Description

Technical Field

[0001] The present application relates to the technical field of automated route planning, and in particular to a high-speed rail carriage modeling method, device, equipment, storage medium, and computer program product. Background Art

[0002] In recent years, with the comprehensive development of China's high-speed rail technology, China's high-speed rail construction has seen a blowout and rapid growth. Among them, most of the passengers on the high-speed rail are mobile Internet users. In order to improve the quality of mobile communications during the high-speed rail, it is necessary to analyze the network status of the high-speed rail running on the high-speed rail line.

[0003] In the prior art, network simulation is a basic tool and important evaluation method for wireless network analysis, planning and design, and the accuracy of network simulation results is largely determined by the selected propagation model. Among them, the 3D ray tracing model uses optical methods, taking into account the reflection, diffraction and scattering of radio waves, combined with high-precision three-dimensional electronic maps (including building vectors and building heights), to accurately predict propagation losses. It is also the most commonly used propagation model. According to the principle of the 3D ray tracing model, how to accurately construct a 3D map will directly affect the accuracy of the 3D ray tracing model.

[0004] The existing network simulation 3D electronic map is mainly generated by generating building vector outlines through satellite aerial pictures after image recognition processing, and calculating the building height by combining the relative height of the shadow of the building projection. However, for the high-speed rail network simulation analysis scenario, since the effective users are all inside the carriage, the high-speed rail carriage needs to be 3D modeled during the simulation. During the operation, the high-speed rail trains are moving at high speed. Therefore, the conventional satellite image modeling method can only obtain the high-speed rail route map, but cannot directly obtain the 3D model of the high-speed rail carriage, which makes it impossible to accurately simulate the network of the high-speed rail carriage using the existing technology.

[0005] It can be seen that how to perform 3D modeling of high-speed rail carriages in operation has become a technical problem that needs to be urgently solved in related fields. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0025] A high-speed rail car modeling method provided in an embodiment of the present application is used to solve the problem that the prior art cannot accurately perform network simulation on high-speed rail cars.

[0026] The executor of the high-speed rail car modeling method provided in the embodiment of the present application may be, but is not limited to, at least one of a modeling server, a network simulation server, or a network operation and maintenance server; in addition, the executor of the method may also be an application (Application, APP) running on these servers or the system itself.

[0027] For ease of description, the following takes the execution subject of the method as a network simulation system as an example to introduce the implementation of the method. It can be understood that the execution subject of the method as a network simulation system is only an exemplary description and should not be understood as a limitation of the method.

[0028] The specific implementation flow chart of the high-speed rail carriage modeling method provided in this application is as follows Figure 1 As shown, it mainly includes the following steps:

[0029] Step 11, obtaining the high-speed rail line on which the high-speed rail carriage to be modeled runs;

[0030] It should be noted here that for high-speed rail lines that have been built and put into operation, a vector route map corresponding to the high-speed rail line is generally stored in the railway management system. In this case, when it is necessary to model the high-speed rail running on the high-speed rail line, the high-speed rail line can be directly obtained from the railway management system.

[0031] For high-speed rail lines that do not have vector route maps or have not been built, the high-speed rail lines corresponding to the high-speed rail carriages to be modeled can be generated on a GIS map built based on the Geographic Information System (GIS) based on the high-speed rail lines captured by satellite aerial photography (or the planned high-speed rail lines).

[0032] Specifically, in the embodiment of the present application, for a high-speed rail line that has no vector line diagram or has not been built, the network simulation system can generate the corresponding high-speed rail line according to the following steps, including:

[0033] Sub-step 1101, obtaining a satellite aerial image corresponding to the high-speed rail carriage to be modeled;

[0034] It should be noted here that for high-speed rail lines that have been built but not opened to traffic (or for which a vector route map has not yet been generated), satellite aerial photography can be used to obtain satellite aerial photos of the high-speed rail line so that subsequent high-speed rail vector route maps can be generated based on the aerial photos.

[0035] For the high-speed rail lines that have not been built, the planning data of the high-speed rail lines can be obtained, and based on the planning data of the high-speed rail lines, the corresponding high-speed rail vector line map can be generated.

[0036] Sub-step 1102, determining the running path of the high-speed rail carriage to be modeled according to the satellite aerial image obtained by executing sub-step 1102;

[0037] Specifically, the network simulation system can determine the running path of the high-speed rail carriage to be modeled based on the satellite aerial photos, and determine the geographical location coordinates (such as longitude and latitude values) corresponding to the key points on the running path.

[0038] Sub-step 1103, generating the high-speed rail line on a geographic information system (GIS) map according to the running path.

[0039] Specifically, the network simulation system can create a map layer and a drawing layer, and apply for resources from the system to create a drawing container. Then, the network simulation system can request the map data corresponding to the province or city area according to the province or city area passed by the running path, and draw the map of the area passed by the high-speed rail running path through the drawing container to obtain the map layer.

[0040] Next, the network simulation system can draw the key points at corresponding positions on the drawing layer according to the geographical location coordinates of the key points on the running path, and connect the key points to form a high-speed rail line.

[0041] Finally, the generated map layer and the drawing layer are superimposed to complete the drawing of the entire high-speed rail vector line map on the GIS map.

[0042] Step 12, determining the body model of the high-speed rail carriage to be modeled, and determining the carriage width and carriage height of the high-speed rail carriage to be modeled according to the body model;

[0043] Generally, the railway management system stores the carriage parameter information of various types of high-speed railways currently operating on the market. In this embodiment of the present application, the network simulation system can determine the body model of the high-speed railway carriage to be modeled, and search the railway management system for the corresponding carriage width and carriage height of the high-speed railway carriage based on the body model.

