Description

A biomimetic adaptive structure-based pest and disease control device and method Technical Field

[0001] This invention relates to the field of pest and disease control technology, specifically to a pest and disease control device and method based on a biomimetic adaptive structure. Background Technology

[0002] Pest and disease control in agriculture is a crucial aspect of ensuring healthy crop growth, especially in greenhouses where the enclosed environment facilitates the rapid proliferation and spread of pests and diseases. Therefore, precise pest and disease control methods tailored to enclosed environments are particularly important. Currently, the use of ozone for pest and disease control is gaining increasing attention due to its strong oxidizing power, effectively killing bacteria and pests without leaving chemical residues. However, existing ozone-based pest and disease control equipment still has many shortcomings in practical applications, failing to fully meet the demands for precise, efficient, and safe pest and disease control.

[0003] In existing technologies, some simple ozone spraying devices lack precise matching with crop canopies, failing to adaptively adjust the ozone spraying height or method according to the actual crop height and canopy density, thus affecting the accuracy of ozone distribution and control effectiveness. Furthermore, existing devices typically lack ozone venting and moisture drying functions. After high-humidity operation, condensation often forms on the equipment surface, leading to corrosion and hindering long-term use. Additionally, the slow removal of residual ozone after operation may cause secondary pollution to crops and the environment.

[0004] Therefore, the device described in this paper has significant shortcomings in terms of overall structural stability, ozone concentration distribution control, synergistic regulation of humidity and ozone, residual ozone discharge, and subsequent equipment drying, making it difficult to achieve safe, accurate, and efficient pest and disease control. Summary of the Invention

[0018] An air heating device is also provided on the side of the main gas supply pipe near the branch gas supply pipe. The air heating device is used to heat the air output temperature of the main gas supply pipe.

[0019] Optionally or preferably, a motor is provided on the bone block unit, the motor is correspondingly arranged with the nozzle, and is used to control the output direction of the nozzle.

[0020] Optionally or preferably, the umbrella ribs are also covered with an umbrella surface, which is a flexible surface.

[0021] Optionally or preferably, a humidifier is also provided in the crop space, and the humidifier is electrically connected to the data acquisition and control module.

[0022] A method for pest and disease control based on adaptive umbrella rib structure includes the following steps:

[0023] S1. Deployment device: The umbrella ribs are slowly lowered through the lifting assembly until the umbrella rib support is in place;

[0024] S2. Humidity control: The humidity in the crop space is adjusted by a humidifier, and the humidity in the crop space is monitored by a temperature and humidity detection module.

[0028] S6. The device is retracted and dried. The umbrella ribs are slowly raised through the lifting component, and hot air flow heated by the air heating device is input into the crop space through the control air circuit component.

[0036] S32. If the ozone concentration in the lower layer of the crop space is less than the preset value, then determine that there is an ozone gap and calculate the location of the gap:

[0037] ;

[0038] ;

[0039] Among them, P low Let S be the coordinates of the gap center, n be the number of ozone concentration detection modules, and S be the coordinates of the gap center. i Let C be the spatial coordinates of the i-th ozone concentration detection module. i C represents the ozone concentration monitoring value. t This is the preset value for ozone concentration;

[0043] The coordinates of the gap center are: The coordinates of the nozzle are , where is the horizontal rotation angle of the nozzle, is the vertical rotation angle of the nozzle, and is the horizontal distance between the nozzle and the center of the notch;

[0044] If the ozone concentration in the upper layer of the crop space is less than the preset value, ozone compensation spraying will be carried out directly through adjacent nozzles.

[0045] S34. After 25 minutes of compensatory spraying, proceed to step S4.

[0046] Optionally or preferably, after compensating the lower layer of the crop space in S32, if the ozone concentration in the lower layer does not increase significantly but the ozone concentration in the upper layer does increase significantly, it is determined that the number of gaps is greater than 1, and the nozzle is controlled to rotate to a position 45° perpendicular to the ground for rotational spraying until the ozone concentration in the lower layer reaches the preset value.

[0049] In addition, the umbrella frame formed by hinged multiple bone blocks allows the size of the umbrella ribs to be adjusted according to the actual spraying area. Combined with the flexible umbrella surface, it can also reduce the vibration generated during ozone or high-pressure air spraying, thereby reducing the impact on the crop space greenhouse.

[0050] This invention provides a pest and disease control method based on an adaptive umbrella rib structure. On the one hand, it uses ozone gap judgment to monitor ozone concentration in real time and dynamically adjust the spraying angle to ensure that ozone evenly covers the crop canopy, significantly improving the efficiency of pest and disease control and avoiding the problem of excessively high or low local concentrations.

