Problems solved by technology

However, the current lighting control system is currently difficult to effectively control the automatic sensing of external light. The main reason is that the current control system cannot distinguish whether the change in light intensity is caused by natural light or unnatural light.
Unnatural light is usually caused by external interference—external interference includes the interference generated when there is a sudden block around the lamp, the interference generated when someone deliberately blocks the lamp, the reflection interference caused by adding other light sources near the lamp, and the It is difficult to achieve the method of automatically sensing the external light to control the light switch due to its own reflection interference and so on.

Embodiment 1

[0023] This embodiment refers to a natural light control light switch method with anti-unnatural light interference, which is used on decorative lights or garden lights, and its control steps are mainly:

[0024] 1) First set the parameters of the internal control mechanism of the lamp according to the requirements: set the minimum light intensity to turn on the light to 80 LUX, the unit time to 20 s, the threshold to 10 LUX / 20s, and the effective light to turn off the light to 200 LUX.

[0025] The unit time mentioned therein refers to the interval time between each sensing operation of the photosensitive sensor set by the control mechanism;

[0026] The minimum light intensity turn-on value refers to the critical value set by the control mechanism to theoretically perform the turn-on or turn-off operation without unnatural light interference;

[0027] The threshold value refers to the judging value set by the control mechanism to distinguish the natural light intensity from ...

Embodiment 2

[0047] This embodiment refers to a natural light control light switch method with anti-unnatural light interference, which is used on indoor lights, and its control method and steps are the same as in embodiment 1. The difference between it and embodiment 1 is: the internal control of the lamp The parameters set by the mechanism are: set the minimum light intensity to turn on the light as 50 LUX, the unit time as 10 s, the threshold as 5 LUX / 20s, and the effective light to turn off the light as 100 LUX.

Embodiment 3

[0049] This embodiment refers to a natural light control light switch method with anti-unnatural light interference, which is used on outdoor street lamps. Its control method and steps are the same as in embodiment 1, and the difference between it and embodiment 1 is: the internal control of the lamp The parameters set by the mechanism are as follows: set the minimum light intensity to turn on the light to 120LUX, the unit time to 1min, the threshold to 80LUX / 20s, and the effective light to turn off the light to 400 LUX.

Abstract

The invention discloses a lamp switch natural light control method with non-natural light interference resistance. The method is characterized in that: by utilizing characteristics that a light intensity value of natural light changes slowly with time change and shows a gradually change trend while a light intensity value of non-natural light changes suddenly and shows no rule with time change, alight intensity value of external light and light intensity variation of light in adjacent unit time are taken as a basis of distinguishing natural light from non-natural light to carry out determination, analysis and processing, thus natural light is utilized to control a lamp switch. According to the invention, interference light intensity of natural light and light intensity of non-natural light are distinguished, accurate switch on and off functions of a lamp are realized, and efficacies of intelligent control, safety and environmental protection are achieved.

Description

technical field [0001] The invention relates to a method for controlling a light switch by natural light with anti-unnatural light interference. Background technique [0002] At present, the indoor and outdoor lights used in the market can only be turned on or off through the switch system artificially; with the improvement of the current degree of automation, people also urgently hope to automatically turn on the lights by sensing the intensity of the external light Or the purpose of turning off the lights can not only achieve the purpose of convenience and peace of mind, but also avoid the waste of power resources caused by forgetting to turn off the lights, and save costs, especially for street lights or decorative lights. The light control system of the existing lamp mainly includes a photosensitive sensor, a controller and an actuator; the photosensitive sensor is connected to the input end of the controller, and the actuator is connected to the output end of the co...
