Description

Technical Field

[0001] The present application relates to the field of electrical digital data processing, and in particular to a universal digital twin method, system, equipment and medium for tunneling working faces. Background Art

[0002] Digital twins digitally create dynamic, multi-dimensional, multi-disciplinary, and multi-physical-quantity virtual models of physical entities to simulate and characterize the physical entities' attributes, behaviors, and rules in real-world environments. Due to their unique capabilities, including virtual-reality integration and real-time interaction, iterative operation and optimization, and comprehensive, full-factor, full-process, and full-business data-driven capabilities, digital twins are currently being applied across all stages of the equipment lifecycle, including design, manufacturing, and maintenance, to improve performance, reliability, and efficiency. In the case of a tunneling face, digital twin technology can construct a virtual model of the face that reflects various real-world status information, such as geological conditions, equipment operating status, and personnel activity, in real time. This digital twin model enables simulation and analysis of the face, predicting potential problems and risks and providing decision support for actual tunneling operations.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0017] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] In an exemplary embodiment, the present application provides a general digital twin method for a tunneling working face, which is executed by a computer device, specifically a terminal or a server, or a terminal and a server. In the embodiment of the present application, the method is applied to a server as an example for explanation. Figure 1 As shown, the method includes: Step 100: Acquire trial operation configuration parameters or tunneling operation configuration parameters. Trial operation configuration parameters include the specifications of the tunnel to be excavated, the attributes of the tunneling equipment to be used, and the proposed operating parameters of the tunneling equipment. Tunneling operation configuration parameters include the specifications of the tunnel during the tunneling process, the attributes of the tunneling equipment to be used, and the operating parameters of the tunneling equipment.

[0019] Step 101: construct a model database, and retrieve a three-dimensional model corresponding to the tunneling equipment in the trial operation configuration parameters or the tunneling operation configuration parameters from the model database.

[0020] Step 102: Generate a pilot production digital twin of the tunneling face based on the trial run configuration parameters and the retrieved corresponding 3D model. This step primarily allows users to simulate the current mining plan based on the set tunnel specifications and tunneling equipment after they have determined the tunnel to be mined. This allows users to adjust the plan based on actual mining needs.

[0021] Step 103: Generate a real-time digital twin of the tunneling face based on the tunneling operation configuration parameters and the retrieved corresponding 3D model. This step is primarily for real-time monitoring of the tunneling process, allowing users to adjust equipment based on actual tunneling progress.

[0022] By implementing the above steps 100 to 103, users can independently select simulations according to their actual needs and flexibly adjust the twin scenarios according to the excavation progress.

[0023] In another exemplary embodiment of the present application, in order to form a more comprehensive database, in this embodiment, the process of constructing the model database in step 101 includes: Step 200: Obtain the tunneling equipment and its attribute data for the tunneling face. This attribute data includes basic attributes, technical parameters, geological compatibility, and economic and management attributes. Basic attributes include model, manufacturer, date of manufacture, and equipment status. Technical parameters include dimensions, weight, tunneling capacity, drive power, and propulsion force. Geological compatibility includes applicable strata, compressive strength range, and waterproof rating. Economic and management attributes include procurement cost, energy consumption, and maintenance cycle.

[0024] Furthermore, to meet the needs of all tunneling working faces, in this embodiment, the tunneling equipment covered by the tunneling working face may include: a production system and an auxiliary production system. The production system includes a combined miner and anchor machine, a roadheader, a belt conveyor, an anchor bolter, a self-propelled tail, a flexible belt conveyor, a continuous miner, a shuttle car, an anchor bolter, a feeder breaker, a crusher, and a shield machine. The auxiliary production system includes a power supply box, a local ventilator, and a belt conveyor.

[0025] Step 201: Construct a 3D model of the tunneling equipment according to a set scale. General modeling software is used to construct a 1:1, full-scale, high-precision 3D model of the tunneling equipment. The resulting 3D model's overall dimensional error is less than or equal to ±2%. Key components within the 3D model (such as the cutting drum, rake claws, and blade) must have an error of less than or equal to ±1%. Furthermore, during the 3D modeling process, detailed modeling techniques are required to avoid low-polygon simplification to meet the requirements of industrial design visualization, technical solution presentation, and simulation analysis. The resulting 3D model must achieve both mechanical structural accuracy, a high degree of appearance fidelity, and visual aesthetic appeal.

[0026] Step 202: Generate a label based on the attribute data of the tunneling equipment.

[0027] Step 203: Use labels to classify and store the constructed three-dimensional models to form a model database.

[0028] In another exemplary embodiment of the present application, in order to improve the accuracy of retrieval of the three-dimensional model, in step 101, the process of retrieving from the model database the three-dimensional model corresponding to the tunneling equipment in the trial operation configuration parameters or the tunneling operation configuration parameters includes: Step 300: Extract keywords from the attribute data of the tunneling equipment included in the trial operation configuration parameters or the tunneling operation configuration parameters. In the keyword extraction process, any unique attribute or any multiple attributes in the attribute data of the tunneling equipment can be used as keywords.

[0029] Step 301: Search for matching 3D models in a model database based on the extracted keywords. During the 3D model search, the matching degree between the keywords and the tags is determined.

[0030] Step 302: If multiple matching 3D models are found, the optimal 3D model is determined based on the matching degree or priority. The priority is determined based on the user's actual needs. For example, the user may set the lowest power consumption as the highest priority and the highest power consumption as the lowest priority.

[0031] Step 303: Use the optimal three-dimensional model as the three-dimensional model corresponding to the tunneling equipment in the trial operation configuration parameters or the tunneling operation configuration parameters.

[0032] In summary, the universal digital twin method for the excavation working face provided in this application facilitates users to construct a digital twin scene of the excavation working face according to actual needs, thereby realizing real-time adjustment and selection of excavation equipment and meeting the needs of remote real-time monitoring.
