Technical Field
[0001] This invention relates to the field of citrus cultivation technology, specifically to a citrus cultivation greenhouse for facility cultivation. Background Technology
[0002] In recent years, the citrus industry has carried out large-scale expansion of planting across the country, generating huge economic benefits. However, climate change, especially severe weather such as rainstorms, scorching sun, and cold waves, often brings huge losses to growers, or even complete crop failure. In order to create a suitable microclimate for growth, traditional citrus facility cultivation, which is analogous to the rain-sheltered facility cultivation technology for grapes, has emerged. However, traditional citrus facility cultivation mainly refers to rain-sheltered greenhouses.
[0003] Chinese invention patent application CN117178780A proposes "a citrus cultivation greenhouse for facility cultivation." This device can quickly assemble and construct the greenhouse, reducing the construction cycle and improving the construction efficiency. Furthermore, when the greenhouse needs to be dismantled after construction, it can be quickly disassembled, making the disassembled greenhouse components easier to transport. However, existing greenhouses mostly focus on optimizing the physical structure and generally lack real-time, accurate monitoring and intelligent control of the greenhouse environment. Growers often rely on experience or simple observation to determine whether ventilation, spraying, or heat preservation is needed, resulting in lagging management and difficulty in accurately meeting the precise requirements of citrus at different growth stages for temperature, humidity, carbon dioxide concentration, and soil moisture, thus affecting the quality and yield of citrus. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a citrus cultivation greenhouse for facility cultivation according to an embodiment of the present invention. A citrus cultivation greenhouse for facility cultivation includes a frame 1, which is spliced together from several support rods 11.
[0035] Ventilation mechanism 2 includes a first ventilation end 21, a second ventilation end 22, and a shielding end 23; the two ends of the canopy 1 are respectively equipped with the first ventilation end 21 for ventilation of the inside of the canopy 1, the second ventilation end 22 is provided inside the canopy 1 for accelerating the air flow inside the canopy 1, and the shielding end 23 is movably provided inside the first ventilation end 21 for shielding the air inlet 2121 and sealing the first ventilation end 21;
[0036] The sprinkler system 3 is installed inside the shed frame 1 and is used to spray water inside the shed.
[0037] The monitoring unit 4 is used to detect environmental data inside the shed 1 and to transmit it to the control panel 5 on the shed 1. The control panel 5 is also equipped with a display 51 and a central processing unit 52. The display 51 is used to display the monitoring data, and the central processing unit 52 is used to control the operation of the components.
[0038] In this embodiment, the device combines the first ventilation end 21, the second ventilation end 22, the shielding end 23, the monitoring mechanism 4, and the central processing unit 52 in the ventilation mechanism 2. This changes the traditional greenhouse management model that relies on manual experience and judgment. The monitoring mechanism 4 collects key environmental parameters such as temperature, humidity, carbon dioxide concentration, and soil moisture in real time and transmits them to the control panel 5. Growers can make scientific decisions about whether ventilation or sealing is necessary based on the real-time data on the display 51, avoiding problems such as high temperature and humidity leading to diseases or low temperature and dryness affecting growth due to misjudgment. The first ventilation end 21 is located at both ends of the greenhouse frame 1, enabling convection ventilation, effectively expelling hot and humid air and introducing fresh air to prevent stuffiness inside the greenhouse. The second ventilation end 22... Ventilation end 22 is located inside the shed 1, which can accelerate the air flow inside the shed, break the air stratification, make the temperature and humidity distribution more uniform, avoid local overheating or overhumidification, and provide a more stable and suitable growth environment for citrus. This invention can make fine-grained control according to the different environmental needs of citrus at different growth stages, such as flowering period, young fruit period and swelling period, effectively reduce physiological diseases such as fruit drop, fruit cracking and sunburn, and significantly improve fruit quality and yield per unit area. As an important part of this invention, the operation of the spraying mechanism 3 can be controlled by the central processor 52, realizing intelligent irrigation. Combined with soil moisture monitoring data, it can determine whether water needs to be added, avoiding water waste and root hypoxia caused by over-irrigation, or growth affected by insufficient irrigation.
