Adaptive indoor dimming method and system based on differential evolution algorithm

Abstract

The application discloses an adaptive indoor dimming method and system based on a differential evolution algorithm. The method includes: a DALI interface dimming unit communicates with M indoor infrared illuminance meters through an RS485 bus, and communicates with LED lamps through the DALI bus , read the illuminance of the current environment through the infrared illuminance meter, and judge the use scene according to the illuminance of the current environment: when the DALI interface monitors the infrared illuminance meter to exceed the predetermined time t, there are more than a predetermined number n When the infrared illuminometer does not detect a human body signal, it is judged that the current use scene is a special use scene, otherwise it is a normal use scene; when it is judged that the use scene is a special use scene, it means that the current indoor needs to provide partial lighting, the DALI The interface dimming unit executes the differential evolution algorithm to obtain the optimal combination of lamp brightness, and dimming the specific area to the preset illuminance 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...

AI Technical Summary

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.
