[0038] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0039] Figure 1 The flowchart of an embodiment of a method for adjusting and controlling the amount of seedlings taken by a rice transplanter provided by the present invention is shown. The method for adjusting and controlling the amount of seedlings taken by a rice transplanter is executed by a vehicle controller. Figure 1 As shown, the following steps are included:

[0040] S1. Obtain a current average seedling density of the rice transplanter in a current seedling-picking area, and determine a current planting claw adjustment amount of the rice transplanter in the current seedling-picking area based on a target correlation relationship between the seedling density and the planting claw adjustment amount of the rice transplanter.

[0041] Among them, a rice transplanter is an agricultural machine used to insert seedlings into paddy fields or farmland according to predetermined row and plant spacing. The current seedling removal area is the area where the rice transplanter is currently preparing to remove seedlings. Different seedling removal areas correspond to different numbers of seedling trays, which are determined according to the target seedling removal quantity. The seedling density refers to the number of seedlings planted per unit area, usually in units of "plants / square meter". In this embodiment, the adjustment amount of the planting claws mainly involves the adjustment of the longitudinal seedling removal amount. The target association relationship defaults to a linear relationship or a functional relationship.

[0042] S2. Controlling the planting claw height adjustment mechanism through the seedling picking amount adjustment controller to lift and lower the planting claw of the rice transplanter according to the current planting claw adjustment amount, so as to adjust the seedling picking amount of the rice transplanter in the current seedling picking area.

[0043] The seedling quantity adjustment controller receives the planting claw adjustment value via the CAN network and drives the planting claw height adjustment mechanism to raise and lower the transplanter's planting claw according to the corresponding planting claw adjustment value, thereby adjusting the transplanter's seedling quantity. It should be noted that when the planting claw is controlled to rise, the transplanter's seedling quantity increases, and the degree of the planting claw's rise is proportional to the increase in the seedling quantity; when the planting claw is controlled to fall, the transplanter's seedling quantity decreases, and the degree of the planting claw's fall is proportional to the decrease in the seedling quantity.

[0044] The seedling removal adjustment controller is an embedded microcontroller or PLC that converts the current planting claw adjustment value received into a pulse signal or analog voltage signal, which is determined by the drive unit of the planting claw height adjustment mechanism. The drive unit of the planting claw height adjustment mechanism is a stepper motor, servo motor, or hydraulic cylinder, which drives the planting claw to move up and down according to the current planting claw adjustment value.

[0045] In an optional manner, the current seedling-picking area includes: a plurality of seedling-picking row areas corresponding to the seedling trays currently to be picked; and the step of obtaining the current average seedling density of the rice transplanter in the current seedling-picking area includes:

[0046] The current seedling density of the transplanter in the seedling picking row area corresponding to each seedling tray currently to be picked is obtained and averaged to obtain the current average seedling density.

[0047] The multiple seedling trays currently in the retrieval area are arranged perpendicular to the transplanter's path by default. This can be adjusted based on actual conditions and is not a limitation. The retrieval row area refers to the specific number of rows on the seedling tray that are picked up by the transplanter's retrieval mechanism. Each seedling tray corresponds to a retrieval row area, and each retrieval row area corresponds to a seedling density.

[0048] In an optional manner, the step of obtaining the current seedling density of the rice transplanter in the seedling picking row area corresponding to any seedling tray currently to be picked includes:

[0049] Using a visual detection device, a seedling image of the seedling picking row area corresponding to any current seedling tray to be picked is obtained, and combined with image processing technology, the current seedling density of the seedling picking row area corresponding to any current seedling tray to be picked is obtained.

[0050] The default visual inspection device is an industrial camera or millimeter-wave radar, installed above the transplanter's planting platform. Image processing techniques include grayscale processing, image denoising, image enhancement, shape feature extraction, and connected domain analysis to determine the seedling density in the selected row area.