[0039] In one embodiment, please refer to Figure 1 - Figure 5To improve the working efficiency of the ventilation mechanism 2, the first ventilation end 21 includes a partition 211 and a housing 212. The partition 211 is installed at both ends of the frame 1, and the housing 212 is installed on the partition 211. Air inlets 2121 are provided on the housing 212 and the partition 211. A mesh plate 213 is installed on the surface of the housing 212, and a shielding end 23 for shielding the air inlets 2121 is installed inside the housing 212. The second ventilation end 22 includes a duct 221 and a guide fan 222. The duct 221 is installed inside the frame 1, and a guide fan 222 is provided inside the duct 221. The shielding plate includes a wind deflector 231, a connecting push rod 232, and an electric telescopic rod 233. The wind deflector 231 is slidably connected inside the housing 212, and a side opening for the wind deflector 231 to move outward is provided on one side of the housing 212. The baffle plate 231 has multiple air guide holes 2311 that cooperate with the air inlet 2121. A connecting push rod 232 is fixed at the upper end of the baffle plate 231. The upper end of the connecting push rod 232 passes through the strip hole at the upper end of the box body 212. An electric telescopic rod 233 is installed at the upper end of the box body 212. The telescopic end of the electric telescopic rod 233 is connected to the connecting push rod 232 and is used to push the connecting push rod 232 to move in the strip hole. It can be in a first position or a second position. When the connecting push rod 232 is in the first position, the baffle plate 231 is used to block the air inlet 2121, and the air guide holes 2311 and the air inlet 2121 are misaligned. When the connecting push rod 232 is in the second position, the air guide holes 2311 on the baffle plate 231 are connected to the air inlet 2121.
[0040] In this embodiment, boxes 212 with air inlets 2121 are provided at both ends of the frame 1, and connected to the interior space of the greenhouse by partitions 211, forming an air collection and guiding channel. Compared with directly opening holes in the greenhouse film, this can more effectively guide external air in and reduce turbulence, making convection ventilation smoother and more efficient. Air ducts 221 are installed inside the frame 1, and guide fans 222 are installed within them. The air ducts 221 constrain the airflow direction, avoiding the problem of severe air diffusion caused by ordinary fans, ensuring concentrated airflow, and effectively accelerating airflow in specific areas. Multiple air ducts 221 can be arranged along the length of the greenhouse to form multi-point air supply, effectively breaking down air stratification inside the greenhouse. Hot air gathers at the top, and cold air settles at the bottom, thus improving temperature, humidity, and oxygen levels. The carbon dioxide concentration is more evenly distributed vertically and horizontally, eliminating dead zones and creating a more consistent microenvironment for citrus growth. The first ventilation end 21 is responsible for the exchange of new and old air, while the second ventilation end 22 is responsible for the mixing and circulation of air within the greenhouse. Working together, they improve the overall air renewal rate and environmental uniformity of the greenhouse, resulting in ventilation efficiency far exceeding that of a single ventilation method. The use of a sliding wind deflector 231 driven by an electric telescopic rod 233 completely eliminates manual operation, achieving automated ventilation control. When the central processor 52 issues a command based on monitoring data, such as when the temperature exceeds the limit, the electric telescopic rod 233 can immediately activate, pushing the connecting push rod 232 and causing the wind deflector 231 to switch from blocking to open within seconds, or vice versa. This is much more efficient than manual operation. The manual window opening and closing mechanism is much faster, allowing for timely responses to sudden weather changes, such as a sudden afternoon heatwave. By programming the travel of the electric telescopic rod 233, the position of the wind deflector 231 can be precisely controlled, achieving various states such as fully open, partially open, or fully closed to meet different ventilation needs. The high precision of the control is evident when the wind deflector 231 moves to its first position, completely covering the air inlet 2121 and tightly fitting with the housing 212, effectively blocking the inflow of external air and achieving a reliable physical seal. This is crucial for scenarios requiring heat preservation, humidity control, or fumigation, ensuring the effective implementation of agronomic measures. A mesh panel 213 installed on the surface of the housing 212 prevents flying insects, birds, fallen leaves, etc., from entering the ventilation channel and clogging the air inlet 2121. Or damage the internal mechanism, protect the shield end 23 inside the housing 212, which adopts a sliding connection instead of rotation or flipping, the movement trajectory is stable and the friction is relatively small. The connecting push rod 232 passes through the strip hole, providing precise guidance for the linear movement of the wind deflector 231, ensuring that it will not get stuck or deviate in the reciprocating motion. Since it is a linear sliding and only needs to overcome wind pressure and a small amount of friction, the required driving force is small. Therefore, the power of the electric telescopic rod 233 can be selected to be low, which helps to reduce the overall energy consumption of the system while ensuring the function. Although the basic function is to open / close, by controlling the extension and retraction of the electric telescopic rod 233, the continuous position adjustment of the wind deflector 231 can be achieved, thereby controlling the air intake area and realizing stepless adjustment of the air volume.
