Description

Technical Field

[0001] The present invention relates to the technical field of banana planting, and in particular to a banana planting lodging prevention and yield-increasing system and method. Background Art

[0002] Bananas are fast-growing, fast-growing, high-yielding, year-round supply trees with excellent economic returns, earning them high attention from banana-producing countries and farmers. However, bananas are prone to lodging during cultivation. The main reasons for this are: First, banana plants are tall, ranging from 2.5 to 5.0 meters. Their pseudostems, formed by petioles, gradually decrease in width from bottom to top and contain high water content, making them susceptible to breakage. Second, banana bunches are terminal and heavy. As the bunches increase in weight during maturity, the plant's center of gravity shifts upward, placing increasing pressure on the pseudostems and making them prone to lodging. Third, banana leaves are large, and severe convective weather (such as thunderstorms, high winds, hail, and short bursts of heavy rainfall) can significantly impact lodging in banana cultivation. Strong winds can cause banana plants to fall, while heavy rainfall can lead to soil loosening or erosion, which can also cause lodging. These factors can lead to reduced or even complete banana production, or even severe economic losses.

[0003] Currently, banana plant lodging prevention methods primarily involve staking and rope-tying. The staking method involves inserting support stakes (such as bamboo poles or wooden stakes) next to the banana tree and tying the banana pseudostem to the stake with a rope. The rope-tying method involves tying a rope around the upper part of the pseudostem and pulling the other end diagonally downward to secure it to an anchor point (a ground spike or the base of another banana plant stem). These two lodging prevention methods primarily address the lodging problem that occurs after bananas have set fruit but before harvest. These measures are typically implemented before bud formation to prevent lodging after bud formation. However, in recent years, global extreme weather has become increasingly frequent, with wind damage and thunderstorms occurring at varying times. Typhoons and thunderstorms frequently strike bananas during their vegetative and active growth period (before bud formation). Without rope-tying or staking to prevent lodging, banana plantations have collapsed, leaving growers devastated. If ropes or stakes are used to prevent bananas from falling during their vegetative or vigorous growth phase, the increasing height and width of the banana pseudostems can easily be affected by the ropes, affecting their growth. The ropes can also easily become embedded in or cut the pseudostems, posing a risk of pathogen infection. Furthermore, when wind damage strikes, the ropes can't be adjusted flexibly, promptly, or accurately, effectively preventing the banana plants from falling. This approach is inaccurate and inefficient, and labor-intensive and time-consuming. Once the bananas have budded and fruited, the existing rope or stake methods become ineffective, requiring constant manual adjustment of the rope's position and angle of force, which is labor-intensive and expensive.

[0045] Example

[0046] like Figures 1 to 7 As shown, a banana planting anti-lodging and yield-increasing system includes an adaptive clamping device 100 clamped on a banana tree and used to control the inclination angle of the banana tree. The adaptive clamping device 100 is provided with a plurality of sub-control devices 200, and the sub-control device 200 is electrically connected to the adaptive clamping device 100. The sub-control device 200 is electrically connected to an external server. The sub-control device 200 is used to receive feedback signals from the adaptive clamping device 100 and control instructions from the server, and control the adaptive clamping device 100 to adjust the clamping height and clamping force of the banana tree through the control instructions. The adaptive clamping device 100 can make corresponding adjustments to the clamping force and height according to the growth status of the clamped banana tree and the impact of the environment on it.

[0047] The system also includes a drone 400 equipped with a camera 300. The drone 400 is used to move the camera 300 and record the GPS coordinates of each banana tree shooting point. The camera 300 is also used to obtain images of the banana trees.

[0048] Preferably, it also includes a coordinate database, an image database, an inclination angle database, a bend height database and an image processor, wherein the coordinate database is used to store the GPS coordinates, the image database is used to store the banana tree image, the image processor is used to calculate the inclination angle and bend height value of the banana tree according to the banana tree image, the inclination angle database is used to store the inclination angle, and the bend height database is used to store the bend height value. The server is electrically connected to the camera 300, the drone 400, the coordinate database, the image database, the inclination angle database, the bend height database and the image processor, and the image processor The device is electrically connected to the image database, the inclination angle database and the bend height database. The server is used to receive the GPS coordinates, the banana tree image, the inclination angle and the bend height value, and transmit the GPS coordinates and the banana tree image to the coordinate database and the image database respectively, and send control instructions to the sub-control device 200 based on the inclination angle and the bend height value. Furthermore, the sub-control device 200 includes a microcontroller and a power supply. The microcontroller is electrically connected to the adaptive clamping device 100, the power supply and the server, and the power supply is electrically connected to the adaptive clamping device 100 to provide electrical energy.

