Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to a low-carbon planting greenhouse based on the Internet of Things. Background Art

[0002] During greenhouse cultivation, excessive light, especially at noon on sunny days, can easily cause photoinhibition of plants, which has an adverse effect on plant photosynthesis and growth and development. Traditional greenhouses lack effective means of photoinhibition control, and generally use shade nets to resist the damage of high temperature and strong light. However, the adjustment range of the shade nets is limited, and they cannot be finely controlled according to different plants and seasons. In addition, the shade nets convert solar energy into heat energy dissipation, resulting in energy waste. In addition, existing greenhouses mainly rely on external power supply for the operation of various equipment, which increases the cost of planting and pressure on the environment. At the same time, with the development of renewable energy, the application of solar energy in agricultural facilities needs to be further optimized and innovated to achieve efficient energy utilization and precise environmental control, and to ensure the healthy growth, high yield and high quality of plants.

[0045] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0046] like Figures 1 to 3 As shown, the present invention provides a low-carbon planting greenhouse based on the Internet of Things, comprising:

[0047] Greenhouse body 1. In practical applications, the greenhouse body can be a single greenhouse or a row of greenhouses;

[0048] Multiple rows of support plates 20 are arranged evenly spaced apart on the sun-facing surface 101 of the top of the greenhouse body through a rotating bracket 201. The angle between the extension direction of any row of support plates and the length direction of the greenhouse body is less than or equal to 90°. Any row of support plates includes at least two support plates 202 arranged in sequence longitudinally, and two adjacent support plates do not contact each other; wherein the relatively upper lateral edge of any support plate is pivotally connected to the pivot axis I on the rotating bracket so that any support plate is centered on the pivot axis I 203. The flippable setting is that the light-absorbing working position of any support plate is parallel to the sun-facing side of the greenhouse body, and the initial working position I of any support plate is that any support plate flips open at least 40° from the light-absorbing working position; multiple solar panels 204 are laid on the sun-facing side of multiple columns of support plates; multiple reflective panels I 205 are arranged on the back of multiple columns of support plates; multiple motors I are used to drive the pivot shafts I corresponding to the multiple columns of support plates, and the multiple motors I control the pivot shafts I and the multiple columns of support plates to be in the initial working position I;

[0049] A plurality of double-row guide grooves 30 are sequentially arranged in the gaps between the multiple columns of support plates on the sun-facing side of the greenhouse body, and the bottoms of the multiple double-row guide grooves are recessed toward the inside of the greenhouse body. The multiple double-row guide grooves are relatively lower than the multiple columns of support plates, and part of the guide grooves of any double-row guide groove extends to the bottom of any column of support plates adjacent thereto;

[0050] A plurality of reflective plates II 40, which are evenly arranged in a plurality of double-row guide grooves through a plurality of pivot shafts II 401 and can be flipped, and the plurality of pivot shafts II are evenly spaced and arranged longitudinally in sequence on the longitudinal beam 301 in the middle of the plurality of double-row guide grooves; and the reflective working position of any reflective plate II is inclined toward any reflective plate I that is relatively closest to it, so that at least 20% of the incident light of any reflective plate II is reflected to any reflective plate I that is relatively closest to it, and the initial working position II of any reflective plate II is nearly vertical to the ground; a plurality of micro motors II 60, which are respectively used to drive the plurality of pivot shafts II 50, and the plurality of micro motors II control the plurality of pivot shafts II and the plurality of reflective plates II to be in the initial working position II;

[0051] A plurality of light sensors 70 are evenly spaced and disposed in the greenhouse body;

[0052] A microcontroller 80 is disposed in the greenhouse body, and the microcontroller is communicatively connected with the plurality of motors I, the plurality of motors II and the plurality of light sensors;

[0053] The control center 90 includes a database in which a strong light threshold is pre-stored; a network communication module in communication connection with the microcontroller; a data processing and analysis module, which obtains multiple light intensity values ​​of multiple light sensors collected and stored in the microcontroller in real time through the network communication module, and synchronously compares the multiple light intensity values ​​with the strong light threshold one by one; if the light intensity values ​​that account for more than 50% of the multiple light intensity values ​​are all greater than the strong light threshold, the controller sends a shading instruction to the microcontroller through the network communication module, and the microcontroller receives the shading instruction and controls multiple motors I to drive the pivot shaft I to rotate, and synchronously drives the multiple columns of support plates to rotate from the initial working position I to the light absorption working position; at the same time, the microcontroller controls multiple micro motors II to drive multiple pivot shafts II to rotate, and synchronously drives multiple reflective plates II to rotate from the initial working position II to the reflective working position;

[0054] Afterwards, if more than 80% of the light intensity values ​​among the multiple light intensity values ​​are less than the strong light threshold, the controller sends a recovery instruction to the microcontroller through the network communication module. The microcontroller receives the recovery instruction and controls multiple motors I to drive the pivot shaft I to rotate, and synchronously drives the multiple columns of support plates to rotate from the light absorption working position to the initial working position I; at the same time, the microcontroller controls multiple micro motors II to drive multiple pivot shafts II to rotate, and synchronously drives multiple reflective plates II to rotate from the reflective working position to the initial working position II.

