[0002] Water conservancy and hydropower projects involve a wide range of construction processes, including dams, levees, sluice gates, and penstocks. Traditional technologies rely on physical model testing and empirical formulas, while modern technologies integrate numerical simulation (finite element analysis, CFD), BIM (Building Information Modeling), and IoT monitoring to achieve full project lifecycle management. A typical project, such as the Three Gorges Project, involved complex technologies such as large-scale concrete pouring and high dam seismic design. Inspection and acceptance are conducted after completion of the construction project.

However, the conclusions drawn from this one-time verification may have large errors. With the massive amount of data compared, the errors eventually accumulated, resulting in poor accuracy in the inspection of the building. Summary of the Invention

[0049] Please refer to Figure 1-Figure 2 , a detection method for water conservancy and hydropower projects, comprising:

[0050] S101: Setting inspection base points for hydraulic structures, obtaining inspection data of the inspection base points, determining whether the current hydraulic structures are qualified based on the inspection data and a judgment threshold of the inspection data, obtaining a number of qualified first hydraulic structures and a number of unqualified second hydraulic structures, obtaining a first unqualified rate of the current water conservancy and hydropower project based on the number of the first hydraulic structures and the second hydraulic structures, and issuing an alarm signal indicating unqualified inspection if the first unqualified rate is not zero;

[0051] Among them, the detection base point is the point where sampling is carried out on the hydraulic structure or related data measurement is carried out. A series of detection methods such as testing and experiments are carried out on the collected samples, and finally an evaluation is carried out. The hydraulic structures include dams, spillways, tunnels, embankments, sluices, pressure pipes, etc. In this embodiment, the main detection objects are dams, spillways and tunnels. Specific selection can be made according to different situations during actual use. In this embodiment, as long as there are unqualified hydraulic structures, the current detection result can be determined as unqualified.

[0052] S102: If the first unqualified rate is zero, basic data of several hydraulic structures are obtained, a calculation coefficient of the hydraulic structure is set based on the basic data of the hydraulic structure, a judgment threshold of the first hydraulic structure is modified based on the calculation coefficient, and then whether the first hydraulic structure is qualified is determined to obtain an updated second unqualified rate;

[0053] In this embodiment, the first hydraulic structure that has passed the first preliminary inspection is re-inspected, wherein a calculation coefficient that can change the judgment threshold is set according to the basic data of each hydraulic structure, and a second judgment is performed after the judgment threshold is changed.

[0054] S103: If the second unqualified rate is not zero, an alarm signal of unqualified detection is issued; if the second unqualified rate is zero, the detection base point of the first hydraulic structure is updated, the detection data of the updated detection base point is obtained, and it is determined whether the current first hydraulic structure is qualified to obtain the updated third unqualified rate; if the third unqualified rate is not zero, an alarm signal of unqualified detection is issued; if the third unqualified rate is zero, a signal that the current hydraulic structure has passed the inspection is issued.

[0055] In this embodiment, a third test is performed, the position of the test base point is changed, and new test data is obtained. A third judgment test is performed based on the collected data obtained for the second time, and finally a more accurate test result is obtained.

[0056] The method provided by the present invention mainly includes judging whether the current hydraulic structure is qualified based on the test data and the judgment threshold of the test data. It is configured so that if the first unqualified rate is zero, the judgment threshold of the first hydraulic structure is corrected based on the calculation coefficient. If the second unqualified rate is zero, the detection base point of the first hydraulic structure is updated, the detection data of the updated detection base point is obtained, and whether the current first hydraulic structure is qualified is judged. Through the above method, multiple detection verifications are carried out by respectively correcting the judgment threshold and replacing the detection base point, thereby reducing the error during detection as much as possible and improving the credibility and accuracy of the final detection result.

[0057] In an exemplary embodiment of the present invention, the setting of detection base points of hydraulic structures includes:

[0058] S201: Obtain a three-dimensional model of the current hydraulic structure. If the current hydraulic structure is a solid structure, obtain the center of mass of the hydraulic structure through the three-dimensional model, and divide the current three-dimensional model into three equal parts along the length direction of the three-dimensional model;

[0059] In this embodiment, hydraulic structures are divided into solid and hollow ones. Solid structures such as dams and hollow structures such as tunnels are distinguished and analyzed. Several areas are distinguished within the solid structure. The approximate location of the center of mass can be roughly judged as being in the middle, to the left, or to the right. Different treatments are performed according to the different areas where the center of mass is located. Secondly, if the area is a very irregular structure or shape, it can be equivalent to a relatively regular cuboid.

