[0002] During the construction and maintenance of large underground powerhouse caverns, the collection of geological information plays a crucial role in the analysis and judgment of surrounding rock stability. These geological information not only provides basic data for engineering design, but also serves as an important basis for construction safety and subsequent maintenance decisions. However, due to the particularity of the underground powerhouse cavern environment, such as high dust, insufficient lighting, and potential safety risks, it poses many challenges to the acquisition of on-site geological information.

[0003] Currently, for the collection of geological information of large underground powerhouse caverns, it mainly relies on the following methods: traditional manual cataloging, three-dimensional laser scanning technology, unmanned aerial vehicle (UAV) photography technology, and manual cataloging after the modeling of cavern point cloud data. Although these methods can meet the requirements of geological information collection to a certain extent, they each have obvious limitations.

[0004] The traditional manual cataloging method, although widely used, has problems of process fragmentation due to its dependence on secondary digital processing after on-site recording. It is not only time-consuming and laborious, with low drawing efficiency, but also extremely vulnerable to the subjective factors of cataloging personnel, resulting in frequent problems such as non-standard recording content, information missing or omission. For three-dimensional laser scanning technology and UAV photography technology, although they can improve the efficiency and objectivity of data collection, in the complex and changeable construction environment of underground cavern groups, due to factors such as intersecting working faces, insufficient lighting, high dust, and limited space for setting up instrument equipment, it is often difficult to obtain clear and accurate image data, thus seriously affecting the interpretation results of geological information. Summary of the Invention

[0037] Figure 1 It is a flowchart of the method for cataloging geological information of underground powerhouse caverns in an embodiment of the present invention. Detailed Embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] The purpose of this embodiment is to provide a geological information cataloging system for underground powerhouse 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 powerhouse caverns according to the parameter information of the underground powerhouse caverns 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 further used to catalog the geological information of the obtained underground powerhouse caverns 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 update.

[0040] Specifically, the present invention uses professional modeling software and applies prefabricated 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, in this embodiment, is specifically manifested as an easily accessible web-based platform. On the platform, the three-dimensional model is stored in the cloud server for access and update at any time.

[0041] It should be noted that the three-dimensional model in this embodiment adopts a continuous data format, which can accurately express the spatial structure and geometric features of the underground powerhouse cavern. The geological information, on the other hand, exists in the form of discrete format information, which includes the specific locations and attributes of key geological features such as fissures, faults, and lithology. The combination of these two data formats enables the collection and cataloging of geological information to be carried out more efficiently and accurately. This not only improves the efficiency and accuracy of geological information collection but also realizes real-time data sharing and collaborative editing through the cloud collaboration module.

[0042] In this embodiment, the modeling module 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 powerhouse cavern; the model cutting unit is used to convert the three-dimensional model into an engineering plan view or divide it into engineering sub-plan views according to preset rules.

[0043] The engineering sub-plan views in this embodiment include the plan views of the outer end wall, inner end wall, floor, roof arch, right side wall, and left side wall of the underground powerhouse cavern.

[0044] In this embodiment, the collection 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 synchronously transmit the cataloged geological information back to the cloud collaboration module; the dual-mode cataloging unit converts the three-dimensional model into an unfolded drawing cataloging mode and a part-by-part cataloging mode according to the engineering plan view and the engineering sub-plan views; the input unit is used to input the obtained geological information into the corresponding positions in the three-dimensional model through the unfolded drawing cataloging mode and / or the part-by-part 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 terminal or a PC terminal. Users can log in to the cataloging software and use the model loading unit provided in the cataloging software to download the 3D model of the underground powerhouse cavern from the cloud server. The model loading unit is also used to synchronously transmit the cataloged geological information back to the server. The cataloging software is provided with a dual-mode cataloging unit, which converts the 3D model into an unfolded drawing cataloging mode and a part-by-part cataloging mode according to the engineering plan drawing and the engineering division plan drawing. The cataloging personnel carry the mobile terminal to collect and obtain on-site geological information, and different cataloging methods can be selected according to the project situation.

[0046] In the unfolded drawing cataloging mode, the cataloging personnel can conduct geological cataloging of the whole underground powerhouse cavern from a global perspective, so as to obtain comprehensive geological information. In the part-by-part cataloging mode, the 3D model of the underground powerhouse cavern is automatically divided into blocks, specifically including the outer end wall, inner end wall, floor, crown, right side wall, left side wall, etc. The cataloging personnel can conduct detailed geological cataloging for each part. These two cataloging modes can be used alternately, and the cataloging personnel can flexibly switch according to the actual situation on site to ensure the accuracy and integrity of geological information collection.

