Description

Technical Field

[0001] The invention relates to the technical field of glass greenhouses, and in particular to an intelligent greenhouse system. Background Art

[0002] Glass greenhouse refers to a greenhouse that uses glass as a lighting material. It is a type of greenhouse. Among cultivation facilities, glass greenhouses have the longest service life and are suitable for use in a variety of regions and climate conditions. The area and usage can be freely adjusted by the greenhouse owner. The smallest one is a courtyard leisure type, and the largest one is a glass building with a height of more than 10 meters and a span of more than ten meters.

[0003] Usually, a sunshade system is installed on the top of the glass greenhouse. When the intensity of sunlight is too strong, the sunshade system is often adjusted to reduce the intensity of light radiated to the leaves of the plants to ensure the normal growth of the plants. The traditional greenhouse sunshade system uses a sunshade net to shade the sun by scaling the sunshade area. This method not only requires a complex support structure on the top of the greenhouse, but also cannot achieve zero sunshade. The existing ventilation methods are mainly natural ventilation and forced ventilation. Regardless of the ventilation method, exhaust vents and air inlets need to be set on the glass greenhouse. For most greenhouses, exhaust vents and air inlets are set around the glass greenhouse. On the one hand, this arrangement will affect the appearance of the entire glass greenhouse, destroy the integrity of the glass curtain wall, and the aesthetics are not high. On the other hand, the speed and effect of ventilation are not good, and energy loss is high. In addition, the existing glass greenhouse cannot collect heat in the hot air very well, and most of the hot air is discharged and wasted; when the sun sets at night, a large amount of electric energy is required to heat to maintain the temperature, resulting in excessively high use costs. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent greenhouse system in view of the problems existing in the prior art.

[0005] To achieve the above object, the technical solution adopted by the present invention is: An intelligent greenhouse system comprises a glass greenhouse, wherein the glass greenhouse is provided with at least a ventilation system, a heat exchange energy storage system, a heat preservation system and a sunshade system arranged on the top of the glass greenhouse; The ventilation system comprises an exhaust passage arranged on the top and / or upper side wall of the glass greenhouse, a top window is arranged in the exhaust passage, and a fan is also arranged at the exhaust passage; a plurality of ducts are arranged below the side wall of the glass greenhouse, a wet curtain is arranged in the duct, and an air inlet arranged opposite to the wet curtain, and a side window is arranged at the air inlet; The heat exchange energy storage system comprises an underground water tank arranged below the glass greenhouse, wherein a heat exchange pipeline assembly is arranged in the underground water tank; a plurality of heat exchange air inlets are arranged above the glass greenhouse, and a plurality of heat exchange air outlets are arranged below the glass greenhouse, wherein the heat exchange air inlets and the heat exchange air outlets are respectively connected to the heat exchange pipeline assembly; or a heat exchanger system with water as the medium connected to the heat exchange pipeline assembly is arranged in the greenhouse; and the heat source used for heat exchange is the hot air at the top of the greenhouse; The thermal insulation system comprises a wall with a thermal conductivity of less than 1 W / (m·K), wherein the wall is a multi-layer hollow glass wall or a vacuum glass wall or a thermal insulation wall; The sunshade system includes a sunshade assembly arranged above the roof of the glass greenhouse, and the sunshade assembly automatically adjusts the light flux in the glass greenhouse according to the lighting requirements of the plants.

[0006] The overall system ensures that the greenhouse operates stably between 15-35 degrees Celsius all year round, relying only on solar energy, without relying on external energy input, through efficient light energy incident, high heat energy conversion and storage, effective heat energy release, high-efficiency insulation measures and intelligent control systems.

[0007] This intelligent greenhouse system provides a glass greenhouse that can automatically control temperature and light intensity, and can store the high temperature generated in the glass greenhouse in the form of energy storage. It can not only reasonably adjust the temperature in the greenhouse, but also obtain heat energy, making the entire greenhouse more environmentally friendly and low-energy consumption, saving energy, and forming a self-circulating independent ecosystem.

