[0002] The design of longitudinal and transverse joints of airport pavement is an important part of airport runway construction. The main purpose is to ensure the stability and durability of the runway when the aircraft takes off and lands and taxis. In order to control the location of cracks in the board and avoid excessive compressive stress caused by the expansion of the board, the surface layer of the airport flight area cement concrete pavement is usually cast in blocks with joints arranged between the boards.

[0003] At present, the joint design of cement concrete pavement in airport flight areas is generally carried out manually by professionals. However, the traditional manual design method is time-consuming and easily affected by human intervention, resulting in low design accuracy, which in turn affects the safety of airport pavement. Therefore, there is room for improvement. Summary of the invention

[0004] In order to improve the efficiency and accuracy of airport pavement joint design, the present application provides a method, system, equipment and medium for designing longitudinal and transverse joints of an airport pavement.

[0005] The above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0010] The seam spacing data is input into the joint template to automatically generate a design plan for the longitudinal and transverse joints of the airport pavement.

[0011] By adopting the above technical scheme, in the process of designing the longitudinal and transverse joints of the airport pavement, the basic data of the joints are obtained, the basic data type of the joints is obtained through the basic data of the joints, and the corresponding joint template is determined through the basic data type of the joints, so as to provide data support for the subsequent calculation of the spacing data of the seams and the automatic arrangement of the seams; by analyzing the area to be designed for the joints, the regional information is obtained, wherein the regional information includes the regional boundary, the reference line, the seam direction and the farthest distance from the reference line along the seam direction to the area to be designed for the joints; based on the regional information, a design base for the longitudinal and transverse joints of the airport is constructed, so as to provide geometric support for the subsequent automatic arrangement of the longitudinal and transverse joints; the area to be designed for the joints is divided into a plurality of seam spacing calculation intervals according to the regional information; different seam spacing calculation intervals adopt corresponding longitudinal and transverse joint design algorithms; the seam spacing data of the longitudinal and transverse joints of the airport pavement in the area to be designed for the joints are automatically calculated within the area to be designed for the joints; the obtained seam spacing data are input into the joint template; all the joint baselines are automatically arranged for the area to be designed for the airport pavement; the corresponding longitudinal and transverse joint design scheme for the airport pavement is generated, and the efficiency and accuracy of the airport pavement joint design are improved.

[0012] In a preferred example, the present application may be further configured as follows: the step of obtaining a plurality of seam spacing calculation intervals according to the region information specifically includes:

[0013] Acquire a sub-boundary of the region based on the region boundary, and acquire a distance from the reference line to the sub-boundary of the region based on the sub-boundary of the region and the reference line;

[0014] Integrate the distance from the reference line to the sub-boundary of the region and the sub-boundary of the region to form a boundary information set, generate a parallel boundary set based on a preset boundary information calculation rule, and determine whether the parallel boundary set is an empty set;

[0015] When the parallel boundary set is an empty set, determining whether the maximum distance in the parallel boundary set is equal to the farthest distance from the reference line along the seam direction to the seam design area to be joined, if not, determining that the seam spacing calculation interval is a non-parallel interval;

[0016] When the parallel boundary set is not an empty set, the seam spacing calculation interval is determined to be a standard interval or a local interval.

[0017] By adopting the above technical scheme, since the seam spacing scheme in the airport pavement longitudinal and transverse joint design area may be composed of multiple different seam spacing calculation intervals, wherein the seam spacing calculation interval includes a standard interval, a local interval and a non-parallel interval, by taking the regional sub-boundary and the distance from the reference line to the regional sub-boundary as a boundary information set, using the preset boundary information calculation rule, the parallel boundary combination is calculated, and it is determined whether the parallel boundary set is an empty set, and according to the judgment result, the airport pavement longitudinal and transverse joint design area is divided into corresponding seam spacing calculation interval types, so as to adopt corresponding seam spacing calculation schemes according to different seam spacing calculation intervals, thereby improving the accuracy of airport pavement joint design.