[0051] In an optional manner, the step of determining the current adjustment amount of the transplanting claws of the rice transplanter in the current seedling removal area in combination with the target correlation relationship between the seedling density and the adjustment amount of the transplanting claws of the rice transplanter includes:

[0052] When the current average seedling density is within a preset seedling density range, the current average seedling density is substituted into the target association relationship to obtain the current planting claw adjustment amount of the rice transplanter in the current seedling-picking area.

[0053] The preset seedling density range can be determined based on actual conditions and is not limited here. Different seedling densities correspond to different planting claw adjustment amounts, which can be determined based on pre-calibrated target correlation relationships.

[0054] In an optional manner, the method further includes:

[0055] When the current average seedling density is not within the preset seedling density range, a fault prompt message is output.

[0056] The fault prompt information can be output through a display terminal connected to the vehicle controller. The default content of the fault prompt information is: "The seedling tray is not in place, please check whether the seedling tray is stuck or there is no seedling tray."

[0057] It should be noted that when it is determined that a fault prompt message is output, an audible and visual alarm may also be performed.

[0058] In an optional manner, the method further includes:

[0059] Obtaining a test average seedling density of the rice transplanter in a plurality of test seedling picking areas, and determining a test planting claw adjustment amount required to obtain a target seedling picking amount according to the test average seedling density in each test seedling picking area, so as to establish the target correlation relationship between the seedling density and the planting claw adjustment amount of the rice transplanter;

[0060] Among them, when the seedling amount obtained according to the average seedling density is less than the target seedling amount, the planting claws are controlled to be adjusted upward; when the seedling amount obtained according to the average seedling density is greater than the target seedling amount, the planting claws are controlled to be adjusted downward.

[0061] It should be noted that after the target association relationship is determined, in the actual adjustment and control process, each time the current average seedling density of the current area to be harvested is obtained, the current standard seedling quantity of the current area to be harvested is determined based on the product of the area of ​​the current area to be harvested and the current average seedling density, and the current standard seedling quantity is compared with the target seedling quantity. If the current standard seedling quantity is less than the target seedling quantity, the planting claws are controlled to adjust upward, reduce the seedling depth, and increase the single seedling quantity (to avoid missing seedlings); if the current standard seedling quantity is greater than the target seedling quantity, the planting claws are controlled to adjust downward, increase the seedling depth, and reduce the single seedling quantity (to prevent overcrowding); if the current standard seedling quantity is equal to the target seedling quantity, the planting claws are controlled to maintain the standard height value.

[0062] In an optional manner, the method further includes:

[0063] The current average seedling density and area of ​​the current area to be harvested are used to calculate the current amount of seedlings to be harvested in the area to be harvested, and the current average seedling density and the current amount of seedlings to be harvested in the area to be harvested are output and displayed.

[0064] The display terminal connected to the vehicle controller outputs the current average seedling density and the current seedling quantity in the current seedling-picking area. In addition, the target seedling quantity can also be displayed on the display terminal.

[0065] It should be noted that, in this embodiment, the rice transplanter will re-execute the solution of this embodiment every time the area to be taken is changed. Figure 2 As shown, in this embodiment, the amount of seedlings taken can be adjusted by manually adjusting the amount of seedlings taken through a manual adjustment button for the amount of seedlings taken connected to the vehicle controller, thereby controlling the planting claws to rise or fall, thereby achieving adjustment of the amount of seedlings taken.

[0066] The technical solution of this embodiment can accurately adjust the amount of seedlings to be taken according to different seedling density areas, avoid the problem of missed seedlings or uneven transplanting due to individual differences in seedlings, reduce the tedious operations of manual inspection and manual seedling replenishment, improve the efficiency and quality of transplanting, and thus improve the yield and quality of crops such as rice. It has a positive promoting effect on agricultural production, enhances the adaptability and intelligence level of the rice transplanter, and ensures the benefits of agricultural production.
