Description

Technical Field

[0001] The present invention relates to the technical field of big data analysis, and specifically to a method and system for lamp source layout in the process of lamp cabinet design. Background Art

[0002] Big data algorithms have been increasingly applied in various fields, and using measurement data for optimization calculation has become a new trend. Using big data algorithms can provide new solutions to existing technical problems. For example, in the process of lamp cabinet design, it is difficult to ensure uniform illumination distribution on the bottom surface of the lamp cabinet in the prior art. Specifically, there are the following two problems: First, the lamp sources are often fixed on the top surface of the lamp cabinet and cannot be adaptively adjusted according to the change of natural illuminance in the usage environment background. Second, in the prior art, the lamp source layout often relies on human experience, lacks data support, and has low efficiency and poor effects.

[0003] In recent years, with the continuous development of big data technology, optimizing the lamp source layout through data mining has become a feasible technical means. For example, the illuminance value data measured by an illuminometer can be used to quantitatively measure the uniformity of illumination distribution, thereby guiding the reasonable layout of lamp sources. However, the prior art only studies the analysis and evaluation of illuminance value data, but fails to feedback the illuminance value data to the lamp source layout link, resulting in insufficient utilization of data. In addition, how to make full use of illuminance value data for big data optimization calculation, how to construct an optimization objective function using illuminance value data, and how to reduce the complexity of the optimization variable values to adapt to engineering applications are still technical problems worthy of research. Therefore, in order to overcome the drawbacks of the prior art solutions, it is necessary to collect illuminance data using lighting measurement instruments such as illuminometers, and use big data algorithms to process and calculate the illuminance data, so as to realize the optimized layout of the lamp source positions.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0052] Before giving examples, it is necessary to elaborate on the application scenarios of the inventive concept of the present invention. The present invention is applied to the optimized layout of the light sources in the lamp cabinet.

[0053] Embodiment 1: As Figure 1 shown, this embodiment provides a method for the layout of light sources in the design process of a lamp cabinet. The method includes the following steps:

[0054] S1, obtaining first data; the first data includes the number N1 of horizontal lamp rails of the grid lamp rail, the number N2 of vertical lamp rails of the grid lamp rail, and the number M of light sources; the grid lamp rail is adsorbed on the top surface of the lamp cabinet; the grid lamp rail includes N1 uniformly distributed horizontal lamp rails and N2 uniformly distributed vertical lamp rails; the light source is connected to the grid lamp rail through a pulley.

[0055] Exemplarily, the horizontal length of the top surface of the lamp cabinet is 10 meters, and the vertical length is 6 meters. The number N1 of horizontal lamp rails of the grid lamp rail is obtained as 4, the number N2 of vertical lamp rails of the grid lamp rail is obtained as 6, and the number M of light sources is 4. The grid lamp rail is adsorbed on the top surface of the lamp cabinet through a fixing frame. The 4 horizontal lamp rails are uniformly distributed, and the spacing between each horizontal lamp rail is 2 meters. The 6 vertical lamp rails are uniformly distributed, and the spacing between each vertical lamp rail is 2 meters. The 4 horizontal lamp rails and the 6 vertical lamp rails together form the grid lamp rail. Any horizontal lamp rail and any vertical lamp rail of the grid lamp rail are interconnected. The light source is connected to the grid lamp rail through a pulley.

[0056] S2, calculate the longitudinal division number D2 according to the preset transverse division number D1; the longitudinal division number is equal to the number of light sources divided by the transverse division number; evenly divide the grid light track into D1×D2 track groups to obtain the first track group to the Mth track group; distribute the M light sources to the first track group to the Mth track group to obtain the first light source to the Mth light source and the first moving range to the Mth moving range; the first track group to the Mth track group are separated by adding fixed partitions; the bottom surface of the lamp cabinet is divided into B1×B2 bottom surface partitions according to the preset first bottom surface division number B1 and the second bottom surface division number B2 to obtain the first bottom surface partition to the Rth bottom surface partition; R is equal to the product of B1 and B2; install illuminance meters at the geometric center points of the first bottom surface partition to the Rth bottom surface partition, respectively, recorded as the first illuminance meter to the Rth illuminance meter.

[0057] Exemplarily, the number of horizontal divisions D1=2 is preset. Since M is 4, the number of vertical divisions D2=2 is calculated. The grid light track is evenly divided into 2×2 track groups to obtain the first track group to the fourth track group. The first track group to the fourth track group are separated by adding a fixed partition, and the four light sources are allocated to the first track group to the fourth track group. Among them, the light source allocated to the first track group is recorded as the first light source; the light source allocated to the second track group is recorded as the second light source; the light source allocated to the third track group is recorded as the third light source; and the light source allocated to the fourth track group is recorded as the fourth light source. The first track group to the fourth track group are respectively recorded as the first moving range to the fourth moving range. The first light source can only be moved by the pulley within the first moving range, the second light source can only be moved by the pulley within the second moving range, the third light source can only be moved by the pulley within the third moving range, and the fourth light source can only be moved by the pulley within the fourth moving range. There are two purposes for allocating the four light sources to the first to fourth track groups that are separated from each other: one is to avoid collisions between the light sources and damage to the light sources; the other is to narrow the range of variable values ​​for subsequent optimization analysis and improve calculation efficiency. According to the pre-set first bottom surface division number B1=2 and second bottom surface division number B2=2, the bottom surface of the light cabinet is divided into 2×2 bottom surface partitions to obtain the first to fourth bottom surface partitions. Install illuminance meters at the geometric center points of the first to fourth bottom surface partitions, respectively, and record them as the first to fourth illuminance meters.

