Description

Technical Field

[0001] This invention relates to the field of highway positioning technology, specifically to a highway engineering simulation positioning method, system, and electronic equipment based on a BeiDou probe. Background Technology

[0002] In the field of highway construction, high-precision engineering surveying and rapid layout are the core foundation for ensuring smooth route alignment, accurate structure positioning, and construction progress. Currently, this field mainly relies on traditional Real-Time Kinematic (RTK) equipment to achieve centimeter-level positioning. However, the application of traditional RTK technology has significant limitations in long-distance, multi-section, and terrain-complex highway projects.

[0003] First, traditional RTK systems face significant economic and technical hurdles. The procurement cost of a complete RTK surveying system (including a GNSS receiver, data radio, centering pole, tripod, and other necessary components) typically ranges from tens of thousands to hundreds of thousands of yuan, placing a heavy burden on project budgets. More importantly, the system is complex to operate; the entire process, from equipment setup and coordinate system conversion to surveying and setting out, requires professionally trained technicians, leading to rigid human resource allocation and preventing ordinary construction workers from participating in surveying operations. Second, traditional equipment suffers from significant shortcomings in portability and adaptability. RTK equipment has numerous components, is bulky, and heavy, making it difficult to transport in complex terrain conditions (such as mountains, waterways, and densely built-up areas) and long-distance linear projects on highways, and resulting in lengthy equipment setup times. Furthermore, traditional methods heavily rely on preset coordinate system parameters. In project sites without known control points or historical coordinate system data, complex parameter calculation preparation work is required, severely impacting rapid response capabilities in emergency projects or projects in remote areas, making it difficult to meet the high-efficiency and rapid-response construction requirements of modern highway engineering.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0022] Example 1 This invention provides a method for simulating and locating highway engineering based on a BeiDou probe, such as... Figure 1 As shown, the specific steps include the following: S101, Establish communication connection between Beidou probe and mobile terminal; S102 uses BeiDou probes to collect real-world coordinate data of multiple feature points in the entire coverage area of ​​the project, which serves as the first coordinate data. S103, the first coordinate data is transmitted to the positioning matching model deployed on the mobile terminal for processing to obtain the second coordinate data; wherein, the second coordinate data is the mapping coordinate data of the first coordinate data in the engineering drawing coordinate system; S104, Based on the first coordinate data and the second coordinate data, perform the positioning of the engineering site on the mobile terminal.

[0023] In some embodiments, the communication connection in step S101 includes wired or wireless methods, wherein wireless communication may be implemented using at least one of Bluetooth, Wi-Fi or mobile networks.

[0024] In a preferred embodiment, the communication connection involved in this application is a connection established with a mobile terminal through the physical communication interface of the Beidou probe.

[0025] Specifically, it should be understood that this application preferably uses a Type-C interface to achieve bidirectional data transmission and device power supply. This solves the problem of traditional measurement equipment requiring independent power modules and establishes a stable data communication channel, enabling the BeiDou probe to directly utilize the power system and working platform of the mobile terminal, achieving a high degree of hardware integration and portability. In actual operation, when the BeiDou probe is connected to the mobile terminal via a data cable, the dedicated application on the terminal will automatically identify the device and establish a communication link. Users can monitor the connection status in real time through an intuitive interface. The entire process requires no professional technical personnel, significantly reducing the technical threshold for device use and laying the hardware foundation for subsequent data acquisition and processing.

[0026] In some embodiments, the number of the plurality of feature points mentioned in step S102 is at least three, and they cover the starting point, ending point, and critical path nodes of the entire project area.

[0027] Specifically, it should be understood that this application, based on the principle of minimum certainty in spatial coordinate transformation, ensures the accuracy of coordinate transformation by constructing a stable spatial geometric relationship. The starting and ending points serve as engineering baseline control points, establishing the spatial orientation and scale benchmarks for the entire project. Key path nodes (such as road bend vertices, pipeline turning points, and building outline control points) provide necessary spatial morphological constraints, collectively forming a control network that fully reflects the spatial characteristics of the project. This layout ensures consistent accuracy of the transformation model across the entire project, avoiding the accumulation of local errors caused by uneven distribution of control points. In practical applications, technicians collect the WGS-84 or CGCS2000 coordinates of these feature points sequentially on-site, according to the markings on the engineering drawings, forming the control point set required for spatial coordinate transformation. The feature point acquisition scheme involved in this application is suitable for the positioning needs of linear projects (such as roads, pipelines, and bridges). Through optimized control point configuration, it ensures centimeter-level positioning accuracy while minimizing fieldwork workload.

[0028] In some embodiments, the construction of the localization matching model in step S103, such as Figure 2 As shown, the specific steps include the following: S1031, Export the engineering layout CAD drawings in the mobile terminal as a DXF exchange format file; S1032, Based on the DXF exchange format file, obtain the design coordinate data of multiple feature points in the engineering drawing coordinate system; S1033, Collect the actual coordinate data of the multiple feature points at the engineering site through the Beidou probe; S1034, Generate conversion parameters between the design coordinate data and the actual coordinate data using a coordinate transformation algorithm to obtain mapping data between the design coordinate data and the actual coordinate data; S1035, Based on the mapping data, generate the positioning matching model.

[0029] This application, in S1031, employs a standardized data exchange format to ensure the complete transmission of geometric information, layer data, and coordinate systems from design drawings to the mobile terminal environment, establishing an accurate design benchmark for subsequent coordinate transformations. The choice of the DXF format fully considers its universality in the engineering field and its compatibility with various CAD software, effectively avoiding data loss or accuracy loss due to format incompatibility.

