Description

Technical Field

[0001] This invention belongs to the field of plant cultivation technology, and more specifically, relates to an intelligent aeroponic planting system based on pulsed low-temperature plasma. Background Technology

[0002] Plasma is considered the fourth state of matter, after solid, liquid, and gas, and is an electrically neutral substance composed of particles with various properties, such as cations, neutral particles, and free electrons. According to thermodynamic properties, plasma can be divided into two types: high-temperature plasma and low-temperature plasma. In low-temperature plasma discharge, although the electron temperature is high, the temperature of heavy particles such as ions and neutral particles is low, resulting in a low-temperature state for the entire system, close to room temperature.

[0003] Aeroponics, or simply aeroponics, is a novel cultivation method that uses a sprayer to atomize nutrient solution into tiny droplets, directly spraying them onto the plant roots to provide the water and nutrients needed for plant growth. This soilless cultivation technique allows crop roots to grow in the air, resulting in a significant increase in crop yield. It is a high-tech agricultural method that cultivates plants without soil or substrate. By artificially creating a root environment instead of soil, it effectively solves the contradictions in water, air, and nutrient supply that are difficult to address in traditional soil cultivation. This allows the crop roots to operate under optimal conditions, maximizing the crop's growth potential and greatly increasing plant growth and biomass. Aeroponics offers quality advantages that traditional soil cultivation and hydroponics lack, and is considered the most advanced soilless cultivation model, aligning with the future direction of agriculture.

[0004] During plasma discharge, abundant reactive oxygen and nitrogen particles are generated. Upon contact with water, the former produces a large amount of oxidizing substances, such as hydrogen peroxide and ozone, which can modify the seed surface, promote seed germination, sterilize and disinfect the root surface, and promote seed growth and development. The latter produces large amounts of nitrates, nitrites, and peroxynitrites, which can provide nitrogen fertilizer and stimulating factors for plant growth and development. Based on these characteristics, the combination of plasma and aeroponics technology has natural advantages.

[0005] In recent years, significant progress has been made in the research of plasma generating devices, and the connection between low-temperature plasma and agriculture has become increasingly close. However, most existing plasma devices remain at the theoretical and laboratory level, and there is still a gap between them and practical applications. Traditional low-temperature plasma equipment has a small processing area and limited gas flow rate, making it difficult to meet the processing needs of actual agricultural production. At the same time, the high temperature and high voltage in plasma can easily damage crops, and reasonable treatment methods are one of the problems that researchers in this field need to address. Developing high-flow-rate plasma generating devices and how to organically combine plasma treatment with aeroponic systems have become urgent problems to be solved in the application of low-temperature plasma in agriculture. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide an intelligent aeroponic planting system based on pulsed low-temperature plasma. The technical problem to be solved is how to organically combine low-temperature plasma with aeroponic technology in order to promote the growth and development of crops through a gentle means.

[0007] To achieve the above objectives, the technical solution adopted by this invention patent is as follows:

[0008] This invention provides an intelligent aeroponic cultivation system based on pulsed low-temperature plasma. The intelligent aeroponic cultivation system includes: a power supply module, a plasma module, an aeroponic cultivation module, a monitoring module, and a feedback regulation module. The power supply module provides a pulsed voltage to the plasma module, which in turn excites and maintains the low-temperature pulsed plasma to provide plasma activation mist to the aeroponic cultivation module. The monitoring module collects various parameters in the aeroponic environment in real time and transmits them to the feedback regulation module. The feedback regulation module compares the collected data with preset values ​​and sends control electrical signals to control the spray volume of the aeroponic cultivation module and the discharge intensity of the plasma module.

[0009] The power supply module includes an AC generation unit and a pulse generation unit. The AC generation unit receives 220V AC mains input. First, a full-bridge rectifier circuit converts the AC to DC. Then, a DC-DC circuit is used for voltage regulation and power factor correction. Finally, a full-bridge inverter circuit modulates the frequency and converts the DC back to AC. The pulse generation unit uses the output of the AC generation unit as its input. First, a Cockcroft-Walton circuit rectifies and multiplies the input AC to high-voltage DC. An air spark gap then converts the high-voltage DC into a pulse current. The air spark gap acts as a switching device, switching within nanoseconds and opening when the voltage reaches a certain threshold, generating the required pulse voltage. Adjusting the resistor and capacitor parameters in the circuit allows for precise control of the pulse frequency and width within a certain range. Preferably, the AC generation unit and the pulse generation unit are composed of printed circuit boards encapsulated in a metal casing. The output of the power supply module is connected to the plasma module to provide a suitable pulsed electric field, exciting and maintaining the pulsed cryogenic plasma.

