For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart of an implementation of a method for adjusting a louver angle based on parameterization according to an embodiment of the present invention, which is described in detail below:
step 101, building a building analysis model based on a building design scheme. The building analysis model comprises a shutter model; the shutter model is used for designing different shutter arrangement schemes.
The building analysis model mainly comprises a shutter model and a building body, and is used for simulating and analyzing indoor lighting conditions of the building body under different shutter arrangement schemes. When building the building analysis model, the building analysis model can be realized by Rhino software.
Different shutter arrangement schemes can be designed by setting parameters such as different sizes, positions, intervals, heights, starting point positions, control paths and the like in the shutter model. So that the architectural analysis model can conveniently analyze lighting of different shutter arrangement schemes.
And 102, respectively carrying out multi-objective evaluation on different shutter arrangement schemes to obtain at least one optimized arrangement scheme.
When the shutter arrangement scheme is evaluated, the embodiment of the invention mainly performs multi-objective evaluation from multiple aspects of economic cost, visual shielding area, style control and the like, so that each shutter arrangement scheme is comprehensively evaluated to screen out at least one optimized arrangement scheme. The economic cost comprises shutter quotation cost, construction cost and maintenance cost.
In some embodiments, step 102 may include:
and constructing a multi-objective evaluation function.
According toA multi-objective evaluation function may be constructed.
Wherein,representing multiple objective evaluation function values,/->Representing a first weight, ++>Mapping value representing the quoted cost of curtain wall shutter, < >>Representing a second weight, ++>Mapping value representing the visual occlusion area of a curtain wall shutter,/->Representing a third weight, ++>Mapping value representing the landscape control of the curtain wall shutter,/->Representing the fourth weight, ++>Mapping value representing construction cost of curtain wall shutter, < ->Representing a fifth weight, ++>A map value representing the maintenance cost of the curtain wall shutter.
The calculation formula of the mapping value of the quotation cost of the curtain wall shutter is as follows:. Wherein (1)>Represents the cost of the shutter quote in the current shutter arrangement scheme,/->Represents the maximum value of the cost of the shutter quote in all shutter arrangements,/->Representing the minimum cost of the blinds offer in all blinds arrangements.
The calculation formula of the mapping value of the visual shielding area of the curtain wall shutter is as follows:. Wherein (1)>Indicating the visual blocking area in the current shutter arrangement scheme,/->Represents the maximum value of the visual shielding area in all shutter arrangement schemes, < >>Representing the minimum value of the visual shielding area in all the shutter arrangement schemes.

Similarly, the mapping value of the wind aspect control of the curtain wall shutterMapping value of construction cost of curtain wall shutter ∈>Mapping value of maintenance cost of curtain wall shutter +.>The calculation can be performed according to the above formula for calculating the mapping value. The embodiments of the present invention are not described herein.
Wherein,. The weight values can be adjusted according to specific situations and requirements. The embodiment of the present invention is not particularly limited thereto. By adjusting the weight values, the proportional relation among the economic cost, the visual shielding area and the landscape control can be balanced according to specific requirements, so that the shutter arrangement schemes can be comprehensively evaluated.

And determining at least one shutter arrangement scheme corresponding to the maximum multi-objective evaluation function value as at least one optimized arrangement scheme.
It should be noted that, because the embodiment of the present invention adopts multi-objective evaluation, there may be more than one shutter arrangement scheme corresponding to the maximum multi-objective evaluation function value. Therefore, the embodiment of the invention determines the louver arrangement scheme corresponding to the maximum multi-objective evaluation function value as an optimized arrangement scheme.
By calculating the multi-objective evaluation function value corresponding to each shutter arrangement scheme, the optimized arrangement scheme can be screened out from a plurality of shutter arrangement schemes, so that lighting analysis can be conveniently carried out on each optimized arrangement scheme subsequently, and the calculated amount of subsequent lighting analysis is reduced.
And step 103, acquiring external lighting parameters and historical sunlight environment data of the total period, and inputting the external lighting parameters and the historical sunlight environment data into a building analysis model for simulation calculation to respectively obtain the optimal average rotation angles corresponding to the optimized arrangement schemes.
The external lighting parameters are used for representing the influence degree of external sun visors and/or shielding objects and the like on indoor lighting. By performing solar environment analysis on the historical weather data, the historical solar environment data can be correspondingly obtained. The Honeybee plug-in the Rhino software can be used for carrying out sunlight environment analysis on historical weather data so as to obtain historical sunlight environment data. The total time period herein may be any period of one week, one month, or one year. The embodiment of the present invention is not particularly limited thereto.

