Embodiment Construction

[0021] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] combine figure 1 , figure 2 and image 3 As shown, the executive module includes a supplementary light 1, a wire reel 2, a reel 3, a stepper motor 4, a worm gear transmission box 5, a steel rope 6, a pulley assembly 7, a bearing seat 8, a cultivation frame 9 and a cultivation bed 10 . The cultivation frame 9 is a unit body of the complete cultivation frame, and except the fill light 1, all other components are installed on the basis of the cultivation frame 9. Wherein the cultivation bed 10 is a soilless cultivation tank for planting plants 12, the bearing block 8 plays the role of supporting the winding shaft 3, and the pulley assembly 7 is used to change the direction of the wire rope 6. When the stepper motor 4 rotates, the motor main shaft drives the worm in the worm gear box 5 to rotate, and through a group of worm gea...

Abstract

The invention discloses a self-adaptive light supplementing system and method for a plant factory. The distance between a light supplementing lamp 1 and plants 12 planted on a culture bed 10 is measured through distance measuring sensors 11, and a stepping motor 4 is driven to operate so as to drive a winding shaft 3 to rotate, so that the light supplementing lamp 1 is driven by steel wires 6 winding round winders 2 to rise or fall; and meanwhile, the light supplementing system can measure and calculate the illumination intensity of a plant canopy through an illumination intensity sensor 13, and then the illumination intensity of the light supplementing lamp 1 is adjusted to be adapted to light intensity requirements of different crops. The method is simple and practical, and the illumination intensity of the light supplementing lamp 1 and the distance between the light supplementing lamp 1 and the plants 12 can be adjusted, so that only set values of system software are required to be changed, and then culture requirements of the different plants for the space and the illumination intensity can be met. The system and the method are applicable to light supplementing for culture of the various plants in the plant factory.

Description

technical field [0001] The invention relates to the field of artificial light sources for plant factories, in particular to an adaptive light supplement method and system for plant factories. Background technique [0002] The plant factory is the highest point in the development of facility agriculture. It can produce continuously for a year, can be produced under harsh environmental conditions, can produce safe and high-quality agricultural products without pesticides, and has light workload, easy operation and comfortable working environment. Etc. In recent years, the research on plant factories at home and abroad has attached great importance. However, due to the high initial construction costs of plant factories, their energy consumption (especially electric energy) is large, resulting in high operating costs, which have always limited the practical application of plant factories. [0003] At present, most plant factories are trying to use LEDs as artificial light sour...
