[0066] Figure 2 This is a schematic diagram of the structure of a high-quality communication system for wireless communication modules within the region of this invention. Detailed Implementation
[0067] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0068] This invention provides a high-quality communication method for wireless communication modules within a specific area, referring to... Figure 1 , Figure 1 This is a flowchart illustrating a high-quality communication method for a wireless communication module within a specified area according to an embodiment of the present invention.
[0069] In this embodiment, a high-quality communication method for a wireless communication module within a certain area is provided, the method comprising the following steps:
[0070] S1: Collect industrial site images of the target area, and extract several key elements and element feature information of each key element from the industrial site images;
[0071] S2: Obtain the communication node feature information of each communication node configured with a wireless communication module within the target area; construct a communication node knowledge graph of the target area based on the communication node feature information; combine the element feature information with the communication node knowledge graph to generate an enhanced knowledge graph.
[0072] S3: The graph structure data of the enhanced knowledge graph is learned by using a graph neural network with an attention mechanism to capture the deep-level association between communication nodes and key elements, and to obtain the communication quality prediction requirements of each communication node output by the graph neural network; wherein, the communication quality prediction requirements include several dimensions of communication requirement parameters.
[0073] S4: Based on the communication quality demand parameters of several dimensions in the communication quality prediction demand, and according to the influence mapping relationship between the communication quality demand parameters and different communication resources, solve the communication resource configuration scheme for each communication node;
[0074] S5: According to the communication resource configuration scheme, perform communication resource configuration for the wireless communication module of each communication node within the area, and realize industrial field communication based on the communication resource configuration results.
[0075] It should be noted that industrial sites are characterized by a variety of equipment, high personnel mobility, and dynamic material allocation. The communication needs of communication nodes (such as various sensors, control terminals, and gateways) change dynamically with the surrounding environment (personnel distribution, equipment operating status, material location, etc.). Traditional communication resource scheduling methods often rely on preset rules or passive feedback mechanisms based on network status, failing to fully explore the deep-seated relationships between communication nodes and key elements (equipment, personnel, materials, etc.) in the industrial scenario. This results in insufficient timeliness and accuracy of resource scheduling, making it difficult to adapt to the dynamically changing industrial environment, and consequently affecting communication quality and the overall operational efficiency of industrial automation systems.
[0076] To address the aforementioned issues, this embodiment extracts key elements and element feature information from industrial site images, integrates them into the communication node knowledge graph of the target area, forming an enhanced knowledge graph. A graph neural network incorporating an attention mechanism is then used to learn the graph structure data of this enhanced knowledge graph, capturing the deep-level relationships between communication nodes and key elements to obtain predicted communication quality requirements. Furthermore, based on the influence mapping relationship between communication quality requirement parameters and different communication resources, a communication resource configuration scheme for each communication node is solved, thereby executing industrial site communication. Thus, this invention, by accurately capturing the dynamic changes and characteristics of equipment, personnel, and materials in industrial scenarios and employing a combination of knowledge graph fusion and graph neural networks, achieves advance prediction of changes in communication requirements, ensuring the stability and efficiency of system communication.
[0077] In a preferred embodiment, the steps of acquiring industrial site images of the target area and extracting several key elements and element feature information of each key element from the industrial site images specifically include:
[0078] S11: Receive industrial site images collected and transmitted by several image acquisition devices deployed in the target area, and use image semantic segmentation to identify and extract several key elements and element features of each key element in the industrial site images.
[0079] S12: For each identified key element, extract the element feature vector from its element features to generate element feature information for each key element; wherein, the key element includes at least one of equipment element, personnel element, and material element, the element features include element location coordinates, element quantity, and element activity status, and the element feature vector includes feature parameters of several dimensions.
[0080] In this embodiment, industrial scene images collected and transmitted by distributed cameras within the target area are first received. Image semantic segmentation technology is used to accurately identify and extract key elements and element features in the images. Furthermore, element feature vectors are extracted to form structured element feature information. Through multi-device collaborative acquisition and semantic segmentation, the problem of incomplete identification caused by the large variety and scattered distribution of elements in industrial scenes is solved. At the same time, unstructured images are transformed into structured feature vectors to ensure that scene information can be efficiently integrated with communication node data, thereby improving the richness and accuracy of subsequent maps.
