TECHNICAL FIELD
[0001] The present application relates to the technical field of hydraulic protection, and in particular to a deep learning method for detecting corrosion of a hydraulic metal structure. BACKGROUND
[0002] Hydraulic metal structures (such as gates, pipelines, dam support structures, etc.) are exposed to a humid and corrosive environment for a long time, and are prone to corrosion problems. Corrosion not only reduces the strength of the structure, but also can cause safety hazards (such as gate failure, pipeline leakage), threatening the safety of water conservancy projects. In the traditional technology, the surface changes of the hydraulic metal structure are observed by manual visual observation to determine the corrosion condition of the hydraulic metal structure, which is low in efficiency.
[0003] The existing method for detecting corrosion of a hydraulic metal structure mainly collects the surface image of the hydraulic metal by an image collection device, and then constructs a detection model using deep learning technology to determine whether the pipeline surface is corroded. However, due to the complexity of the surface corrosion image of the hydraulic metal, the construction of the detection model is difficult, and the recognition process is complex, resulting in low detection efficiency and detection accuracy.
[0004] In summary, how to solve the problem of the existing method for detecting corrosion of a hydraulic metal structure, which has a large construction difficulty of the detection model and a complex recognition process, resulting in low detection efficiency and detection accuracy, has become a difficult problem to be solved in the field. Therefore, it is necessary to propose a more reasonable deep learning method for detecting corrosion of a hydraulic metal structure. SUMMARY
[0005] To solve the above problems, the present application provides a deep learning method for detecting corrosion of a hydraulic metal structure. By designing a mixed agent and improving the detection method, the corrosion area on the surface of the hydraulic metal can be quickly and accurately determined according to the fluorescence reflection while protecting the hydraulic metal, greatly reducing the detection difficulty and improving the detection efficiency and accuracy.
[0006] In order to achieve the above purpose, the technical scheme of the present application is as follows: a deep learning method for detecting corrosion of a hydraulic metal structure, comprising the following steps:
[0007] S1, pretreatment: preparing an anti-rust coating, a fluorescent agent and a comprehensive treatment device, mixing the anti-rust coating and the fluorescent agent by using the comprehensive treatment device to obtain a mixed agent; moving the comprehensive treatment device on the surface of the hydraulic metal while applying the mixed agent; and collecting the image of the surface of the hydraulic metal after applying the mixed agent by using the comprehensive treatment device to obtain an initial image.
[0008] S2, fluorescence reflection detection and corrosion analysis: during the use of the hydraulic metal, the comprehensive treatment device is used to move on the surface of the hydraulic metal; at the same time, the comprehensive treatment device is used to collect the current image of the surface of the hydraulic metal to obtain a current image, and the comprehensive treatment device is used to compare the current image with the initial image; the comprehensive treatment device identifies the corrosion area and the non-corrosion area on the surface of the hydraulic metal based on the reflected light of the fluorescent agent; if the reflected light of the fluorescent agent exists on the surface of the hydraulic metal, it indicates that the mixed agent in the area has not fallen off, and the comprehensive treatment device determines that the area has not been corroded; if the reflected light of the fluorescent agent is not identified on the surface of the hydraulic metal, it indicates that the mixed agent in the area has fallen off, and the comprehensive treatment device determines that the area has been corroded.
[0009] S3, corrosion treatment: when the comprehensive treatment device determines the corrosion area, the comprehensive treatment device scrapes the corrosion on the surface of the area and stores it; at the same time, new mixed agent is sprayed to the area; the comprehensive treatment device determines the corrosion severity according to the current image, and adjusts the spraying amount of the mixed agent according to the corrosion severity; the spraying amount of the mixed agent is proportional to the corrosion severity.

[0012] 2. In the prior art, the hydraulic metal needs to be detected and analyzed first, and then protected by other equipment and subsequent operation after obtaining the detection analysis result, resulting in untimely protection; in the present application, the protection and detection of the hydraulic metal are carried out synchronously, compared with the prior art, the hydraulic metal with corrosion can be protected in time, avoiding the corrosion of the corrosion area due to untimely treatment, resulting in more serious corrosion.