[0010] The plasma module includes metal wire electrodes, metal plate electrodes, and an insulating frame. The metal wire electrodes are connected to the high-voltage output terminal of the power module, and the metal plate electrodes are connected to the ground electrode output terminal of the power module. When activated, it can quickly generate a large-volume plasma space region between the wires and the plate. Water mist passing through the plasma region will be rapidly activated into plasma-activated mist by the charged particles and electromagnetic fields within it, which is used to promote the germination and growth of plants.

[0011] Beneficial effects: This invention provides an intelligent aeroponic planting system based on pulsed low-temperature plasma. It is driven by a low-cost, compact, fast-leading, steep-pulse high-voltage pulse power supply. Through the alternating structure of the wire plates, a uniformly dispersed spatial plasma region is formed, achieving a processing efficiency far higher than that of traditional plasma devices.

[0012] The aeroponic planting module includes an atomization unit, an atomization treatment box, an aeroponic chamber, a crop planting unit, and an outer shell. The atomization unit includes an atomizer, atomization pipes, and a liquid level sensor. The atomization treatment box houses the plasma module and provides space for plasma to process water mist and generate plasma-activated mist. The aeroponic chamber provides the aeroponic environment for plant growth and development. The crop planting unit is the smallest unit for plant cultivation, and a single crop planting unit can only provide a growth and development environment for one plant at most. The outer shell includes the overall shell structure of the device and other support structures that connect the various structures.

[0013] Preferably, the aeroponic chambers are connected to each other or to the atomization treatment box via connecting pipes; the aeroponic chambers are equipped with vents and drainage pipes. Optionally, a fan can be added outside the vents to quickly drain the water mist inside the aeroponic chamber. The drainage pipes are used to clean the aeroponic chamber and quickly discharge waste liquid. Preferably, the aeroponic chamber is equipped with a settling tank to collect the liquid condensed from the water mist, which can be used for recirculation or discharge.

[0014] Preferably, the plasma module is built into the atomization treatment box, and the plasma-activated mist is introduced into the aeroponic chamber through the connecting pipe. The atomizer provides an aerosol cultivation environment for the aeroponic planting module. The atomization pipe is connected to the crop planting unit. After the water mist is sprayed out by the atomizer, it is transported to the atomization treatment box through the atomization pipe, activated by the plasma module, and then introduced into the aeroponic chamber. The liquid level sensor can monitor the liquid deposited in the aeroponic chamber in real time. If too much liquid is deposited, the atomizer can be adjusted to reduce the spray volume or turn off the atomizer. At the same time, the drainage pipe is opened to drain the excess liquid.

[0015] Preferably, multiple crop planting units can be installed on the outer casing, and the number of crop planting units that a single outer casing can hold can depend on the user's needs; multiple outer casings can also be connected to each other to provide the same aeroponic environment for multiple plants to be cultivated together, and the number of such units can depend on the number of plants that the user wants to plant.

[0016] Preferably, the outer casing can be disassembled and reassembled to facilitate internal cleaning.

[0017] The monitoring module is fixed inside the aeroponic chamber. The monitoring module includes one or more sensors such as a temperature sensor, humidity sensor, pH sensor, and salinity sensor, as well as a data storage unit, to monitor and record parameters of the plant's growth environment in real time.

[0018] Beneficial Effects: This invention provides an aeroponic system organically integrated with a plasma device. It utilizes the activating effect of active substances in the plasma on seeds, improving germination rate; it also utilizes the beneficial stimulation of these active substances during plant growth, promoting nutrient absorption and enhancing plant resistance, thereby increasing aeroponic yield; it monitors and provides real-time feedback on various environmental parameters of the aeroponic environment, such as temperature, humidity, light, and pH, dynamically adjusting spray volume and plasma discharge intensity. By comparing real-time parameters with preset standard parameters, it adjusts spray volume, plasma module on / off time, and plasma module discharge intensity in real time, achieving precise control over the plant growth process; and by adding drainage pipes, it enables the recycling of nutrient solution, reducing nutrient loss and lowering the cost of aeroponic cultivation.

[0019] The feedback adjustment module includes a data analysis unit and a control unit. Further, the data analysis unit includes a data transmission interface and a microprocessor, with the microprocessor electrically connected to the data transmission interface. During operation, the data transmission interface transmits the data collected by the monitoring module to the microprocessor. The microprocessor compares and analyzes the obtained data with preset empirical data items for the plant, and then transmits the analysis results to the control unit. The control unit then issues control commands to adjust the power supply module and the atomization unit in the aeroponic planting module.

[0020] In general, compared with the prior art, the above-described technical solutions conceived by this invention can achieve at least the following beneficial effects:

[0021] (1) This invention organically combines a plasma generator with a fog cultivation module, and proposes a fog cultivation system based on low-temperature pulsed plasma. The system activates the fog with a large flow of plasma, providing sufficient active substances for seed germination and plant growth and development.