[0008] The heat exchange energy storage system, through the arrangement of the underground water tank and the heat exchange pipeline assembly, can convert the heat of the high-temperature air in the glass greenhouse into water temperature and store it in the underground water tank, while releasing low-temperature air to keep the temperature in the glass greenhouse within the comfortable temperature range required for plant growth. In the process of this air circulation, the air thermal energy can be preserved in another way. In low-temperature environments such as at night, the air circulation can be used to exchange the heat in the water to increase the greenhouse temperature at night, allowing it to maintain the greenhouse temperature at night without consuming electrical energy.

[0009] The ventilation system can more effectively control the temperature and air circulation in the entire glass greenhouse, and cooperate with the heat exchange energy storage system to help keep the temperature in the glass greenhouse within the temperature range required by the plants. The air inlet is set at the duct where the wet curtain is arranged. On the one hand, when the air enters, the higher temperature wind can be cooled by the wet curtain before entering the glass greenhouse. On the other hand, the duct and the wet curtain are used to block the air, so that there is no obvious air inlet outside the glass greenhouse, which improves the aesthetics of the entire greenhouse and makes full use of the space at the duct.

[0010] The shading system utilizes a deflectable visor assembly to adjust the light flux in the house. While ensuring the light intensity requirements of the plants, the visor assembly can be controlled to block the sunlight to protect the plants from being damaged by excessive light. The greenhouse can also be cooled by blocking sunlight.

[0011] The ventilation system, heat exchange energy storage system and sunshade system of the glass greenhouse can be used independently or complement each other, especially in the indoor temperature control and heat energy utilization of the glass greenhouse.

[0013] Furthermore, the outside of the glass greenhouse is surrounded by earth slopes, which have certain insulation and heat storage functions. A number of ducts are arranged at intervals on the earth slopes on both sides, and the wet curtains are arranged outside the ducts. The side windows open in the direction of the wet curtains.

[0014] Furthermore, the exhaust ducts are arranged at intervals along the length direction of the roof of the glass greenhouse and are arranged in multiple rows; the exhaust ducts are arranged at the highest position of the roof, and a drainage groove is provided at the lowest point where the room roof contacts the exhaust ducts.

[0015] Furthermore, the fans are arranged in one-to-one correspondence with the exhaust passages and keep a distance from the entrance of the exhaust passages; the fans are installed under the roof of the glass greenhouse through a hanger, or the fans are installed on the inner wall of the glass greenhouse through a bracket.

[0016] Furthermore, the heat exchange pipeline assembly includes a heat exchange pipeline arranged in the underground water tank, and an air inlet pipeline and an air outlet pipeline connected to the heat exchange pipeline, the air inlet pipeline extends upward along the glass greenhouse and is provided with the heat exchange air inlet, and the air outlet pipeline is distributed at a lower position of the glass greenhouse and is provided with the heat exchange air outlet. Another heat exchange method is to pump water to the fan coil for heat exchange.

[0017] Furthermore, the underground water tank is a concealed ditch arranged under the glass greenhouse, the concealed ditch is arranged in a circuitous manner, a number of inspection passages are arranged at intervals on the concealed ditch, the inspection passages extend out of the ground of the glass greenhouse and are provided with inspection ports with covers; a ground channel is also provided on the concealed ditch, the ground channel extends to the ground of the glass greenhouse and is provided with a grille cover.

[0018] Furthermore, the roof of the glass greenhouse is a continuous undulating structure, and the sunshade assembly includes a sunshade, and a traction rope or traction rod connected to the sunshade; one end of the sunshade is rotatably installed at the bottom of the roof, and the other end of the sunshade is connected to the traction rope or traction rod, and a plurality of fixed pulleys are respectively provided at the peak and the bottom of the roof. The traction rope passes around the fixed pulley at the peak and is connected to the adjacent sunshade. After stringing together each row of the sunshades in turn, the traction rope then passes around the fixed pulley at the peak and the fixed pulley at the bottom of the valley and returns to the winch assembly, and the winch assembly is installed at the peak of the roof through a support.

