Description
Technical Field
The invention relates to the related field of railway traffic management, in particular to a method and a system for filing the position precision of a speed-limiting area of a train control system of a passenger special line.
Background
China railway CTCS-2(China Train Control System) level Train Control System controls the Train operation in a point-to-point mode. Point or spot transponders, or continuous track circuits. The function of the transponder is to provide key vehicle control information to the train-mounted equipment, such as information packets of line entering speed, line gradient, track section, temporary speed limit and the like, and the information packets are combined and encoded, and are called transponder messages. The transponder messages are divided into active messages and passive messages. Active messages are compiled by the train control centre and sent to the transponder via the LEU (ground electronic unit) and finally transmitted to the train. L _ TSRarea, D _ TSR (n) and L _ TSR (n) are variables representing length or distance, and the number of bits occupied by the variables in the message is 15 bits, so that the value range is 0-32767. L _ TSRarea is equal to the sum of all D _ TSRs and all L _ TSRs, so the value of L _ TSRarea is the largest among all variables representing length or distance. The length L _ TSRarea of the valid section of the temporary speed limit information determines the resolution of the distance/length. When the length of the temporary speed-limiting effective section does not exceed 32767m, Q _ SCALE takes 1 to indicate that the distance/length resolution is 1 m; when the length of the temporary speed-limiting effective section exceeds 32767m, Q _ SCALE takes 2, and the distance/length resolution is 10 m. When the distance/length resolution is 10m, if the values of variables such as L _ TSRarea, D _ tsr (n), L _ tsr (n), etc. are not integer multiples of 10, it is necessary to archive them with 10m precision. In order to ensure the driving safety, after the 10m precision filing is required to be ensured, the speed limit value at any position cannot be increased. This generally results in an extension of the temporary speed limit active section. However, if the effective length (L _ TSRarea) of the temporary speed limit information is extended too much, the driving efficiency is affected. When 10m precision is filed, how to ensure the driving safety without influencing the operation efficiency as much as possible becomes an urgent problem to be solved.

Summary of the application
China railway CTCS-2(China Train Control System) level Train Control System controls the Train operation in a point-to-point mode. Point or spot transponders, or continuous track circuits. The function of the transponder is to provide key vehicle control information to the train-mounted equipment, such as information packets of line entering speed, line gradient, track section, temporary speed limit and the like, and the information packets are combined and encoded, and are called transponder messages. The transponder messages are divided into active messages and passive messages. Active messages are compiled by the train control centre and sent to the transponder via the LEU (ground electronic unit) and finally transmitted to the train. L _ TSRarea, D _ TSR (n) and L _ TSR (n) are variables representing length or distance, and the number of bits occupied by the variables in the message is 15 bits, so that the value range is 0-32767. L _ TSRarea is equal to the sum of all D _ TSRs and all L _ TSRs, so the value of L _ TSRarea is the largest among all variables representing length or distance. The length L _ TSRarea of the valid section of the temporary speed limit information determines the resolution of the distance/length. When the length of the temporary speed-limiting effective section does not exceed 32767m, Q _ SCALE takes 1 to indicate that the distance/length resolution is 1 m; when the length of the temporary speed-limiting effective section exceeds 32767m, Q _ SCALE takes 2, and the distance/length resolution is 10 m. When the distance/length resolution is 10m, if the values of variables such as L _ TSRarea, D _ tsr (n), L _ tsr (n), etc. are not integer multiples of 10, it is necessary to archive them with 10m precision. In order to ensure the driving safety, after the 10m precision filing is required to be ensured, the speed limit value at any position cannot be increased. This generally results in an extension of the temporary speed limit active section. However, if the effective length (L _ TSRarea) of the temporary speed limit information is extended too much, the driving efficiency is affected. When 10m precision is filed, how to ensure the driving safety without influencing the operation efficiency as much as possible becomes an urgent problem to be solved.
In view of the above technical problems, the technical solution provided by the present application has the following general idea:
the embodiment of the application provides a method for filing position precision of a speed limit area of a passenger dedicated line train control system, wherein the method comprises the following steps: obtaining first distance data; sorting the first distance data based on a first preset rule to obtain a first sorting result; obtaining a first filing instruction, and filing the position of the first sequencing result according to the first filing instruction to obtain a first filing result; obtaining a first processing instruction, and processing the first archiving result according to the first processing instruction to obtain a first processing result; and obtaining a second preset rule, calculating the first processing result based on the second preset rule, obtaining a first temporary speed-limiting section distance and a first temporary speed-limiting section length, and filing the position accuracy of the speed-limiting section based on the first temporary speed-limiting section distance and the first temporary speed-limiting section length.
