An Adaptive Dimming and Energy Saving Control System

Abstract

The invention discloses a self-adaptive dimming energy-saving control system which comprises an illumination management unit, a light intensity detection unit, a temperature detection unit, a gas detection unit, a communication transmission unit and an intelligent control unit. The illumination management unit controls the on-off of illumination lamps and the operation of a sun shield through signals sent by the intelligent control unit. The light intensity detection unit senses the illumination intensity in a greenhouse through a photodiode, collects signals and feeds back the signals to theintelligent control unit. The temperature detection unit senses the internal temperature of the greenhouse through a temperature sensor, collects signals and feeds back the signals to the intelligentcontrol unit. The gas detection unit detects the concentration of CO2 in the greenhouse through a gas sensor, collects signals and feeds back the signals to the intelligent control unit. The communication transmission unit uploads the data to the cloud for storage. The intelligent control unit simply processes the data and sends an instruction to control each unit. According to the invention, self-adaptive dimming control is carried out according to the collected greenhouse data, energy conservation and emission reduction are realized, and the efficiency is improved.

Description

technical field [0001] The invention relates to a dimming and energy-saving technology, in particular to an adaptive dimming and energy-saving control system. Background technique [0002] With the continuous development of living standards, lighting devices are used in all walks of life, and people's living elements are inseparable from lighting devices. Existing dimming control systems are mostly used in people's daily life, and greenhouse planting actually needs to use this technology. [0003] Light is the main energy source for photosynthesis in plants. Plant photosynthesis is mainly affected by temperature, CO2 concentration, and light intensity. Reasonable light adjustment under conditions of too high or insufficient light intensity can increase the photosynthetic rate of plants. It is of great significance to develop an adaptive dimming system for greenhouses that meets the actual needs of agricultural production in my country. [0004] Most of the lighting techno...

Problems solved by technology

[0004] Most of the lighting technologies currently used have the problems of low light control accuracy and poor system stability.

Some achieve constant control of light source output brightness through PID control, but this supplementary light method has the problem of insufficient dynamic regulation mechanism, which is likely to cause insufficient supplementary light for greenhouse crops and energy waste; some real-time adjustment supplementary light output according to ambient temperature and light intensity amount, but does not take into account greenhouse CO 2 Influenced by the influence of the greenhouse light environment, it affects the accuracy of the regulation of the greenhouse light environment; some control strategies take into account multiple environmental factors such as the temperature, light, and gas in the greenhouse, but lack the upper computer control system, and cannot realize different dimming strategies for the dimming system. synchronous monitoring of