[0059] The collecting assembly comprises a plurality of cameras 24, the limiting rods 7 all extend out of the mounting groove on the side away from the connecting rods 6 and are all fixedly connected with the cameras 24 adjacent thereto by bolts, the rust treatment system is used for controlling the operation of the cameras 24.
[0060] The rust treatment system comprises a data acquisition module, a data analysis module and an intelligent control module; the modules are signal-connected with each other; the modules are all signal-connected with the remote control end (such as a mobile phone, a computer or a tablet, etc., a mobile phone is selected as the remote control end in the embodiment) of the operator.
[0061] The data acquisition module is used for collecting the initial image and the current image of the hydraulic metal by the cameras 24 and transmitting the images to the data analysis module.
[0062] The data analysis module constructs a corrosion analysis model based on deep learning algorithms. The corrosion analysis model is used to identify rusted and non-rusted areas based on the reflected light of the fluorescent agent in the current image, generate a corrosion area report, and transmit it to the intelligent control module. The corrosion analysis model is also used to compare the initial image and the current image of the hydraulic metal, determine the corrosion expansion rate based on the changes in the range of rusted areas and the shooting interval in the initial image and the current image, generate a corrosion change report, and transmit it to the intelligent control module.
[0063] The intelligent control module is used to extract the rusted areas of hydraulic metals based on the rusted area report, and to extract the rust and apply a mixture to the rusted areas; it also adjusts the amount of mixture applied based on the rust change report.
[0064] In this embodiment, the driving component is a geared motor 14.
[0065] The specific implementation process is as follows:
[0066] by Figure 1 For example, before the hydraulic metal is put into use, the operator can deliver the anti-rust coating and fluorescent agent into the mixing chamber 12 through the input pipe; then control the wall-climbing robot 1 to move vertically along the surface of the hydraulic metal through the mobile phone, and start the reduction motor 14 at the same time.
[0067] by Figure 3 For example, during this process, the reduction motor 14 will drive the right rotating rod 5 and the right first gear 16 to rotate counterclockwise around their own axis, which in turn will drive the right second gear 17 to rotate clockwise around its own axis. The right second gear 17 will then drive the left second gear 17 to rotate counterclockwise around its own axis, and drive the left first gear 16 and the left rotating rod 5 to rotate clockwise around their own axis. At this time, the rotating rod 5 will drive the stirring rod 13 to rotate, thereby mixing the anti-rust coating and fluorescent agent in the mixing chamber 12 to prepare a mixture.
[0068] by Figure 3 and Figure 4 For example, when the second gear 17 rotates clockwise, it drives the transmission rod 23 to rotate, which in turn drives the conveying gear 22 to rotate together. Utilizing the principle of a gear pump, as the tooth grooves above the conveying gear 22 change from an engaged state to a disengaged state, a partial vacuum is formed, drawing the mixture from the mixing chamber 12. As the tooth grooves below the conveying gear 22 change from a disengaged state to an engaged state, the volume of the area below the conveying gear 22 decreases, and the mixture in the conveying chamber is squeezed into the storage tank 18 by the conveying gear 22. Since the conveying chamber is located above the storage tank 18, the mixture is affected by gravity, making the conveying process smoother. During the rotation of the conveying gear 22, it also further improves the mixing effect of the anti-rust coating and the fluorescent agent.
[0069] by Figure 3 For example, when the rotating rod 5 rotates, it will also drive the connecting rod 6 and the limiting rod 7 to rotate. The limiting rod 7 will drive the camera 24 to rotate, thereby collecting images of various areas of the hydraulic metal surface. The data acquisition module will obtain preliminary images of the hydraulic metal surface through the camera 24 and transmit them to the data analysis module for subsequent judgment on whether the hydraulic metal surface is corroded.
[0070] Meanwhile, when the right limit rod 7 enters the right limit groove, it causes the center plate 4 and the center rod 3 to rotate 90° clockwise, at which point the left limit groove rotates upward; when the left limit rod 7 enters the left limit groove, it causes the center plate 4 and the center rod 3 to rotate 90° counterclockwise, at which point the right limit groove rotates upward; during the rotation of the center plate 4, the center plate 4 will drive the hinge rod 20 to move up and down, and the hinge rod 20 will drive the piston plate 19 to move up and down in the storage tank 18. At this time, the operator can open the control valve 21 through the mobile phone, and the mixture in the storage tank 18 will be squeezed by the piston plate 19 through the control valve 21 and sprayed onto the hydraulic metal surface.
