All-digital intelligent control system of LED plant light filling lamp

Abstract

The invention discloses a control system of an LED plant light filling lamp. The control system comprises an LED plant light filling lamp control box, intelligent drivers and LED plant light filling lamp holders. The light filling lamp control box includes a CPLD master control chip, an LCD display panel, a button array or a touch pad circuit, an RAM memory, and a ZIGEBB communication interface; and the control box is used for receiving information transmitted by the intelligent drivers and sending instructions to all the intelligent drivers based on an analysis. The intelligent drivers, which employ red light and blue light twin channel PWM digital driving, comprises CPLD driven control chips, temperature sensors, red and blue brightness sensors and ZIGEBB communication interfaces. Each of the intelligent driver collects brightness and temperature information around the plant and sends the information to the control box as well as receives an instruction from the control box, so that 256-level digital control with a arbitrary proportion of red light to blue light is realized. According to the invention, an all-digital intelligent regulation and control technology is utilized; therefore, when necessary, light filling can be carried out on various plants in same space; meanwhile, centralized control of plant light filling lamps in a large range can also be realized.

Description

technical field [0001] The invention relates to the field of LED intelligent lighting, in particular to an all-digital, intelligent LED plant supplementary light control system. Background technique [0002] LED plant fill light is a kind of lamp that uses red and blue LEDs as the light source, and uses light instead of sunlight to supplement the light of plants according to the sunlight required by the law of plant growth. Compared with traditional light sources, LED light sources have the advantages of pure light source, multiple wavelength types, energy saving and environmental protection, less heat generation and easy control. [0003] At present, most LED plant fill lights only have simple switch control for a single fill light, which is mainly realized manually. By adopting the method of fixed ratio of red and blue lamp beads, the method of supplementary light with fixed light intensity and fixed light quality is realized. If you want to achieve different R / B ratios ...

AI Technical Summary

Problems solved by technology

At the same time, factors such as external light conditions and ambient temperature are not considered, resulting in insufficient or excessive light supplementation for plants.

The existing LED plant supplementary light does not make full use of the advantages of digital, intelligent, and centralized control of LED light sources in design, and cannot meet the reasonable supplementary light requirements for plants.
