Description

Technical Field

[0001] The present invention relates to the technical field of track slab design and laying, and in particular to a track slab intelligent matching method and system. Background Art

[0002] In the process of track slab design and laying of ballastless track, the reasonable calculation and selection of track slab laying combination and spacing is the key factor to ensure the optimal and economical track engineering technology, and also the key to ensure track stability and safety. Traditional track slab calculation methods mainly include trial calculation or exhaustive method, but the existing methods are inefficient, the slab scheme is not optimized, there are certain errors, and more importantly, there is no optimization calculation for special slab types. When there are special slab types in the track slab, it is impossible to prepare a slab scheme.

[0003] With the development of technology, automated and intelligent track slab laying technology has gradually become a research hotspot. Rapid calculation and optimization of ballastless track layout design schemes and construction control data is the basis for improving automation, intelligence and digitalization. It is necessary to develop a track slab design and laying method suitable for ballastless track. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems of low calculation efficiency and large calculation error at the beam joints in bridge sections in the track slab matching of the prior art ballastless track, and to provide a track slab intelligent matching method and system. The method and system can automatically calculate and optimize the laying combination of the track slabs, thereby improving the laying efficiency and accuracy.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] A method for intelligently matching track slabs comprises the following steps:

[0007] Step S1, obtaining the length l of the track section where the track slab needs to be laid, an array of track slab lengths sorted in order of use, a standard slab seam width, and a slab seam deviation;

[0008] Step S2: Determine the track segment length l and the general track segment length l N The size of l, if l≤l N , the length of the track to be matched is l0, then l0=l; if l>l N First, the standard track plate in the track plate length array is used to match the track section length l, so that the remaining track section length is closest to l. N But not greater than l N , take the remaining track section length as the track length l0 to be matched;

[0009] Step S3, determining the search range of the number of track plates in the track length matching, matching the track length to be matched according to the track plate length array, the standard plate seam width and the plate seam deviation, and obtaining the matching scheme for the track length to be matched;

[0010] Step S4, if l≤l N , the plate matching scheme of the track length to be matched is used as the plate matching scheme of the track section; if l>l N , the standard track plate matching scheme used in step S2 is combined with the matching scheme of the track length to be matched, and the matching scheme of the track section is obtained.

[0011] In the technical solution of the present invention, the parameters of the plate matching are first obtained, including the track section length l, the track plate length array, the standard plate seam width and the plate seam deviation, wherein the track plate lengths in the track plate length array are arranged in the order of most commonly used to least commonly used. Then, the track length to be matched is calculated, and the search range of the number of track plates in the plate matching is determined. In the subsequent plate matching process, the number of track plates is within the minimum and maximum range of the search range, which can reduce the amount of calculation. Then, according to the track plate length array, the standard plate seam width and the plate seam deviation, the track length to be matched is matched to obtain a plate matching scheme, and finally the plate matching scheme for the track section is obtained.

[0012] Through the above technical solution, according to different track section lengths and track plate types, it is also possible to customize track plates of any length or configure any number of track plate parameters, flexibly adjust the laying plan to match the plates, and calculate the optimal laying combination of the track plates. If you want to adjust the priority of different track plates in the laying plan, you can directly adjust the order in the track plate length array, thereby improving the efficiency and freedom of track plate configuration. The present invention can effectively perform intelligent matching of track sections, ensure the rationality and economy of track plate laying, accurately calculate the laying combination of track plates, and improve the accuracy of track plate configuration.

[0013] The track slab length array is composed of all the track slabs that can be used in the process of laying the track section, and is sorted according to the order of use in the process of laying the track slabs, and the length data of the track slabs are combined to form an array; the standard slab joint width is the slab joint width between the track slabs determined according to relevant specifications; the slab joint deviation includes the negative slab joint deviation and the positive slab joint deviation.

[0014] The universal track section length refers to the track section that can be successfully equipped with any type of standard track slabs regardless of the type of standard track slabs used. In engineering applications, it can be determined based on experience or calculated based on the different types of standard track slabs available.

[0015] As a preferred solution of the present invention, in step S1, the acquired data also includes the maximum allowable value of the fastener spacing. For different track plates, the distance from the end fastener to the plate end is different. The distance from the end fastener to the plate end is determined according to the type of the end track plate, and then the track plate position and the specific plate seam width are calculated and determined by the maximum allowable value of the fastener spacing, so as to achieve the purpose of improving the track plate layout accuracy at the bridge beam seam.

