Technical Field

[0001] The present invention belongs to the technical field of plant grafting, and more particularly, relates to a multifunctional plant grafting platform. Background Art

[0002] Plant grafting technology is a core means of improving crop resistance, yield, and quality, but there are still three major systemic defects in the traditional operation mode: 1. Grafting quality relies on manual visual inspection, which makes it difficult to identify defects such as interface misalignment in real time, resulting in defective seedlings flowing into the maintenance link; there is a lack of screening mechanism for diseased plants before grafting, which causes chain infection and death after mixing, resulting in a large workload. 2. Grafting operations, tool disinfection, interface quality inspection, and seedling watering are scattered on different platforms, making them inconvenient to operate; 3. Fixed-height operating tables force operators of different body shapes to bend over for long periods of time, causing lumbar injuries and increasing the difficulty of work. Based on the above-mentioned defects, it is urgent to provide a multifunctional and easy-to-use plant grafting platform. Summary of the Invention

[0006] Preferably, a transparent positioning slot is provided at the exit of the grafting operation area, and horizontal reference lines are marked on the side walls of the bracket on both sides of the slot; an infrared pair of tubes is embedded in the slot, and shooting is triggered when the plant stem is inserted to block the light beam; the first camera is set on the other side wall relative to the reference line, and the captured image covers the stem joint and the reference line.

[0007] Preferably, a V-shaped bracket is provided at the entrance of the grafting operation area, and the surface is coated with RAL1021 yellow matte coating; a 120° wide-angle second camera is fixed 20 cm above the bracket to collect plant images.

[0008] Preferably, the AI ​​quality inspection module extracts the joint contour line from the image and calculates the angle θ between the joint contour line and the reference line; when |θ|>5°, the verticality is determined to be abnormal.

[0009] Preferably, the AI ​​quality inspection module calibrates the lighting based on a yellow background, converts the image to the HSV color model, and dynamically adjusts the saturation threshold to identify the diseased area; if the diseased area accounts for >5%, an alarm is issued.

[0010] Preferably, the electronic device interface displays the entrance and exit views of the grafting operation area in partitions; when an abnormality occurs, a red frame flashes on the edge of the corresponding view, and a warning icon is superimposed on the abnormal part until the user confirms.

[0011] Preferably, multiple groups of proximity sensors and multiple groups of downwardly inclined injection pipes are provided in the irrigation trough, one group of proximity sensors corresponds to one group of injection pipes, the water outlet of the injection pipe is located above the matrix of the grafted seedling tray, and when any group of proximity sensors detects that the grafted seedlings have been moved in, the corresponding group of injection pipes is automatically triggered to irrigate with nutrient solution or clean water.

[0012] Preferably, an infrared transmitter is embedded in the upper part of the side wall of the disinfection tank, and an infrared receiver is provided at a corresponding position on the opposite side wall; When the sliding cover is closed, the metal frame of the cover blocks the entire light beam; or when a tool or hand is placed in, the light beam intensity is blocked by >80% and lasts for 0.5 seconds, which triggers the atomizing nozzle to spray alcohol spray; the atomizing nozzles are staggered and distributed 4 times around the wall of the disinfection tank.

[0013] Preferably, the side sensors of the grafting operation area are two sets of infrared ranging sensors (accuracy ±2mm), which are horizontally installed at the edge of the platform at a height of 70cm from the ground; The first set of sensors measures the operator's waist height (60-100 cm from the ground), and the second set measures knee height (40-50 cm from the ground); The processor calculates the platform target height according to the formula: H=0.6×H w +0.4×H k −5, in cm.

[0015] The present invention arranges grafting operation, tool disinfection, interface quality inspection, and seedling watering to be performed on the same platform, which is convenient for observation and control.

[0016] The present invention sets a proximity sensor in the irrigation trough to link the liquid injection pipe, so that the grafted seedlings can be automatically watered after being moved in, reducing manual intervention. The disinfection trough can not only disinfect tools, but also start disinfection when hands are placed in it, which is conducive to blocking pollution.