[0022] (2) The present invention provides a low-temperature pulsed plasma generator under atmospheric pressure, which can excite and maintain a large volume of low-temperature pulsed plasma at normal temperature and pressure, and can quickly and extensively process water mist to obtain a large flow of plasma-activated mist. Compared with traditional plasma generators, it has higher processing efficiency.

[0023] (3) This invention uses multiple sensors to monitor and feedback various parameters of the aeroponic environment in real time. By comparing with preset values, the spray volume, fan volume and power module output are dynamically adjusted to achieve closed-loop control and self-regulation of the aeroponic system operation, thereby accurately controlling various parameters of the system operation and thus achieving precise control of the plant growth process.

[0024] (4) This invention provides a low-cost, compact, steep-pulse power supply solution. Compared with traditional pulse power supplies, it has a smaller size and lower manufacturing cost, while being able to drive the discharge of the plasma module in this invention, providing an efficient and stable power supply method.

[0025] (5) The present invention uses activated fog treated with low-temperature plasma to treat the surface of plants, including but not limited to the leaves, stems, roots and other organs of the plants, replacing the treatment method of directly contacting the plants with plasma, thus avoiding the damage to the plant surface that may be caused by direct contact of plasma with the plants; at the same time, the plasma activated fog droplets are small in size, providing sufficient oxygen concentration for the plant roots, thus avoiding root rot caused by lack of oxygen.

After passing through the plasma region, the water mist is activated by charged particles and electromagnetic fields, becoming plasma-activated mist, which is used to promote the germination and growth of plants.

[0037] Figure 3 This diagram illustrates a combination of a power module 1, a monitoring module 4, a plasma module 2, and an aeroponic cultivation module 3 according to an embodiment of the present invention. The aeroponic cultivation module includes an atomization unit 313, an atomization treatment box 302, an aeroponic chamber 307, a crop planting unit 311, and a housing 310. The atomization unit 313 includes an atomizer 314, an atomization pipe 301, and a liquid level sensor 315. The atomization treatment box 302 houses the plasma module and provides space for plasma treatment of water mist to generate plasma-activated mist. The crop planting unit 311 is the smallest unit for plant cultivation, providing a growth and development environment for a maximum of one plant per unit. The housing 310 includes the overall housing structure of the device and support structures connecting other structures.

[0038] In one specific example, the other end of the atomizing pipe 301 is connected to the atomizer 314 to provide a water mist environment for the aeroponic planting module 3.

[0039] In a specific example, the atomization treatment box 302 houses the plasma module 2, which is the primary site for the plasma to process water mist into plasma-activated mist. Preferably, the water mist passes from top to bottom through the plasma module 2, which is driven by the power module 1. Its high-voltage output terminal is connected to the metal wire electrode 202, and its ground electrode output terminal is connected to the metal plate electrode 201.

[0040] Preferably, the crop planting unit 311 includes a culture medium 305 and a planting plate 306. The plant 304 is fixed on the planting plate 306 by the culture medium 305, and its roots are suspended in the aeroponic chamber 307 by the culture medium 305 to fully absorb water mist and active nutrients in the environment.

[0041] Preferably, the monitoring module 4 is fixed inside the aeroponic chamber 307 and includes sensors 401 such as temperature sensors, humidity sensors, pH sensors, and salinity sensors, and a data storage unit 402. Data collected by one or more of these sensors is transmitted to the feedback adjustment module via the data transmission interface. The microprocessor in the data analysis unit compares the data with preset data and transmits the analysis results to the control unit. The control unit then issues control commands to adjust the power supply module 1 and the atomization unit 313 in the aeroponic planting module 3, thereby achieving real-time control of the low-temperature plasma discharge intensity and spray volume.

[0042] Preferably, the aeroponic chamber 307 is equipped with a ventilation opening 308 connected to an external fan for periodic cleaning and ventilation of the interior of the aeroponic chamber 307. Preferably, a settling tank 303 is provided below the aeroponic chamber 307 for collecting the plasma-activated mist condensed and deposited in the aeroponic chamber 307; preferably, a liquid level sensor 315, a liquid level signal line 316, and a drainage pipe 309 may be provided for real-time monitoring of the liquid level in the settling tank 303 to prevent excessive liquid accumulation. Preferably, the drainage pipe 309 is opened when the accumulated liquid reaches a preset level to discharge or recycle the plasma-activated mist condensate.

