Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a structural intention of an indoor lighting control system based on the internet of things according to an embodiment of the present invention is provided. The indoor lighting control system based on the internet of things comprises: the device comprises a light intensity sensor 1, a main control device 2, video playing equipment 3, a user terminal 4 and a lighting system 5; the light intensity sensor 1 is arranged in a room in which the video playing device 3 is arranged and is used for detecting light intensity information of a region in which the video playing device 3 is arranged; the illumination system 5 is used for providing illumination of the area with a corresponding illumination intensity; the user terminal 4 is in communication connection with the video playing device 3 (may be wireless communication, such as WiFi communication or bluetooth communication), and is used for controlling the playing operation of the video playing device 3; the master control device 2 is communicatively connected (may be a wireless communication, such as a WiFi communication or a bluetooth communication) to the light intensity sensor 1, the video playing device 3, the user terminal 4, and the lighting system 5, and is configured to:
when the video playing device 3 plays, acquiring the light intensity information currently detected by the light intensity sensor 1, acquiring the display brightness currently set by the display screen of the video playing device 3 and the average value of the color gradation of each RGB channel of all pictures to be played in the next N seconds, and acquiring the user ID of the user terminal 4 in the area; n is more than or equal to 1;
based on the user ID, acquiring indoor movie watching lighting preference of the user;
determining the illumination intensity of the illumination system 5 in the current time period according to the indoor movie watching illumination preference of the user, the light intensity information, the display brightness and the average value of the color gradation; the current time period is the time period in which the next N seconds are located;
the illumination operation of the illumination system 5 is controlled in dependence on the illumination intensity.
In this embodiment, the preferences of different users for the illumination brightness of the indoor viewing environment are different, for example, the indoor viewing illumination preferences of the users may be bright, dark or centered. It should be noted that, by detecting the light intensity of the indoor viewing environment, the light and shade state of the current indoor viewing environment can be known, so that the accurate control of the illumination brightness of the indoor viewing environment is facilitated. In addition, when the video playing apparatus 3 plays indoors, since the display screen of the video playing apparatus 3 is also one of the light sources, the display brightness currently set by the display screen of the video playing apparatus 3 and the color level condition of the playing screen (the color level represents the brightness of the playing screen, the same display brightness setting is adopted, the higher the color levels of the RGB channels in different places of the playing screen are biased to white, the higher the illumination brightness of the display screen to the outside is, the more the color levels of the RGB channels in different places of the playing screen are biased to black, the lower the illumination brightness of the display screen to the outside are), so that the light intensity and brightness condition of the indoor viewing environment can be reflected more comprehensively, and the illumination brightness of the indoor viewing environment can be controlled precisely.
The ID of the user may be sent by the user terminal (for example, a mobile phone or a tablet computer) through camera recognition or fingerprint recognition, or may be input by the user.
Note that, the method for calculating the tone average value is as follows: and obtaining all pictures to be played in the next N seconds, carrying out average value calculation on the color levels of the RGB channels of the pixels of different picture areas of each picture to be played to obtain the average value of the color levels of the RGB channels of the picture to be played, and then carrying out average calculation on the average value of the color levels of the RGB channels of all pictures to be played to obtain the average value of the color levels of all the RGB channels of the picture to be played in the next N seconds. By calculating the average value of the color levels of all RGB channels of the picture to be played in the next N seconds, the comprehensive condition of the brightness change of the played picture in a period of time can be obtained, and therefore the illumination brightness of the indoor video watching environment can be well controlled. By way of example, N is 3 seconds, i.e. every 3 seconds, and the above-known information is combined to determine the illumination intensity of the illumination system 5 in the current time period (i.e. in the period of 3 seconds next to the current time).
By way of example, the video playback device 3 may be an indoor video playback device 3 such as a television or a projection screen, and is not particularly limited herein.
By way of example, the user terminal 4 may be used to control the playback operation of the video playback device 3.
In summary, the embodiment of the invention intelligently controls the indoor illumination brightness according to the light intensity of the indoor movie watching environment, the illumination preference of the user, the display brightness of the video equipment and the brightness change condition of the playing picture in real time, thereby providing an illumination environment which better meets the movie watching requirement of the user for the user and further improving the movie watching experience of the user.

and determining the illumination intensity of the illumination system 5 in the current time period based on the mapping relation between the illumination intensity and the indoor movie watching illumination preference of the user, the light intensity level, the display brightness level and the tone scale level.
In this embodiment, the mapping relationship between the four and the preset illumination intensity may be stored in a mapping table, so that the illumination intensity of the illumination system 5 in the current time period may be determined by a table lookup method as long as the numerical values of the four are determined. It can be understood that the mapping relationship between the four and the preset illumination intensity is set in advance according to an empirical value, or can be set in advance by a user according to the self-viewing illumination requirement. By way of example, if the user indoor viewing lighting preference may be three kinds of bright, centered and dark, the light intensity level of the current indoor viewing environment may be five kinds of dark, centered, bright and bright, the display brightness level may be five kinds of dark, centered, bright and bright, and the tone scale level may be five kinds of dark, centered, bright and bright. Of course, the finer the above-described correlation level setting, the more accurate the control of the indoor lighting.
