Intelligent greenhouse light supplementing system

Abstract

The invention discloses an intelligent greenhouse light supplementing system which comprises a bearing reversing mechanism and a movable light supplementing mechanism, and the front end of the bearingreversing mechanism is movably connected with the movable light supplementing mechanism. According to the system, an illumination sensor is fixedly arranged at the upper end of a main lamp box, and the output end of a stepping motor is connected with a light reflecting and refracting plate through a rotating rod, so that when plants are cultivated, the indoor illumination intensity can be monitored in real time through the illumination sensor, and if the illumination intensity is sufficient, the stepping motor is started to drive the rotating rod and drive the light reflecting and refractingplate to rotate to a proper angle, and the light reflecting and refracting plate is used for refracting incident light to the plants to facilitate photosynthesis and promote growth of the plants, andat the same time, if the illumination intensity sensed by the illumination sensor is lower than a preset illumination threshold value, the main lamp box can be synchronously started, primary light supplementing lamp beads and secondary light supplementing lamp beads are used for supplementing light for indoor plants, and compared with a common light supplementing device, the intelligent greenhouselight supplementing system is more intelligent and saves more energy.

Description

technical field [0001] The invention relates to the technical field of greenhouse control and supplementary light devices, in particular to a greenhouse intelligent supplementary light system. Background technique [0002] Light is one of the most important environmental factors affecting plant growth and development, and is the energy source for plant photosynthesis. Greenhouses can overcome the influence of seasons and climate changes on plant growth to a certain extent. Most of the plants in the greenhouse grow out of season, and the light environment cannot meet the growth needs. The supplementary light in the greenhouse should conform to the law of plant growth in terms of illuminance and light quality. For example, red light can promote the growth of stems and induce germination, while blue light is the best for seedling growth. At present, most of the supplementary light in greenhouses needs to be done manually, and the light source with fixed wavelength is used to ...
