Description

Technical Field

[0001] This utility model relates to the field of digital agricultural technology, specifically to an intelligent environmental control system for grape production facilities. Background Technology

[0002] In modern agricultural production, greenhouses create a relatively stable environment for the growth of fruits, vegetables, and other crops. However, greenhouses currently face many problems in practical applications. Studies show that the light intensity received by fruits and vegetables in greenhouses is only about 60% of that under natural conditions, and weak light has become a key factor restricting the production of greenhouse fruits and vegetables. Currently, the mainstream types of greenhouses include solar greenhouses and plastic greenhouses. Other types include: glass greenhouses, which have excellent light transmittance and are suitable for growing high-light plants; PC (polycarbonate) greenhouses, which are lightweight, prevent condensation, have good light transmission, and excellent heat preservation performance, and are often used in large-scale sightseeing greenhouses, seedling greenhouses, and flower markets; double-layer inflatable greenhouses, whose double-layer inflatable film design effectively prevents heat loss but reduces light transmittance, suitable for forestry, fruit trees, flowers, and vegetable seedlings and production; single-layer film multi-span greenhouses, whose main body is a hot-dip galvanized steel frame, with a single-layer film covering the top and sides, have a long service life and are widely used in the cultivation of vegetables, fruits, flowers, and other crops; and single-arch greenhouses, whose frame steel pipes use... Hot-dip galvanizing provides strong wind resistance, making it suitable for various crop cultivation and animal husbandry. Solar greenhouses offer good light transmission and insulation, are moderately priced, and offer significant energy savings, making them suitable for small-scale mechanized operations. They are primarily used for growing vegetables, fruits, and flowers, performing exceptionally well in cold seasons. Plastic greenhouses are inexpensive, easy to install and dismantle, provide excellent ventilation and light transmission, and have a long service life. Small arched greenhouses serve as shade structures, are simple to construct, require little investment, and are easy to manage. Double-slope greenhouses consist of two opposing slopes, with the top capable of being covered with blankets for good insulation. Winter-warm solar greenhouses utilize the rear wall for heat absorption and nighttime heat dissipation, enabling vegetable overwintering in northern regions without heating, and are suitable for off-season vegetable cultivation.

[0003] Although there are various types of greenhouses, existing environmental control technologies for grape cultivation have many limitations. Regarding light, insufficient light intensity in greenhouses restricts grape photosynthesis, affecting sugar accumulation and fruit development, resulting in insufficient sweetness and poor color. Furthermore, grapes have significantly different light intensity and duration requirements at different growth stages, but existing light control methods are relatively simple and difficult to precisely match. Regarding temperature and humidity, grapes have different temperature requirements at budding, flowering, and fruiting stages. Currently, greenhouse temperature control relies heavily on manual experience, lacking precise automatic control mechanisms. Inability to adjust excessively high or low temperatures in a timely and accurate manner can easily lead to abnormal grape growth and increase the likelihood of pests and diseases. For example, high temperatures during flowering reduce pollen viability, affecting pollination and fertilization, while low temperatures can cause frost damage. Humidity management also presents problems. Excessive humidity easily leads to fungal diseases such as gray mold and downy mildew, while excessively low humidity affects grape water metabolism and photosynthesis. Existing greenhouse humidity control equipment is rudimentary, making it difficult to accurately control humidity and create a suitable environment. Furthermore, existing greenhouse environmental monitoring facilities have shortcomings. Sensors are poorly positioned, failing to collect comprehensive and accurate environmental data and creating monitoring blind spots. Moreover, various types of environmental data are isolated, lacking effective integration and analysis, making it difficult to achieve precise control based on comprehensive data.

