[0064] Specifically, when the anchor breaking mechanical arm 4 is performing anchor breaking operation, the electric control mechanism 3 first controls the slewing assembly 4-11 to rotate to a certain position; then the electric control mechanism 3 and the hydraulic mechanism 2 control the lifting oil cylinder 4-3 to lift to a suitable position, further control the telescopic oil cylinder 4-5 to extend to a certain length, and control the first swing oil cylinder 4-6 and the second swing oil cylinder 4-7 to rotate to a certain angle, so that the anchor breaker 4-8 is in a suitable anchor breaking position, and the pose adjustment of the anchor breaker 4-8 when it is docked with the anchor cable lock is realized.

[0070] The anchor breaking method of the anchor breaking equipment with the variable chassis and the visual auxiliary lock positioning function also comprises the following steps S1 to S5.

[0071] S1, the electric control mechanism 3 acquires the anchor breaking image collected by the visual auxiliary positioning mechanism.

[0072] The anchor breaking image is obtained by frame division of video data collected by the first depth camera 5-1 and / or the second depth camera 5-2.

[0073] S2, the electric control mechanism 3 inputs the anchor breaking image into a pre-trained anchor cable lock identification network deployed on an edge computer of the electric control mechanism 3.

[0074] The specific component structure of the anchor cable lock identification network is not limited in the embodiment of the application, and a common target identification classification network can be used in specific implementation. In one specific embodiment, the anchor cable lock identification network uses an improved YOLOv8 model.

[0075] It should be noted that the anchor cable lock identification network needs to be trained before the anchor breaking image is input into the pre-trained anchor cable lock identification network. Specifically, when training the anchor cable lock identification network, the following method can be used:

[0076] S10, collect data and make a data set.

[0077] First, the first depth camera 5-1 and the second depth camera 5-2 installed in the well are used to collect video data of the anchor cable lock, and the recorded video data is frame by frame split into pictures to form an original data set.

[0078] Due to the complex environment of the tunneling working face, in the real-time monitoring scene of the anchor breaking process, it is often in low-illumination and dusty fog conditions, so it is necessary to expand the original data set. However, it is difficult to obtain image data in a harsh underground environment, so the original data set is processed by data enhancement. First, an image synthesis fog enhancement algorithm is used to generate images in a dusty fog environment; then, an image brightness darkening processing algorithm is used to generate images in a low-illumination environment. Finally, the three data sets (the original data set, the dusty fog data set and the low-illumination data set) are integrated together to form a more diversified comprehensive data set.

[0079] Next, the comprehensive data set is labeled, specifically using Labelimg labeling software to label the anchor cable lock in the comprehensive data set image. After labeling, the system automatically generates an XML format file corresponding to each image, and the XML format file content records the labeling category, image size, and the size and position of the labeling box in detail.

[0080] In order to facilitate subsequent model training, the XML file is uniformly converted into a TXT format. The TXT file will serve as a label data set, and the TXT file content contains several five-tuples (the number depends on the number of labeling boxes in the image). The first element of the five-tuple is the category information, and the last four elements are the coordinates of the two end points of the normalized labeling box, and the specific position of the labeling box can be determined through the two end points.

[0081] Finally, the label data set is divided into a training set, a validation set and a test set according to a 7:2:1 ratio.

[0082] S20, build an improved YOLOv8 model as an anchor cable lock identification network.

[0083] Specifically, the anchor cable lock identification network in the embodiment of the application adopts an improved YOLOv8 model, the improved YOLOv8 model includes a backbone network module, a neck network module and a head network module, the output end of the backbone network module is connected with the input end of the neck network module, and the output end of the neck network module is connected with the input end of the head network module; the improvement scheme is: based on the YOLOv8 network model structure, the C2f module in the backbone network module is replaced by the C2f-MLCA module, and the PANet structure in the neck network module of the YOLOv8 model is replaced by the RepGFPN structure. Specifically as follows:

[0084] S2.1, improve the C2f module.

