[0002] With the advancement of technology, traditional manual lighting control methods are no longer able to meet users' demands for efficiency, intelligence, energy conservation, and environmental protection in modern architectural environments, especially in various buildings. In most buildings, lighting conditions in different rooms vary significantly due to room location and orientation, as well as external environmental factors (such as obstruction from surrounding buildings and sunlight angles at different times of day). Therefore, controlling the operating status of lighting equipment in each room according to the lighting needs at different times of day is crucial for indoor comfort, energy conservation, and the visual experience of indoor occupants.

[0003] The working status of existing lighting equipment depends on manual control by indoor personnel or timer-based control. For example, installing lamps of the same or different power in each room and keeping them in an on or fixed working mode manually or timed may result in excessive indoor lighting during periods of strong sunlight, resulting in energy waste, and insufficient indoor lighting during periods of weak sunlight, affecting users' normal use.

[0004] Therefore, how to intelligently control the on and off status of lighting equipment according to the lighting needs of different time periods, improve the intelligence level of lighting control, and save energy to the greatest extent while meeting indoor lighting needs has become an urgent problem to be solved.

When the computer program is executed by the processor, the following steps are implemented:

[0006] S1, based on A, obtain the intensity difference list D corresponding to the i-th target room i ={D i21 , D i32 ,……,D i(k+1)k ,……,D iR(R-1)},in,

[0007] S2, according to D i , get the intensity difference probability distribution function P corresponding to the i-th target room i .

[0008] S3, P i The value of the intensity difference corresponding to the third quarter is determined as P i The corresponding intensity difference threshold D 0 i .

[0009] S4, according to D i 、D 0 i The R preset time slices corresponding to the target date are used to obtain the T target time slices corresponding to the target date of the i-th target room.

The working status indicator is used to control the working status of the corresponding lighting devices, including on and off.

It can be seen that the difference in the historical average sunlight illumination corresponding to the target room at different preset time slices on the target date is measured, and the corresponding intensity difference threshold is obtained and used to merge the preset time slices, which increases the effective duration of each control and reduces the number of controls on the lighting equipment. By comparing the illumination provided by the lighting equipment and the illumination that needs to be supplemented by the lighting equipment, the working status indicator corresponding to each lighting equipment in the target room is obtained, which is used to indicate how to control the working status of the lighting equipment, while meeting the indoor lighting needs and saving energy to the greatest extent, thereby improving the intelligence level of lighting control.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

It is understood that, where appropriate, the above-mentioned terms used to distinguish similar objects can be interchanged so that the present invention can also implement other embodiments other than the above-mentioned illustrated embodiments or described embodiments.

[0016] This embodiment provides a lighting device control system, which includes a processor and a memory storing a computer program, wherein the memory also stores a target room information set A={A1, A2, ..., A i ,……,A M}, where the room information list A corresponding to the i-th target room i ={A i 1 , A i 2 , A i 3}, It refers to the historical average sunshine illumination of the target room i at the kth preset time slice on the target date. i 2 Refers to the illumination of all lighting devices corresponding to the i-th target room, A i 3 Refers to the target illumination corresponding to the i-th target room, i = 1, 2, ..., M, M refers to the total number of target rooms in the target building, k = 1, 2, ..., R, R refers to the total number of preset time slices. When the computer program is executed by the processor, the following steps are implemented, such as Figure 1 As shown:

[0017] S1, based on A, obtain the intensity difference list D corresponding to the i-th target room i ={Di21 , D i32 ,……,D i(k+1)k ,……,D iR(R-1)},in,

[0018] Among them, in most buildings, the lighting conditions in different rooms will vary greatly due to the room's location, orientation and external environmental factors (such as obstruction from surrounding buildings, sunlight angles in different time periods, etc.). Controlling the working status of lighting equipment in each room according to the lighting requirements in different time periods is of vital importance to the comfort of the indoor environment, energy conservation and the visual experience of indoor people.

[0019] Therefore, the target room in the target building refers to a room that may have significant differences due to the location, orientation, and external environmental factors of the room and thus requires lighting equipment control.

[0020] Illumination refers to equipment that provides lighting for a target room, such as various lamps. Illuminance is the amount of light received per unit area, typically expressed in lux, describing the intensity of the lighting provided by the lighting in the target room.

