Missing potato seeding and missing seeding supplementing control system

Abstract

The invention discloses a missing potato seeding and missing seeding supplementing control system. An infrared missing seeding detection system circuit comprises an infrared transmitting circuit, an infrared receiving circuit and an infrared receiving power control circuit; a controller controls the infrared transmitting circuit to transmit an infrared signal to the infrared receiving circuit, the infrared receiving circuit is controlled via the infrared receiving power control circuit to transmit the signal to a controller, a missing seeding detection startup signal generating circuit comprises a missing seeding detection startup level conversion circuit connected with the controller, a reed relay for controlling the missing seeding detection startup level conversion circuit to operate, and a permanent magnet for controlling the reed relay to operate; the invention aims to provide the missing potato seeding and missing seeding supplementing control system that has better controlled operating time and effectively improved anti-interference capacity, ensuring signal accuracy and seed supplement success rate and effectively reducing a misjudgment likelihood.

Description

technical field [0001] The invention belongs to the technical field of agricultural electric automation control for missed sowing detection and replanting of a potato planter, and in particular relates to a potato missed sowing detection and missed sowing reseeding control system. Background technique [0002] With the continuous improvement of the mechanization of potato planting in our country, the problem of yield reduction caused by missed sowing cannot be avoided. The effective measure to solve the problem of missed sowing is to increase the monitoring of missed sowing and compensation devices for missed sowing. In potato planting, planting of diced potatoes is the main method , its seed picking mechanism and seeding method are very different from those of wheat, corn, soybeans, etc. In fact, due to the large tubers of potato seeds and the large sowing distance, even if a single seed is missed, the impact is quite obvious. Therefore, every missed sowing must be reliably...

AI Technical Summary

Problems solved by technology

In the prior art, there is an electromechanical potato seeder automatic compensation scheme composed of infrared photoelectric sensor, controller, and stepping motor. However, its leakage detection scheme is relatively primitive and has poor reliability. The replanting scheme of the replanting device is complex in structure, slow in speed, and poor in practicability; another kind of potato missing seeding compensation based on the ATmegal6 controller infrared missed seeding detection system and the crank connecting rod striking replanting mechanism in the prior art program, the system has high integration, fast replanting speed, and high application value, but the design of the circuit hardware and control system of the whole program is not comprehensive, and the engineering practicability of the program needs to be improved.