[0085] The backbone network module of the YOLOv8 model is composed of a CBS module, a C2f module and a SPPF module, wherein the C2f module contains many Bottleneck residual modules, and the concatenation of these Bottleneck residual modules can realize the extraction and fusion of features of different scales. However, the Bottleneck residual module also has obvious shortcomings. These Bottleneck residual modules make the model superimpose a large amount of information at the same position, produce a lot of redundant features in the process of obtaining key features, and may cause the loss of key information. Therefore, a lightweight attention mechanism module MLCA (mixed local channel attention) is added in the Bottleneck residual module in the embodiment of the application, so that the key feature information extracted by it contains channel information, spatial information, local channel information and global channel information, and the composition structure of the C2f-MLCA module is as follows:Figure 8 As shown in FIG. 1, the input feature map is first processed by the Bottleneck and Bottleneck_MLCA. Figure 9 As shown in FIG. 1, the input feature map is first processed by the Bottleneck and Bottleneck_MLCA.

[0086] The MLCA is designed to make up for the deficiency of the traditional channel attention mechanism in capturing spatial feature information. Unlike the attention mechanism that only focuses on channel information, the MLCA contains not only channel feature information but also spatial feature information. The following is a detailed description of the MLCA processing data.

[0087] In one specific embodiment, when the MLCA processes data, it includes:

[0088] S3.1, the input feature map is locally pooled in the spatial dimension by the LAP (Local Adaptive Average Pooling) operation.

[0089] Specifically, the input feature map of the MLCA is a feature vector with a shape of C x W x H, where C is the number of channels, and W and H are the spatial dimensions (width and height). The input feature map is locally pooled in the spatial dimension by the LAP operation. After local pooling, the spatial dimension of the input feature map is compressed from W x H to ks x ks, and the shape of the output feature is C x ks x ks. This step preserves the local spatial information and is used to capture fine-grained features.

[0090] S3.2, the locally pooled feature is divided into two parallel branches, the first branch sequentially performs GAP (Global Adaptive Average Pooling) operation and reshaping (Reshape) operation on the locally pooled feature; the second branch performs reshaping operation on the locally pooled feature.

[0091] Specifically, the GAP operation converts the locally pooled feature into a vector with a shape of 1 x C x ks x ks. The GAP operation preserves the global feature information of the channel dimension and compresses the spatial information of the pooling into a more compact representation. The purpose of the reshaping operation is to adapt to the subsequent one-dimensional convolution operation. The second branch directly performs reshaping operation on the locally pooled feature to ensure that this branch can preserve the global feature and prepare for the subsequent one-dimensional convolution operation.

[0092] S3.3, one-dimensional convolution (Conv1d) operation is performed on the features after the reshaping operation of the two branches, and UNAP operation is performed on the features after the one-dimensional convolution operation of the first branch, and the features after the one-dimensional convolution operation of the second branch are reshaped again and fused with the features after the UNAP operation of the first branch by addition.

[0093] Specifically, both branches are operated by a one-dimensional convolution (Conv1d) operation, which can reduce the computational complexity and further extract sequence or channel information. The one-dimensional convolution operation of the first branch is used to capture the complex relationship between local spatial and channel features. The one-dimensional convolution operation is directly applied to the global features after the reshaping operation in the second branch, further extracting global information.

[0094] The features after the first branch one-dimensional convolution operation are subjected to a UNAP (unpooling) operation to restore the original spatial resolution C x W x H. The UNAP operation ensures that the feature map of this branch matches the input feature map in the spatial dimension.

[0095] The features after the addition fusion not only contain global context information (second branch), but also combine local spatial features (first branch), making the feature expression more comprehensive.

[0096] S3.4, UNAP operation is performed on the features after the addition fusion, and the features after the UNAP operation are multiplied with the input feature map to obtain the output of the MLCA.

[0097] Specifically, the UNAP operation makes the fused features further restore to a higher spatial resolution for more effective feature expression. The role of multiplication fusion is to highlight key features and suppress redundant information. The final output features of the MLCA contain both channel attention information and global and local spatial features, making the model pay more attention to important information.

