By installing a platform on the surface of the supporting side plate and the arc-shaped crossbeam, it is ensured that the grinding unit can be stably installed on the surface of the supporting frame; by providing an extrusion unit, wherein the extrusion unit pushes the positioning gear and the guide plate to rotate during the horizontal movement, thereby synchronously moving the push rod and the plate downward, pressing the metal parts covered by the cracks on the surface of the water conservancy pipeline body, reducing the danger that may be caused by manual pressing.

[0004] Although the device has many beneficial effects, the following problems still exist: when welding the metal parts against the pipeline to repair the leak, the operation steps are relatively cumbersome, which requires the staff to spend a lot of time to operate, and thus easily reduces the staff's work efficiency. In view of this, we propose a water conservancy project pipeline protection system. Summary of the invention

DETAILED DESCRIPTION

[0054] The present application is further described in detail below in conjunction with the accompanying drawings.

[0055] Reference Figure 1 The embodiment of the present application provides a water conservancy project pipeline protection system, the system comprising:

[0056] The acquisition module 6 is used to acquire images of pipelines used in water conservancy projects;

[0057] Annotation module 7, used for annotating the collected images;

[0058] Processing module 8, used for performing standardized preprocessing on the collected image data;

[0059] Extraction module 9, used for extracting feature representation from preprocessed image data;

[0060] Monitoring module 10, used for real-time monitoring of pipelines used in water conservancy projects;

[0061] The early warning module 11 is used to issue an early warning when water seepage occurs due to pipeline damage;

[0062] The storage module 12 is used to store corresponding data.

[0063] Reference Figure 1 The acquisition module 6 includes a camera 345, and the camera 345 is installed around the pipeline, so as to facilitate the acquisition and monitoring of the pipeline.

[0064] Specifically, data collection: cameras 345 are installed at key locations of water conservancy project pipelines to collect image data. Cameras 345 can monitor the status of the pipelines in real time and record image data.

[0065] Camera 345 can be connected to the monitoring center or cloud platform through the network. Camera 345 needs to have high definition and remote control functions to facilitate operation and data acquisition.

[0066] Reference Figure 1 The labeling module 7 includes a normal pipeline label and a damaged pipeline leakage and water spray label, which are used to classify and label the collected image data.

[0067] Specifically, data annotation is to mark or classify key information in the image. The collected image data is annotated and the normal and damaged water spraying conditions are classified and marked. For example, the image can be classified into normal pipelines and damaged pipelines with water seepage and water spraying. This part can be annotated manually or using automatic annotation technology.

[0068] Reference Figure 1 , the processing module 8 includes a denoising unit, an adjustment unit and a standardization unit;

[0069] A denoising unit, used to remove noise from the collected image data;

[0070] An adjustment unit, used for adjusting the image data to a uniform size;

[0071] A normalization unit used to make the pixel values ​​of an image have the same distribution.

[0072] Specifically, noise removal: The collected image data usually contains various noises, such as noise from the camera 345, motion artifacts, and poor lighting conditions. These noises may interfere with the training of the deep learning model, causing model misjudgment or performance degradation. Commonly used denoising methods include median filtering, Gaussian filtering, and mean filtering. This application uses the mean filtering method for denoising.

[0073] Resizing: Resizing all images to the same size can simplify the input of the model, making it easier for it to learn features in the image. Generally speaking, if the image size is too small, important information will be lost; if the image size is too large, the amount of computation and memory requirements will increase. Common sizes include 224x224, 256x256, or 512x512. Therefore, this application uses a size of 256x256 and a grayscale level of 16. The size of the image is 32KB, which can ensure important information while reducing computation and memory requirements.

[0074] Standardization: Standardization can make the pixel values ​​of an image have the same distribution. This is very important in deep learning because the model needs to be able to recognize data it has never seen. Common standardization methods include scaling pixel values ​​to between 0 and 1 or normalizing pixel values ​​to a normal distribution. This application uses scaling pixel values ​​to between 0 and 1.

[0075] Reference Figure 1 , the extraction module 9 includes a shape feature extraction unit, a color feature extraction unit and a texture feature extraction unit;

[0076] A texture feature extraction unit, used to extract texture features of the pipeline in the image;

[0077] A color feature extraction unit is used to help identify water marks around the leaking part in the image and compare them with normal conditions;

[0078] The shape feature extraction unit is used to determine the shape of the damaged part of the pipeline.

[0079] Specifically, texture features: Texture refers to the repetitive or regular structure in the image, which can be described by texture features; texture features can be used to distinguish between normal and damaged pipe spraying conditions. For example, damaged parts usually have irregular or diffuse textures, while normal parts are more uniform.

[0080] Shape features: Shape features describe the external contour and internal geometric structure of an object. When monitoring pipelines, shape features can be used to determine the shape and size of the damaged parts of the pipeline.

[0081] Deep convolutional neural networks (CNNs) detect different shape features, such as edges and corners, through convolutional layers and pooling layers. The convolutional layer can extract edge information, while the pooling layer can reduce the dimension of the feature map.

[0082] The superposition of multiple convolutional layers and pooling layers can gradually extract more complex shape features to help identify the crack morphology and size information of the pipeline.

[0083] Color features: Color is the wavelength and intensity of light reflected by an object. When monitoring pipelines, color features can be used to distinguish between normal and damaged water spraying conditions. Deep convolutional neural networks (CNNs) can detect different color features, such as color gradients and color histograms, through convolutional layers and pooling layers. These features can be used to describe the color distribution and changes of an image.