[0081] In practical applications, image semantic segmentation is used to identify and extract several key elements and the element features of each key element from industrial site images. The specific steps include:
[0082] S111: Input the received industrial site images into the U-Net architecture deep learning model, perform pixel-level classification on the images, and identify at least one key element among equipment elements, personnel elements, and material elements, as well as the element features of each key element;
[0083] The U-Net architecture deep learning model uses a loss function that combines cross-entropy loss, Dice loss, and smoothing loss during training, and its specific expression is as follows:
[0084] ;
[0085] In the formula, This represents the loss function used during training of the U-Net architecture deep learning model. Represents cross-entropy loss, This indicates Dice's loss. Indicates smoothing loss. , These are the weighting coefficients.
[0086] In this embodiment, the acquired industrial site images are input into the U-Net architecture deep learning model. The symmetrical encoder-decoder structure of U-Net achieves pixel-level classification, accurately identifying key elements and features such as equipment (e.g., robotic arms, AGVs), personnel (e.g., operators), and materials (e.g., vehicle parts, electronic component trays). Simultaneously, to improve model segmentation accuracy, a joint loss function is used during training. Cross-entropy loss optimizes the overall error of the classification task, Dice loss addresses the pixel imbalance between foreground (e.g., small materials) and background (e.g., the ground) in industrial scenes, and smoothing loss reduces jagged errors at segmentation boundaries, resulting in more accurate element edge recognition. Compared to traditional semantic segmentation models, U-Net has stronger pixel-level classification capabilities. Combined with the joint loss function, it solves the problem of missed identification of small elements due to class imbalance and optimizes segmentation boundary accuracy, significantly improving the accuracy of key element recognition and providing high-quality data for subsequent feature extraction.
[0087] In a preferred embodiment, the step of acquiring communication node feature information for each communication node configured with a wireless communication module within the target area, and constructing a communication node knowledge graph for the target area based on the communication node feature information, specifically includes:
[0088] S21: Collect the node attribute information of each communication node in the target area that is equipped with a wireless communication module in advance, and generate the node feature vector of each communication node as the communication node feature information.
[0089] S22: Construct edges between communication nodes based on physical connection associations, functional associations, and data flow associations, and calculate edge weights by combining communication frequency, communication data volume, and communication data dependency.
[0090] S23: Construct a knowledge graph of communication nodes for the target region based on the set of communication nodes consisting of all communication nodes, the set of edges consisting of all edges, and the set of edge weights consisting of all edge weights.
[0091] In practical applications, the expression for calculating edge weights is as follows:
[0092] ;
[0093] In the formula, This represents the edge weight between communication nodes i and j. This indicates the communication frequency between communication nodes i and j. This represents the amount of data communicated between communication nodes i and j. This represents the data dependency between communication nodes i and j. , , These are the weighting coefficients.
[0094] In this embodiment, node attribute information (such as device type, function, location coordinates, and communication protocol) of all communication nodes (such as sensors, control terminals, and gateways) configured with wireless communication modules within the target area is collected in advance. These attributes are then transformed into multi-dimensional node feature vectors as communication node feature information. Based on the actual associations between communication nodes, edges between nodes are constructed, including physical connection associations (such as the communication connection between sensors and gateways), functional associations (such as gateways relying on sensor data to implement control functions), and data flow associations (such as data flowing from sensors to gateways). The weight of each edge is calculated by combining communication frequency, communication data volume, and communication data dependency. Finally, the communication node set V, edge set E, and edge weight set W are integrated to construct a communication node knowledge graph that reflects the strength of node associations. .
[0095] It should be noted that when calculating edge weights, the communication frequency, communication data volume, and data dependency between the two communicating nodes are considered to set the appropriate weights. , , As a weighting coefficient (summing up to 1, it can be adjusted according to the needs of industrial scenarios, such as scenarios with high real-time requirements), (It can be set to 0.5 to enhance the influence of frequency), quantifying the information of the three dimensions of communication frequency (dynamic interaction strength), data volume (transmission load), and dependency (functional correlation tightness) into edge weights, accurately reflecting the correlation strength between nodes.
[0096] Therefore, by visualizing the dispersed communication nodes in the form of a graph, the strength of the association between nodes is clearly quantified, avoiding the blind resource scheduling caused by the ambiguity of node relationships in traditional methods, and providing a structured communication network model for subsequent integration with scene elements.