[0019] If it is a traction rod, it is a rigid connection that can make multiple rows of sunshades rigidly connected in series and move synchronously. The transmission shaft is directly rotated and deflected, or the rotation shaft is pulled and pushed by a traction rope or a traction rod to deflect.

[0020] Furthermore, the hoisting assembly includes a hoisting shaft and a servo motor connected to and driving the hoisting shaft; a plurality of connection holes or connection rings for connecting the traction rope are provided above the sun visor; the sun visor is a solar panel; and a light intensity sensor is also provided on the sun visor. The hoisting assembly can also be a winch.

[0021] Furthermore, the intelligent greenhouse system also includes the following control methods: During the operation of the glass greenhouse, the heat exchange energy storage system sucks hot air in the glass greenhouse from the heat exchange air inlet, and discharges cold air from the heat exchange air outlet after heat exchange; If the temperature adjustment in the glass greenhouse exceeds the heat exchange capacity of the heat exchange energy storage system or ventilation is required, the ventilation system intervenes to work, according to the most suitable temperature range Tmin~Tmax in the glass greenhouse set for different crops, assuming that the real-time temperature in the glass greenhouse is T, and judge the relationship between T and Tmax, as well as the relationship between T and Tmin, to determine whether to open the top window and the side window, and whether to start the wet curtain and the fan; The shading system is adjusted according to the light intensity and temperature changes inside the glass greenhouse. The real-time detected light intensity inside the glass greenhouse is assumed to be S1. The most suitable light intensity range inside the glass greenhouse is set to be Smin~Smax according to different crops.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Example 1

[0026] like Figure 1 to Figure 7 As shown, an intelligent greenhouse system includes a glass greenhouse 1, wherein the glass greenhouse 1 is provided with at least a ventilation system, a heat exchange energy storage system, a heat preservation system and a sunshade system arranged on the top of the glass greenhouse; The ventilation system includes an exhaust duct 6 arranged on the top and / or upper side wall of the glass greenhouse 1, a top window 7 is arranged in the exhaust duct 6, and a fan is also arranged at the exhaust duct 6; a plurality of ducts 8 are arranged below the side wall of the glass greenhouse 1, a wet curtain 9 is arranged in the duct 8, and an air inlet 10 arranged opposite to the wet curtain 9, and a side window 11 is arranged at the air inlet 10; The heat exchange energy storage system comprises an underground water tank 12 arranged below the glass greenhouse 1, a heat exchange pipeline assembly is arranged in the underground water tank 12, a plurality of heat exchange air inlets are arranged above the glass greenhouse 1, and a plurality of heat exchange air outlets are arranged below the glass greenhouse 1, and the heat exchange air inlets and the heat exchange air outlets are respectively connected to the heat exchange pipeline assembly; The shading system includes a visor assembly arranged above the roof of the glass greenhouse 1. The visor assembly automatically adjusts the light flux in the glass greenhouse according to the lighting requirements of the plants. The adjustable visor can also be a photovoltaic panel, so that the surplus light energy can be used to generate electricity without affecting the growth of greenhouse crops, thereby maximizing the use of solar energy.

[0027] This intelligent greenhouse system provides a glass greenhouse that can automatically control temperature and light intensity, and can store the high temperature generated in the glass greenhouse in the form of energy storage. It can not only reasonably adjust the temperature in the greenhouse, but also obtain heat energy, making the entire greenhouse more environmentally friendly and low-energy consumption, saving energy, and forming a self-circulating independent ecosystem.

[0028] The heat exchange energy storage system, through the arrangement of the underground water tank 12 and the heat exchange piping assembly, can convert the heat of the high-temperature air in the glass greenhouse into water temperature and store it in the underground water tank 12, while releasing low-temperature air to keep the temperature in the glass greenhouse within the comfortable temperature range required for plant growth. In the process of air circulation, the air thermal energy can be preserved in another way. In low-temperature environments such as at night, the air circulation can be used to exchange the heat in the water to increase the greenhouse temperature at night, allowing it to maintain the greenhouse temperature at night without consuming electrical energy.

