Description

Technical Field

[0001] This invention relates to the field of information automation technology, specifically to a smart tea garden management method and system. Background Technology

[0002] Traditional tea garden management has long relied heavily on manual experience for inspections and decision-making, which has inherent drawbacks such as low efficiency, slow response, and strong subjectivity in judgment. This can easily lead to the overuse of water resources and pesticides, which not only increases production costs but also poses a potential threat to the ecological environment.

[0003] Currently, Chinese patent application number CN202311399737.0 discloses a smart tea garden management method and system, including real-time collection of monitoring data from the tea garden; storage of each collected monitoring data; processing and analysis of the monitoring data to obtain the data change curve corresponding to each type of monitoring data; determining whether any monitoring data is higher or lower than a corresponding set threshold based on all the monitoring data; and controlling the corresponding actuator to work when it is higher or lower than the set threshold. By intelligently managing the tea garden and monitoring various data in real time, labor costs are reduced, and the data results are more objective, timely, and accurate through information-based data collection. The processing and analysis of the collected data to generate corresponding change curves can help users observe the current ecological condition of the tea garden online in a timely manner, and thus take timely countermeasures.

[0004] However, the data analysis methods of existing smart tea garden management technologies are relatively simple, mainly relying on comparisons with fixed thresholds. They lack the ability to perform deep learning and intelligent prediction of complex situations such as early visual characteristics of pests and diseases, resulting in limited decision-making accuracy. Furthermore, their execution mechanisms are usually fixed or have single functions, making it difficult for them to move autonomously in complex tea garden terrain and perform multi-functional operations such as precise variable-rate pesticide application, adaptive canopy height detection, and automated sampling. The system has poor flexibility and integration. Summary of the Invention

[0023] A data transmission module is used to transmit the environmental data to a data processing unit;

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention integrates environmental data collection, intelligent analysis, decision generation, and precise execution into a unified system, and achieves full-process automation from perception to action through a tea garden monitoring robot as its physical core. The robot integrates movement, detection, pesticide application, and sampling functions, enabling autonomous navigation and the execution of complex tasks. This significantly reduces reliance on manual labor, overcomes the inefficiencies and slow responses of traditional management methods, and achieves highly integrated and automated tea garden management, greatly improving operational efficiency.

[0029] This invention analyzes multi-source data using an artificial intelligence model, making pest and disease identification and water and fertilizer demand assessment more accurate. Based on this, the system can generate and execute precise management instructions. In particular, the robot's spraying structure can dynamically adjust the spray width and dosage, achieving "on-demand application" and avoiding excessive use and waste of pesticides.

[0030] The tea garden monitoring robot of this invention adopts an omnidirectional wheeled mobile platform, which can achieve flexible movement in all directions between narrow and uneven tea tree rows, including lateral translation and turning in place. This solves the problems of poor passability and large turning radius of traditional wheeled or tracked equipment in dense plantations. Furthermore, its support and moisture detection structure adopts a linkage amplification mechanism, which can convert the small vertical motion of the moisture detection screw into a large lifting of the top working platform. This allows the robot to flexibly adjust its "working field of view" and "working height" while stationary, adapting to the detection and operation needs of different canopy heights from seedlings to mature tea trees. This solves the industry pain points of limited field of view and fixed working range of fixed equipment, demonstrating a high degree of intelligence and flexibility. Attached Figure Description

Detailed Implementation

[0041] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0042] Please see Figures 1 to 9 This invention provides a smart tea garden management method, comprising the following steps:

[0043] Step S1: Collect environmental data by using multiple sensors deployed in the tea garden (such as fixed soil moisture sensors and weather stations) and mobile tea garden monitoring robots. The environmental data includes soil moisture, temperature, light intensity, and image data.

[0044] Step S2: Transmit the environmental data to the data processing unit via wired or wireless communication (such as LoRa or 5G). The data processing unit may be a local server or a cloud platform.

[0045] Step S3: Analyze the environmental data using an artificial intelligence model to identify the growth status and potential risks of the tea trees, including pests and diseases, water shortage or nutrient deficiency.

