Problems solved by technology

However, due to the heavy weight of the sunshade net itself, the number is generally large, and the labor force of farmers has greatly increased.
And because the sunshade net is inconvenient to move for protection, it will cause erosion such as rainwater, shorten the service life and increase the cost

Embodiment 1

[0038]The infrared range finder 21 measures the height of vegetables in the greenhouse, and transmits the data to the single-chip microcomputer 5, the single-chip microcomputer 5 starts the motor c, the output end of the motor c is wound with one end of the traction rope 17, and the other end of the traction rope 17 is bypassed by the fixed pulley 16 And tie the temperature sensor 18, the motor c starts to pull the temperature sensor 18 to be high with the vegetable leaf surface, in the time period from 8:00 am to 5:00 pm at the specified time, the temperature sensor 18, the air humidity sensor 19 and the light intensity The sensor 20 collects data in real time and transmits it to the single-chip microcomputer 5. When the value reaches the preset value range, the single-chip microcomputer 5 starts the motor a7 and the motor b14, and the output end of the motor b14 is connected to one end of the part of the rotatable barrel-shaped protective shell. And turn a certain angle to op...

Abstract

The invention provides a full-automatic sunshade net rolling protection device for a greenhouse. The device comprises a main power supply, a sunshade net automatic rolling device, a sunshade net automatic protection device, a temperature acquisition device, a single chip microcomputer, a manual control device and a data acquisition device. The manual control device is connected with the main power supply. The sunshade net automatic rolling device is connected with the manual control device, and the single chip microcomputer is connected with the sunshade net automatic rolling device. The sunshade net automatic protection device and the temperature acquisition device are connected with the single chip microcomputer. The data acquisition device is connected with the single chip microcomputer. According to the device, required data are continuously detected through the data acquisition device within the specified time, the data are processed by the single chip microcomputer, and when the data reach a preset value, a motor is automatically controlled to rotate, so that the sunshade net is pulled out, full automation of rolling work is achieved, labor force is greatly reduced, and certain illumination time is guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural greenhouses, in particular to a fully automatic sunshade net winding protection device for greenhouses. Background technique [0002] Agricultural greenhouses play an indispensable role in contemporary agricultural planting due to their functional advantages such as increasing temperature, increasing carbon dioxide concentration in the surrounding environment, and preventing rain erosion or excessive rainwater irrigation, so that it is widely used. However, when the outdoor temperature is too high, the photosynthesis of crops will be weakened, and even the seedlings will be burned due to water evaporation, so more and more farmers use sunshade nets to cool down and shade. However, due to the heavy weight of the sunshade net itself, the number is generally large, and the labor force of farmers has greatly increased. And because the sunshade net is inconvenient to move and protect, it will cause erosion...
