Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a method for acquiring a route point parameter according to an embodiment of the present invention, which is applicable to a case where a route point parameter is reversely derived according to a distance. As shown in fig. 1, the method specifically includes the following steps:
Wherein the input point and the target point are given two known points located on the route, and the known distance between the input point and the target point is calculated in advance. The distance between the input point and the line starting point can be obtained according to the input parameter of the input point, the input parameter can be a milestone of the input point, and the milestone can be used for representing the distance between the line point and the line starting point. For example, if the mileages on the route are labeled "10", "20", and "30" and the input parameter of the input point is "20", the preset route distance of the input point from the start point of the route can be determined to be 20 km. According to the preset line configuration, whether a long chain exists between the input point and the line starting point or not can be determined, and if the long chain exists, the distance between the input point and the line starting point is determined to be the sum of the preset line distance and the long chain distance. The route is configured as information determined after the route is constructed, and can indicate segments and long chains included in one route. The distance between the target point and the starting point of the route can be determined from known parameters of the target point, which can be an odometer for the target point, given by the user. According to the distance between the input point and the line starting point and the distance between the target point and the line starting point, the distance between the input point and the target point can be determined, and the direction of the target point at the input point can also be determined. The line configuration direction may be preset, for example, the line configuration direction is a-B-C-D-E, the input point is point C, if the target point is point D, the target point is determined to be located in front of the input point, and if the target point is point B, the target point is determined to be located behind the input point.
After the distance between the input point and the target point and the distance direction are obtained, the distance is taken as a known distance, and the distance direction is taken as a known distance direction. In order to ensure that the known distance is calculated correctly, the parameters of the target point can be reversely deduced through the known distance, and if the reversely deduced target parameters are consistent with the known parameters of the target point, the known distance is calculated correctly. And determining the distance between the input point and the starting point of the line according to the input parameters of the input point. For example, three milestones of "10", "20" and "30" are set on a segment of the line, the segment may contain a long chain, the input parameter of the input point is "20-2", the parameter contains a long chain mark, which indicates that a long chain exists at the milestone of "20", the input point is located within the long chain, the distance between the input point and the starting point of the long chain is 2 km, the distance between the starting point of the long chain and the starting point of the segment is 20 km, and if no long chain exists in the line between the milestone of "10" and the starting point of the long chain, the distance between the input point and the starting point of the segment is determined to be 22 km. The distance between the input point and the starting point of the route is the distance between the input point and the starting point of the segment plus the distance between the starting point of the segment and the starting point of the route.
After the distance between the input point and the line starting point is determined, a first distance between the target point and the line starting point is obtained according to the known distance and the known distance direction between the input point and the target point. For example, if the known distance direction is that the target point is located in front of the input point, the first distance is the known distance plus the distance between the input point and the starting point of the route.
In this embodiment, optionally, the determining a first distance between the target point and the start point of the route according to the known distance between the input point and the target point, the known distance direction, and the input parameter of the input point includes: determining a fourth distance between the input point and the starting point of the line according to the input parameters of the input point; and obtaining a first distance between the target point and the starting point of the line according to the known distance between the input point and the target point, the known distance direction and the fourth distance.
Specifically, the fourth distance is a distance between the input point and the line start point. Each line is configured with a preset line distance, the preset line distance is a line length determined when the line is planned, and differences often exist when the line is actually built, for example, a long chain may appear on the line, and the length of the long chain is a distance beyond the preset line distance. And if the input point and the starting point of the line do not contain the long chain, determining the section of the line where the input point is located, and adding the distance between the input point and the starting point of the section and the distance between the starting point of the section and the starting point of the line to obtain a fourth distance. If the long chain exists between the input point and the starting point of the line, determining whether the input point is positioned in the long chain according to the input parameters of the input point, and determining whether the long chain exists between the input point and the starting point of the segment and whether the long chain exists between the starting point of the segment and the starting point of the line according to the line configuration. And if the input point is determined to be positioned in the long chain, determining the distance between the input point and the starting point of the long chain. And determining the distance between the long-chain starting point and the segment starting point, wherein if the long chain exists between the long-chain starting point and the segment starting point, the distance is the sum of the preset line distance between the long-chain starting point and the segment starting point and the long-chain distance between the long-chain starting point and the segment starting point. And determining the distance between the segment starting point and the line starting point, wherein if the segment starting point and the line starting point contain long chains, the distance is the sum of the preset line distance between the segment starting point and the line starting point and the long chain distance between the segment starting point and the line starting point. The sum of the distances between the input point and the starting point of the line is the fourth distance.
