[0016] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0020] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Before and during construction, when detecting the location of underground fiber optic cables, electrical cables, and gas pipelines, the relevant technology typically relies on a combination of drawings and manual experience. However, this method suffers from extremely low positioning accuracy (errors reaching the meter level), delayed response (requiring manual confirmation by pausing construction machinery), and limited coverage. This not only makes construction machinery prone to accidents due to positioning errors or operational negligence, but also makes construction workers susceptible to misoperation in complex underground environments due to obstructed vision or lack of information. This leads to significant pressure on construction safety management and increases the risk of electric shock or mechanical injuries to construction workers, directly threatening their safety. Therefore, to avoid incorrect instructions given to construction workers due to human error, it is crucial to conduct technical briefings and confirmations regarding underground facilities before construction begins.

[0022] Based on this, this application provides a solution that uses high-precision positioning technology to obtain current geographical location information, and then uses the current underground pipeline information and the current geographical location information to update the underground pipeline 3D map. This can improve the display accuracy of the underground pipeline 3D map, reduce the deviation between the displayed pipeline model and the actual pipeline, avoid displaying incorrect underground pipeline 3D maps, thereby reducing the probability of construction errors or construction accidents, and reducing the difficulty of pipeline operation and maintenance management.

[0023] This application provides a construction method for a server, wherein the server and a construction terminal are connected in communication, as described above. Figure 1 , Figure 1 This paper illustrates a flowchart of a construction method provided in an embodiment of this application. The construction method includes steps S10 to S30: Step S10: Receive the current underground pipeline information and current geographical location information of the construction area uploaded by the construction terminal; wherein, the construction area is equipped with a real-time dynamic positioning network, and the current geographical location information is collected by the real-time dynamic positioning mobile station in the real-time dynamic positioning network and then uploaded to the construction terminal.

[0024] It should be noted that the execution entity in this embodiment is the server.

[0025] Real-time kinematic (RTK) networks refer to the deployment of RTK base stations within the construction area. Before construction, RTK mobile stations transmit differential correction data to the server in real time via 4G / 5G networks through construction terminals to ensure the coverage of the RTK network.

[0026] An RTK rover can be a positioning data acquisition device that integrates a Global Navigation Satellite System (GNSS) receiver and an Inertial Measurement Unit (IMU). Due to the fusion of RTK and IMU, the RTK rover can achieve high-precision real-time positioning by dynamically compensating for positioning drift in obstructed environments. This can significantly reduce the risk of misoperation caused by positioning errors, making the construction method provided in this embodiment particularly suitable for earthwork construction in densely paved areas such as subway tunnels and municipal roads. Specifically, high precision refers to a fixed error of ±2 cm for the detection accuracy of underground facilities.

[0027] In actual operation, the construction personnel use a handheld RTK mobile station on the ground at the construction site. The RTK mobile station uses real-time dynamic differential positioning technology to obtain the current geographical location information in real time. The current geographical location information provides a coordinate reference for updating the three-dimensional map of underground pipelines. Specifically, the current geographical location information can be the current location's latitude and longitude (lat, lon), elevation (alt), and orientation angle, etc.

[0028] The current underground pipeline information can be entered by construction personnel in the construction terminal. In one feasible implementation, the current underground pipeline information includes the construction location, excavation width and depth, excavation time, current underground pipeline type, and construction unit information.

[0029] Step S20: Update the 3D map of underground pipelines based on the current underground pipeline information and the current geographical location information.

[0030] In one feasible implementation, the three-dimensional map of underground pipelines is updated based on the current underground pipeline information and the current geographical location information, including steps S21-S22: Step S21: Generate a pipeline excavation model based on the current underground pipeline information and the prefabricated pipeline model.

[0031] It should be noted that the prefabricated pipeline model can be any type of pipeline model pre-made by the server.

[0032] Specifically, since the current underground pipeline information includes the construction location, excavation width and depth, excavation time, current underground pipeline type, and construction unit information, the server calls the prefabricated pipeline model and generates a pipeline excavation model with the current underground pipeline information, including the construction location, excavation width and depth, and construction unit information, based on the current underground pipeline information.

[0033] Step S22: Based on the current geographical location information, integrate the pipeline excavation model into the underground pipeline 3D map to update the underground pipeline 3D map.

[0034] A 3D map of underground pipelines can be a 3D map generated by a server based on underground pipeline drawings of the construction area. This 3D map of underground pipelines (i.e., virtual underground pipelines) reflects the condition of underground pipelines before construction.

[0035] Specifically, the current geographic location information (i.e., real-world spatial data) is used to define the boundaries of the pipeline excavation model. Based on the current geographic location information, the pipeline excavation model can be placed into the 3D map of underground pipelines, forming a 3D map of underground pipelines with coordinates and current pipeline burial information. By overlaying the virtual underground pipelines with real-world spatial data, a WYSIWYG real-time pipeline display is generated, showing a digital twin model identical to the actual construction scenario. When supervising and guiding non-electrical construction, it is no longer necessary for professional personnel to follow and check cable drawings on-site, improving work efficiency and ensuring work safety.