Having thus described the general principles of the present application, various non-limiting embodiments thereof will now be described in detail with reference to the accompanying drawings.
Example one
As shown in fig. 1, an embodiment of the present application provides a method for filing the position accuracy of a speed-limit zone of a train control system of a passenger dedicated line, where the method includes:
step S100: obtaining first distance data;
further, as shown in fig. 2, step S100 in the embodiment of the present application further includes:
step S110: obtaining transponder location information;
step S120: acquiring the starting position information and the end position information of the speed limit area;
step S130: and acquiring the first distance data according to the position information of the responder and the position information of the starting point of the speed limit area.
Step S200: sorting the first distance data and the second distance data based on a first preset rule to obtain a first sorting result;
specifically, in the process of processing the speed limit, it is known that the starting point of the temporary speed limit zone TSR is TSR- > start, the end point TSR- > end of the temporary speed limit zone TSR, and the speed limit value TSR- > v of the temporary speed limit zone, the position of the positive line active transponder is bls _ pos, and the length of the active section of the positive line active transponder TSR is l _ tsrarea. To facilitate the following description, first 3 functions are defined: defining the ceiling function as ceiling () whose role is to round up fractional numbers, for example: ceiling (3.4) =4, ceiling (3) = 3. The floor function is defined as floor (), whose effect is to round down fractions, for example: floor (5.6) =5, floor (5) = 5. An absolute value function abs () is defined, whose effect is to take the absolute value, for example: abs (-1) =1, abs (5) = 5. And obtaining the position information of the transponder under the same coordinate system, wherein the transponder is a positive line active transponder and is represented by bls _ pos. Acquiring starting point position information and end point position information of a speed-limiting area under the same coordinate system, wherein the starting point position of the speed-limiting area is represented by tsr- > start, the end point position of the speed-limiting area is represented by tsr- > end, and the distance between the starting point of each section of the speed-limiting area and a transponder is calculated, namely the first distance data: tsr (n) - > d _ bls2start = abs (tsr (n) - > start-bls _ pos), and the distance between the start point and the end point of each speed-limit zone is calculated, that is, the second data: tsr (n) - > d _ bls2end = abs (tsr- > start-tsr- > end). For example, assume now that a scene, the coordinate bls _ pos of the transponder is 0, and the effective length of the positive temporary speed-limiting section is 40000 m. Setting three stages of speed limit: the coordinate of the starting point of the first section of speed limit is 20001m, the coordinate of the terminal point is 21001m, and the speed limit value is 9; the coordinate of the starting point of the second section of speed limit is 21003m, the coordinate of the terminal point is 21009m, and the speed limit value is 15; the coordinate of the starting point of the third speed limit is 21013m, the coordinate of the end point is 39897m, and the speed limit value is 16. In addition, a 100m long speed limit is fixedly arranged at the inner side of the tail end of the temporary speed limit effective section, the starting point of the speed limit is 39900, the end point of the speed limit is 40000, and the speed limit value is 9. Since the effective length of the temporary speed-limiting section exceeds 32767m, the distance/length resolution needs to be set to 10m, and the speed-limiting area needs to be accurately archived. Variables are defined according to known information: bls _ pos =0, | tsrarea =40000, tsr (1) - > start =20001, tsr (1) - > end =20003, tsr (1) - > v =9, tsr (2) - > start =21001, tsr (2) - > start =21003, tsr (2) - > end =21009, tsr (2) - > v =15, tsr (3) - > start =21013, tsr (3) - > end =39897, tsr (3) - > v =16, tsr (4) - > start =39900, tsr (4) - > end =40000, tsr (4) - > v = 9. The distance between the start of the speed limit of each segment and the transponder is calculated as tsr (1) - > d _ bls2start =20001, tsr (2) - > d _ bls2start =21003, tsr (3) - > d _ bls2start =21013, and tsr (4) - > d _ bls2start = 39900. And calculating the distance between each section of the speed limit end point and the transponder, wherein tsr (1) - > d _ bls2end =21001, tsr (2) - > d _ bls2end =21009, tsr (3) - > d _ bls2end =39897, and tsr (4) - > d _ bls2end = 40000. The first predetermined rule is a small-to-large ordering rule, and all tsrs are ordered from small to large according to tsr (n) - > d _ bls2start, and as shown in the above example, the ordering result is tsr (1), tsr (2), tsr (3) and tsr (4).