[0051] On the other hand, the airflow-induced dilution and thermal circulation drying system are designed in conjunction with each other. High-speed airflow accelerates the dilution and discharge of ozone, and hot air jets evaporate condensate and eliminate ozone residue, shortening the environmental recovery time and improving the safety and operating efficiency of the equipment.

Detailed Implementation

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] Please refer to Figures 1 to 4. A pest and disease control device based on a biomimetic adaptive structure is suspended on the greenhouse above the crop space 500 by a lifting component 300. It includes umbrella ribs 100, air passage components 200 and sensor components 400.

[0062] In this embodiment, the umbrella rib 100 includes a support column 110 and a plurality of umbrella rib supports 120 connected to the support column 110. The umbrella rib supports 120 are arranged in a cross pattern, and after the umbrella surface 600 is laid, a dome-shaped umbrella rib support structure is formed.

[0063] The umbrella rib support 120 includes multiple bone block units 130, and adjacent bone block units 130 are hinged together by hinges 140. It should be noted that the bone block unit 130 adjacent to the support column 110 is fixedly connected to the support column 110.

[0064] In actual work, due to different spraying areas, it is necessary to change the spraying structure with different spraying areas. In this embodiment, the spraying area can be adjusted by setting different numbers of bone block units 130 on the umbrella rib support 120.

[0065] In addition, in this embodiment, the umbrella rib 100 is a snake-like structure formed by hinged multiple rib block units 130, which can avoid the force and vibration generated by the air path assembly 200 when outputting airflow. At the same time, a flexible umbrella surface 600 is laid on the umbrella rib support 120, which is used to prevent the rapid dissipation of the injected gas.

[0066] In this embodiment, the lifting assembly 300 includes an electric telescopic rod, which is fixedly connected to the support column 110.

[0067] The aforementioned gas circuit assembly 200 includes a gas delivery module 240, a main gas delivery pipe 210, multiple gas delivery branch pipes 220, and nozzles 230; wherein, the output end of the gas delivery module 240 is connected to the input end of the main gas delivery pipe 210, the output end of the main gas delivery pipe 210 is connected to multiple gas delivery branch pipes 220, and multiple nozzles 230 are spaced apart on each gas delivery branch pipe 220.

[0068] The gas supply branch pipe 220 is correspondingly installed on the umbrella rib support 120 and fixed to the umbrella rib support 120; a motor 131 is installed on the rib unit 130, and the output shaft of the motor 131 is connected to a rotating structure. The rotating structure is fixed to the nozzle 230 and can twist the nozzle 230, thereby changing the output direction of the nozzle 230.

[0069] It should be noted that in this embodiment, the gas supply branch pipe 220 and the nozzle 230 are also flexible pipes.

[0070] Depending on the actual working needs, the gas supply assembly 200 needs to input different types of media into the crop space 500. In this embodiment, the media include ozone, room temperature air, high temperature air, and inert gas. Correspondingly, the gas supply module 240 includes an ozone source 241, an air source 242, and an inert gas source 243. An air heating device 250 is provided on the side of the main gas supply pipe 210 near the branch pipe 220. When high temperature air needs to be output, the air heating device 250 is turned on to heat the air passing through. The gas supply module 240 is connected to the input end of the main gas supply pipe 210 through a two-position valve.

[0071] The aforementioned sensor assembly 400 includes a ranging module 410 disposed at the end of the umbrella rib support 120, a temperature and humidity detection module 420 disposed in the crop space 500, and multiple ozone concentration detection modules 430.

[0072] The ranging module 410 is a laser rangefinder used to detect the distance between the end 120 of the umbrella rib support and the crop canopy.

[0073] Multiple ozone concentration detection modules 430 are arranged around the crop space 500 and are set on the upper and lower sides respectively to detect the concentration in the upper and lower layers of the crop space 500.

[0074] In this embodiment, the lifting assembly 300, the air supply module 240, and the sensor assembly 400 are all electrically connected to the data acquisition and control module, and the operator can monitor and control the above components through the data acquisition and control module.

[0075] In this embodiment, a humidifier is also provided in the crop space 500 in order to regulate the humidity. In other embodiments, the air supply module 240 also includes a humidifying air source for outputting air with a certain humidity, thereby regulating the humidity in the crop space 500.

[0076] Example 2

[0077] Please refer to Figure 5. Based on Embodiment 1, this embodiment provides a square-top umbrella rib structure with an umbrella rib arrangement. The difference from Embodiment 1 is that in this embodiment, multiple umbrella rib supports 120 are arranged in parallel and connected by support columns 110 to form a square-top umbrella rib structure in conjunction with the umbrella surface 600.

[0078] In actual operation, operators can choose the arrangement of the umbrella rib structure according to the actual work needs.