[0018] In a preferred example, the present application may be further configured as follows: generating a parallel boundary set based on a preset boundary information calculation rule and determining whether the parallel boundary set is an empty set specifically includes:

[0019] Acquire a regional sub-curve based on the regional boundary, determine whether the regional sub-curve is parallel to the reference line, and when the regional sub-curve is parallel to the reference line, acquire a direction and a distance from the reference line to the regional sub-curve;

[0020] Determine whether the direction of the reference line pointing to the regional sub-curve is the same as the direction of the cloth seam, and if so, determine whether the distance of the reference line pointing to the regional sub-curve is greater than a preset maximum seam spacing;

[0021] When the distance from the reference line to the regional sub-curve is greater than the preset maximum seam spacing, the distance from the reference line to the regional sub-curve and the regional sub-curve are input into the boundary information and combined to form a parallel boundary set.

[0022] In a preferred example, the present application can be further configured as follows: the obtaining of the seam spacing data based on the plurality of seam spacing calculation intervals and the preset longitudinal and transverse seam design algorithm specifically includes:

[0023] When the seam spacing calculation interval is a standard interval, generating a set of seam spacing arithmetic progressions based on a preset maximum seam spacing and a minimum seam spacing;

[0024] Generate a set of solutions for the seam spacing according to the arithmetic progression set of the seam spacing and the preset seam spacing constraint condition;

[0025] Determine whether the seam spacing solution set is an empty set; when the seam spacing solution set is not an empty set, determine minimum seam spacing solution data based on the seam spacing solution set; and output seam spacing data of a standard interval according to the minimum seam spacing solution data.

[0026] By adopting the above technical scheme, when the seam spacing calculation interval is a standard interval, a seam spacing arithmetic sequence set is generated for the standard interval according to the preset maximum seam spacing and minimum seam spacing, and multiple binary linear inequalities are constructed by using the seam spacing arithmetic sequence set and the preset seam spacing constraints. The seam spacing arithmetic sequence set is traversed to calculate a set of seam spacing solutions, and the minimum seam spacing solution data is selected from the seam spacing solution set. The seam spacing data of the standard interval is output according to the minimum seam spacing solution data, and then the seam arrangement spacing set within the standard interval is calculated, thereby realizing the automatic design of the seam spacing scheme for the standard interval.

[0027] In a preferred example, the present application can be further configured as follows: based on the plurality of the seam spacing calculation intervals and the preset longitudinal and transverse seam design algorithms, obtaining the seam spacing data, specifically also includes:

[0028] Obtaining the last baseline in the previous interval of calculating the distance between fabric seams, and using the last baseline in the previous interval of calculating the distance between fabric seams as a new reference line;

[0031] A binary linear inequality parameter set is constructed, the inequality parameter set is traversed based on a preset inequality index, inequality solution results are obtained according to a new seam spacing arithmetic progression set and seam spacing constraints, and seam spacing data is generated based on the inequality solution results.

[0032] By adopting the above technical solution, after completing the seam spacing data calculation for the previous seam spacing calculation interval, the last baseline in the previous seam spacing calculation interval is obtained and used as a new reference line, the parallel boundary set is updated using the new reference line, and it is determined whether the updated parallel boundary set is an empty set. When the updated parallel boundary set is not an empty set, it means that the seam spacing calculation interval is a local interval, and the last seam spacing data in the previous seam spacing calculation interval is obtained. The last seam spacing data in the previous seam spacing calculation interval will affect the seam spacing data of the local interval. According to the preset seam spacing constraint, the minimum seam spacing is updated using the last seam spacing data in the previous seam spacing calculation interval. The maximum seam spacing and the new minimum seam spacing are used to construct a new seam spacing arithmetic progression set. At the same time, a binary linear inequality parameter set is constructed, and the inequality parameter set is traversed using the preset inequality index. The inequality solution result is obtained through the new seam spacing arithmetic progression set and the seam spacing constraint condition, and the seam spacing data is generated according to the corresponding inequality solution result to realize the automatic design of the seam spacing scheme for the local interval.

[0033] In a preferred example, the present application can be further configured as follows: generating the seam spacing data based on the inequality solution result specifically includes:

[0034] The inequality solution results include solutions and no solutions. When the inequality solution result is no solution, it is determined whether the inequality parameter set has been traversed. If not, the inequality parameter set is continuously traversed until the inequality parameter set is traversed. If the inequality solution result is still no solution, a new maximum seam spacing is generated, and the seam spacing data calculation method of the standard interval is adopted with the new maximum seam spacing to generate the seam spacing data.

[0035] When the inequality solution is a solution, the seam spacing data of the local interval is output based on the inequality solution.