[0004] Therefore, there is an urgent need for a comprehensive, accurate, and intelligent system that can monitor and integrate multiple environmental parameters in real time, achieve efficient and coordinated control of various devices, meet the special environmental needs of grapes at different growth stages, improve grape yield and quality, and reduce production costs and pest and disease risks. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an intelligent environmental control system for grape production facilities. This system employs multiple environmental sensors and is equipped with ventilation, shading, and humidification spray devices to monitor several key physiological parameters in real time, such as photon flux density at different gradients, temperature and humidity, carbon dioxide concentration, soil moisture, and photosynthetic potential. This improves the optimization value of environmental control targets. By extracting and analyzing the relationships between indicators related to the growth and development of grapes in the facility, based on light intensity, wind speed, and external ambient temperature, this comprehensive sensing method can more accurately reflect the actual habitat conditions for grape growth, overcoming the problem of inaccurate judgment of grape growth status caused by limited monitoring parameters in the past.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent environmental control system for grape production facilities includes: a greenhouse body, wherein multiple support frames for cultivating vines are arranged at certain intervals along its width inside the greenhouse body; an environmental monitoring device, including a temperature sensor, a humidity sensor, a light sensor, and a soil moisture sensor, wherein the soil moisture sensor is arranged at the bottom of the support frames, the temperature sensor and the humidity sensor are both arranged at the upper part of the support frames, and the light sensor is arranged at the upper part of the greenhouse body and above the support frames; a control device, which is electrically connected to the environmental monitoring device and is used to receive data from the environmental monitoring device; a ventilation device, which is arranged on the circumferential wall of the greenhouse body and electrically connected to the control device, and is used to allow air to circulate inside the greenhouse body and regulate the temperature; a shading device, which is arranged on the side wall of the greenhouse body and electrically connected to the control device, and is used to block sunlight from the outside of the greenhouse body from reaching the inside; and a humidifying spray device, which is arranged on the end wall of the greenhouse body and electrically connected to the control device, and is used to regulate the humidity inside the greenhouse body.

[0008] Furthermore, the support frame includes a plurality of support rods arranged vertically at certain intervals along the length of the shed, and a crossbar disposed on the top of the support rods, the crossbar connecting the plurality of support rods together.

[0009] Furthermore, the temperature sensor is a DBS18B20 model, which is arranged on the upper part of each of the support rods.

[0010] Furthermore, the humidity sensor is a model SHT30, which is evenly arranged on the crossbar at certain intervals.

[0011] Furthermore, the light sensor is a BH1750FVI model, which has a first light sensor and a second light sensor. The first light sensor is arranged in the middle of the top of the greenhouse, and the second light sensor is arranged above the plant canopy on the support frame.

[0012] Furthermore, the soil moisture sensor is an EC-5 model, which is placed on the soil at the bottom of the shed.

[0013] Furthermore, the humidifying spray device includes a frame, a high-pressure spray pipe disposed on the top of the frame, and a pump body connected to one end of the high-pressure spray pipe, wherein the spray generated by the high-pressure spray pipe is directed toward the interior space of the shed.

[0014] Furthermore, the ventilation device includes a first fan and a second fan. The first fan is disposed on the end wall of the shed to allow air to circulate inside the shed, and the second fan is disposed on the end wall and side wall of the shed to regulate the temperature inside the shed.

[0015] Furthermore, the sunshade device includes a rotating rod disposed on the side wall of the canopy, around which a sunshade curtain is wound, and a roller shutter motor for driving the rotating rod to rotate, so that the sunshade curtain can be unfolded and retracted.

[0016] Furthermore, the environmental monitoring device also includes a carbon dioxide sensor, which is installed on the side wall of the shed to monitor the carbon dioxide concentration inside the shed.

[0017] This utility model has the following advantages:

[0018] This utility model's intelligent environmental control system employs multi-parameter real-time monitoring. Specifically, it utilizes various high-precision sensors, such as temperature, light, humidity, soil moisture, and carbon dioxide sensors, distributed across different locations within the greenhouse to collect multi-dimensional environmental data in real time. For example, one temperature sensor is placed every 10 square meters, positioned at different plant heights and planting areas, to accurately acquire temperature information, providing a data foundation for precise control. CFD simulation analysis of the greenhouse interior is conducted, simulating temperature and humidity, carbon dioxide concentration fields, and light distribution, thereby determining the equipment layout. For instance, ventilation and shading devices are rationally arranged based on simulation results, improving control accuracy and creating a suitable environment for grape growth. Furthermore, the system's various devices work collaboratively, automatically adjusting according to environmental changes. For example, during high daytime temperatures, shading curtains are first deployed to reduce heat entry; if the temperature remains high, ventilation equipment is activated for cooling. At night, technologies such as ground source heat pumps are used to recover heat and maintain warmth, precisely meeting the environmental needs of grapes at each stage of growth.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figure 1 and Figure 2 This paper illustrates an embodiment of an intelligent environmental control system for grape production facilities. The system mainly includes a greenhouse 1, within which are installed environmental monitoring devices 2, ventilation devices 3, shading devices 4, humidifying spray devices 5, and control devices, forming an intelligent environmental control system. By extracting and analyzing data on light, wind speed, and external environmental temperature and humidity, the system identifies relevant indicators for grape growth and development. This comprehensive sensing method more accurately reflects the actual habitat conditions for grape growth, overcoming the previous problem of inaccurate judgments of grape growth status due to limited monitoring parameters. Furthermore, before arranging the equipment inside the greenhouse 1, mature computational fluid dynamics (CFD) technology is used to simulate and analyze the interior of the greenhouse 1, including temperature and humidity simulation, carbon dioxide concentration field simulation, and light distribution simulation, thereby determining the equipment layout. Commonly used CFD software includes ANSYS Fluent and COMSOL Multiphysics.

