While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
Referring to fig. 1, this embodiment provides a high-yield cultivation system for fruit tomatoes, comprising: the fruit tomato plant growth device comprises an acquisition unit and a judging unit, wherein the acquisition unit is configured to acquire image data of the fruit tomato plant, acquire height data of the fruit tomato plant according to the image data, analyze the height data and judge whether the growth environment of the fruit tomato plant needs to be regulated. The judging unit is configured to obtain soil humidity data S0 and preset a lowest humidity threshold value Smin and a highest humidity threshold value Smax when the collecting unit judges that the growing environment of the fruit tomato plant needs to be regulated, and judge whether to regulate the soil humidity according to the size relation between the soil humidity data S0 and the lowest humidity threshold value Smin and the highest humidity threshold value Smax.
When S0 < Smin, the judging unit judges that the soil humidity is subjected to humidification regulation. When the judging unit judges that the soil humidity is humidified and adjusted, the indoor air humidity data Sk is also acquired, and whether the air supply device is started or not is judged according to the indoor air humidity data Sk. When the judging unit judges that the air supply device needs to be started, the initial power of the air supply device is determined according to the indoor air humidity data Sk and the outdoor air humidity data Sw.
When Smin is less than or equal to S0 and less than or equal to Smax, the judging unit judges that the soil humidity is not regulated. When the judging unit judges that the soil humidity is not regulated, the fertilizer applying device is further configured to acquire the soil nutrient content Y0, and the working frequency of the fertilizer applying device is regulated according to the relation between the soil nutrient content Y0 and the preset nutrient content.
When S0 > Smax, the judging unit judges that the soil humidity is subjected to dehumidification regulation and starts the drainage device. When the judging unit judges that the soil humidity is subjected to dehumidification regulation, the soil air permeability is obtained, and the valve opening of the drainage device is set according to the soil air permeability.
In particular, photographic or video-taking devices, such as cameras or video cameras, are installed to take pictures or record fruit tomato plants at clear angles and distances of the taken pictures. These devices may be installed in a plant growing area to capture image data of plants. The acquired image data is transmitted to a computer or embedded system for processing. By wired or wireless connection. After transmission, the image data is stored for subsequent analysis. Highly relevant features are extracted from plant contours. Vertical lines or contours from the bottom of the plant to the top of the plant may be selected to represent plant height. In order to convert the extracted features to actual height values, scaling is required. By placing a calibration object of known height in the actual scene. Using the calibration data and the extracted features, the system can calculate the height of the plant in the image. Through the analysis of the height data, the growth state of the current fruit tomato plant can be judged, and whether the growth environment needs to be adjusted or not is further determined. The judging unit takes corresponding measures under different conditions according to the judging result of the collecting unit. When it is determined that the plant growth environment needs to be regulated, the determining unit may acquire soil humidity data S0, and preset threshold ranges Smin and Smax of humidity. Comparing the soil moisture data to a preset threshold, the system may determine whether to adjust the soil moisture. If the soil humidity is too low, the system starts humidification regulation to provide proper water supply, and meanwhile judges whether an air supply device needs to be started according to indoor humidity data Sk to keep proper environmental humidity. When the air supply is judged to be needed, the initial power of the air supply device is determined according to the indoor humidity and the outdoor humidity data. If the soil humidity is within a suitable range, the system remains in a steady state without humidity regulation. At the moment, the judging unit can detect the soil nutrient content Y0, and adjust the working frequency of the fertilizer device according to the preset nutrient content so as to ensure the nutrient supply of plants. When the soil humidity is too high, the judging unit can start the dehumidification adjustment and start the drainage device. Meanwhile, the system can set the valve opening of the drainage device according to the soil air permeability, so that proper drainage of the soil is ensured.
It can be understood that by the intelligent regulation means, the system realizes the fine management of the growth environment of the fruit tomatoes, is flexibly regulated according to actual conditions, improves the growth efficiency and yield of plants, and reduces the resource waste.

And judging whether to regulate the growing environment of the fruit tomato plant according to the comparison relation of the height data H0, the highest height threshold Hmax and the lowest height threshold Hmin. When H0 is less than Hmin, the acquisition unit judges that the growth environment of the fruit tomato plants is regulated. When Hmin is less than or equal to H0 and less than or equal to Hmax, the acquisition unit judges that the growth environment of the fruit tomato plant is not regulated.
It will be appreciated that the height data H0 represents plant height data acquired by the acquisition unit. The height minimum threshold Hmin represents a predetermined minimum height of plant growth. The highest height threshold Hmax represents a preset highest height of plant growth. When the plant height H0 is less than the minimum threshold Hmin, the system determines that an environment needs to be regulated to promote plant growth. When the plant height is between the lowest threshold and the highest threshold, the plant is considered to be in a proper growth state without regulation. Through real-time monitoring and analysis of the plant height of the fruit tomatoes and combination of threshold setting, fine adjustment of the plant growth environment is achieved. The system can automatically judge the growth state of the plant, and correspondingly adjust the plant according to the needs, thereby ensuring that the plant thrives in a proper growth environment. This not only contributes to an improvement in yield and quality, but also reduces waste of resources.
In some embodiments of the present application, when the judging unit judges that humidification adjustment is performed on the soil humidity, the indoor air humidity data Sk is also acquired, and whether to turn on the air blowing device is judged according to the indoor air humidity data Sk, including: the judging unit is further configured to preset the standard indoor air humidity Sk0, and determine whether to turn on the air supply device according to the magnitude relation between the indoor air humidity data Sk and the standard indoor air humidity Sk 0. When Sk is more than or equal to 0.9Sk0 and less than or equal to 1.1Sk0, the judging unit judges that the air supply device is not required to be started, and the irrigation device is started to humidify and regulate the soil humidity. When Sk is less than 0.9Sk0, the judging unit judges that the air supply device is required to be started, and the irrigation device is started to humidify and regulate the soil humidity.
It will be appreciated that the indoor air humidity data Sk is acquired using a humidity sensor. The standard indoor air humidity Sk0 is preset, and the standard indoor air humidity Sk is compared with the actually measured indoor humidity data to judge whether the air supply device needs to be started or not. And triggering the corresponding air supply and irrigation device to control according to the comparison result of the indoor humidity data and the standard humidity. When Sk is more than or equal to 0.9Sk0 and less than or equal to 1.1Sk0, the humidity in the air is proper, and the irrigation device is only required to be started to enhance the soil humidity without humidifying the air. When Sk < 0.9Sk0, the lower humidity in the air is indicated to enhance the soil humidity and the water content in the air. The irrigation device and the air supply device are used for improving humidity and are controlled by the judging unit.
It can be understood that a more refined and comprehensive environment regulation mode is provided, and the growth environment of the fruit tomato plants is effectively optimized by automatically selecting a proper control strategy through monitoring and analyzing the indoor humidity in real time. The intelligent regulation and control of the system not only is beneficial to maintaining the humidity level required by the plant, but also can reduce the influence of excessive humidification or drying on the plant health, and improves the growth quality and yield of the plant. Meanwhile, the system controls the air supply device and simultaneously opens the irrigation device, so that the dual regulation of soil humidity and indoor humidity is realized, and the synergistic effect is more remarkable.
In some embodiments of the present application, when the judging unit judges that the air supply device needs to be turned on, determining the initial power of the air supply device according to the indoor air humidity data Sk and the outdoor air humidity data Sw includes: the judging unit is also configured to acquire a humidity difference Δs=sw-Sk between the outdoor air humidity data Sw and the indoor humidity data Sk.

When Qw is more than or equal to 0.95 and less than or equal to 1.05Qw, the judging unit judges that the heat exchange device is not started. When Qk is less than 0.95Qw or Qk is more than 1.05Qw, the judging unit judges that the heat exchange device is started.
Specifically, when the air supply device is turned on, if the temperature difference between the outdoor and indoor is large, the fluctuation of the temperature in a large range is caused when the outside air is supplemented into the indoor, and the plant growth is affected, so that the heat exchange device is turned on to maintain the indoor temperature environment.