[0036] By adopting the above technical scheme, when the solution result of the inequality parameter set is no solution, it is determined whether the inequality parameter set has been traversed. If not, the inequality parameter set continues to be traversed according to the preset inequality index, and the inequality solution is solved in real time until the inequality parameter set is traversed. If the inequality solution result is still no solution, it means that the local interval range is small, then a new maximum seam spacing is generated, and the seam spacing data calculation method of the standard interval is adopted with the new maximum seam spacing to generate the seam spacing data within the interval. When the inequality solution result is a solution, the seam spacing data of the local interval is output according to the inequality solution, and then the seam arrangement spacing set within the local interval is calculated, so as to realize the automatic design of the seam spacing scheme for the local interval.

[0037] In a preferred example, the present application can be further configured as follows: based on the plurality of the seam spacing calculation intervals and the preset longitudinal and transverse seam design algorithms, obtaining the seam spacing data, specifically also includes:

[0038] When the seam spacing calculation interval is a non-parallel interval, obtaining the last baseline in the previous seam spacing calculation interval, determining whether the last baseline in the previous seam spacing calculation interval is zero, and when the last baseline in the previous seam spacing calculation interval is zero, using the maximum seam spacing as the seam spacing data;

[0039] When the last baseline in the previous seam spacing calculation interval is not zero, a remaining spacing set is obtained, and a remaining available seam distance is obtained based on the remaining spacing set;

[0040] Execute the following loop steps: "traverse the remaining spacing set based on a preset traversal index, and record the accumulated seam distance in real time, and determine whether the accumulated seam distance is less than or equal to the remaining seam distance;

[0041] If so, generate cloth seam spacing data, and input the cloth seam spacing data into the remaining spacing set to form a new remaining spacing set”

[0042] The above looping steps are stopped until the data in the new remaining spacing set is equal to the maximum seam spacing.

[0043] By adopting the above technical scheme, when the seam spacing calculation interval is a non-parallel interval, it is analyzed whether the last baseline in the previous seam spacing calculation interval is zero. When the last baseline in the previous seam spacing calculation interval is zero, the maximum seam spacing is used as the seam spacing data of the non-parallel interval, and the seam arrangement spacing set within the non-parallel interval is calculated; when the last baseline in the previous seam spacing calculation interval is not zero, the remaining spacing set is obtained, the remaining available seam distance is obtained through the remaining spacing set, the remaining spacing set is traversed according to the preset traversal index, and the cumulative seam distance is recorded in real time to determine whether the cumulative seam distance is less than or equal to the remaining available seam distance. When the cumulative seam distance is less than or equal to the remaining available seam distance, the corresponding seam spacing data is generated, and the seam spacing data is input into the remaining spacing set to form a new remaining spacing set, until the data in the new remaining spacing set is equal to the maximum seam spacing, then the seam spacing data of the interval is generated according to the new remaining spacing set, the seam arrangement spacing set within the non-parallel interval is calculated, and the automatic design of the seam spacing scheme for the non-parallel interval is realized.

[0075] Specifically, refer to Figure 2 The area to be designed for joints refers to the area where the airport pavement needs to arrange longitudinal and transverse joints, providing boundary restrictions for the arrangement of longitudinal and transverse joints. The joint baselines arranged by subsequent modules are all within the range of the area to be designed for joints. The area to be designed for joints is analyzed to obtain regional information, wherein the regional information includes the regional boundary, reference line, seam direction and the farthest distance from the reference line to the area to be designed for joints along the seam direction. The regional boundary refers to the boundary of the area to be designed for joints. The reference line refers to a joint baseline as a reference line for the automatic arrangement of longitudinal and transverse joints. The reference line for the longitudinal joint arrangement is generally located inside the joint area. The reference line for transverse joint arrangement is generally located on the sub-boundary of the joint area. The seam arrangement direction refers to the direction in which the joints are automatically arranged in batches. The longitudinal seam arrangement direction is perpendicular to the longitudinal seam arrangement reference line. The transverse seam arrangement direction is perpendicular to the transverse seam arrangement reference line. The farthest distance from the reference line along the seam arrangement direction to the area to be designed for the joint refers to the entire interval of automatic arrangement of longitudinal and transverse seams, which is the sum of all seam spacings automatically arranged at one time. Based on the regional information, a design base for the longitudinal and transverse joints of the airport is built to provide geometric support for the subsequent automatic arrangement of longitudinal and transverse seams.