[0021] In indoor lighting design, different locations require different illumination levels. For example, the illumination requirement for an ordinary office is generally between 300-500 lux to ensure that employees can read, write, and perform other tasks comfortably. However, in locations with extremely high visual accuracy requirements, such as operating rooms, the illumination requirement may be as high as 1000 lux or above. Therefore, this embodiment obtains the target illumination for each target room based on actual conditions, that is, the contrast requirement for each target room.

[0022] Since different seasons, different weather conditions and different time periods of sunlight have a great impact on the lighting conditions in the target room, the target date can be in days, the preset time slice can be in hours or minutes, and the specific time setting of the preset time slice can be determined by the implementer according to actual conditions.

[0023] In order to predict the lighting conditions of the target room on the target date in advance, so as to determine in advance how to control the working status of each lighting device in the target room, this embodiment obtains the historical sunlight illumination data of each target room respectively, that is, the historical sunlight illumination corresponding to each preset time slice of the target date in several historical years, and then calculates the average value of the historical sunlight illumination data to obtain the historical average sunlight illumination corresponding to each target room at each preset time slice on the target date, which is used to characterize the sunlight conditions corresponding to the target room in each time period, and serves as the basis for controlling the working status of each lighting device in the target room.

[0024] On a specific target date, the sunlight conditions may remain unchanged or change very slightly over a period of time, and have the same or very similar impact on the change in illumination of the target room. Therefore, when the difference in the historical average sunlight illumination of the target room at different preset time slices on the target date is small, the corresponding preset time slices can be merged, which increases the effective duration of each control, reduces the number of controls on the lighting equipment, and improves the control efficiency and intelligence level of the lighting equipment.

[0025] The above measures the differences in the historical average sunlight illumination of the target room corresponding to different preset time slices on the target date, providing a data basis for merging the preset time slices, thereby increasing the effective duration of each control and reducing the number of controls on the lighting equipment, thereby improving the control efficiency and intelligence level of the lighting equipment.

[0026] S2, according to D i , get the intensity difference probability distribution function P corresponding to the i-th target room i .

[0027] Among them, P i The horizontal axis is the value of the intensity difference, P i The vertical axis is the probability value that the value of the intensity difference is less than or equal to the value of the corresponding horizontal axis. i It can be used to characterize the probability of the target room appearing under different intensity differences, providing a basis for the subsequent determination of the intensity difference threshold.

[0028] S3, P i The value of the intensity difference corresponding to the third quarter is determined as P i The corresponding intensity difference threshold D 0 i .

[0029] In order to improve the adaptability of the intensity difference threshold to the target building and the target room, this embodiment adaptively sets P to iThe value of the intensity difference corresponding to the third quarter is determined as P i The corresponding intensity difference threshold D 0 i , which is used to group preset time slices, thereby improving the accuracy of time slice combination.

[0030] The third digit represents the value at the 75% position after the intensity difference data are sorted from small to large. i The intensity difference corresponding to the third and fourth positions of D is used as the threshold, which can ensure the reliability and stability of the threshold to a certain extent. 0 i It can be used to determine whether the intensity difference of the target room exceeds the acceptable range, thereby providing a basis for further decision-making and processing.

[0031] S4, according to D i 、D 0 i The R preset time slices corresponding to the target date are used to obtain the T target time slices corresponding to the target date of the i-th target room.

[0032] In a specific embodiment, S4 further includes the following steps:

[0033] S41, according to D i and D 0 i , group the R preset time slices corresponding to the target date.

[0034] S42, obtaining T time slice combinations corresponding to the i-th target room on the target date.

[0035] S43: splice the preset time slices corresponding to the T time slice combinations respectively to obtain T target time slices corresponding to the i-th target room on the target date.

[0036] In a specific embodiment, S41 further includes the following steps:

[0037] S411, if D (k+1)k <D 0 i , the k+1th preset time slice and the kth preset time slice corresponding to the target date are assigned to the same combination.

[0038] S22, if D (k+1)k ≥D 0 i , the k+1th preset time slice and the kth preset time slice corresponding to the target date are allocated to different combinations.

[0039] Among them, if D (k+1)k <D0 i , it means that the historical average sunshine illumination corresponding to the k+1th preset time slice and the kth preset time slice corresponding to the target date are relatively close, that is, the sunshine conditions of the k+1th preset time slice and the kth preset time slice corresponding to the target date have a similar impact on the change of the illumination of the target room. Then, the k+1th preset time slice and the kth preset time slice corresponding to the target date can be assigned to the same combination, so that the lighting equipment can be controlled in the same way in the k+1th preset time slice and the kth preset time slice corresponding to the target date.

