Description

Technical Field

[0001] This utility model belongs to the field of cultivation device technology, specifically relating to a Phalaenopsis orchid cultivation device. Background Technology

[0002] Phalaenopsis orchids, as a high-value-added flower variety, occupy an important position in the ornamental flower market due to their elegant blooms and long flowering period. However, Phalaenopsis orchids have extremely demanding requirements for their growing environment, especially regarding temperature, humidity, light, and ventilation. In traditional greenhouse cultivation, environmental control often relies on manual experience or simple automated equipment, making it difficult to achieve precise and real-time control of environmental parameters. This results in unstable growth cycles, inconsistent quality, and even pests and diseases caused by abnormal environments, leading to economic losses.

[0003] The shortcomings of existing technology:

[0004] Insufficient environmental control capabilities: Traditional greenhouses rely heavily on manual experience to adjust the size of ventilation openings or cover with shade nets, lacking real-time monitoring and automated feedback mechanisms. For example, temperature and humidity sensors are only fixed at a certain point inside the greenhouse, failing to reflect spatial heterogeneity (such as temperature differences between the top and bottom, and humidity differences between the sides and the center), leading to delayed or excessive control; shade nets need to be manually opened and closed, making it difficult to dynamically adjust their opening based on light intensity.

[0005] Poor ventilation efficiency and uniformity: Most existing greenhouse ventilation openings are fixed or semi-open designs (such as side roller blinds and top sliding windows), which limit the range of ventilation area adjustment and result in uneven airflow organization. For example, when the top ventilation opening is open, cold air sinks directly, which can easily cause local low temperatures; if the side ventilation opening is not high enough, it can easily form "dead zones", resulting in uneven distribution of humidity and CO2 concentration, which affects the uniformity of plant growth.

[0006] In recent years, the development of the Internet of Things (IoT) and artificial intelligence (AI) technologies has provided new solutions for facility agriculture. By integrating multi-parameter sensors (temperature, humidity, light, CO2, etc.), automated actuators (electric dampers, drip irrigation systems), and intelligent control algorithms, real-time monitoring, dynamic regulation, and precise management of environmental parameters can be achieved. However, current intelligent devices for Phalaenopsis orchid cultivation still have the following gaps:

[0007] Insufficient multi-parameter coordinated control: Existing systems mostly design control logic for single environmental factors (such as temperature or humidity), lacking a comprehensive response mechanism for the coupled effects of multiple factors such as temperature, humidity, rain, and snow. For example, in rainy or snowy weather, ventilation openings need to be closed to prevent rainwater from entering, but if excessively high humidity is detected inside the shed at the same time, traditional systems may fail to control the system due to logic conflicts.

[0008] The ventilation structure design is simple: most existing ventilation devices adopt a single-direction (top or side) air vent design, which makes it difficult to achieve three-dimensional airflow organization; the baffle adjustment relies on manual or simple motor (13) drive, and the opening control accuracy is low (such as only being able to achieve "fully open" or "fully closed"), and the ventilation area cannot be dynamically adjusted according to temperature and humidity deviation. Utility Model Content

[0009] To address the above problems, the purpose of this utility model is to provide a Phalaenopsis orchid cultivation device to solve the problems mentioned in the background art.

[0010] This utility model provides a Phalaenopsis orchid cultivation device, including a greenhouse structure module, which consists of a frame structure and a covering layer installed on the frame structure to form a cultivation chamber; an environmental monitoring module, including an array of temperature and humidity sensors distributed on the top and sides of the greenhouse, for real-time collection of temperature and humidity data at different heights and areas within the greenhouse; a protection sensing module, including a rain and snow sensor and a photoelectric sensor installed on the top of the greenhouse, for monitoring rain and snow weather and ambient light intensity, respectively; and a ventilation module, including: a top ventilation unit, consisting of multiple first ventilation openings and corresponding first baffles on the top of the greenhouse, the first baffles being movably connected to the greenhouse to adjust the opening degree of the first ventilation openings; a side ventilation unit, consisting of multiple second ventilation openings and corresponding second baffles on the sides of the greenhouse, the second baffles being movably connected to the greenhouse to adjust the opening degree of the second ventilation openings; and a control module, electrically connected to the environmental monitoring module, the protection sensing module, and the ventilation module, for receiving sensor data and dynamically controlling the operating status of the first and second ventilation opening units based on preset thresholds and algorithm logic.

