Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a lighting control method for a large public building according to an embodiment of the present invention, which is applicable to lighting control of an indoor space of a large public building. The method can be realized by a large public building lighting control device which is configured in a computer device and can be specifically implemented by software and/or hardware in the computer device.

As shown in fig. 1, the lighting control method for a large public building specifically includes the following steps:

s110, acquiring illuminance data acquired by lighting modules of a plurality of subregions in a target lighting adjustment region and a plurality of environment factor parameters of each lighting module.

Specifically, the target illumination adjustment area may be an indoor illumination area in a large public building such as a mall, a supermarket, a hospital, an exhibition venue, a sports venue, or a house with a large space. Especially, in public lighting areas of hospitals, the medical experience is influenced when the illuminance changes greatly, and it is necessary to ensure stable illuminance. Since the area or space of the target illumination adjustment area is large, generally, a plurality of illumination light sources are disposed within the illumination area, in an arbitrary regular or irregular manner, above the illumination area space.

Furthermore, in order to collect the illuminance in the target illumination adjustment area, lighting modules may be disposed at a plurality of positions, and the lighting modules and the illumination light sources may be set in one-to-one number or in one-to-many proportion, which may be determined according to factors such as the application effect and the cost of the lighting modules, and one lighting module corresponds to a sub-area in one target illumination adjustment area.

In one embodiment, the environmental factor parameter may be at least one of a height of the lighting module, an angle of the lighting module, a distance of the lighting module from a central area, a usage time of the lighting module, a traffic of people in a corresponding area of the lighting module, and a number of light sources around the lighting module. Of course, it can be understood that, in the actual application process, the environment factor parameter may also include other parameters according to the requirements of the actual application scenario.

It can be understood that the environmental factor parameters are selected as the consideration indexes because the closer the lighting module is to the ground in a certain range, the more the actual illumination of the area can be reflected, and the higher the weight is; the more the lighting module is over against the ground, the more reliable the collected illuminance is, and the higher the weight is. The closer the lighting module is to the center of the area, the more the actual illumination of the area can be reflected, and the weight is higher; the longer the lighting module is used, the lower the weight of the lighting module is due to equipment loss; in areas with a large number of people, the higher the requirement on the stability of the illuminance is, the higher the importance of the lighting module in the corresponding area is; the more the number of the light sources around the acquisition module is, the more the lighting module is influenced by the light sources, and the more the obtained illuminance can not accurately reflect the whole illuminance of the area, so the lower the weight of the area is.

For example, as shown in fig. 2, a schematic diagram of displaying a target illumination space and an environmental factor shows that a certain number of light sources and lighting modules are arranged in a target illumination adjustment area, and corresponding environmental factor parameters including a distance from the lighting module to a central area, a pedestrian volume in an area corresponding to the lighting module, the number of light sources around the lighting module, an angle of the lighting module, and a height of the lighting module are shown. The height of the lighting module, the angle of the lighting module, the distance between the lighting module and the central area, the service time of the lighting module and the number of light sources around the lighting module can be collected in a pre-selection mode according to the setting of the light sources in the lighting area, and the flow rate of people in the area corresponding to the lighting module is data collected by a camera or other induction sensors and other devices, for example, 5-minute flow rate data is counted, and average calculation and other operations are carried out to determine the flow rate data in a period of time.

And S120, determining a comprehensive illumination value in the target illumination adjusting area according to the illumination data of each light collecting module and the plurality of environment factor parameters.

Firstly, determining the weight value of each lighting module to the integrated illumination value according to a plurality of environment factor parameters of each lighting module; then, the integrated illuminance value is determined based on the weight value and illuminance data of each of the lighting modules.