[0046] The step of using an artificial intelligence model for analysis specifically includes: processing the image data using a convolutional neural network (CNN) to accurately identify early symptoms of pests and diseases; integrating future weather forecast data and historical growth data of the tea garden; and optimizing the generation of management instructions through a predictive model (such as a time series prediction algorithm), for example, predicting water demand or the risk of pest and disease outbreaks in the next few days.

[0047] Step S4: Based on the analysis results, generate management instructions, including irrigation instructions, fertilization instructions, or pest and disease control instructions;

[0048] The step of generating management instructions is based on real-time data analysis and edge computing. Specifically, edge nodes are set up in the data processing unit to perform local data processing to reduce latency and achieve rapid response.

[0049] Step S5: Send the management instruction to the execution device to control the execution device to perform the corresponding operation, wherein the execution device includes a tea garden monitoring robot.

[0050] The method further includes controlling the tea garden monitoring robot to automatically navigate to a designated location according to the management instructions, and to perform mobile data collection (such as taking supplementary photos) and operation execution (such as applying pesticides and taking samples).

[0051] The method further includes controlling the tea garden monitoring robot to perform precise pesticide application operations based on the analysis results to dynamically adjust the amount and location of pesticide application, thereby avoiding waste and pollution; at the same time, the management instructions and data of the executed operations are recorded through blockchain technology to form an immutable production log, so as to realize the traceability of the entire tea supply chain from tea garden to teacup.

[0052] Please see Figure 2 The tea garden monitoring robot includes a mobile platform 1, which is equipped with a battery module to power the entire robot. Each of the four ends of the mobile platform 1 is connected to an omnidirectional wheel 2, which is driven and controlled by an independent servo motor, giving the robot all-around mobility. It can move straight, lateral, diagonally, and rotate in place in narrow tea tree rows, making it highly maneuverable.

[0053] The top of the mobile platform 1 is fixedly connected to a medicine tank 3 for storing the medicine solution, and a bumper 4 is installed on one side of the medicine tank 3 for cushioning and protection. A support moisture detection structure 5 is embedded through the middle of the medicine tank 3, and a columnar through groove is longitudinally opened in the middle of the mobile platform 1. The support moisture detection structure 5 passes through the columnar through groove, and a horizontal plate 6 is locked and fixed to the top of the support moisture detection structure 5. After the support moisture detection structure 5 is started, the height of the horizontal plate 6 is adjusted by raising and lowering, and the soil moisture can be detected when it is lowered to the bottom. Cameras 7 are installed on all four sides of the bottom of the horizontal plate 6 for collecting image data of the tea tree canopy from multiple angles. A spraying structure 8 is locked and fixed to the top right of the horizontal plate 6 to perform precise spraying operations, and a sampling structure 9 is installed on the top left of the horizontal plate 6 to pick and sample tea leaves. A liquid suction pump is installed inside the medicine tank 3, and the liquid outlet of the liquid suction pump is connected to the spraying structure 8 through a hose. The liquid suction pump provides spraying power and delivers the medicine solution to the spraying structure 8 for spraying the tea trees.

[0054] Please see Figure 3 and Figure 4 The support structure 5 includes a support frame 51 embedded and fixed inside the medicine compartment 3. A first motor 52 is locked and fixed inside the upper right side of the support frame 51. A first bevel gear 53 is connected to the output end of the left side of the first motor 52. A second bevel gear 54 is meshed and driven on the upper left side of the first bevel gear 53. An internal threaded cylinder 55 is fixed through the middle side of the second bevel gear 54. The internal threaded cylinder 55 rotates through the middle side of the top of the support frame 51. The first motor 52 is used as a power source to drive the first bevel gear 53, thereby driving the internal threaded cylinder 55 fixed to the second bevel gear 54 to rotate inside the support frame 51.

