[0038] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present invention and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present invention.
[0039] Embodiment 1
[0040] like Figure 1 As shown, an embodiment of the present invention provides a method for correcting the position of a railway locomotive, comprising the following steps S101 to S104:
[0041] Step S101: Collecting target locomotive position information.
[0042] For example, the longitude and latitude coordinate information of the locomotive's current position is obtained through the Beidou system.
[0043] Step S102: acquiring the corresponding target locomotive mileage value on the target railway electronic map according to the target locomotive position information.
[0044] For example, determining whether the latitude and longitude coordinates of the target locomotive are located in the target operating route of the target railway electronic map;
[0045] If the longitude and latitude coordinates of the target locomotive are not located in the target running route of the target railway electronic map, obtaining a target projection point of the longitude and latitude coordinates of the target locomotive in the target running route of the target railway electronic map;
[0046] For example, the position where the latitude and longitude coordinates of the target locomotive are closest to the target running line of the target railway electronic map is obtained as the target projection point.
[0047] For example, the target running route of the target railway electronic map is cut according to a preset distance to obtain target running route segments;
[0048] Based on the latitude and longitude coordinates of the target locomotive, a perpendicular line is drawn to the target running line section, and the foot of the perpendicular line closest to the target projection point is the target projection point. Figure 4As shown, the satellite signal is received by the Beidou satellite receiver to obtain the longitude and latitude coordinates of the current position of the locomotive. According to the precise coordinates of the locomotive position point after the solution, the corresponding line segment is found on the railway electronic map, and the locomotive position point is perpendicular to the line segment. The perpendicular point is the projection position of the locomotive position point on the railway line. Through the data information of the railway electronic map itself, the corresponding mileage information of the locomotive projection position point on the line is found. The target projection point calculation process is as follows: the line data is divided into n segments, and the start and end of each segment are k0~k1, k1~k2,..., and so on, and each segment is 1 kilometer long. Determine whether the longitude and latitude point is on the line. If not, calculate the nearest point from the longitude and latitude point to the line data, that is, draw a perpendicular line from the longitude and latitude point to the line to obtain the foot of the perpendicular. Get the interval of the line segment where the foot of the perpendicular is located, for example: k1~k2, and calculate the distance from the start k1 of the interval to the foot of the perpendicular, and you can get the mileage point.
[0049] The target locomotive mileage value corresponding to the target railway electronic map is obtained according to the target projection point. For example, the target locomotive mileage value is obtained based on the distance between the starting position of the target running line section and the target projection point. For example, the starting position of the target running line section is K98, and the distance from the target projection point is 350, then the target locomotive mileage value is K98+350.
[0050] Step S103: Obtain the target locomotive mileage point coordinate value according to the target locomotive mileage value.
[0051] For example, based on the mileage information of the locomotive's projected position point on the line, the actual coordinates of the locomotive's mileage point are calculated through the mapping relationship between the mileage point on the railway electronic map and the geodetic coordinates; the locomotive's icon position on the railway electronic map is displayed in real time based on the obtained coordinate data of the mileage point on the corresponding line of the locomotive, thereby completing the position correction of the locomotive displayed in real time on the railway electronic map.
[0052] For example, the input mileage value is K98+350, and the output is the corrected longitude 3901.456789 and the corrected latitude 11102.567845.
[0053] The positioning and deviation correction method proposed in the present invention can reasonably display the locomotive position on the railway electronic map, and more accurately display the actual driving status of the railway locomotive. After a series of technical means such as point-to-point mileage and mileage-to-point mileage are used to locate the positioning data, a reasonable display of the positioning position is achieved, and the normal train can be ensured to run stably on the track on the real-time railway electronic map.
[0054] The present invention can more reasonably display the real-time position of the locomotive on the railway electronic map, and to a large extent avoid the unreasonable display of the locomotive position when the position data of the on-board satellite positioning terminal has a large deviation.
[0055] Step S104: Obtain the longitude and latitude of the target locomotive mileage point according to the coordinate value of the target locomotive mileage point.
[0056] For example, the longitude and latitude of the target locomotive mileage point are calculated through the mapping relationship between the coordinate value of the target locomotive mileage point and the geodetic coordinates.