Specifically, the influence weight value of the plurality of environmental factor parameters on each lighting module may be calculated by an entropy method, and the weight value of each lighting module on the integrated illuminance value is determined. The specific process is as follows:

let M be the environment factor weight matrix of each lighting module, one row represents one lighting module, and one column represents one environment factor (or one attribute):

the following steps are used:

and calculating the contribution degree of the ith illumination module Li on the jth environment factor. With E_jRepresenting all illumination module pairs for the jth environmental factor X_jThe total contribution of (1), the term expression is:

in the formula

Thereby ensuring that E is more than or equal to 0_jLess than or equal to 1. From the above formula, it can be found that when the contribution degrees (P) of all the lighting modules to one environmental factor tend to be consistent, E_jTending to 1. This means that the attribute is the same for all lighting modules, there is no differentiating effect, and therefore the environmental factor should not be taken as a criterion or attribute for evaluation, i.e. the weight is 0.

From the above analysis, the degree of influence of a certain environmental factor (attribute) on the final result is determined by the difference of each sample in the environmental factor, and the larger the difference is, the larger the influence is, and vice versa. For example, if the height of all lighting modules is 5 meters, the environmental factor of height is not a valid factor, and is equivalent to the shared component of all samples, and has no effect on distinguishing the samples.

Further define d_jAs a measure of consistency of the contribution of the jth environmental factor to the lighting modules: d_j＝1-E_jTo d is paired_jAfter normalization, the weight expression of each attribute is as follows:

according to the above formula, when d is_jWhen equal to 0, W_jWhen the weight is 0, the environmental factor should be removed (E in this case)_j1, the environmental factor should be rejected according to the foregoing description), thereby ensuring that the calculation result is consistent with the actual situation。

The above process is based entirely on mathematical techniques to obtain the weight of each environmental factor, when some special conditions exist or there is a known weight factor (lambda) that is more effective_j) Then, the calculation formula of the weight factor can be updated as:

weighting according to different environmental factors

Calculating importance (weight) of each lighting module

Let the illuminance of each lighting module be V_iThen, the formula for calculating the comprehensive illuminance by each lighting module is as follows:

s130, calculating a difference value between the integrated illumination value and the ideal illumination value of the target illumination adjusting area, and controlling a light source of the target illumination adjusting area according to an illumination adjusting strategy corresponding to the difference value.

Specifically, let the ideal illuminance value V₀Therefore, the formula with the deviation value e of the actual integrated illuminance and the ideal illuminance is as follows: e-V₀。

Furthermore, the lighting module quantity Q of the target lighting adjusting area which is already turned on can be determined according to the illumination degree deviation value e, the comprehensive illumination value V of the target lighting adjusting area and the lighting module quantity Q of the target lighting adjusting area which is already turned on₁And the current outdoor illumination value V acquired by the outdoor lighting module₁And calculating and determining the illumination adjusting strategy.

Specifically, when the difference is greater than zero, it indicates that the actual integrated illuminance value is greater than the ideal illuminance value, and a certain number of light sources need to be turned off. The turned-on light source in the target illumination area can be usedDividing the value of the number of the modules by the difference value of the integrated illumination value and the outdoor illumination value, and multiplying the result value of the difference value by the value of the number of the modules to be turned off to obtain the number of the light source modules to be turned off, wherein the number of the light source modules to be turned off is represented by □ Q-Q₁/(V-V₁) E. It should be noted that if the number of lighting modules to be turned off is greater than the number of lighting modules already turned on, the illumination intensity adjustment may be performed by other means, such as dropping a curtain.

When the difference value is less than zero, the actual integrated illumination value is less than the ideal illumination value, and a certain number of light sources are required to be started. The absolute value of the difference may be divided by the difference between the integrated illuminance value and the outdoor illuminance value, and the resultant value multiplied by the number of turned-on light source modules in the target illumination area may be used as the number of light source modules to be turned on, which is formulated as □ Q ═ e |/(V-V)₁)*Q₁. It should be noted here that, if the number of lighting modules that need to be turned on is greater than the number of light source modules that are not turned on in the target lighting area, light supplement needs to be performed by other methods, such as opening a curtain, adding a new lighting module, and the like.

