement position of the surface water to be measured.

[0057] Due to the different shapes of the flow measurement cross-sections, the accuracy of the flow velocity at each position on the flow measurement cross-section at the preset flow measurement position of the surface water to be measured will be affected. Therefore, optimizing the flow velocity at each position on the flow measurement cross-section at the preset flow measurement position of the surface water to be measured based on the similarity between the flow measurement cross-section at the target flow measurement position of the reference surface water and the flow measurement cross-section at the preset flow measurement position of the surface water to be measured can improve the accuracy of the data.

[0058] Among them, the process of calculating the similarity between the flow measurement cross-section at the target flow measurement position of the reference surface water and the flow measurement cross-section at the preset flow measurement position of the surface water to be measured is as follows:

[0059] S301. Obtain the image of the flow measurement cross-section at the target flow measurement position of the reference surface water, denoted as the first image, and obtain the image of the flow measurement cross-section at the preset flow measurement position of the surface water to be measured, denoted as the second image. The sizes of the first image and the second image are the same.

[0060] S302. Obtain the grayscale image corresponding to the first image, denoted as the first grayscale image, and obtain the grayscale image corresponding to the second image, denoted as the second grayscale image. Among them, the sizes of the first grayscale image and the second grayscale image are the same.

[0061] S303. Convert the first grayscale image into a binary image, denoted as the first binary image, and convert the second grayscale image into a binary image, denoted as the second binary image. Among them, the images of the first binary image and the second binary image are the same.

[0062] S304. Arrange the pixel values in the first binary image and the pixels in the second binary image in the same order to obtain two arrays. Calculate and use the Euclidean distance, cosine similarity, or Pearson correlation coefficient between these two arrays as the similarity between the flow measurement cross-section at the target flow measurement position of the reference surface water and the flow measurement cross-section at the preset flow measurement position of the surface water to be measured. The calculation process is simple and can also ensure the accuracy of the calculated similarity.

[0063] In another implementation, when the first image and the second image are obtained, the similarity between the first image and the second image can be directly calculated as the similarity between the flow measurement cross-section at the target flow measurement position of the reference surface water and the flow measurement cross-section at the preset flow measurement position of the surface water to be measured.

[0064] Optionally, in the above technical solution, the flow velocity at the preset position on the flow measurement cross-section at the preset flow measurement position of the surface water to be measured is: the flow velocity at the water surface at the preset flow measurement position of the surface water to be measured, and the flow velocity at the water surface at the preset flow measurement position of the surface water to be measured is measured by a radar flow velocity meter.

[0065] In the above embodiments, although the steps are numbered as S1, S2, etc., these are only specific embodiments given by the present invention. Those skilled in the art can adjust the execution order of S1, S2, etc. according to the actual situation, which is also within the protection scope of the present invention. It can be understood that in some embodiments, it may include some or all of the above embodiments.

[0066] As Figure 2 shown, a simultaneous measurement system 200 for the flow rate and flow velocity at different depths of surface water according to an embodiment of the present invention includes a data fitting module 201 and a measurement and calculation module 202;

[0067] The data fitting module 201 is configured to: fit the flow measurement data of the flow measurement section at the target flow measurement position of the reference surface water to obtain a first fitting function for characterizing the variation relationship between the flow velocity and the depth, and obtain a second fitting function for characterizing the variation relationship between the flow rate and the flow velocity of the sub-section in the flow measurement section of the reference surface water;

[0068] The measurement and calculation module 202 is configured to: obtain the flow velocity at a preset position on the flow measurement section at the preset flow measurement position of the surface water to be measured, and according to the first fitting function, obtain the flow velocity at each position on the flow measurement section at the preset flow measurement position of the surface water to be measured, and use the second fitting function to calculate the flow rate of each sub-section on the flow measurement section at the preset flow measurement position of the surface water to be measured.

[0069] Optionally, in the above technical solution, it further includes a data optimization module, and the data optimization module is configured to:

[0073] Optionally, in the above technical solution, the flow velocity at the preset position on the flow measurement section at the preset flow measurement position of the surface water to be measured is: the flow velocity at the water surface at the preset flow measurement position of the surface water to be measured, and the flow velocity at the water surface at the preset flow measurement position of the surface water to be measured is measured by a radar flow velocity meter.