[0097] Based on this, the step of combining the element feature information with the communication node knowledge graph to generate an enhanced knowledge graph specifically includes:
[0098] S24: For the element feature vector corresponding to the element feature information Dimensionality reduction is performed, and the reduced element feature vectors are... Communication node feature vector corresponding to communication node feature information Perform feature concatenation to construct a fused feature vector. And perform normalization processing;
[0099] S25: Generate corresponding element nodes for each key element, and automatically identify and match communication nodes and element nodes that meet the matching rules according to the preset matching rules, and generate associated edges between communication nodes and element nodes that meet the matching rules.
[0100] S26: Based on the communication node feature vector of each communication node and the element feature vector of each key element Calculate the cosine similarity and Euclidean distance between each communication node and each key element, and calculate the weights according to the preset weight coefficients as the weights of the associated edges.
[0101] S27: Construct an enhanced knowledge graph of the target region based on the node set consisting of communication nodes and element nodes, the set of associated edges consisting of all associated edges, and the set of associated edge weights consisting of all associated edge weights.
[0102] In this embodiment, the element feature vectors are dimensionality reduced (e.g., using PCA algorithm) to avoid the curse of dimensionality caused by high-dimensional features. The dimensionality-reduced vectors are then concatenated with the communication node feature vectors to generate a fused feature vector. Normalization (e.g., Min-Max normalization) is used to unify the data scale. After this, corresponding element nodes are generated for each key element and added to the original communication node knowledge graph. Then, based on preset matching rules (e.g., the control range of the communication node covers the element node's location, and the element's function matches the communication node's function), communication nodes and element nodes are automatically identified and matched, generating association edges between the matched nodes. Finally, the association edge weights are calculated: the cosine similarity (measuring feature similarity, such as the compatibility between device type and control terminal) and Euclidean distance (measuring location proximity, such as the distance between a sensor and material) are calculated between the communication node and element node, and their weighted sum is calculated using preset weight coefficients as the association edge weights. Finally, the node sets of communication nodes and element nodes are integrated. The set of edges of primary edges and associated edges and the weight set of the original edge weight and the associated edge weight. Generate augmented knowledge graphs .
[0103] Therefore, this invention, through feature fusion and the construction of associated edges, enables the knowledge graph to not only contain communication network relationships, but also reflect the impact of scene dynamics on communication, providing rich structural data for subsequent graph neural networks to capture scenes and communication associations.
[0104] In a preferred embodiment, the step of learning the graph structure data of the enhanced knowledge graph using a graph neural network incorporating an attention mechanism to capture the deep-level relationships between communication nodes and key elements, and obtaining the communication quality prediction requirements for each communication node output by the graph neural network, specifically includes:
[0105] S31: Construct an initial multi-layer graph neural network, using historical communication quality parameters of the target area and key element feature data extracted from industrial site images of the same period as the training set, with the training objective of minimizing prediction error, and train the multi-layer graph neural network using the training set;
[0106] The specific expression for the training loss function is as follows:
[0107] ;
[0108] In the formula, To predict communication demand, For actual communication needs, i represents the i-th communication node, and N represents the total number of communication nodes. Represents the vector norm;
[0109] S32: Combine the fused feature vector at the current time step. As initial node features By utilizing a trained multi-layer graph neural network combined with an attention mechanism, and employing a layer-by-layer node feature propagation and aggregation approach, the features of the nodes in the previous layer are utilized. Deriving the node features of the next layer ;
[0110] The expression derived using a multi-layer graph neural network combined with an attention mechanism is as follows:
[0111] ;
[0112] ;
[0113] In the formula, For attention weights, For attention magnitude, ∥ represents the feature concatenation operation. For activation function, For the neighboring nodes of communication node i in the augmented knowledge graph connected by edges or associated edges, For the first Layer trainable weight matrix, For activation functions;
[0114] S33: Based on the final node features obtained in the last layer, predict the communication quality requirements of the output communication node in the next time step by performing linear transformation and activation on the feature vector of each communication node. .
[0115] In this embodiment, during the model training phase, a multi-layer graph neural network is constructed. The training set uses historical communication quality parameters of the target region (such as rate, latency, and packet loss rate over the past 6 months) and industrial site element features (such as equipment operating status and personnel distribution during the same period). The objective is to minimize the L2 norm between predicted and actual communication demands, and the model is trained until convergence. During the demand prediction phase, the fused feature vector at the current moment is used as the initial node features of the graph neural network. The trained model, combined with an attention mechanism, updates node features through layer-by-layer node feature propagation and aggregation. Layer node features Perform linear transformation and activation to output the multi-dimensional communication quality prediction requirements for each communication node at the next time step.