[0029] This heat exchange energy storage system can function in different seasons, whether in winter or in hot summer. Through heat storage, insulation and heat exchange, the water temperature in the underground water tank can be adjusted to around 25-30 degrees Celsius, which can also be used as the optimal water temperature for warm water aquaculture. On winter nights, there is no greenhouse effect and the air in the greenhouse will cool down quickly. At this time, the heat energy in the hot water will be circulated and released into the air to heat the greenhouse air and keep the temperature of the greenhouse under control at no less than 15 degrees Celsius.

[0030] The ventilation system can more effectively control the temperature and air circulation in the entire glass greenhouse. When combined with the heat exchange energy storage system, it is more conducive to maintaining the temperature in the glass greenhouse within the temperature range required by the plants. The exhaust duct 6 on the top of the room is arranged vertically, and the top window 7 arranged therein plays the role of exhaust ventilation and also plays the role of shielding rainwater during the opening and closing process, preventing rainwater from flowing into the room from the exhaust duct. The fan is arranged below the exhaust duct and at a certain distance from the exhaust duct. Through such an arrangement, a Bernoulli effect can be formed here, thereby amplifying the air volume of the fan, which is conducive to rapid exhaust ventilation.

[0031] The air inlet 10 is arranged at the duct 8 where the wet curtain 9 is arranged. On the one hand, when the air is taken in, the wind with a higher temperature can be cooled by the wet curtain before entering the glass greenhouse. On the other hand, the duct and the wet curtain are used to shield the air so that there is no obvious air inlet outside the glass greenhouse, which improves the aesthetics of the entire greenhouse and makes full use of the space at the duct.

[0032] The shading system uses a deflectable visor assembly to adjust the light flux in the house. Under the condition of ensuring the light intensity requirement of the plants, the visor assembly can be controlled to block the sunlight to protect the plants from being damaged by excessive light. At the same time, the greenhouse can be cooled by blocking the sunlight. Shading can be achieved by deflecting the angle of the visor assembly and the sunlight, which can achieve zero shading or full shading. Compared with the traditional shading net system, it has more shading advantages and adjustability; if a photovoltaic panel is used as a shading assembly, power output can be achieved while shading.

[0033] The ventilation system, heat exchange energy storage system, thermal insulation system and sunshade system of the glass greenhouse can be used independently or complement each other, especially in the indoor temperature control and heat energy utilization of the glass greenhouse.

[0034] The exhaust passage and the air inlet work in coordination with each other, and the heat exchange air inlet and the heat exchange air outlet also work in coordination with each other. Low-temperature air flows in from the bottom of the glass greenhouse, and high-temperature air is discharged from the top of the glass greenhouse, which conforms to the principle of air flow. Hot air rises and cold air sinks. Such an arrangement is conducive to ventilation and temperature regulation. The top-opening window and the side-opening window are both electric glass windows, which can be independently controlled and opened and closed as needed.

[0035] Furthermore, the glass greenhouse 1 includes a keel system 5, and a glass curtain wall and a glass roof installed on the keel system 5, the glass curtain wall and the glass roof are respectively made of tempered vacuum glass, and the front and rear sides of the glass greenhouse 1 are respectively provided with sliding doors 3, the sliding doors 3 are provided with a canopy outside, and the indoor side of the sliding doors 3 is provided with an independent buffer room 4.

[0036] The entire glass greenhouse 1 has a beautiful appearance, especially when all the exhaust ducts 6 are arranged on the top of the glass greenhouse 1. There are no obviously visible exhaust ducts and windows around the glass greenhouse 1. The glass greenhouse 1 is directly built with full-size curtain wall glass around, which is beautiful and atmospheric.

[0037] The glass curtain wall and glass roof are both made of tempered vacuum glass, which has high strength and thin thickness, as well as strong heat insulation. The vacuum structure and low-e coating technology can effectively prevent indoor temperature transfer and reduce heat loss in the greenhouse, especially in winter. The keel system is set on the indoor side. When viewed from the outside, the glass curtain wall has no exposed metal parts and no heat conductor running through the wall, which further avoids heat transfer from the metal.