[0040] If D (k+1)k ≥D 0 i , it means that the difference between the historical average sunshine illumination of the k+1th preset time slice and the kth preset time slice corresponding to the target date is large, that is, the sunshine conditions of the k+1th preset time slice and the kth preset time slice corresponding to the target date have a large impact on the change of the illumination of the target room. It is necessary to allocate the k+1th preset time slice and the kth preset time slice corresponding to the target date to different combinations, so as to perform different controls on the lighting equipment in the k+1th preset time slice and the kth preset time slice corresponding to the target date, thereby improving the control efficiency and intelligence level of the lighting equipment.

[0041] According to D i and D 0 i The R preset time slices corresponding to the target date are grouped to obtain the T time slice combination corresponding to the target date of the i-th target room. This increases the effective duration of each control and reduces the number of controls on the lighting equipment, thereby improving the control efficiency and intelligence level of the lighting equipment.

[0042] In a specific embodiment, S43 further includes the following steps:

[0043] S31 , for any time slice combination, according to all preset time slices corresponding to the current time slice combination, obtaining the earliest first time point and the latest second time point corresponding to the current time slice combination in the target date.

[0044] S32: Taking the first time point as the starting time point of the target time slice corresponding to the current time slice combination, and taking the second time point as the ending time point of the target time slice corresponding to the current time slice combination, to obtain the target time slice corresponding to the current time slice combination.

[0045] Among them, by determining the earliest first time point and the latest second time point, and then determining the starting time point and ending time point of the target time slice, the specific time period corresponding to the time slice combination can be clarified, which serves as the basis for further analysis and processing of relevant data within the target time slice.

[0046] S5, according to A i 1 、A i 2 、A i 3 and T target time slices, obtain the work status indicator list H corresponding to the i-th target room i ={H i1 , H i2 ,……,H it ,……,H iT}, where H it It refers to the working status indicator of all lighting devices corresponding to the i-th target room at the t-th target time slice on the target date. The working status indicator is used to control the working status of the corresponding lighting devices, including on and off.

[0047] Among them, the work status indicator list H corresponding to the i-th target room is obtained i ={H i1 , H i2 ,……,H it ,……,H iT}, the working state of the corresponding lighting device can be controlled based on the working state indicator, that is, the corresponding lighting device can be controlled to be turned on or off.

[0048] In a specific embodiment, S5 further includes the following steps:

[0049] S51, according to A i 1 And T target time slices, get the predicted sunlight illumination list E corresponding to the target date of the i-th target room i ={E i1 , E i2 ,……,E it ,……,E iT}, where E it It refers to the predicted sunlight illumination corresponding to the t-th target time slice of the i-th target room on the target date, t = 1, 2, ..., T, T refers to the total number of target time slices.

[0050] Among them, since the lighting conditions of the same target room will vary greatly due to the sunlight angles in different time periods, seasons and weather conditions, and the seasons have a great influence on the sunlight conditions in the weather, therefore, when the seasons, time periods and weather corresponding to the same target date in different historical years are the same, the historical sunlight illumination corresponding to each preset time slice of the target date in the historical year can be used to predict the predicted sunlight illumination corresponding to each target time slice of the target room on the target date, which serves as the basis for measuring the lighting conditions of the target room in advance, thereby controlling the working status of each lighting equipment in the target room in advance.

[0051] In one embodiment, E it Obtain it through the following steps:

[0052] S511 : Determine the preset time slot corresponding to the t th target time slot of the i th target room on the target date as the middle time slot.

[0053] S512, according to A i 1 , calculate the average intensity of the historical average sunlight illumination corresponding to all intermediate time slices of the i-th target room on the target date.

[0054] S513: The average intensity is determined as the predicted sunshine illumination E corresponding to the tth target time slice of the i-th target room on the target date. it .

[0055] According to A i 1 And T target time slices, get the predicted sunlight illumination list E corresponding to the target date of the i-th target room i , as the basis for measuring the lighting conditions of the target room in advance, and thus controlling the working status of each lighting device in the target room in advance, it improves the intelligence level of lighting control.

[0056] S52, according to A i 3 and E i , get the required illumination list F corresponding to the target date of the i-th target room i ={F i1 , F i2 ,……,F it ,……,F iT}, where the required illumination F corresponding to the tth target time slice of the i-th target room on the target date is it =A i 3 -E it .