[0116] Therefore, by applying the attention mechanism, the model can focus on key associations (such as prioritizing the association between the control terminal and the corresponding device), avoiding the limitation of traditional graph neural networks that treat all neighbor nodes equally. By combining historical scenarios and communication data for training, the model can capture the potential patterns between scenario dynamics and communication needs, significantly improving the prediction accuracy of communication quality requirements.
[0117] In a preferred embodiment, the communication quality requirement parameters in the predicted communication quality requirements include: communication transmission rate, communication transmission delay, and communication packet loss rate; the communication resources include communication bandwidth parameters, communication power parameters, and communication frequency parameters.

[0128] S42: Generate a communication resource configuration scheme for each communication node based on the communication bandwidth parameters, communication power parameters, and communication frequency parameters of each communication node.
[0129] In this embodiment, based on the linear relationship between communication transmission rate and bandwidth, the communication bandwidth parameters under the communication quality prediction requirements are calculated. Then, based on the characteristic that communication transmission delay is jointly determined by data transmission time, power attenuation time, and physical layer base delay, the communication power under the communication quality prediction requirements is calculated based on the solved communication bandwidth parameters and the communication transmission delay under the communication quality prediction requirements. Finally, based on the characteristic that communication transmission packet loss rate is negatively correlated with power and frequency interference cleanliness, the communication frequency parameters under the communication quality prediction requirements are calculated based on the solved communication power and the communication transmission packet loss rate under the communication quality prediction requirements.
[0130] Therefore, this invention transforms abstract communication requirements into specific resource parameters through a quantified mapping relationship, avoiding resource waste (such as over-configuration of bandwidth) or insufficiency (such as excessive latency due to low power) caused by traditional experience-based configuration, and achieving precise resource matching.
[0131] In a preferred embodiment, according to the communication resource configuration scheme, communication resource configuration is performed for the wireless communication module of each communication node within the area. Based on the communication resource configuration results, industrial field communication steps are implemented, specifically including:
[0132] S51: Extract the communication bandwidth parameters, communication power parameters, and communication frequency parameters of each communication node recorded in the communication resource configuration scheme;
[0133] S52: Send the communication bandwidth parameters, communication power parameters, and communication frequency parameters of each communication node to the wireless communication module of the corresponding communication node, drive each communication node to configure the communication configuration parameters of the wireless communication module, and realize industrial field communication based on the configuration results.
[0134] In this embodiment, the core configuration parameters of each communication node—communication bandwidth, communication power, and communication frequency—are extracted from the communication resource configuration scheme to form a structured configuration instruction (e.g., JSON format: {"node_id":"C1","bandwidth":"8MHz","power":"4dBm","frequency":"2.4GHz"}). This instruction is then sent to the wireless communication module of the corresponding communication node via an industrial bus (e.g., RS485) or a wireless gateway. After receiving the instruction, the module automatically adjusts its internal parameters (e.g., adjusting the bandwidth, power, and frequency of the RF module). Once the configuration is complete, high-quality communication in the industrial field (e.g., transmission of equipment control commands and production data feedback) can be achieved, ultimately resulting in a stable improvement in the communication quality of the industrial field.
[0135] This invention proposes a high-quality communication method for wireless communication modules within a regional area. By fusing image semantic segmentation with knowledge graphs, it accurately captures the dynamic changes of equipment, personnel, and materials in industrial scenarios. Combined with a graph neural network using an attention mechanism, it enables advance prediction of communication needs, avoiding resource scheduling lags caused by traditional passive feedback. Simultaneously, it employs resource allocation based on quantized mapping relationships to achieve optimal matching of bandwidth, power, and frequency, reducing resource consumption when communication modules are idle or have low communication demand. In the long term, this can reduce energy costs and module wear in industrial systems.
[0136] On the other hand, dynamically adjusting the resource configuration of the wireless communication module enables on-demand configuration and precise adaptation, while minimizing interference with other nodes. This ensures that multi-node communication within the area is mutually non-interfering and transmits efficiently, guaranteeing that the overall communication quality indicators (rate, latency, packet loss rate) within the area meet the high requirements of industrial automation scenarios.