[0011] Preferably, the first baffle is hinged to the U-shaped frame at the top of the shed via a pin, and one end of the pin is connected to a motor, which drives the pin to rotate along the U-shaped frame to adjust the opening of the first vent.

[0012] Preferably, two second baffles are symmetrically arranged at the second vent. Each of the two second baffles is equipped with an electric telescopic rod at one end that is far apart from the other. The electric telescopic rod drives the second baffles to slide along the track installed on the shed body to realize the opening and closing of the second vent and the adjustment of the opening degree.

[0013] Preferably, when the temperature and humidity in any area of ​​the greenhouse exceed a preset threshold, the control module drives the first baffle and / or the second baffle of the first vent to open, and dynamically adjusts the opening degree according to the temperature and humidity deviation.

[0014] When the rain and snow sensor detects a rain and snow signal or the photoelectric sensor detects that the light intensity is lower than a preset threshold, the control module closes the first and second baffles.

[0015] When the temperature and humidity inside the shed return to a safe range, the control module reduces the opening of the first or second vent to a preset minimum value or closes it.

[0016] Preferably, the first baffle is a solar baffle, which absorbs solar energy and converts it into electrical energy to power the electrical equipment inside the greenhouse.

[0017] Preferably, an angle detection device is installed on the output shaft of the motor. The angle detection device is used to detect the rotation angle signal of the motor and transmit it to the control module. The control module determines the opening degree of the first vent based on the angle signal detected by the angle detection device.

[0018] Preferably, a distance sensor is installed on one of the second baffles in each of the second vents. The distance sensor is used to monitor the distance signal between the two second baffles in real time and transmit it to the control module. The control module determines and adjusts the opening of the second vent based on the distance signal monitored by the distance sensor.

[0019] The beneficial effects of this invention are as follows: By deploying temperature and humidity sensor arrays on the top and sides of the greenhouse, real-time temperature and humidity data at different heights and in different areas are collected. Combined with the algorithm logic of the control module, the opening of the top and side ventilation openings can be dynamically adjusted. This avoids blind spots in single-location monitoring, accurately captures changes in the microenvironment inside the greenhouse, and, combined with the dual-channel design of the top and side ventilation units, the control module can dynamically adjust the opening of the ventilation openings at different locations according to temperature and humidity deviations, forming a three-dimensional ventilation airflow to quickly balance the temperature and humidity inside the greenhouse and avoid stress on the growth of Phalaenopsis orchids caused by drastic fluctuations in the local environment. For example, when the temperature and humidity in a local area exceed the standard, the ventilation opening in the corresponding area is opened first to quickly balance environmental parameters, preventing poor plant growth or the proliferation of pests and diseases due to abnormal local environments, significantly improving the consistency and quality stability of Phalaenopsis orchid growth, and reducing losses caused by environmental fluctuations; when the temperature and humidity in any area exceed the preset threshold, the system automatically opens the corresponding ventilation opening; after the temperature and humidity return to a safe range, the opening is reduced to the minimum value or closed, achieving ventilation on demand, reducing energy waste while maintaining environmental stability.

[0020] Rain and snow sensors on the top of the greenhouse monitor precipitation signals in real time, triggering the control module to close all ventilation baffles to prevent rainwater from directly wetting the plants or causing a sudden increase in humidity inside the greenhouse.