And inputting the external parameter values influencing indoor lighting and historical sunlight environment data of the past year into a building analysis model for simulation operation, so as to obtain the corresponding indoor lighting conditions when the curtain wall shutters are at different rotation angles under each optimized arrangement scheme, and further calculate and obtain the optimal average rotation angles corresponding to each optimized arrangement scheme.
In some embodiments, step 103 may comprise:
for each optimized arrangement scheme, external lighting parameters and historical sunlight environment data are input into a building analysis model, angle-by-angle simulation calculation is carried out, and a first lighting index value, a second lighting index value and a third lighting index value under each angle are respectively obtained.
When the simulation calculation is performed, the angle-by-angle simulation calculation can be performed according to the preset angle interval. Illustratively, the angular spacing may be 10 °. That is, from 0 °, simulation calculation is performed every 10 ° of rotation to obtain a first lighting index value, a second lighting index value, and a third lighting index value at each angle.
The first lighting index value in the embodiment of the inventionRefers to the percentage of time that the test point receives sunlight exceeding the illuminance threshold for an effective occupancy time (i.e., total period) for evaluating the indoor brightness. />The larger represents the higher the indoor brightness. Second lighting index value->The time percentage of the illuminance of the test point between the first preset value and the second preset value is indicated in the effective occupation time. Illustratively, the first preset value may be 100 and the second preset value may be 2000. When the illuminance value is between 100 and 2000, the human sense is more comfortable. The second lighting index value is used for evaluating the comfort of the indoor brightness. />The larger the representative indoor brightness is, the more suitable. The third lighting evaluation index refers to the time percentage when the illuminance of the test point exceeds the second preset value in the effective occupation time. When the indoor illuminance is too high, glare can be generated. The third lighting index value is used for evaluating indoor glare conditions. />The larger the indoor glare situation is, the more serious.
And determining the optimal average rotation angle corresponding to the current optimal arrangement scheme according to the first lighting index value, the second lighting index value and the third lighting index value under each angle.
According toCalculating an optimal lighting value corresponding to the current optimal arrangement scheme;
wherein,indicating the optimal lighting value, < > for>Representing the first index weight,/->A first lighting index value at the current angle, < +.>Representing the second index weight,/->A second lighting index value at the current angle, < +.>Representing a third index weight, ">A third lighting index value under the current angle is represented;
and determining the angle corresponding to the optimal lighting value as the optimal average rotation angle.
Namely, the lighting values under different angles are calculated respectively, and the maximum lighting value is the optimal lighting value corresponding to the current optimal arrangement scheme. The angle corresponding to the optimal lighting value is the optimal average rotation angle corresponding to the optimal arrangement scheme.
Wherein,. The weight values can be adjusted according to specific situations and requirements. The embodiment of the present invention is not particularly limited thereto.
Step 104, determining a final optimal arrangement scheme based on the optimal average rotation angle.
The optimal average rotation angle is obtained based on the indoor lighting effect. Meanwhile, when the optimal average rotation angle is too large, privacy leakage occurs, and when the optimal average rotation angle is too small, indoor ventilation is affected.
According to the embodiment of the invention, the average value of each optimal average rotation angle is calculated in advance, the deviation value between each optimal average rotation angle is calculated, and finally, the optimal arrangement scheme corresponding to the minimum deviation value is determined as the final optimal arrangement scheme.
The optimal arrangement scheme determined by the mode can ensure the indoor lighting effect and can also avoid the situations of revealing privacy and affecting indoor ventilation.
Step 105, performing time-interval simulation calculation based on the optimal arrangement scheme to obtain an optimal rotation angle corresponding to each unit time interval. The optimal rotation angles corresponding to the unit time periods form an angle adjustment strategy, and the curtain wall shutter performs angle adjustment based on the angle adjustment strategy.
And aiming at the optimal arrangement scheme, performing time-interval simulation calculation on the optimal arrangement scheme, and obtaining the optimal rotation angle in each unit time interval. Thereby forming an angular adjustment strategy.
In some embodiments, step 105 may include:
acquiring historical sunlight environment data of each unit time period;
and respectively inputting the historical sunlight environment data of each unit time period into a building analysis model for simulation calculation, and correspondingly obtaining the optimal rotation angle corresponding to each unit time period.
The unit time period here may be one hour, one day, one week, one month, or the like. The embodiment of the present invention is not particularly limited thereto.
According to the above, the historical sunlight environment data of each unit period is input into the building analysis model for angle-by-angle simulation calculation, so that the first lighting index value, the second lighting index value and the third lighting index value under different angles can be obtained, and the optimal lighting value in the unit period is determined. And determining the angle corresponding to the optimal lighting value as the optimal rotation angle.
The optimal rotation angles corresponding to the unit time periods together form an angle adjustment strategy for controlling the curtain wall shutter to perform angle adjustment. For the optimal arrangement scheme, the historical sunlight environment data of each month in the past year can be respectively obtained and respectively input into a building analysis model for simulation calculation, and the optimal rotation angle of each month is correspondingly obtained to form an angle adjustment strategy. The curtain wall shutter is subjected to angle adjustment regularly according to the angle adjustment strategy.

according to the embodiment of the invention, the optimized arrangement scheme is obtained by carrying out multi-objective evaluation on different shutter arrangement schemes; and calculating the optimal average rotation angle corresponding to each optimal arrangement scheme, thereby determining the optimal arrangement scheme of the curtain wall shutter.