After the fourth distance is obtained, calculating to obtain a first distance between the target point and the starting point of the line according to the known distance between the input point and the target point and the known distance direction. The beneficial effect who sets up like this lies in, when carrying out the backstepping according to the distance, only need know input parameter and known distance information can, according to input information, can obtain the accurate distance between input point and the circuit starting point, improve the definite efficiency of circuit distance, practice thrift the calculating time, improve the backstepping efficiency and the precision of parameter.
In this embodiment, optionally, obtaining the first distance between the target point and the line starting point according to the known distance between the input point and the target point, the known distance direction, and the fourth distance includes: if the known distance direction is the same as the line configuration direction, adding the known distance to the fourth distance to obtain a first distance between the target point and the starting point of the line; if the known distance direction is opposite to the line arrangement direction, subtracting the fourth distance from the known distance to obtain a first distance between the target point and the starting point of the line.
Specifically, each line is preset with a line configuration direction, and the line configuration direction is fixed and is irrelevant to the actual running direction of the train on the line. For example, the route is configured from a to B, and the actual running direction of the train on the route may be from a to B or from B to a. The known distance direction is a direction from the input point to the target point, and if the known distance direction is consistent with the route arrangement direction, the target point is in front of the input point, that is, the train passes through the input point and then passes through the target point when traveling according to the route arrangement direction. And adding the fourth distance to the known distance to obtain the first distance between the target point and the starting point of the line.
If the known distance direction is opposite to the line configuration direction, i.e. the target point is behind the input point, the fourth distance should be greater than the first distance, and therefore, the known distance is subtracted from the fourth distance to obtain the first distance between the target point and the line starting point. The method has the advantages that the direction of the known distance is distinguished, the first distance is prevented from being calculated wrongly, the distance calculation precision is improved, and the parameter detection precision is further improved.
And step 120, determining a second distance between the section boundary and the line starting point and a third distance between the long-chain boundary and the line starting point according to configuration information of the section boundary and the long-chain boundary on the line.
The configuration information of the line points on the line is obtained by pre-configuration, and the sectional boundary points and the long-chain boundary points are line boundary points in the line points on the line. The configuration information of the segment boundary may be represented by a milestone at the segment boundary, and the configuration information of the long-chain boundary may be represented by a milestone at the long-chain boundary. The segmentation boundary may be the start or end of a segment and the long chain boundary may be the start or end of a long chain. According to the configuration information of the line points, the distance between the line point and the line starting point can be obtained, the distance between the segment boundary and the line starting point is used as a second distance, and the distance between the long-chain boundary and the line starting point is used as a third distance.
In this embodiment, optionally, determining a second distance between the segment boundary and the line starting point and a third distance between the long-chain boundary and the line starting point according to configuration information of the segment boundary and the long-chain boundary on the line includes: determining the information of a segment starting point, the information of a segment end point, the information of a long chain starting point and the information of a long chain end point on the line according to the configuration information of the segment boundary and the long chain boundary on the line; determining a second distance between the segmentation boundary and the line starting point according to the segmentation starting point information and the segmentation end point information; the second distance comprises a fifth distance between the segmentation starting point and the line starting point and a sixth distance between the segmentation ending point and the line starting point; determining a third distance between the long-chain boundary and the line starting point according to the long-chain starting point information and the long-chain end point information; wherein the third distance includes a seventh distance between the long chain start point and the line start point, and an eighth distance between the long chain end point and the line start point.