[0049] In some preferred embodiments, the adaptive clamping device 100 includes a support clamping mechanism 110, a correction clamping mechanism 130, and a support adjustment mechanism 140. The support clamping mechanism 110 is clamped at the bending point of the banana tree. Furthermore, the correction clamping mechanism 130 includes two SMA adaptive clamping jaws, each of which includes an arc-shaped SMA spring piece 131, a first buffer rubber layer 132, and a first contact rubber layer 133 connected in sequence. A plurality of first pressure sensors 134 are provided in the first buffer rubber layer 132. First connecting seats 135 are provided on opposite sides of the arc-shaped SMA spring piece 131. The two SMA adaptive clamping jaws are connected by a telescopic clamping portion, and the telescopic clamping portion includes a micro motor 136 and a threaded rod 137. The threaded rod 137 is installed on the output end of the micro motor 136. The micro motor 136 is driven to drive the two SMA adaptive clamping jaws to move closer or farther away from each other.

[0050] One end of the support adjustment mechanism 140 is rotationally connected to the support clamping mechanism 110, and the other end is rotationally connected to the SMA adaptive clamping claw; the support clamping mechanism 110, the arc-shaped SMA spring 131, the first pressure sensor 134, the micro motor 136 and the support adjustment mechanism 140 are all electrically connected to the sub-control device 200. During the clamping process, the clamping force can be adjusted accordingly according to the pressure signal fed back by the first pressure sensor 134.

[0051] In some preferred embodiments, the support and clamping mechanism 110 is fixedly installed on the ground at the root of the banana tree through a connecting assembly. The support and clamping mechanism 110 includes a base plate 111, a drive adjustment portion, and a support clamping jaw. The base plate 111 is provided with a through slot 112 for the banana tree to pass through and slide slots 113 located at opposite ends of the through slot 112. The support clamping jaw is slidably installed on the slide slot 113. The support clamping jaw includes an arc-shaped rebound metal sheet 114, a second buffer rubber layer 115, and a second contact rubber layer 116 connected in sequence. The bottom end of the arc-shaped rebound metal sheet 114 is provided with a slider slidably connected to the slide slot 113. The second buffer rubber layer 115 is provided with a plurality of second pressure sensors 117. The second pressure sensors 117 are used to collect the clamping force of the support clamping jaw on the banana tree and feed the collected value back to the sub-control device 200.

[0052] The driving and adjusting portion includes a first dual-axis motor 118, a driving wheel 119, a driven wheel 120, an adjusting screw 121, a first rotating seat 122 and an adjusting slider 123. The first dual-axis motor 118 is mounted on the base plate 111. The driving wheel 119 is provided on both output ends of the first dual-axis motor 118. The adjusting slider 123 is connected to the supporting clamp and is slidably arranged on the slide groove 113. The first rotating seat 122 is mounted on the base plate 111. The adjusting screw 121 is rotatably mounted on the first rotating seat 122. The adjusting slider 123 is threadedly connected to the adjusting screw 121. The driven wheel 120 is mounted on the adjusting screw 121. The driven wheel 120 and the driving wheel 119 are connected by a synchronous belt.

