DETAILED DESCRIPTION

[0018] The technical solution of a tunnel construction control system of the present invention belongs to an improved invention. On the basis of the existing technology, the present invention adds a ground dispatching center, which coordinates the construction information of various aspects such as construction resources, construction equipment and tunnel design models, coordinates the resource information of all parties with the goal of completing the construction task, and realizes the refined control of the construction process. The present invention solves the technical problem that the construction control system of the prior art lacks the ability to dispatch construction resources of all parties to complete the construction task at each construction stage.

[0019] Tunnel construction management and control system implementation example: The tunnel construction management and control system of this embodiment includes four modules: a perception module, a communication module, an information module and a decision module. Figure 1 As shown in the figure, the tunnel construction management and control system collects the overall data information of the tunnel through the perception module and transmits it to the main server through the communication module. The information module completes the analysis and calculation of the data. Finally, the project construction personnel manage and control the project through the decision-making module based on the analysis results of the information module.

[0020] like Figure 2 As shown in the figure, the perception module includes tunnel construction special equipment (i.e., various types of work trolleys) equipped with camera measurement systems, control sensors, laser radars and other perception components, and robots that integrate panoramic cameras, laser radars, survey radars, inertial navigation devices and other measurement devices. Among them, the special equipment mainly obtains the parameter information of its main components, and obtains the construction site data through optical measurement systems such as camera measurement systems. The robot obtains the three-dimensional information data of the tunnel through the simultaneous localization and mapping (SLAM) technology through various sensors such as panoramic cameras, laser radars, survey radars, etc., and completes the positioning of various construction equipment in the tunnel.

[0021] like Figure 3 As shown, the communication module includes 5G communication base stations, communication terminals, relay equipment, optical fiber communication systems and 5G core network. The communication module is used to realize communication between various devices in the entire project. Special equipment and robots in the tunnel are equipped with communication terminals to send and receive signals in real time. The communication of on-site equipment is processed by 5G communication base stations set up in corresponding areas of the tunnel, and all data communications are controlled by the 5G core network.

[0022] like Figure 4 As shown, the information module includes a tunnel three-dimensional model, a geological information model, a project information model, a simulation experiment model, an emergency decision-making model, a resource scheduling model and an equipment information model. The information module receives all on-site equipment and environmental information obtained by the communication module and integrates various big data models to process different types of information.

[0023] The processing algorithm built into the information module preliminarily processes the data scanned by the perception module to obtain a panoramic image of the tunnel surface, three-dimensional point cloud data, and geological information data. In order to achieve more realistic construction site information, the three-dimensional Gaussian Splatting (3DGS) algorithm is used to reconstruct the data and obtain a three-dimensional model of the tunnel. In addition, the tunnel geological information data (such as tunnel surrounding rock parameters, etc.) is processed to establish a geological information model for each area of ​​the tunnel. The three-dimensional tunnel model and the geological information model are then updated in real time based on the new round of data collected by the perception module.

[0024] In this embodiment, the tunnel 3D model and the geological information model serve as the basic database to support the completion of other parts. For example, the tunnel 3D model is used to measure various construction parameters (such as flatness, over-break and under-break, and tunnel clearance) in the tunnel construction area; when the equipment control center controls various construction equipment to perform construction tasks, the tunnel 3D model and the geological information model are used to obtain various information on the construction site in real time to facilitate and better complete the construction tasks.

[0025] In addition, the data center of the information module integrates all the information of the project to establish a project information model.

[0026] The information module can also simulate and model a specified area of ​​the tunnel to obtain a simulation experimental model to provide basic experimental data for subsequent simulation experiments.

[0027] Establish relatively practical solutions based on various emergency situations that may occur during the system construction process to form an emergency decision-making model.

[0028] The resource scheduling method is designed based on the overall project information and the 3D model of the tunnel design, and is managed uniformly by the resource scheduling model.

[0029] Each device is modeled based on the device information obtained by the perception module sensor, and the device information model automatically analyzes the real-time status of each device to support resource scheduling.

[0030] All data in the information module are updated in time with the data in the perception module. In addition, this module integrates multiple machine learning models to achieve intelligent collaboration of each model through Agents to help project personnel complete the intelligent processing of various data and assist the decision-making module to complete its work better.

[0031] For example, various types of work trolley control models are built through machine learning models to guide work trolley operators to control the work trolleys to complete construction tasks.

[0032] like Figure 5 As shown in the figure, the decision-making module includes ground dispatch center, data analysis center, project management center, emergency decision-making center, equipment control center and system maintenance center. Project personnel can realize the overall control of project construction through the decision-making module.

[0033] The ground dispatch center obtains the construction resource information in the resource dispatch model of the information module in real time, including the equipment parameter information of special equipment and robots, the status and quantity information of each construction resource, and its corresponding location information, etc. The ground dispatch center cooperates with other control centers to complete the resource dispatch work of various operations.

[0034] The data analysis center obtains the simulation experiment model in the information module and performs analysis and processing to assist in completing tasks such as simulation experiments and provide data support for other management and control centers.

[0035] The project management center plans the overall construction work of the project and controls the construction progress.

[0036] The emergency decision center can respond to various emergencies that occur in the project in a timely manner by calling the emergency decision model.

[0037] The equipment control center provides a remote driving platform, through which equipment operators can remotely control construction site equipment and complete various work tasks assigned by the project management center.

[0038] The System Maintenance Center provides maintenance for the entire management and control system, including troubleshooting of management and control system failures and updating of various operating parameters of the management and control system (including updating the model parameters of each machine learning model based on the latest construction operation data).

[0039] In addition, the decision-making module integrates speech recognition and a large language model (LLM). When making decisions, artificial intelligence (AI) can be asked to provide various project information or generate solutions. Various operations can be completed through input devices such as voice or keyboard.

[0040] As mentioned above, the perception module is composed of a work trolley equipped with various types of sensors and a measuring robot. The measuring robot collects and scans data such as the tunnel contour, and spatially locates the work trolley at the construction location. The face of the working area and the surrounding rock surface nearby are measured by the scanning device on the work trolley to obtain characteristic data. The communication module includes communication facilities such as 5G base stations arranged in the tunnel. The data information obtained by the perception module is sent to the information module in a timely manner through the communication module. The information module analyzes and processes the collected data to obtain data such as the tunnel three-dimensional model, geological information, project progress, and equipment information. The decision-making module will then present the analysis results to the staff, and the staff will call the decision-making module to manage and control the operating equipment based on the project situation and needs.

[0041] like Figure 6 As shown, during tunnel construction, personnel in different positions of the project arrive at the ground control center corresponding to the decision-making module to work. The project management center calls the project information model to obtain data, and visualizes it through a display or VR glasses, such as the rendered three-dimensional tunnel model, the status and availability of various equipment and resources, so as to judge the project construction status, and then create and dispatch construction tasks according to the construction plan, or directly choose to dispatch construction tasks intelligently recommended by the information module's machine learning model.

[0042] Subsequently, the ground dispatch center dispatches various resources according to the tasks assigned by the project management center, supplements the resource information of the tasks, and then dispatches the tasks to the equipment control center according to the process. The equipment operator operates the equipment console to control the task-specified equipment and resources to complete the assigned tasks. The information module automatically records the complete operation data, and the data analysis center selects the better construction operation data and sends it to the system maintenance center, and the system maintenance center personnel use the new data to train and maintain the machine learning model.

[0043] For some special work tasks, the project management center can assign them to the data analysis center, and the data analysis center personnel will set up simulation data for simulation experiments, and then feed back the experimental results to the project management center.

[0044] Specifically, special tasks include tasks that require simulation experiments. For example, if a certain operation vehicle needs to be loaded with a new operation module, simulation tests are conducted in advance through the data center. Or for certain difficult construction sections, simulation experiments are conducted through the data analysis center to confirm the optimal construction plan.

[0045] The system can gradually evolve by collecting project data and optimizing training, which is mainly divided into three stages.

[0046] Phase 1: In the initial stage of application of the intelligent management and control system, since the system has been initially put into use, the amount of data accumulated in the database is small, and the machine learning model of the information module does not have sufficient data for training. At this stage, the management and control system mainly relies on manual calls to pre-arranged plans or project personnel customize plans based on actual conditions. The model prompt function can provide preliminary modification plans.

[0047] Phase 2: When sufficient project construction data is collected, the models of the information module can collaborate with each other through the Agents framework to automatically generate and process most of the work tasks, and the collected data of the completed on-site work results are processed and compared with the tunnel design model, and then the completed work is scored in multiple indicator dimensions. After automatically optimizing the parameters, the simulation analysis is completed in combination with the simulation experiment model. The control parameters are optimized multiple times according to the simulation result data to find the optimal solution, and the closed-loop optimization of the construction work control parameters is achieved. For most work tasks, project personnel only need to check the rationality and make appropriate modifications to complete the decision. Personnel in the equipment control center can interact with AI to let it automatically perform tasks. The operator supervises AI through the equipment to complete the work and corrects it in time when AI makes an error.

[0048] The third stage: After long-term use, the control system accumulates a large amount of data, and the intelligent model of the system is optimized and trained to achieve complete intelligent functions. In this stage, the project decision maker only needs to provide the design tunnel information, and the intelligent system can independently create tasks and dispatch resources to complete the work. The project team only needs a small number of people to complete the necessary supervision and maintenance work.

[0049] The present invention has the following characteristics: The present invention proposes a tunnel intelligent construction management and control system to realize the intelligent management and control of tunnel construction project information and various equipment and resources, which can significantly improve the overall project management efficiency, reduce the labor intensity of relevant personnel, ensure the personal safety of construction personnel, and provide great convenience for project management and task decision-making.
