Embodiment 1

[0039] Embodiment 1. This embodiment proposes a missing-seeding detection-reseeding system, which is suitable for sowing large-sized crops such as peanuts and potatoes, and is suitable for the improvement and utilization of spoon chain or disc seeders. refer to figure 1 , which is a block diagram of the system, including the intelligent controller and the missed-seeding detection sensor connected to it, the Hall sensor, the encoding speed sensor and the seeding DC motor. Accurate detection of the position, the coded speed sensor is installed above the coaxial gear with the bottom wheel (the distance between the two is 3mm-5mm) to form the key component of stroke perception, which is used to detect the speed of the traction bottom wheel. The controllers are connected to each other to drive the scoop chain of the seeder to run independently, and directly drive the scoop chain to rotate through the seeding DC motor to realize the intelligent control of uniform distribution of pla...

Embodiment 3

[0049] Embodiment 3, present embodiment is based on the control system proposed in embodiment 2, proposes a kind of potato miss-seeding detection-replanting method, comprises the following steps:

[0050] A. System initialization, set planting spacing;

[0051] B. When the encoding speed sensor detects that the bottom wheel starts to run, the intelligent controller controls the drive module to drive the seeding DC motor to run according to the set distance between plants to sow seeds;

[0052] C. Leaked sowing detection: During the sowing process, the Hall sensor, photoelectric sensor and piezoelectric sensor jointly detect to determine whether the current seed picking spoon is short of seeds;

[0053] When the Hall sensor is aligned with the position of the seed picking spoon, the signal acquisition of the photoelectric sensor and the piezoelectric sensor is carried out;

[0054] If there is no signal from the photoelectric sensor, it means that the current seed picking spoo...

Abstract

The invention proposes a seeding leakage detection-reseeding system and a potato seeding leakage detection-reseeding integrated control system and method. The system is independent of an original seeding mode that a return pulley drives a seeder to carry out seeding, and employs an independent seed arrangement DC motor to drive a spoon chain to operate. The seed arrangement DC motor is connected with an intelligent controller, and the speed of the return pulley is detected in real time through a coding speed sensor. The intelligent controller carries out the precise detection of a seeding leakage position through receiving the signals of photoelectric, piezoelectric and Hall sensors which are installed on side surfaces of a seed spoon, and carries out the precise judgment of the reseedingmoment in a counting mode. During reseeding, the system employs a mode of crossing a spoon without seeds to employ a next spoon with seeds for reseeding through acceleration control, so the mode is novel, and the system is high in precision of seeding leakage detection and reseeding. Moreover, the seed arrangement DC motor is used for independently controlling the seed spoon to rotate, thereby achieving the variable-speed adjustable seed arrangement and reseeding control of the independent constraint control of potato seeding, and achieving the integrated control of the seeding leakage detection and reseeding.

Description

technical field [0001] The invention relates to the field of automatic control of agricultural engineering, in particular to a missed-seeding detection-replanting system, a potato missed-seeding detection-replanting integrated control system and a method thereof. Background technique [0002] The spoon chain seed meter is a kind of seeder commonly used by small and medium-sized potato seeders at present. It has the advantages of high reliability, adjustable plant spacing, and can meet the requirements of different sowing spacing. However, the existing seeders are all driven by a tractor to drive the bottom wheel, and the bottom wheel is mechanically driven by a chain to sow seeds, and the plant-to-plant distance adjustment is realized by manually adjusting the speed gear ratio, and the plant-to-plant distance cannot be adjusted with the speed of the tractor. It is more troublesome; in addition, due to the different sizes and shapes of the seed potato pieces, it is difficult ...