[0038] The glass greenhouse 1 is provided with sliding doors 3 at the front and rear. In order to reduce the heat exchange between the indoor and outdoor at the sliding doors and the impact of people entering and leaving the greenhouse on the internal environment, an independent buffer room 4 is provided on the indoor side. The buffer room 4 is also a glass structure. In this embodiment, the glass greenhouse has a construction area of ​​more than 2,000 square meters, a length of more than 50 meters, a width of more than 40 meters, and a height of about 7 meters.

[0039] Furthermore, the outside of the glass greenhouse 1 is surrounded by earth slopes 2, and a plurality of ducts 8 are provided at intervals on the earth slopes 2 on both sides. The wet curtains 9 are arranged outside the ducts 8, and the side windows 11 open in the direction of the wet curtains 9.

[0040] The soil slope protection 2 can not only improve the foundation stability of the entire glass greenhouse, but also plant green plants to improve the external aesthetics of the entire glass greenhouse; the duct 8 is a concrete structure, which can be used as part of the supporting foundation of the keel frame system. Setting it there can not only keep its low-position arrangement, which is conducive to the wet curtain to play a better role, but also avoid setting the wet curtain system on the glass curtain wall. The duct 8 has a large space inside, which can not only accommodate the wet curtain 9, but also allow the side window 11 to open in an outward-opening form. The reason why it does not open inward is that the keel frame system of the glass curtain wall is set on the indoor side to avoid movement interference caused by opening inward. Secondly, opening inward will occupy the space of the greenhouse.

[0041] Furthermore, the exhaust ducts 6 are arranged at intervals along the length direction of the roof of the glass greenhouse 1, and are arranged in multiple rows; the exhaust ducts 6 in each row can be arranged at adjacent intervals of 600-700mm, 1100-1200mm, 2200-2300mm, etc. according to the location and the needs of the roof structure. The exhaust duct is arranged at the highest position of the roof, and a drainage groove is provided at the lowest point where the roof contacts the exhaust duct.

[0042] The roof 101 of the glass greenhouse 1 is designed to be an undulating wave-shaped structure, which is designed for the sake of aesthetics and for the purpose of adjusting the indoor sunlight with the sunshade system. Under this structure, the exhaust duct is preferably arranged at the crest of the wave, and the bottom surface of the exhaust duct is an inclined surface installed on the glass on the top of the room. The top window is located at the inclined surface and can be flipped upward to open. A drainage groove is provided at the lowest point where the bottom of the exhaust duct meets the roof, which can drain rainwater in the exhaust duct to avoid water accumulation and prevent rainwater from leaking into the room.

[0043] Furthermore, the fan is arranged in one-to-one correspondence with the exhaust duct 6 and maintains a distance from the entrance of the exhaust duct 6; the fan is installed under the roof of the glass greenhouse through a hanger, or the fan is installed on the inner wall of the glass greenhouse through a bracket.

[0044] The fan is arranged below the exhaust passage 6 and at a certain distance from the exhaust passage. Such an arrangement can form a Bernoulli effect here, thereby amplifying the air volume of the fan, which is conducive to rapid exhaust ventilation.

[0045] Furthermore, the heat exchange pipeline assembly includes a heat exchange pipeline 15 arranged in the underground water tank 12, and an air inlet pipeline and an air outlet pipeline connected to the heat exchange pipeline 15, the air inlet pipeline extends upward along the glass greenhouse 1 and is provided with the heat exchange air inlet, and the air outlet pipeline is distributed at a low position of the glass greenhouse and is provided with the heat exchange air outlet.

[0046] The air intake pipeline extends upward along the keel system and is connected and fixed by means of pipe clamps, brackets and other components, so that the heat exchange air inlet is located above the greenhouse, which is conducive to absorbing the rising hot air flow; an induced draft fan can be set at one end of the pipeline to guide the air flow to flow in an orderly manner.

