Design and Implementation of Dynamic Regulation Function of Artificial Light Plant Lighting System

This paper focuses on the design and implementation of dynamic light regulation function of plant light system under intelligent plant culture control system based on industrial Internet of Things technology. The plant lighting system consists of several groups of LED light sources with different wavelengths, multi-channel NUMERICAL control power management IC and peripheral circuits, which together with other terminal equipment, terminal master control board, gateway, server, application end Web/APP, constitute the plant culture system. This project provides an equipment and control method for plant cultivation in a fully artificial environment. The method can achieve precise and dynamic control of the irradiance, photoperiod, and spectral distribution of the LED lighting system according to plant growth cycle information and user needs. The feature of this technology is that it can highly simulate the changing laws of the light environment in nature, and it can also customize the light formula according to plant preferences.
