Example 1
Referring to fig. 1, the present embodiment provides an indoor lighting control method, which includes the following steps:
step S101, powering up when acquiring biological information entering the room. In this step, the biological information may be a signal of a person or other animal entering the room.
In step S102, image data of the room is collected by the camera 20, and the indoor area is divided on the image data to form the illumination area 24 and the adjustment area 25.
The illumination area 24 can be divided into a plurality of areas according to the indoor area in the step, so that the illumination of local places is improved, and the illumination area can be finely regulated and controlled; the same applies to the adjustment region 25 which may be divided into a plurality of sections.
Step S103, obtaining brightness values of the illumination area 24 and the adjustment area 25, setting an adjustment threshold value, and adjusting the brightness or the illumination direction of the lamplight according to the threshold value.
Specifically, the threshold value can be a range value manually set, and is illustrated by taking a range value which can be read indoors in daytime as 200-550 lux as an example, and when the threshold value is within or exceeds the range value, the indoor lighting does not need to be started; when the value is smaller than the range value, the lamplight needs to be started, and the indoor space is in the range of 200-550 lux. If the brightness of the local area is lower than the range value, the brightness of the darker area can be improved by adjusting the light irradiation direction, so that the indoor illumination has no dead angle.
In order to be convenient for adjust the too high problem of indoor luminance, can control indoor (through motor and solenoid valve control for the motor just reverses, realizes opening or close the effect of curtain 23 automatically, and then control indoor luminance), and then opens light and regulate and control for indoor luminance is in 200 ~ 550lux range value, in order to avoid the too bright problem of light. For example, if the light is too bright in a classroom, the reading or teaching quality can be affected, and an effect of providing a good bright environment indoors can be achieved.
Step S104, acquiring a gesture signal of biological information, adjusting the brightness or the irradiation direction of lamplight in the illumination area 24 or the adjustment area 25, and simultaneously stopping acquiring image data; and when a gesture signal for ending the gesture operation is acquired, the indoor image data acquisition is carried out again.

Specifically, the illumination mode may be a normal light adjustment, that is, the illumination intensity may be adjusted within a range of 200 to 5501ux in the same manner as the adjustment of the illumination area 24. And in the tracking mode, in which the tracking mode,
and S106, acquiring an indoor temperature value, judging whether the temperature value exceeds a set dangerous value, and if so, performing alarm warning. Specifically, the temperature value is high-temperature early warning, for example, when the temperature is above 40 ℃, the warning of the high-temperature early warning can be issued to indicate that the indoor temperature is too high, and the problem should be solved in time.
And S107, recording the indoor people number according to the acquired image data, and powering down when the people number is zero and exceeds a preset time threshold. Specifically, when judging that no person is in the room, the device is closed only after a period of time, for example, 3 minutes or 5 minutes, so that the situation that the person is temporarily away is avoided, and the practicability is improved.
Example two
As shown in fig. 2, the present embodiment provides an indoor lighting control system, which performs adjustment control according to the indoor lighting control method described in the first embodiment, and includes an image capturing module 10, an image processing module 11, an illumination module 12, a detection module 13, a gesture acquisition module 14, a positioning module 15, and a control module 16.
The camera module 10 in this embodiment may be an infrared camera 20, which is used to obtain indoor image data. The lighting module 12 may be a plurality of groups of LED lamps, and an adjusting seat for adjusting the irradiation angle of the angle is arranged on the LED lamps, and the lighting module 12 is used for adjusting the illumination intensity according to the brightness value or the definition value. The detection module 13 may be a photosensor for acquiring a biological signal entering the room and a biological signal leaving the room. The gesture acquisition module 14 may be a reflective infrared sensor, for acquiring indoor gesture signals; the positioning module 15 may be an information positioner 22, and is used by embedding and sealing on a bottom plate of the room (opening or closing a sealing groove cover for use), so that the indoor area is divided by the positioning module 15, and an illumination area 24 and an adjustment area 25 are formed; the control module 16 may be a single-chip microcomputer, such as a single-chip microcomputer of the STC89C52, and obtains picture data, a biological signal or a gesture signal, and a brightness value, a definition value and a person number value information of the picture data, so as to adjust, turn on or off the lamp operation of the indoor lighting module 12, and set a time threshold for turning off the indoor lighting control system. For convenience of explanation, the room in the classroom will be described below as an example.
