DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The present invention provides Figures 1 to 5 The ozone fumigation system for organic vegetable cultivation, shown in the figure, includes an ozone generation module consisting of ozone generators arranged in a circular array. Each generator is equipped with a fin-type heat dissipation structure, and the ozone concentration is adjustable from 0.1 to 5 ppm. This module can flexibly adjust the ozone concentration based on the needs of different vegetable cultivation and the greenhouse environment to achieve the optimal sterilization and pest control effect.

[0027] Intelligent Control Module: Integrating temperature and humidity sensors, light sensors, a spore trap, and a microcontroller, it dynamically adjusts ozone release cycles and dosage using a PID algorithm. Environmental factors such as temperature, humidity, and light, as well as the number of fungal spores, can affect vegetable growth and the occurrence of pests and diseases. This module precisely controls ozone release based on real-time monitoring data.

[0028] Gas Circulation Module: This module includes a multi-directional airflow fan and a honeycomb adsorption catalytic component to achieve uniform ozone diffusion and residual decomposition. This ensures that ozone is evenly distributed throughout the greenhouse to fully exert its effect, while also decomposing any residual ozone to prevent harm to vegetables and humans.

[0029] Safety protection module: Equipped with a MEMS ozone concentration monitor, an audible and visual alarm, and a self-locking power-off device, it cuts off power within 0.5 seconds when ozone concentration exceeds the standard. This ensures that measures can be taken quickly to prevent safety accidents when ozone concentration rises abnormally.

[0030] IoT interface module: supports 5G / Bluetooth dual-mode communication, synchronizes data to the cloud management platform, and supports remote control via mobile phone app. This allows users to monitor and operate the smokehouse system anytime, anywhere, improving management efficiency.

[0031] The ozone generation module adopts high-frequency high-voltage electrodes with adjustable electrode spacing (1-5mm) and a power density of 50-200W / m 3 The ozone generation efficiency is ≥90%, and it supports modular plug-and-play replacement and is equipped with a moisture-proof, insulated casing. The high-frequency, high-voltage electrode design improves ozone generation efficiency, and the adjustable electrode spacing adjusts ozone production according to actual needs. The modular plug-and-play replacement facilitates maintenance and upgrades, and the moisture-proof, insulated casing adapts to the humid environment of the greenhouse, ensuring safe and stable system operation.

[0032] The gas circulation module's guide fan features a biomimetic spiral blade design with an adjustable wind speed of 0.5-3 m / s. Combined with a deflector, it creates a laminar flow field, with an ozone distribution uniformity deviation of ≤5%. The adsorption catalytic component is a silicon nitride-manganese oxide composite porous material with a porosity gradient (80 μm at the inlet → 30 μm at the outlet), which decomposes residual ozone into oxygen and simultaneously decomposes pesticide volatiles. The biomimetic spiral blade and deflector design ensure more uniform ozone diffusion. The silicon nitride-manganese oxide composite porous material not only decomposes residual ozone but also adsorbs pesticide volatiles, further improving the greenhouse environment.

[0033] The intelligent control module has a built-in AI optimization algorithm, which generates a dynamic fumigation strategy based on historical disease data (fungal spore density, temperature and humidity fluctuations), including: when the spore capture device detects fungal spores greater than 100 / m 3 When the ozone concentration reaches 3 ppm, the enhanced fumigation mode is triggered (ozone concentration 3 ppm, lasting 30 minutes). Respond promptly to high fungal spore density and effectively inhibit the development of diseases. The frequency of fumigation is automatically adjusted according to the crop growth stage, once a week in the seedling stage and once every 3 days in the fruiting stage. Fumigation is arranged reasonably according to the characteristics and needs of vegetables at different growth stages to ensure the sterilization and pest control effect without affecting the growth of vegetables. The probability of disease outbreak is predicted through machine learning, and preventive fumigation is started 48 hours in advance. Take measures in advance to reduce the risk of disease outbreaks and minimize losses. There are many types of vegetable viruses, and the following are common ones: Cucumber mosaic virus (CMV): It can infect a variety of vegetables, such as cucumbers, tomatoes, and peppers. Diseased plants show symptoms such as mosaic, deformity, and dwarfing, seriously affecting the growth and yield of vegetables.