It will be appreciated that by comprehensively considering the difference between the indoor temperature and the outdoor temperature, it is intelligently decided whether to turn on the heat exchange device. The system realizes the automatic control of the heat exchange device according to the comparison result of the temperature data. When the difference between the indoor temperature and the outdoor temperature is large, the indoor environment can be adjusted by starting the heat exchange device, the stable temperature level is maintained, the proper growth environment is provided, and healthy growth of plants is promoted.
In some embodiments of the present application, when the judging unit judges that the heat exchanging device is turned on, the judging unit is further configured to obtain a temperature difference Δq=qk-Qw between the indoor temperature data Qk and the outdoor temperature data Qw. The first preset difference DeltaQ 1 and the second preset difference DeltaQ 2 are preset, and DeltaQ 1 is less than 0 < DeltaQ2.

When DeltaQ is less than or equal to DeltaQ 1, the judging unit starts the heating mode of the heat exchange device and determines the operation power of the heat exchange device as R2. When DeltaQ 1 < DeltaQis less than or equal to 0, the judging unit starts the heating mode of the heat exchange device and determines the running power of the heat exchange device as R1. When DeltaQ is less than or equal to 0 and less than DeltaQ 2, the judging unit starts the refrigeration mode of the heat exchange device and determines the operation power of the heat exchange device as R1. When DeltaQ 2 is less than or equal to DeltaQ, the judging unit starts the refrigeration mode of the heat exchange device and determines the operation power of the heat exchange device as R2.
It is understood that the heat exchange device functions with the air entering the room through the air inlet device, and the heat exchange device is also controlled by the judging device. By taking into account the difference between the indoor and outdoor temperatures, the operating mode and power of the heat exchange device is intelligently adjusted to achieve more accurate temperature regulation. By reasonably distributing the heating and refrigerating modes, the growth environment of the fruit tomatoes can be effectively stabilized, proper temperature conditions are provided, and healthy growth of plants is promoted.

When Y3 is less than or equal to Y0, the judging unit selects a first preset adjusting coefficient A1 to adjust the initial working frequency Lv0 of the fertilizer device, the adjusted working frequency Lv0 is obtained, and the judging unit controls the fertilizer device to continue to operate at the adjusted working frequency.
Specifically, the nutrient content refers to the concentration sum of various nutrient elements in the soil, including main nutrients required by plants such as nitrogen, phosphorus, potassium, and trace elements such as iron, zinc, copper, and the like. The nutrient content can be obtained by detection by using a soil nutrient sensor, and the soil nutrient sensor is a technology for monitoring the nutrient content in real time. These sensors may be installed in the soil to assess nutrient content by measuring the conductivity or other physical characteristics of the nutrients in the soil. The preset nutrient content is a target nutrient concentration determined within a preset reasonable nutrient range according to the growth requirement and soil property of a specific plant. This preset value may be regarded as a target or standard. The operating frequency of the fertilizer applicator refers to the number or frequency of the fertilizer application operations performed by the fertilizer applicator over a period of time.
It can be understood that the proper adjustment coefficient is intelligently selected according to the real-time condition of the nutrient content of the soil, so that the working frequency of the fertilizer device is accurately regulated and controlled. Through real-time monitoring and adjustment, the fruit tomatoes can be ensured to obtain proper nutrient supply, and the growth quality and yield of plants are improved.
In some embodiments of the present application, when the judging unit judges that the moisture removal adjustment is performed on the soil moisture, the soil air permeability is obtained, and the valve opening of the drainage device is set according to the soil air permeability, including:
The judging unit is also used for presetting a first preset soil air permeability T1, a second preset soil air permeability T2 and a third preset soil air permeability T3, wherein T1 is more than T2 and less than T3. The first preset valve opening K1, the second preset valve opening K2 and the third preset valve opening K3 are preset, and K1 is more than K2 and less than K3.
Specifically, the judging unit is further used for determining the valve opening of the drainage device according to the magnitude relation between the soil air permeability T0 and each preset soil air permeability. When T1 is less than or equal to T0 and less than T2, the judging unit determines that the valve opening of the water draining device is K3. When T2 is less than or equal to T0 and less than T3, the judging unit determines that the valve opening of the water draining device is K2. When T3 is less than or equal to T0, the judging unit determines that the valve opening of the water draining device is K1.