[0060] S202: Mark the area where the centroid is located as the centroid area, and determine whether the centroid area is located between the other two areas. If so, connect the centroid with each vertex of the three areas to obtain several target lines. If not, connect the centroid with all vertices of the centroid area, and connect the centroid with one vertex of the other two areas respectively to obtain several target lines.

[0061] S203: Obtain the midpoint of the target line, and establish a target plane parallel to the bottom surface of the hydraulic structure along the midpoint;

[0062] S204: The area where the target plane contacts the surface of the hydraulic structure is a detection base point selection area, and any point in the detection base point selection area is selected as a detection base point;

[0063] If the centroid area is located between the other two areas, it means that the position of the centroid point is biased to the middle. Then the vertices of the entire three-dimensional model can be taken into consideration, and several target lines are obtained by connecting the lines. A target plane parallel to the ground of the three-dimensional model is established through the midpoint of the target line. The target plane is an infinitely large plane, which will intersect with the outer surface of the three-dimensional model to obtain several intersecting lines. These lines are the detection base point selection area. According to the number of detection base points to be selected, the detection base points are selected in the detection base point selection area.

[0064] S205: Obtain the quality of each area, and obtain the number of detection base points according to the quality of each area to set the ratio.

[0065] In an exemplary embodiment of the present invention, if the current hydraulic structure is a hollow structure, the maximum length value, maximum height value and maximum width value of the three-dimensional model are obtained respectively, and a rectangular model is constructed based on the maximum length value, maximum height value and maximum width value; the physical structure center of the rectangular model is obtained, and three different planes passing through the physical structure center and parallel to the surface of the rectangular model are established; the area where the three planes contact the surface of the hydraulic structure is defined as the detection base point selection area.

[0066] In this embodiment, due to the hollow structure, the center of mass point may not be on the three-dimensional model, which makes it inconvenient to establish the target plane. Therefore, the entire hydraulic structure is equivalent to a rectangular structure, and the physical center of the rectangular structure is found. Based on the physical center, the target plane is found, and then the detection base point selection area that intersects with the three-dimensional model is obtained.

[0067] In an exemplary embodiment of the present invention, judging whether a current hydraulic structure is qualified based on the detection data and the judgment threshold of the detection data includes:

[0068] Determine whether a number of test data are within the judgment threshold. If so, the current test data passes the test and outputs a signal that the current hydraulic structure is qualified.

[0069] If not, the number of test data that is not within the judgment threshold is obtained. If it is not within the set number threshold, a signal that the current hydraulic structure is unqualified is output. If it is within the set number threshold, a detection error is set to determine whether the difference between several test data and the maximum or minimum value of the judgment threshold is within the detection error. If so, the current test data passes the test and a signal that the current hydraulic structure is qualified is output. If not, the current test data fails the test and a signal that the current hydraulic structure is unqualified is output.

[0070] In an exemplary embodiment of the present invention, the calculation coefficient of the hydraulic structure is set based on the basic data of the hydraulic structure, including:

[0071] A calculation coefficient calculation model is established, wherein the model includes:

[0074] In this embodiment, the weight of various parameters of hydraulic structures in the entire water conservancy and hydropower project is taken into account to obtain a more comprehensive calculation data. The original judgment threshold is corrected by using the calculation coefficient. and The larger of the two values is the upper limit of the new judgment threshold, and similarly, the other one is the lower limit.

[0075] In an exemplary embodiment of the present invention, updating the detection base point of the first hydraulic structure includes:

[0076] Establishing a three-dimensional coordinate system, mapping the three-dimensional model to the three-dimensional coordinate system, and obtaining coordinate information of the centroid or the center of the physical structure based on the three-dimensional coordinate system;

[0077] A coordinate update model is established, and the current coordinate information is updated through the coordinate update model to obtain updated coordinate information. A new centroid point or physical structure center is obtained based on the updated coordinate information, and a detection base point of the first hydraulic structure is obtained based on the new centroid point or physical structure center.

[0078] Specifically, establishing the coordinate update model includes:

[0082] In this embodiment, the centroid point or the center of the physical structure is replaced, the coordinate data is calculated through the above calculation, and combined with the actual situation of the hydraulic structure, a new coordinate is obtained. The detection base point is re-searched through the new centroid point or the center of the physical structure to obtain different detection data and complete the third detection.

[0083] Specifically, it also includes:
