[0037] Figure 1 It is a flow chart of the method for cataloging geological information of underground powerhouse caverns in an embodiment of the present invention. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The purpose of this embodiment is to provide a geological information cataloging system for underground power plant caverns, including: a modeling module, a collection module and a cloud collaboration module; the modeling module is used to construct a three-dimensional model of the underground power plant cavern according to the parameter information of the underground power plant cavern, and transmit the three-dimensional model to the cloud collaboration module; the collection module is communicatively connected to the cloud collaboration module, and is used to receive and load the three-dimensional model from the cloud collaboration module; the collection module is also used to catalog the acquired geological information of the underground power plant cavern into the loaded three-dimensional model, and synchronously transmit the three-dimensional model containing the geological information back to the cloud collaboration module for storage and updating.

[0040] Specifically, the present invention uses professional modeling software and assembly modeling technology to create a three-dimensional model of the underground powerhouse cavern based on the detailed parameter information of the underground powerhouse cavern. This three-dimensional model is used as the basic framework for subsequent geological information collection and cataloging. Subsequently, the three-dimensional model is transmitted to the cloud collaboration module, which is specifically manifested as an easily accessible web platform in this embodiment. On the platform, the three-dimensional model is stored in the cloud server for access and update at any time.

[0041] It is worth noting that the three-dimensional model in this embodiment uses a continuous data format, which can accurately express the spatial structure and geometric characteristics of the underground powerhouse cavern. Geological information exists in the form of discrete format information, which contains the specific location and attributes of key geological features such as cracks, faults, and lithology. The combination of these two data formats enables the collection and cataloging of geological information to be more efficient and accurate. This not only improves the efficiency and accuracy of geological information collection, but also realizes real-time sharing and collaborative editing of data through the cloud collaboration module.

[0042] The modeling module in this embodiment includes a modeling unit and a model cutting unit; the modeling unit is used to construct a three-dimensional model with an engineering coordinate system based on the axis parameters of the underground plant cavern; the model cutting unit is used to convert the three-dimensional model into an engineering plan or divide it into engineering section plans according to preset rules.

[0043] The engineering section plan described in this embodiment includes the plan views of the outer end wall, inner end wall, bottom plate, top arch, right wall and left wall of the underground powerhouse cavern.

[0044] In this embodiment, the acquisition module includes a model loading unit, a dual-mode cataloging unit and an input unit; the model loading unit is used to load the three-dimensional model through the cloud collaboration module, and is also used to synchronize the cataloged geological information back to the cloud collaboration module; the dual-mode cataloging unit converts the three-dimensional model into an expanded view cataloging mode and a sub-section cataloging mode according to the project plan and the project section plan; the input unit is used to enter the acquired geological information into the corresponding position in the three-dimensional model through the expanded view cataloging mode and / or the sub-section cataloging mode.

[0045] Specifically, in this embodiment, the acquisition module is specifically a cataloging software, which is installed on a mobile terminal, including a mobile phone or a PC. The user logs in to the cataloging software and uses the model loading unit built into the cataloging software to download the three-dimensional model of the underground powerhouse cavern from the cloud server. The model loading unit is also used to synchronize the cataloged geological information back to the server; the cataloging software is provided with a dual-mode cataloging unit, which converts the three-dimensional model into an expanded view cataloging mode and a sub-division cataloging mode according to the engineering plan and the engineering sub-division plan. The cataloging personnel carry mobile terminals to collect and obtain on-site geological information, and the cataloging personnel can choose different cataloging methods according to the project situation.

[0046] In the expanded diagram cataloging mode, the cataloging staff can catalog the underground powerhouse cavern as a whole from a global perspective, thereby obtaining comprehensive geological information. In the part-by-part cataloging mode, the 3D model of the underground powerhouse cavern is automatically divided into blocks, specifically into the outer end wall, inner end wall, bottom plate, top arch, right wall and left wall. The cataloging staff can conduct detailed geological cataloging for each part. These two cataloging modes can be used interchangeably, and the cataloging staff can flexibly switch according to the actual situation on site to ensure the accuracy and completeness of geological information collection.

[0047] Specifically, in order to facilitate the viewing of underground powerhouse cavern cataloging status and progress, and to optimize the user interface and functions of the cataloging software, when conducting geological cataloging of underground powerhouse caverns, the cataloging software also supports switching the 2D cataloging interface in the expanded view cataloging mode and the sub-part cataloging mode to the 3D view at any time, and viewing the current cataloging status through rotation, zooming in, zooming out and dragging in the 3D perspective. It should be noted that when switching, the cataloging software automatically synchronizes the data progress of the current cataloging to ensure that the data of the 3D view and the 2D cataloging interface are consistent in real time, so as to meet the cataloging personnel's viewing needs for the overall progress and details.

[0048] In addition, the input unit also marks and manages the input geological information, such as adding geological information description, input time, input account and other information, to facilitate subsequent data query and analysis.

[0049] In this embodiment, the acquisition module also includes a picture embedding unit connected to the model loading unit; the picture embedding unit is used to embed the acquired on-site picture information into the corresponding position in the three-dimensional model at each cataloging point; the picture embedding unit is used to synchronously transmit the on-site picture information back to the cloud collaboration module through the model loading unit.

[0050] Specifically, when the cataloger uses a mobile terminal to catalog geological information, the picture embedding unit can receive on-site pictures taken by a mobile terminal (such as a mobile phone or PC) and associate these pictures with the geographical location, geological description and other information of the cataloging point. Subsequently, the picture embedding unit synchronizes these associated picture information with the cloud collaboration module through the model loading unit to ensure that the pictures can be accurately embedded in the corresponding cataloging point position in the three-dimensional model.

[0051] In addition, the image embedding unit also annotates and manages the embedded images, such as adding image descriptions, shooting time, shooting account and other information, to facilitate subsequent data query and analysis. In this way, the underground powerhouse cavern geological information cataloging system can more comprehensively record and analyze geological information and improve the accuracy and efficiency of geological exploration.

[0052] The cloud collaboration module includes a data synchronization unit and a management unit; the data synchronization unit is connected to the acquisition module, and is used to transmit the three-dimensional model to the acquisition module, and is also used to update the three-dimensional model according to the three-dimensional model containing the geological information synchronously transmitted back by the acquisition module; the management unit is used to embed on-site picture information at each cataloging point, and to structure the storage of on-site picture information and geological information at each cataloging point.

[0053] Specifically, the cloud collaboration module also includes a data synchronization unit, which is used to update the three-dimensional model based on the three-dimensional model containing geological information synchronized back by the cataloging software to ensure the accuracy and timeliness of the model. In addition, for each cataloging point, the management unit accurately associates the on-site image information with the geological information, and also uses database technology to store this information in a structured manner in the cloud database of the cloud server. Constructing a complete, accurate and intuitive geological information database facilitates subsequent data retrieval and analysis.

[0054] The geological information in this embodiment includes: stratum information, fracture information, joint information, weathering unloading information, groundwater information, sampling information and deformation and damage information in the underground powerhouse cavern.

[0055] Specifically, the geological information in the present embodiment includes key elements such as stratigraphic information, fracture information, joint information, weathering unloading information, groundwater information, sampling information, and deformation and damage information. Each piece of information has its specific input template and format requirements to ensure the uniformity and comparability of data. Therefore, a set of structured, standardized, and normalized data entry formats are constructed in the cataloging software in the present embodiment to ensure that various types of geological information in the underground powerhouse cavern can be comprehensively and accurately collected during the geological cataloging process. During the geological cataloging process, the cataloging personnel will use these standardized data entry formats in the cataloging software to enter the collected geological information one by one.

[0056] The following are the specific contents of various types of geological information collected during the geological information cataloging process:

[0057] Stratigraphic information includes rock and soil name, rock and soil class name, stratigraphic code, geological age, geological origin, humidity, layer dip, and layer inclination;

[0058] Fault information includes global number, local number, fault type, fault type, maximum width of structural surface, minimum width of structural surface, dip, inclination, structural surface status, filling type, filling material, typical feature description, end distance, and groundwater conditions;

[0059] Joint information includes joint number, dip, inclination, joint type, joint spacing, number of cracks, joint state, groundwater conditions, JRC (joint roughness coefficient), and cohesion;

[0060] Weathering unloading information includes weathering degree and unloading degree;

[0061] Groundwater information includes groundwater type, flow rate (ml / s), flow velocity (cm / s), water pressure (m water column), structural conditions, and description;

[0062] Sampling information includes sampling number, sampling type, sampler, sampling date, stratum code, rock and soil name;

[0063] Deformation damage information includes damage type, damage location, area (m²), maximum depth (m), and description.

[0064] The acquisition module in this embodiment also includes a detection unit; the detection unit is connected to the input unit, and is used to automatically establish a version comparison relationship and generate a revision log when it detects that the same coordinates have been cataloged multiple times; it also builds a data traceability chain through the entry time and entry account information to support the full life cycle traceability of the cataloging process.

[0065] Specifically, in this embodiment, the detection unit automatically triggers the version comparison mechanism when the system detects that there are multiple catalog records at the same coordinate position. This mechanism can intelligently analyze different versions of catalog data, identify the differences and changes between the data, and generate a detailed revision log based on this. The revision log not only records the specific content of the data modification, but also retains the complete data before and after the modification, providing strong support for the historical tracing of the data. In addition, the detection unit also uses the entry time and entry account information to build a clear data traceability chain. This chain can trace the source, modification history and relevant responsible persons of each catalog data, thereby realizing the full life cycle management of the catalog process. This not only improves the transparency and traceability of data management, but also provides a strong guarantee for data quality control and accountability. The detection unit also includes synchronizing the detected content, including version comparison results, revision logs, and any abnormal or conflicting information, back to the data synchronization unit in the cloud collaboration module through the model loading unit. After receiving this information, the data synchronization unit will immediately update it. In addition, the management unit in the cloud collaboration module will store the received information to ensure that the three-dimensional model and geological information database in the cloud can promptly reflect the latest cataloging results and data revisions.

[0066] like Figure 1 As shown, a method for cataloging geological information of underground powerhouse caverns includes the following steps:

[0067] Step 1: construct a three-dimensional model based on the underground powerhouse cavern, convert the three-dimensional model into an engineering plan and divide it into engineering sub-plans according to preset rules;

[0068] Step 2: Load the three-dimensional model through a mobile terminal, select key feature points of the structural surface on the three-dimensional model based on the expanded view cataloging mode and / or the sub-part cataloging mode, generate the geometric contour of the structural surface according to the key feature points, and associate the obtained geological information with the model space coordinates and enter them;

[0069] Step 3: Real-time synchronous update of the three-dimensional model containing geological information, associated and embedded on-site picture information of each cataloging point, and structured storage of the information of each cataloging point to obtain a three-dimensional model containing geological information.

[0070] In this embodiment, the acquired geological information is associated with the model space coordinates and entered, specifically including:

[0071] In the expanded diagram cataloging mode, different geological information is entered into the corresponding cataloging points using the corresponding input formats based on the plane coordinate system of the engineering plan; in the sub-part cataloging mode, different geological information is entered into the corresponding cataloging points using the corresponding input formats by selecting the preset engineering sub-part plan. Specifically, the preset engineering distribution plan refers to the corresponding engineering sub-part plan selected by the data entry personnel when cataloging different parts of the underground powerhouse.

[0072] Specifically, before entering data, it also includes selecting the expanded view cataloging mode and / or the part-by-part cataloging mode, selecting the key feature points of the structural surface on the three-dimensional model by manual touch or stylus, and generating the geometric contour of the structural surface based on the key feature points, that is, outlining the structural surface contour on the three-dimensional model by manual point tracing, and then further entering the geological information obtained from field observations and analysis.

[0073] The present invention combines the capabilities of remote collaboration and direct on-site cataloging, optimizing the process of geological information recording. Specifically, through the close cooperation between the cloud collaboration module and the acquisition module, the system enables on-site cataloging personnel to remotely and instantly receive the three-dimensional model generated by the modeling module, and directly catalog the geological information on the loaded three-dimensional model. This process is not only intuitive and efficient, but also greatly reduces the need for secondary digital entry after manual collection in traditional methods.

[0074] Furthermore, the on-site cataloguing personnel of the present invention can accurately record geological information on the three-dimensional model by simply outlining and tracing points. This direct and instant data recording method not only ensures the original accuracy and integrity of the data, but also avoids the errors and inconveniences that may be introduced by multiple transcriptions and digitizations in traditional methods.

[0075] In addition, the existence of the cloud collaboration module enables remote experts and on-site cataloging personnel to share and discuss cataloging data in real time, further improving the quality and reliability of the data. This combination of remote collaboration and direct on-site cataloging not only optimizes the workflow, but also significantly improves overall work efficiency, opening up a new path for the recording and analysis of underground powerhouse cavern geological information.

[0076] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