[0016] As a preferred embodiment of the present invention, the track plate includes at least one standard track plate and zero to multiple special-shaped track plates. The standard track plate refers to a commonly used track plate with uniform size and shape that meets the laying standard requirements and is used for laying regular parts of straight tracks or curved tracks; the special-shaped track plate is a track plate of special shape or size designed to adapt to specific track layouts or structural requirements.

[0017] As a preferred embodiment of the present invention, different track plate lengths are arranged in a track plate length array in a certain order, and the sorting method adopted is: when the track plate is a standard track plate, the track plate length array is sorted according to the utilization rates of different standard track plates; when the track plate includes standard track plates and special-shaped track plates, the standard track plates are arranged before the special-shaped track plates in the track plate length array, and for standard track plates, they are sorted according to the utilization rates of different standard track plates, and for special-shaped track plates, they are sorted according to the utilization rates of different special-shaped track plates.

[0018] As a preferred embodiment of the present invention, when l>l N When the length of the track to be matched is calculated as follows: the first standard track plate in the track plate length array is used to match the track section length l. After the first standard track plate is matched, the remaining track section length is the closest to l. N But not greater than l N , take the remaining track section length as the track length to be matched, l o The calculation formula is:

[0019]

[0020] Among them, slab_length_array[0] is the first element of the track plate length array, which is the most commonly used standard track plate length, and int() is the rounding function.

[0021] As a preferred solution of the present invention, the search range of the number of track plates is determined to be (x1, x2), x1 is the minimum value of the search range of the number of track plates, x2 is the maximum value of the search range of the number of track plates, and the calculation formulas of x1 and x2 are:

[0022]

[0023] Where slab_length_array is the track slab length array, max() is the maximum value function, min() is the minimum value function, and int() is the integer function.

[0024] As a preferred embodiment of the present invention, the specific steps of matching the length of the track to be matched are:

[0025] Step S311, select a track plate quantity i within the track plate quantity search range (x1, x2), match the track plates according to the track plate sequence in the track plate length array, and establish a track plate combination and a track plate length sum corresponding to the track length l0 to be matched;

[0026] Step S312, calculating the difference between the length l0 of the track to be matched and the sum of the lengths of the track plates of different track plate combinations, obtaining the remaining length, and calculating the deviation range of the track plate seam of different track plate combinations according to the plate seam deviation;

[0027] Step S313, judging whether the remaining length is within the deviation range of the track plate seam. If the remaining length is within the deviation range of the track plate seam, adding the track plate combination to the plate matching scheme; and continuing to search and adding all the track plate combinations that meet the conditions in the current track plate quantity i to the plate matching scheme;

[0028] Step S314, loop the number of track plates i in the track plate number search range (x1, x2), repeat steps S311 to S314, and obtain a track matching solution for the length of the track to be matched.

[0029] As a preferred solution of the present invention, a method for establishing a track plate combination corresponding to the track length l0 to be matched is as follows: according to the number of track plates i, the standard plate seam width and the track length l0 to be matched, different track plate lengths are selected from the track plate length array for matching, so that the total length of different track plate lengths after matching is close to the track length l0 to be matched, and all different track plate lengths that meet the conditions are used as a track plate combination.

[0030] As a preferred solution of the present invention, when more than one matching schemes for the length of the track to be matched are obtained, the optimal matching scheme is selected as the final matching scheme. The method for determining the optimal matching scheme is: sorting the number of track plates used in the matching schemes from most to least, and selecting the matching scheme that uses the least number of track plates and whose number of track plates used is sorted in the same order as the track plate length array as the optimal matching scheme.

[0031] As a preferred solution of the present invention, after step S314 is completed, if no matching solution for the track length l0 of the to-be-matched plates is found, then return to step S2, reduce the number of standard track plates, recalculate the track length of the to-be-matched plates, and repeat step S3 to obtain a matching solution for the track length l0 of the to-be-matched plates.

[0032] As a preferred solution of the present invention, when there is at least one input track plate length array that cannot meet the plate matching requirements of the track section length, the track section that cannot be matched with plates is regarded as a special section; all special section lengths are used as input conditions, and the special-shaped track plates are initialized at the same time. The track plate combinations of all special sections are calculated by a recursive search method to obtain possible plate matching solutions, and the Cartesian product of all plate matching solutions is generated to obtain a list of all special-shaped track plates that meet the special section plate matching solutions, and then the plate matching solution that uses the least type of special-shaped track plates is selected, and its special-shaped track plate combination is used as the best special-shaped track plate combination; then the best special-shaped track plate combination is added to the track plate length array, and steps S1 to S4 are repeated to perform plate matching calculations to obtain the plate matching solution for the track section that cannot be matched with plates. The above-mentioned solution can solve the problem that it is impossible to efficiently give a recommended special plate type solution when encountering a special track section length that cannot be matched with plates, and realize the plate matching of the track section that cannot be matched with plates.

