Intelligent LEDs lamp holder adjusting and controlling system for plant factory cultivation frame

Abstract

Provided is an intelligent LEDs lamp holder adjusting and controlling system for a plant factory cultivation frame. The LEDs lamp holder adjusting and controlling system comprises a drive set, a transmission set, a lamp holder set, an ultrasonic distance measuring sensor (10), a system controller, cultivation frames (12) and cultivation grooves (11). The drive set comprises a stepping motor (1), a rotary drum (2), rotary drum supporting bearings (13) and rotary drum shafts (14). The transmission set comprises a left flexible suspension wire rope (3), a right flexible suspension wire rope (4), a left supporting idler wheel (5), a right supporting idler wheel (6) and supporting idler wheel supports (7). The lamp holder set comprises adjustable lamp holder suspension locking devices (8), LEDs lamp holders (9) and suspension locking device installing holes (15). The ultrasonic distance measuring sensor is used for detecting the heights of lamp plates and canopies of cultivation plants so that positions of the lamp plates can be automatically adjusted along with change of the growing heights of the plants, and reasonable heights of light sources of the lamp plates and the canopies of the plants can be conveniently kept.

Description

technical field [0001] The invention relates to the fields of intelligent agricultural equipment and electromechanical automatic control, in particular to a system for automatically adjusting the height of multi-layered light stands for cultivation racks in plant factories by using ultrasonic ranging technology and motor transmission control technology. Background technique [0002] The plant factory is an agricultural system that realizes the annual continuous production of crops through high-precision environmental control, that is, the use of computers to control the temperature, humidity, light, CO 2 The concentration and nutrient solution and other environmental conditions are automatically controlled, so that the plant growth in the facility is not or rarely affected by natural conditions. Labor-saving production. The plant factory can realize the production of vegetables, flowers, fruits, medicinal materials, edible fungi and some food crops, etc. It is an intensive t...

AI Technical Summary

Problems solved by technology

[0006] The present invention is aimed at the inconvenience of manual adjustment of the distance between the LEDs light source and the crop canopy, the inability to automatically adjust the distance and the inaccurate adjustment accuracy during actual operation, and develops a motor control, transmission technology, and ultrasonic ranging sensing technology. Intelligent LEDs light stand control device and control system with embedded control technology to realize precise and automatic control of the distance between LEDs light source and crop canopy