[0024] See also Figure 1 As shown, the present invention discloses a multifunctional plant grafting platform, which includes: Platform body 15; The partition function module includes a grafting operation area located on the first side of the platform body, which is equipped with electronic equipment fixed by a clamp, a lighting tube 3, and a dual-camera system; a plant treatment area located on the second side of the platform body, which includes a watering trough 11 and a disinfection trough 16; the dual-camera system includes a first camera 10 aimed at the exit of the grafting operation area, which is used to capture images of the joint part of the plant after grafting; and a second camera 2 aimed at the entrance of the grafting operation area, which is used to capture images of the health status of the rootstock and scion to be grafted; The AI ​​quality inspection module is executed by the processor and identifies the verticality of the scion and rootstock based on the first camera image; identifies the characteristics of plant disease spots based on the second camera image; generates an abnormality prompt signal and outputs it to the electronic device display interface; Among them, the exit of the grafting operation area is provided with a transparent positioning slot, and the side walls of the bracket 8 on both sides of the slot are marked with horizontal reference lines 9; an infrared tube is embedded in the slot, and when the plant stem is inserted into the light beam, the camera is triggered to shoot; the first camera 10 is set on the other side wall relative to the reference line 9, and the captured image covers the stem joint and the reference line; A V-shaped bracket is installed at the entrance of the grafting operation area, and its surface is coated with RAL1021 yellow matte coating. A second camera with a 120° wide angle is fixed 20 cm above the bracket to capture plant images. The AI ​​quality inspection module extracts the joint contour from the image and calculates the angle θ between it and the horizontal reference line. When |θ|>5°, it determines that the verticality is abnormal. The AI ​​quality inspection module calibrates the lighting using a yellow background as a reference, converts the image to the HSV color model, and dynamically adjusts the saturation threshold to identify diseased areas. If the diseased area accounts for >5%, an alarm is issued. Among them, the electronic device interface partitions and displays the entrance and exit views of the grafting operation area; when an abnormality occurs, a red frame flashes on the edge of the corresponding view, and a warning icon is superimposed on the abnormal part until the user confirms.

[0025] According to one embodiment of the present invention, the platform body is welded from stainless steel to form a support platform, with an epoxy resin anti-rust coating sprayed on the surface. The functional zoning modules include: a grafting area located on the left long side of the platform body, equipped with an adjustable pressure clamp (pneumatic parallel clamps are optional), LED strip lighting, and a dual-camera system; a plant treatment area located on the right long side, comprising a PVC irrigation trough and a 304 stainless steel disinfection trough. A transparent acrylic positioning slot is installed at the exit of the grafting area, with a 2mm-wide horizontal reference line laser-etched on the sidewall. A slotted infrared pairing tube is embedded in the slot, triggering the first camera 10 to capture images when a plant stem is inserted into the slot, blocking the light path. An aluminum alloy V-shaped bracket 5, painted a matte yellow RAL1021 color, is installed at the entrance of the grafting area. A second camera with a 120° wide-angle lens is fixed 20 cm above the bracket via a support rod 1. The electronic device can be an industrial tablet computer, with its interface divided into two areas: the right side displays a real-time view of the grafting area exit, and the left side displays a view of the plant treatment area entrance.

[0026] The sidewalls of the bracket 8 on either side of the slot are marked with a horizontal reference line 9, located 5 mm above the plant insertion path to ensure unobstructed image capture. The first camera, a 5-megapixel CMOS sensor, is mounted on the wall opposite the reference line, with the lens' central axis at a 90° angle to the reference line. Its field of view covers the stem junction and the entire reference line. An infrared pairing tube 7 is embedded in the slot. When a plant stem inserts and blocks the beam, the infrared pairing tube detects that the stem insertion has been blocked for ≥0.5 seconds, triggering the first camera to capture an image within 10 milliseconds. The second camera, equipped with an F2.0 aperture and automatic white balance, continuously captures plant images at 30 fps against the yellow-coated background of the V-shaped bracket. When the seedling tray to be grafted is placed in the entrance bracket of the grafting operation area, the pressure sensor 4 at its base triggers a single-frame capture by the second camera when a load greater than a preset threshold, such as 30 N or manually initiated. Images from both cameras are transmitted to the electronic device via a USB 3.0 interface, with a resolution of both cameras set to 1920 × 1080 pixels.

