Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural intelligent control technology, and in particular to an intelligent temperature and humidity control method and system for the cultivation of Fritillaria cirrhosa. Background Technology
[0002] Fritillaria cirrhosa has significant effects in clearing heat and moistening the lungs, resolving phlegm and relieving cough. Its growth habits are extremely unique; it prefers cool, humid environments and dislikes high temperatures, high humidity, and drought. It requires extremely high stability in temperature and humidity during its growth. Currently, large-scale cultivation of Fritillaria cirrhosa is mostly concentrated in high-altitude areas. These areas are characterized by large diurnal temperature differences, uneven light intensity, dry air, and frequent temperature and humidity fluctuations, further increasing the difficulty of temperature and humidity control during Fritillaria cirrhosa cultivation.
[0003] In existing Fritillaria cirrhosa cultivation techniques, temperature and humidity control often employ a single-parameter independent control mode, meaning that temperature and humidity are monitored and adjusted separately without considering their mutual influence. Furthermore, the control process relies solely on numerical data collected by sensors, lacking intuitive monitoring and feedback of the actual growth status of the Fritillaria cirrhosa. Specifically, in existing technologies, temperature and humidity control operate independently. When the temperature exceeds a preset threshold, only cooling or heating equipment is activated, ignoring the indirect impact of temperature changes on air humidity. This easily leads to secondary anomalies such as "cooling leading to excessively high humidity" or "heating leading to excessively low humidity." Simultaneously, relying solely on sensor values to determine whether temperature and humidity are suitable makes it impossible to intuitively observe the actual growth status of the Fritillaria cirrhosa leaves and its growth pattern. It is difficult to detect problems where sensor values are normal but the plant has already shown abnormal growth, resulting in lag and bias in the control process. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent temperature and humidity control method and system for the cultivation of Fritillaria cirrhosa, aiming to achieve the effect of linking video monitoring and sensor data, taking into account the coordinated regulation of temperature and humidity, and ensuring that Fritillaria cirrhosa can obtain stable and suitable temperature and humidity conditions in the high-altitude planting environment.
[0005] To achieve the above objectives, the present invention employs an intelligent temperature and humidity control method for the cultivation of Fritillaria cirrhosa, comprising the following steps: Based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment, threshold values for core parameters of soil moisture, temperature and humidity, and irrigation equipment were set. Real-time soil moisture is collected, irrigation is started or stopped according to the moisture threshold, and abnormal irrigation conditions are monitored. When abnormal conditions occur, the moisture is stabilized by reducing the threshold difference. By linking video surveillance and sensor data, temperature and humidity can be controlled in a coordinated manner.
[0006] Among them, in the step of setting the core parameter thresholds for soil moisture, temperature and humidity, and irrigation equipment based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment: Based on the different growth habits of Fritillaria cirrhosa during the seedling stage, bulb enlargement stage, flowering stage, fruiting stage and dormancy stage, the range of soil moisture and air temperature and humidity for each growth stage was defined. In addition, considering the environmental characteristics of high-altitude areas with large diurnal temperature differences, uneven light intensity and dry air, the basic threshold values of each parameter were initially determined. Based on historical cultivation data of Fritillaria cirrhosa grown at high altitudes, and combined with the environmental differences at different altitude gradients, the initially defined basic thresholds were calibrated. Based on the characteristics of the irrigation equipment, such as its operating power, spray volume, and irrigation duration, set the start-stop threshold, operating time threshold, and intermittent cycle threshold for the irrigation equipment.
[0007] After setting the start-stop threshold, runtime threshold, and intermittent cycle threshold for the irrigation equipment based on its operating power, spray volume, and irrigation duration: The core thresholds for soil moisture, air temperature and humidity, and irrigation equipment parameters at each growth stage are summarized to form a complete threshold system.
[0008] Among them, the steps of real-time soil moisture collection, starting and stopping irrigation according to moisture thresholds, monitoring irrigation anomalies, and stabilizing moisture by reducing the threshold difference when anomalies occur are as follows: Soil moisture sensors were evenly deployed in the Fritillaria cirrhosa planting area, and soil moisture data were collected in real time at a preset frequency. It receives data transmitted from the soil moisture sensor in real time, compares the collected real-time soil moisture with the preset soil moisture threshold for the corresponding growth stage, and determines whether the current soil moisture is within a suitable range.
