Problems solved by technology

At the same time, the quality of the sowing results of the breeding plot will directly affect the implementation and effect of the new variety detection in the breeding plot, which will cause unnecessary impact on the selection of new varieties, and the selection of good traits will not be possible.
At present, most of the sowing work in the experimental fields of breeding plots is done manually or by machinery with a low ...

Example Embodiment

[0011] The plot seeding device includes the rack 4, and also includes a control platform 12 and an image acquisition system and a delivery system set on the rack 4; the image acquisition system includes a dark box 3 and a photoelectric switch 13, and a dark box 3 set on the rack 4. The lighting device 2 and the image acquisition device 1 are arranged inside; the delivery system includes the seeding claw 11 and the seeding claw driving mechanism; the seeding claw driving mechanism includes the mechanical arm I5, the mechanical arm II6 and the mechanical arm III8, and the mechanical arm I5 is set on the frame 4. , The mechanical arm II6 and the mechanical arm III8 are connected by a steering gear I7, the mechanical arm III8 and the seeding claw 11 are connected by a steering gear II9, and the seeding claw 11 is controlled by the seeding claw steering gear 10 for picking and placing operations.
[0012] The control platform 12 includes a power supply system, a main controller, an auxiliary controller and a display system; the auxiliary controller is connected to the image acquisition device 1 and the photoelectric switch 14, and the main controller is respectively connected to the steering gear I7, steering gear II9 and seeding through dial switches. The claw steering gear 10 is connected. The auxiliary controller is connected with the main controller for data transmission.
[0013] The power supply system on the control platform 12 includes a power distribution controller, the power distribution controller is connected to a plurality of independent power supply modules, and the plurality of independent power supply modules supply power to the main controller, the auxiliary controller and the seeding claw drive mechanism respectively. This kind of power supply mode can reduce the influence between various power supply units and reduce fluctuations.
[0014] The image acquisition device 1 takes photos and samples of the road signs of the seeding area, transmits the photographed images to the auxiliary controller for binarization processing, and stores the processing results in the auxiliary controller. The photoelectric switch 13 emits a beam of light when it is working. When the light is reflected or blocked, the internal synchronization loop gates the circuit to detect whether there is an object in the linear distance of the photoelectric switch. Otherwise, there is no object. Detected. Anything that can reflect light can be detected. The optical signal is obtained by converting the input current on the transmitter of the photoelectric switch. The receiver uses the intensity or presence of the received light as the criterion for judging, and the receiver feeds the signal to the auxiliary controller as the criterion for road conditions. .
[0015] When planting in the cell, the image acquisition device 1 scans the fragmentation information of the cell, and the photoelectric switch 13 scans the road condition information of the cell and feeds the information back to the auxiliary controller. The auxiliary controller queries and processes the information received by the image acquisition device 1 , Identify the sowing cell division information. The feedback information of the photoelectric switch 13 is processed as a criterion for judging road condition information. The auxiliary controller feeds back the recognition result to the main controller, and the main controller sends a drive signal to the seeding pawl driving mechanism to control the seeding pawl 11 to complete the operations of seeding and seeding. The driving signals of the steering gear I7, the steering gear II9 and the seeding claw steering gear 10 are the PWM signals from the main controller. The display unit on the control platform 12 is connected to the main controller and displays the PWM signal given by the main controller, which is convenient for debugging the steering gear I7, the steering gear II9 and the seeding claw steering gear 10. The DIP switch is mainly used to provide high and low levels for PWM to determine the position of the servo during the debugging process of the steering gear I7, the steering gear II9 and the seeding claw steering gear 10.
[0016] After planting one line, scan and plant the next line automatically.