[0044] Step 13, according to the width of the carriage and the high-speed rail line, a plane vector graphic corresponding to the high-speed rail carriage to be modeled is established in the simulation software;

[0045] In one embodiment, the simulation software applicable to the embodiment of the present application may be Atoll simulation software. Atoll simulation software supports multiple wireless access technologies such as NR, LTE, UMTS, GSM, etc., and can effectively support 5G network modeling, coverage prediction, network planning and optimization and other functions.

[0046] In an embodiment of the present application, the network simulation system can import the high-speed rail line vector diagram obtained by executing step 11 into the Atoll simulation software. In the Atoll simulation software, the high-speed rail line vector diagram is displayed as a vector line segment. Through the Atoll simulation software, at least two coordinate points on the vector line segment corresponding to the high-speed rail line can be determined. Then, the Atoll simulation software can offset each coordinate point on the vector line segment according to the width of the car, and then generate a plane vector graphic corresponding to the high-speed rail car to be modeled based on the contour point coordinates obtained after the offset.

[0047] In one embodiment, the specific implementation method of step 13 may include: obtaining at least two coordinate points on the high-speed rail line; offsetting the coordinate points according to the car width and the high-speed rail line to obtain the contour point coordinates corresponding to the high-speed rail line; and establishing a plane vector graphic corresponding to the high-speed rail car to be modeled in the simulation software according to the contour point coordinates.

[0048] It should be noted here that the network simulation system can take the vector line segment corresponding to the high-speed rail line vector diagram in the Atoll simulation software as the center, take the direction perpendicular to the vector line segment as the offset direction, take the width of the carriage as the offset distance, and offset each coordinate point on the vector line segment to obtain the contour points corresponding to each coordinate point on the vector line segment. Specifically, in the embodiment of the present application, the network simulation system can calculate and determine the offset distance corresponding to each coordinate point according to the following formula [1]:

[0049]

[0050] Wherein, N is the number of coordinate points determined by the Atoll simulation software on the vector segment.

[0051] In an embodiment of the present application, the network simulation system can specifically perform offset processing on each coordinate point on the vector line segment corresponding to the high-speed rail line according to the following method, including: determining the offset distance for the coordinate point according to the carriage width; determining the offset direction of the coordinate point with respect to the high-speed rail line; offsetting the coordinate point according to the offset distance and the offset direction to obtain the contour point coordinates corresponding to the high-speed rail line.

[0052] After determining the offset distance corresponding to each coordinate point on the vector line segment corresponding to the high-speed rail line by the above method, and completing the offset of each coordinate point on the vector line segment according to the offset distance and obtaining the contour points, the network simulation system connects these contour points to obtain the plane vector graphics corresponding to the high-speed rail car to be modeled.

[0053] Step 14, based on the carriage height determined by executing step 12 and the plane vector graphics generated by executing step 13, establish a 3D model corresponding to the high-speed rail carriage to be modeled in the simulation software.

[0054] In an embodiment of the present application, the simulation software can assign a height value to the generated plane vector graphics according to the height of the carriage, and then establish a 3D model corresponding to the high-speed rail carriage.

[0055] In addition, after generating the corresponding 3D model of the high-speed rail car, the network simulation system can also determine the corresponding material parameters of the car (such as body structure, body material, window glass material, etc.) according to the body model of the high-speed rail car, and set the parameters such as penetration loss and linear loss for the high-speed rail car separately according to the material parameters of the car. Then, based on the generated 3D model and the set parameters, the 3D ray tracing model completes the network simulation analysis of the high-speed rail car.

[0056] By adopting the high-speed rail car modeling method provided in the embodiment of the present application, for the high-speed rail car to be modeled, the high-speed rail line on which the high-speed rail car to be modeled runs can be first obtained, and the body model of the high-speed rail car to be modeled can be determined, and the car body model of the high-speed rail car to be modeled can be determined according to the car body model. The car width and car height of the high-speed rail car to be modeled are determined, and according to the car width and the high-speed rail line, the plane vector graphics corresponding to the high-speed rail car to be modeled are established in the simulation software, and then according to the car height and the plane vector graphics, the 3D model corresponding to the high-speed rail car to be modeled is established in the simulation software. By adopting the method provided in the embodiment of the present application, the simulation software can extract the high-speed rail line map, and according to the high-speed rail line map, the width of the high-speed rail car and the height data of the high-speed rail car, a 3D model of the high-speed rail car in operation is generated in the model that originally only contains the building vector map, so that the model contains the overall high-speed rail car information on the high-speed rail line, so that the generated 3D model can more accurately simulate the actual environment of the high-speed rail operation line, so that according to the 3D model, the simulation analysis of the high-speed rail network signal in operation can be more accurately realized.

[0057] In one embodiment, the present application also provides a high-speed rail carriage modeling device to solve the problem that the prior art cannot accurately perform network simulation on high-speed rail carriages.

[0062] The 3D modeling unit 25 is used to establish a 3D model corresponding to the high-speed rail carriage to be modeled in the simulation software according to the height of the carriage and the plane vector graphics.

[0064] In one embodiment, the plane modeling unit 23 is specifically used to: obtain at least two coordinate points on the high-speed rail line; offset the coordinate points according to the carriage width and the high-speed rail line to obtain the contour point coordinates corresponding to the high-speed rail line; and establish a plane vector graphic corresponding to the high-speed rail carriage to be modeled in the simulation software according to the contour point coordinates.

[0066] In one embodiment, the plane modeling unit 23 is specifically used to: sequentially connect the contour point coordinates in the simulation software to obtain a plane vector graphic corresponding to the high-speed rail carriage to be modeled.
