Intelligent indoor light intensity control system and working method thereof

Abstract

An intelligent indoor light intensity control system and a working method thereof are used for automatically adjusting the light intensity in the home. The system can automatically cause an indoor light adjustment device and an indoor auxiliary lighting device to adjust the indoor light. The system adopts two adjusting devices which are jointly combined, and makes full use of external natural light, which enables the whole system to be high in adjusting speed and low in energy consumption. As the parameter, outdoor light intensity feedback, is added, and the adjustment process is reasonably arranged, redundant operation is avoided, and the work efficiency of the whole system is high. The invention further discloses a working method of the intelligent light intensity control system. According to the method, a control device is effectively adjusted and controlled according to the outdoor light intensity, the indoor light intensity and a set light intensity threshold so as to enable the indoor light intensity to reach the set threshold.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a Zigbee-based indoor light intensity intelligent control system and a working method. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for the comfort of the indoor environment. At the same time, due to the popularity of smart home equipment, indoor humidity, temperature, and light intensity adjustments are gradually becoming more intelligent. [0003] Light intensity control is an important factor to adjust the indoor living environment. For indoor light intensity adjustment technology, most of the indoor dimming control systems at the present stage use wired control, which brings great difficulties to the construction and wiring, and only for indoor lamps Adjustment, the adjustment method is single, the outdoor natural light is not fully utilized, and the ...

[0003] Light intensity control is an important factor to adjust the indoor living environment. For indoor light intensity adjustment technology, most of the indoor dimming control systems at the present stage use wired control, which brings great difficulties to the construction and wiring, and only for indoor lamps Adjustment, the adjustment method is single, the outdoor natural light is not fully utilized, and the purpose of energy saving and environmental protection is not achieved

Others adjust the indoor light intensity by installing motors and corresponding control circuits on the blinds and changing the inclination angle of the blinds. This adjustment method also has defects. When the outdoor light intensity is low, the user needs to turn on the indoor lighting. To increase the light intensity, it also increases more troubles for users, and the degree of intelligence is not high

[0004] In addition, the current light intensity adjustment method only sets a target value. When adjusting, it is completely adjusted to the target value, and the target value can only be exited. However, due to changes in the external weather, the light intensity indicator cannot be accurately stabilized at a value. Above, therefore, the entire adjustment device may be repeatedly adjusted due to some small changes in the external light intensity, or the device is repeatedly adjusted due to some interference, and the stability and immunity are not high