[0024] The greenhouse 1 adopts a frame structure, consisting of two opposing side supports and multiple arched rods bridging the two side supports. These arched rods, arranged together, form a convex roof, which, together with the side supports, constitutes a cuboid-shaped frame. A visual protective film is applied to this frame structure; materials such as polyvinyl chloride film, ethylene-vinyl acetate copolymer film, dimming film, and light-converting film can be used. Entrances 102 are provided on the end walls of the greenhouse 1 for easy access for personnel and equipment. Inside the greenhouse 1, multiple support frames 101 for cultivating grapevines 6 are spaced apart along its width. In this embodiment, there are four support frames 101 arranged side-by-side along the width of the greenhouse 1. Figure 2As shown, each support frame 101 includes multiple support rods 101a arranged vertically at intervals along the length of the shed 1, and a crossbar 101b set on the top of the support rods 101a. The crossbar 101b connects the multiple support rods 101a in series to provide support for the grapevines 6. The grapevines 6 grow by hanging around the support rods 101a and the crossbar 101b.

[0025] The number of canopies 1 can be configured as needed. In this embodiment, two canopies 1 are arranged side by side and separated by a shading device 4. The shading curtain 402 of the shading device 4 is adjusted to be opened or closed according to the internal environmental parameters of the canopy 1.

[0026] Reference Figure 2 The environmental monitoring device 2 includes a temperature sensor 201, a humidity sensor 202, a light sensor 203, and a soil moisture sensor 204, which are distributed in different positions inside the greenhouse 1. It enables real-time monitoring of multiple key physiological parameters such as photon flux density at different gradients, temperature and humidity, carbon dioxide concentration, soil moisture, and photosynthetic potential, and transmits the data to the control device, which in turn controls the on / off operation of the ventilation device 3, the shading device 4, and the humidifying spray device 5, providing the crop with the best growth environment and reducing the crop's dependence on pesticides during growth.

[0027] Temperature sensor 201 is used to monitor the temperature of the grape growing environment. Inside the greenhouse 1, temperature sensor 201 is arranged on support frame 101. Specifically, temperature sensor 201 is placed on the upper part of each support rod 101a, close to the plant 6, at a height of 1.2-1.5m above the ground, which is the height of the grape canopy. DBS18B20 model temperature sensor 201 is selected, with one sensor placed every 10 square meters and one sensor every 5m along the planting row. Typically, 10-15 temperature sensors 201 are installed inside greenhouse 1, and the number can be adjusted according to the area of ​​greenhouse 1 to ensure even distribution of temperature sensors 201 in the planting area for more accurate temperature data acquisition.

[0028] The humidity sensor 202 is a model SHT30, with a humidity accuracy of ±3%RH. Inside the greenhouse 1, the humidity sensor 202 is positioned on the upper part of the support frame 101. The humidity sensors 202 are evenly distributed at certain intervals on the crossbars 101b, located within the canopy layer of the plants 6. In terms of density, one humidity sensor 202 is typically installed every 20 square meters, generally for a total of four. However, the actual number will be flexibly adjusted according to the size of the greenhouse 1. In addition, to comprehensively monitor the humidity in different areas of the greenhouse, besides the sensors on the crossbars 101b near the plants 6, an additional humidity sensor 202 is installed in the center of the greenhouse, at each of the four corners, and at the ventilation opening 103. This layout ensures comprehensive, all-around monitoring of the humidity inside the greenhouse, providing reliable data support for the system's precise humidity control.