[0034] Tobacco mosaic virus (TMV): Common on vegetables like tomatoes and peppers. It can cause yellow-green mosaics on leaves. In severe cases, leaves can shrink and become deformed, and plant growth can slow.

[0035] Tomato yellow leaf curl virus (TYLCV): Primarily harms tomatoes. Infected plants suffer from stunted growth, yellowing and curling leaves, and poor fruit development, causing significant losses to the tomato industry.

[0036] Potato virus Y (PVY): This virus infects vegetables such as potatoes and peppers, causing mottling and mosaic on the leaves. In severe cases, it can lead to stunting and necrosis of the plants, affecting tuber yield and quality.

[0037] Turnip mosaic virus (TuMV): This virus commonly occurs in cruciferous vegetables such as cabbage, radish, and kale. Infected plants exhibit symptoms such as mosaic, wrinkling, and vein necrosis, reducing the quality and yield of the vegetables. All of these viruses are curable.

[0038] The system integrates a solar power unit, including flexible photovoltaic panels and lithium iron phosphate batteries, with a battery life of 72 hours or longer. The bracket features a quick-release snap-on structure that supports both vertical and horizontal installation, making it suitable for use in various locations, from private balconies to large-scale farms. The solar power unit is energy-efficient and environmentally friendly, with a long battery life. The quick-release snap-on structure and multi-directional mounting options make the system easy to install and adapt to the needs of vegetable cultivation at various scales and locations.

[0039] The ozone generator module's finned heat sink is constructed from a highly thermally conductive aluminum alloy. The fins are 0.5-2mm thick and spaced 3-8mm apart. This highly thermally conductive aluminum alloy quickly dissipates heat generated by the ozone generator. The appropriate fin thickness and spacing ensure excellent heat dissipation, ensuring the ozone generator operates in a stable temperature environment and extending its service life.

[0040] The intelligent control module's data storage unit uses a high-capacity solid-state memory chip, capable of storing at least 10 years of environmental monitoring data and fumigation strategy records. This high-capacity solid-state memory chip preserves important data from system operation over the long term, facilitating historical data query and analysis, and providing a basis for optimizing fumigation strategies.

[0041] The safety protection module's MEMS ozone concentration monitor has a detection accuracy of ±0.01ppm and a response time of ≤10 seconds. This high-precision detection and fast response time enable timely and accurate monitoring of ozone concentration changes within the greenhouse, ensuring the safety protection module can react quickly and guarantee safe system operation.

[0042] The IoT interface module supports both NSA and SA dual-mode 5G communications, and Bluetooth 5.0 and above. Dual-mode 5G networking adapts to diverse network environments, while Bluetooth 5.0 and above provide more stable and efficient short-range communication, ensuring reliable data transmission between the system and the cloud management platform and mobile app.

[0043] The solar power supply unit's flexible photovoltaic panels have a photoelectric conversion efficiency of ≥20%, and the lithium iron phosphate battery has a charge-discharge cycle capacity of ≥2000. This high photoelectric conversion efficiency improves solar energy utilization, while the lithium iron phosphate battery's high charge-discharge cycle capacity ensures a long service life for the power supply unit and reduces operating costs.

Smart Policy Settings: Seedling stage (0-30 days): ozone concentration 0.4-0.45ppm, once a week, 3 minutes each time; Fruiting period (30-90 days): ozone concentration 0.4-0.45ppm, once every 3 days, 3 minutes each time; Disease warning threshold: spore density > 80 / m 3 The enhanced fumigation (concentration 3ppm, duration 10 minutes) is triggered.

[0052] Collaborative control strategy: When the spore density detected in a certain area is greater than 150 / m 3 When the fumigation is started, the three adjacent units will be linked to strengthen the fumigation synchronously; Cloud-based AI analyzes historical data and dynamically optimizes fumigation schedules across the entire base.

[0053] Solar power supply: One 20kW photovoltaic array is configured for every 5 mu, with an average daily power generation of 240kWh.
