Abstract
Description
Technical Field
[0001] This invention relates to the field of digital twin and artificial intelligence fusion technology, specifically to a digital human configuration method and system based on industrial metaverse digital twins. Background Technology
[0002] With the vigorous promotion of the construction of intelligent industrial systems and the development of digital twin applications combined with artificial intelligence, industrial production efficiency can be significantly improved, achieving cost reduction and efficiency enhancement. As enterprises focus on building metaverse applications, how to enhance industrial productivity, reduce human resource costs, and improve product quality has become an urgent issue to be addressed.
[0003] Currently, existing solutions for improving the efficiency of digital human configuration involve pre-producing digital humans or dynamically generating them according to needs, enabling rapid and diversified configuration to ultimately improve the accuracy of digital human models and allow for the free replacement of various functional configurations. However, in factories across different industries, processes vary greatly, and generalized solutions contain too much redundancy, making them difficult to integrate with specific industries. Furthermore, the lack of targeted intelligent processing during development means that the costs of intelligent model retrieval and learning remain high, resulting in limited efficiency improvements and difficulties in reusing intelligent modules. Therefore, reducing the costs of intelligent model learning and retrieval, and increasing the efficiency of reusable configuration, has become a key research focus in this field.
[0004] Patent document CN119917951A (application number: 202411784849.2) discloses a digital twin system based on multimodal recognition. By integrating equipment, a digital twin, and an information transmission medium, it achieves multimodal information acquisition, processing, fusion analysis, and feedback control. The system uses a multimodal signal acquisition device to collect various modal information, and performs data fusion analysis and scenario simulation through a simulator and a large multimodal model to guide the equipment execution subject to perform precise operations. It possesses intelligent learning and adaptability, and can update its professional knowledge base through manual teaching and filter uncertainties using a knowledge graph. In this technical solution, the digital human module is a general-purpose design, without optimization for appearance configurations of special industrial tooling (such as safety helmets and protective gloves), resulting in insufficient model adaptability. The motion library mainly consists of standard industrial robot motions, lacking refined motion data for special working conditions such as high-temperature smelting and heavy machinery operation, resulting in incomplete coverage of industrial scenarios. It does not achieve dynamic binding between the digital human's behavioral logic and real-time production data, and cannot automatically adjust the interaction strategy according to the equipment status.
[0005] Patent document CN119884388A (application number: 202411902560.6) discloses a digital human interaction method, system, medium, and product program based on knowledge graphs. It constructs a multi-layered knowledge structure to achieve digital human reasoning interaction, optimizing the limitations of cross-domain knowledge processing, and realizing multi-turn dialogue through hierarchical association of the knowledge graph. However, in this technical solution, knowledge representation is not integrated with 3D virtual scenes, making it impossible to visualize the internal structure of equipment and the location of faults. It does not integrate speech synthesis and action generation modules, limiting the interaction method to text-based question and answer. Furthermore, it does not consider industrial environmental noise interference, resulting in a significant improvement in speech recognition accuracy within industrial manufacturing scenarios.
[0006] Patent document CN120259500A (application number: 202510325920.9) discloses a method and system for digital human generation and streaming. Based on the ER-NERF algorithm, it generates and streams a 2.5D digital human model through depth estimation and light radiation field reconstruction of multi-view image data. During data transmission, model parameters and texture information are pushed to the user terminal in streaming media format. The terminal decodes and reconstructs the model in real time and performs dynamic rendering. However, this technical solution suffers from insufficient stereoscopic depth in the 2.5D modeling, failing to meet the spatial positioning accuracy requirements of complex industrial scenarios. While the streaming latency is optimized to 150ms, it still exceeds the user's patent requirement of 100ms for industrial-grade performance, indicating room for improvement in real-time performance. Furthermore, the lack of an integrated industrial knowledge graph means the digital human lacks professional decision-making capabilities such as equipment fault diagnosis, resulting in limited interaction depth.

[0090] Specifically, the digital human model supports remote collaboration;
[0091] The digital human model supports remote collaboration by: constructing a virtual 3D model of on-site industrial equipment, using the virtual 3D model to reflect the operating status of the on-site industrial equipment in real time, thereby constructing a metaverse space;
[0092] The system acquires the operator's physical movements, postures, and position information, and converts these information into the state of the on-site operator's digital model in the metaverse space in real time. It then converts the state of the on-site operator's digital model into three-dimensional space operation commands, and realizes real-time response of the virtual three-dimensional model based on these commands.