[0029] The light sensor 203 is a BH1750FVI model, with a measurement range of 0-65535 lux. The light sensor 203 includes a first light sensor 203a and a second light sensor 203b, which together monitor the light intensity inside and outside the greenhouse. The light sensors 203 are arranged on the upper part of the greenhouse body 1 and above the support frame 101. The first light sensor 203a is located in the middle of the top of the greenhouse body 1, and its main function is to measure the light intensity outside the greenhouse, thereby obtaining basic information about external light. The second light sensor 203b is arranged above the canopy of the plant 6 on the support frame 101, and is used to measure the actual light intensity received by the plant 6 inside the greenhouse. The specific number of light sensors 203 is determined according to the size of the greenhouse body 1. This arrangement ensures comprehensive and accurate acquisition of light information inside and outside the greenhouse, providing reliable data support for the system to intelligently adjust according to light conditions.

[0030] The soil moisture sensor 204 is an EC-5 model, a three-parameter soil sensor capable of simultaneously measuring soil moisture, conductivity, and temperature. This sensor is located in the soil 7 at the bottom of the greenhouse 1, specifically at the bottom of the support frame 101. The soil moisture sensors 204 are spaced according to the length of the support frame 101. Considering that grape roots are mainly distributed in the 0-30cm soil layer, sensors are arranged at a density of one sensor per 20 square meters, but the exact number will be adjusted based on the actual size of the greenhouse 1. This arrangement allows the system to accurately acquire soil moisture and other relevant parameters in the planting area, providing a scientific basis for controlling the growth environment of greenhouse grapes and meeting the soil conditions required for grape growth.

[0031] The environmental monitoring device 2 also includes a carbon dioxide sensor, which is installed on the side wall of the greenhouse 1 to monitor the carbon dioxide concentration inside the greenhouse 1, understand the gas composition of the grape growing environment, and ensure the normal photosynthesis of the grapes.

[0032] The control device (not shown in the figure) is electrically connected to the environmental monitoring device 2 and is used to receive data collected by the environmental monitoring device 2. The control device can be installed in a well-ventilated, dry, and easily maintained location inside the greenhouse 1, such as on the wall of the operating room. The control device includes an STM32 central controller, and each sensor is electrically connected to the central controller. For example, temperature, humidity, and light sensors 203 are connected to the RS485 interface of the STM32 central controller via an RS485 bus, soil moisture sensor 204 is connected to the ADC interface of the STM32 central controller via a shielded twisted-pair cable, and carbon dioxide sensor communicates with the STM32 central controller via Zigbee wireless transmission. Through this connection method, various data collected by the environmental monitoring device 2 can be transmitted to the control device for further regulation and management of the environment inside the greenhouse.

[0033] The ventilation device 3 is installed on the circumferential wall of the shed 1 and is connected to the control device circuit. Its main function is to promote gas flow inside the shed 1 and regulate the gas temperature. (Refer to...) Figure 1 The ventilation device 3 consists of a first fan 301 and a second fan 302. Two ventilation openings 103 are provided on the end wall of the shed 1, each containing a first fan 301, which is connected to the control device circuitry. For example, the first fan 301 is a DC24V electric ventilation fan (electric actuator), powered by a DC 24V switching power supply (5A). The GPIO outputs of the STM32 central controller (e.g., PA0, PA1) are connected to a dual-channel relay module (SRD-05VDC-SL-C), with the relay contacts connected to the positive and negative terminals of the electric actuator (DC 24V). The speed of the electric actuator is adjusted using PWM signals or limit switches in conjunction with timing control, thereby controlling the ventilation angle. Mechanical limit switches (normally open contacts) are installed at both ends of the ventilation window, connected to the GPIO inputs of the STM32 central controller to detect the "fully open" and "fully closed" states of the ventilation window. The relay module is powered by the controller's DC 5V output. The first fan 301 is mainly responsible for the airflow inside the shed 1.

[0034] The shed 1 has four mounting ports 104 on its end walls and side walls, two on the end walls and two on the side walls. Each mounting port 104 houses a second fan 302. For example, the second fan 302 may be a heater, whose operating signal is controlled by a high-power relay connected to the GPIO output of the STM32 central controller. The relay contacts directly control the power supply to the heater. The heater is separately connected to a 220V distribution box and equipped with a 16A air switch. The heater has a built-in overheat protection switch (normally closed contact), whose signal is connected to the GPIO to detect equipment malfunctions. The relay coil is powered by the controller's DC 12V. The second fan 302 is primarily used to regulate the temperature inside the shed 1. In embodiments not shown, heating devices such as electric heating wires or underfloor heating wires can be installed on the ground of the shed 1 or suspended at a suitable height inside the shed 1 to ensure uniform temperature distribution within the shed 1.

