In order to make the objects, features and advantages of the present invention more comprehensible, the following description of the embodiments accompanied with the accompanying drawings in the embodiments of the present invention will make it apparent that the embodiments described below are only some embodiments but not all embodiments of the present invention. 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.
The invention provides a switch control method based on user requirements, which is used for solving the problem that a stepless switch in the prior art is difficult to accurately control the brightness of a lamp to meet the user requirements.
Referring to fig. 1, fig. 1 is a first flowchart of a switch control method based on user requirements according to an embodiment of the present invention.
S100, acquiring real-time activity information of a user, acquiring activity attributes of a current position area when the time for keeping the current position of the user exceeds a preset threshold time, and selecting corresponding illumination requirements according to the activity attributes;
the real-time activity information of the user is specifically the indoor position of the user, an infrared sensor or an ultrasonic sensor can be pre-installed in the indoor, and the current position of the user is detected according to an infrared positioning technology or an ultrasonic positioning technology; or detecting the position of the user according to the real-time image acquired by the indoor camera and the image recognition positioning technology; referring to fig. 2, the indoor plane structure diagram is divided into areas of each room, and the installation positions of each lamp during decoration and installation are marked, wherein the circular points are used as lamps, the indoor plane structure diagram is preset by a user, the user home plane diagram contains information of each room, such as a study room and a bedroom, the user can preset the room area in advance, the user is positioned on the plane diagram according to the real-time activity information of the user, the indoor position of the user is determined, and the user is positioned in which room to obtain the corresponding activity attribute;
the user real-time activity information also comprises time corresponding to the user position, when the user keeps at one position for more than a preset threshold time, the user can be regarded as the user needs to perform activity at the current position, and the preset threshold time can be set to be 1min or 30s; after judging that the user can move for a long time at a certain position in a room, combining the preset activity attribute of the position area, judging the current illumination requirement of the user, for example, that the user is in a study room area for more than 1min, judging that the user has a reading requirement, wherein the illumination of the position of the user needs to be adjusted to be suitable for reading, or that the user is in a bedroom area for more than 1min, judging that the user has a resting sleep requirement, and the illumination of the position of the user needs to be adjusted to be suitable for resting; based on different activity attributes, corresponding illumination requirements are set to be quantized into illumination, the illumination is measured by Lux (Lux), specific values of the illumination requirements are set according to individual requirements of users, the illumination required for the middle is set to be 200Lux, and the illumination required for reading is 600Lux in the embodiment.
S200, acquiring a user home plan, and identifying a first lamp in the same space according to current activity information of a user; the method comprises the steps of obtaining illumination information of each first lamp, calculating the distance between each first lamp and the current position of a user, substituting the distance into a lamp brightness combination model to obtain PWM (pulse width modulation) switch control proportion of each first lamp, wherein the lamp brightness combination model specifically comprises:
;
wherein,for the illumination of the illumination demand->The PWM switch control ratio for the nth first lamp is +.>Less than or equal to 1 +>Rated power for the nth first luminaire, < >>For the light effect of the nth first luminaire, < >>For the distance of the nth first luminaire from the current position of the user, < >>For the minimum value of the total power of the first luminaire, < >>The number of the first lamps in the same space;
it should be noted that the user home plan view also contains the installation position of each lamp and the specification information of each lamp, and the specification information comprises the rated power and the light efficiency of the lamp; the light efficiency is a parameter of a lamp light source, is a ratio of luminous flux to power, and can bring light of a certain lumens (Lm) per watt, namely Lm/w, and the calculation formula is as follows: luminous flux = power x light effect, and multiplying the power and the light effect to obtain the luminous flux of the corresponding lamp; in the method for controlling the brightness of the LED lamp by the stepless switch, the duty ratio can be set by the PWM pulse regulating switch, the duty ratio is the flicker time proportion of the LED lamp in unit time, the brightness of the LED lamp is reduced due to continuous lighting of the LED lamp based on human eye vision residues, and the brightness of the lamp, namely the luminous flux, is correspondingly regulated according to the proportion of the duty ratio;
the illumination required by illumination ensures the luminous flux on a unit area, the light of the lamp is emitted to the periphery, the position of the user only receives illumination on a certain angle, and the farther the distance from the lamp is, the less the intensity of the luminous flux is, so that the illumination is inversely proportional to the square of the distance from the first lamp to the current position of the user; under the PWM switch regulation and control brightness combination of the first lamp, a combination scheme with the minimum total power consumption is further selected, so that the minimum energy consumption under the illumination requirement of a user is met.
S300, setting pulse proportion of the corresponding stepless switch according to PWM switch control proportion of each first lamp.
It should be noted that, each first lamp is connected with a PWM control stepless switch, and brightness can be controlled based on PWM pulse adjustment; because the perception of the human eyes to the light is limited, when the brightness of the lamp changes within a certain range, the human eyes cannot perceive the change of the brightness, when the high level time of the PWM signal occupies a small proportion of the whole period, the brightness of the lamp is darker, and when the high level time of the PWM signal occupies a large proportion of the whole period, the brightness of the lamp is brighter, so that the dimming effect of the lamp is formed;
when a user performs activities in a certain area, the first lamps are possibly only turned on, even if all the first lamps in the room are not turned on, in order to ensure life experience and visual comfort of the user, the lamps in the area where the user is located are required to be automatically turned on after the user is detected to perform continuous activities, and the corresponding PWM switch control proportion is set, so that illumination realized at the position where the user is located is comprehensively achieved by each first lamp to meet the current requirements of the user.
In this embodiment, through monitoring the real-time position of the user, after determining that the user performs long-term activity at a certain indoor position, the illumination requirement of the user is obtained based on the regional activity attribute corresponding to the position of the user, and how the brightness of each lamp is adjusted according to the lamp brightness combination model, so that the current illumination requirement of the user can be met under the condition of lowest energy consumption, the lamp can be automatically and accurately adjusted to the brightness meeting the activity requirement of the user during the activity, the use experience and the adjustment accuracy of the stepless switch of the lamp are improved, the use comfort of the user is increased, and the energy consumption is reduced.