[0053] The sub-control device 200 controls the first dual-axis motor 118 based on a preset clamping threshold range to drive the adjustment slider 123 to slide on the slide groove 113 to adjust the clamping force of the supporting clamp on the banana tree. When the clamping force collected is less than the clamping threshold range, the sub-control device 200 controls the two supporting jaws to retract to prevent the adaptive clamping device 100 from slipping. When the clamping force collected is greater than the clamping threshold range, the sub-control device 200 controls the two supporting jaws to move away from each other to prevent the supporting jaws from damaging the banana tree stem when the banana tree stem becomes larger. The first pressure sensor 134 is divided into two groups. The first pressure sensor 134 in the SMA adaptive clamp below the banana tree is the first group, and the first pressure sensor 134 in the SMA adaptive clamp above the banana tree is the second group. When the pressure collected by the second group of the first pressure sensors 134 is greater than the clamping threshold preset in the sub-control device 200, the sub-control device 200 energizes and heats the arc-shaped SMA spring 131 through PWM pulse width modulation, and transmits control instructions to the micro motor 136. The micro motor 136 drives the threaded rod 137 to rotate, thereby making the two SMA The sub-adaptive clamping claws move away from each other, and the arc-shaped SMA spring 131 deforms, its radius increasing to match the increased radius of the banana tree stem, preventing the clamping claws from damaging the banana tree stem. Specifically, the arc-shaped SMA spring 131 is a nickel-titanium alloy that achieves one-way expansion through thermomechanical training. When the banana tree tilts, the sub-control device 200 controls the two second dual-axis motors 142 respectively to adjust the lengths of the two support adjustment mechanisms 140 to correct the banana tree's tilt angle. Furthermore, the server can also access the local weather forecast network to obtain real-time weather changes in the banana planting area. The sub-control device 200 is preset with an extreme clamping threshold. When the server receives a weather forecast signal alert for strong winds, typhoons, heavy rains, etc., the sub-control device 200 is triggered to adjust the clamping force of the adaptive clamping device 100 based on the extreme clamping threshold. This increases the clamping force on the banana pseudostem without damaging the banana pseudostem, thereby improving the banana pseudostem's ability to prevent lodging in severe weather.

[0054] It is worth mentioning that, since the main stem of the banana tree is covered with a smooth plant outer skin, in order to ensure greater stability during the clamping process, the inner sides of the first contact rubber layer 133 and the second contact rubber layer 116 are both provided with anti-slip stripes.

[0055] In some preferred embodiments, the support adjustment mechanism 140 includes a hollow adjustment column 141, a second dual-axis motor 142, an adjustment push rod 143 and a second rotating seat 144. The second dual-axis motor 142 is fixedly arranged in the hollow adjustment column 141, and its two output ends are respectively threadedly connected to one of the adjustment push rods 143. The adjustment push rod 143 is slidingly connected to the hollow adjustment column 141, and its other end is connected to the second rotating seat 144. The two second rotating seats 144 are respectively rotatably connected to the arc-shaped SMA spring piece 131 and the first rotating seat 122. The second dual-axis motor 142 is electrically connected to the sub-control device 200. Through the support adjustment mechanism 140, the supported height is adjusted accordingly according to the growth condition of the banana tree, and it has good adaptability.

[0056] In some preferred embodiments, a wireless charging module is further included, which includes two helipads 500, a transmitting device arranged in the helipads 500, and a receiving device arranged in the drone 400. The two helipads 500 are respectively arranged at both ends of the diagonal line of the banana tree planting area, and the banana planting area is regularly patrolled and inspected by the drone 400.

[0057] It also includes a solar charging module, which includes several photovoltaic panels 600, a photovoltaic junction box 610 and a photovoltaic controller 620. Several photovoltaic panels 600 are set up around the planting area of banana trees and are electrically connected to the photovoltaic junction box 610. The photovoltaic junction box 610 is electrically connected to the photovoltaic controller 620. The photovoltaic controller 620 is electrically connected to the transmitting device and the sub-control device 200. The solar charging module can be used as a DC power input module of the transmitting device. By setting up the solar charging module, solar power generation is fully utilized, the system's demand for municipal electricity is reduced, and it is beneficial to energy conservation, emission reduction and cost reduction.

[0058] The embodiment of the present invention further provides a method for preventing lodging and increasing yield in banana planting, which uses the above-mentioned system for preventing lodging and increasing yield in banana planting, and the method includes the following steps:

[0059] S1: Divide the planting area of N banana trees into a rectangular array and dig holes for planting:

[0060] Different banana plant row spacings are selected based on different banana orchards and banana varieties. For example, the row spacing for ordinary banana orchards is 2.2-2.5 meters, the row spacing for dwarf and densely planted banana orchards is 1.8-2.5 meters, and the row spacing for mechanized harvested banana orchards and banana orchards with wide and narrow rows is 3-5 meters.