Specifically, the number of segments and the number of long chains on the line can be determined according to the configuration information of segment boundary points and the configuration information of long chain boundary points on the line, wherein one segment corresponds to one segment starting point and one segment ending point, and one long chain corresponds to one long chain starting point and one long chain ending point. The configuration information of the segmentation boundary may include segmentation start point information and segmentation end point information, and the configuration information of the long-chain boundary may include long-chain start point information and long-chain end point information. According to the configuration information, the second distance and the third distance can be directly obtained. The second distance and the third distance are actual distances from the line boundary point to the line starting point in the line, and if the line boundary point to the line starting point contains a long chain, the distance between the line boundary point and the line starting point needs to be added with the contained long chain distance when the second distance and the third distance are calculated. The presence of long chains in the line and the determination of the distance of the long chains can be predetermined and stored.
The second distance is the distance between the segment boundary and the starting point of the route, and there may be a plurality of second distances in one route, and each segment has two second distances, that is, the distance between the segment starting point and the starting point of the route, and the distance between the segment ending point and the starting point of the route. The distance between the segment start point and the route start point is taken as a fifth distance, the distance between the segment end point and the route start point is taken as a sixth distance, and the second distance may include at least one fifth distance and at least one sixth distance.
The third distance is a distance between a long chain boundary and a line starting point, the long chain is positioned in the segment, a plurality of long chains can exist in one segment, namely, a plurality of third distances can exist in one segment. Each long chain has two third distances, and the third distances comprise the distance between the long chain starting point and the line starting point and the distance between the long chain end point and the line starting point. The distance between the long chain starting point and the line starting point is a seventh distance, the distance between the long chain end point and the line starting point is an eighth distance, and the third distance may include at least one seventh distance and at least one eighth distance.
FIG. 2 is a schematic illustration of the segmentation and elongation in an embodiment of the present invention. The point from x to y is a segment, the point from m to n is a long chain in the segment, x is a segment starting point, y is a segment end point, m is a long chain starting point, and n is a long chain end point. The distance from the point x to the line starting point is a fifth distance, the distance from the point y to the line starting point is a sixth distance, the distance from the point m to the line starting point is a seventh distance, and the distance from the point n to the line starting point is an eighth distance. The line start point is a point outside the segment, in front of point x. The method has the advantages that the number of intervals on the line can be determined, the segmentation boundary points and the long-chain boundary points can be special points in the line points, namely line boundary points, and the part between every two special points is an interval. By determining the second distance and the third distance, the distance ranges of different intervals can be determined, which is beneficial to subsequently determining the interval where the target point is located. The division of the line interval is realized by dividing the line boundary point, and because the parameters of the start point and the end point of the interval in the interval are unified, namely both long chain marks with the same long chain or both long chain marks are not provided, the acquisition of the target point parameter is realized by converting the target point into the distance and performing linear calculation after matching the divided interval.
And step 130, determining a target interval where the target point is located on the line according to the first distance, the second distance and the third distance.
After the second distance and the third distance are obtained, the distance range of each section on the line can be determined. For example, if the distance from point x to the line start point and the distance from point m to the line start point in fig. 2 are obtained, the range of the interval distance between point x and point m can be obtained. And if the distance from the point x to the starting point of the line is 10 kilometers, and the distance from the point m to the starting point of the line is 15 kilometers, determining that the line points which are 10 kilometers to 15 kilometers away from the starting point of the line are all located in the range of the interval distance from x to m. Therefore, comparing the first distance with the second distance and the third distance, respectively, the target section in which the target point is located can be determined. The number of segments on a line may be determined by the number of segments and the number of long chains, for example, if a segment is divided in the middle of a line and there is no long chain, the number of segments on the line is three, the portion before the start point of the segment is one segment, and the portion after the end point of the segment is one segment.
In this embodiment, optionally, determining a target interval where the target point is located on the line according to the first distance, the second distance, and the third distance includes: comparing the first distance with the second distance to obtain a minimum second distance which is greater than the first distance and a maximum second distance which is less than the first distance; determining a target segment where the target point is located according to the segment boundary points corresponding to the minimum second distance and the maximum second distance; and comparing the first distance with the third distance in the target segment, and determining a target interval of the target point in the target segment according to the comparison result.
