Problems solved by technology

Although this method can reduce building electricity consumption to a certain extent, it ignores the problem of indoor lighting comfort.
[0006] 2. Traditional lighting control method
Although this method realizes the automatic dimming function, it is still in the stage of unified control and unified adjustment, and the indoor dimming effect cannot guarantee the comfort and uniformity of indoor illuminance.

Embodiment 1

[0083] see figure 1 and figure 2 Shown is an adaptive indoor dimming method based on differential evolution algorithm described in this application, including:

[0084] Step 101, the DALI interface dimming unit communicates with M infrared illuminance meters in the room through the RS485 bus, reads the illuminance of the current environment through the infrared illuminance meters, and judges the usage scene according to the illuminance of the current environment: when the DALI interface When the infrared illuminance meter monitors that the predetermined time t is exceeded, and there are more than a predetermined number of infrared illuminance meters that do not detect human body signals, it is judged that the current use scene is a special use scene, otherwise it is a normal use scene;

[0085] Step 102: When it is judged that the use scene is a normal use scene, it means that the current room needs to provide overall lighting, and the DALI interface dimming unit executes th...

Embodiment 2

[0114] The present invention also provides an adaptive indoor dimming system based on a differential evolution algorithm, which is characterized in that it includes:

[0115] DALI interface dimming unit, M infrared light meters and multiple LED lamps,

[0116] The DALI interface dimming unit is connected to the N infrared illuminance meters through the RS485 bus,

[0117] The DALI interface dimming unit is used to communicate with the N infrared illuminance meters in the room through the RS485 bus, communicate with the LED lamps through the DALI bus, read the illuminance of the current environment through the infrared illuminance meter, and illuminance judgment usage scenario: when the DALI interface is monitored by the infrared illuminance meter for more than a predetermined time t, and there are more than a predetermined number of infrared illuminance meters that do not detect human body signals, then the current usage scenario is judged as Special usage scenarios, otherwis...

Embodiment 3

[0141] Application examples of the adaptive indoor dimming method and system based on the differential evolution algorithm of the present invention are provided below.

[0142] see Figure 4 , taking the classroom as an example, establish the position model of classroom lamps and sensors, and install five infrared illumination sensors in the classroom according to the detection sector area of ​​the infrared illumination sensor.

[0143] see figure 2 After the system initialization is completed, first read the current indoor illuminance value collected by the infrared illuminance meter, and at the same time collect the infrared signal of the human body detected by the infrared sensor, and judge the current indoor scene through fuzzy judgment. Judgment method, taking a campus classroom as an example, the system collects the detection status of 5 infrared sensors in real time. When 3 or more infrared sensors detect no human infrared signals in their respective areas for more th...

Abstract

The invention discloses a differential evolution algorithm based adaptive indoor dimming method and system. The adaptive indoor dimming method comprises the steps that a DALI interface dimming unit is in communication with M infrared illuminometers indoors through an RS485 bus, and is in communication with LED lamps through a DALI bus; the illumination of the current environment is read by the illuminometers; the usage scenario is determined according to the illumination of the current environment: when the DALI interface detects that illuminometers with the number which is greater than a predetermined number n do not detect human body signals when the detecting time exceeds a predetermined time t through the illuminometers, the current usage scenario is determined to be a special usage scenario; or otherwise, the current usage scenario is determined to be a normal usage scenario; when the usage scenario is determined to be the special usage scenario, it is proves that certain illumination is needed to be applied to the current indoor; and the DALI interface dimming unit executes the differential evolution algorithm to obtain an optimal lamp luminance combination so as to performing dimming on the special region to realize the predetermined illumination value.

Description

technical field [0001] The present application relates to the technical field of indoor dimming and green energy saving, in particular, to an adaptive indoor dimming method and system based on a differential evolution algorithm. Background technique [0002] With the rapid development of intelligent control technology, intelligence has penetrated into all aspects of our lives and has gradually become an indispensable part of the national economy. Intelligent building energy saving is proposed under such conditions. Some developed countries in foreign countries began to pay attention to the research on intelligent buildings as early as the 1970s. Today, they have been able to incorporate natural lighting, indoor lighting, air conditioning, etc. into the intelligent control network, and realized the control It can be said that the coordination of the Internet of Things has been realized, and good results have been achieved in energy saving. [0003] At present, there are the...