[0076] S30: Acquire a plurality of seam spacing calculation intervals according to the regional information, and acquire seam spacing data based on the plurality of seam spacing calculation intervals and a preset longitudinal and transverse seam design algorithm, wherein the plurality of seam spacing calculation intervals include a standard interval, a local interval, and a non-parallel interval.

[0077] Specifically, the seam design area is divided into multiple seam spacing calculation intervals according to the regional information, such as Figure 3 As shown, the area to be designed for joints is divided into three types of seam spacing calculation intervals. Corresponding longitudinal and transverse joint design algorithms are used for different seam spacing calculation intervals, and the seam spacing data of the longitudinal and transverse joints of the airport pavement in the interval are automatically calculated within the area to be designed for joints.

[0078] S40: Inputting the seam spacing data into the joint template to automatically generate a design plan for the longitudinal and transverse joints of the airport pavement.

[0079] Specifically, the obtained seam spacing data is input into the joint template, all joint baselines are automatically arranged in the area to be jointed of the airport pavement, and the corresponding airport pavement longitudinal and transverse joint design plan is generated to improve the efficiency and accuracy of airport pavement joint design.

[0080] In this embodiment, in the process of designing the longitudinal and transverse joints of the airport pavement, basic joint data is obtained, and the basic joint data type is obtained through the basic joint data. The corresponding joint template is determined through the basic joint data type to provide data support for the subsequent calculation of the seam spacing data and the automatic arrangement of the joints; the regional information is obtained by analyzing the area to be designed for the joint, wherein the regional information includes the regional boundary, the reference line, the seam direction and the farthest distance from the reference line along the seam direction to the area to be designed for the joint; based on the regional information, a design base for the longitudinal and transverse joints of the airport is constructed to provide geometric support for the subsequent automatic arrangement of the longitudinal and transverse joints; the area to be designed for the joint is divided into a plurality of seam spacing calculation intervals according to the regional information; different seam spacing calculation intervals use corresponding longitudinal and transverse joint design algorithms; the seam spacing data of the longitudinal and transverse joints of the airport pavement in the area to be designed for the joint is automatically calculated within the area to be designed for the joint; the obtained seam spacing data is input into the joint template; all joint baselines are automatically arranged for the area to be designed for the airport pavement; the corresponding longitudinal and transverse joint design scheme for the airport pavement is generated, and the efficiency and accuracy of the airport pavement joint design are improved.

[0081] In one embodiment, if Figure 4 and Figure 5 As shown, in step S20, a plurality of seam spacing calculation intervals are obtained according to the area information, specifically including:

[0082] S21: Acquire a region sub-boundary based on the region boundary, and acquire a distance from the reference line to the region sub-boundary according to the region sub-boundary and the reference line.

[0083] S22: Integrate the distance from the reference line to the sub-boundary of the region and the sub-boundary of the region to form a boundary information set, generate a parallel boundary set based on a preset boundary information calculation rule, and determine whether the parallel boundary set is an empty set.

[0084] S23: When the parallel boundary set is an empty set, determine whether the maximum distance in the parallel boundary set is equal to the farthest distance from the reference line along the seam direction to the seam design area; if not, determine that the seam spacing calculation interval is a non-parallel interval.

[0085] S24: When the parallel boundary set is not an empty set, determining the seam spacing calculation interval to be a standard interval or a local interval.

[0086] Specifically, since the seam spacing scheme within the airport pavement longitudinal and transverse joint design area may be composed of multiple different seam spacing calculation intervals, where the seam spacing calculation interval includes a standard interval, a local interval and a non-parallel interval, the regional sub-boundary and the distance from the reference line to the regional sub-boundary are used as a boundary information set, the parallel boundary combination is calculated using a preset boundary information calculation rule, and it is determined whether the parallel boundary set is an empty set. According to the judgment result, the airport pavement longitudinal and transverse joint design area is divided into corresponding seam spacing calculation interval types, so that corresponding seam spacing calculation schemes can be adopted according to different seam spacing calculation intervals, thereby improving the accuracy of airport pavement joint design.