[0047] Specifically, to facilitate viewing the cataloging situation and progress of the underground powerhouse cavern and optimize the user interface and functions of the cataloging software, when conducting geological cataloging of the underground powerhouse cavern, the cataloging software also supports switching the 2D cataloging interface in the unfolded drawing cataloging mode and the part-by-part cataloging mode to a 3D view at any time, and viewing the current cataloging situation through rotation, zooming in, zooming out, and dragging functions in the 3D perspective. It should be noted that when switching, the cataloging software automatically synchronizes the current cataloging data progress to ensure that the data in the 3D view is real-time consistent with that in the 2D cataloging interface, so as to meet the viewing requirements of the cataloging personnel for the global progress and details.

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

[0049] In this embodiment, the acquisition module further includes a picture embedding unit connected to the model loading unit; the picture embedding unit is used to embed the obtained on-site picture information into the corresponding position in the 3D 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 cataloging personnel use a mobile terminal for geological information cataloging, the picture embedding unit can receive on-site pictures taken by the mobile terminal (such as a mobile phone or a PC), and associate these pictures with information such as the geographical location and geological description of the cataloging point. Subsequently, the picture embedding unit synchronizes the 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 3D model.

[0051] In addition, the picture embedding unit also annotates and manages the embedded pictures, such as adding picture descriptions, shooting times, shooting accounts, etc., for subsequent data query and analysis. In this way, the geological information cataloging system for underground powerhouse caverns can record and analyze geological information more comprehensively, improving 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 3D model to the acquisition module, and is also used to update the 3D model according to the 3D 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 structurally store the on-site picture information and geological information of each cataloging point.

[0053] Specifically, the cloud collaboration module also includes a data synchronization unit, which is used to update the 3D model according to the 3D model containing geological information synchronously transmitted 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 picture information with the geological information, and also uses database technology to structurally store this information in the cloud database of the cloud server. A complete, accurate and intuitive geological information database is constructed for subsequent data retrieval and analysis.

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

[0055] Specifically, the geological information in this embodiment includes key elements such as stratigraphic information, fracture information, joint information, weathering and unloading information, groundwater information, sampling information, and deformation and failure information. Each piece of information has its specific input template and format requirements to ensure data unity and comparability. Therefore, a set of structured, standardized, and normalized data input formats are constructed in the cataloging software in this 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 input formats in the cataloging software to input the collected geological information one by one.

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

[0057] Stratum information includes the name of rock and soil, the type name of rock and soil, stratum code, geological age, geological origin, humidity, dip direction of the bedding plane, and dip angle of the bedding plane;

[0058] Fault information includes the global number, local number, fault type, fault type, maximum width of the structural plane, minimum width of the structural plane, dip direction, dip angle, state of the structural plane, filling type, filling material, description of typical features, end distance, and groundwater conditions;

[0059] Joint information includes joint number, dip direction, dip angle, joint type, joint spacing, number of fissures (pieces), joint state, groundwater conditions, JRC (joint roughness coefficient), and degree of cohesion;

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

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

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

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

[0064] In this embodiment, the acquisition module further 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 multiple catalogings at the same coordinate; it also constructs a data traceability chain through the input time and input account information to support the full life cycle traceability of the cataloging process.

[0065] Specifically, in this embodiment, when the detection unit detects multiple catalog records at the same coordinate position in the system, it automatically triggers the version comparison mechanism. This mechanism can intelligently analyze the catalog data of different versions, identify the differences and changes between the data, and generate a detailed revision log accordingly. 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 traceability of the data. In addition, the detection unit uses the input time and input account information to construct a clear data traceability chain. This chain can trace the source, modification history, and relevant responsible persons of each catalog data, thus realizing the full life cycle management of the catalog process. This not only improves the transparency and traceability of data management, but also provides strong guarantee for data quality control and accountability. The detection unit also includes synchronously transmitting back the detected content, including the version comparison result, the revision log, and any abnormal or conflict information, 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 stores the received information to ensure that the 3D model and the geological information database in the cloud can timely reflect the latest catalog results and data revisions.

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

[0067] Step 1: Construct a 3D model based on the underground powerhouse caverns, convert the 3D model into an engineering plan view, and divide it into engineering sub-plan views according to preset rules;

[0068] Step 2: Load the 3D model through a mobile terminal, select the key feature points of the structural plane on the 3D model based on the unfolded drawing cataloging mode and / or the part-by-part cataloging mode, generate the geometric contour of the structural plane according to the key feature points, and associate and input the obtained geological information with the model space coordinates;

[0069] Step 3: Real-time synchronously update the 3D model containing geological information, associate and embed the on-site picture information of each catalog point, and structurally store the information of each catalog point to obtain a 3D model containing geological information.

[0070] In this embodiment, associating and inputting the obtained geological information with the model space coordinates specifically includes:

[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.