[0041] In one embodiment, please refer to Figure 1 - Figure 3 To improve the spraying efficiency, the spraying mechanism 3 includes a water tank 31, a water supply pipe 32, several spray heads 33 and a pump body 34. The water tank 31 is located outside the shed 1, and one end of the pump body 34 is connected to the inside of the water tank 31, and the other end is connected to the water supply pipe 32. The water supply pipe 32 is arranged in an arc shape inside the shed 1, and multiple spray heads 33 are provided on the water supply pipe 32. The outer wall of the water tank 31 is provided with an inlet and an outlet, and both the inlet and outlet are equipped with regulating valves.
[0042] In this embodiment, the water supply conduit 32 is designed in an arc shape within the greenhouse frame 1 and works in conjunction with multiple sprinkler heads 33 to form a scientific spray coverage pattern. The arc-shaped conduit matches the arched structure of the greenhouse, allowing it to extend longitudinally and laterally, ensuring that the spray coverage extends across the entire planting area. This avoids spray dead zones or overlapping areas caused by straight pipes. The multiple sprinkler heads 33 are evenly distributed along the arc-shaped conduit, and combined with the stable water pressure provided by the pump body 34, they can achieve uniform spraying of water mist or droplets, effectively preventing localized over-wetting or over-drying, resulting in a more uniform distribution of soil moisture. This meets the balanced water absorption needs of citrus roots, and the spraying method is closer to natural rainfall, helping to clean dust and insect eggs from the leaves and increase air humidity. It is particularly suitable for... The high humidity required during the flowering and young fruit stages of citrus trees is beneficial for improving fruit set. The combination of an external water tank 31 and a pump body 34 enables powered water supply, eliminating reliance on natural water pressure. The pump body 34, as the power source, provides continuous and stable pressure, ensuring all sprinkler heads 33 receive sufficient water and appropriate spray intensity during operation, guaranteeing consistent irrigation results. Powered water supply also allows for faster irrigation, enabling large-area spraying in a short time, making it particularly suitable for emergency scenarios requiring rapid cooling or humidification. This device does not rely on elevated water towers or municipal pipe networks; it can operate as long as there is a water source, supplemented through the inlet and powered by electricity. It is more adaptable to different installation locations. The water tank 31 is located outside the shed 1, enabling powered water supply. The separation of the water storage unit from the working unit, with the water tank 31 located outside the greenhouse, eliminates the impact of the high temperature and humidity environment inside. This facilitates routine checks of water levels, cleaning of the water tank 31, adding water-soluble fertilizers or pesticides, and maintenance of the pump 34, all without requiring entry into the greenhouse. This significantly improves the convenience and safety of maintenance. Placing the large water tank 31, which is prone to algae growth or requires regular cleaning, outside the greenhouse avoids it occupying valuable planting space and prevents the water tank 31 from overheating inside the greenhouse, thus protecting water quality and equipment. Moving the main water storage equipment outside the greenhouse simplifies the greenhouse structure, reduces obstruction of light and ventilation, and creates a more open environment for crop growth. The water tank 31 is equipped with an inlet and an outlet, and is also equipped with... The regulating valve enables controllable replenishment and discharge of water resources. Through the inlet and its regulating valve, external water sources, such as tap water, irrigation canals, or rainwater harvesting systems, can be easily connected to replenish the water tank 31. The operation is simple. After long-term use, the bottom of the water tank 31 will accumulate silt, impurities, or scale. Through the drain outlet and its regulating valve, the sewage or sediment at the bottom can be discharged regularly to keep the inside of the water tank 31 clean, prevent the sprinkler heads 33 from clogging, and ensure the long-term stable operation of the system. At the same time, it is easy to combine the water tank 31 with a rainwater harvesting device to realize the recycling of rainwater. Regular sewage discharge can prevent ineffective irrigation or disease spread caused by water quality deterioration, save water resources from the source, reduce production costs, and conform to the development direction of green agriculture.