[0084] The extraction of color features can help identify water marks around the leaking parts of the pipe in the image and compare them with the normal conditions of the pipe, thereby further improving the accuracy of determining whether the pipe is leaking or spraying water.

[0085] Reference Figure 1 ,The monitoring module 10 uses a deep convolutional neural network CNN as a network model for real-time monitoring of the pipeline.

[0086] Specifically, the labeled dataset was divided into training set, validation set, and test set for training, validation, and testing the model in a ratio of 3:1:1. The labeled training set was used to train the monitoring model so that it could accurately identify damaged water spraying situations.

[0087] Reference Figure 1 , the early warning module 11 includes a first early warning unit and a second early warning unit;

[0088] The first warning unit includes an audible and visual alarm 4, and the audible and visual alarm 4 is installed around the pipeline to give an early warning when the pipeline is damaged;

[0089] The second warning unit is a remote warning, which is used to remotely send messages or information to relevant staff.

[0090] Specifically, when the model identifies a damaged pipe with water seepage and spraying, an early warning is activated;

[0091] Sound and light alarm: The sound and light alarm 4 emits sound and flashing light signals to remind people to pay attention to abnormal conditions in the pipeline. In the monitoring of water conservancy project pipelines, the sound and light alarm 4 can be set around the pipeline to monitor the abnormal conditions of the pipeline in real time and trigger the sound and light alarm when the warning conditions are met.

[0092] Remote push message: In the monitoring of water conservancy project pipelines, the remote push message function can be set to send notification information of abnormal situations to relevant personnel in a timely manner. Remote push messages can be implemented in a variety of ways, such as SMS, email, and mobile phone push. At the same time, remote push messages can also be integrated with other systems, such as linkage with external scheduling systems or maintenance systems, so as to take timely measures for repair or temporary blocking.

[0093] Reference Figure 1 , the storage module 12 includes a storage unit and a backup unit;

[0094] A storage unit for storing collection, preprocessing, monitoring and early warning information;

[0095] The backup unit is used to back up and restore the stored data.

[0096] Specifically, the storage unit may be a local disk, a solid-state drive, or a cloud database, so as to facilitate the storage of data;

[0097] Data backup and recovery: Data backup is an important means to ensure data security, and can be restored in the event of accidental data loss or damage. Common backup methods include manual backup and automatic backup. This application adopts an automatic scheduled backup strategy and encrypts and stores the backup data.

[0123] The implementation principle of a water conservancy project pipeline protection system in an embodiment of the present application is as follows: when protection is needed, the staff can set the installation ring 2 on the outside of the water pipe, and then start the first motor 351 through an external controller. The start of the first motor 351 can drive the rotating plate 352 to rotate. The rotation of the rotating plate 352 can push and pull the first connecting arm 358 through the second rotating shaft 359. When the first connecting arm 358 is pushed and pulled, it can drive the slide bar 356 to move along the direction of the installation sleeve 355. The movement of the slide bar 356 can drive the rack 357 to move. The movement of the rack 357 can drive the third gear 336 meshing with it to rotate. The rotation of the third gear 336 can drive the second rotating rod 325 to rotate. The rotation of the rod 325 can drive the second gear 326 to rotate, and the rotation of the second gear 326 can drive the gear ring 321 to rotate. The rotation of the gear ring 321 can drive the multiple first gears 323 meshed with it on its inner side to rotate. The rotation of the first gear 323 can drive the first rotating rod 322 to rotate. The rotation of the first rotating rod 322 can drive the eccentric wheel 324 to rotate. The rotation of the eccentric wheel 324 can drive the slide plate 313 to move in the direction away from the baffle 312. The movement of the slide plate 313 can squeeze the spring 315 and drive the slide bar 314 to move. The movement of the slide bar 314 can drive the connecting plate 316 and the abutment plate 317 to move in the direction close to the water pipe, so that the abutment plate 317 abuts against the water pipe. At the same time, when the rotating plate 352 rotates, the cooperation between the cam groove 364 and the mounting rod 363 can drive the second connecting arm 362 to swing around the third rotating shaft 361 as the axis. When the second connecting arm 362 swings, the cooperation between the first rotating shaft 353 and the fixing frame 354 can drive the mounting sleeve 355 to move downward. The downward movement of the mounting sleeve 355 can drive the sliding bar 356 and the rack 357 to move downward. At the same time, the second connecting arm 362 can drive the vertical plate 333 to move downward through the first rotating shaft 353. The downward movement of the vertical plate 333 can drive the positioning bar 335 to move downward, so that the positioning bar 335 is inserted into a tooth groove of the third gear 336 to lock the third gear 336, and the vertical plate 333 moves downward. The downward movement can drive the support plate 341 to move downward, and the downward movement of the support plate 341 can drive the mounting frame 342, the connecting shaft 343, the connecting frame 344 and the camera 345 to move downward, so that the fixing ring 1 and the mounting ring 2 can be quickly fixed on the outside of the water pipe. When the camera 345 detects that the water pipe is damaged and spraying water, the staff can stop the water supply or drainage, repeat the previous operation steps in reverse, separate the abutment plate 317 from the water pipe, and then move the mounting ring 2 outside the water pipe until the abutment plate 317 moves to the damaged part of the water pipe, and then repeat the previous operation steps to abut the abutment plate 317 against the damaged part of the water pipe for welding to repair the leak, thereby improving the convenience of using the device.