[0047] A large amount of water is arranged in the underground water tank 12. The heat exchange pipe 15 is arranged in the underground water tank 12 through a bracket. When hot air passes through the heat exchange pipe, it will exchange heat with the external water, thereby taking away the heat in the air and discharging cold air. A plurality of inclined partitions 16 are arranged in the heat exchange pipe 15 along the air flow direction. The partitions 16 and the heat exchange pipe 15 are made of metal materials with excellent heat transfer performance. These partitions 16 can increase the contact area between air and metal, thereby increasing the heat exchange efficiency with water, and greatly improving the heat exchange efficiency and effect without affecting the air flow speed and smoothness.

[0048] Furthermore, the underground water tank 12 is a culvert arranged under the glass greenhouse 1, the culvert is arranged in a circuitous manner, and a plurality of inspection passages 13 are arranged at intervals on the culvert, the inspection passages 13 extend out of the ground of the glass greenhouse 1 and are provided with inspection ports with covers; a ground channel 14 is also provided on the culvert, the ground channel 14 extends to the ground of the glass greenhouse 1 and is provided with a grille cover.

[0049] These underground ditches can be set up when the glass greenhouse is built. They are all concrete structures with waterproof and heat-insulating measures. The setting of the inspection channel 13 is convenient for repairing the pipes therein. The underground channel 14 has a built-in circulation pump to keep the water flowing in the ditch. A filter is set in the underground channel to keep the water clean.

[0050] Further, combined with Fig.10 As shown, the roof 101 of the glass greenhouse 1 is a continuously undulating structure, and the sunshade assembly includes a sunshade 17 and a traction rope 18 connected to the sunshade 17; one end of the sunshade 17 is rotatably mounted at the bottom of the roof 101, and the other end of the sunshade 17 is connected to the traction rope 18. A plurality of fixed pulleys 22 are respectively arranged at the top and bottom of the roof, and the traction rope 18 is connected to the adjacent sunshade 17 after passing the fixed pulley 22 at the top. After the sunshades 17 of each row are strung together in sequence, the traction rope is then passed around the fixed pulley at the top and the fixed pulley at the bottom of the valley and returned to the winch assembly 21. The winch assembly 21 and the fixed pulley at the top are respectively mounted at the top of the roof 101 through the second support 20. The fixed pulley at the bottom of the valley is fixedly mounted through a small pulley frame.

[0051] By setting the traction rope 18 and the plurality of fixed pulleys 22 arranged at high and low positions, each row of sun visors 17 can be connected in series, and the angles can be deflected and adjusted synchronously when the hoisting assembly 21 is retracted and lowered. There is no need to set many hoisting assemblies 21, and hoisting assemblies can be set only on both sides, or only on one side.

[0052] In some embodiments, Figure 8 As shown, a first support 19 is provided at the valley bottom of the roof 101, and the lower part of the sun visor 17 is connected to the first support 19 through a rotating shaft. If a fixed pulley is provided below, it can be staggered or set in the empty space for rotation connection below the sun visor; a second support 20 is provided at the peak of the roof 101, and a winch assembly 21 is provided on the second support 20. The upper part of the sun visor 17 is connected to the winch assembly 21 on the peak on one side through a traction rope 18, and the upper part of the sun visor 17 is connected to the winch assembly 21 on the peak on the other side through the traction rope 18 or is connected to a counterweight block or a fixed pulley.

[0053] For the sun visor 17, it needs to reciprocate within a certain range. The traction rope arranged on only one side of the sun visor cannot meet the adjustment requirements. Therefore, a traction rope is also arranged on the other side of the sun visor. Figure 6 As shown, the sunshade 17 is subjected to traction forces (such as F1 and F2) at adjacent wave crests, and the sunshade is deflected by changing the forces of F1 and F2. F1 and F2 can be connected to motors respectively to achieve sunshade deflection by retracting and releasing the traction rope, or one of them can be connected to a counterweight block with a fixed weight, and the other can be controlled by the motor to retract and release, or each row of sunshades can be connected in series using a wire rope and a fixed pulley and then returned to the winch assembly.

[0054] When the sun visor 17 is parallel to the sunlight, the sun visor 17 has a minimum shading rate and can achieve no shading; the maximum shading rate is related to the solar incident angle. When the angle between the sunlight and the ground is less than 30 degrees, basically 100% shading can be achieved. When the angle between the sunlight and the ground is 90 degrees, the maximum shading coefficient is about 50%.