Step S300: obtaining a first filing instruction, and filing the position of the first sequencing result according to the first filing instruction to obtain a first filing result;
specifically, the first archiving instruction is an instruction to archive the starting point and the ending point of each speed limit tsr (n) in the first distance data and the second distance data, where the archiving starting point is: tsr (n) = bls _ pos + floor (tsr (n) — > d _ bls2start/10) × 10; the filing end point is tsr (n) - > end = bls _ pos + ceiling (tsr (n) - > d _ bls2end/10) × 10. As in the above example, the archive result obtained based on the archive start point and the archive end point is: tsr (1) - > start '= 20000, tsr (1) - > end' =21010, tsr (2) - > start '= 21000, tsr (2) - > end' =21010, tsr (3) - > start '= 21010, tsr (3) - > end' =39900, tsr (4) - > start '= 39900, tsr (4) - > end' = 40000.
Step S400: obtaining a first processing instruction, and processing the first archiving result according to the first processing instruction to obtain a first processing result;
step S500: and obtaining a second preset rule, calculating the first processing result based on the second preset rule, obtaining a first temporary speed-limiting section distance and a first temporary speed-limiting section length, and filing the position accuracy of the speed-limiting section based on the first temporary speed-limiting section distance and the first temporary speed-limiting section length.
Specifically, the first processing instruction is a process of further processing the archived result after the archiving processing, and the process includes, but is not limited to, processing of an overlapping section and removing of the length of the speed limit, where the processing of the overlapping section refers to, by starting analysis on the second speed limit, when tsr (n) -start '< tsr (n-1) - > end' of the speed limit, determining that the overlapping section exists, and processing the overlapping section based on a predetermined rule; and the elimination of the speed limit length is carried out based on the numerical comparison result of the filing starting point and the filing end point of tsr (n) of each speed limit length. And obtaining the first processing result according to the processing result and the eliminating result of the overlapping section. The second preset rule is a rule which carries out different calculations according to different values of n of tsr (n), when n is 1, the distance of the first temporary speed limit section is the distance/10 from the archived speed limit starting point to the responder, and when n is not 1, the distance of the first temporary speed limit section is the distance/10 from the archived speed limit starting point to the speed limit end point of the previous section. The length of the first temporary speed limit section is 10 of the distance from the starting point to the end point after the filing of each speed limit. And performing position precision filing of the speed-limiting zone based on the distance of the first temporary speed-limiting zone and the length of the first temporary speed-limiting zone, so that the position precision filing is performed when multiple sections of speed-limiting zones with too short distance are processed, namely the safety can be ensured, and the driving efficiency can be ensured.
Further, as shown in fig. 3, step S400 in the embodiment of the present application further includes:
step S410: obtaining n pieces of speed limit information according to the first filing result, wherein each of the n pieces of speed limit information comprises a filing starting point and a filing end point, and n is a positive integer greater than 2;
step S420: obtaining a first overlapping area processing instruction, carrying out size judgment on an mth filing starting point and an mth-1 filing end point of the n pieces of speed limit information according to the first overlapping area processing instruction, and obtaining a first judgment instruction when a judgment result meets a first requirement, wherein m is a positive integer less than or equal to n;
step S430: comparing the values of the mth speed limit information and the mth-1 speed limit information according to the first judgment instruction to obtain a first comparison result;
step S440: when the first comparison result meets a second requirement, adjusting the (m-1) th archiving end point to 10;
step S450: when the first comparison result does not meet the second requirement, adjusting the mth archiving start point to 10;
step S460: and obtaining the first processing result according to the adjustment result.
