Illumination control system and method for intelligent plant factory with multi-color LEDs

Abstract

The invention discloses an illumination control system and method for an intelligent plant factory with multi-color LEDs. The light-emitting power proportions of a plurality of light colors are calculated by detecting the light-emitting power of LED plant lamps with different light colors, calculation is carried out according to the light-emitting power proportions of the LED plant lamps with various light colors and the preset reference light-emitting power proportion, and an illumination control signal is sent out and controls the light-emitting power of the LED plant lamps with different light colors, and the light-emitting power proportions of the light colors are matched with the reference light-emitting power proportion so that the requirement for illumination of different growing stages of plants can be met. Due to the fact that the light-emitting power of the LED plant lamps with the light colors is continuously detected online in real time, the light-emitting power of the LED plant lamps with the light colors is adjusted according to the requirement for illumination of different growing stages of the plants, the plants in the plant factory can be in an optimal growing state, the energy utilization rate of the plant factory is increased, and energy resources are saved.

Description

technical field [0001] The invention relates to the technical field of plant factories, in particular to an illumination control system and method for an intelligent plant factory using multi-color LEDs. Background technique [0002] The plant factory integrates biotechnology, modern optoelectronic technology, information technology, mechanical engineering, artificial environment control and other high technologies. It is recognized as the most advanced development stage of agriculture in the world. It is considered to be an effective way to solve population, resource and environmental problems in the future. technical means. Hundreds of plant factories abroad, especially in Europe, America, Japan, and South Korea, have been put into operation, and they have begun to make profits by planting cash crops such as ginseng and flowers. Seasonal vegetables such as lettuce and tomatoes grown in plant factories are becoming more and more popular and have appeared in many supermarke...

AI Technical Summary

Problems solved by technology

[0005] At present, the power ratio of red light and blue light in plant factories is fixed, but in fact different types of plants require different light intensities and ratios at different growth stages, resulting in plants in plant factories not being in the best growth state , and cannot perform continuous and real-time online light monitoring and light control for red, blue and other polychromatic lights according to the growth status of plants