[0033] Another aspect of the present invention provides a track slab intelligent matching system, the system comprising:

[0034] The data acquisition module is used to obtain the length l of the track section where the track slab needs to be laid, the track slab length array sorted in the order of use, the standard slab seam width and the slab seam deviation;

[0035] The first calculation module is used to determine the track segment length l and the general track segment length l N The size of l, if l≤l N , the length of the track to be matched is l0, then l0=l; if l>l N First, the standard track plate in the track plate length array is used to match the track section length l, so that the remaining track section length is closest to l. N But not greater than l N , take the remaining track section length as the track length l0 to be matched;

[0036] The second calculation module is used to determine the search range of the number of track plates in the track length matching to be matched;

[0037] The board matching module is used to match the board length of the track to be matched according to the track board length array, the standard board seam width and the board seam deviation, and obtain the board matching plan for the track length to be matched;

[0038] Output module, used if l≤l N , the plate matching scheme of the track length to be matched is used as the plate matching scheme of the track section; if l>l N , the standard track plate matching scheme used in step S2 is combined with the matching scheme of the track length to be matched, and the matching scheme of the track section is obtained.

[0039] The present invention also provides an electronic device, comprising at least one processor, a memory connected to the at least one processor for communication, and at least one input / output interface connected to the at least one processor for communication; the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the above-mentioned intelligent track plate matching method.

[0040] The present invention also provides a computer-readable storage medium, in which at least one instruction, at least one program, a code set or an instruction set is stored. The at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by a processor to implement the above-mentioned intelligent track plate matching method.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The present invention provides an intelligent plate matching method. According to different track section lengths and track plate types, track plates of any length can be customized or any number of standard track plate parameters can be configured. The laying plan can be flexibly adjusted to match the plates, and the optimal laying combination of the track plates can be calculated. If the priority of different track plates in the laying plan is to be adjusted, the order in the track plate length array can be directly adjusted, which improves the efficiency and freedom of track plate configuration, can effectively perform intelligent plate matching on the track section, ensure the rationality and economy of track plate laying, can accurately calculate the laying combination of the track plates, and improve the track plate configuration accuracy with high accuracy.

[0058] Example 1

[0059] This embodiment provides a track plate intelligent matching method, such as Figure 1 As shown, the following steps are included:

[0060] Step S1, obtaining the length l of the track section where the track slab needs to be laid, the track slab length array slab_length_array sorted in order of use, the standard slab gap width standard_gap, the slab gap deviation, and the maximum allowable fastener spacing value max_fastening_space;

[0061] The track slab length array is composed of all the track slabs that can be used in the process of laying the track section, and is sorted in the order of use in the process of laying the track slabs, and the length data of the track slabs are combined to form an array; the standard slab gap width is the slab gap width between the track slabs determined according to relevant specifications; the slab gap deviation includes the negative slab gap deviation gap_negative_deviation and the positive slab gap deviation gap_positive_deviation. Among the obtained parameters, the maximum allowable fastener spacing value is in mm, and all other length units are in m.

[0062] In some embodiments, the track plates include zero to multiple special-shaped track plates. Standard track plates refer to commonly used track plates with uniform size and shape that meet the laying standard requirements and are used for laying regular parts of straight tracks or curved tracks. Special-shaped track plates are track plates of special shapes or sizes designed to adapt to specific track layouts or structural requirements. When the track plates are standard track plates, the track plate length array is sorted according to the utilization rates of different standard track plates. When the track plates include standard track plates and special-shaped track plates, the standard track plates are arranged before the special-shaped track plates in the track plate length array. For standard track plates, they are sorted according to the utilization rates of different standard track plates. For special-shaped track plates, they are sorted according to the utilization rates of different special-shaped track plates.

[0063] Step S2: Determine the track segment length l and the general track segment length l N The size of l, if l≤l N, the length of the track to be matched is l0, then l0=l; if l>l N First, the standard track plate in the track plate length array is used to match the track section length l, so that the remaining track section length is closest to l. N But not greater than l N , and take the remaining track section length as the track length l0 to be matched.

[0064] When l>l N When the length of the track to be matched is calculated as follows: the first standard track plate in the track plate length array is used to match the track section length l. After the first standard track plate is matched, the remaining track section length is the closest to l. N But not greater than l N , take the remaining track section length as the track length to be matched, l o The calculation formula is:

[0065]

[0066] Among them, slab_length_array[0] is the first element of the track plate length array, which is the most commonly used standard track plate length, and int() is the rounding function.