Specifically, the first distance and the second distance are compared, and the second distance can be used to divide the segments on the line. The second distance smaller and closest than the first distance and the second distance larger and closest than the first distance are determined, i.e. the largest second distance smaller than the first distance and the smallest second distance larger than the first distance are determined. The line point associated with the maximum second distance is a segment starting point in the segment boundary points, the line point associated with the minimum second distance is a segment ending point in the segment boundary points, and the line between the segment starting point and the segment ending point is the target segment. The target point is located within the target segment and therefore only a third distance within the target segment needs to be determined. The first distance is compared to a third distance within the target segment to determine a target interval for the target point in the target segment. For example, if the first distance is smaller than any third distance in the target segment, determining that the target interval is an interval between the segment start point and the first long-chain start point; if the first distance is greater than any third distance in the target segment, determining that the target interval is an interval between the segment end point and the last long-chain end point; and if the first distance is between the two third distances, determining that the target interval is the interval between the long-chain boundary points associated with the two third distances. The beneficial effect who sets up like this lies in, confirms the target segmentation earlier and confirms the target interval again, can filter the third distance, reduces the calculated amount, avoids data too much to cause the confusion, improves the definite precision of target interval.
In this embodiment, optionally, determining a target interval where the target point is located on the line according to the first distance, the second distance, and the third distance includes: sorting the first distance, the fifth distance, the sixth distance, the seventh distance and the eighth distance in size; taking line boundary points associated with adjacent distances arranged before and after the first distance as a first interval point and a second interval point, and determining an interval between the first interval point and the second interval point as a target interval; the line boundary points comprise segment boundary points and long-chain boundary points.
Specifically, after determining the fifth distance and the sixth distance in the second distances and the seventh distance and the eighth distance in the third distances, the first distance, the fifth distance, the sixth distance, the seventh distance, and the eighth distance are sorted according to the size of the distance value. The adjacent distance is a distance value adjacent to the first distance arrangement order among the fifth distance, the sixth distance, the seventh distance, or the eighth distance. And obtaining adjacent distances arranged before the first distance and adjacent distances arranged after the first distance according to the arrangement sequence, and determining line boundary points associated with the adjacent distances, wherein the associated line boundary points are segment boundary points or long-chain boundary points and do not include line starting points. And taking the associated line boundary point of the adjacent distance before the first distance as a first interval point, taking the associated line boundary point of the adjacent distance after the first distance as a second interval point, and taking the line between the first interval point and the second interval point as a target interval. The beneficial effects of setting up like this lie in, need not carry out the confirming of target interval step by step, obtain the target interval fast through the range sorting, improve the confirming efficiency of target interval, and then improve parameter and acquire efficiency.
And 140, determining target parameters of the target point according to the interval starting point parameters and the first distance of the target interval.
After the target interval is obtained, an interval starting point parameter and an interval end point parameter of the target interval are determined, the interval starting point and the interval end point are respectively a first interval point and a second interval point, the interval starting point parameter and the interval end point parameter are configuration information of corresponding segment boundary points or long-chain boundary points, the configuration information can be mileages of line points, and the segment boundary points and the long-chain boundary points belong to the line points. The distance between the section start point and the route start point can be determined from the section start point parameter, and the distance between the target point and the section start point can be determined from the first distance. The interval starting point is a long-chain boundary point or a segment boundary point. Because the parameter marks of the starting point and the end point of the interval are the same, linear calculation is directly carried out according to the distance between the target point and the starting point of the interval and based on the parameters of the starting point of the interval, and the target parameters of the target point can be obtained through conjecture. For example, if the starting point of the interval is a long-chain starting point 20-2, and the distance between the target point and the starting point of the interval is 1 km, it may be determined that the target parameter of the target point is 20-3, and the distance between the milestones of every two line points is preset.
And 150, comparing the target parameters with the known parameters of the target point, and if the target parameters are consistent with the known parameters of the target point, determining that the known distance and the target parameters are successfully obtained.
After the target parameters are obtained, in order to determine whether the obtained target parameters and the pre-calculated known distance are accurate, the known parameters of the target point used when the known distance is calculated are obtained. The known parameters of the target point are conditions for calculating the known distance and are not used in calculating the target parameters. The known parameters are correct parameters of the target points, the target parameters are compared with the known parameters, if the target parameters are consistent with the known parameters, the target parameters are correct, the known distance of the target parameters is calculated to be correct, the known distance and the target parameters are tested successfully, the parameter test of the line points is completed, and the parameter test of the line points can include the test of the known distance and the target parameters.
