In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

First embodiment:

This embodiment proposes a land plot design method, which can apply the relevant knowledge of urban environment and climate to the land plot design, and design a city more suitable for human habitation.

As shown in Figure 1, the plot design method of the present embodiment includes:

Step 101. Obtain the preset dimensions, physical properties, and functional properties of various types of abstract building blocks; wherein, the abstract building blocks are virtual three-dimensional spaces, and the virtual three-dimensional spaces are used to set up virtual buildings. Different types of abstract buildings The bases of the building blocks have the same shape and size;

In this embodiment, the abstract building blocks may be pre-stored in the system, and these abstract building blocks may be set by the user and/or set by the software provider, that is, the default setting of the system.

The physical properties of abstract building blocks include but are not limited to volume ratio, building density, building height limit, underlying surface properties, etc. The abstract building block of this embodiment can be understood as a three-dimensional space with a limited height, and various buildings to be built can be set in the three-dimensional space according to functional attributes and physical attributes, such as gymnasiums, high-rise residences, public toilets, parking lots, roads and swimming pool and more. Different types of abstract building blocks can have different attributes such as floor area ratio, building height limit, and building density.

It is conceivable that the plot to be designed generally needs to have multiple functions, such as providing users with living, shopping, or providing company offices, etc. The larger the plot to be designed, the more complex the functions it may undertake. In this embodiment, abstract building blocks with different functions are provided to facilitate the design of plots to be designed. Among them, the functional attributes of the abstract building blocks include, but are not limited to: industrial areas, commercial areas, residential areas, cultural and educational areas, and mixed areas. If it is required that the plot to be designed has other functions, in this embodiment, abstract building blocks with corresponding functional attributes can be set.

In this embodiment, the system can identify various types of virtual building blocks based on information such as models, drawings, and pictures stored, and extract the dimensions, physical attributes, and functional attributes of abstract building blocks.

Step 102, obtaining the size of the plot to be designed, the target floor area ratio and surrounding environment parameters;

Among them, the target floor area ratio is generally defined by the user, in order to obtain the optimal or better layout of the air-heat environment under the predetermined floor area ratio requirements. The surrounding environmental parameters of the plot to be designed include but are not limited to the surrounding construction area, building height, building density, green area, and climate information.

In this embodiment, the system can identify based on the input information such as models, drawings, and pictures of the land to be designed, and extract information such as the size of the land to be designed, the target volume ratio, and surrounding environmental parameters.

Step 103, determining the total number of abstract building blocks that can be set in the plot to be designed;

In this embodiment, in order to facilitate the design, the shape of the bottom surface of the abstract building block can be set to a regular shape that can realize seamless splicing, such as square, rectangle, rhombus, pentagon, hexagon, etc. no limit.

When determining the total number of abstract building blocks that can be set in the plot to be designed, the plot to be designed can be divided according to the bottom surface shape and size of the abstract building block, and a plurality of sub-regions that are seamlessly connected can be divided (understandable) The shape and size of each sub-area are the same as the shape and size of the bottom surface of the abstract building block), and a sub-area is used as a setting position of a virtual building block.

Optionally, in an example, a rasterization method can be used to divide the design plot. In step 103, determining the total number of abstract building blocks that can be set in the design plot includes:

The plot to be designed is rasterized according to the shape and size of the bottom surface of the abstract building block;

Determine the total number of grids that can be used in the plot to be designed. The total number is the total number of abstract building blocks that can be set in the plot to be designed. Among them, the area of a plot to be used that can be framed by a grid is the same as a The ratio of the area of the grid is not lower than the preset ratio.

A grid has the same shape and size as the base of an abstract building block. The preset ratio can be 50%, 60%, etc., and can also be set according to actual needs, which is not limited in this embodiment. It can be understood that if the plot to be designed has an irregular shape, some edge regions of the plot to be designed may not belong to any usable grid.

Step 104, according to the size, physical properties and functional properties of various types of abstract building blocks, as well as the size of the plot to be designed, the target volume ratio and surrounding environmental parameters, determine the various types of abstract buildings set in the plot to be designed The number of blocks and the position of each abstract building block are obtained to obtain the current proposed design scheme of the plot to be designed;

In this embodiment, the sum of the number of virtual building blocks set on the plot to be designed in the currently proposed design scheme is equal to the total number calculated in step 103, and in order not to affect the user's experience of living and living, create an environment For a city with a suitable climate, the difference between the plot ratio of the plot to be designed in the current design plan and the target plot ratio is within the preset error range. In this embodiment, the calculation method of the plot ratio of the plot to be designed in the currently proposed design scheme is: according to the preset volume ratios of various types of abstract building blocks, each abstract set on the plot to be designed in the currently drafted design scheme Calculate the average volume ratio of the building block, and use the average volume ratio as the volume ratio of the plot to be designed in the current proposed design scheme. In this embodiment, the average volume ratio can be slightly higher than the target volume ratio or slightly lower than the target volume ratio, and the preset error range can be set according to actual needs, such as not lower than -1% of the target volume ratio and not higher than 1% of the target FAR and so on.