[0027] Verticality detection algorithm: Extract the outline of the joint part in the image and fit its main axis equation; read the slope k of the reference line in the image coordinate system and calculate the angle between the two lines θ=arctan|(k1-k2) / (1+k1k2)| (unit: degree), where k1 is the main axis slope of the outline of the grafting joint part, and k2 is the slope of the horizontal reference line marked on the bracket side walls on both sides of the slot. When θ>5°, the verticality is determined to be abnormal and the code E01 alarm is sent to the operation interface. Disease spot recognition algorithm: Intercept the yellow background area of ​​the V-shaped bracket (RGB∈[240,205,75]±5), convert the image to the HSV color model; extract the saturation value S of a single pixel in the image in the HSV color model. pixel , mark satisfies S pixel threshold The pixel area is the candidate lesion area. Calculate the lesion pixel ratio η = (number of lesion pixels / total number of pixels) × 100%. When η > 5%, an E02 alarm is issued. Upon receiving the alarm signal, the electronic device generates a 3px wide, flashing red border around the edge of the corresponding view and overlays an icon on the abnormal area: a tilt angle symbol for vertical anomalies and a speckled pattern for lesion anomalies. This warning is released until the user clicks the confirmation button.

[0028] The present invention realizes the process of plant health screening before grafting and interface quality inspection after grafting through partition collaborative design and dual-channel image analysis; the combination of mechanical positioning and algorithm detection can reduce the missed judgment rate of manual visual inspection; the automated trigger mechanism reduces operation interruptions and improves work continuity.

[0029] 1. Source of the perpendicularity test formula: The formula for the angle between two lines is derived from the relationship between the slopes of two lines in analytic geometry: θ = arctan|(k1-k2) / (1+k1k2)|. Dimensional verification: The slope k is the dimensionless ratio (Δy / Δx), and the arctan output angle unit is degrees (°), which conforms to dimensional consistency.

[0030] Extract the joint contour line: Calculate the image gradient using the Sobel operator, use the pixel gray value change rate ≥ 50 (range 0-255) as the edge judgment threshold, and connect continuous edge points to generate the contour line.

[0031] Fit Principal Axis Lines: Apply the least squares method to the set of contour points to solve the linear equation y=k1x+b.

[0032] The baseline slope k2 is calculated from the image coordinate points (x1, y1) and (x2, y2) of the laser-marked line: k2 = (y2-y1) / (x2-x1).

[0033] 2. Lesion recognition algorithm: ​Step 1: Lighting compensation and color conversion: Intercept the yellow background area of ​​the V-shaped bracket (RGB∈[240,205,75]±5, calculate the RGB mean of this area as the reference value (e.g. (245, 210, 80)); perform white balance correction on the entire image: R{norm} = R{pixel} × 128 / R{avg}; / / R{avg} is the R mean of the yellow area (e.g., 245); G{norm} = G{pixel} × 128 / G{avg}; B{norm} = B{pixel} × 128 / B{avg}; Among them, the original RGB pixel values ​​are R{pixel}, G{pixel}, B{pixel}, and the corrected RGB values ​​are R{norm}, G{norm}, B{norm}; then the corrected image is converted to the HSV color model.

[0034] Step 2: Dynamic threshold setting: Calculate the V channel (brightness) mean V in the same yellow area avg , calculate the saturation threshold S threshold : if V avg ≤ 100, S threshold = 40; if 100 <V avg <180, S threshold = 40 + 0.25 × (V avg - 100); / / Note: Coefficient 0.25 = (60-40) / (180-100); if V avg ≥ 180, S threshold = 60; Step 3: Spot detection: Scan all pixels in the image and mark them as satisfying S pixel threshold The area with marked pixels is taken as the candidate area of ​​lesion, and the proportion of lesion pixels is calculated as follows: η = (number of lesion pixels / total number of pixels) × 100%; Step 4: Alarm determination: If η>5% → trigger E02 alarm, the electronic device displays a red mask in the diseased area with a flashing frequency of 2Hz.