[0055] The screw 56 is threadedly connected to the internal threaded cylinder 55. The screw 56 moves linearly under the rotation drive of the internal threaded cylinder 55. A soil insertion assembly 57 is installed at the bottom of the screw 56. The screw 56 slides through the lower middle side of the support frame 51. The soil insertion assembly 57 slides through the middle bottom side of the support frame 51. A humidity sensor 58 is installed inside the soil insertion assembly 57. When the screw 56 moves vertically, it drives the soil insertion assembly 57 to be vertically inserted into the soil. The humidity sensor 58 extends through the further downward movement of the soil insertion assembly 57 to measure the humidity data in the soil.

[0056] The top end of the screw 56 is connected to the push plate 59, so that the linear motion is also transmitted to the push plate 59 synchronously. X-folding frames 510 are rotatably installed on the four sides of the push plate 59. The bottom ends of the four X-folding frames 510 are rotatably connected to the lower support rods 511, and the top ends of the upper support rods 512 are rotatably connected to the upper support rods 512. The other end of the lower support rods 511 is rotatably connected to the support frame 51, and the other end of the upper support rods 512 is rotatably connected to the pad 513. The top of the pad 513 is fastened to the horizontal plate 6. Through the cooperation of the X-folding frames 510, the upper support rods 512, and the lower support rods 511, the small displacement of the push plate 59 is amplified into a large platform lift. Thus, when the push plate 59 rises, it pushes the X-folding frames 510 around it to unfold. The upper support rods 512 lift the pad 513 and the horizontal plate 6 as a whole upward, so that the robot can significantly raise the height of its upper sensors and working mechanism without moving, in order to adapt to the tea tree canopy layer of different heights.

[0057] The soil insertion assembly 57 includes an outer cylinder 571 connected to a screw 56 at its top, so that when the screw 56 moves downward, the outer cylinder 571 moves downward synchronously and is inserted into the soil. The outer cylinder 571 is hollow inside, and a middle cylinder 572 is embedded and fixed in the lower middle side. A motor 573 is locked and fixed at the top of the middle cylinder 572. A threaded rod 574 is connected to the bottom output end of the motor 573. The threaded rod 574 passes through and is threadedly connected to the top middle side of the inner cylinder 575. The bottoms of the middle cylinder 572 and the inner cylinder 575 are both conical. The inner cylinder 575 is longitudinally slidably connected to the inside of the middle cylinder 572. The motor 573 is used as a power source to drive the threaded rod 574 to rotate, which in turn drives the inner cylinder 575 to move further downward from inside the middle cylinder 572.

[0058] A partition plate 576 is embedded and fixed inside the inner cylinder 575. A humidity sensor 58 is installed in the space formed by the partition plate 576 and the inner cylinder 575. The detection head of the humidity sensor 58 is embedded in the side wall of the inner cylinder 575. After the inner cylinder 575 moves down, the humidity sensor 58 is exposed to detect the soil humidity. During the process of inserting the whole into the soil, the humidity sensor 58 is protected inside the middle cylinder 572 to avoid excessive contact between the detection point of the humidity sensor 58 and the soil, which may cause friction and scratches. When it is moved to the position to be detected, the inner cylinder 575 and the humidity sensor 58 are lowered down to be exposed for detection.

[0059] Please see Figure 5 and Figure 6The spraying structure 8 includes a support 81 that is fastened to the horizontal plate 6 at the bottom center. The support 81 has two second motors 82 locked and fixed on the left and right sides of the center. The output ends of the two second motors 82 are connected to gear sets 83. The output of the gear sets 83 is connected to lead screws 84. The lead screws 84 are rotatably connected to the support 81 on both the front and rear sides, and the extended axes of the two lead screws 84 intersect. The outer surface of the lead screws 84 is threaded with internal thread sliders 85. The two second motors 82 are used as power sources. The two gear sets 83 drive the two lead screws 84 to rotate, so that the internal thread sliders 85 on the lead screws 84 move accordingly.

