Especially in the low-lying areas of the river valleys in the Sichuan Road area, almost every year suffers from late frost damage, causing heavy losses to fruit farmers, seriously affecting the enthusiasm of fruit farmers for production, and becoming one of the bottlenecks restricting the local industrial development. When the late spring frost occurs in spring, technical measures such as covering the shed in advance and heating and increasing the temperature inside the shed are adopted to reduce the harm of slight frost. After the frost prevention period ends, the film can be rolled up and the near-open-air management form can be adopted. The antifreeze greenhouse does not occupy space and does not affect the growth of the tree body and the orchard operation.

[0043] The following will further explain and describe the anti-freezing greenhouse provided by the embodiment of the present invention through optional embodiments.

[0044] It should be noted that the component of the first truss 11 along the first direction extends and contracts along the width direction of the greenhouse main body, and the component of the first truss 11 along the second direction extends and contracts along the height direction of the greenhouse main body. Similarly, the component of the second truss 12 along the first direction extends and contracts along the width direction of the greenhouse main body, and the component of the second truss 12 along the second direction extends and contracts along the height direction of the greenhouse main body.

[0045] The greenhouse main body provided by the embodiment of the present invention is provided with a ventilation walking passage at the top of the main truss, and ventilation openings 101 are provided at both ends of the greenhouse main body.

The ventilation openings 101 are provided at both ends of the greenhouse main body, and waterproof covers are provided at the ventilation openings 101 to prevent external rainwater from entering the greenhouse main body.

[0046] The first direction in the embodiments of the present invention can be understood as telescoping along the width direction of the greenhouse main body. When the first truss 11 and the second truss 12 move towards each other in the first direction, the first truss 11 and the second truss 12 are connected. In the embodiments of the present invention, magnets are arranged at the connection of the first truss 11 and the second truss 12. When the first truss 11 and the second truss 12 meet, they are attracted and connected by the magnets. When it is necessary to disconnect the first truss 11 and the second truss 12, the magnets are electrified, and the attraction between the first truss 11 and the second truss 12 is lacking and they are disconnected. When the first truss 11 and the second truss 12 move in the second direction, the first truss 11 and the second truss 12 rise or fall. Here, the second direction can be understood as the direction perpendicular to the ground. The embodiments of the present invention can control the rise or fall of the first truss 11 according to actual needs, or independently control the rise or fall of the second truss 12, or control the first truss 11 and the second truss 12 to rise or fall simultaneously. That is, the greenhouse provided by the embodiments of the present invention can control at least one truss (the first truss 11 or the second truss 12, or the first truss 11 and the second truss 12) to rise or fall to facilitate the lighting, wind resistance, temperature and humidity, etc. requirements of the greenhouse. The volume of the greenhouse provided by the embodiments of the present invention is reduced by 60% after contraction.

[0047] The heating component provided by the embodiments of the present invention can be a heating wire wound around the first truss 11 and the second truss 12, and the heating temperature is controlled by controlling the power supply of the heating wire.

[0048] In an alternative embodiment, the first truss 11 includes a first sliding sleeve 111, a first sliding rod 112 and a first motor 113. The first sliding sleeve 111 and the first sliding rod 112 are sleeved, and the first motor 113 is used to drive the first sliding rod 112 to move.

[0049] The second truss 12 includes a second sliding sleeve, a second sliding rod and a second motor. The second sliding sleeve and the second sliding rod are sleeved, and the second motor is used to drive the second sliding rod to move. It should be noted that the structural diagram of the second truss 12 is similar to that of the second truss 11, and the embodiments of the present invention do not illustrate this. The specific structural diagram of the second truss 12 can be referred to Figure 2 in the structural diagram of the first truss 11.

[0050] The first motor 113 and the second motor in the embodiments of the present invention can operate independently, that is, the movements of the first truss 11 and the second truss 12 can be controlled separately, improving the practical application ability of the greenhouse.

[0051] In an alternative embodiment, the first truss 11 and the second truss 12 are trusses with a preset radian, and one end with a radian of the first truss 11 and the second truss 12 is connected.

[0052] In an alternative embodiment, the film assembly 2 includes a first partition film, a first film rolling motor 23, a second partition film, and a second film rolling motor. One end of the first partition film is connected to the first film rolling motor 23, and the other end covers the first truss 11. One end of the second partition film is connected to the second film rolling motor, and the other end covers the second truss 12.

[0053] In the embodiment of the present invention, the first partition film and the second partition film are provided separately. The first partition film is disposed on the first truss 11, and the second partition film is disposed on the second truss 12. The first partition film or the second partition film can be withdrawn and rolled up according to actual needs, or one of the partition films (the first partition film or the second partition film) can be withdrawn and rolled up or covered on the greenhouse.

[0054] Exemplarily, the user can roll up the first partition film and unfold the second partition film according to actual needs. For example, according to the lighting requirement, the first partition film facing the sun can be rolled up to provide natural lighting for the greenhouse, and the second partition film facing away from the sun can be covered to keep the greenhouse warm, which not only satisfies the natural lighting of the greenhouse but also prevents the temperature inside the greenhouse from being lost due to light leakage.

[0055] Furthermore, the film assembly 2 further includes a first film rolling shaft 21, a first film rolling hub 22, a second film rolling shaft, and a second film rolling hub 22. The first film rolling shaft 21 is rotatably connected to the first film rolling hub 22, and the first film rolling shaft 21 is connected to the first film rolling motor 23. The film of the first film rolling partition is sleeved on the first film rolling shaft 21. By rotating the first film rolling motor 23, the first film rolling shaft 21 is driven to rotate, thereby realizing the unfolding and releasing of the film of the first film rolling partition.