[0094] Specifically, the method further includes:
[0095] Based on the production tasks of the industrial production line, and using multiple historical planning simulation schemes, a comprehensive optimal solution is generated by scoring based on a multi-objective decision-making algorithm.
[0096] Based on the generated comprehensive optimal solution, instructions are issued through edge computing nodes. When production fluctuations occur in the production line equipment, production fluctuations are responded to through real-time rescheduling or resource coordination.
[0097] The real-time rescheduling includes: responding to production fluctuations by invoking process compensation rules in the knowledge graph;
[0098] The resource coordination includes: responding to production fluctuations by reallocating paths through a distributed task scheduling algorithm.
[0099] Specifically, the method further includes: using a digital human model to perform a three-dimensional dynamic demonstration of the standard operating procedures of industrial production equipment, thereby achieving safety training; at the same time, during the three-dimensional dynamic demonstration, a visual interface is used to display the internal status of the equipment and text prompts for key operating points.

The digital human model compares and analyzes the captured movements with a standard motion library. Based on the comparison and analysis results, it performs operations including real-time correction, motion decomposition, and stress testing.
[0101] The present invention also provides a digital human configuration system based on an industrial metaverse digital twin. The digital human configuration system based on an industrial metaverse digital twin can be implemented by executing the process steps of the digital human configuration method based on an industrial metaverse digital twin. That is, those skilled in the art can understand the digital human configuration method based on an industrial metaverse digital twin as a preferred embodiment of the digital human configuration system based on an industrial metaverse digital twin.
[0102] Example 2
[0103] Example 2 is a preferred example of Example 1.
[0104] According to the present invention, a digital human configuration method based on an industrial metaverse digital twin is provided, such as... Figure 2 As shown, it includes:
[0105] Step 1: Digital Human Model Construction and Training;
[0106] Specifically, step 1 includes:
[0107] Step 1.1: Appearance Configuration. Using voice, text, and images, a highly realistic digital human model is generated based on the image of an industrial manufacturing worker. The current model has rich details, including facial expressions and body movements. At the same time, various work clothes and tools, such as safety helmets and wrenches, are added to the digital human to make it conform to the industrial production scenario.
[0108] Step 1.2: Behavior Configuration. Collect a large amount of standard operating actions in the manufacturing process in industrial scenarios, such as equipment maintenance and parts assembly, and accurately record them using motion capture equipment. Use deep learning algorithms to train these action data and build a motion library for the digital human. For example, use a recurrent neural network (RNN) combined with a long short-term memory network (LSTM) to learn and optimize the action sequences, enabling the digital human to perform various operating actions accurately and naturally, with a significant improvement in action execution accuracy.
[0109] Step 1.3: Voice Configuration. Acquire voice data from the industrial manufacturing scenario, including equipment operating sounds and operator commands. Preprocess the acquired voice data to efficiently remove background noise, resulting in preprocessed voice. Use a Transformer-based speech recognition model to recognize the preprocessed voice, building a voice library for the digital human. Simultaneously, configure multiple voice modes for the digital human, such as normal operation mode and emergency alarm mode, to meet the voice interaction needs in different scenarios. For example, in the event of equipment failure, the digital human can issue warning messages with a rapid voice and specific alarm tone, reminding operators to handle the situation promptly.
[0110] Step 1.4: Knowledge base configuration. Integrate industrial manufacturing process knowledge, equipment maintenance manuals, fault diagnosis cases, and other information to construct a knowledge graph. Through natural language processing technology, transform this knowledge into a form that the digital human can understand and use. For example, associate equipment fault phenomena with possible causes and solutions. When the digital human receives abnormal equipment information, it can quickly perform fault diagnosis and recommend solutions based on the knowledge graph.
[0111] Step 1.5: Train the digital human model using the digital human action library, digital human speech library, and knowledge graph to obtain the trained digital human model.
[0112] Step 2: Implementation of intelligent operation and maintenance functions for digital humans;
[0113] Specifically, step 2 includes:
[0114] Step 2.1: Real-time monitoring and early warning. The digital human connects to the equipment data acquisition system to monitor the operating status of the production line equipment in real time, for example, with a sampling frequency of 1kHz. The system inputs the collected parameters such as vibration, temperature, and current into the digital human model for anomaly detection. When an abnormal pattern is detected, a multimodal early warning is immediately triggered.