[0043] In one embodiment, please refer to Figure 1 - Figure 8 To improve the monitoring effect of the internal environmental data of the greenhouse, the monitoring mechanism 4 includes an internal temperature and humidity sensor 41, an external temperature and humidity sensor 42, an internal carbon dioxide sensor 43, and a soil moisture sensor 44. The internal temperature and humidity sensor 41 and the internal carbon dioxide sensor 43 are installed inside the greenhouse frame 1, the external temperature and humidity sensor 42 is installed outside the greenhouse frame 1, and the soil moisture sensor 44 is installed inside the greenhouse frame 1 and is used to detect soil moisture. The monitoring mechanism 4 also includes multiple cameras 45, which are all installed inside the greenhouse frame 1. The internal temperature and humidity sensor 41, the external temperature and humidity sensor 42, the internal carbon dioxide sensor 43, the soil moisture sensor 44, and the cameras 45 are all electrically connected to the central processing unit 52. The control panel 5 is also equipped with a wireless transmission module 53 and a Bluetooth module 54, which are bidirectionally electrically connected to the central processing unit 52.
[0044] In this embodiment, by integrating indoor and outdoor temperature and humidity sensors, indoor carbon dioxide sensor 43, soil moisture sensor 44, and multiple cameras 45, and connecting them all to a central processing unit 52, and simultaneously introducing a wireless transmission module 53 and a Bluetooth module 54, a multi-source fusion, three-dimensional perception, and real-time interactive intelligent monitoring system is constructed. The monitoring parameters cover the core meteorological factors, key soil factors, and external environmental references affecting citrus growth, forming a complete data closed loop. The indoor temperature and humidity sensor 41 and the indoor carbon dioxide sensor 43 monitor the crop growth microclimate in real time, providing direct evidence for determining whether ventilation, heating, or supplemental gas or CO2 fertilization is needed. The soil moisture sensor 44 directly... The system directly monitors the rhizosphere environment, providing the most direct and accurate basis for the start and stop of the sprinkler system 3. This avoids the blindness of relying solely on experience or indoor air humidity to determine irrigation, achieving true on-demand irrigation. The outdoor temperature and humidity sensor 42 provides an external environmental benchmark. By comparing data inside and outside the greenhouse, ventilation requirements can be accurately calculated. For example, natural ventilation can be achieved by utilizing temperature differences. The system can also predict the potential impact of severe external weather such as cold waves and heavy rain on the indoor environment and take protective measures in advance. The central processor 52 can comprehensively analyze all sensor data. For example, in high temperature and low humidity weather, the system can determine that sprinklers need to be started simultaneously to increase humidity, lower temperature, and provide partial ventilation, achieving an optimal control strategy for multi-system coordination. This is achieved by integrating multiple cameras 45. Camera 45 can capture images in real-time or at set intervals of key growth stages and conditions of citrus trees, such as canopy shape, leaf color, flowering and fruit setting, fruit enlargement, and the occurrence of pests and diseases. This provides growers with the most intuitive management information. Through these images, staff can remotely diagnose pest and disease types and assess nutritional status, addressing problems at their earliest stages. Growers no longer need to frequently enter the greenhouse for manual inspections, reducing labor intensity and the risk of disease transmission due to personnel movement. Continuous image recording creates a complete crop growth record, which can be used for scientific research, quality traceability, or showcasing the green production process to consumers. All sensors and cameras 45 are electrically connected to the central processing unit 52, forming a data hub, and connected wirelessly... The transmission module 53, such as Wi-Fi, 4G / 5G, and Bluetooth module 54, enables bidirectional communication. Through the wireless transmission module 53, all monitoring data, including sensor readings and camera images 45, can be uploaded to the cloud or the grower's mobile phone / computer APP in real time. Users can keep track of the greenhouse situation at any time. The bidirectional electrical connection means that not only can data be uploaded, but instructions can also be issued. Growers can remotely view data, receive alarms, and directly remotely control the switching of actuators such as ventilation and sprinklers through the mobile APP, achieving integration. The Bluetooth module 54 provides a short-range, low-power local connection method, which can be used to quickly pair the control panel 5 with mobile phones and tablets for parameter settings or firmware upgrades.
[0045] To better understand this invention, the following is combined with... Figures 1 to 8The technical solution of the present invention will be described in detail below:
[0046] S1. Turn on the power of the control panel 5. The central processing unit 52 starts up and performs a system self-test to confirm that all electrical connection devices, such as the greenhouse temperature and humidity sensor 41, the greenhouse external temperature and humidity sensor 42, the greenhouse carbon dioxide sensor 43, the soil moisture sensor 44, multiple cameras 45, the electric telescopic pole 233, and the pump body 34, are communicating normally. The system enters standby mode to receive and process data.