[0055] Further, such as Fig. 9 As shown, the hoisting assembly 21 includes a hoisting shaft 2101, and a servo motor 2102 connected to and driving the hoisting shaft 2101, and the hoisting shaft 2101 is installed on the second support 20 through a bearing seat 2103; a plurality of connecting holes or connecting rings for connecting the traction rope are provided above the sun visor 17; the servo motor 2102 drives the hoisting shaft 2101 to rotate forward and reverse, hoist or release the traction rope 18, so that the sun visor 17 is deflected, and the sun visor 17 can hover at any angle.

[0056] The sun visor 17 is a solar panel, and a light intensity sensor is also provided on the sun visor 17 .

[0057] When the sunshade 17 is a solar panel, it can achieve power output without affecting plant growth. At this time, the primary purpose of the sunshade is still to shade and adjust the light intensity in the room, but in the process of shading, it can timely absorb light energy and convert it into electrical energy. For a large glass greenhouse, the electricity generated by the setting of these solar sunshades is fully capable of supplying electricity to the entire glass greenhouse. It should be noted that when adjusting the angle of the sunshade 17, the primary purpose is not to absorb sunlight to generate electricity.

[0058] The light intensity sensor can obtain the light intensity value in real time, and its purpose is to control the direction and angle of the sun visor deflection according to the light intensity value. For example, two support plates with an angle are set above the sun visor, which can be staggered; a light intensity sensor is set on the front and back sides of the two support plates respectively, and the sum of the light intensity values ​​on the front and back sides of the two support plates is compared, and the direction of the sun visor deflection is determined according to the sum of the light intensity values.

[0059] Furthermore, the intelligent greenhouse system also includes the following control methods: During the operation of the glass greenhouse, the heat exchange energy storage system sucks hot air in the glass greenhouse from the heat exchange air inlet, and discharges cold air from the heat exchange air outlet after heat exchange; If the temperature adjustment in the glass greenhouse exceeds the heat exchange capacity of the heat exchange energy storage system or ventilation is required, the ventilation system intervenes and works according to the most suitable temperature range Tmin~Tmax in the glass greenhouse set for different crops. The real-time temperature in the glass greenhouse is set as T, and the relationship between T and Tmax, as well as the relationship between T and Tmin, is judged to determine whether to open the top window and the side window, and whether to start the wet curtain and the fan.

[0060] Specifically, it is determined whether T is greater than Tmax, if so, it is determined whether the top opening window and the side opening window are opened, if they are opened, the wet curtain and the fan are turned on, if not, the top opening window and the side opening window are turned on; Determine whether T is greater than Tmax, if not, then continue to determine whether T is greater than Tmin, if yes, then determine whether the wet curtain and the fan are turned on, if yes, then turn off the wet curtain and the fan; If it is determined that T is less than Tmin, then it is determined whether the wet curtain and the fan are turned on. If they are turned on, the wet curtain and the fan are turned off, and the top window and the side window are closed.

[0061] By linking the ventilation function with the temperature control of the glass greenhouse, the energy consumption required for temperature regulation of the glass greenhouse can be minimized. By using a reasonable air intake and exhaust system, the temperature in the greenhouse can also be accurately controlled. Especially in summer, the system can timely control the opening of the ventilation equipment, adjust the ambient temperature in the glass greenhouse, maintain environmental comfort, and meet the needs of normal crop growth.

[0062] The shading system is adjusted according to the light intensity and temperature changes inside the glass greenhouse. The real-time detected light intensity inside the glass greenhouse is assumed to be S1. The most suitable light intensity range inside the glass greenhouse is set to be Smin~Smax according to different crops. The size of S1 and Smax, as well as the size of S1 and Smin, is judged to adjust the deflection direction of the visor assembly.