In step 104, it can be understood that the specific type, quantity and location of the abstract building blocks used on the plot to be designed in the current draft design scheme can be determined according to the actual situation of the plot to be designed, and the current draft design scheme For the plot to be designed, the number of certain types of abstract building blocks can be 0.

Step 105: According to the physical attributes, functional attributes and positions of the abstract building blocks on the plot to be designed in the currently proposed design scheme, score the plot to be designed to obtain the scoring result of the currently proposed design scheme, which is used to reflect the current The impact of the proposed design scheme on the urban environment and climate of the design plot;

In practice, building density, building height, and green area in a city will all have an impact on the city's environmental climate. For example, changes in the underlying surface properties such as vegetation coverage, roughness, and soil moisture will change the local air system. water and energy budgets, which in turn affect the local climate. Scholars have proposed that the urban environmental climate map is an analysis tool that reflects the relationship between the local climate environment and urban planning, but the urban environmental climate map is generally made by collecting actual information after the city is built. In this embodiment, an idea of optimizing urban design by reversely using relevant knowledge of urban environmental climate (or urban environmental climate map) is proposed.

In order to inversely use the urban environmental climate map, in this embodiment, the urban environmental climate of the plot to be designed in the current proposed design scheme is analyzed to obtain the impact of the current proposed design scheme on the urban environmental climate of the plot to be designed. Among them, the scoring result can be the score of the urban environment and climate of the plot to be designed, such as at least one of the wind and heat environment evaluation score of the plot to be designed, the degree of dispersion of functional areas, the level of pollutants, the proportion control of functional areas, and the population density. A sort of.

Optionally, according to the physical properties, functional properties and positions of the abstract building blocks on the plot to be designed in the currently proposed design scheme, the plot to be designed is scored, and the scoring results of the currently proposed design scheme include:

According to the physical attributes and functional attributes of each abstract building block on the plot to be designed in the currently proposed design scheme, the basic assignment of each abstract building block is carried out;

According to the physical attributes, functional attributes and positions of the abstract building blocks on the plot to be designed in the current proposed design scheme, additional value assignments are made to each abstract building block, and the additional assignment is used to reflect the surrounding environment of the abstract building block. block impact;

According to the basic assignment and additional assignment of each abstract building block on the plot to be designed in the currently proposed design scheme, score the plot to be designed in the currently proposed design scheme to obtain the scoring result of the currently proposed design scheme.

Among them, it can be understood that the basic assignment reflects the virtual building block and its own attributes, such as physical attributes and functional attributes. Wherein, the surrounding environment of the abstract building block includes the environment formed by other abstract building blocks around the abstract building block.

The influence of the surrounding environment of the abstract building block on the abstract building block includes the relative position between the abstract building blocks, and the mutual influence between the abstract building blocks, such as the environmental changes caused, the relationship between functional areas, and the status of pollutants.

In order to diversify the scoring results or to increase the accuracy of the scoring results, in this embodiment, the assignment of each abstract building block on the plot to be designed can also be changed or expanded according to the user's needs, which is not limited in this embodiment.

Step 106: If the preset end condition is not currently met, adjust the various types of abstract buildings distributed on the plot to be designed based on the preset optimization algorithm, according to the scoring results of the currently proposed design scheme and the current proposed design scheme The quantity and/or position of the block obtain at least one new proposed design scheme, use the new proposed design scheme as the current proposed design scheme and return to execute according to the physical properties of each abstract building block on the plot to be designed in the current proposed design scheme, Functional attributes and locations, a step of scoring the plot to be designed, wherein, in each proposed design scheme for the plot to be designed, the sum of the numbers of abstract building blocks set on the plot to be designed is equal to the total number, and The difference between the plot ratio of the plot to be designed and the target plot ratio is within the preset error range;

Step 107: If the end condition is currently satisfied, then based on the scoring results of the proposed design schemes obtained for the plot to be designed, determine at least one proposed design scheme as an ideal design scheme for the land to be designed.

For a plot to be designed, it generally requires multiple rounds of design scheme optimization to obtain a scheme that is balanced in all aspects of the urban environment and climate or that is outstanding in a single aspect of the urban environment and climate. In order to rationally optimize the proposed design scheme of the plot to be designed, avoid the separation of the proposed design scheme and the environmental climate of the plot, and improve the efficiency of plot design, in this embodiment, the urban environmental climate map is reversed, and the urban environmental climate and the optimization algorithm Linkage to automatically adjust the virtual building blocks in the proposed design scheme.