[0009] Among them, the step of receiving data transmitted from the soil moisture sensor in real time, comparing the collected real-time soil moisture with the preset soil moisture threshold for the corresponding growth stage, and determining whether the current soil moisture is within a suitable range is as follows: If the real-time soil moisture is lower than the preset lower threshold, an irrigation start command is triggered to start the irrigation equipment for irrigation operations. If the real-time soil moisture exceeds the preset threshold, an irrigation stop command is triggered, shutting down the irrigation equipment and stopping irrigation.
[0010] The process includes receiving data from a soil moisture sensor in real time, comparing the collected real-time soil moisture with preset soil moisture thresholds for the corresponding growth stage, and determining whether the current soil moisture is within a suitable range. During irrigation, the operating status of irrigation equipment and changes in soil moisture are continuously monitored. At the same time, abnormal irrigation situations such as blockage of irrigation pipelines, equipment shutdown, and abnormal irrigation volume are investigated, and abnormal signals are captured and reported.
[0011] In the step of coordinating temperature and humidity control by linking video surveillance and sensor data: Video monitoring equipment was installed in the Fritillaria cirrhosa cultivation greenhouse to monitor the planting area in full coverage. It was also used in conjunction with temperature and humidity sensors to collect real-time data on air temperature and humidity, as well as image data of the planting area. The collected temperature, humidity, and image data were analyzed simultaneously. Combined with the leaf condition and growth status of Fritillaria cirrhosa in the images, the rationality of temperature and humidity control was assessed.
[0012] Among the steps, the simultaneous analysis of collected temperature and humidity data and image data, combined with the leaf condition and growth status of Fritillaria cirrhosa in the images, helps to determine the rationality of temperature and humidity control: When either temperature or humidity exceeds a preset threshold, the system will coordinate and regulate the data based on their relationship. If the temperature is too high and the humidity is too low, the system will simultaneously activate cooling and humidifying equipment to lower the temperature and increase the humidity. If the temperature is too low and the humidity is too high, start the heating and dehumidification equipment simultaneously to increase the temperature and reduce the humidity.
[0013] Among these steps, after simultaneously analyzing the collected temperature, humidity, and image data, and combining this with the leaf condition and growth status of Fritillaria cirrhosa in the images to help determine the rationality of temperature and humidity control: During the control process, the growth status of Fritillaria cirrhosa is observed in real time through video monitoring. Combined with real-time temperature and humidity data fed back by sensors, the operating power and operating time of the control equipment are dynamically adjusted to optimize the control effect.
[0014] This invention also provides an intelligent temperature and humidity control system for the cultivation of Fritillaria cirrhosa, including a basic parameter setting module, a dynamic irrigation control module, and a temperature and humidity linkage control module; wherein: The basic parameter setting module is used to set the core parameter thresholds of soil moisture, temperature and humidity, and irrigation equipment based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment. The dynamic control irrigation module is used to collect soil moisture in real time, start and stop irrigation according to the moisture threshold, and monitor irrigation abnormalities. When an abnormality occurs, the moisture is stabilized by reducing the threshold difference. The temperature and humidity linkage control module is used to coordinate the control of temperature and humidity by linking video monitoring and sensor data.
[0015] This invention discloses an intelligent temperature and humidity control method and system for the cultivation of Fritillaria cirrhosa. The method comprises the basic parameter setting module, the dynamic irrigation control module, and the temperature and humidity linkage control module, which perform the following steps: Based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment, core parameter thresholds for soil moisture, temperature, humidity, and irrigation equipment are set; soil moisture is collected in real time, irrigation is started and stopped according to the humidity threshold, and abnormal irrigation conditions are monitored. When abnormal conditions occur, the threshold difference is reduced to stabilize humidity; video monitoring and sensor data are linked to achieve coordinated temperature and humidity control; through the above methods, the linkage between video monitoring and sensor data is achieved, and coordinated temperature and humidity control is considered, ensuring that Fritillaria cirrhosa can obtain stable and suitable temperature and humidity conditions in the high-altitude planting environment.