[0087] In one embodiment, as shown in step 4, in step S22, based on a preset boundary information calculation rule, a parallel boundary set is generated and it is determined whether the parallel boundary set is an empty set, which specifically includes:

[0088] S221: acquiring a regional sub-curve based on the regional boundary, determining whether the regional sub-curve is parallel to the reference line, and when the regional sub-curve is parallel to the reference line, acquiring a direction and a distance from the reference line to the regional sub-curve;

[0089] S222: Determine whether the direction of the reference line pointing to the regional sub-curve is the same as the direction of the fabric seam, and if so, determine whether the distance of the reference line pointing to the regional sub-curve is greater than a preset maximum seam spacing;

[0090] S223: When the distance from the reference line to the regional sub-curve is greater than the preset maximum seam spacing, the distance from the reference line to the regional sub-curve and the regional sub-curve are input into the boundary information and combined to form a parallel boundary set.

[0091] In one embodiment, if Figure 6 As shown, in step S30, based on the pavement information data, determining the pavement disease image in the highway construction to be monitored specifically includes:

[0092] S31: when the seam spacing calculation interval is a standard interval, generating a set of seam spacing arithmetic progressions based on a preset maximum seam spacing and a minimum seam spacing;

[0093] S32: generating a set of solutions for the seam spacing according to the set of arithmetic progressions of the seam spacing and the preset seam spacing constraint conditions;

[0094] S33: Determine whether the seam spacing solution set is an empty set. When the seam spacing solution set is not an empty set, determine minimum seam spacing solution data based on the seam spacing solution set, and output seam spacing data of a standard interval according to the minimum seam spacing solution data.

[0095] Specifically, when the seam spacing calculation interval is a standard interval, a seam spacing arithmetic progression set is generated for the standard interval according to the preset maximum seam spacing and minimum seam spacing, and the seam spacing arithmetic progression set and the preset seam spacing constraints are used to construct multiple binary linear inequalities, and the seam spacing arithmetic progression set is traversed to calculate a set of seam spacing solutions, and the minimum seam spacing solution data is selected from the seam spacing solution set, and the seam spacing data of the standard interval is output according to the minimum seam spacing solution data, and then the seam arrangement spacing set within the standard interval is calculated to realize the automatic design of the seam spacing scheme for the standard interval.

[0096] Furthermore, the preset seam spacing constraints include that all arranged seam baselines are parallel to the reference line and are located on the side of the reference line toward the seam direction; the seam spacing data ri is within the range of the maximum and minimum seam spacings AMax and AMin, that is, AMin≤ri≤AMax; the difference between two adjacent seam spacing values ​​is not greater than 0.5, that is, |r[i]-r[i+1]|≤0.5.

[0097] Furthermore, according to AMax and AMin, the set of arithmetic progressions of seam spacing DSet is constructed. Assuming that the spacing scheme is composed of a certain number of DSet[i] and DSet[i+1] combinations, multiple binary linear inequalities are constructed according to the combination and the overall algorithm constraints, and the set of interval seam spacing solutions RGSet is calculated by traversing DSet. The goal of the algorithm is to calculate the set of seam arrangement spacing RDSet within the standard interval, with the minimum number of spacings in the set, that is, S = Min(x1i+x2i).

[0098] In one embodiment, if Figure 7As shown, in step S30, based on the pavement information data, a pavement disease image in the highway construction to be monitored is determined, which specifically includes:

[0099] S34: obtaining the last baseline in the previous interval for calculating the distance between fabric seams, and using the last baseline in the previous interval for calculating the distance between fabric seams as a new reference line;

[0100] S35: updating the parallel boundary set based on the new reference line, determining whether the updated parallel boundary set is an empty set, and when the updated parallel boundary set is not an empty set, obtaining the last seam spacing data in the previous seam spacing calculation interval;

[0101] S36: updating the minimum seam spacing according to the last seam spacing data in the previous seam spacing calculation interval, and constructing a new seam spacing arithmetic progression set based on the preset maximum seam spacing and the new minimum seam spacing;

[0102] S37: Construct a binary linear inequality parameter set, traverse the inequality parameter set based on a preset inequality index, obtain inequality solution results according to a new seam spacing arithmetic progression set and seam spacing constraints, and generate seam spacing data based on the inequality solution results.