[0030] In step S1032, by parsing the metadata of the DXF file, the plane coordinates and elevation data of pre-labeled feature points (such as intersections of road centerlines, building corners, pipeline turning points, etc.) in the design coordinate system are accurately extracted. These design coordinates will serve as the reference data for coordinate transformation, and their accuracy directly affects the accuracy of the final positioning result.

[0031] In step S1033, the high-precision positioning capability of the BeiDou probe is utilized to measure the spatial position of the corresponding feature points on the drawing in the field, obtaining their three-dimensional coordinates in the WGS-84 or CGCS2000 coordinate system. To ensure data quality, a multi-epoch observation and averaging method is adopted during the acquisition process to effectively suppress random errors and ensure the reliability and stability of the field coordinate data.

[0032] The core step in step S1034 is to construct the positioning and matching model by establishing a mathematical transformation relationship between the design coordinate system and the actual coordinate system to achieve a precise mapping between the two coordinate systems.

[0033] In a preferred embodiment, the coordinate transformation algorithm in step S1034 includes an intelligent transformation algorithm or an associated point transformation algorithm.

[0034] In a preferred embodiment, the intelligent conversion algorithm specifically involves automatically matching coordinate zone parameters through the mobile terminal to generate the coordinate conversion parameters.

[0035] Specifically, it should be understood that the intelligent conversion algorithm is applicable to conventional engineering projects with standard coordinate zone parameters. By analyzing the distribution characteristics of coordinates on drawings and the spatial relationship between coordinates on the ground, it intelligently identifies the most suitable coordinate projection parameters and zone information, automatically completing the complex process of coordinate system unification. This greatly simplifies the operation process, significantly lowers the technical threshold for users, and enables non-professionals to quickly complete professional-level coordinate conversion work.

[0036] In another preferred embodiment, the associated point conversion algorithm, such as Figure 3 As shown, it includes the following steps: S10341, Input at least three sets of coordinate data for feature points; wherein, the coordinate data are control point coordinates in WGS-84 or CGCS2000 dual coordinate systems; S10342, Based on the at least three sets of coordinate data, the coordinate transformation parameters are generated analytically using the least squares method.

[0037] Specifically, it should be understood that the aforementioned correlation point transformation algorithm is suitable for special engineering scenarios where coordinate system parameters are unclear or higher transformation accuracy is required. Based on the least squares method principle of spatial coordinate transformation, it ensures that the transformation model has sufficient geometric constraints. The selection of the three sets of control points follows the principle of spatial uniformity and typically includes feature points at the starting point, ending point, and key intermediate locations of the project, in order to establish a stable spatial transformation benchmark. The coordinate transformation parameters are generated analytically using the least squares method, which can effectively adjust observation errors, improve the accuracy and stability of the transformation model, and ensure centimeter-level positioning accuracy throughout the entire project area.

[0038] In some embodiments, the engineering positioning in step S104 includes at least one of engineering layout, geographic information collection, and spatial data measurement.

[0039] In a preferred embodiment, the engineering layout includes at least one of red line layout, center line layout, foundation pit excavation line layout, point layout, and CAD drawing layout.

[0040] In a preferred embodiment, the geographic information collection includes one or more of the following: feature survey and site selection, area survey.

[0041] In terms of engineering layout, this application supports multi-level positioning needs, from macro-level redline and centerline layout to micro-level point layout. In particular, the direct layout function based on CAD drawings enables seamless digital integration between design drawings and on-site construction. In terms of geographic information collection, through an integrated data collection process, multiple tasks such as recording spatial attributes of ground features, surveying topographic feature points, and calculating regional area can be completed simultaneously, effectively avoiding the problems of setting up instruments multiple times and collecting data repeatedly in traditional operations. In terms of spatial data measurement, relying on the established precise coordinate framework, the spatial coordinates and relative positional relationships of any point to be measured can be obtained in real time.

[0042] Example 2 This invention provides a highway engineering simulation positioning system based on a BeiDou probe, such as... Figure 4 As shown, it includes the following modules: The data communication module is used to establish a communication connection between the Beidou probe and the mobile terminal. The data acquisition module is used to collect the real-world coordinate data of multiple feature points in the entire coverage area of ​​the project using the BeiDou probe, which serves as the first coordinate data. The data processing module is used to transmit the first coordinate data to the positioning matching model deployed on the mobile terminal for processing to obtain the second coordinate data; wherein, the second coordinate data is the mapped coordinate data of the first coordinate data in the engineering drawing coordinate system; The positioning execution module is used to perform positioning of the engineering site on the mobile terminal based on the first coordinate data and the second coordinate data.

[0043] This application employs a standardized interface design in its data communication module, ensuring stable data transmission between the BeiDou probe and the mobile terminal while achieving integrated power supply, effectively solving the technical challenges of complex wiring and independent power supply in traditional surveying equipment. The data acquisition module relies on my country's independent BeiDou navigation system, is compatible with multiple satellite signal sources, and ensures continuous and stable centimeter-level data acquisition capabilities through a professional-grade positioning chip. The data processing module innovatively adopts a dynamic matching algorithm to complete coordinate transformation calculations locally on the mobile terminal, not only eliminating reliance on professional surveying instruments but also overcoming the limitations of traditional methods based on preset coordinate system parameters. The positioning execution module, through intelligent task integration, standardizes and simplifies complex workflows such as engineering layout and geographic information collection, enabling non-professionals to complete professional surveying tasks. This modular system design reduces equipment costs to 1 / 20th of traditional solutions while maintaining professional-grade measurement accuracy, truly achieving a major breakthrough in the application of high-precision positioning technology from specialized fields to universal applications.