[0027] Please see Figures 1-4 This invention provides an intelligent temperature and humidity control method for the cultivation of Fritillaria cirrhosa, comprising the following steps: S100: Based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment, the core parameter thresholds for soil moisture, temperature and humidity, and irrigation equipment are set.
[0028] In this embodiment, based on the growth characteristics of Fritillaria cirrhosa and the high-altitude planting environment, threshold values for core parameters such as soil moisture, temperature and humidity, and irrigation equipment are set. The specific process is as follows: S101: Based on the different growth habits of Fritillaria cirrhosa seedlings, bulb enlargement, flowering, fruiting and dormancy, the range of soil moisture and air temperature and humidity for each growth stage is defined. In addition, based on the environmental characteristics of high-altitude areas with large diurnal temperature differences, uneven light intensity and dry air, the basic thresholds of each parameter are initially defined. S102: Based on historical cultivation data of Fritillaria cirrhosa grown at high altitudes, and combined with the environmental differences at different altitude gradients, the initially defined basic thresholds are calibrated. S103: Based on the equipment characteristics of the irrigation equipment, such as operating power, spray volume, and irrigation duration, set the start-stop threshold, operating time threshold, and intermittent cycle threshold for the irrigation equipment; S104: Summarize the core thresholds of soil moisture, air temperature and humidity, and irrigation equipment parameter thresholds for each growth stage to form a complete threshold system.
[0029] In the above process, the core growth requirements of Fritillaria cirrhosa at each growth stage were clarified: During the seedling stage, the plants are fragile and have poor resistance to adverse conditions, requiring moist soil and cool air to avoid drought and high-temperature stress. Therefore, the initial range for soil moisture during the seedling stage is 60%-75%, air temperature is 5℃-12℃, and air humidity is 60%-75%. The bulb enlargement stage is a critical stage for Fritillaria cirrhosa yield formation. Humidity needs to be appropriately controlled to prevent bulb rot, while ensuring suitable temperature to promote bulb enlargement. The initial range for soil moisture during this stage is 55%-70%, air temperature is 8℃-18℃, and air humidity is 55%-70%. During the flowering period, a stable temperature and humidity environment is needed to ensure pollination success. The preliminary range is defined as soil moisture 50%-65%, air temperature 10℃-20℃, and air humidity 50%-65%. During the fruiting period, both fruit development and bulb growth need to be considered. The temperature and humidity requirements are similar to those during the bulb enlargement period. The preliminary range is defined as soil moisture 55%-70%, air temperature 12℃-22℃, and air humidity 55%-70%. During the dormant period, plant growth stops, and a low-temperature and dry environment is required. The preliminary range is defined as soil moisture 40%-55%, air temperature -2℃-5℃, and air humidity 40%-55%.
[0030] Based on this, adjustments were made according to the environmental characteristics of high-altitude areas: to address the problem of large diurnal temperature differences, a diurnal temperature variation range was added to the air temperature range for each growth stage, with the nighttime temperature threshold lowered by 2-3°C compared to the daytime temperature to avoid nighttime frost damage; to address the problems of uneven light intensity and dry air, the basic threshold for daytime air humidity was appropriately increased by 1%-2% to compensate for the problem of excessive water evaporation when the light is strong, while the range of soil moisture fluctuations was appropriately reduced, and the basic thresholds for each parameter were initially defined to ensure that the basic thresholds can initially adapt to the high-altitude planting environment.
[0031] Historical cultivation data of Fritillaria cirrhosa grown on a large scale at high altitudes over the past 3-5 years were collected, including soil moisture and air temperature and humidity data at different altitudes (2000m-4000m) and different growth stages, as well as corresponding growth indicators such as Fritillaria cirrhosa survival rate, bulb yield, and medicinal quality, to establish a historical database. The historical data were categorized and statistically analyzed to examine the correlation between temperature and humidity, soil moisture, and Fritillaria cirrhosa growth indicators at different growth stages under different altitude gradients. For example, in areas above 3500m altitude, air temperatures are generally low, requiring an increase of 1℃-2℃ in the upper limit and 0.5℃-1℃ in the lower limit of the basic air temperature threshold at each growth stage to prevent low temperatures from affecting plant growth. In areas below 2500m altitude, daytime temperatures tend to be high in summer, requiring a decrease of 1℃-2℃ in the upper limit of the basic air temperature threshold and a decrease of 1%-2% in the basic air humidity threshold to prevent mold growth caused by high temperature and humidity.
