Abstract

The invention discloses an indoor illumination control system and method based on outdoor illumination sampling. The indoor illumination control system comprises an outdoor illumination sampling module, an illumination attenuation calculating module, a supplementary lighting calculating module, a dimming quantity calculating module and a dimming drive circuit, wherein the outdoor illumination sampling module is used for collecting outdoor sunlight information; the illumination attenuation calculating module is used for calculating the actual sunshine amount of an illumination space in which each indoor lamp is so as to calculate the supplementary lighting amount of the lamps for supplementary lighting illumination; the supplementary lighting calculating module is used for calculating the supplementary lighting amount required for each lamp according to the actual sunshine amount of the illumination space in which each indoor lamp is which is calculated and obtained by an illumination attenuation model and according to required indoor target illumination; the dimming quantity calculating module is used for calculating output dimming quantity of each lamp required for supplementary lighting illumination according to the supplementary lighting amount of each lamp required in the illumination space calculated and obtained by the supplementary lighting calculating module; the dimming drive circuit is used for carrying out illumination power drive output for each lamp respectively according to the output dimming quantity of each lamp required for supplementary lighting illumination calculated and obtained by the supplementary lighting calculating module.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to an indoor lighting control system and method based on outdoor illuminance sampling. Background technique [0002] The lighting control system is the hardware and software structure for switching and dimming control of lamps and lanterns according to the needs of use and in combination with factors such as sunlight, time, and human induction. [0003] At present, the energy problem is a major problem facing the sustainable development of our society. At present, all parts of the country are facing various problems caused by power shortages. While indoor lighting brings convenience to each of us, it also consumes a lot of energy. of electric energy. The purpose of indoor lighting is to meet people's work and living needs. At present, most buildings in China are still using traditional lighting control methods. In quite a lot of cases, they are doing useless work and cannot meet the...