Specifically, when the detection module 13 obtains a signal that a person or an animal enters the room, the signal is fed back to the control module 16, and the control module 16 starts the indoor lighting control system (i.e. power-on operation); at this time, the camera module 10 acquires indoor picture information by shooting and feeds the picture information back to the control module 16, and the control module 16 acquires a brightness value, a definition value and the number of people on the picture by an image processing function; the indoor area of the picture is divided into an illumination area 24 and an adjustment area 25 by the signals fed back by the positioning module 15, so that the effect of separate control can be achieved, for example, normal illumination regulation and control can be performed in the seat area of the student; in the platform area of the teacher, corresponding light adjustment can be performed according to the requirements; or, in the illumination area 24 or the adjustment area 25, the gesture signal can be acquired by the gesture acquisition module 14 to perform corresponding adjustment, so that the purpose of adjusting the corresponding illumination area 24 or the adjustment area 25 according to the gesture signal is achieved, the purpose of performing corresponding adjustment according to the self requirement is achieved, and the adaptability is improved.
For example, the light adjustment of the adjustment zone 25 may be switched between an illumination mode, a tracking mode, or an illumination mode without light, which may be adjusted according to a specific teaching scenario. Specifically, for the brightness adjustment of the lamplight, setting a range value of a threshold value, and describing with a range value of 200-550 lux which can be read indoors in daytime; therefore, when the detection value is within or exceeds the range value, the indoor lighting does not need to be started for illumination; when the value is smaller than the range value, the lamplight needs to be started, and the indoor space is in the range of 200-550 lux. If the brightness of the local area is lower than the range value, the brightness of the darker area can be improved by adjusting the light irradiation direction, so that the indoor illumination has no dead angle.
In order to facilitate the problem of excessive brightness in the adjusting room, a motor can be arranged on the curtain 23 in the classroom, and is electrically connected with the control module 16, and the aim of lowering or lifting the curtain 23 in the room can be further controlled by forward and reverse rotation of the hole motor. Therefore, in an excessively bright room, the curtain 23 can be put down, and then the light can be turned on to regulate and control, so that the indoor brightness is within the range of 200-550 lux, and the problem of excessively bright light is avoided. For example, if the light is too bright in a classroom, the reading or teaching quality can be affected, and an effect of providing a good bright environment indoors can be achieved.
Further, the illumination area 24 and the adjustment area 25 may be divided into more areas, and when a person is in one of the illumination areas 24, the brightness in the illumination area 24 can be controlled by gestures; for example, when the camera module 10 is in a standby state, until the control of the gesture module is released, the camera module 10 acquires a photo to perform indoor brightness adjustment, so that the practicability and autonomy of gesture adjustment are realized.
For example, a lecture area (adjustment area 25) in the teaching room, which can be adjusted in real time under the lecture demands of a teacher; when the explanation of the PPT is carried out, the dimming can be regulated and controlled so as to clearly display the content of the PPT (no light mode); when writing and teaching of the blackboard is performed, illumination of the blackboard position can be ensured, and teaching contents can be cleaned and displayed (illumination mode); if the lecture is teaching, the stage light tracking type illumination can be adopted to perform the effect (tracking mode) of the performance teaching; various illumination modes can improve the adaptability and practicality of illumination.
Further, as shown in fig. 2, the embodiment further includes a photoelectric detection module 13, where the photoelectric detection module 13 is disposed at the indoor entrance and the number of people in the recording room is accumulated, and the photoelectric detection module 13 is electrically connected to the control module 16. The photoelectric detection module 13 is provided with two photoelectric sensors, one for detecting the photoelectric sensor entering the room and one for detecting the photoelectric sensor leaving the room; when someone enters the room, the accumulated number is increased by one; similarly, when a person leaves the room, the accumulated number is reduced by one, so that the number of people in the room is calculated; meanwhile, people count is carried out through the acquired photos regularly, correction is carried out on the photos and the total number of people, correction and adjustment are carried out based on the number of people on the acquired photos, so that the total number of people information in a classroom can be acquired, record information is formed and stored, and the recorded information can be uploaded to the cloud for storage, so that the practicability is improved.

The processor may be a single-chip microcomputer (not shown in the figure) of the STC89C52, where the camera 20, the positioner 22, the first photoelectric sensor 26, the second photoelectric sensor 27, and the infrared sensor are electrically connected in parallel to an input end of the processor, and the lighting lamp set 21 is electrically connected to an output end of the processor.
