Light control-based energy-saving system and method for classroom

Abstract

The invention provides a light control-based energy-saving system and method for a classroom. The light control-based energy-saving system comprises a central processor, a human body detection module, a photosensitive circuit module, a key module and a setting module, wherein the central processor is connected with the human body detection module, the photosensitive circuit module, the key module and the setting module respectively; a classroom lighting mode is set into a general mode, a self-study energy-saving mode and a class slide show mode; on and off of lighting equipment are controlled in the general mode according to the intensity, of ambient light in the classroom, obtained by the photosensitive circuit module and the personnel distribution obtained by the human body detection module; on and off of the lighting equipment are controlled in the self-study energy-saving mode according to the personnel distribution obtained by the human body detection module; and all pieces of lighting equipment are closed in the class slide show mode. According to the light control-based energy-saving system and method for the classroom provided by the invention, different lighting strategies are customized according to different lighting modes, so that subjective power waste caused by no intention is avoided.

Description

technical field [0001] The invention relates to a power saving system and method, in particular to a classroom power saving system and method based on lighting control. Background technique [0002] With the rapid development of social economy and increasing electricity consumption, energy shortage has become a problem faced by the whole world, and this problem is especially serious for our country. With the expansion of college enrollment and classroom expansion, the demand for classroom lighting has further increased. Because the management of classroom lighting is not in place, it will cause a huge waste of electric energy. Therefore, how to improve classroom electricity efficiency has become an urgent problem to be solved. [0003] In the prior art, there have been various technical solutions for classroom electricity control. For example, the Chinese invention patent with the application number 201410531955.X and the invention name "Intelligent Control Device for Cla...
