Therefore, the embodiment of the present invention can adjust the track distance as needed, so that the operation of the anchor-breaking equipment is not affected by the track distance, and it is flexible and convenient to use and has a wide range of applications.

[0062] In a specific embodiment, Figure 6 and Figure 7As shown, the anchor-breaking mechanical arm 4 includes a slewing assembly 4-1, a lifting arm 4-2 and a telescopic arm 4-4.

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

[0072] The broken anchor image is obtained by dividing the video data captured by the first depth camera 5-1 and / or the second depth camera 5-2 into frames.

[0073] S2, the electric control mechanism 3 inputs the broken anchor image into a pre-trained anchor lock recognition network deployed on its edge computer.

[0074] The specific composition structure of the anchor cable lock identification network is not specifically limited in the embodiment of the present invention. When it is implemented, a commonly used target recognition classification network can be used. In a specific embodiment, the anchor cable lock identification network uses an improved YOLOv8 model.

[0075] It should be noted that before inputting the broken anchor image into the pre-trained anchor cable lock recognition network, the anchor cable lock recognition network needs to be trained first. Specifically, when training the anchor cable lock recognition network, the following methods can be used:

[0076] S10. Collect data and create data sets.

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

[0078] Due to the complex environment of the excavation working face, the real-time monitoring scene of the anchor breaking process is often under low illumination and dusty fog conditions, so the original data set needs to be expanded. However, it is difficult to obtain image data in the harsh environment of the mine, so the original data set is enhanced. First, the image synthesis fog enhancement algorithm is used to generate images in a dusty fog environment; then, the image brightness darkening processing algorithm is applied to generate images in a low illumination environment. Finally, these three data sets (original data set, dusty fog data set, low illumination data set) are integrated together to form a more diverse comprehensive data set.

[0079] Next, the comprehensive data set is annotated, and the anchor locks in the comprehensive data set images are annotated using Labelimg annotation software. After the annotation is completed, the system automatically generates an XML format file corresponding to each image. The XML format file content records the annotation category, image size, and the size and position of the annotation box in detail.

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

[0081] Finally, the labeled dataset is divided into training set, validation set and test set in the ratio of 7:2:1.

[0082] S20. Build an improved YOLOv8 model as the anchor lock recognition network.

[0083] Specifically, the anchor lock identification network described in the embodiment of the present invention adopts an improved YOLOv8 model, which includes a backbone network module, a neck network module and a head network module. The output end of the backbone network module is connected to the input end of the neck network module, and the output end of the neck network module is connected to 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 with a C2f-MLCA module, and the PANet structure in the neck network module of the YOLOv8 model is replaced with a RepGFPN structure. The details are as follows:

[0084] S2.1. Improve C2f module.

[0085] The backbone network module of the YOLOv8 model is composed of a CBS module, a C2f module, and an SPPF module, wherein the C2f module contains many Bottleneck residual modules. These Bottleneck residual modules are connected in series to realize the extraction and fusion of features of different scales. However, the disadvantages of the Bottleneck residual module are also obvious. These Bottleneck residual modules cause the model to superimpose a large amount of information at the same position, and generate many redundant features in the process of obtaining key features, which may cause the loss of key information. Therefore, an embodiment of the present invention adds a lightweight attention mechanism module MLCA (mixed local channel attention) to the Bottleneck residual module, so that the key feature information extracted by it contains channel information, spatial information, local channel information and global channel information at the same time. The composition structure of the C2f-MLCA module is as follows: Figure 8 As shown. Fig. 9 As shown, (a) and (b) are schematic diagrams of the data processing process of Bottleneck and Bottleneck_MLCA ​​respectively.

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

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

[0088] S3.1, the input feature map is locally pooled in the spatial dimension through the LAP (local adaptive average pooling) operation.

[0089] Specifically, the input feature map of MLCA is a feature vector of shape C×W×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 through the LAP operation. After local pooling, the spatial dimension of the input feature map is compressed from W×H to ks×ks, and the shape of the output feature is C×ks×ks. This step retains the local spatial information and is used to capture fine-grained features.

[0090] S3.2, the local pooled features are divided into two parallel branches, the first branch performs GAP (global adaptive average pooling) operation and reshape operation on the local pooled features in turn; the second branch performs reshape operation on the local pooled features.

[0091] Specifically, the GAP operation converts the local pooled features into a vector of shape 1×C×ks×ks. The GAP operation retains the global feature information of the channel dimension while compressing the pooled spatial information 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 reshapes the local pooled features to ensure that the branch can retain the global features and prepare for the subsequent one-dimensional convolution operation.

[0092] S3.3, perform one-dimensional convolution (Conv1d) operation on the features after the reshaping operation of the two branches, perform UNAP operation on the features after the one-dimensional convolution operation of the first branch, and reshape the features after the one-dimensional convolution operation of the second branch again and fuse them with the features after the UNAP operation of the first branch through addition.