[0021] Photoelectric sensors detect ambient light intensity. When the light intensity is below a preset threshold, the vents are closed to reduce heat loss. In strong sunlight, the vents can be opened appropriately to balance the temperature inside the greenhouse and prevent leaf burn. Rain, snow, and light sensors work together to ensure that protective logic is prioritized in extreme weather conditions, preventing environmental out-of-control situations caused by misjudgment from a single sensor.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] Existing cultivation devices have the following drawbacks: Traditional greenhouse ventilation openings typically use a fixed opening or manual adjustment, which cannot be dynamically adjusted according to environmental parameters. For example, in high-temperature and high-humidity environments, insufficient ventilation opening may lead to air stagnation inside the greenhouse, causing mold growth; while in low-temperature or rainy / snowy weather, if the ventilation openings are not closed in time, heat loss or frost damage to plants may occur. Furthermore, the symmetrical baffle design of side ventilation openings, without precise distance monitoring, may lead to inaccurate opening control, further reducing ventilation efficiency. Simultaneously, traditional greenhouses lack active protection mechanisms in rainy / snowy or strong sunlight weather. For example, if ventilation openings are not closed in time during rainy / snowy weather, rainwater may seep into the greenhouse, damaging plants or equipment; and under strong sunlight, if the ventilation openings cannot be dynamically adjusted to balance light and ventilation needs, the temperature inside the greenhouse may become excessively high or plants may suffer from light stress.

[0030] Based on the above problems, the present invention adopts the following improvement method to solve them.

