Design and Experiment of a Situ Compensation System for Miss-Seeding of Spoon-Chain Potato Seeders

Highlights A situ compensation system for miss-seeding of spoon-chain potato seeders was designed. Human/computer interaction system for visual quality monitoring of spoon chain potato planting. The miss-seeding problem of spoon-chain potato seeder was improved. Design of miss-seeding compensation device for spoon chain potato seeder. Abstract. To address the problem of miss-seeding in spoon chain potato seeders, a set of in situ compensation systems for miss-seeding of spoon chain potato based on compensation technology was designed. The system consists of three parts: a miss-seeding detection system, a miss-seeding compensation system, and a visual monitoring system that can realize real-time feedback and reseeding of miss-seeding. The actual seeding situation of the compensated potato will be visually monitored by the industrial camera, and the seeding count will be conducted. The real-time seeding screen is displayed on the upper computer. The design of miss-seeding detection device, in situ reseeding device, structure design of miss-seeding in situ compensation system based on PLC visual monitoring human-computer interaction system were carried out. Then the potato miss-seeding compensation bench test and field test were carried out. Field experiments showed that when the seeding rate of the potato seeder was 0.3 to 0.7 m/s, the detection accuracy of the miss-seeding detection system could reach more than 98.5%, and the miss-seeding rates after reseeding were all below 5%. The visual monitoring effect of seeding quality was good, and the counting accuracy was 99.5%. The designed in situ compensation system has stable working state, light structure, high compensation and monitoring accuracy, and can solve the problem of miss-seeding in the operation of spoon and chain potato seeders.
