Intermittent greenhouse light complementing system with automatic moving light source

Abstract

The invention discloses an intermittent greenhouse light complementing system with an automatic moving light source, and belongs to agricultural equipment. The light complementing system comprises a guide beam and a transmission device which are horizontally arranged in a greenhouse, and an electric light source device which is suspended on the guide beam and moves through a traveling wheel; the transmission device comprises a motor, two pulleys, and a transmission rope arranged between the two pulleys and connected with the electric light source device; sensors are arranged at two ends of the guide beam; and the sensors and the motor are in communication connection with a microprocessor respectively. The movable intermittent light complementing system ensures green and safe production of greenhouse plants and meets plant requirements; when light complement is not needed, the electric light source can be moved below the roof of the north slope, so that the plants are prevented from being shaded; the system is flexible in operation and convenient to control; and the system is compact in structure and convenient for detachment, movement and assembly, and is suitable for planting plants of different regions, different varieties and different greenhouse types.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to an intermittent supplementary light system for a greenhouse in which a light source automatically moves. Background technique [0002] Light not only provides the energy required for photosynthesis in higher plants, but also serves as a signal to regulate important plant life activities such as plant photomorphogenesis, photoperiod response, and internal circadian rhythm. In recent years, greenhouse cultivation has developed rapidly, and the regulation of light environment for plant growth has attracted extensive attention. In the Yangtze River Basin in the south, the period from November to before the Spring Festival is a critical period for the growth and development of greenhouse plants. The continuous rainy and little sunshine weather lasts for 10 to 15 days, or even more than 20 days each time, resulting in continuous insufficient light and serious impact on greenhouse plants. ...

Problems solved by technology

The above comparative documents creatively apply LEDs to plant cultivation devices, but still use fixed electric light sources for supplementary light, which has high cost investment and high energy consumption, and does not involve meeting the control needs of plants for the interval and variability of light.