[0067] Step S3, determine the search range of the number of track plates in the track length matching to be matched, match the track length to be matched according to the track plate length array, standard plate seam width and plate seam deviation, and obtain the track length matching plan to be matched.

[0068] The search range of the determined track plate quantity is (x1, x2), x1 is the minimum value of the track plate quantity search range, x2 is the maximum value of the track plate quantity search range, and the calculation formulas for x1 and x2 are:

[0069]

[0070] Where slab_length_array is the track slab length array, max() is the maximum value function, min() is the minimum value function, and int() is the integer function.

[0071] The length of the track to be matched is matched by a recursive search method. The matching solution is initialized before calculation. The specific steps are as follows:

[0072] Step S311, select a track plate quantity i within the track plate quantity search range (x1, x2), match the plates according to the track plate sequence in the track plate length array, and establish a track plate combination and track plate length and length_slabs corresponding to the track length l0 to be matched (adjust the plate seam and different order).

[0073] The method for establishing a track plate combination corresponding to the track length l0 to be matched is as follows: according to the number of track plates i, the standard plate seam width and the track length l0 to be matched, different track plate lengths are selected from the track plate length array for matching, so that the total length of different track plate lengths after matching is close to the track length l0 to be matched, and all different track plate lengths that meet the conditions are used as track plate combinations.

[0074] Step S312, calculate the difference between the length l0 of the track to be matched and the sum of the lengths of the track plates of different track plate combinations to obtain the remaining length length_remain, and calculate the track plate seam deviation range of the track plate combinations of different track plate combinations according to the plate seam deviation.

[0075] Step S313, judging whether the remaining length length_remain is within the track plate seam deviation range, if the remaining length length_remain is within the track plate seam deviation range, adding the track plate combination to the plate matching solution; if length_remain is within the given track plate seam deviation range, indicating that a valid track plate combination is found, the combination is added to the plate matching solution; if not, indicating that the track plate combination cannot be matched to the track length to be matched, the track plate combination is abandoned;

[0076] And continue searching to add all the track plate combinations that meet the conditions in the current track plate quantity i to the plate matching solution. Step S314, loop the track plate quantity i in the track plate quantity search range (x1, x2), repeat steps S311 to S314, and obtain the plate matching solution for the track length to be matched. When more than one matching scheme for the track length to be matched is obtained, select the optimal matching scheme as the final matching scheme. The method for determining the optimal matching scheme is: sort the number of track plates used in the matching scheme from most to least, and select the matching scheme with the least number of track plates and the same order of the number of track plates used as the optimal matching scheme.

[0077] In some embodiments, after step S314 is completed, if no panel matching solution is found, that is, the panel matching solution returns null, indicating that no effective panel matching solution can be found for the current length l0 of the track to be matched. If l>l N , then return to step S2, reduce the number of standard track plates, recalculate the length of the track to be matched, and repeat step S3 to obtain a matching solution for the length of the track to be matched with l0; if l≤l N Or if a feasible plate matching solution still cannot be obtained after calculating all possible situations, the track section that cannot be matched with plates shall be treated as a special section, and the special-shaped track plates shall be calculated and added to the standard track plates for plate matching calculation.

[0078] In some embodiments, when there is at least one input track plate length array that cannot meet the plate matching requirements of the track section length, the track section that cannot be matched with plates is treated as a special section; all special section lengths are used as input conditions, and the special-shaped track plates are initialized at the same time. The initialized special-shaped track plates are determined manually according to specific circumstances, and the track plate combinations of all special sections are calculated by a recursive search method to obtain possible plate matching schemes, and the Cartesian product of all plate matching schemes is generated to obtain a list of all special-shaped track plates that meet the special section plate matching schemes, and then the plate matching scheme that uses the least type of special-shaped track plates is selected, and its special-shaped track plate combination is used as the best special-shaped track plate combination; then the best special-shaped track plate combination is added to the track plate length array slab_length_array, and steps S1 to S4 are repeated to perform plate matching calculations to obtain the plate matching scheme for the track section that cannot be matched with plates.

[0079] Step S4, if l≤l N , the plate matching scheme of the track length to be matched is used as the plate matching scheme of the track section; if l>l N , the standard track plate matching scheme used in step S2 is combined with the matching scheme of the track length to be matched, and the matching scheme of the track section is obtained.

[0106] Example 4
