DETAILED DESCRIPTION

[0018] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the drawings.

[0019] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] As Figure 1 A flow chart of a railway electronic map construction method provided by an embodiment of the present application is shown in the figure. Referring to Figure 1 The steps of the method include: S101, constructing a target element, the target element including a station yard node, a boundary point, a main line and a connecting line.

[0021] Specifically, the station yard node is used to represent a station or a yard in the railway electronic map. The station yard node specifically includes a first station yard node and a second station yard node. The first station yard node is used to represent a station, and the second station yard node is used to represent a yard or a turnout inside the station.

[0022] The demarcation point is an end point of the station yard node and is used as an end point for connecting various station yard nodes in the railway electronic map. The demarcation point is arranged at the left end and / or the right end of the station yard node. The number of demarcation points included in each station yard node is equal to the number of main lines or connecting lines connected to the station yard node. For example, when the station yard node is a first station yard node, the number of demarcation points of the first station yard node is equal to the number of all main lines in the section between the first station yard node and an adjacent station yard node.

[0023] The demarcation point is also provided with a corresponding inner control point and an outer control point. The demarcation point connects the main line or the connecting line through the inner control point or the outer control point in different scenarios. The inner control point is arranged on the inner side of the demarcation point relative to the station yard node, and the outer control point is arranged on the outer side of the demarcation point relative to the station yard node.

[0024] The distance between the inner control point or the outer control point and the demarcation point is determined by a control point distance ratio.

[0025] The main line is used to connect different stations based on the demarcation point, and the connecting line is used to connect the yards inside the station based on the demarcation point. The main line and the connecting line are paths connecting between stations or yards and are both directed line segments, which can be used to represent the direction of train travel.

[0026] S102, constructing a railway electronic map based on the target elements, the railway electronic map including a macroscopic view, a mesoscopic view and a microscopic view.

[0027] Specifically, the macroscopic view is used to represent an inter-station structure, the mesoscopic view is used to represent a station yard structure, and the microscopic view is used to represent an intra-station structure.

[0028] In the macroscopic view, specifically includes a station site mode and a yard mode.

[0029] In the station site mode, the station yard node only includes a plurality of first station yard nodes, and does not include a second station yard node. The first station yard nodes are connected by main lines, and the main lines are connected to the outer control points of the first station yard nodes.

[0030] In the embodiment of the present application, the first station yard node can be represented by any shape, for example, can be represented by a circle or a rectangle. The shape of the first station yard node can be replaced according to different types or different functions of the station, so as to distinguish different types or different functions of the station.

[0031] The size of each first station yard node is determined according to the number of yards contained in the corresponding first station yard node, and the more yards contained in the first station yard node, the larger the shape of the first station yard node. Alternatively, two sizes of shapes can be provided, and a larger size of the first station yard node is used when the first station yard node contains yards, and a smaller size of the first station yard node is used when the first station yard node does not contain yards.

[0032] The main line can be represented by a broken line or a Bezier curve.

[0033] As shown in Figure 2A , a specific railway electronic map provided by the embodiment of the present application is a station mode in a macroscopic perspective.

[0034] Referring to Figure 2A , in this embodiment, the railway electronic map contains five stations, i.e., station 1, station 2, station 3, station 4 and station 5, which are all represented by first station yard nodes. Each first station yard node is represented by a circle, and the circles are set to different shapes according to different functions and types of the stations.

[0035] Since station 1 and station 2 contain yards, and station 3, station 4 and station 5 do not contain yards, the first station yard nodes of station 1 and station 2 are represented by larger circles, and the first station yard nodes of station 3, station 4 and station 5 are represented by smaller circles.

[0036] The right end of the first station yard node representing station 1 and the left end of the first station yard node representing station 2 are both provided with four demarcation points, and four main lines are connected to the outer control points at the demarcation points to realize the connection between station 1 and station 2. The connection modes between the remaining stations are similar.

[0037] In the embodiment of the present application, different types of stations can also be represented by different forms of circles.

[0038] As shown in Figure 2B , a station legend provided by the embodiment of the present application is provided. The station legend is applied to the railway electronic map of the station mode in a macroscopic perspective as shown in Figure 2A , and is used to distinguish the types of the stations in the railway electronic map.

[0039] Referring to Figure 2B , different types of stations can be represented by different forms of circles, including passenger stations, passenger and freight stations, freight stations, intermediate stations, section stations, marshalling stations, line stations, EMU depots, passenger drop-off and pickup stations, line connection points, passing stations and other types of stations.

[0040] Based on the legend as shown in Figure 2B , the railway electronic map of the station mode in a macroscopic perspective as shown in Figure 2AIn the provided railway electronic map, station 1 is a passenger and freight depot, station 2 is a section station, station 3 is a passenger station, station 4 is a freight station, and station 5 is a line junction.

[0041] In the field-specific mode, the station nodes include several first station nodes and several second station nodes, with each second station node contained within its corresponding first station node. The second station nodes are not connected by wires, while the connection relationships between the first station nodes are the same as in the station-specific mode.

