摘要
针对果园作物生长环境复杂、农药利用率低且易流失造成环境污染问题,设计了果园自动对靶施药系统。该系统采用红外光电传感器探测果树,根据传感器信号控制电磁阀状态实现自动对靶施药;采用红外测距传感器实时检测周围环境,实现避障及转弯。室内模型实验表明:该系统能够自主行走、垄间穿行、果树识别和向果树对靶施药,小车行走速度约0.5 m/s时对靶喷药时间约20 ms。该研究为在果园中实施自动对靶施药技术提供了理论依据。
Orchard crop growth environment is complex.Pesticide utilization is low and easy to cause environmental pollution.Based on this,the orchard automatic spraying system is designed.Infrared photoelectric sensors are used to detect fruit trees.The solenoid valve is controlled according to the sensor signal.Infrared distance sensor is used to detect the surrounding environment,to achieve barrier and turn.Through the indoor model experiment,the system can walk autonomously,ridge through the line,fruit tree identification and fruit to the target application.The time to spray the target is20 ms when the car walking speed of 0.5 m/s.This study provides a theoretical and practical basis for the implementation of automatic target application technology in orchards.