[0035] Verticality detection example: Input: Contour line slope k1=0.35, baseline slope k2=0 (horizontal line).

[0036] ​Calculation: θ = arctan|(0.35-0) / (1+0.35×0)| = arctan(0.35)≈19.3° Result: Because 19.3°>5°, the E01 alarm is triggered.

[0037] Examples of lesion identification: Input data: Yellow area RGB mean: (242,208,78); Yellow area V avg =152 (under strong fill light); image resolution 1280×720 (total pixels 921600); Processing process: 1. White balance correction: R{norm}=R{pixel}×128 / 242; G{norm}=G{pixel}×128 / 208; B{norm}=B{pixel}×128 / 78; Eliminate lighting color casts.

[0038] 2. Dynamic threshold calculation: ∵100<152<180; ∴S threshold =40+0.25×(152-100)=40+13=53; 3. Disease spot detection: Scanning found 58400 pixels meeting S pixel <53; Proportion calculation: η=(58400 / 921600)×100%≈6.3%; Output: ∵6.3%>5% ∴The E02 alarm is triggered. The interface displays: the plant image is superimposed with a red lesion mask, and the status bar displays "Lesion percentage: 6.3% > Threshold 5%".

[0039] According to another embodiment of the present invention, the irrigation trough is integrally formed using PVC material, and the upper opening of the irrigation trough 11 can be slid along the platform plane to be provided with an irrigation trough cover 22 so as to be covered and used as needed. For example, when the irrigation trough is not in use, the upper opening of the irrigation trough 11 is covered by the irrigation trough cover 22 to form a larger platform plane, and to prevent dust, impurities or other influences; when in use, the upper opening is opened and the grafted plants are placed in for watering. The inclination angle of the bottom of the irrigation trough is designed to be 5°±1° to facilitate the collection and discharge of liquid. A group of proximity sensors 12 includes an infrared transmitter and an infrared receiver, and multiple groups of infrared transmitters and infrared receivers, as well as multiple groups of injection pipes 13, are symmetrically installed on the inner walls on both sides of the trough body. A group of proximity sensors corresponds one to one with a group of injection pipes. The injection pipe is made of 304 stainless steel pipe with an inner diameter of 4mm, fixed to the side wall of the trough body at an inclination angle of 30°, and the water outlet is 3cm high from the surface of the grafted seedling tray matrix. The sensor signal line is connected to the PLC controller. When it is detected that the grafted seedlings move into the groove and block a pair of sensors for ≥0.5 seconds, it is determined to be a valid trigger signal.

[0040] The injection tube is connected to an external liquid supply system via a connector. The supply system can be controlled by a peristaltic pump or solenoid valve. After receiving the sensor signal, the PLC controller activates the supply system with a delay of 0.3 seconds. The nutrient solution or water is continuously applied at a flow rate of 0.5 L / min for 5 seconds. An umbrella-shaped diverter (12 holes with a diameter of 0.8 mm) is installed at the outlet of the injection tube to ensure that the liquid evenly covers an area with a diameter of 10 cm. After the watering is completed, the residual liquid at the bottom of the tank is discharged into a recovery container through the drainage hole.

[0041] As shown in the figure, a set of proximity sensors 12 and a corresponding set of injection pipes 13 form a combined module 14. The set of injection pipes that detect an obstruction is used to deliver liquid for irrigation, reducing waste and improving efficiency. After each irrigation session, the system automatically records the timestamp and trigger sensor number, and historical records can be viewed through the electronic device interface.

[0042] This invention utilizes a proximity sensor linked to a liquid injection mechanism to achieve immediate irrigation after transplanting the grafted seedlings, reducing manual intervention. The tilted trough and diverter design ensures uniform liquid penetration, while a dual misjudgment prevention mechanism reduces the risk of resource waste. This design helps maintain substrate moisture stability during the initial transplanting phase.

[0043] According to another embodiment of the present invention, the disinfection tank is made of 304 stainless steel, has a depth of 15 cm, and measures 25 cm x 20 cm. An infrared transmitter is embedded 2 cm below the upper edge of the left side wall of the tank, and an infrared receiver 18 is installed on the upper edge of the right side wall, corresponding to the infrared transmitter. The optical axes of the transmitter and receiver are horizontally aligned, with a spacing of 20 cm. An aluminum alloy sliding cover 19 is installed on the top of the tank. The lower edge 20 of the cover 19 is 3-4 cm wide, completely covering the tank opening when closed and blocking all infrared beams.

[0044] The infrared receiver continuously monitors the light intensity signal, and the initial unobstructed state is set to a reference value of 100%. When the light intensity drops to ≤20% (i.e., the obstruction rate is ≥80%) and lasts for 0.5 seconds due to obstruction, the control circuit is triggered to start the disinfection program. The four atomizing nozzles 17 are staggered along the inner wall of the disinfection tank, and the installation height is 5-10 cm from the bottom of the tank. After triggering, the nozzle sprays 75% medical alcohol solution, with a single spray volume of 0.5 ml and a duration of 2 seconds; a temperature sensor is embedded in the side wall of the disinfection tank, and the spray function is automatically locked when the ambient temperature is greater than 28°C. Open flames are prohibited within a radius of 1 meter.

[0045] The present invention utilizes a dual-condition trigger mechanism based on infrared light intensity threshold and duration, facilitating identification of hand or tool insertion. The staggered distribution of atomizing nozzles 17 facilitates comprehensive disinfection. This approach reduces the risk of hand contamination during switching operations.

[0046] According to one embodiment of the present invention, two sets of infrared ranging sensors are horizontally mounted at the four corners of the platform, 70 cm ± 1 cm above the ground. The first set of sensors is mounted at the left and right front ends (for example, at the left and right ends of the grafting operation area), with a 90° beam angle, focusing on measuring the operator's waist height (corresponding to a range of 60-100 cm from the ground). The second set of sensors is mounted at the lower front ends of the platform, tilted downward at a 15° angle, measuring knee height (corresponding to a range of 40-50 cm from the ground). The sensor housing is made of aluminum alloy and has an IP65 protection rating. The measurement cycle is 10 times per second, and data is transmitted to the processor via the RS485 bus.

[0047] The processor performs height calculations: Get waist height measurement H w (take the average of the left and right sensors) and knee height H k (Take the average of the left and right sensors); Calculate the target height according to the formula: H (cm) = 0.6 × H w +0.4×H k −5 (cm); Control the scissor-type or four-gluing synchronous lifting frame 21 (optionally equipped with a 200kg electric actuator) to adjust to H ± 0.3 cm within 5 seconds, so that the grafting operation area is 5 ± 3 cm below the operator's elbow. Dimensional Verification: All variables are in cm, and the left and right dimensions of the formula are consistent.

[0048] The system sets a maximum lift speed of 3 cm / s. If an obstacle is detected within 10 cm of the platform edge (via an attached ultrasonic sensor), movement is immediately suspended. The operator can manually adjust the platform by ±5 cm through the electronic device interface, with manual adjustments taking precedence over automatic adjustments. The final height value and sensor data are recorded after each adjustment. Abnormal conditions (such as motor current exceeding the limit) trigger an E03 alarm code.

[0049] This invention uses multi-sensor collaborative measurement and ergonomic calculations to adapt to the comfortable operating height of operators of different body types. A safety protection mechanism prevents the risk of mechanical collisions. This design can reduce the load on the waist during long-term operation.

[0050] Calculation example: Input: H w =85cm (waist height), H k =45cm (knee height); Calculation: H = 0.6 × 85 + 0.4 × 45 - 5 = 51 + 18 - 5 = 64 cm; Output: Control the lifting frame to move to a height of 64cm, so that the grafting operation area is 5cm below the elbow.

[0051] The test results are as follows: Operator height Adjust the height of the rear elbow Meet the 5±3cm requirement 160cm 6.8cm yes It can be seen that through multi-sensor collaborative measurement and ergonomic formula calculation, the comfortable operating height can be adapted to operators of different body shapes, which is beneficial to reducing the waist load during long-term operation.

[0052] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiment. They can be applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