[0115] The multimodal early warning includes:
[0116] Visual warning: The digital human flashes a red light and points to the faulty part in the twin scene;
[0117] Voice alert: Employs an emergency alarm voice mode, for example: the speech rate is significantly increased compared to normal, the tone is raised several times, and the message "Industrial production line, vibration frequency exceeds the threshold, temperature is abnormal" is broadcast.
[0118] Data push: Automatically retrieves several historical similar cases associated with the knowledge graph, with an alert response time of less than 1 second.
[0119] Step 2.2: Fault Diagnosis and Repair Guidance: Construct a knowledge graph-driven inference engine to achieve intelligent processing of the entire fault handling process.
[0120] Fault location: After receiving abnormal data from the equipment, the fault characteristics are matched in the knowledge graph using the SPARQL Protocol and RDF QueryLanguage; for example, "abnormal increase in cutting torch current → unstable arc → nozzle blockage";
[0121] Solution generation: Based on entity relationships in a knowledge graph, such as "nozzle blockage → solution = replace nozzle + clean channel", a repair solution is automatically generated, which includes 3D animation, tool list, and safety precautions.
[0122] Interactive guidance: The digital human assists in maintenance in the following ways:
[0123] Augmented reality annotation: Overlaying AR arrows onto physical devices to indicate the disassembly sequence;
[0124] The voice prompts step by step: "Step 1: Close the gas supply valve of the cutting torch. Step 2: Use a special wrench to remove the nozzle..."
[0125] Knowledge Q&A: Provides real-time answers to operators' questions and retrieves a list of required operation descriptions from the knowledge graph.
[0126] Effect Verification: After the repair is completed, the digital human automatically verifies the repair effect through sensor data and acceptance criteria in the knowledge graph.
[0127] Step 2.3: Remote Collaboration: In the process of handling complex faults, the digital human supports remote collaboration.
[0128] On-site operators use head-mounted displays and on-site cameras to transmit digital models of industrial equipment and personnel to remote experts via AR / VR, 3D projection, and other devices. Experts, using sensors, can manipulate the on-site models with gestures, performing various auxiliary functions such as 3D spatial movement, zooming, burst splitting, and projection of 3D holographic digital avatars of on-site personnel. They can guide on-site personnel in repairs by observing faulty models and through voice communication, and can also provide timely corrections by observing the actions of the on-site personnel's holographic digital avatars.
[0129] On-site operators can use AR / VR head-mounted displays and voice connection devices to listen to explanations and demonstrations from remote experts, effectively aiding communication and operational demonstrations. For example, for high-altitude or internal structural equipment, live video cannot provide aerial guidance or simulate the explosion and disassembly of real-world equipment; therefore, digital humans and digital models become particularly important, significantly improving the efficiency of remote collaboration.
[0130] Step 3: Digital Human Scheduling, Execution, and Monitoring;
[0131] Step 3.1: Industrial Metaverse Pre-scheduling: The digital human performs virtual scheduling simulations in the industrial metaverse twin space, optimizing production instructions through the following process:
[0132] Multi-scheme simulation: For production tasks on industrial production lines, based on multiple historical simulation schemes, a comprehensive optimal solution is generated using a multi-objective decision-making algorithm. This provides a pre-selected optimal solution for industrial production and refining, characterized by short processing time, high capacity, low personnel requirements, and low energy consumption. The digital robot explains this pre-selected solution to the operators and provides a comparison score with other pre-selected solutions.
[0133] Efficiency First: Maximize equipment utilization by using digital robots to calculate vehicle paths and industrial production line transfer sequences.
[0134] Energy consumption optimization: Through knowledge graphs, digital humans call process parameters to simulate energy consumption under different parameter combinations.
[0135] Solution optimization: The digital human calls a multi-objective decision-making algorithm for scoring and automatically recommends the best comprehensive solution, with a pre-test time of less than 5 minutes.
[0136] The process of generating a comprehensive optimal solution for the production tasks of an industrial production line, based on multiple historical planning simulation schemes and a multi-objective decision-making algorithm, includes:
[0137] The production tasks of the industrial production line are obtained, and the obtained production tasks are processed including edge transformation and feature extraction to obtain the processed production tasks.
[0138] Based on the processed production tasks, similar solutions are selected from the historical database and a candidate set is generated;
[0139] The candidate solutions are evaluated for multiple objectives, and the optimal solution is selected through a scoring function.