[0043] Figure 4This illustration shows the structure and operation of an atomizing unit provided in one embodiment of the present invention. The atomizing unit 313 includes an atomizer 314, an atomizing conduit 301, and a liquid level sensor 315. Preferably, the atomizing unit provides an aerosol environment for the entire aeroponics system. One end of the atomizing conduit 301 is connected to the atomizer 314, and the other end is connected to the atomization processing chamber 302. Water mist is introduced into the atomization processing chamber 302 through the atomizer 314. Preferably, the spray diameter of the atomizer 314 should be 0-2 μm. A smaller droplet size is beneficial for increasing the specific surface area of ​​the water mist, promoting a full reaction between the droplets and the plasma, and allowing the droplets to be more fully processed when passing through the plasma space region. Preferably, the spray flow rate of the atomizer 314 can be flexibly customized according to actual needs.

[0044] Furthermore, the liquid level sensor 315 and the control unit can control the atomizer 314, reducing the spray volume or turning off the atomizer 314 when there is a lot of liquid accumulation in the atomization chamber 307 or the ambient humidity exceeds a preset value.

[0045] Figure 5 A three-dimensional schematic diagram of the crop planting unit 311 and a schematic diagram of its connection with the outer shell are shown. Preferably, the culture medium 305 can be flexibly selected according to different plants, has a diameter of 8 cm, and has a slot on its outside for easy connection with the planting plate 306, with one culture medium 305 fixed on one planting plate 306.

[0047] Figure 6The figure shows the concentration of the main active substances in the droplets after being processed by the intelligent aeroponic colonization system provided in this embodiment of the invention. As shown in the figure, the droplets sprayed by the atomizer 314 are effectively activated after passing through the plasma module 2. The representative active substances are mainly nitrate ions, nitrite ions, hydrogen peroxide, and ammonium ions. When the intelligent aeroponic colonization system provided in this embodiment of the invention is operating normally, the water mist passes through the plasma module 2, is condensed and collected, and the concentrations of various active substances are measured. The concentration of nitrate ions can reach 2.7820 μmol / mL, the concentration of nitrite ions can reach 0.3260 μmol / mL, the concentration of hydrogen peroxide can reach 0.5147 μmol / mL, and the concentration of ammonium ions can reach 0.1100 μmol / mL. The ammonium, nitrate, and nitrite ions in this system can serve as nitrogen fertilizer during plant growth and development, promoting stem and leaf growth and enhancing plant resistance and growth potential. Nitrate ions can act as signaling molecules in the early stages of plant growth and development, promoting early seed germination and root formation. The bactericidal and disinfectant effects of nitrite and peroxynitrite ions can eliminate harmful bacteria and viruses on the plant surface, providing a safe and healthy growth environment. Appropriate concentrations of hydrogen peroxide can soften the seed coat during the early stages of seed growth, modifying the seed surface and promoting germination. After processing by the intelligent aeroponic planting system provided in this invention, the active substances within the droplets reach a suitable concentration, becoming nutrients that promote plant growth and development.

[0048] See Figures 7-8 Experiments were conducted on the intelligent aeroponic planting system provided in this embodiment of the invention. Mung bean plants were selected for the experiment. Both the experimental and control groups underwent three independent replicates. Each replicate included 15 mung bean seeds with smooth skin, plump kernels, and a weight difference of less than 5%. These seeds were cultivated under the same experimental environment for seven days, and the results were observed after seven days. The experimental group consisted of mung bean seeds cultivated using the intelligent aeroponic planting system provided in this embodiment of the invention. The plasma module was activated for 15 minutes daily, using plasma-activated mist to cultivate the mung bean seeds; the remaining time was spent cultivating with pure water mist. The control group used a standard aeroponic environment, with the same growth conditions as the experimental group. The experimental results showed that the average stem length of the mung bean plants cultivated in the control group (using the standard aeroponic system) was 25.339 cm, while the average stem length of the mung bean plants cultivated in the experimental group (using the system provided in this embodiment of the invention) was 27.23 cm, representing an average increase of 7.46%. The average leaf area of ​​the mung bean plants cultivated in the control group was 2.25 cm². 2 The average leaf area of ​​the mung bean plants cultivated in the experimental group was 2.719 cm². 2The average leaf area increased by 20.84%. The control group's mung bean plants had an average initial dry weight of 63.94 mg and an average fresh weight of 303.06 mg on the third day, a net increase of 239.12 mg. The experimental group's mung bean plants had an average initial dry weight of 69.26 mg and an average fresh weight of 330.66 mg on the third day, a net increase of 261.394 mg. Compared to the control group, the experimental group showed a net increase of 9.31%. These experimental data demonstrate that the intelligent aeroponic planting system provided in this embodiment of the invention can increase the stem length and leaf area of ​​the cultivated plants, promote the water absorption capacity of the seeds and roots, and effectively enhance the germination and growth potential of the plants.