[0031] like Figure 1-5As shown, a Phalaenopsis orchid cultivation device includes a cultivation chamber 3 consisting of a frame structure 1 and a covering layer 2 installed on the frame structure 1. The frame structure 1 can be made of steel or aluminum alloy. The covering layer 2 is made of PC polycarbonate sheet or ETFE film with adjustable light transmittance. The good light transmittance of the PC sheet can meet the light requirements of Phalaenopsis orchids at different growth stages, promoting photosynthesis. The diffused light environment created by the PC sheet can avoid excessive local light, allowing all parts of the Phalaenopsis orchid to receive relatively soft and uniform light, reducing growth differences caused by uneven light, and promoting the overall development of the plant. At the same time, the surface is coated with an anti-ultraviolet coating, which can effectively block ultraviolet rays from damaging the sheet and slow down the aging process. Long service life; a temperature and humidity sensor array is installed inside the cultivation chamber 3, evenly distributed on the top and sides of the chamber, to collect temperature and humidity data at different heights and in different areas within the chamber. The layout of the temperature and humidity sensor array is as follows: the top sensors are spaced ≤4 meters apart, and the side sensors are arranged in layers at heights of 0.5 meters, 1.5 meters, and 2.5 meters above the ground to capture the vertical temperature and humidity gradient within the chamber. The top sensors are staggered from the first vent 8 to avoid blocking sunlight. In addition, a rain and snow sensor 6 and a photoelectric sensor 7 are also installed on the top of the chamber. The rain and snow sensor 6 is an electronic device used to detect precipitation (including rain, snow, hail, etc.) by sensing the physical properties (such as conductivity, dielectric constant, or optical properties) of precipitation particles. The system converts precipitation signals into electrical signals for output, providing real-time precipitation monitoring data for the automated control system. A photoelectric sensor 7 (such as a silicon photovoltaic cell, photodiode, or phototransistor) is used to monitor ambient light intensity (unit: lux) in real time. The monitored light intensity data indirectly reflects diurnal variations. Working in conjunction with a rain / snow sensor 6 and a temperature and humidity sensor, it enables real-time monitoring of the Phalaenopsis orchid cultivation environment. A ventilation module is used to regulate the environment of the greenhouse. This ventilation module includes a top ventilation unit consisting of multiple first ventilation openings 8 at the top of the greenhouse and corresponding first baffles 9. The first baffles 9 are hinged to a U-shaped frame 12 at the top of the greenhouse via pins. One end of the pin is connected to a motor 13, which drives the pin along... The system includes a U-shaped frame 12 that rotates to adjust the opening of the first vent 8; it also includes a side ventilation unit consisting of multiple second vents 10 and corresponding second baffles 11 located on the side of the shed; two second baffles 11 are symmetrically arranged at the second vent 10; each of the two second baffles 11 is equipped with an electric telescopic rod 14 at one end that is far apart from each other; the electric telescopic rod 14 drives the second baffles 11 to slide along the track 16 installed on the shed to realize the opening and closing and opening degree adjustment of the second vent 10; and a control module that is electrically connected to the environmental monitoring module, the protection sensing module and the ventilation module, for receiving sensor data and dynamically controlling the operating status of the first vent 8 unit and the second vent 10 unit based on preset thresholds and algorithm logic.Specifically, when the temperature or humidity in any area of ​​the greenhouse exceeds a preset threshold, it indicates that the temperature or humidity inside the greenhouse is too high. The control module drives the first baffle 9 and the second baffle 11 of the first vent 8 to open, and dynamically adjusts the opening degree of the first vent 8 and the second vent 10 according to the temperature and humidity deviation. For example, in the initial state, the first vent 8 and the second vent 10 are fully opened to increase the speed of humidity or temperature adjustment inside the greenhouse. As the temperature and humidity decrease, the opening degree of the first vent 8 and the second vent 10 is reduced. In special cases, when the temperature sensor 4 or the humidity sensor 5 in any area of ​​the greenhouse exceeds the preset threshold and the rain and snow sensor 6 detects rain and snow signals or the photoelectric sensor 7 detects that the light intensity is lower than the preset threshold, it indicates that the weather is rainy or snowy, or at night, when the humidity will increase relatively. At this time, the control module controls the second vent 10 on the side of the greenhouse to open. When the temperature and humidity inside the greenhouse return to a safe range, the control module reduces the opening degree of the first vent 8 or the second vent 10 to the preset minimum value or closes it. To facilitate adjustment of the opening of the second vent 10, a distance sensor 15, such as an ultrasonic distance sensor 15 or a laser distance sensor 15, is installed on one of the second baffles 11 in each of the second vents 10. The distance sensor 15 is used to monitor the distance signal between the two second baffles 11 in real time and transmit it to the control module. The control module determines and adjusts the opening of the second vent 10 based on the distance signal monitored by the distance sensor 15. For example, when the second vent 10 is fully closed, the distance signal monitored by the distance sensor 15 is close to 0. When the control module receives the distance signal transmitted by the distance sensor 15, it analyzes the data from other sensors and adjusts the opening of the second vent 10 accordingly. As for monitoring the opening of the first vent 8, it can be determined based on the angle of rotation of the motor 13. The opening and closing of the vent is usually achieved by the motor 13 driving a mechanical structure (such as a gear, screw, connecting rod, or swing arm). If there is a fixed transmission ratio between the rotation angle of motor 13 and the opening degree of the vent (for example, a 180° rotation of motor 13 corresponds to the vent going from fully closed to fully open), the opening degree can be indirectly calculated by monitoring the angle of motor 13. Formulaic expression: ×100% (e.g., when motor 13 rotates from 0° to 180°, the corresponding vent opening changes from 0% to 100%). An angle detection device, such as an angle sensor, encoder, Hall sensor, or potentiometer, needs to be installed on the shaft of motor 13 or at the end of the transmission mechanism to provide real-time feedback on the rotation angle of motor 13.

[0032] Furthermore, such as Figure 1-2As shown, to save energy, the first baffle 9 can be a solar baffle. The solar baffle absorbs solar energy and converts it into electrical energy to power the electrical components (various sensors and motor 13) inside the greenhouse. When there is sufficient sunlight, solar power is used first to charge the energy storage battery; when there is insufficient sunlight, it switches to mains power or energy storage battery power. Combined with the angle detection device and the distance sensor 15, the control module can monitor the rotation angle of the solar baffle and the opening of the side baffles in real time to optimize the balance between power generation efficiency and ventilation needs. For example, when there is sufficient sunlight and the temperature and humidity inside the greenhouse are not too high, the angle of the solar baffle is adjusted first to maximize power generation, while the opening of the side vents is dynamically adjusted according to the temperature and humidity data.
