Description

A control system for an intelligent table lamp

technical field

The invention belongs to the technical field of smart home, and in particular relates to a control system of a smart desk lamp.

Background technique

Desk lamp is a common lighting appliance in daily life. At present, the usual desk lamps are manually controlled. On the one hand, people often forget to turn off the light and cause huge energy waste. On the other hand, the existing desk lamps lack intelligence. The brightness cannot be adjusted according to the surrounding environment.

In the prior art, some simple smart desk lamps have been proposed, for example, they can be turned on and off according to whether there are people around them, or their own brightness can be adjusted according to the intensity of ambient light. However, these intelligences are relatively rough and simple, and lack the ability to adapt to specific environmental conditions in practical applications. The actual environment is diverse, and intelligent brightness adjustments need to be made according to more conditions.

Contents of the invention

The object of the present invention is to provide a control system for an intelligent desk lamp, so as to solve the technical problems in the prior art that the intelligentization of the desk lamp is rough and the lack of intelligent brightness adjustment for specific environments.

In order to solve the above technical problems, the present invention adopts the following technical solutions:

A control system for an intelligent desk lamp, comprising a lighting lamp, a control module, a power supply module, a human body detection module, a height detection module, an environment humidity detection module and an environment light intensity detection module. The power supply module supplies power to the lighting lamp, the control module, the human body detection module, the height detection module, the ambient humidity detection module and the ambient light intensity detection module respectively, and the human body detection module, the height detection module, the environmental humidity detection module and the ambient light intensity detection module The output terminals of the control terminal are connected with the input terminal of the control module, and the output terminals of the control terminal are connected with the power supply module.

The maximum voltage supplied by the power supply module to the lighting lamp is Vmax, and within the range of 0-Vmax, the brightness of the lighting lamp is proportional to the size of the power supply voltage; the human body detection module, height detection module, environmental humidity detection module and ambient light intensity detection The modules respectively transmit the detection signals to the control unit module in real time, and the control module determines the real-time power supply voltage V of the lighting lamp according to the detection signal, and sends the command of the voltage V to the power supply module, and the power supply module accepts the command to adjust the voltage V supplied to the lighting lamp in real time, Change the brightness of the lights.

Described human body detection module detects whether there are people around the smart desk lamp, and the range that the human body detection module can detect is set by the control module as the center of the smart desk lamp and a circle whose radius is Rmax; If the distance R is greater than Rmax, the voltage supplied by the power supply module to the lighting lamp is zero, and the lighting lamp is turned off; when the human body detection module detects that the distance R between the human body and the smart desk lamp is less than Rmax, the power supply module supplies power to the lighting lamp. The closer the distance to the smart desk lamp, the higher the voltage supplied by the power supply module to the lighting lamp, and the greater the brightness of the lighting lamp. When a human body is detected within the detection range, the lighting will automatically turn on.

The ambient light intensity detection module detects the light intensity of the surrounding environment of the intelligent desk lamp, and the threshold value of the ambient light intensity detection module is set by the control module to be Emax. When the light intensity E actually detected by the ambient light intensity detection is greater than Emax, the power supply module The voltage supplied to the lighting lamp is zero, and the lighting lamp is turned off; when the light intensity E actually detected by the ambient light intensity detection is less than Emax, the power supply module supplies power to the lighting lamp, and the lower the light intensity of the surrounding environment, the power supply module supplies the lighting lamp with The higher the voltage, the brighter the lamp.

The height detection module detects the vertical distance H from the intelligent desk lamp to the ceiling of the room where it is located, and the threshold value of the height detection module is set by the intelligent module to be Hmax; when the height H actually detected by the height detection module is greater than Hmax or when the ceiling is not detected, Let the detection height be equal to Hmax. At this time, the power supply module provides the maximum power supply voltage to the lighting lamp, and the lighting lamp is the brightest, and the lower the actual detection height is, the darker the lighting lamp is.

The ambient humidity detection module detects the air humidity of the surrounding environment of the intelligent desk lamp to S, and sets the threshold Smin through the control module. Generally speaking, general humidity will not affect the lighting effect of the desk lamp, but in a high humidity environment, such as in a steamy bathhouse or bathroom, the lighting effect of the desk lamp will also be limited, so the smart desk lamp of the present invention will detect the surrounding Humidity, intelligently adjust the brightness of the lighting in high humidity conditions.

Set the adjustment coefficient of the voltage supplied by the power supply module to the lighting lamp as W, W1 and W2 are the adjustment coefficients of the vertical distance from the smart desk lamp to the ceiling of the room where it is located, and satisfy 0<W1<1, 0<W2<1, W1+W2=1 , the adjustment coefficients W1 and W2 ensure that when H is small, the lighting lamp has a basic brightness.

The actual voltage supplied by the power supply module to the lighting lamp is V. When S is less than or equal to Smin, V=WVmax; when S is greater than Smin, V=[W+(1-W)(1-Smin/S)]Vmax.

As a further improvement, W1=0.7, W2=0.3, the adjustment coefficients W1 and W2 ensure that when H is small, the lighting lamp has a basic brightness.

As a further improvement, the human body detection module is an infrared induction sensor or an ultrasonic ranging sensor.

As a further improvement, the height detection module is an infrared induction sensor or an ultrasonic ranging sensor.

As a further improvement, the ambient light intensity detection module uses a photoresistor to acquire the ambient light intensity signal.

The present invention adopts above-mentioned technical scheme to have following obvious technical effect:

1. Through the use of human body detection module, height detection module, environmental humidity detection module and ambient light intensity detection module, the brightness of the lighting is controlled according to the actual detection signal, and the control is more precise.

2. The smart table lamp can intelligently adjust the brightness to achieve the purpose of energy saving and convenient use.

3. By setting the human body detection module, when the human body is detected within the detection range, the lighting will automatically turn on, which is more humane.