[0060] Two internal threaded sliders 85 are rotatably connected to universal joints 86 on opposite sides. The other end of the universal joint 86 is connected to a support plate 87. A slot is formed on the upper rear side of the support plate 87, with the front of the slot inclined. A V-shaped piece 88 is fixedly connected to this inclined section. The other side of the V-shaped piece 88 is inserted into and rotates inside a slot frame 89. Two slot frames 89 are fixedly connected to the rear of the left and right sides of the support 81, respectively. By controlling the two internal threaded sliders 85 to move forward or backward synchronously, the universal joint 86 drives the support plate 81. The V-shaped plate 88 forms a specific trajectory under the movement constraint of the slot frame 89, causing the two support plates 87 to move to the rear side below the support 81 and unfold in a straight line. Each of the two support plates 87 is equipped with a nozzle 810 on the side away from each other. The bottom of the nozzle 810 is connected to the liquid suction pump in the medicine tank 3 through a hose, so that the two nozzles 810 can open and close accordingly through the support plates 87, thereby adjusting the spraying range. It can achieve spraying of medicine by spraying medicine upward and spreading it out to the rear, so as to accurately apply medicine to specific tea trees.

[0061] Please see Figure 7 , Figure 8 and Figure 9 The sampling structure 9 includes a base 91 that is fastened to the bottom of the horizontal plate 6. A guide rod 92 is fixedly connected to the right side inside the base 91. A third motor 93 and a fourth motor 94 are locked and fixed to the middle front side and the left side of the base 91, respectively. A spiral rod 95 is connected to the rear output end of the third motor 93. An inner spiral sleeve 96 is threadedly connected to the outer surface of the spiral rod 95. The inner spiral sleeve 96 is installed through the middle inside the support 97. The right side inside the support 97 slides around the outer surface of the guide rod 92. The spiral rod 95 is driven to rotate by the third motor 93, which drives the inner spiral sleeve 96 and the entire support 97 to move back and forth along the guide rod 92, thereby realizing the horizontal feeding of the sampling component.

[0062] The fourth motor 94 has a sliding key rod 98 connected to its rear output end. The sliding key rod 98 is rotatably connected to the left side of the inside of the carrier 91. A worm sleeve 99 is wrapped around the outer surface of the sliding key rod 98. The worm sleeve 99 is rotatably connected to the lower left side of the inside of the carrier 97. The top of the worm sleeve 99 meshes with the worm wheel 910. An L-shaped rod 911 is fixedly connected inside the worm wheel 910. The L-shaped rod 911 passes through and rotates on the upper left side of the carrier 97. The top of the L-shaped rod 911 is fastened to the shearing assembly 912. The fourth motor 94 drives the sliding key rod 98, which drives the worm sleeve 99 to rotate. The worm sleeve 99 meshes with the worm wheel 910, driving the L-shaped rod 911 and the shearing assembly 912 at its top to rotate in the vertical plane, thereby adjusting the shearing angle. It also has a self-locking function to prevent the shearing assembly from shifting during operation, ultimately aligning the shearing assembly with the tea leaves to be picked.

[0063] The shearing assembly 912 includes a counterweight rod 9121 that is fastened to the bottom of an L-shaped rod 911 to balance the weight of the rear mechanism and maintain overall stability. A column rod 9122 is fixedly connected to the rear of the counterweight rod 9121. A leaf collection chamber 9123 for receiving and accommodating the cut tea samples is fixed to the rear of the column rod 9122. A blade holder 9124 is locked and fixed to the upper rear side of the leaf collection chamber 9123. The lower rear side of the blade holder 9124 is rotatably connected to the cutter 9126 via a shaft 9125, forming a lever-type shearing structure.

[0064] The bottom end of the cutter 9126 is connected to the electric push rod 9127, and the electric push rod 9127 is locked and fixed inside the rotating base 9128. The rotating base 9128 is rotatably connected to the lower right side of the rear of the leaf collection chamber 9123. The cutting part of the cutter 9126 is arc-shaped, forming an angle with the arc-shaped part inside the blade holder 9124. Using the electric push rod 9127 as the driving source, the cutter 9126 is pushed to rotate around the shaft column 9125 by controlling the extension and retraction of the electric push rod 9127. It cooperates with the blade holder 9124 to complete a scissor-like cutting action, which can accurately cut tea samples from specific parts for subsequent analysis.