[0056] The second film rolling shaft is rotatably connected to the second film rolling hub. The second film rolling shaft is connected to the second film rolling motor. The film of the second film rolling partition is sleeved on the second film rolling shaft. By rotating the second film rolling motor, the second film rolling shaft is driven to rotate, thereby realizing the unfolding and releasing of the film of the second film rolling partition. It should be noted that the structural diagrams of the second film rolling shaft and the second film rolling hub are similar, and they are not illustrated in the embodiment of the present invention. The specific structural diagrams of the second film rolling shaft and the second film rolling hub can be referred to Figure 3 in the structural diagram of the first truss 11.

[0057] Furthermore, when the first partition film and the second partition film are unfolded, the films can be manually unfolded. The first partition film and the second partition film are attracted and adhered by magnetic strips. When the film needs to be removed, the power supply to the magnetic strips is cut off, and the first reel motor and the second reel motor are controlled to rotate to recover the first partition film and the second partition film.

[0058] In an alternative embodiment, the first partition film and the second partition film are in a Z-shaped folded state, and after the first partition film and the second partition film are unfolded, they are connected by a magnetic sealing strip.

[0059] The first partition film and the second partition film being in a Z-shaped folded state can reduce the floor space occupied by the film. Further, the first partition film and the second partition film can adopt a segmented folding film, which is driven by a linear stepping motor, and the unfolding speed can be adjusted, for example, it can be 0.12 m / s - 2 m / s.

[0060] In an alternative embodiment, the wind-resistant anchoring assembly 3 includes: a base 31, a cylinder barrel 32, a cylinder head 33, a piston 34, and an anchoring rod 35; the cylinder barrel 32 and the cylinder head 33 are located on the base 31, the cylinder barrel 32 and the cylinder head 33 together form a closed oil cavity to push the anchoring rod 35 to move, and the anchoring rod 35 is connected to the main truss.

[0061] The wind-resistant anchoring assemblies 3 are deployed at the four corners of the shed body of the greenhouse of the present invention. Exemplarily, when the wind speed > 5 levels, it automatically inserts into the ground by 1.5 m, and the anchoring depth is real-time fed back through a pressure sensor, and the depth of the wind-resistant anchoring assembly 3 is adjusted based on the wind speed.

[0062] In an alternative embodiment, the film assembly 2 further includes a dust-proof cover plate, which is arranged at the bottom of the main truss, and when the partition film is folded and retracted, the dust-proof cover plate covers the partition film.

[0063] The embodiment of the present invention also provides a control method for an anti-freezing greenhouse, including: obtaining the ambient temperature and the internal temperature of the anti-freezing greenhouse.

[0064] Based on the ambient temperature and the internal temperature, control the heating component to heat the anti-freezing greenhouse. Exemplarily, when the ambient temperature and the internal temperature of the greenhouse are relatively low, the heating component can be controlled to heat the anti-freezing greenhouse, and when the ambient temperature and the internal temperature of the greenhouse are relatively low, the heating of the anti-freezing greenhouse by the heating component can be stopped.

[0065] Obtain the ambient wind speed of the anti-freezing greenhouse, and based on the ambient wind speed of the anti-freezing greenhouse, control the folding and retraction or unfolding and covering of the partition film, or control the first truss 11 and the second truss 12 to move along the first direction or the second direction.

[0066] In an alternative embodiment, when the wind speed > 8 m / s, start step-by-step film retraction: when the wind speed is 8 - 10 m / s, retract the partition film by 50%; when the wind speed is 10 - 12 m / s, retract the partition film by 30%; when the wind speed > 12 m / s, lock the anti-freezing greenhouse through the wind-resistant anchoring assembly 3 and enter the wind-resistant mode.

[0067] On the other hand, an embodiment of the present invention provides an antifreeze greenhouse control system, including a readable storage medium, on which the above-mentioned method is stored.

[0068] The antifreeze greenhouse provided by the embodiment of the present invention further includes a software control system. The software control system includes a frost prediction model, which can predict whether frost occurs in the area where the greenhouse is located, and then better control the heating component, the film component 2 and the wind-resistant anchoring component 3 of the greenhouse to act together to protect the safe operation of the greenhouse.

[0069] Further, the software control system of the embodiment of the present invention includes obtaining real-time meteorological data (such as temperature, humidity, dew point, wind speed) of the area where the greenhouse is located; 72-hour regional microclimate forecast. Exemplarily, data from the meteorological bureau can be accessed through an API; a historical frost event database, which can be obtained through a spatio-temporal distribution map.

[0070] Use an LSTM neural network to establish a time series prediction model. The input time window is the environmental data of the previous 6 hours, and the output is the frost probability in the next 3 hours; fuse a random forest classifier to classify the risk level during the low-temperature sensitive period (such as the flowering period) (for example, it can be divided into levels I-IV). And based on the classified risk, trigger a protection preparation instruction 2 hours in advance, and then control the coordinated operation of each structure of the greenhouse. Further, when the predicted frost probability > 70%: the film can be deployed to the full coverage state 1 hour in advance; and the preheating program is started to make the temperature gradient in the greenhouse ≤ 2°C / m. When the temperature drops suddenly (for example, ΔT > 5°C / 10 min): start the heating component in stages (preferably using the electricity stored during the low-valley electricity price period); turn on the rotating sprinkler to form air disturbance and eliminate the cold lake effect.

[0071] Application Example

Compared with traditional greenhouses: Wind resistance: successfully withstood a 10-level gust of wind (the damage rate of traditional greenhouses is 100%); - Frost prevention effect: the frost loss rate during the flowering period dropped from 32% to 5%; Operation and maintenance cost: the labor cost decreased by 80%, and the film life was extended to 5 years.