[0098] In summary, MLCA combines local and global spatial information with channel attention through a branch architecture, preserving channel information while enhancing attention mechanisms by introducing spatial features. It uses local and global pooling, convolution, and unpooling operations to improve the model's attention to spatial and channel information without significantly increasing computational complexity. The data processing flow of the MLCA is shown in Figure 10 .

[0099] S2.2, improve the feature fusion network.

[0100] YOLOv8 uses PANet to fuse multi-scale feature maps in the neck network module, which increases an additional bottom-up path to enhance the entire feature hierarchy using accurate positioning information in the low layer, thereby shortening the information path between high and low layer features. However, this bottom-up path design lacks interaction between high-level semantic information and low-level spatial information, resulting in suboptimal multi-scale detection. To address this issue, the present embodiment proposes an improved efficient hierarchical aggregation network, RepGFPN, as an alternative solution for the neck network module.

[0101] RepGFPN solves the above problems through skip connection structure and cross-scale connection, and effectively integrates multi-scale features. Its network structure is as follows Figure 11 As shown in the figure, P3-in, P4-in, and P5-in represent the feature maps from the three input layers, respectively. The processed intermediate feature maps are P4-hid and P5-hid, which are extracted and processed by the multi-scale fusion module (CSPStage). The feature maps of the output layer are P3-out, P4-out, and P6-out, which output features at different scales and are suitable for multi-scale detection tasks. Figure 11 The upward-diagonal arrow in the figure indicates a 2x downsampling operation, which is used to extract more abstract semantic information at a higher level. The downward-diagonal arrow indicates a 2x upsampling operation, which is used to refine the spatial resolution and supplement the position information at the lower level. The upsampling operation uses nearest neighbor interpolation to restore spatial details, thereby improving detection accuracy while maintaining computational efficiency.

[0102] In a specific embodiment, the RepGFPN performs feature extraction and processing through CSPStage when processing data; the CSPStage structure is as follows: Figure 12 As shown, its input is 2 or 3 feature layers. After concat (connection), it is divided into two branches. One branch passes through a 1×1 convolutional reduction channel, and the other branch passes through an efficient layer aggregation network (ELAN). The two branches are concat again, and the output finally passes through a 1×1 convolutional reduction channel to obtain the final output. Specifically, the CSPStage includes the following when performing feature extraction and processing:

[0103] S3-1, perform a concatenation operation on the input features and divide the concatenated features into two branches.

[0104] Specifically, CspStage receives the input feature map and splits the input into two branches through a Concat operation.

[0105] In S3-2, the features of the first branch pass through a convolution layer with a convolution kernel size of 1; the features of the other branch first pass through a convolution layer with a convolution kernel size of 1, and then pass through ELAM for multiple processing.

[0106] Specifically, the features of the first branch pass directly through a convolution layer with a kernel size of 1 (Conv K = 1), which is equivalent to adjusting the number of channels without changing the spatial dimension. The features of the other branch pass through a convolution layer with a kernel size of 1 (Conv K = 1), and then are processed multiple times by ELAM (repeated N times).

[0107] After receiving a feature map input, ELAM first passes it through a RepConv layer. Following RepConv, it passes through a convolutional layer with a kernel size of 3 (Conv K=3) to extract deeper spatial features. Next, an additive skip connection is used to additively fuse the input features with the results of Conv K=3.

[0108] After receiving the input feature map, RepConv divides it into two paths: Path 1 passes through a convolutional layer with a kernel size of 3 and a stride of 2 (Conv2d K=3, s=2, p=1), followed by a BatchNorm2d layer and a ReLU activation function. Path 2 passes through a convolutional layer with a kernel size of 1 and a stride of 2 (Conv2d K=1, s=2, p=0), followed by a BatchNorm2d layer. The outputs of these two paths are then fused together through an addition operation to form the final output.

[0109] S3-3, after fusing the features of the two branches through the connection operation, a convolution layer with a convolution kernel size of 1 is used to merge the processed feature maps and output the final result.

[0110] S30, model training and optimization.