[0140] Specifically, the optimization objective function is defined, including: maximizing production efficiency, minimizing configuration cost, minimizing response latency, and maximizing resource utilization balance.
[0141]
[0142] in, The weights are determined by experts based on historical scenarios and the current situation; This indicates maximizing production efficiency; This indicates that the configuration cost is minimized; This indicates that the response latency is minimized; This indicates that the balance of resource utilization is maximized.
[0143] Step 3.2: Virtual-Real Interaction Execution and Control: The digital human acts as the central hub for virtual-real interaction, enabling precise coordination between the physical system and the virtual space.
[0144] Command issuance: The pre-optimized scheduling command is issued through the edge computing node (ECS).
[0145] Dynamic adjustment: Digital humans respond to production fluctuations through the following mechanisms:
[0146] Real-time rescheduling: When the raw material composition fluctuates, the digital human calls the process compensation rules in the knowledge graph to adjust the oxygen supply intensity of the converter.
[0147] Resource coordination: When a driving conflict is detected, the digital human visualizes the conflict point in the twin scene and reallocates the path through a distributed task scheduling algorithm.
[0148] If a conflict occurs in the operation of multiple trains, the algorithm reads all subsequent routes of all trains, automatically recalculates all new planned routes for all trains, assigns new routes, and finally displays the new planned route configuration scheme.
[0149] Process visualization: The digital human presents its execution status in three modes within a twin scenario:
[0150] Global dashboard: Real-time updates on the progress of each process.
[0151] Local drilling: Click on the equipment model to display detailed parameters.
[0152] Historical review: Supports replaying the scheduling process at any time period.
[0153] Step 4: Implement the digital human quality detection function;
[0154] Step 4.1: Real-time Inspection: On the production line of industrial equipment, the digital human performs real-time quality inspection of products by working collaboratively with inspection equipment. When the equipment passes by the inspection equipment, the digital human system immediately acquires the inspection data and analyzes and judges it using a quality inspection model.
[0155] Step 4.2: Defect Marking and Feedback: Once a defect is detected in the industrially refined product, the digital robot precisely marks the defect location on the product image through a visual interface and feeds the defect information back to the production operators. Simultaneously, the digital robot provides corresponding handling suggestions based on the defect type and severity, such as rework or scrapping. For minor welding defects, the digital robot recommends manual repair by the operators; for severe functional defects, the digital robot instructs that the product be scrapped directly.
[0156] Step 4.3: Quality Statistics and Analysis: The digital human system performs real-time statistics and analysis on the inspection data, generating quality reports and trend charts. Through in-depth analysis of quality data, it helps companies identify potential quality problems in the production process and optimize production techniques and procedures. By analyzing quality data over a period of time, if a high defect rate is found in a particular production stage, the company can make targeted improvements and training to the equipment, processes, or operators in that stage, thereby improving overall product quality.
[0157] Step 5: Safety Training for Operating Digital Human Devices
[0158] Step 5.1: Equipment Operation Demonstration: The digital human provides a 3D dynamic demonstration of the standard operating procedures for key industrial production equipment. In the virtual scene, the operating procedures for key industrial production equipment are demonstrated dynamically in 3D by the digital human. The demonstration includes pre-start checks, parameter settings, normal operating procedures, and shutdown protocols (e.g., operating in the order of "stop feeding first → then cooling → finally shutting off gas"). During the demonstration, the internal status of the equipment is visualized and key operating points are displayed simultaneously. The demonstration video has a frame rate ≥120fps, and the motion reproduction accuracy error is ≤2°.
[0159] Step 5.2: Motion Guidance: The trainee's movements are captured in real-time using a motion capture system (sampling frequency 120Hz). The digital human then compares and analyzes these movements against a standard motion library (comparison latency ≤200ms). Three levels of guidance are provided for deviations:
[0160] Real-time correction: When a dangerous action is detected (such as starting the equipment without closing the safety door), vibration feedback is immediately triggered and a voice prompt is given: "Danger! Please perform a safety check first."
[0161] Motion decomposition: Complex operations (such as ladle turntable positioning) are broken down into 8 basic motion units, which are demonstrated step by step by a digital human and compared in real time with joint angles.
[0162] Stress test: Simulate emergency response training under extreme conditions (such as sudden power outages or sensor malfunctions) to assess the trainees' accuracy in completing safe procedures within 30 seconds.
