Intelligent plant supplementary lighting method and device

Abstract

The invention relates to an intelligent plant supplementary lighting method. The method comprises the following steps: setting a red light threshold and a blue light threshold according to the demand of a plant on red light and blue light in each growth stage; detecting the intensities of the red light and the blue light in the growing environment of the plant; comparing the intensities with the corresponding red light threshold and blue light threshold to judge whether supplementary lighting is required and determine the accurate volume of the supplementary lighting; if the supplementary lighting is required, calculating the input current of a corresponding supplementary lighting set according to the volume of the supplementary lighting, so as to accurately control the intensity of the supplementary lighting set and realize intelligent and accurate supplementary lighting on demand, and if the supplementary lighting is not required, turning off the supplementary lighting set. The invention also provides a device realizing the method. By utilizing the supplementary lighting method and device in the invention, quantitative demand supplementary lighting by wavelength can be carried out on the plant according to the characteristics in different growth stage of the plant.

Description

technical field [0001] The invention belongs to the field of agricultural modernization, relates to the artificial control of the plant growth process, and in particular relates to a method and equipment for intelligent light supplementation of plants. Background technique [0002] With the development of science and technology, artificial lighting technology has been proposed and widely researched and utilized. In the past plant supplementary light system, the supplementary light sources mainly include incandescent lamps, halogen tungsten lamps, high-pressure mercury fluorescent lamps, high-pressure sodium lamps, etc. These light sources have the defect of unsatisfactory spectral matching in the application of plant supplementary light, and the light source emits white light spectrum. Or linear spectral lines, which can be absorbed by plants are only the light of individual bands, and the light of other bands is wasted, which is not energy-saving; in addition, these light s...

Problems solved by technology

Among them, the first two methods are easy to use, but due to the influence of human experience and external environment, the system flexibility is poor and the fill light effect is very different.

The third mode adopts the mode of automatic detection and automatic supplementary light, but because the existing system adopts the method of fixed red and blue light intensity and light intensity ratio, it does not consider the difference in the ratio of red and blue light required by different plants at different stages. There are still some problems with the accuracy of light
