[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0040] Figure 1 This is a flow chart provided by an embodiment of a method for calculating the optimal solar radiation envelope of the present invention. Figure 1 , this embodiment may include the following steps:

[0041] S1 cuts the base of the envelope into multiple small squares;

[0042] S2 Identify existing buildings;

[0043] S3 randomly samples the sunshine conditions, and calculates the sun position that ensures the preset sunshine time according to the sunshine conditions on the windows of the existing buildings;

[0044] S4 calculates the height of each of the small squares according to the sun position, thereby generating an enveloping space body;

[0045] S5 repeats step S3 and step S4 to iterate and generate a plurality of envelope space bodies;

[0046] S6: Determine the optimal sunlight envelope space volume among the multiple envelope space volumes according to the user's selection.

[0047] It should be noted that the envelope base: determines the site boundary of the envelope calculation. If the envelope base is the total land area of ​​the entire building plan, the analysis results can be used to determine which piece is suitable for building a building, which plays a certain auxiliary role in planning. If the location of the building to be built in the plot has been determined, it can be defined as the envelope base for calculation. The calculated results can be used to determine the style of the building that can be built.

[0048] Existing buildings: existing buildings involved in the analysis and calculation.

[0049] Window (along the line): Any sampling line or window that needs to maintain the sunlight standard under the influence of the selected existing buildings and proposed buildings.

[0050] It can be understood that in this embodiment, S1 cuts the base of the envelope into multiple small squares, S2 determines the existing buildings, S3 randomly samples the sunshine conditions, and calculates the sun position that ensures the preset sunshine time according to the sunshine conditions on the windows of the existing buildings, S4 calculates the height of each of the small squares according to the sun position, thereby generating an envelope space body, S5 repeats steps S3 and S4 to iterate, and generates multiple envelope space bodies, and S6 determines the optimal sunshine envelope space body among the multiple envelope space bodies according to the user's selection. By quickly and efficiently calculating the largest "envelope space body" that cannot be broken through when meeting the sunshine, the design department can flexibly design and adjust the plan based on the "envelope diagram" generated by analysis, which greatly improves the efficiency of the design and can be used as a reference to optimize the space utilization to the greatest extent.

[0051] Preferably, step S1 comprises:

[0052] Determine the grid sampling spacing;

[0053] The envelope base is cut into multiple small squares with the grid sampling spacing as the side length.

[0054] It can be understood that the envelope base is cut into small squares according to the grid sampling spacing. For example, if the grid sampling spacing is 2, the size of the small square is 2*2. (The small square serves as a basic calculation unit. In the subsequent calculation process, the small square will be treated as an independent individual, and the maximum height of each small square will be calculated. Finally, the heights are combined to form the final "maximum envelope space".)

[0055] Preferably, step S3 includes:

[0056] Random sampling of sunshine conditions;

[0057] Based on the sampling results, the solar altitude angle and azimuth angle that ensure the windows of existing buildings have the preset sunshine time are calculated.

[0058] It is understandable that, according to the selected existing buildings and windows (along the line), a preliminary sunshine analysis is first performed to calculate the sunshine conditions on the windows when only the existing buildings are blocking them. The sunshine conditions are randomly sampled, and the sun position at the moment of 120 minutes is calculated while ensuring 120 minutes of sunshine time (sunshine time is greater than or equal to 120 minutes). The position of the sun is a three-dimensional arc as a whole, and the sun position at different times has different altitudes and azimuths.

[0059] Preferably, step S4 comprises:

[0060] According to the solar altitude angle, the maximum height of each small square is calculated; when any height of the small square does not block the windows of the existing buildings, the height value of the small square is the upper limit of the height;

[0061] Generate an enveloping space volume according to the height of each small square.

[0062] It is understandable that the height of each small square is calculated according to the altitude angle of the sun's position. This height is the critical value. If it is greater than this height, the window (along the line) will be blocked. If any height is impossible to block, then the height value is set to the upper limit, for example, the upper limit is set to 100 meters.

[0063] Preferably, step S5 includes:

[0064] The genetic algorithm is used to repeat steps S3 and S4 for iteration, thereby generating a plurality of envelope space bodies.

[0065] It is understandable that after step S4, the height of each small square can be obtained, that is, small square right prisms of different heights. By combining these right prisms, a set of right prisms, that is, an "envelope space body", can be obtained, and the volume of this envelope space body can be calculated. However, this envelope space body is calculated based on the sun's position at the random 120-minute satisfying moment, and may not be the largest and optimal envelope space body.

[0066] In order to obtain the optimal envelope space body, it is necessary to loop step S3 and step S4 to calculate different envelope space bodies generated under random sampling, that is: repeat random sampling of sunshine time -> calculate the maximum height of the small square according to the position of the sun -> calculate the volume of the envelope space body at this time. The envelope space body calculated in each cycle is called the nth generation envelope space body. Since each generation is randomly sampled, the results may be disordered, so a genetic algorithm is used to optimize the results generation by generation. The algorithm is as follows: the largest value is selected from the volume of the calculation results of each generation, and the volume value of the calculation result of the next generation is compared with the maximum volume value. If it is greater than 90% of the maximum volume value, the calculation result is considered valid, otherwise the result is directly ignored and recalculated. In this way, it can be ensured that the volume value trend of the calculation results of each generation gradually increases.

[0067] However, the largest volume value does not mean the best. Therefore, it is necessary to record and display the maximum height and three-dimensional shape of the small squares of each generation of enveloping space bodies, so that designers can select the best result.

[0068] The present invention also provides a device for calculating the optimal sunlight enveloping space volume, which is used to implement the above method embodiment.

[0071] The envelope space body generating module 3 is used to calculate the height of each small square according to the position of the sun, so as to generate the envelope space body;

[0072] Iteration module 4 is used to repeatedly perform random sampling on the sunshine conditions to generate multiple enveloping space bodies;