In this embodiment, the important point is that when adjusting the various types of abstract building blocks distributed on the plot to be designed, it is ensured that the sum of the numbers of abstract building blocks distributed on the plot to be designed remains unchanged and equal to that in step 103. The determined total quantity and the difference between the average plot ratio and the target plot ratio of the plot to be designed are guaranteed to be within the preset error range.

It is conceivable that, based on the preset optimization algorithm, according to the scoring results of the current proposed design scheme and the current proposed design scheme, the number and/or positions of various types of abstract building blocks distributed on the plot to be designed are adjusted to obtain At least one new proposed design scheme can be adjusted so that aspects of the current proposed design scheme that perform poorly in the urban environment climate or aspects that are valued by users can be improved. For example, in the currently proposed design scheme, the air-thermal environment evaluation score of the plot to be designed is poor, and the wind-thermal environment evaluation score of the plot to be designed can be optimized by increasing the number of abstract building blocks with a large green area. It can be understood that the actual land plot design is more complicated, and there are many factors to be considered, the above description is only for illustration, and does not have any restrictions on the optimization of the proposed design scheme in this embodiment.

Wherein, the preset optimization algorithm includes but not limited to genetic algorithm, neural network algorithm, particle swarm algorithm and annealing algorithm.

In this embodiment, the end condition includes but is not limited to: the accumulative quantity of the proposed design scheme exceeds the preset design quantity; or, an instruction to stop the design input by the user is received. The end condition can also be additionally set as required, which is not limited in this embodiment.

During the execution of the plot design method in this embodiment, a large number of proposed design schemes may be generated. In order to reduce the amount of data processing, some of these proposed design schemes can be selected to perform well in at least one aspect of the urban environment and climate. The proposed design scheme is regarded as the ideal design scheme.

Optionally, based on the scoring results of each proposed design scheme obtained for the land to be designed, determining at least one proposed design scheme as an ideal design scheme for the land to be designed includes:

Display the scoring results of each proposed design scheme, and select the ideal design scheme according to the user's input;

Or, select the ideal design scheme according to the preset selection criteria and the scoring results of each proposed design scheme.

Among them, when the user inputs, he can directly choose the proposed design scheme he likes, or he can input the urban environment and climate requirements that the ideal design scheme needs to meet according to the actual needs of the project or his own understanding, and the system selects according to the needs of the user. According to the preset selection criteria and the scoring results of each proposed design scheme, when selecting an ideal design scheme, the system can choose a proposed design scheme that performs well in a certain aspect, such as the wind-heat environment, and can also choose a design scheme that performs well in various aspects of the urban environment and climate. A balanced design solution is not limited in this embodiment.

In this embodiment, in order to facilitate the user to have a more intuitive understanding of each proposed design scheme when selecting, a three-dimensional model of the plot to be designed can be generated for each proposed design scheme, and the step of designing the three-dimensional model can be performed in each In the proposed design scheme, it is to be carried out after the design of the abstract building block on the design plot is completed, or after the design of all the proposed design schemes is completed, which is not limited in this embodiment.

After the ideal design scheme is selected, a multi-dimensional evaluation space can also be set, in which different coordinate axes are used to represent different scoring results, so as to display each ideal design scheme more intuitively. To enable users to understand more intuitively the focus of different ideal design schemes. Optionally, after determining at least one proposed design scheme as the ideal design scheme for the land to be designed based on the scoring results of each proposed design scheme for the plot to be designed ,Also includes:

Establish an evaluation coordinate system in the multi-dimensional evaluation space, and each coordinate axis in the evaluation coordinate system represents a type of evaluation result;

According to the scoring results of the ideal design scheme, the ideal design scheme is displayed in the multi-dimensional evaluation space.

Wherein, if there are many types of scoring results of design schemes, multiple different attributes can be set for points corresponding to each ideal design scheme in the multidimensional evaluation space, and one attribute can be used to represent one scoring result of an ideal design scheme. For example, in a three-dimensional evaluation space, the x-axis represents the scoring result 1, the y-axis represents the scoring result 2, and the z-axis represents the scoring result 3. Therefore, each ideal design scheme can correspond to a spatial position in the three-dimensional evaluation space. If the ideal design scheme has other types of scoring results, attributes such as size, color, and shape can be set for points in the three-dimensional evaluation space. The attributes of point size, color and shape respectively represent a type of scoring result, for example, the color of the point represents the scoring result of 4, the size of the point represents the scoring result of 5, and the shape of the point represents the scoring result of 6, thus reflecting the ideal design scheme in the same multidimensional evaluation space. It is conceivable that the number of point attributes can be set according to the number of scoring results of the design scheme. Optionally, the sum of the number of point attributes and the number of coordinate axes in the multidimensional evaluation space is not lower than the scoring result of an ideal design scheme sum of types.