[0032] Taking into account the environmental differences at different altitude gradients, the initially defined basic thresholds were calibrated one by one. Threshold ranges that were shown to cause abnormal growth of Fritillaria cirrhosa in historical data were removed, and the upper and lower limits of the thresholds were adjusted to ensure that the calibrated thresholds could be adapted to the high-altitude planting environment at different altitude gradients. At the same time, the correlation between the thresholds and the growth indicators of Fritillaria cirrhosa was improved, providing a more scientific basis for subsequent precise regulation.
[0033] Clearly define the core characteristics of the irrigation equipment used, including the spray volume corresponding to the equipment's operating power, the irrigated area per unit time, and parameters such as water penetration rate and coverage uniformity under different operating power levels. For example, the selected ultrasonic spray irrigation equipment has a spray volume of 5L / h and a coverage area of 10m² when operating at low power. 2 The water penetration rate is slow; when operating at high power, the spray volume is 15L / h, covering an area of 20m². 2 It allows water to penetrate quickly.
[0034] Based on the calibrated soil moisture thresholds for each growth stage, the start and stop thresholds for the irrigation equipment were set: the irrigation start threshold was consistent with the lower limit of the corresponding soil moisture threshold for the growth stage, i.e., irrigation was triggered when the soil moisture dropped to the lower limit; the irrigation stop threshold was slightly lower than the upper limit of the soil moisture threshold by 0.5%-1% to avoid over-irrigation and excessive soil moisture. Simultaneously, based on the equipment spray volume and water penetration rate, irrigation duration thresholds were set for different growth stages: during the seedling stage, when the plant's root system is shallow, the irrigation duration threshold was set to 10-15 minutes / time, using low-power operation; during the bulb enlargement stage, when the root system is well-developed, the irrigation duration threshold was set to 15-20 minutes / time, allowing for medium-high power operation; during the dormant period, irrigation needs to be controlled, and the irrigation duration threshold was set to 5-10 minutes / time, using low-power intermittent operation. Furthermore, based on the soil moisture evaporation rate, irrigation interval period thresholds were set: 24-48 hours for the seedling stage, bulb enlargement stage, and fruiting stage, and 72-96 hours for the dormant stage, ensuring that the irrigation equipment operation matches the soil moisture requirements and equipment characteristics.
[0035] The soil moisture, air temperature, and air humidity core thresholds for each growth stage after calibration in step S102 are categorized and organized according to the seedling stage, bulb enlargement stage, flowering stage, fruiting stage, and dormancy stage. The upper and lower limits of the thresholds for each parameter in each stage and the diurnal difference thresholds are clarified. At the same time, the irrigation equipment start-stop thresholds, running time thresholds, and intermittent cycle thresholds set in step S103 are organized and associated with each growth stage to clarify the standard operating parameters of irrigation equipment in different growth stages.
[0036] All threshold parameters are verified to ensure compatibility and consistency among them. For example, the irrigation volume corresponding to the irrigation equipment runtime threshold must be sufficient to raise soil moisture from the start threshold to the stop threshold without exceeding the upper limit of the core soil moisture threshold. Air temperature and humidity thresholds must be coordinated with soil moisture thresholds to align with the growth habits of Fritillaria cirrhosa. A complete threshold system is then established, clarifying the applicable scenarios, relationships, and calling rules for each threshold. This provides unified and precise standard support for subsequent control operations in steps S200 and S300, ensuring the entire control process is systematic, scientific, and standardized.
[0037] S200: Real-time soil moisture collection, irrigation start / stop based on moisture threshold, and monitoring for irrigation anomalies. When an anomaly occurs, the moisture level is stabilized by narrowing the threshold difference.