[0071] At the same time, the rotation of the rotating rod 5 will drive the coating disk 8 to rotate. In conjunction with the movement of the wall-climbing robot 1, the mixture will be evenly coated onto the surface of the hydraulic metal by the coating disk 8, thereby protecting the hydraulic metal and facilitating subsequent inspection.
[0072] When inspecting the hydraulic metal after use, the operator can control the wall-climbing robot 1 to move vertically along the surface of the hydraulic metal via a mobile phone, while simultaneously starting the reduction motor 14.
[0073] During the movement of the wall-climbing robot 1, the connecting rod 6, the limiting rod 7, and the camera 24 will rotate under the drive of the rotating rod 5. The data acquisition module will acquire the current image of the hydraulic metal surface through the camera 24 and transmit it to the data analysis module. The data analysis module will compare the current image with the initial image and determine whether there is corrosion at the current position.
[0074] During the rotation of the central rod 3, the central rod 3 will also drive the telescopic rod 9 and the scraper 10 to rotate. In the initial state, the telescopic rod 9 is in a retracted state. If the data analysis module determines that there is rust in the current area, the intelligent control module will control the telescopic rod 9 to extend, so that the scraper 10 is in contact with the surface of the hydraulic metal, thereby scraping the rust on its surface into the collection frame 11, and using the magnetic sheet to adsorb the rust, which is convenient for subsequent operators to conduct further inspection of the rust. At the same time, the intelligent control module will open the control valve 21 to spray the mixture into the area, and use the application plate 8 to spread the mixture evenly.
[0075] The corrosion analysis process is as follows: the data analysis module uses the corrosion analysis model to detect corrosion on the surface of the hydraulic metal; the corrosion analysis model identifies the corrosion area and the non-corrosion area of the surface of the hydraulic metal based on the reflected light of the fluorescent agent; if the surface of the hydraulic metal has fluorescent reflection, it indicates that the mixed agent in the area has not fallen off, and the corrosion analysis model determines that the area has not been corroded; if the surface of the hydraulic metal does not identify fluorescent reflection, it indicates that the mixed agent in the area has fallen off, and the corrosion analysis model determines that the area has been corroded; and the corrosion analysis model compares the initial image and the current image, and determines the change rate of the corrosion area according to the area difference of the corrosion area and the time interval between the two image acquisitions.
[0076] The calculation formula of the change rate is as follows:
[0077] V=S / T (1).
[0078] Wherein, S is the area difference of the corrosion area in the initial image and the current image; T is the acquisition time interval of the initial image and the current image, and V is the change rate; the greater the change rate V, the more serious the corrosion.
[0079] The embodiment can quickly and accurately determine the corrosion area on the surface of the hydraulic metal according to the fluorescent reflection while protecting the hydraulic metal, greatly reducing the detection difficulty and improving the detection efficiency and accuracy through the design of the mixed agent and the improvement of the detection idea.
[0080] Embodiment 2:
[0081] As shown in the accompanying drawings, Figure 2 different from the above-mentioned embodiments, a protective frame 25 for protecting the rotating rod 5 and the center rod 3 is welded outside the mounting groove; the protective frame 25 is provided with a telescopic groove for the telescopic rod 9 to extend and retract, and a plurality of smearing grooves for the smearing disc 8 to rotate; and a smearing plate 26 for further smearing the mixed agent is welded on the outer side wall of the protective frame 25.
[0082] The specific implementation process is as follows: during the movement of the wall-climbing robot 1, the protective frame 25 can protect each component in the mounting groove and improve the stability of the device; when the wall-climbing robot 1 moves, the smearing plate 26 can further smear the mixed agent smeared on the smearing disc 8, so that the mixed agent on the surface of the hydraulic metal is more uniform.
[0083] Obviously, the above-mentioned embodiments are only examples for clear illustration, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