[0036] In one feasible implementation, after step S22, the construction method further includes: Step B23: Create an electronic fence model that covers the pipeline excavation model in the updated 3D map of underground pipelines. Step B24: In the updated 3D map of underground pipelines, mark the area within the electronic fence model as a restricted area.

[0037] In this embodiment, by forming an electronic fence model in the updated 3D map of underground pipelines and marking the area within the electronic fence model as a restricted area, a protective closed loop is actively formed, which can effectively reduce the probability of underground pipeline digging accidents and avoid the risk of electric shock or mechanical injury to construction workers.

[0038] Specifically, in the updated 3D map of underground pipelines, corresponding closed electronic fences are generated outside multiple pipeline excavation models. These multiple closed electronic fences form an electronic fence model that surrounds the pipeline excavation models. The area within this electronic fence model is a restricted zone. In one feasible implementation, the distance between the pipeline excavation model and the corresponding closed electronic fence is a first preset width D1, where D1 satisfies: 0m < D1 ≤ 1m. In one example, the first preset width is 1m.

[0039] In this embodiment, the area within the electronic fence model, namely the area where the pipeline excavation model is located and the area between the pipeline excavation model and the closed electronic fence, are all marked as restricted areas. The marking method can be a combination of display color change, text marking and icon marking, and no specific restrictions are made here.

[0040] For construction safety considerations, in one feasible implementation, after marking the area within the electronic fence model as a restricted area in the updated 3D map of underground pipelines, the construction method further includes: generating a safety buffer zone covering the electronic fence model in the updated 3D map of underground pipelines.

[0041] In this embodiment, a larger safety buffer zone is generated outside the restricted area to allow construction workers to react promptly. Specifically, a closed safety buffer zone is formed in the updated 3D map of underground pipelines at a second preset width from the electronic fence model to prevent construction workers from directly entering the restricted area. The second preset width can be set based on the first preset width. In one embodiment, when the first preset width is D1, and D1 satisfies: 0m < D1 ≤ 1m, the second preset width is D2, and D2 satisfies: 9m ≤ D1 < 10m. In one example, when the first preset width is 1m, the second preset width can be 9m.

[0042] In addition, when construction workers reach the safety buffer zone, the server sends a pipeline exposure warning to the construction terminal so that the workers can check it and thus provide an early warning. The form of the pipeline exposure warning is not specifically limited here.

[0043] Step S30: Send the updated 3D map of underground pipelines to the construction terminal so that the construction terminal can display the updated 3D map of underground pipelines. The updated 3D map of underground pipelines is used as a reference for production scheduling of underground pipeline construction.

[0044] Understandably, updating the 3D map of underground pipelines based on current buried pipeline information and geographical location data enables a WYSIWYG (What You See Is What You Get) real-time display of the pipelines. During non-power construction, it eliminates the need for professional personnel to accompany workers and review cable drawings on-site, improving work efficiency and ensuring operational safety. Furthermore, the current geographical location information is collected using high-precision positioning technology. When the server uses this information to update the 3D map of underground pipelines, it can improve the display accuracy, reduce deviations between the displayed pipelines and the actual pipelines, and avoid displaying incorrect 3D maps. This provides accurate reference for the production scheduling of buried pipeline construction, effectively solving the technical problems of extremely low positioning accuracy, slow response, and limited coverage in methods of detecting underground pipeline locations during excavation work.

[0045] Production scheduling refers to the scheduling of work progress or any construction equipment during construction. For example, production scheduling refers to truck scheduling. Specifically, by referring to the updated 3D map of underground pipelines, the server can send production scheduling alarms to the intelligent truck scheduling system in advance to prevent trucks from entering the construction area.

[0046] In one feasible implementation, after integrating the pipeline excavation model into the underground pipeline 3D map based on the current geographical location information to update the underground pipeline 3D map, the construction method further includes: displaying the updated underground pipeline 3D map.

[0047] Specifically, the server includes a management backend module and a digital twin module. After the digital twin module updates the 3D map of underground pipelines, it sends the updated 3D map to the management backend module. Since the management backend module includes a command center screen, the updated 3D map of underground pipelines is displayed in real time on the command center screen. The updated 3D map of underground pipelines includes current underground pipeline burial information, allowing technicians to understand the remote construction status in real time from indoors, including construction location and construction unit information, as well as other current underground pipeline burial information.

[0048] In one feasible implementation, after updating the three-dimensional map of underground pipelines based on the current underground pipeline information and the current geographical location information, the construction method further includes: in the event of an accident during the construction of the current pipeline, generating a construction playback video based on historical underground pipeline information.

[0049] Specifically, historical underground pipeline information can be all current underground pipeline information stored before the time of the accident, and based on this information, historical construction trajectory videos can be generated through model building, animation rendering, and other processing.

[0050] In this embodiment, in the event of an accident during the construction of the current pipeline, the responsibility can be quickly located by replaying the trajectory video of the construction location (i.e., construction playback video), thereby shortening the downtime for investigation and repair, specifically by 60% or more.