Specifically, n pieces of speed limit information are obtained according to the first filing result, wherein n is a positive integer greater than 2, the speed limit information after being processed by the filing starting point and the filing end point is collected and obtained, and the n pieces of speed limit information are obtained, wherein each of the n pieces of speed limit information includes the filing starting point and the filing end point. The first overlap area processing instruction is a control instruction for processing an overlap area, the overlap area processing is performed based on the first overlap area processing instruction, the overlap area processing procedure is as follows, the size judgment of the mth filing starting point and the mth-1 filing end point is performed on the n pieces of speed limit information according to the first overlap area processing instruction, wherein m is a positive integer which is larger than 1 and smaller than or equal to n, namely, the overlap area judgment is performed from the second speed limit, the first requirement is that the mth filing starting point is smaller than the mth-1 filing end point, when the relation exists, the processing of the overlap area is continued, otherwise, the processing of the overlap area is not performed on the speed limit information. When the mth filing starting point and the mth-1 filing end point are judged to meet the first requirement, a first judgment instruction is obtained, the numerical value of the mth speed limit information and the mth-1 speed limit information are compared based on the first judgment instruction to obtain a first comparison result, when the first comparison result is that the mth speed limit information is smaller than the mth-1 speed limit information, the first comparison result meets a second requirement, the mth-1 filing end point is adjusted to have a numerical value of 10, when the first comparison result does not meet the second requirement, the mth filing starting point is adjusted to have a numerical value of 10, and the first processing result is obtained according to the adjustment result of the filing starting point or the filing end point. As exemplified above, the overlap interval processing is performed, tsr (2) - > start ' < tsr (1) - > end ', and tsr (2) - > v > tsr (1) - > v, so that tsr (2) - > start ' is adjusted to 21010.
Further, as shown in fig. 4, step S400 in the embodiment of the present application further includes:
step S470: comparing the filing starting point and the filing end point of each piece of speed limit information to the n pieces of speed limit information to obtain a second comparison result;
step S480: and when the mth filing starting point in the second comparison result is equal to the mth filing end point, eliminating the mth speed limiting information, and obtaining the first processing result based on the elimination result.
Specifically, the process of comparing the filing starting point and the filing end point of each piece of speed limit information is a process of eliminating 0-long speed limit, the numerical value of the filing starting point and the filing end point of each piece of speed limit information is compared with the numerical value of the filing starting point and the filing end point of each piece of speed limit information, that is, tsr (n) -start 'and tsr (n) -end' of each piece of speed limit are compared to obtain the second comparison result, when the mth filing starting point in the second comparison result is equal to the mth filing end point, the mth speed limit information is eliminated, that is, any one filing starting point in the n pieces of speed limit information is equal to the filing end point, the piece of speed limit information is eliminated, and the first processing result is obtained based on the elimination result. As described above, the 0-long speed limit information is rejected as tsr (2) - > start '= tsr (2) - > end', and therefore, tsr (2) is rejected.
Further, as shown in fig. 5, step S500 in the embodiment of the present application further includes:
step S510: obtaining the ith speed limit information in the n pieces of speed limit information, wherein i is a positive integer less than or equal to n;
step S520: judging whether the ith speed limit information is first speed limit information or not;

Further, step S520 in the embodiment of the present application further includes:
step S521: and when the ith speed limit information is not the first speed limit information, obtaining the distance of the temporary speed limit section according to the ith filing starting point and the ith-1 filing end point in the ith speed limit information.
Specifically, in the process of calculating the temporary speed limit section distance (D _ TSR), it is necessary to perform separate calculation after judgment according to the position relationship of the speed limit information, to obtain any one of the n pieces of speed limit information, which is denoted as ith speed limit information, where i is a positive integer less than or equal to n, to judge whether the obtained ith speed limit information is first speed limit information, and when the ith speed limit information is first speed limit information, calculate the temporary speed limit section distance according to the distance from a first filing starting point corresponding to the first speed limit information in the first processing result to the responder position information, that is, if i = 1: d _ TSR (i) = (tsr (i))>start' -bls _ pos)/10. When the ith speed limit information is not the first speed limit information, obtaining the temporary speed limit section distance according to the ith filing starting point and the ith-1 filing end point in the ith speed limit information, namely if the ith speed limit information is not the first speed limit information

Further, step S500 in the embodiment of the present application further includes:
step S540: and obtaining the length of the first temporary speed limit section according to the distance between the pth archiving start point and the pth archiving end point in the n pieces of speed limit information, wherein p is a positive integer less than or equal to n.
Specifically, the first temporary speed limit section length (L _ TSR) is calculated from the filing start point and the filing end point of each piece of speed limit information, i.e., L _ TSR (p) = (TSR (p) -end '-TSR (p) - > start')/10. As in the above example, D _ TSR (1) =2000, L _ TSR (1) =1, D _ TSR (2) =0, L _ TSR (2) =1889, D _ TSR (3) =0, L _ TSR (3) =10 can be calculated. L _ TSRarea is equal to L _ TSRarea divided by 10 and rounded up, i.e. L _ TSRarea = 4000.