[0061] S2: The drone 400 performs an initial cruise and stores the GPS coordinates of N banana tree photography points into a coordinate database in N groups. The drone 400 forms a drone cruise route based on the GPS coordinates. The camera 300 captures initial images of the N banana trees and stores the N acquired initial images into an image database in N groups. The image processor acquires the N initial images from the image database and generates initial tilt angles of the N banana trees. The N initial tilt angles are stored into a tilt angle database in N groups.

[0062] The coordinate database is divided into N groups, each group is used to store the GPS coordinates corresponding to a banana tree. The image database is also divided into N groups, each group is used to store the initial image corresponding to a banana tree. The tilt angle database is also divided into N groups, each group is used to store the initial tilt angle corresponding to a banana tree. The coordinate database, image database and tilt angle database are in one-to-one correspondence, achieving coordinate-image-tilt angle matching.

[0063] S3: The drone 400 cruises at first time intervals based on the drone cruise route. The camera 300 acquires first images of N banana trees and stores the N first images in N groups in the image database. The image processor acquires the N first images from the image database, generates first tilt angles of the N banana trees, and stores the first tilt angles in N groups in the tilt angle database. The first time interval is one week.

[0064] S4: Based on the first tilt angle difference, it is determined that the banana tree is tilted. Based on the initial tilt direction of the banana tree, adaptive clamping devices 100 are installed on the banana trees until all banana trees are installed with the adaptive clamping devices 100. The support clamping mechanism 110 is clamped at the bend of the banana tree, and the clamping force is adaptively adjusted using the second pressure sensor 117, the sub-control device 200, and the first dual-axis motor 118. The correction clamping mechanism 130 is clamped above the bend of the banana tree, and the clamping force is adaptively adjusted using the first pressure sensor 134, the sub-control device 200, and the micromotor 136. The lengths of the two support adjustment mechanisms 140 are respectively adjusted so that the correction clamping mechanism 130 fits the banana tree. Based on the initial tilt direction, the shooting point of the corresponding banana tree is adjusted, and the coordinate database updates the GPS coordinates of the N banana tree shooting points to form a first drone cruising route. The first tilt angle difference is the difference between the first tilt angle and the initial tilt angle.

[0065] S5: The drone 400 cruises at second time intervals based on the first drone's cruise route. The camera 300 obtains second images of N banana trees and stores them in the image database in N groups. The image processor obtains N second images from the image database and generates second tilt angles of the N banana trees. The image processor stores the N second tilt angles in the tilt angle database in N groups. A second tilt angle difference is obtained by subtracting the second tilt angle at a previous time point from the second tilt angle at a later time point. The second tilt angle differences are accumulated to obtain an accumulated tilt angle value. When the accumulated tilt angle value is greater than 5°, the server sends a control command to the sub-control device 200. The sub-control device 200 controls the length of the support adjustment mechanism 140 by controlling the second dual-axis motor 142, thereby correcting the tilt angle of the banana trees to prevent them from falling over. The second time period is 2-3 days.

[0066] Preferably, in said S5, the following steps are further included:

[0067] Based on the acquired second image, the image processor generates a height value of the bend of the banana tree, and divides the bend height values into N groups and stores them in a bend height database. The height difference value is calculated by subtracting the bend height value at a previous time point from the bend height value at a later time point, and several height difference values are accumulated to obtain an accumulated height difference value. When the accumulated height difference value is greater than 15 cm, the server sends a control instruction to the sub-control device 200, and the sub-control device 200 controls the adaptive clamping device 100 to move a first distance upward along the banana tree, wherein the first distance is 10-15 cm.

[0068] In summary, the present invention provides a banana planting lodging prevention and yield-increasing system. A drone equipped with a camera cruises through a banana planting area and obtains the real-time status (image, coordinates, etc.) of each banana tree. An image processor processes the banana tree image to obtain the tree's tilt angle. An adaptive clamping device clamped on the banana tree performs corresponding auxiliary adjustments to the banana tree (height, tilt, and stem diameter changes due to growth, etc.).