In some embodiments of the present application, after determining that the valve opening of the drainage device is Ki, i=1, 2,3, the determining unit is further configured to obtain a soil ph value J0, correct the valve opening Ki according to the soil ph value J0, and include: the judging unit is also used for presetting a first preset pH value J1, a second preset pH value J2 and a third preset pH value J3, wherein J1 is less than J2 and less than J3. The first preset correction coefficient B1, the second preset correction coefficient B2 and the third preset correction coefficient B3 are preset, and B1 is more than B2 and less than B3. When J1 is less than or equal to J0 and less than J2, a first preset correction coefficient B1 is selected to correct the valve opening Ki, and corrected valve opening Ki is obtained. When J2 is less than or equal to J0 and less than J3, selecting a second preset correction coefficient B2 to correct the valve opening Ki, and obtaining corrected valve opening Ki. When J3 is less than or equal to J0, a third preset correction coefficient B3 is selected to correct the valve opening Ki, and corrected valve opening Ki is obtained.
Specifically, soil air permeability at different levels and corresponding valve opening degrees are preset. The judging unit can determine the proper valve opening of the drainage device by comparing the relation between the actual soil air permeability and the preset value. Good soil permeability can promote oxygen in the soil to enter the root zone, and also helps to discharge excessive carbon dioxide. This is critical to both respiration and photosynthesis of the plant. If the soil is less breathable, the insufficient oxygen supply can affect respiration and energy metabolism of the root system, thereby affecting plant growth and development. Good soil air permeability is helpful for drainage, prevents soil from being excessively wet, and reduces the risks of root choking and root rot.
It will be appreciated that adjusting the valve opening of the drain can help maintain proper soil moisture for different soil permeabilities. When the soil air permeability is good, the valve opening of the drainage device can be properly reduced, and excessive water can be placed for drainage; when the soil air permeability is poor, the valve opening of the drainage device can be moderately increased, and the excessive moisture can be timely discharged. The change of the pH value can change the distribution and movement mode of the gas in the soil, thereby affecting the processes of root respiration, microbial activity and the like closely related to plant growth. The ph of the soil can affect the solubility of the gas in the soil and thus the mobility of the gas in the soil. When the soil is more acidic, the dissolved oxygen in the moisture increases, which promotes the flow of oxygen in the soil. Therefore, when the pH value is lower, the valve opening is properly reduced, and the oxygen is ensured to fully flow in the soil.
It can be understood that the influence of factors such as soil air permeability and pH value on the drainage device is comprehensively considered, more accurate drainage adjustment is realized, and the proper humidity and acid-base balance of the soil are maintained, so that the healthy growth and yield of the fruit tomato plants are improved.
In the embodiment, the image data of the fruit tomato plants are collected, and the height data of the plants are obtained through analysis, so that the growth stage of the plants is judged, and a basis is provided for subsequent growth environment adjustment. When the growth environment of the fruit tomato plants is judged to be required to be regulated, whether humidification or dehumidification regulation is required to be carried out is intelligently judged by utilizing the soil humidity data S0 and preset humidity thresholds Smin and Smax so as to maintain the soil humidity in a proper range. When the soil humidity is low, the system starts humidification regulation to ensure that the water supply of plants is sufficient. Meanwhile, the system can also determine whether to start the air supply device according to the change of the indoor air humidity data Sk so as to provide a proper growth environment. When the soil humidity is in the proper range, the system will remain stable without humidity adjustment to avoid over-wetting or over-drying. The system also adjusts the working frequency of the fertilizer device according to the comparison result of the soil nutrient content Y0 and the preset nutrient content, and ensures reasonable balance of plant nutrient supply. When the soil humidity is too high, the system starts the dehumidification regulation and starts the drainage device, so that the growth of plants is prevented from being influenced by moisture accumulation. Through obtaining the soil gas permeability, the valve aperture of drainage device is set for to intelligence, maintains the soil gas permeability, further promotes the healthy growth of fruit tomato plant.