[0057] Among them, in order to achieve the target illumination corresponding to each target room and meet the lighting needs of users in each target room, the difference between the target illumination and the predicted daylight illumination is determined as the required illumination corresponding to the target room, that is, the illumination that needs to be supplemented by lighting equipment.

[0058] S53, according to A i 2 and F i , get the working status indicator list H corresponding to the i-th target room i ={H i1 , H i2 ,……,H it ,……,H iT}.

[0059] In a specific embodiment, the working status indicator includes a first indicator and a second indicator. in, Refers to the illumination of the jth illumination device corresponding to the i-th target room, j = 1, 2, ..., N(i), N(i) refers to the total number of illumination devices corresponding to the i-th target room, H it Obtain it through the following steps:

[0060] S531, if F it ≤0, the N(i) lighting devices corresponding to the i-th target room are all determined as non-target lighting devices.

[0061] S532, if According to F it and A i 2 , get the first demand intensity difference list Q corresponding to the tth target time slice of the target date for the i-th target room it ={Q it1 , Q it2 ,……,Q itj ,……,Q itN(i)}, where the first required intensity difference of the illumination of the jth lighting device corresponding to the i-th target room at the t-th target time slice on the target date is It refers to the maximum value function.

[0062] S533, Q it The lighting device corresponding to the minimum value greater than 0 is determined as the target lighting device.

[0063] S534, if Then The corresponding lighting device is determined as the target lighting device.

[0064] S535, Update Return to step S531 until the updated F it ≤0, and obtain all target lighting devices.

[0065] S536: Determine all lighting devices other than the target lighting devices among the N(i) lighting devices corresponding to the i-th target room as non-target lighting devices.

[0066] S537, the working status indicators of the target lighting equipment at the t-th target time slice on the target date are all determined as the first indicators, and the working status indicators of the non-target lighting equipment at the t-th target time slice on the target date are all determined as the second indicators, and H is obtained. it ={H it1 , H it2 ,……,H itj ,……,H itN(i)}, where H itj It refers to the working status indicator of the jth lighting device corresponding to the i-th target room at the t-th target time slice on the target date.

[0067] Among them, Q it The lighting device corresponding to the minimum value greater than 0 is determined as the target lighting device to maximize energy saving while meeting the indoor lighting needs.

[0068] The specific values ​​of the first indicator and the second indicator can be set by the implementer according to the actual situation. For example, the first indicator is set to 1 and the second indicator is set to 0 to distinguish how to control the working state of the lighting device.

[0069] As described above, by comparing the illumination provided by the lighting equipment and the illumination that needs to be supplemented by the lighting equipment, the working status indicator corresponding to each lighting equipment in the target room is obtained, which is used to indicate how to control the working status of the lighting equipment and save energy to the greatest extent while meeting the indoor lighting needs, thereby improving the intelligence level of lighting control.

[0070] In a specific embodiment, S5 further includes the following steps:

[0071] For any lighting device, if the working status indicator corresponding to the t-th target time slice of the current lighting device on the target date is the first indicator, the working status of the current lighting device on the t-th target time slice on the target date is controlled to be on.

[0072] In a specific embodiment, S5 further includes the following steps:

[0073] For any lighting device, if the working status indicator corresponding to the t-th target time slice of the current lighting device on the target date is the second indicator, the working status of the current lighting device on the t-th target time slice on the target date is controlled to be off.

[0074] Above, according to A, we get the intensity difference list D corresponding to the i-th target room i , according to D i Get the intensity difference probability distribution function P corresponding to the i-th target room i , P i The value of the intensity difference corresponding to the third quarter is determined as P i The corresponding intensity difference threshold D 0 i , according to D i 、D 0 i The R preset time slices corresponding to the target date are obtained, and the T target time slices corresponding to the target date of the i-th target room are obtained. i 1 、A i 2 、A i 3 and T target time slices, obtain the work status indicator list H corresponding to the i-th target room i , used to control the working status of the corresponding lighting equipment. It can be seen that the difference in the historical average sunlight illumination corresponding to the target room at different preset time slices on the target date is measured, and the corresponding intensity difference threshold is obtained and used to merge the preset time slices, which increases the effective duration of each control and reduces the number of controls on the lighting equipment. By comparing the illumination provided by the lighting equipment and the illumination that needs to be supplemented by the lighting equipment, the working status indicator corresponding to each lighting equipment in the target room is obtained, which is used to indicate how to control the working status of the lighting equipment, while meeting the indoor lighting needs and saving energy to the greatest extent, thereby improving the intelligence level of lighting control.
