In addition, with the expansion of business, the system functions are insufficient, the system and data coverage are limited, and the real-life information model in a three-dimensional environment cannot be fully expressed, and it cannot be integrated with the three-dimensional model of the station. It cannot meet the requirements of digital delivery. Summary of the invention

[0004] The purpose of the present invention is to provide a long-distance pipeline design method that can improve design efficiency and visualization, and can enable various disciplines to design on a unified design platform to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A three-dimensional design method for a long-distance pipeline comprises: step S1, processing data provided by survey and measurement, and importing the data into a three-dimensional design platform to form a three-dimensional geological model and a three-dimensional terrain model; step S2, the line profession performs plane line selection and longitudinal section design on the basis of the three-dimensional geological model and the three-dimensional terrain model to form design results and a three-dimensional pipeline model, and publishes the design results and the three-dimensional pipeline model to downstream communication, water conservation and other professions for professional design; step S3, after the downstream profession completes the design of each profession, the design results and professional models of the profession are formed, and the design data is returned to the three-dimensional design platform for supplementation; step S4, all professional models of the downstream profession are integrated in the three-dimensional design platform to form a general model.

[0007] Preferably, step S1 comprises: using a drone with a medium format camera to shoot along the route to obtain high-definition image data and elevation and geographic coordinate data, and performing spatial three-dimensional calculations on these data to obtain a three-dimensional real-scene model; then extracting elevation-related elements and data from the three-dimensional real-scene model to form a three-dimensional terrain model; and collecting and analyzing the drilling data to obtain the stratification elements of the geological layer, geological type, stratum depth, soil coefficient, flood parameters, soil type and other parameters, and forming a three-dimensional geological model through calculation.

[0008] Preferably, the step S2 comprises: referencing the three-dimensional real scene model into the three-dimensional terrain model;

[0009] Select a route in the 3D terrain model; generate a corresponding longitudinal section model based on the selected route;

[0010] Set slope change points and crossing lines in the longitudinal section model.

[0011] Preferably, step 3 includes: extracting design data from the database to supplement the three-dimensional design platform; the data extracted from the database include: communication professional data, water conservation professional data, geological data; communication professional data include location data, identification and model data of optical cable laying, hand holes, crossings, markers, warning signs; water conservation professional data include identification, location and model data of cutoff walls, retaining walls, river revetments and other atypical structures; geological data include drilling data, geological pile foundation data, soil type data, flood level data, etc.

[0012] Preferably, the design results include: three-dimensional model, result file, and attribute data.

[0013] Preferably, the three-dimensional design platform is provided with a GIS integration interface, through which information is exchanged with the GIS platform to load the three-dimensional real scene model.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention adopts real-scene 3D map modeling technology and a 3D model processing engine, which can effectively be compatible with various types of measurement data such as aerial survey and oblique photography, and can realize 3D forward design of long-distance pipelines based on real-scene 3D maps.

[0016] The real-life modeling data created by real-life 3D map modeling technology can be applied to the field of long-distance pipeline project construction. The terrain data generated by the collected field data contains elevation information and spatial geographic location information, which helps designers analyze / master existing conditions, display projects in a real environment, easily convey design intent, and gain recognition from stakeholders more quickly. Due to its fast and simple technical characteristics of data collection and model generation, project managers can quickly obtain the actual situation on site at a low collection cost and high frequency, and achieve better risk management.

[0017] By using the real-life 3D map, a vectorized model can be generated through the real-life model, and combined with the parametric engineering model creation technology, the forward design process from 3D design to 2D output can be realized. At the same time, by using the extensible characteristics of digital engineering model information, the collected GPS coordinate information of pipeline welds, components, etc. can be accurately imported in batches, and the three-dimensional design results can be obtained for the later visualization of pipeline operations.

[0021] Step S2, the line professional performs plane line selection and longitudinal section design based on the three-dimensional geological model and the three-dimensional terrain model to form a design result and a three-dimensional pipeline model, and publishes the design result and the three-dimensional pipeline model to downstream communication, water conservancy and other professionals for professional design; in this step, the oblique photography data is first processed to form a three-dimensional real scene model and referenced into the three-dimensional terrain model to form a three-dimensional real terrain model; the line is selected in the three-dimensional real terrain model; according to the selected line, the corresponding longitudinal section model is generated; in the longitudinal section model, the slope points and crossing line data of different mileages are selected according to the preset specifications and parameters, and the three-dimensional design platform will dynamically calculate the parameters of the current buried depth point in real time, and display them in real time in the plane and superposition model space to help designers intuitively understand the currently determined buried depth position.

[0022] Step S3, after the downstream professional completes the design of each professional, the design results and professional models of the professional are formed, and the design data is returned to the three-dimensional design platform for supplementation; wherein, the design results include: three-dimensional model, result file, attribute data. The three-dimensional model includes a three-dimensional terrain model and a three-dimensional pipeline model; the result file includes but is not limited to the line horizontal and vertical synthesis map, steel pipe usage list, cold-bent pipe list, hot-bent pipe list, auxiliary engineering quantity list, etc.; the attribute data includes but is not limited to the mileage of the pipeline, the calculation angle of the bend, the wall thickness of the bend, the length of the bend curve, the orientation of the bend, etc. Specifically, the design data in the database is extracted to the three-dimensional design platform for supplementation; the data extracted from the database includes: communication professional data, water conservation professional data; communication professional data includes the location data, identification and model data of optical cable laying, hand holes, crossings, markers, and warning signs; water conservation professional data includes the identification, location and model data of cut-off walls, retaining walls, river revetments and other atypical structures; geological data includes: drilling data, geological pile foundation data, soil type data, flood level data, etc.