[0065] The workflow of this invention is as follows: The system collects data through fixed sensors and the camera 7 and humidity sensor 58 of the mobile robot. After intelligent diagnosis by the data analysis module, if pests and diseases are found, a pesticide application instruction is generated. The instruction execution module controls the robot to navigate to the target area. The support and humidity detection structure 5 can raise the working platform and detect the soil condition. The spraying structure 8 adjusts the nozzle spacing for precise pesticide application. If sampling is required, the sampling structure 9 can extend and cut tea samples. All data in the process is recorded and can be traced through blockchain.

[0066] The specific working principle of the tea garden monitoring robot of the present invention is as follows:

[0067] First, after receiving instructions from the management system, the robot's mobile platform 1 starts up via four independent servo motors-driven omnidirectional wheels 2. Utilizing the unique mobility of the omnidirectional wheels 2, it precisely navigates to the target work area within the narrow rows of tea bushes. Subsequently, the moisture detection structure 5 begins operation. The first motor 52 drives the inner threaded cylinder 55 to rotate via the first bevel gear 53 and the second bevel gear 54, forcing the threaded screw 56, carrying the bottom soil insertion assembly 57, to vertically insert into the soil to the location where moisture needs to be detected. Then, the starting motor 573 is controlled, causing the threaded rod 574 to rotate and further shift the inner cylinder 575 downwards from within the middle cylinder 572. After the inner cylinder 575 moves downwards, the moisture sensor 58 is exposed to detect soil moisture and measure the moisture data of the deep soil layers.

[0068] Secondly, when the working height needs to be adjusted, the support and moisture detection structure 5 performs a lifting action: as the screw 56 moves upward, the push plate 59 at its top rises accordingly, pushing the surrounding X-folding frame 510 to unfold, thereby lifting the upper platform 513 and the horizontal plate 6 together upward through the upper support rod 512 and the lower support rod 511, so that the camera 7 installed at the bottom of the horizontal plate 6, the top spraying structure 8 and sampling structure 9 can be raised accordingly, flexibly adapting to different heights of the tea tree canopy.

[0069] Third, when the system command requires precise application of pesticides, the spraying structure 8 begins to operate: the two second motors 82 on the support 81 drive the two lead screws 84 to rotate synchronously through two sets of gears 83, which in turn drive the internal thread slider 85 to move; the movement of the internal thread slider 85 is transmitted to the support plate 87 through the universal joint 86, and the support plate 87, under the constraint of the V-shaped plate 88 and the slot frame 89, drives the nozzle 810 installed on it to perform precise opening and closing actions; after adjusting the position of the nozzle 810, the liquid pump in the pesticide tank 3 continuously delivers the pesticide to the nozzle 810, realizing precise spraying with adjustable spray width and direction.

[0070] Fourth, when sample collection is required, the sampling structure 9 is activated: the third motor 93 drives the screw rod 95 to rotate, causing the entire support seat 97 to move smoothly forward horizontally along the guide rod 92; at the same time, the fourth motor 94 drives the sliding key rod 98 and the worm gear sleeve 99 to rotate, which drives the L-shaped rod 911 and the shearing assembly 912 to rotate in the vertical plane through the worm wheel 910, so as to precisely adjust the angle; after the angle is determined, the electric push rod 9127 retracts, driving the cutter 9126 to rotate around the shaft column 9125, and cooperates with the blade holder 9124 to complete the shearing action. The cut tea sample falls into the leaf collection chamber 9123, completing the automated sampling.

[0071] The present invention also provides a smart tea garden management system for implementing the above-described method, the system comprising:

[0072] The data acquisition module is used to collect environmental data through multiple sensors deployed in the tea garden (fixed sensors and sensors on the tea garden monitoring robot);

[0073] The data transmission module is used to transmit environmental data to the data processing unit;

[0074] The data analysis module is used to analyze environmental data using artificial intelligence models to identify the growth status and potential risks of tea trees.
