[0062] The following description is used to disclose the application so that those skilled in the art can implement the application. The preferred embodiments in the following description are only as examples, and those skilled in the art can think of other obvious modifications.

[0063] Referring to Figure 1 A water conservancy dam quality detection method is shown, which comprises:

[0064] S100, based on an ultrasonic probe, detecting defects in the dam body to determine the dam defect position;

[0065] S200, the ultrasonic probe emits pulse signals to the dam body multiple times according to the dam body defect position, and obtains related data of the dam body defect, wherein the related data of the dam body defect includes a shape of the dam body defect and a depth of the dam body defect;

[0066] S300, based on the remote control end, analyzing and processing the related data of the dam body defect to determine the quality of the dam body;

[0067] As can be understood by those skilled in the art, when the pulse signal emitted by the ultrasonic probe encounters a defect, the pulse signal will be reflected, so the ultrasonic probe is used for defect detection of the dam body. Therefore, the ultrasonic probe is used to emit pulse signals to the dam body to obtain reflected signals of the pulse signals, the position of the dam body defect is determined according to the reflected signals of the pulse signals, the dam body defect position is detected in detail by the ultrasonic probe to obtain the depth and shape of the dam body defect, and finally the depth and shape of the dam body defect are analyzed to determine the influence of the dam body defect on the overall quality of the dam body.

[0068] Referring to Figure 2 As shown in the figure, based on the ultrasonic probe, the dam body internal defect detection to determine the dam body defect position specifically includes the following steps:

[0069] S101, based on the ultrasonic probe, emitting pulse signals to the dam body to obtain the reflection time of the pulse signals;

[0070] S102, obtaining the ultrasonic probe model and the dam body name;

[0071] S103, based on the remote control end, analyzing and calculating the reflection time of the pulse signals to determine the dam body defect position.

[0072] Referring to Figure 3 As shown in the figure, based on the remote control end, the reflection time of the pulse signals is analyzed and calculated to determine the dam body defect position, specifically including the following steps:

[0073] S1031, the remote control end extracts information from the database system according to the ultrasonic probe model to obtain related data of the ultrasonic probe;

[0074] S1032, the remote control end extracts information from the database system according to the dam body name to obtain related data of the dam body;

[0075] S1033, based on the remote control end, searching the related data of the dam body to obtain the material properties of the dam body;

[0076] S1034, the remote control end searches the related data of the ultrasonic probe according to the material properties of the dam body to obtain the propagation speed of the pulse signals;

[0077] S1035, the remote control end calculates and processes the reflection time of the pulse signal according to the propagation speed of the pulse signal, and obtains the dam defect position;

[0078] The specific calculation formula for obtaining the dam defect position is:

[0079]

[0080] In the formula, is the dam defect position; is the propagation speed of the pulse signal under the material properties of the dam; is the reflection time of the pulse signal;

[0081] In this embodiment, when the ultrasonic probe transmits a pulse signal to the entire dam and receives signals from the entire dam, the position of the reflected signal of the pulse signal is determined. After determining the position of the reflected signal of the pulse signal, information retrieval is performed on the database system according to the dam name to determine the relevant data of the dam when it was built, for example, the dam material properties. Because the propagation speed of the pulse signal in different media is different, the dam material properties need to be determined. After the dam material properties are determined, information retrieval is performed on the relevant data of the ultrasonic probe through the dam material properties to determine the propagation speed of the pulse signal of the ultrasonic probe under the dam material properties, and then the position of the dam defect inside the dam is obtained.

[0082] Referring to Figure 4 , the ultrasonic probe transmits a pulse signal multiple times to the inside of the dam according to the dam defect position, and the relevant data of the dam defect includes the following steps:

[0083] S201, based on the remote control end, unit grids around the dam defect position are divided to obtain multiple groups of unit grids;

[0084] S202, based on the remote control end, the multiple groups of unit grids are numbered to obtain numbered unit grids;

[0085] S203, based on the ultrasonic probe, the numbered unit grids are transmitted with a pulse signal to obtain the reflection time of the numbered pulse signal;

[0086] S204, the remote control end calculates and processes the reflection time of the numbered pulse signal and the propagation speed of the pulse signal to obtain the depth of the dam defect;

[0087] S205, the remote control end draws the defect shape according to the reflection time of the numbered pulse signal and the depth of the dam defect to obtain the shape of the dam defect;

[0088] In the embodiment, when the position of the dam defect is determined, the surrounding area of the dam defect position is divided to avoid data duplication and shorten the data processing time. If the surrounding area of the dam defect position is not divided into grids, the ultrasonic probe emits a pulse signal at the dam defect position, which will cause multiple reflection signals of the pulse signal, and the amount of data to be processed is too large. Therefore, the surrounding area of the dam defect position is divided into grids, and the range of the pulse signal emitted by the ultrasonic probe is adjusted. The ultrasonic probe emits a pulse signal to a unit grid. Even if a reflection signal of the pulse signal appears, it is the reflection signal of the unit grid, that is, there is a part of the dam defect in the unit grid. After all the unit grids are detected, the reflection signals of the pulse signals of all the unit grids are analyzed to determine the shape and specific depth of the dam defect.

[0089] Referring to Figure 5 The dam quality is determined based on the remote control end by analyzing and processing the related data of the dam defect, and specifically includes the following steps:

[0090] S301, the remote control end constructs a function according to the shape of the dam defect and the depth of the dam defect to obtain a defect similarity function;

[0091] S302, the remote control end calculates and processes the shape of the dam defect and the defect similarity function to obtain the volume of the dam defect;

[0092] S303, based on the remote control end, the shape of the dam defect is analyzed and processed to obtain the extension of the dam defect;

[0093] S304, based on the remote control end, the volume of the dam defect and the extension of the dam defect are compared and judged to determine the dam quality;

[0094] The specific calculation formula for obtaining the volume of the dam defect is:

[0095]

[0096] In the formula, is the volume of the dam defect; is the boundary of the three-dimensional area surrounded by the shape of the dam defect; is the defect similarity function;

[0097] In this embodiment, in order to more accurately calculate the volume of the dam defect, the defect similarity function corresponding to the shape of the dam defect is selected, and after the appropriate defect similarity function is selected, the volume of the dam defect is calculated. The shape of the dam body is different, and the influence on the overall quality of the dam body is also different. For example, a long crack will reduce the overall stress of the dam body. Therefore, the trend of the shape of the dam defect is analyzed, and the extension of the dam defect is determined. Finally, through comprehensive analysis of the extension of the dam defect and the volume of the dam defect, the quality of the dam is classified.

[0098] Referring to Figure 6 As shown in the figure, based on the remote control end, the volume of the dam defect and the extension of the dam defect are compared and judged to determine the quality of the dam, which specifically includes the following steps:

[0099] S3041, based on the remote control end, the volume of the dam defect, the extension of the dam defect and the set threshold value are compared and judged;

[0100] S3042, if the volume of the dam defect is greater than or equal to the set volume threshold value, and the extension of the dam defect is greater than or equal to the set extension threshold value, the quality of the dam is poor, etc.

[0101] S3043, if the volume of the dam defect is greater than or equal to the set volume threshold value, the extension of the dam defect is less than the set extension threshold value, or the volume of the dam defect is less than the set volume threshold value, and the extension of the dam defect is greater than or equal to the set extension threshold value, the quality of the dam is good, etc.

[0102] S3044, if the volume of the dam defect is less than the set volume threshold value, and the extension of the dam defect is less than the set extension threshold value, the quality of the dam is excellent.