[0035] Based on the data collected by the temperature sensor 201, the control device sends an electrical signal to control the opening and closing of the first fan 301 and the second fan 302 in the ventilation device 3, thereby realizing the circulation of air and the regulation of temperature inside the shed 1.

[0036] Reference Figure 1 The shading device 4 is installed on the side wall of the greenhouse 1 and is connected to the control device circuit. Its main function is to block sunlight from entering the greenhouse. The shading device 4 mainly consists of a rotating rod 401, a shading curtain 402, and a roller shutter motor. The rotating rod 401 is located on the side wall of the greenhouse 1 and is wrapped with the shading curtain 402, which can be a shading net. A roller shutter motor is installed at one end of the rotating rod 401, which drives the rotating rod 401 to rotate, thereby opening and closing the shading curtain 402. In actual operation, when the temperature inside the greenhouse is too high, the control device will control the shading curtain 402 to open, thereby reducing solar radiation entering the greenhouse and lowering the temperature; when the temperature is suitable, the control device will control the shading curtain 402 to close, ensuring that the crops receive sufficient sunlight. For example, the forward and reverse control signals of the roller blind motor are connected to a double-pole double-throw relay group through the two GPIO outputs of the STM32 central controller. The motor's forward rotation (sunshade curtain 402 unfolds) and reverse rotation (sunshade curtain 402 retracts) are achieved by switching the motor phase lines through the relay contacts.

[0037] To adjust the roller blind speed, since the motor supports frequency conversion, a connection method similar to that used for fans is adopted, i.e., the frequency converter is controlled via PWM signals. To accurately monitor the roller blind's operating status, a 500-line / revolution photoelectric encoder is installed at the end of the roller shaft. Its A / B phase pulse signals are input to the controller's timer, allowing the calculation of the unfolded length of the sunshade 402. Simultaneously, NPN proximity sensors are installed at both ends of the roller shaft, with their signals connected to GPIO to sense whether the roller blind has reached the correct operating position. The roller blind motor receives AC220V power from the distribution box, the relay group is powered by the controller's DC12V, and the encoder's required DC5V power comes from the controller's voltage regulator module.

[0038] Reference Figure 1 The humidifying spray device 5 is installed on the end wall of the greenhouse 1 and connected to the control device via a circuit. The humidifying spray device 5 mainly consists of a frame 501, a high-pressure spray pipe 502, and a pump body. The frame 501 provides support, and the high-pressure spray pipe 502 is located at the top of the frame 501, with one end connected to the pump body. During operation, the pump body delivers liquid to the high-pressure spray pipe 502, and the spray generated by the high-pressure spray pipe 502 is directed directly towards the interior space of the greenhouse 1. For example, the liquid is atomized through a high-pressure spray solenoid valve, and then the atomized water mist is driven by a fan to flow within the greenhouse, thus uniformly distributing humidity throughout the greenhouse. The GPIO output of the STM32 central controller is connected to a single-channel relay (JQC-3FF), and the contacts of this relay are connected to the solenoid valve coil (DC24V). To ensure stable and compliant spray pressure, a pressure sensor (measuring range 0-1MPa) is installed before the solenoid valve, and its signal is input to the control device via an ADC for real-time monitoring of the spray pressure. The solenoid valve is powered by a DC24V switching power supply, providing it with stable operating power, while the relay module's required DC5V power is supplied by the control device. This allows the humidifying spray device 5 to effectively regulate the humidity inside the greenhouse under the control of the device, meeting the humidity requirements for grape growth.

[0039] In embodiments not shown, the system further includes an energy management device for monitoring the energy consumption of the intelligent environmental control system, including but not limited to the use of energy such as electricity and gas, and feeding the data back to the control device.

[0040] In embodiments not shown, the system also includes a power supply unit under normal circumstances, which uses a conventional power source to power all devices in the system. During special periods, such as power outages or unstable power supply, the power supply unit uses solar panels or rechargeable batteries as backup power. The solar panels are installed on the top of the greenhouse 1 to ensure that sunlight is received for photovoltaic power generation without affecting the normal light exposure of the crops inside the greenhouse.