[0111] First, the training parameters are set. Based on the characteristics of the dataset and the computing power and video memory of the hardware device, the training parameters are set as follows: images of 640×640 pixels, 16 images per batch, 300 iterations, Adam optimizer, initial learning rate of 0.001, momentum value of 0.937, Moasic data augmentation method strength of 0.7, and Mixup data augmentation method strength of 0.5.

[0112] Secondly, the training set is input into the improved YOLOv8 model for iterative training, and verification is performed at the completion of each iteration. The weight file of the current model and the best model weight file in the previous training are saved. When the training reaches the set number of iterations, the training is ended and the best model weight file is saved.

[0113] Finally, after training, the final improved YOLOv8 model was tested on the validation set, calculating metrics such as mAP (mean average precision), accuracy, and recall for the object detection task. The performance of model weights at different training iterations was compared, and the optimal model was selected for deployment. Its detection accuracy for anchor locks was verified, and model parameters and data augmentation strategies were further adjusted as needed to improve the model's generalization and practical application effectiveness.

[0114] S3, anchor lock identification network analysis and output of the anchor lock position.

[0115] In one specific embodiment, the S3 comprises, in particular implementation:

[0116] S31, the anchor cable lock identification network divides the broken anchor image into SxS grids, and extracts the feature vector of each grid through its feature extraction network.

[0117] Specifically, the broken anchor image is divided into SxS grids, realizing the decomposition of the broken anchor image into multiple small areas, and each grid is responsible for detecting one or more anchor cable locks that may exist in the broken anchor image. If the center point of the anchor cable lock falls into a certain grid, the grid will be responsible for predicting the position of the anchor cable lock. Through this division method, the anchor cable lock identification network can detect multiple anchor cable locks in parallel, and ensure that good detection results can be obtained even in complex scenes.

[0118] The feature extraction network is a convolutional neural network, which is responsible for extracting features at different levels from the broken anchor image. These feature vectors not only contain the boundary information of the anchor cable lock, but also capture the detailed features of the anchor cable lock, such as color, texture, and shape, etc. The continuous application of convolutional layers enables the model to identify objects in the image from local to global while maintaining computational efficiency.

[0119] S32, according to the feature vector of each grid, the anchor cable lock identification network predicts the boundary box and the confidence for each grid using the fully connected layer of the anchor cable lock identification network.

[0120] For each grid, the anchor cable lock identification network predicts one or more boundary boxes and outputs the following information at the same time: (1) Boundary box position: the model predicts the center position, width and height of the anchor cable lock, which is used to determine the exact position of the anchor cable lock in the image. (2) Category: whether it is an anchor cable lock. (3) Confidence score: confidence represents the possibility that the boundary box contains an anchor cable lock, the higher the score, the more confident the model is about the prediction. This score is composed of two parts: classification confidence and anchor cable lock existence confidence.

[0121] S33, select the boundary box with the highest confidence, and remove the repeated boundary box through the non-maximum suppression algorithm to obtain the target box where the anchor cable lock is located, and take the target box as the position of the anchor cable lock.

[0122] This step can avoid repeated detection of the same anchor cable lock, thereby ensuring that each anchor cable lock is only marked by a unique boundary box.

[0123] S4, the visual auxiliary positioning mechanism displays the position of the anchor cable lock.

[0124] Specifically, the video display 5-3 in the visual auxiliary positioning mechanism displays the position of the anchor cable lock, so that the operator can observe the position of the anchor cable lock from the video display 5-3.

[0125] S5, when the anchor cable lock is obtained, the anchor cable lock is broken through the cooperation of the electric control mechanism 3, the hydraulic mechanism 2 and the anchor breaking mechanical arm 4.

[0126] When the operator determines the position of the anchor cable lock, the anchor breaking equipment is operated to start the anchor breaking operation. Specifically, the variable chassis 1 is controlled to move to a suitable position by operating the electric control mechanism 3 to control the hydraulic mechanism 2, and then the anchor breaking mechanical arm 4 is controlled to move, so that the anchor breaking device 4-8 breaks the anchor.

[0127] The above is only the preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection scope of the present application.