According to the light source adjusting strategy determined in the process, a certain number of light sources are turned off or on, so that the change degree of the illumination intensity in the target illumination area is reduced, the power consumption for illumination is effectively reduced, and the aim of managing and saving energy is fulfilled.

In the technical scheme of the embodiment, by comprehensively considering the illuminance data collected by the lighting modules of a plurality of sub-areas in the target lighting adjustment area and a plurality of environment factor parameters of each lighting module, the weight of each environmental factor is calculated by an entropy method, the importance of each acquisition module is further calculated, then calculating the comprehensive illumination value in the target illumination adjusting area through a weighting algorithm according to the importance of each module to ensure that the determined comprehensive illumination value is closer to the illumination value in the actual illumination area environment, further calculating the difference value between the integrated illumination value and the ideal illumination value of the target illumination adjusting area, and according to the illumination adjusting strategy corresponding to the difference value, and controlling the light source of the target illumination adjusting area to adjust the illumination intensity, so that the illumination intensity in the area is continuously stabilized in an ideal illumination intensity range, and the aim of managing and saving energy is fulfilled.

Step 9: and calculating the illumination deviation value e according to the comprehensive illumination.

According to standard industrial enterprise lighting design standard GB 50033-91, the lighting experience of living and public buildings is summarized, the lighting standard of domestic and foreign buildings is referred, the ideal illumination of a target lighting area is determined to be about 200(lx), and the deviation value of the current illumination to the ideal illumination is calculated:

e＝384.5–200＝184.5(lx)。

step 10: counting the total number Q of the lighting modules of the target lighting area and the number Q of the lighting modules which are turned on according to the illumination degree deviation value e₁Acquiring a current outdoor illuminance value V through an outdoor lighting module₁And the total illumination V calculates the number of the lighting modules which need to be turned off, □ Q-Q₁/(V-V₁)*e

If the number of the lighting modules to be turned off is larger than that of the lighting modules already turned on, the illuminance needs to be adjusted by other means, such as putting down a curtain.

If light supplement is needed, namely e is less than zero, a certain number of lighting modules in the target lighting area needs to be started: □ Q |/(V-V)₁)*Q₁。

If the number of the lighting modules needing to be started is larger than that of the lighting modules not being started in the target lighting area, light supplement is needed through other modes, such as opening a curtain, adding a new lighting module and the like;

and 11, step 11: and carrying out illumination control according to the control scheme.

An exemplary network topology of a lighting control system for a target lighting adjustment zone is shown in fig. 3. Each control module of the lighting control system may control multiple loops, 8 switching loops per lighting module. The target illumination adjustment zone has a total of six control modules and a total of 48 control loops.

200 lighting modules are on site, 100 lighting modules are already started, the current illumination deviation value is 184.5(lx), the outdoor illumination value is 150(lx), 79 lighting modules need to be closed, and the area illumination is reduced; after the illumination module is closed, the illuminance of the area can be reduced to reach an ideal illuminance value, the acquisition module acquires the illuminance value again, the illuminance deviation value is judged, the illumination module which needs to be started or closed is restarted, and the stability of the indoor illuminance is ensured. Wherein the on and off illuminance suggests a uniform distribution.

Further, in a specific application example, the light source in the target illumination adjustment area is controlled by the technical scheme in the embodiment, so that the energy consumption of illumination can be reduced, and the specific data analysis is as follows:

the monthly energy consumption of an emergency hall of a certain hospital is counted by respectively adopting a traditional control system and the control system of the embodiment, as shown in fig. 4, wherein the columnar data filled with pure color is the lighting energy consumption data of the traditional control system, and the columnar data filled with oblique lines is the lighting energy consumption data of the control system of the embodiment. As can be seen from the comparatives, the monthly power consumption using the lighting control method in this embodiment is significantly reduced from that of the conventional method.