[0055] In this scheme, around noon, when the sun is shining directly and the temperature is too high, the multiple columns of support plates are in the light-absorbing working position, which can block part of the sunlight and reduce the exposure area of ​​the plants in the greenhouse body. At the same time, multiple solar panels can make full use of the blocked sunlight to convert light energy and improve the utilization rate of solar energy. At other times when the light is weak, the multiple columns of support plates are in the initial working position I, the blocked parts are opened, and the light projected on the back of the multiple columns of support plates is reflected into the greenhouse body, thereby increasing the brightness of the light in the greenhouse body, supplementing part of the light energy, improving the utilization rate of light energy during the day, effectively maintaining the photosynthetic rate, reducing the use of fill lights, and saving energy and reducing emissions. Right, when the temperature is too high due to direct sunlight, the incident light will be refracted and diverged after entering the arc-shaped groove wall of multiple double-row guide grooves, thereby reducing the light intensity in the area where multiple columns of support plates are not set, reducing light suppression, and at the same time, part of the light is refracted or diverged to the partial area blocked by the multiple columns of support plates, thereby improving the uniformity of light; with multiple reflective plates II in the reflective working position, the strong light incident into the multiple double-row guide grooves is reflected back onto the multiple reflective plates I, and then reflected by the multiple reflective plates I into the main body of the greenhouse, thereby further improving the uniformity of light, effectively improving the local excessive light intensity, and making full use of light energy, improving the light intensity in the main body of the greenhouse, and meeting the photosynthesis needs of plants;

[0056] With the microcontroller and multiple light sensors working with the control center, the working positions of multiple columns of support plates and multiple reflective plates II can be directly controlled according to the light intensity threshold, without manual intervention, to fully utilize light energy and effectively prevent light suppression and high temperature suppression;

[0057] In summary, the present invention provides a low-carbon planting greenhouse based on the Internet of Things, which can adjust the light intensity, light quality and lighting time in real time according to the actual lighting conditions in the greenhouse, effectively avoiding the growth damage of plants due to light inhibition, and improving the photosynthesis efficiency and photosynthetic product accumulation of plants, thereby promoting the healthy growth of plants, improving plant yield and quality, and increasing the economic benefits of agricultural production; in addition, it can also convert the blocked light energy into electrical energy to supply the power facilities in the low-carbon greenhouse while shading, thereby reducing carbon emissions, thereby providing an integrated agricultural and light complementary low-carbon greenhouse with a dynamic matching strategy.

[0061] If the light intensity values ​​that account for more than 60% of the multiple light intensity values ​​are all lower than the weak light threshold, the controller sends a fill light instruction II to the microcontroller through the network communication module, and the microcontroller receives the fill light instruction II and controls to turn on 50% to 60% of the fill lights that are evenly spaced among the multiple fill lights;

[0062] If more than 80% of the light intensity values ​​among the multiple light intensity values ​​are lower than the weak light threshold, the controller sends a fill light instruction I to the microcontroller through the network communication module, and the microcontroller receives the fill light instruction I and controls to turn on all the multiple fill lights;

[0063] Afterwards, if more than 70% of the light intensity values ​​among the multiple light intensity values ​​are higher than the low light threshold, the controller sends a light-off command to the microcontroller through the network communication module, and the microcontroller receives the light-off command and controls the turning off of multiple fill lights; or, the clock module sends a light-off command to the data processing and analysis module at the end of the fill light time period, and the microcontroller receives the light-off command and controls the turning off of multiple fill lights.

[0064] In this solution, through the effective cooperation of the clock module and the data processing and analysis module, the appropriate number of fill lights are turned on regularly and reasonably to meet the plant's fill light needs in a timely manner, scientifically and reasonably control the lighting duration, improve the plant's yield and quality, and increase the economic benefits of agricultural production.

In this solution, one column of support plates corresponds to one motor Ⅰ, and the working position of the column of support plates can be switched by the driving chain, which has a simple structure, is practical and convenient, and is easy to maintain.

After that, the light intensity of different areas can be controlled by exchanging data with the microcontroller and the control center through multiple light sensors set in different areas.