[0038] In this embodiment, soil moisture is collected in real time, irrigation is started and stopped according to a moisture threshold, and abnormal irrigation conditions are monitored. When abnormal conditions occur, the moisture level is stabilized by reducing the threshold difference. The specific process is as follows: S201: Soil moisture sensors are evenly deployed in the Fritillaria cirrhosa planting area to collect soil moisture data in real time at a preset frequency. S202: Receive data transmitted from the soil moisture sensor in real time, compare the collected real-time soil moisture with the preset soil moisture threshold for the corresponding growth stage, and determine whether the current soil moisture is within a suitable range; if the real-time soil moisture is lower than the preset lower threshold, trigger the irrigation start command to start the irrigation equipment for irrigation; if the real-time soil moisture is higher than the preset upper threshold, trigger the irrigation stop command to turn off the irrigation equipment and stop irrigation. S203: During irrigation, continuously monitor the operating status of irrigation equipment and changes in soil moisture, simultaneously investigate irrigation anomalies such as blockage of irrigation pipelines, equipment shutdown, and abnormal irrigation volume, capture abnormal signals and report them.
[0039] During the above process, soil moisture sensors were evenly deployed according to the area, planting density, and soil texture of the Fritillaria cirrhosa planting area, ensuring that the sensor spacing was reasonable, every 10-15m. 2 For areas with uneven soil texture or fluctuating temperature and humidity such as around irrigation equipment, deploy one sensor. For these areas, reduce the spacing between sensors and increase the number of sensors to ensure that the collected data can comprehensively and accurately reflect the soil moisture status of the entire planting area and avoid control deviations caused by uneven local soil moisture.
[0040] The soil moisture sensor uses a high-precision digital sensor to ensure that the acquisition accuracy error does not exceed ±1%, accurately capturing minute changes in soil moisture. The sensor is buried at a depth of 5-10cm, which matches the distribution depth of the Fritillaria cirrhosa root system, ensuring that the collected soil moisture data accurately reflects the water status of the plant's root environment. Simultaneously, the sensor's preset acquisition frequency is set and adjusted according to the growth stages of Fritillaria cirrhosa: the acquisition frequency is once every 10-15 minutes during the seedling, bulb enlargement, and fruiting stages to ensure timely capture of soil moisture changes; the acquisition frequency is once every 30 minutes during dormancy, balancing monitoring needs with energy conservation.
[0041] The system receives soil moisture data transmitted from various soil moisture sensors in real time. First, the data is preprocessed to remove invalid data caused by sensor malfunctions or signal interference, ensuring the accuracy and validity of the data. Then, based on the current growth stage of Fritillaria cirrhosa, the corresponding soil moisture core threshold set in step S100 is called, and the preprocessed real-time soil moisture data is compared with the threshold one by one to determine whether the current soil moisture is within a suitable range.
[0042] If, after comparison, it is found that the real-time soil moisture is lower than the lower limit of the soil moisture threshold for the corresponding growth stage, it indicates that the soil moisture is insufficient and cannot meet the growth requirements of Fritillaria cirrhosa. At this time, an irrigation start command is triggered. According to the current growth stage, the irrigation equipment operation parameter threshold set in step S100 is called to start the irrigation equipment in the corresponding area and carry out irrigation operation according to the preset operating power and irrigation duration. If the real-time soil moisture is higher than the upper limit of the soil moisture threshold for the corresponding growth stage, it indicates that the soil moisture is too much, which can easily lead to root rot and bulb mold. At this time, an irrigation stop command is triggered to immediately shut down all operating irrigation equipment and stop irrigation operation. If the real-time soil moisture is within the preset threshold range, no irrigation command is triggered and real-time monitoring continues.
[0043] After the irrigation equipment is started, it continuously links with the irrigation equipment and the soil moisture sensor to perform dual real-time monitoring: on the one hand, it monitors the operating status of the irrigation equipment, including parameters such as equipment operating power, running time, and spray uniformity, to determine whether the equipment is operating normally; on the other hand, it increases the acquisition frequency of the soil moisture sensor to once every 5 minutes to capture the changing trend of soil moisture in real time and monitor whether the soil moisture gradually increases towards the preset threshold range.
[0044] Simultaneously, various irrigation anomalies are investigated, with a focus on three core anomalies: First, irrigation pipeline blockage. By monitoring changes in the operating pressure of the irrigation equipment, if the pressure rises abnormally and the spray volume decreases significantly, it is determined to be pipeline blockage. Second, equipment shutdown. By monitoring equipment operation feedback signals, if the equipment stops operating before completing the preset irrigation time or there is no operation feedback, it is determined to be an equipment shutdown anomaly. Third, abnormal irrigation volume. By comparing the rate of change in soil moisture with the preset rate, if the soil moisture increases too quickly (exceeding the normal infiltration rate) or increases too slowly (almost no change), it is determined to be an abnormal irrigation volume.