[0079] Specifically, for fruit trees, whose growth structure is relatively irregular, with high canopy density and asymmetrical distribution, a multi-dimensional spraying system with a dome-shaped rib structure is suitable. For crops such as wheat and corn, which can be planted in regular rows, the square-topped rib structure provides a more symmetrical spraying range due to their more uniform planting density and structure, ensuring that each row of crops is evenly covered.

[0080] In addition, this embodiment also provides a method for calculating the curvature of the umbrella rib support 120:

[0081]

[0082] Wherein, represents the curvature of the umbrella rib support 120 at position x. denoted as the maximum height of the crop, x as the distance from the central support point of the skeletal unit 130 along the horizontal axis, R as the lateral range of the crop canopy, H as the average height of the crop, and α as the bending strength coefficient.

[0083] Example 3

[0084] Please refer to Figure 6. This embodiment, based on Embodiment 1 and Embodiment 2, provides a pest and disease control method based on an adaptive umbrella rib structure, including the following steps:

[0085] S1. The deployment device slowly lowers the umbrella rib 100 through the lifting component 300 until the umbrella rib support 120 is in place.

[0086] Specifically, after the device is started, the umbrella rib 100 slowly descends under the control of the lifting component 300. At this time, the distance measuring module 410 at the end of the umbrella rib support 120 monitors the distance between the end of the umbrella rib support 120 and the crop canopy in real time and feeds the data back to the data acquisition and control module. When the value detected by the distance measuring module 410 reaches the threshold, the lifting component 300 controls the umbrella rib 100 to stop descending.

[0087] S2. Humidity control: The humidity within the crop space 500 is adjusted by a humidifier, and the humidity within the crop space 500 is monitored by a temperature and humidity detection module 420.

[0088] Specifically, after the device is positioned, the control system activates the humidifier, gradually increasing the humidity inside the enclosure according to feedback control logic. The humidity sensor collects data every 10 seconds, and the automatic humidity controller dynamically adjusts the humidity generator output based on a set threshold (70% ± 5%). When the humidity reaches the set range, the humidity generator automatically stops. This system, through precise humidity control, enhances the oxidation efficiency of ozone molecules, ensuring maximum effectiveness in pest and disease control.

[0089] In this embodiment, the method for adjusting the humidity within the crop space 500 using a humidifier includes the following steps:

[0090] S21. Adjust the output intensity of the humidifier and feed the collected data back to the data acquisition and control module through the temperature and humidity detection module 420:

[0091]

[0092] Where P is the output intensity of the humidifier, and H... t For the target humidity, H c The current humidity is given by K, which is a proportional control constant. In this embodiment, the target humidity is H. c The range can be 70% ± 5%, and the control ratio constant is 0.5.

[0093] S22. Determine the current humidity. When the humidifier stops operating.

[0094] S3, Ozone spraying and control: The ozone concentration in the crop space 500 is adjusted through the gas path component 200, and the ozone concentration in the crop space 500 is monitored through the ozone concentration detection module 430.

[0095] In this embodiment, the above-mentioned ozone spraying and control method includes the following steps:

[0096] S31. The ozone concentration detection module 430 simultaneously monitors the upper and lower ozone concentrations of the crop space 500 and feeds the collected data back to the data acquisition and control module.

[0097] Specifically, after humidity control is completed, all nozzles 230 simultaneously begin vertically releasing ozone to achieve rapid initial ozone distribution within the 500-square-meter greenhouse. To ensure uniform ozone concentration distribution, the system uses an array of ozone concentration detection modules 430 arranged within the crop space for real-time monitoring; each module measures ozone once per second, collecting ozone concentration data from different locations within the 500-square-meter crop space. When the concentration monitored in the upper layers exceeds the set target value, the system automatically stops the release from the upper-layer nozzles 230 and simultaneously switches to monitoring the concentration changes of the lower-layer sensors.

[0098] S32. If the ozone concentration in the lower 500 layer of the crop space is less than the preset value, then determine that there is an ozone gap and calculate the gap location:

[0099]

[0100]

[0101] Among them, P low Let S be the coordinates of the gap center, n be the number of ozone concentration detection modules, and S be the coordinates of the gap center. i Let C be the spatial coordinates of the i-th ozone concentration detection module. i C represents the ozone concentration monitoring value. t This is the preset value for ozone concentration;

[0102] In this embodiment, after compensating the lower layer of the crop space 500, if the ozone concentration in the lower layer does not increase significantly, but the ozone concentration in the upper layer does increase significantly, it is determined that the number of gaps is greater than 1, and the nozzle 230 is controlled to rotate to a position perpendicular to the ground at 45° for rotational spraying until the ozone concentration in the lower layer reaches the preset value.

