Title : Design and experimentation of an intelligent control system for a small self-propelled electric transplanter

Abstract :

The purpose of this paper is to design an intelligent electric transplanter to improve the efficiency of greenhouse vegetable transplanting and the accuracy of precise plant spacing.kernel technologies of the transplanter include mechanical design, adaptive fuzzy PID control, and Android terminal control. The main body of the mechanical part is composed of the seeding cups and the hanging cup type planetary wheel planting mechanism. An adaptive fuzzy PID algorithm is proposed to accurately control the rotating speed of the driving motor and the working motor, and simultaneously, the driving device and the planting device are perfectly matched. In experiments with transplanting frequency of 30-40 plants per minute, transplanted seedlings spaced 30-40 cm apart, and a controlled rate of 40 plants per minute, it was found that the maximum and average control errors of the transplanter's motor speed are respectively 12.76% and 10.83% if the motor speeds are between 20-40 rpm. When compared with a conventional PID controller, the adaptive fuzzy PID controller can reduce the maximum and average control errors by 6.8% and 6.25%, respectively. Moreover, the average error rate of planting spacing, the maximum error rate of line spacing, and the success rate of transplanting are respectively 6.21%, 13.37%, and 95.67%. the control software of the mobile phone is utilized to conduct state detection and transmission to the cloud. The position of the transplanter can be monitored online and the travel speed, transplanting speed and transplanting spacing of the transplanter can be adjusted in real time.