[0093] Specifically, both branches are operated through one-dimensional convolution (Conv1d), which can reduce 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 space and channel features. The second branch directly applies one-dimensional convolution operation to the global features after the reshaping operation to further extract global information.

[0094] The features after the one-dimensional convolution operation of the first branch are UNAPed (unpooled) to restore to the original spatial resolution C × W × 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 additive fusion not only contain the global context information (the second branch), but also combine the local spatial features (the first branch), making the feature expression richer and more comprehensive.

[0096] S3.4, perform UNAP operation on the features after addition fusion, and multiply fuse the features after UNAP operation with the input feature map to obtain the output of MLCA.

[0097] Specifically, the UNAP operation restores the fused features 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 features finally output by MLCA contain both channel attention information and integrate 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 branching architecture, which not only retains channel information, but also enhances the performance of the attention mechanism by introducing spatial features. It uses local pooling and global pooling, convolution and unpooling operations to improve the model's attention to spatial and channel information without significantly increasing the amount of computation. The data processing flow of MLCA is as follows: Fig.10 shown.

[0099] S2.2. Improve feature fusion network.

[0100] YOLOv8 uses PANet to fuse multi-scale feature maps in the neck network module. By adding an additional bottom-up path, accurate positioning information in the lower layer is used to enhance the entire feature hierarchy, thereby shortening the information path between high-level and low-level features. However, this bottom-up path design lacks the interaction between high-level semantic information and low-level spatial information, resulting in poor multi-scale detection results. To address this problem, an embodiment of the present invention proposes an improved efficient hierarchical aggregation network, RepGFPN, as an alternative 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 Fig.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 of different scales respectively and are suitable for multi-scale detection tasks. Fig.11 The upward slanting arrow in the figure indicates a 2x downsampling operation, which is used to extract more abstract semantic information at a higher level. The downward slanting arrow indicates a 2x upsampling operation, which is used to refine the spatial resolution and supplement the position information of the lower layer. The upsampling operation uses the nearest neighbor interpolation method 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: Fig.12 As shown, its input is 2 or 3 feature layers, which are divided into two branches after concat (connection), one branch passes through 1×1 convolution down channel, and the other branch passes through efficient layer aggregation network ELAN (efficient layer aggregation networks), and the two branches are concat again, and the output finally passes through 1×1 convolution down channel to obtain the final output. Specifically, when performing feature extraction and processing, the CSPStage includes:

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

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

[0105] 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 are processed multiple times by ELAM.

[0106] Specifically, the features of the first branch directly pass 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 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 through a RepConv. After RepConv, it passes through a convolution layer with a convolution kernel size of 3 (Conv K=3) to extract deeper spatial features. Then, an additive jump connection is used, which means that the input features and the results of Conv K=3 are additively fused.

[0108] After RepConv receives the input feature map, it divides the input feature map into two paths: Path 1, passes through a convolution 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 convolution layer with a kernel size of 1 and a stride of 2 (Conv2d K=1, s=2, p=0), followed by a BatchNorm2d layer. Then, the outputs of these two paths are 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. According to 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 enhancement method strength of 0.7, and Mixup data enhancement 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 the training is completed, the final improved YOLOv8 model is tested using the validation set to calculate its mAP (average precision), accuracy, recall and other indicators in the target detection task. The model weight performance under different iterations during the training process is compared, and the optimal model is selected for deployment. The detection accuracy of anchor locks is verified, and the model parameters or data enhancement strategies are further adjusted as needed to improve the generalization ability of the model and the actual application effect.

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

[0115] In a specific embodiment, the S3, when implemented, includes:

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

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

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

[0119] S32, predicting a bounding box and a confidence level for each grid using a fully connected layer of an anchor lock recognition network according to the feature vector of each grid.

[0120] For each grid, the anchor lock recognition network predicts one or more bounding boxes and outputs the following information: (1) Bounding box location: The model predicts the center position, width, and height of the anchor lock. This information is used to determine the exact location of the anchor lock in the image. (2) Category: Whether it is an anchor lock. (3) Confidence score: The confidence score indicates the possibility that the bounding box contains the anchor lock. The higher the score, the more confident the model is in the prediction result. This score consists of two parts: classification confidence and anchor lock existence confidence.

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

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

[0123] S4, the visually assisted 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 breaking instruction of 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 location of the anchor cable lock, he starts to operate the anchor breaking equipment to break the anchor. Specifically, the electric control mechanism 3 controls the hydraulic mechanism 2 to move the variable chassis 1 to a suitable position, and then continues to control the anchor breaking mechanical arm 4 to move the anchor breaker 4-8 to break the anchor.

[0127] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