[0103] S33. The nozzle 230 is rotated by motor 131 to face the center of the notch for ozone compensation spraying. The rotation angle of nozzle 230 is:

[0104]

[0105]

[0106] The coordinates of the gap center are: The coordinates of nozzle 230 are , where is the horizontal rotation angle of nozzle 230, is the vertical rotation angle of nozzle 230, and is the horizontal distance between nozzle 230 and the center of the notch;

[0107] If the ozone concentration in the upper layer of the crop space 500 is less than the preset value, ozone compensation spraying will be carried out directly through the adjacent nozzle 230.

[0108] S34. After 25 minutes of compensatory spraying, proceed to step S4.

[0109] S4, Inert gas spraying, inert gas is sprayed into the crop space 500 through the gas path component 200;

[0110] Specifically, inert gas is sprayed into the crop space 500 through inert gas source 243 to isolate the air and thus enhance the oxidizing capacity of ozone.

[0111] S5. Ozone and inert gas are discharged. High-speed airflow is introduced into the crop space 500 through the control air path component 200 to reduce the concentration of ozone and inert gas in the crop space 500. The ozone concentration in the crop space 500 is monitored by the ozone concentration detection module 430.

[0112] Specifically, after spraying ozone into the crop space 500 and completing pest and disease control, the system switches to ozone exhaust mode, switches the gas supply module 240 to air source 241, and starts the nozzle 230 to release high-speed air to dilute the residual ozone in the crop space 500. During the dilution process, the ozone concentration in the crop space 500 is monitored in real time by detection modules distributed at different positions above and below. These sensors collect concentration data at a frequency of 1 Hz and upload it to the feedback data acquisition and control module.

[0113] The goal of the venting is to reduce the ozone concentration within the crop space to a safe threshold (below 0.05 ppm) to ensure the safety and sustainable operation of the greenhouse environment; by disturbing the gas distribution inside the enclosure with high-speed airflow, the high-concentration ozone area is rapidly diffused and mixed with fresh air.

[0114] S6. The device is retracted and dried. The umbrella rib 100 is slowly raised by the lifting component 300, and the hot air flow heated by the air heating device 250 is input into the crop space 500 by the control air circuit component 200. The temperature and humidity in the crop space 500 are monitored by the temperature and humidity detection module.

[0115] After the dilution stage is completed, the system switches to the hot air drying mode. While the umbrella rib 100 is raised by the lifting component 300, the air supply module 240 is controlled to become the air source 242 and the air heating device 250 is turned on to reduce the humidity of the umbrella surface 600 and ensure the safe operation of the equipment. The drying temperature adjustment range is 50℃-70℃.

[0116] Specifically, the umbrella ribs 100 slowly rise, suspending the umbrella surface 600 in the air and creating optimal coverage conditions for hot air injection. Subsequently, the nozzles switch to hot air mode, and motor 131 adjusts the nozzles 230 to a preset angle, ensuring that hot air evenly covers the umbrella surface 600. The injected hot air rapidly evaporates condensate by heating the umbrella surface 600 and the crop space 500, reducing humidity and preventing residual moisture from corroding critical components such as the umbrella ribs 100 and nozzles 230. Furthermore, the high temperature of the hot air further decomposes any remaining ozone molecules, enhancing the safety and stability of the internal environment.

[0117] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The pest and disease control method based on adaptive umbrella rib structure according to claim 3, characterized in that, Methods for ozone spraying and regulation in S3 The process includes the following steps: S31, simultaneously monitoring the upper and lower ozone concentrations of the crop space (500) using the ozone concentration detection module (430), and feeding the collected data back to the data acquisition control module; S32, if the lower ozone concentration of the crop space (500) is less than a preset value, then determining that there is an ozone gap and calculating the gap location: Among them, P low Let S be the coordinates of the gap center, n be the number of ozone concentration detection modules, and S be the coordinates of the gap center. i Let C be the spatial coordinates of the i-th ozone concentration detection module. i C represents the ozone concentration monitoring value. t Set the ozone concentration to the preset value; S33, rotate the nozzle (230) to face the center of the gap via the motor (131) to perform ozone compensation spraying. The rotation angle of the nozzle (230) is: The coordinates of the gap center are: The coordinates of nozzle (230) are , is the horizontal rotation angle of the nozzle (230), is the vertical rotation angle of the nozzle (230), and is the horizontal distance between the nozzle (230) and the center of the notch; if the ozone concentration in the upper layer of the crop space (500) is less than the preset value, ozone compensation spraying is carried out directly through the adjacent nozzle (230); S34, after 25 minutes of compensation spraying, proceed to step S4.

6. The pest and disease control method based on an adaptive umbrella rib structure according to claim 5, characterized in that, If the ozone concentration in the lower layer of the crop space (500) does not increase significantly after the compensation spraying in S32, but the ozone concentration in the upper layer increases significantly, it is determined that the number of gaps is greater than 1, and the nozzle (230) is controlled to rotate to a position 45° perpendicular to the ground for rotational spraying until the ozone concentration in the lower layer reaches the preset value.