[0047] S2. Monitoring agency 4 begins to continuously and in real-time collect multi-dimensional environmental data:
[0048] The temperature and humidity sensor 41 and the carbon dioxide sensor 43 inside the greenhouse continuously monitor the temperature, relative humidity and CO2 concentration of the air inside the greenhouse.
[0049] The soil moisture sensor 44 penetrates deep into the main root distribution layer of citrus trees to detect the soil volumetric water content in real time.
[0050] The 42 external temperature and humidity sensors simultaneously collect the temperature and humidity outside the greenhouse, providing key comparative data for ventilation decisions;
[0051] Multiple cameras 45 take high-definition images of different areas inside the greenhouse at preset time intervals, such as every hour or automatically triggered according to lighting conditions, recording the canopy shape, leaf color, flowering and fruit setting of citrus trees and signs of potential pests and diseases.
[0052] S3. All sensor data and camera images collected in S2 are transmitted to the central processor 52 in real time via wired or wireless means. The central processor 52 performs data fusion analysis, compares the temperature and humidity differences inside and outside the greenhouse, judges the potential and efficiency of natural ventilation, and assesses the photosynthetic efficiency by combining light intensity, external sensors or time calculations with CO2 concentration. It also accurately judges irrigation needs by combining air humidity and soil moisture, avoiding the blindness of watering based on weather conditions. Using image recognition algorithms, or marking for manual review, the crop growth status is preliminarily analyzed.
[0053] S4 and the central processing unit 52 automatically generate ventilation or sealing control commands based on the analysis results of S3. When the temperature inside the shed exceeds the set upper limit, such as 35°C, or the humidity is too high or the CO2 concentration is too low, the system automatically activates the first ventilation end 21 and the second ventilation end 22. Specifically, the electric telescopic rod 233 extends, pushes the connecting push rod 232, and drives the wind baffle 231 to slide to the second position inside the box 212, so that the air guide hole 2311 on the wind baffle 231 connects with the air inlet hole 2121 on the box 212 and the partition 211, allowing external air to flow in. At the same time, the guide fan 222 in the air duct 221 starts, forcing the air inside the shed to circulate, breaking the stratification, and achieving efficient and uniform ventilation. When heat preservation is required, such as low temperature at night, humidification, or chemical fumigation, the system automatically activates the shielding end 23, the electric telescopic rod 233 retracts, and drives the wind baffle 231 to move to the first position, which completely and tightly shields the air inlet hole 2121, achieving physical sealing and blocking the exchange of internal and external air.
[0054] S5. Based on the analysis results of S3, especially the soil moisture data, when the soil moisture is lower than the preset threshold, the central processor 52 automatically starts the sprinkler mechanism 3 and the pump 34 works to pressurize the water in the water tank 31 and deliver it to multiple sprinkler heads 33 evenly distributed on it through the arc-shaped water supply pipe 32. The sprinkler heads 33 spray evenly in a mist or drizzle to cover the entire planting area, effectively replenishing soil moisture, reducing greenhouse temperature or increasing air humidity. The spraying time can be dynamically adjusted according to the real-time feedback of the soil moisture sensor 44 to achieve irrigation on demand.
[0055] S6. Through the integrated communication module, remote management and convenient interaction are realized. Using the wireless transmission module 53, all monitoring data from S2 to S5, including temperature and humidity, CO2, soil moisture curves, and camera images 45, are uploaded to the cloud in real time. Growers can check the vital signs of the greenhouse and crop growth anytime and anywhere through a dedicated APP on their mobile phones or computers. Users can remotely receive system alarms, such as high temperature, low temperature, and equipment failure, through the APP, and directly manually turn ventilation and sprinkler on / off, or modify automation rules on the APP. Through the Bluetooth module 54, users can quickly pair their mobile phones with the control panel 5 to set parameters, view historical data, or upgrade firmware, making operation convenient.
[0056] S7. To ensure long-term stable operation of the system, regular maintenance is required. When the water level in the water tank 31 is too low, the water level sensor or APP can prompt the system to open the regulating valve at the inlet and connect to an external water source, irrigation canal, or rainwater collection system to replenish the water tank 31. Regularly, such as once a month, open the regulating valve at the outlet to remove the silt, impurities, and sediment accumulated at the bottom of the water tank 31 to keep the water clean and prevent the sprinkler heads 33 from clogging. Regularly check whether the screen plate 213 is blocked by debris, clean the lens of the camera 45 to ensure clear visual monitoring, and check the operating status of moving parts such as the electric telescopic rod 233 and the pump body 34.

Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