When controlling the travel of a train, it is necessary to determine a braking curve of the train from the train travel distance, and in order to ensure the accuracy of the train route travel distance, the distance is calculated and then recalculated for confirmation. However, in the process of recalculation, manpower and time are wasted, so that the calculated distance can be adopted to perform reverse-deduction on the parameters on the line points, and the accuracy of distance calculation is determined according to the reverse-deduction on of the parameters.
According to the technical scheme of the embodiment, the reverse deduction of the distance is realized through the input point parameters and the distance data between the target point and the input point, and the line parameters of the target point are obtained. The distance between each interval point on the line and the starting point of the line can be obtained according to the preset configuration information of the line, and the target interval where the target point is located is determined, wherein the interval point can be a segment boundary point or a long-chain boundary point. And obtaining target parameters according to the starting point and the end point parameters of the target interval, and if the target parameters are consistent with the known parameters, the calculation of the known distance is also correct when the target parameters are correct. The method solves the problem that the target point parameter can not be obtained by direct reverse-thrust in the prior art, avoids the process of re-determining the distance between the target point and the input point by forward calculation, realizes the reverse-thrust of the target point parameter by the most basic known information, ensures the correctness of the known distance and the target point parameter, saves manpower and time, reduces the calculated amount, and ensures that the test efficiency of the line parameter is improved.
Example two
Fig. 3 is a flowchart illustrating a method for acquiring parameters of a route point according to a second embodiment of the present invention, where the method is further optimized based on the second embodiment. As shown in fig. 3, the method specifically includes the following steps:
And step 320, determining a second distance between the section boundary and the line starting point and a third distance between the long-chain boundary and the line starting point according to the configuration information of the section boundary and the long-chain boundary on the line.
And step 330, determining a target interval where the target point is located on the line according to the first distance, the second distance and the third distance.
And 340, determining target parameters of the target point according to the interval starting point parameters and the first distance of the target interval.
And step 350, comparing the target parameters of the target point with preset parameters configured on the line, and determining whether the preset parameters contain the target parameters.
After the target parameter is obtained, whether the target parameter is legal or not is determined. And comparing the target parameter with a preset parameter configured on the line, wherein the preset parameter configured on the line is configuration information of each line point on the line, and can be a milestone of each line point on the line, for example. And comparing the target parameters with preset parameters configured on the line to determine whether the preset parameters have the target parameters. If the target parameter exists, the target parameter is legal, the target parameter can be compared with the known parameter, and the backward test of the line point parameter is completed.
And step 360, if the target parameters do not exist, determining that the target parameters are illegal, and sending prompt information.
If the preset parameters do not include the target parameters, the target parameters are illegal, errors occur in the calculation process, and the known distance cannot be confirmed according to the target parameters. For example, the mileage mark of the long chain boundary point in the preset parameters is 20-9 at the maximum, and the calculated target parameter is 20-10, the target parameter is illegal. And prompt information can be sent to remind the staff to carry out the re-backward thrust, so that the calculation of the known distance is correct. If the target parameter is illegal, the calculation is wrong, the target parameter is compared with the known parameter, and the comparison result is that the target parameter and the known parameter are not consistent. Therefore, after the target parameter is determined to be illegal, the target parameter is directly retested, and the testing efficiency is improved.
According to the embodiment of the invention, the reverse thrust of the distance is realized through the data of the input points and the distance data between the target point and the input points, and the line parameters of the target point are obtained. The distance between each interval point on the line and the starting point of the line can be obtained according to preset configuration information of the line, the target interval where the target point is located is determined, and the target parameter is obtained according to the starting point and the end point parameters of the target interval. And confirming whether the target parameters are legal or not after the target parameters are obtained, and if the target parameters are illegal, confirming again. The method avoids comparing illegal target parameters with known parameters, and improves the confirmation precision and efficiency. The method solves the problem that the target point parameter can not be obtained by direct reverse-estimation in the prior art, avoids the process of re-determining the distance between the target point and the input point by forward calculation, realizes the reverse-estimation of the target point parameter through the most basic known information, ensures the correctness of the known distance and the target point parameter, saves manpower and time, reduces the calculated amount, and ensures the improvement of the test efficiency of the line parameter.