Specifically, when the first photoelectric sensor 26 obtains a signal that a person or an animal enters the room, the signal is fed back to the processor, and the processor starts the indoor lighting control device (i.e. power-on operation); at this time, the camera 20 acquires indoor picture information by shooting and feeds the picture information back to the processor, and the processor acquires a brightness value, a definition value and the number of people on the picture by an image processing function; the indoor area of the picture is divided into an illumination area 24 and an adjustment area 25 by the signals fed back by the positioner 22, so that the effect of separate control can be achieved, for example, normal illumination regulation and control can be performed in the seat area of the student; in the platform area of the teacher, corresponding light adjustment can be performed according to the requirements; or, in the illumination area 24 or the adjustment area 25, the gesture signal can be obtained through the reflective infrared sensor to perform corresponding adjustment, so that the purpose of adjusting the corresponding illumination area 24 or the adjustment area 25 according to the gesture signal is achieved, the purpose of performing corresponding adjustment according to the self requirement is achieved, and the adaptability is improved.
For example, the light adjustment of the adjustment zone 25 may be switched between an illumination mode, a tracking mode, or an illumination mode without light, which may be adjusted according to a specific teaching scenario. Specifically, for the brightness adjustment of the lamplight, setting a range value of a threshold value, and describing with a range value of 200-550 lux which can be read indoors in daytime; therefore, when the detection value is within or exceeds the range value, the indoor lighting does not need to be started for illumination; when the value is smaller than the range value, the lamplight needs to be started, and the indoor space is in the range of 200-550 lux. If the brightness of the local area is lower than the range value, the brightness of the darker area can be improved by adjusting the light irradiation direction, so that the indoor illumination has no dead angle.
In order to facilitate the problem of excessive brightness in the adjusting room, a motor can be arranged on the curtain 23 in the classroom, and is electrically connected with the control module 16, and the aim of lowering or lifting the curtain 23 in the room can be further controlled by forward and reverse rotation of the hole motor. Therefore, in an excessively bright room, the curtain 23 can be put down, and then the light can be turned on to regulate and control, so that the indoor brightness is within the range of 200-550 lux, and the problem of excessively bright light is avoided. For example, if the light is too bright in a classroom, the reading or teaching quality can be affected, and an effect of providing a good bright environment indoors can be achieved.
Further, the illumination area 24 and the adjustment area 25 may be divided into more areas, and when a person is in one of the illumination areas 24, the brightness in the illumination area 24 can be controlled by gestures; for example, when the camera module 10 is in a standby state, until the control of the gesture module is released, the camera module 10 acquires a photo to perform indoor brightness adjustment, so that the practicability and autonomy of gesture adjustment are realized.
For example, a lecture area (adjustment area 25) in the teaching room, which can be adjusted in real time under the lecture demands of a teacher; when the explanation of the PPT is carried out, the dimming can be regulated and controlled so as to clearly display the content of the PPT (no light mode); when writing and teaching of the blackboard is performed, illumination of the blackboard position can be ensured, and teaching contents can be cleaned and displayed (illumination mode); if the lecture is teaching, the stage light tracking type illumination can be adopted to perform the effect (tracking mode) of the performance teaching; various illumination modes can improve the adaptability and practicality of illumination.
As shown in fig. 4, in the present embodiment, two photosensors are provided by a first photosensor 26 for detecting a photosensor entering a room and a second photosensor 27 for detecting a photosensor leaving the room; when someone enters the room, the accumulated number is increased by one; similarly, when a person leaves the room, the accumulated number is reduced by one, so that the total number of people in the room is calculated; meanwhile, people count is carried out through the acquired photos regularly, correction is carried out on the photos and the total number of people, correction and adjustment are carried out based on the number of people on the acquired photos, so that the total number of people information in a classroom can be acquired, record information is formed and stored, and the recorded information can be uploaded to the cloud for storage, so that the practicability is improved.
Further, the embodiment further includes an alarm unit (not shown), which is a buzzer or a warning lamp. For example, when the temperature in the room is too high (more than 40 degrees celsius), an alarm can be sent out to prompt people to process or escape, so that the safety is improved.
As shown in fig. 4, the embodiment further includes a control terminal 28 electrically connected to the processor, and a display screen is disposed on the control terminal 28. The control terminal 28 may be a mobile phone or a computer, and may use a wireless communication connection, or perform a wired communication connection through a computer, so that a set threshold value of brightness may be input, and a temperature value of early warning may be set; meanwhile, the acquired information (brightness value, definition value, number value information and the like) can be displayed on the display screen, so that corresponding information can be acquired manually, and the practicability is improved.