[0042] In this embodiment of the invention, the first station node and the second station node can be represented by any shape, such as a circle or a rectangle.

[0043] like Figure 3 As shown, this is a specific railway electronic map provided in an embodiment of the present invention. The railway electronic map is a field-division mode from a macroscopic perspective.

[0044] See Figure 3 Based on the station pattern, the first station node containing the parking lot is replaced with a large rectangle, and the parking lot within the first station node is represented by a small rectangle.

[0045] That is, the first station yard nodes of Station 1 and Station 2 are represented by large rectangles, and the first and second yards contained in Station 1 are represented by small rectangles, as are the second station yard nodes of the first, second yards and the east main branch contained in Station 2. Stations 3, 4 and 5, which do not contain a yard, are still represented by circles.

[0046] The connections between stations are the same as the station pattern, still connecting to the main line through the station's external control points.

[0047] The railway electronic map from a meso-level perspective is in route mode, which allows you to view the connections between stations, the connections between train depots, and the connections between stations and train depots.

[0048] Specifically, from a meso-level perspective, station nodes include several first station nodes and several second station nodes, and each second station node is contained within its corresponding first station node.

[0049] The first station yard nodes are connected by a main line, which connects to the internal control point of each first station yard node; the second station yard nodes are connected by a connecting line, which connects to the external control point of each second station yard node; the first station yard nodes and the second station yard nodes are connected by a connecting line, which connects to the internal control point of each first station yard node and the external control point of each second station yard node or the first station yard node that does not include a train yard.

[0050] In the second station node, or the first station node not containing the second station node, the track of each station node is also contained.

[0051] In the embodiment of the present application, the first station node and the second station node can be represented by any shape, for example, can be represented by a rectangle or a hexagon. The size of the second station node, or the first station node not containing the second station node, is determined by the number of tracks contained, and the more tracks it contains, the larger the shape size. Alternatively, if the track data of the corresponding station is missing, the size of the station node is determined by the default number of tracks. Alternatively, when the second station node is a turnout area without tracks, the size of the second station node is smaller than that of other normal second station nodes.

[0052] For example, when the second station node, or the first station node not containing the second station node, is represented by a hexagon, the width of the hexagon is fixed, and the height is proportional to the number of tracks contained. If the second station node is a turnout area, its width is half of the normal width, and the height is represented by the default number of tracks.

[0053] The connection line can be represented by a polyline or a Bezier curve.

[0054] Alternatively, in order to avoid the interference of the main line between stations in the connection relationship between stations, or to avoid the railway electronic map being too cluttered in the mesoscopic view, the first station node can be hidden based on user instructions.

[0055] As shown in Figure 4 , a specific railway electronic map provided by the embodiment of the present application is provided, and the railway electronic map is in a mesoscopic view.

[0056] Referring to Figure 4 , the station 1 and the station 2 contain yards, and the station 3, the station 4 and the station 5 do not contain yards, so the first station node of the station 1 and the station 2 is represented by a large rectangular frame (the first station node of the station 1 is hidden), the second station node of the yard 1, the yard 2 in the station 1, and the yard 1, the yard 2 and the east turnout in the station 2 are represented by a hexagon, and the first station node of the station 3, the station 4 and the station 5 is represented by a hexagon.

[0057] When viewing the yard connection relationship between the yard 2 in the station 1 and the yard 2 in the station 2, the right side of the yard 2 in the station 1 and the left side of the yard 2 in the station 2 contain two demarcation points, which are connected to the outer control points of the yard 2 in the station 1 and the outer control points of the yard 2 in the station 2 by two connection lines (as shown in Figure 4 , the outer control point 1 outside the demarcation point 1 at the right end of the yard 2 in the station 1 is connected to the outer control point 2 outside the demarcation point 2 at the left end of the yard 2 in the station 2 by a connection line).

[0058] In the view of the connection relationship between the second yard of station 1 and station 2, the right side of the second yard of station 1 and the left side of station 2 contain two demarcation points, which are connected to the outer control point of the second yard of station 1 and the inner control point of station 2 respectively through two connection lines (as shown in Figure 4 In the view of the connection relationship between the second yard of station 1 and station 2, the right side of the second yard of station 1 and the left side of station 2 contain two demarcation points, which are connected to the outer control point of the second yard of station 1 and the inner control point of station 2 respectively through two connection lines (as shown in

[0062] The connection mode between the remaining stations is similar.

[0063] In the micro view, the internal structure of each first station yard node in the above meso view is specifically displayed through the micro station yard structure.

[0064] The micro station yard structure is composed of micro nodes and micro line segments, and the micro nodes are used to divide the section composed of the micro line segments. The micro nodes are specifically determined according to the demarcation points and the positions of the entry signal and the reverse entry signal in the first station yard.

[0065] As shown in Figure 5 , the railway electronic map provided by the embodiment of the present application is a micro view.