[0051] Furthermore, to achieve the above objectives, this application also proposes a construction method for a construction terminal, wherein the construction terminal is communicatively connected to a server, and the construction method includes steps A10 to A30: Step A10: According to the construction instructions, send the current geographical location information of the construction area and the current underground pipeline information to the server.

[0052] It should be noted that a construction instruction can be issued by construction personnel based on the current geographical location information of the construction area, indicating that the area is suitable for underground pipeline construction. If the construction personnel do not issue a construction instruction, it means that underground pipelines (such as fiber optic cables, electrical cables, and gas pipelines) exist in the construction area, making construction impossible, and the process ends.

[0053] It should also be noted that the execution subject in this embodiment is a construction terminal. The construction terminal used in the technical implementation of this application will be described below: The construction terminal includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the construction method in Embodiment 1 above.

[0054] The following is for reference. Figure 2 The diagram illustrates a structural schematic of a construction terminal suitable for implementing embodiments of this application. The construction terminal in these embodiments may include, but is not limited to, mobile terminals such as mobile phones, laptops, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Portable Application Descriptions), PMPs (Portable Media Players), and vehicle-mounted terminals (e.g., vehicle navigation terminals), as well as fixed terminals such as digital TVs and desktop computers. Figure 2 The construction terminal shown is merely an example and should not impose any limitations on the functionality and scope of use of the embodiments of this application.

[0055] like Figure 2 As shown, the construction terminal may include a processing device 1001 (e.g., a central processing unit, a graphics processing unit, etc.), which can perform various appropriate actions and processes according to a program stored in ROM 1002 (Read Only Memory) or a program loaded from storage device 1003 into RAM 1004 (Random Access Memory). RAM 1004 also stores various programs and data required for the operation of the construction terminal. The processing device 1001, ROM 1002, and RAM 1004 are interconnected via bus 1005. I / O (Input / Output) interface 1006 is also connected to the bus. Typically, the following systems can be connected to I / O interface 1006: input devices 1007 including, for example, touch screens, touchpads, keyboards, mice, image sensors, microphones, accelerometers, gyroscopes, etc.; output devices 1008 including, for example, LCDs (Liquid Crystal Displays), speakers, vibrators, etc.; storage devices 1003 including, for example, magnetic tapes, hard disks, etc.; and communication devices 1009. The communication device 1009 allows the construction terminal to communicate wirelessly or wiredly with other devices to exchange data. Although the figure shows construction terminals with various systems, it should be understood that it is not required to implement or possess all the systems shown. More or fewer systems may be implemented alternatively.

[0056] Specifically, according to the embodiments disclosed in this application, the processes described above with reference to the flowcharts can be implemented as computer software programs. For example, embodiments disclosed in this application include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the methods shown in the flowcharts. In such embodiments, the computer program can be downloaded and installed from a network via a communication device, or installed from storage device 1003, or installed from ROM 1002. When the computer program is executed by processing device 1001, it performs the functions defined in the methods of the embodiments disclosed in this application.

[0057] Step A20: Receive the updated 3D map of underground pipelines sent by the server; wherein the updated 3D map of underground pipelines is generated by the server based on the current geographical location information and the current underground pipeline burial information.

[0058] Step A30 displays the updated 3D map of underground pipelines, which serves as a reference for production scheduling of underground pipeline construction.

[0059] Understandably, by receiving and utilizing high-precision positioning technology to obtain current geographical location information, and then sending this information along with the current underground pipeline information to the server, the server can update the 3D map of underground pipelines using this information. This not only improves the display accuracy of the 3D map, reduces the deviation between the displayed pipelines and the actual pipelines, and avoids displaying incorrect 3D maps, thus providing accurate reference for the production scheduling of underground pipeline construction, but also achieves a WYSIWYG real-time display of the pipelines based on the current underground pipeline information and geographical location. During non-power construction, it eliminates the need for professional personnel to follow and check cable drawings on-site, improving work efficiency and ensuring operational safety.

[0060] For example, to help understand the implementation process of the construction method obtained by combining this embodiment with the above embodiment one, please refer to... Figure 3 , Figure 3 A simplified flowchart illustrating the construction method provided in this application embodiment is as follows: The RTK rover collects the current geographical location information of the construction area in real time and uploads it to the construction terminal. Construction personnel use the construction terminal to determine whether the construction area is suitable for underground pipeline construction based on the current geographical location information. If construction is deemed feasible, the construction personnel send a construction command to the construction terminal, simultaneously uploading the current underground pipeline information.

[0061] The construction terminal sends its current geographical location information and current underground pipeline information to the server according to the construction instructions. The server, based on the current underground pipeline information and the prefabricated pipeline model, generates a pipeline excavation model using an algorithm. This excavation model includes information on the excavation width and depth, as well as the construction unit's information. Then, based on the current geographical location information, the server integrates the pipeline excavation model into the underground pipeline 3D map to update the underground pipeline 3D map, thereby forming a digital twin model identical to the actual construction scenario (i.e., the updated underground pipeline 3D map).

[0062] The updated 3D map of underground pipelines can be updated and displayed in real time on the large screen of the server's command center, allowing technicians to understand the remote construction situation in real time, such as trenching operations at a certain construction location.

[0063] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the construction method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