[0058] S3, placing the lamp cabinet in an experimental environment with an ambient illumination of 0 lux, turning on the first light source to the Mth light source respectively, and moving the first light source to the Mth light source within a first moving range to an Mth moving range respectively, recording the illumination values ​​measured by the first illuminance meter to the Rth illuminance meter, and recording them as the first sample illumination group to the Rth sample illumination group.

[0059] Exemplarily, place the lamp cabinet in an experimental environment with an ambient illuminance of 0 lux. Turn on the first light source to the fourth light source respectively, and move the first light source to the fourth light source within the first moving range to the fourth moving range respectively. Record the illuminance values measured by the first illuminance meter to the fourth illuminance meter, which are denoted as the first sample illuminance group to the fourth sample illuminance group.

[0060] S4. Place the lamp cabinet in the usage environment, where the first light source to the Mth light source are all in the off state. Record the illuminance measurement values of the first illuminance meter to the Rth illuminance meter within a preset first measurement time, which are denoted as the first measured illuminance value to the Rth measured illuminance value. Calculate the optimal positions of the first light source to the Mth light source using the particle swarm optimization algorithm based on the first sample illuminance group to the Rth sample illuminance group, the first measured illuminance value to the Rth measured illuminance value, which are denoted as the first optimal position to the Mth optimal position. Move the first light source to the Mth light source to the first optimal position to the Mth optimal position respectively.

[0061] Exemplarily, place the lamp cabinet in the usage environment, where the first light source to the fourth light source are all in the off state. Record the illuminance measurement values of the first illuminance meter to the fourth illuminance meter within a preset first measurement time, which are denoted as the first measured illuminance value to the fourth measured illuminance value. The first measurement time is 60 seconds, and the first measured illuminance value to the fourth measured illuminance value is the average of the illuminance measurement values measured by the first illuminance meter to the fourth illuminance meter within the first measurement time. Since in the usage environment, the influence degrees of the bottom surface of the lamp cabinet at different positions by the occlusion shadows are different, there are significant differences in the illuminance measurement values of the first illuminance meter to the fourth illuminance meter. The first measured illuminance value, the second measured illuminance value, the third measured illuminance value, and the fourth measured illuminance value are 103 lux, 53 lux, 100 lux, and 62 lux respectively. This shows that without turning on the light source, the first bottom surface partition and the third bottom surface partition are relatively bright, while the second bottom surface partition and the fourth bottom surface partition are affected by occluding objects such as the lamp cabinet body, and the illuminance is relatively low. To make the illuminance of the first bottom surface partition, the second bottom surface partition, the third bottom surface partition, and the fourth bottom surface partition more uniform, calculate the optimal positions of the first light source to the fourth light source using the particle swarm optimization algorithm based on the first sample illuminance group to the fourth sample illuminance group, the first measured illuminance value to the fourth measured illuminance value, which are denoted as the first optimal position to the fourth optimal position. By moving the first light source to the fourth light source to the first optimal position to the fourth optimal position, the uneven illuminance in the usage environment can be compensated, and the illuminance of the first bottom surface partition, the second bottom surface partition, the third bottom surface partition, and the fourth bottom surface partition can be made more uniform.

The first to the fourth light sources can move on the first to the fourth track groups respectively. Record the moving ranges of the first to the fourth light sources as the first to the fourth moving ranges respectively.

Number the intersection points in the first to the fourth intersection point sets in the order of the positions of the intersection points from left to right and from top to bottom to obtain the intersection point numbers. Take the first intersection point set as an example, establish a two-dimensional coordinate axis with the geometric center point on the top surface of the lamp cabinet as the origin, and the scale of the two-dimensional coordinate axis is in meters. The position coordinates of the first intersection point in the first intersection point set are , the position coordinates of the second intersection point are , the position coordinates of the third intersection point are , the position coordinates of the fourth intersection point are , the position coordinates of the fifth intersection point are , the position coordinates of the sixth intersection point are .

[0068] Place the lamp cabinet in an experimental environment with an ambient illuminance of 0 lux. Turn on the first light source to the Mth light source respectively, and place the first light source to the Mth light source at the intersection points included in the first intersection point set to the Mth intersection point set, and read the illuminance values measured by the first illuminance meter to the Rth illuminance meter; when the light source is at the intersection point number corresponding intersection point position, the illuminance value measured by the illuminance meter is expressed as ; where is an integer variable taking values from 1 to R; is an integer variable taking values from 1 to M; is an integer variable taking values from 1 to , representing the intersection point number in the intersection point set; represents the number of intersections; Combine to to obtain the sample illuminance group; Traverse from 1 to R to obtain the first sample illuminance group to the Rth sample illuminance group.

Then turn off the first light source, turn on the second light source, and place the second light source at the intersection points included in the second intersection point set respectively, and read the illuminance values measured by the first illuminance meter to the fourth illuminance meter. Then turn off the second light source, turn on the third light source, and place the third light source at the intersection points included in the third intersection point set respectively, and read the illuminance values measured by the first illuminance meter to the fourth illuminance meter. Finally, turn off the third light source, turn on the fourth light source, and place the fourth light source at the intersection points included in the fourth intersection point set respectively, and read the illuminance values measured by the first illuminance meter to the fourth illuminance meter. Finally, obtain the first sample illuminance group to the fourth sample illuminance group. Among them, the first sample illuminance group is , , , . Taking as an example, means that only the first light source is turned on, and the first light source is located at the 1st intersection point position in the first intersection point set when the illuminance value measured by the first illuminance meter. means that only the first light source is turned on, and the first light source is located at the 2nd intersection point position in the first intersection point set When, the illuminance value measured by the first illuminance meter.