[0063] Specifically, support plate one and support plate two are arranged above the sun visor, and there is an angle a between support plate one and support plate two; a light intensity sensor is respectively arranged on the front and back sides of support plate one, denoted as A1 and A2; a strong light sensor is also respectively arranged on the front and back sides of support plate two, denoted as B1 and B2; the sum of the light intensity values ​​of A1+A2 is compared with the sum of the light intensity values ​​of B1+B2, and the deflection direction of the sun visor is determined according to the size of the sum of the light intensity values.

[0064] Determine whether S1 is greater than Smax. If not, jump to the next step. If so, compare the sum of the light intensity values ​​of A1+A2 with the sum of the light intensity values ​​of B1+B2. If the sum of the light intensity values ​​of A1+A2 is greater than the sum of the light intensity values ​​of B1+B2, adjust the sun visor to deflect in the direction of the support plate one; if the sum of the light intensity values ​​of A1+A2 is less than the sum of the light intensity values ​​of B1+B2, adjust the sun visor to deflect in the direction of the support plate two; Determine whether S1 is less than Smin. If not, it indicates that the sun visor is in a suitable position and no adjustment is made. If so, compare the sum of the light intensity values ​​of A1+A2 with the sum of the light intensity values ​​of B1+B2. If the sum of the light intensity values ​​of A1+A2 is greater than the sum of the light intensity values ​​of B1+B2, adjust the sun visor to deflect toward the direction of support plate two. If the sum of the light intensity values ​​of A1+A2 is less than the sum of the light intensity values ​​of B1+B2, adjust the sun visor to deflect toward the direction of support plate one.

[0065] The above method can more accurately control the direction and angle of deflection of the sun visor, and can adaptively adjust the sun visor according to the position of sunlight and indoor light intensity, with a high level of automation and intelligence. Example 2

[0066] This embodiment provides another technical solution for the synchronous swinging of the sunshade assembly. The driving mechanism includes a driving motor arranged on the roof and a traction rod connected to the sunshade, and the driving motor is connected to and drives the traction rod through a transmission assembly.

[0067] Specifically, Figures 11 to 15 As shown, a fixed bracket 24 is provided on the side of the roof, and a rotatable long screw 26 and a driving motor 25 connected to and driving the long screw 26 are connected to the side of the fixed bracket 24; a movable (threaded) slider 27 is provided on the long screw 26, and a push-pull rod 28 is connected to one side of the slider 27 through a rotating shaft; a traction rod 23 is provided above the sun visor 17 on the roof, and the traction rod 23 is rotatably connected to the sun visor 17, and a hinge seat 31 is provided on the rightmost sun visor 17 (the sun visor close to the long screw), which can be one or more, and the end of the traction rod 23 and the end of the push-pull rod 28 are connected through the hinge seat 31.

[0068] When the driving motor 25 drives the long screw 26 to rotate, the slider 27 reciprocates on the long screw 26. Since each node is hinged or rotationally connected, the push-pull rod 28 allows the sun visor 17 to swing within a certain angle during the forward and backward movement. The driving motor can be a stepping motor with an output shaft, or a through-type screw stepping motor that combines a long screw and a motor.

[0069] When the slider 27 moves to the left limit position, the push-pull rod 28 pushes the traction rod 23 and the sunshade 17, allowing the sunshade 17 to swing to the left and be parallel to the slope on one side of the roof; when the slider 27 moves to the right limit position, the push-pull rod 28 pulls the traction rod 23 and the sunshade 17, allowing the sunshade 17 to swing to the right and be parallel to the slope on the other side of the roof. Through this arrangement, the entire row of sunshades 17 can be driven to move together synchronously, so that the roof is adjusted synchronously.

[0070] Furthermore, a guide rod 29 parallel to the long screw is provided on the side of the fixed bracket 24, and bearing support seats 23 are provided at both ends of the guide rod 29 respectively, and the long screw 26 is connected to the bearing support seat 23, and the guide rod 29 itself can also be supported on the roof through a support rod; through such a setting, the supporting stability of the long screw 26 can be improved, and at the same time, a guide sleeve is provided on the guide rod 29, and the guide sleeve is connected to the slider 27, which can guide and limit the slider during the movement of the slider 27.