[0103] Specifically, after completing the calculation of the seam spacing data for the previous seam spacing calculation interval, obtain the last baseline in the previous seam spacing calculation interval and use it as a new reference line. Use the new reference line to update the parallel boundary set, and determine whether the updated parallel boundary set is an empty set. When the updated parallel boundary set is not an empty set, it means that the seam spacing calculation interval is a local interval. Obtain the last seam spacing data in the previous seam spacing calculation interval. The last seam spacing data in the previous seam spacing calculation interval will affect the calculation of the seam spacing data in the local interval. According to the preset seam spacing constraint, use the last seam spacing data in the previous seam spacing calculation interval to update the minimum seam spacing, the maximum seam spacing and the new minimum seam spacing to construct a new seam spacing arithmetic progression set. At the same time, construct a binary linear inequality parameter set, use the preset inequality index to traverse the inequality parameter set, and obtain the inequality solution result through the new seam spacing arithmetic progression set and the seam spacing constraint.

[0104] Furthermore, the inequality solution results include solutions and no solutions. When the inequality solution result is no solution, it is determined whether the inequality parameter set has been traversed. If not, the inequality parameter set is continued to be traversed until the inequality parameter set is completely traversed. When the inequality solution result is still no solution, a new maximum seam spacing is generated, and the seam spacing data calculation method of the standard interval is used with the new maximum seam spacing to generate seam spacing data; when the inequality solution result is a solution, the seam spacing data of the local interval is output based on the inequality solution.

[0105] Furthermore, when the solution result of the inequality parameter set is no solution, it is determined whether the inequality parameter set has been traversed. If not, the inequality parameter set continues to be traversed according to the preset inequality index, and the inequality solution is solved in real time until the inequality parameter set is traversed. If the inequality solution result is still no solution, it means that the local interval range is small, so a new maximum seam spacing is generated, and the seam spacing data calculation method of the standard interval is used with the new maximum seam spacing to generate the seam spacing data within the interval. When the inequality solution result is a solution, the seam spacing data of the local interval is output according to the inequality solution, and then the seam arrangement spacing set within the local interval is calculated to realize the automatic design of the seam spacing scheme for the local interval.

[0106] In one embodiment, if Figure 8 As shown, in step S30, the seam spacing data is obtained based on the plurality of seam spacing calculation intervals and the preset longitudinal and transverse seam design algorithms, which specifically also includes:

[0107] S38: when the seam spacing calculation interval is a non-parallel interval, obtaining the last baseline in the previous seam spacing calculation interval, and determining whether the last baseline in the previous seam spacing calculation interval is zero; when the last baseline in the previous seam spacing calculation interval is zero, using the maximum seam spacing as the seam spacing data;

[0108] S39: when the last baseline in the previous seam spacing calculation interval is not zero, obtaining a remaining spacing set, and obtaining a remaining available seam distance based on the remaining spacing set;

[0109] S310: Execute the following loop steps: "Traverse the remaining spacing set based on the preset traversal index, and record the accumulated seam distance in real time, and determine whether the accumulated seam distance is less than or equal to the remaining available seam distance;

[0110] S311: If yes, generate seam spacing data, and input the seam spacing data into the remaining spacing set to form a new remaining spacing set.

[0111] S312: until the data in the new remaining spacing set is equal to the maximum seam spacing, stop the above loop steps.

[0112] Specifically, when the seam spacing calculation interval is a non-parallel interval, it is analyzed whether the last baseline in the previous seam spacing calculation interval is zero. When the last baseline in the previous seam spacing calculation interval is zero, the maximum seam spacing is used as the seam spacing data of the non-parallel interval, and the seam arrangement spacing set RDSet is composed of AMAX, and the seam arrangement spacing set within the non-parallel interval is calculated.

[0113] Furthermore, when the last baseline in the previous seam spacing calculation interval is not zero, a remaining spacing set is obtained, the remaining spacing set ReDSet={RD1, RD2, | RDi = K + n×d, n∈N, d=0.5,1≤ n ≤ [(AMax -K) / d], the remaining arrangable seam distance is obtained through the remaining spacing set, the remaining spacing set is traversed according to a preset traversal index, and the cumulative seam distance is recorded in real time to determine whether the cumulative seam distance is less than or equal to the remaining arrangable seam distance. When the cumulative seam distance is less than or equal to the remaining arrangable seam distance, the corresponding seam spacing data is generated and input into the remaining spacing set to form a new remaining spacing set, until the data in the new remaining spacing set is equal to the maximum seam spacing, then the seam spacing data of the interval is generated according to the new remaining spacing set, and the seam arrangement spacing set within the non-parallel interval is calculated to realize the automatic design of the seam spacing scheme for the non-parallel interval.