[0045] Once any of the above abnormal signals are detected, immediately stop the current irrigation control operation and record the type of abnormality, the time of occurrence of the abnormality, the area of the abnormality, and the corresponding data (such as equipment pressure when blocked, soil moisture when shut down). The abnormal signal should also be fed back to the staff terminal to remind the staff to handle it in time. At the same time, activate the temporary stabilization mechanism to reduce the difference between the upper and lower limits of the soil moisture threshold at the current growth stage and reduce the suitable moisture range to avoid excessive fluctuations in soil moisture caused by abnormal situations. After the staff have investigated and resolved the abnormality, the normal irrigation control mode can be restored.
[0046] S300: Links video surveillance and sensor data to perform coordinated control of temperature and humidity.
[0047] In this embodiment, video surveillance and sensor data are linked to achieve coordinated control of temperature and humidity. The specific process is as follows: S301: Install video monitoring equipment in the Fritillaria cirrhosa cultivation greenhouse to monitor the planting area in full coverage, and use temperature and humidity sensors to collect real-time data on air temperature and humidity as well as image data of the planting area. S302: Simultaneously analyze the collected temperature, humidity, and image data, and combine the leaf condition and growth status of Fritillaria cirrhosa in the images to help determine the rationality of temperature and humidity control; when either temperature or humidity data exceeds the preset threshold, coordinate control is performed based on the correlation between the two. If the temperature is too high and the humidity is too low, cooling and humidifying equipment are activated simultaneously to lower the temperature and increase the humidity; if the temperature is too low and the humidity is too high, heating and dehumidifying equipment are activated simultaneously to raise the temperature and lower the humidity. S303: During the control process, the growth status of Fritillaria cirrhosa is observed in real time through video monitoring. Combined with real-time temperature and humidity data fed back by sensors, the operating power and running time of the control equipment are dynamically adjusted to optimize the control effect.
[0048] In the aforementioned process, high-definition video monitoring equipment is deployed in the Fritillaria cirrhosa cultivation greenhouse or shed, using a combination of even and focused deployment based on the greenhouse size and planting layout. This ensures full coverage of the planting area with no blind spots. Additional monitoring points are added at the greenhouse edges, ventilation openings, and around control equipment areas, with adjusted monitoring angles for close-range, precise monitoring. The video monitoring equipment uses high-definition infrared cameras that support all-weather operation. During the day, normal shooting mode is used to clearly capture details such as the condition and growth status of Fritillaria cirrhosa leaves; at night, infrared shooting mode is used to avoid monitoring blind spots caused by insufficient light, ensuring clear image data of the planting area can be obtained around the clock.
[0049] Simultaneously, temperature and humidity sensors are evenly distributed within the cultivation greenhouse, working in conjunction with the soil moisture sensor in step S201. The number and spacing of the temperature and humidity sensors are rationally set according to the greenhouse area to ensure that the collected data comprehensively reflects the air temperature and humidity conditions at different locations within the greenhouse. All sensors are high-precision digital sensors, with a temperature acquisition accuracy of ±0.1℃ and a humidity acquisition accuracy of ±1%RH, ensuring data accuracy. Data is collected synchronously at a preset frequency: one frame of image data is collected every 5 minutes, and temperature and humidity data are collected once per minute, achieving synchronous acquisition, transmission, and storage of image data and temperature and humidity data.
[0050] After receiving synchronously collected air temperature data, air humidity data, and planting area image data, the system first preprocesses all types of data to remove invalid temperature and humidity data caused by sensor malfunctions or signal interference, as well as invalid image data caused by blurry images or angle deviations, ensuring the validity of the analyzed data. Subsequently, the preprocessed temperature and humidity data are synchronously correlated with the image data: on the one hand, the real-time temperature and humidity data are compared with the preset core thresholds for the corresponding growth stage in step S100 to determine whether the temperature and humidity are within a suitable range; on the other hand, image recognition technology is used to analyze the growth status of Fritillaria cirrhosa in the images, focusing on the degree of leaf expansion, leaf color, and the presence of signs of wilting or mold, to help determine the rationality of temperature and humidity control.
