in the dynamic stretching process of the variable template, if the variable template exceeds the upper limit, automatically dividing groups, and constructing branches for the groups, so as to ensure the road accessibility of each group of building groups;
s40, generating a variable template meeting the requirements according to the input and integration of the data;
integrating all input data, and constructing an initial variable template consisting of a building monomer unit 101, a distributed hard land unit 102 and an outer ring road unit 103 according to a splicing mode corresponding to each type of building data, wherein the process is shown in FIG. 8; the structure of the variable template has already been described in the above, and is not described herein again;
the variable template has a self-adaptive stretching rule, the stretching rule is generated according to the input information data, and the variable template simultaneously has the limiting requirements of the upper limit of the transverse stretching multiple, the upper limit of the longitudinal stretching multiple, the upper limit of the building number and the like; by defining different stretching rules in the variable templates, arranging buildings in the stretched templates regularly and setting the stretching times of any template in the transverse and longitudinal directions, the building groups of any state building can be simplified by using the stretching rules, so that the parameterization, classification and modularization characterization of the building groups are realized.
The variable template not only comprises a specific building, but also is a combination, a splicing and a surrounding of various buildings, and is more approximate to the design tendency of architects in actual arrangement. The stretching rule and the parameter setting are obtained by performing composite calculation according to the relevant data of the selected building.
In this embodiment, the stretching rule of the variable template is as follows:
s401, the expression of the stretching ratio of the variable template in the transverse direction/longitudinal direction is as follows: α = k n + i, where n is an integer, k is a positive integer, i is an integer, and i < k, α ≧ 1, α is used to denote the stretch multiple of the variable template in a certain direction; k represents that when the building single units 101 are arranged in every k rows, the buildings in the direction reach the upper limit, and the buildings can be continuously arranged only by arranging a branch, so that the traffic accessibility of the buildings is ensured; n represents the number of plots that reached the upper k value; i represents the arrangement line number of the block building which does not reach the upper limit k value;
as shown in fig. 9, in the longitudinal direction, k =2, that is, 2 rows of land parcels are arranged longitudinally, and k =3 in the transverse direction, that is, 3 columns of land parcels are arranged transversely, a branch needs to be arranged, and the transverse stretching multiple of the template is 4, and finally k =3, n =1, i =1 is obtained, that is, the template is divided into 2 land parcels in the transverse direction, 3 branches, and 4 columns of buildings are juxtaposed; and the longitudinal stretching multiple of the template is 7, and finally k =2, n =3 and i =1 are obtained, namely the template is transversely divided into 4 land parcels and 3 branches, and 7 rows of buildings are juxtaposed.
S402, after the variable template is stretched along the transverse/longitudinal stretching multiple alpha, the actual length L = Lc + n Ln + i Li of the variable template in the direction, wherein Lc, Ln and Li are calculated by an initial template, a building grouping mode and a specification parameter, and templates formed by different land mass numbers, branch numbers and building numbers under any stretching multiple can be finally represented by the same expression. Since k represents the upper limit of the sub-plot building in the direction (a branch needs to be additionally supplemented for sub-plot division), n represents the number of the sub-plots with full buildings arranged in the direction, and i represents the number of the buildings in the remaining sub-plots without full arrangement; ln thus represents the sub-plot length of the fully-arranged buildings in the direction, Li represents the sub-plot length corresponding to i buildings in the sub-plot, and Lc represents the corresponding calculation constant term;
through step S402, each initial template adapts to the general expression form of the stretching rule of the variable template under different input information according to the input grouping; step S402 is to calculate according to the input enclosing mode and the standard parameters, and generate a series of variable template sets with different { Lc, Ln, Li } parameter values from the initial template of the first step according to different enclosing modes. Each variable template corresponds to a configuration building and a configuration rule thereof, and the configuration and the pushing of an architect on the building in an actual project are represented by the method.
And S50, sorting and outputting the variable templates, wherein the variable templates are sorted and output according to different application scenes of the different variable templates.
In step S50, the application scenarios of different variable templates include:
the compact group-arranged variable template is suitable for the building layout of an industrial park;
the variable templates arranged in a staggered loose group are suitable for the building layout of the residential area;
the enclosed group is suitable for the building layout of an office park.
The enclosing mode of the building unit 101 in the variable template is shown in fig. 10 and comprises a compact type group, a staggered type group and an enclosing type group, wherein the enclosing type group comprises four forms in total.
Through the steps, the variable template generator finally outputs a plurality of variable template sets which meet the requirements of users and are most frequently used, and the variable template sets are used for arrangement and solution of the follow-up templates.
The invention provides a method for automatically generating a grouping mode of a multi-modal building, which provides a brand-new concept idea of 'variable templates' aiming at the characteristics of the layout of the multi-modal building, integrates road information, land parcel information and building monomer information into a template which can be freely stretched and adaptively adjusted by simulating the conception mode and the design experience of architects in the actual design, and realizes the accurate simulation of various types of building arrangement and the layout characteristics of the multi-modal building by inputting detailed and comprehensive parameters. According to the idea of the variable template, the complexity of the building layout solution is reduced to a great extent, so that the problem of the multi-modal building layout is converted into a mathematical model which can be automatically optimized and solved in a limited time by a computer.
In the traditional design industry, the layout of multi-modal buildings often requires a team of architects with different large amounts of professional knowledge and practical experience to perform manual forced arrangement and knock for a long time. By the method, a user is not forced to be a professional with professional knowledge or practical experience any more, and any user can perform the following steps: if the plot model is uploaded, the layout scheme generated by the device can be automatically acquired in a short time after the project information and the parameters are input.

According to the method, the executed and outputted results are as shown in fig. 11 to fig. 14, and four variable templates for arrangement are outputted, wherein the variable template 1 in fig. 11 represents a group arranged only by using light steel plants, and the arrangement mode of the light steel plants can be adaptively changed along with the stretching and adjustment of the templates and the road network of the group; the variable template 2 of fig. 12 represents a group arranged only with an independent-like factory building, which automatically changes its splicing type along with template adjustment, such as double-splicing/L-type triple-splicing; the variable template 3 of fig. 13 represents a poster center, which is not stretch adjustable; the variable template 4 in fig. 14 is the multi-modal composite template generated in step S40: the method comprises the following steps of constructing light steel plants, independent-like plants, business recruitment centers and the like, comprehensively calculating according to construction data and related parameters, and dynamically adjusting the splicing and combining modes of the internal buildings along with the stretching of templates so as to enable the ground mass in the buildings to reach the maximum building density. The four templates can be used for carrying out interactive operation very conveniently, so that the design process is simplified, the operation is simplified, and the results are diversified, as shown in fig. 15.
