DETAILED DESCRIPTION

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1 As shown, a method for detecting the quality of a dam body of a water conservancy project comprises: S100, using an ultrasonic probe to detect defects inside the dam body and determine the locations of the defects in the dam body; S200, the ultrasonic probe transmits pulse signals to the inside of the dam body multiple times according to the position of the dam body defect to obtain relevant data of the dam body defect, wherein the relevant data of the dam body defect includes the shape of the dam body defect and the depth of the dam body defect; S300, based on the remote control terminal, analyzing and processing the relevant data of the dam body defects to determine the quality of the dam body; Those skilled in the art can understand that when the pulse signal emitted by the ultrasonic probe encounters a defect, the pulse signal will be reflected. Therefore, the ultrasonic probe is used to detect defects in the dam body. Therefore, the ultrasonic probe is first used to emit a pulse signal to the entire dam body to obtain a reflected signal of the pulse signal. The position of the dam body defect is determined based on the reflected signal of the pulse signal. The ultrasonic probe is then used to carefully detect the position of the dam body defect to obtain the depth and shape of the dam body defect. Finally, the depth and shape of the dam body defect are analyzed to determine the impact of the dam body defect on the overall quality of the dam body.

[0021] Reference Figure 2 As shown, based on the ultrasonic probe, the defect detection inside the dam body is carried out to determine the location of the dam body defects, which specifically includes the following steps: S101, using an ultrasonic probe, transmitting a pulse signal into the interior of the dam body to obtain a reflection time of the pulse signal; S102, obtaining the ultrasonic probe model and the dam body name; S103: Based on the remote control terminal, the reflection time of the pulse signal is analyzed and calculated to determine the defect position of the dam body.

[0022] Reference Figure 3As shown, based on the remote control terminal, the reflection time of the pulse signal is analyzed and calculated to determine the location of the dam defect, which specifically includes the following steps: S1031, the remote control terminal extracts information from the database system according to the ultrasonic probe model to obtain relevant data of the ultrasonic probe; S1032, the remote control terminal extracts information from the database system according to the dam body name to obtain relevant data of the dam body; S1033. Based on the remote control terminal, information retrieval is performed on the relevant data of the dam body to obtain the material properties of the dam body; S1034, the remote control terminal performs information retrieval on relevant data of the ultrasonic probe according to the material properties of the dam body, and obtains the propagation speed of the pulse signal; S1035. The remote control terminal calculates and processes the reflection time of the pulse signal according to the propagation speed of the pulse signal to obtain the defect position of the dam body; Among them, the specific calculation formula for obtaining the defect position of the dam body is:

[0023] In the formula, is the defect location of the dam body; is the propagation speed of the pulse signal under the material properties of the dam body; is the reflection time of the pulse signal; In this embodiment, when the ultrasonic probe transmits a pulse signal to the entire dam body, the signal is received by the entire dam body to determine the position of the reflected signal of the pulse signal. After the position of the reflected signal of the pulse signal is determined, information is retrieved from the database system according to the name of the dam body to determine relevant data during the construction of the dam body, such as the material properties of the dam body. Because the propagation speed of the pulse signal in different media is different, it is necessary to determine the material properties of the dam body. After the material properties of the dam body are determined, information is retrieved from the relevant data of the ultrasonic probe through the material properties of the dam body to determine the propagation speed of the pulse signal of the ultrasonic probe under the material properties of the dam body, thereby obtaining the position of the dam body defect inside the dam body.

[0024] Reference Figure 4 As shown, the ultrasonic probe transmits pulse signals to the inside of the dam body multiple times according to the defect position of the dam body, and the acquisition of relevant data of the dam body defect specifically includes the following steps: S201, based on the remote control terminal, performing unit grid division around the defect position of the dam body to obtain multiple groups of unit grids; S202, based on the remote control terminal, performing numbering processing on multiple groups of unit grids to obtain numbered unit grids; S203, using an ultrasonic probe, transmitting a pulse signal to the numbered unit grid to obtain a reflection time of the numbered pulse signal; S204, the remote control terminal 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 body defect; S205, the remote control terminal draws the defect shape according to the reflection time of the numbered pulse signal and the depth of the dam body defect to obtain the shape of the dam body defect; In this embodiment, after the location of the dam body defect is determined, the surrounding area of ​​the dam body defect is divided to avoid data duplication and shorten the data processing time. If the surrounding area of ​​the dam body defect is not grid-divided, the ultrasonic probe transmits a pulse signal to the dam body defect, which will cause multiple pulse signal reflection signals to appear, and the amount of data to be processed is too large. Therefore, the surrounding area of ​​the dam body defect is grid-divided, and then the range of the ultrasonic probe transmitting the pulse signal is adjusted. The ultrasonic probe transmits a pulse signal to the unit grid. Even if a pulse signal reflection signal appears, it is the reflection signal of the unit grid, that is, there are partial dam body defects inside the unit grid. After all unit grids are detected, the reflection signals of the pulse signals of all unit grids are analyzed to determine the shape and specific depth of the dam body defect.

[0025] Reference Figure 5 As shown, based on the remote control terminal, the relevant data of dam body defects are analyzed and processed to determine the dam body quality, which specifically includes the following steps: S301, the remote control end constructs a function according to the shape and depth of the dam body defect to obtain a defect similarity function; S302, the remote control end performs calculation processing according to the shape of the dam body defect and the defect similarity function to obtain the volume of the dam body defect; S303, based on the remote control terminal, analyzing and processing the shape of the dam body defect to obtain the extension of the dam body defect; S304, based on the remote control terminal, comparing and judging the volume of the dam body defect and the extension of the dam body defect to determine the quality of the dam body; Among them, the specific calculation formula for obtaining the volume of dam body defects is:

[0026] In the formula, is the volume of the dam body defect; The boundary of the three-dimensional area enclosed by the shape of the dam body defect; is the defect similarity function; In this embodiment, in order to more accurately calculate the volume of the dam body defect, the defect similarity function corresponding to the shape of the dam body defect is selected. After the appropriate defect similarity function is selected, the volume of the dam body defect is calculated. Different shapes of the dam body have different effects on the overall quality of the dam body. For example, a longer crack will reduce the overall stress of the dam body. Therefore, the direction of the shape of the dam body defect is analyzed to determine the elongation of the dam body defect. Finally, the quality of the dam body is graded by comprehensively analyzing the elongation of the dam body defect and the volume of the dam body defect.

[0027] Reference Figure 6 As shown, based on the remote control terminal, the volume of the dam body defect and the elongation of the dam body defect are compared and judged, and the dam body quality is determined in the following specific steps: S3041. Based on the remote control terminal, compare and judge the volume of the dam body defect, the extension of the dam body defect and the set threshold value; S3042: If the volume of the dam body defect is greater than or equal to the set volume threshold, and the elongation of the dam body defect is greater than or equal to the set elongation threshold, the dam body quality is poor; S3043. If the volume of the dam body defect is greater than or equal to the set volume threshold, the elongation of the dam body defect is less than the set elongation threshold, or the volume of the dam body defect is less than the set volume threshold, the elongation of the dam body defect is greater than or equal to the set elongation threshold, the dam body quality is good, etc.; S3044. If the volume of the dam body defect is smaller than the set volume threshold, and the elongation of the dam body defect is smaller than the set elongation threshold, the dam body quality is excellent.