[0051] For example, if the real-time temperature and humidity data are within the preset threshold range, but the image shows that the leaves of the Fritillaria cirrhosa are curled and yellow, it is determined that although the current temperature and humidity conditions are normal, they are still not suitable for plant growth and further fine-tuning is required. If the real-time temperature and humidity data are close to the threshold boundary, but the plant growth status in the image is good, the control operation can be temporarily suspended and monitoring can continue. When either the temperature or humidity data exceeds the preset threshold, a single parameter control method is not used. Instead, the correlation between the two is combined for coordinated control: if the temperature is too high and the humidity is too low, the environment is in a high-temperature and dry state. Cooling equipment (ventilation fans, shade nets, refrigeration units) and humidifying equipment (ultrasonic humidifiers, sprayers) are activated simultaneously. The cooling equipment quickly lowers the greenhouse temperature, and the humidifying equipment simultaneously increases the air humidity, achieving coordinated optimization of temperature and humidity. If the temperature is too low and the humidity is too high, the environment is in a low-temperature and high-humidity state. Heating equipment (heaters, insulation curtains) and dehumidifying equipment (dehumidifiers) are activated simultaneously. The heating equipment gradually increases the greenhouse temperature, and the dehumidifying equipment quickly lowers the air humidity, avoiding single control from causing the other parameter to become abnormal and ensuring that the temperature and humidity return to the appropriate range simultaneously.
[0052] After the coordinated temperature and humidity control is activated, it continuously links with video monitoring equipment and temperature and humidity sensors for dynamic monitoring and real-time adjustments to ensure that the control effect matches the actual growth of Fritillaria cirrhosa. On the one hand, the video monitoring equipment observes the changes in the growth status of Fritillaria cirrhosa in real time, capturing one frame of image every 3 minutes, focusing on monitoring changes in leaf condition and growth trend to determine whether the control operation has a positive impact on plant growth; on the other hand, the acquisition frequency of the temperature and humidity sensors is increased to once every 30 seconds to capture the changing trends of temperature and humidity data in real time, monitoring whether the temperature and humidity are gradually approaching the preset threshold range and whether the rate of change is reasonable.
[0053] Based on the plant growth status reported by video monitoring and the temperature and humidity changes reported by sensors, the operating power and duration of the control equipment are dynamically adjusted: If the temperature and humidity data gradually approach the suitable range, and the leaves of the Fritillaria cirrhosa in the image gradually unfold and return to normal color, it indicates that the control effect is good. The operating power of the control equipment is gradually reduced and the duration of operation is shortened to avoid over-control and secondary abnormalities in temperature and humidity; If the temperature and humidity data change slowly and the expected control effect is not achieved, and the plant growth status in the image does not improve, the operating power of the control equipment is appropriately increased and the duration of operation is extended to accelerate the return of temperature and humidity to the suitable range; If new growth abnormalities are found in the image during the control process (such as water droplets on the leaves or slight mold), the operating status of the control equipment is immediately fine-tuned even if the temperature and humidity data is being adjusted to prevent the abnormality from worsening.
[0054] Throughout the entire control process, the operating parameters of the control equipment, temperature and humidity change data, image data, and adjustment records are recorded simultaneously to form a complete control log. This provides data support for subsequent optimization of temperature and humidity thresholds and improvement of control strategies, continuously enhancing the accuracy of coordinated control and ensuring that the temperature and humidity environment always meets the growth needs of Fritillaria cirrhosa.
[0055] Corresponding to the aforementioned embodiments of the intelligent temperature and humidity control method for Fritillaria cirrhosa cultivation, this application also provides embodiments of an intelligent temperature and humidity control system for Fritillaria cirrhosa cultivation.

The dynamic control irrigation module 402 is used to collect soil moisture in real time, start and stop irrigation according to the moisture threshold, and monitor irrigation abnormalities.

When an abnormality occurs, it stabilizes the humidity by reducing the threshold difference. The temperature and humidity linkage control module 403 links video monitoring and sensor data to perform coordinated control of temperature and humidity.
