针对传统农药喷洒时人工一次性将农药混合后喷洒存在易发生人员中毒、混合比例精度差、长时间喷洒药效降低、农药浪费的问题,以单片机技术为核心,结合传感器、遥控技术,设计一种具有参数设定、药液流量实时采集显示、调节及药液实时混合等功能的控制系统。经试验,该系统工作可靠、控制精度高、成本低廉,能够根据农作物施药需求实时、按比例进行农药混合,能够降低人员中毒风险、提高药效,具有较好的应用价值。
Aiming at the problems of traditional one-time pesticide spraying, such as pesticide spraying, pesticide poisoning, poor mixing ratio accuracy, long time spraying efficacy and waste of pesticides, the single-chip microcomputer technology is the core of this traditional pesticide spraying process. In combination with sensors and remote control technology, With the parameters set, liquid flow real-time acquisition display, real-time mixing and other functions of liquid medicine control system. According to the experiment, the system is reliable, the control precision is high and the cost is low. It can mix pesticides in real time and proportion according to the demand of crop application, reduce the risk of personnel poisoning, improve the efficacy and have better application value.
