摘　　要：针对目前烟草抑芽剂施用现状,设计了烟草抑芽剂智能对靶施药系统,该系统主要由支架、测速传感器、烟秆检测传感器、步进电机、卷轴、电磁阀、滑块、滑轨、单向阀、喷管、行程开关、单片机系统等组成。测速传感器可对机组的作业速度实时检测,单片机系统根据检测的机组作业速度控制步进电机的转速、根据电磁阀开启时间控制步进电机的转角,并根据烟草茎秆信号的有无控制电磁阀开闭,实现了烟草抑芽剂的智能对靶施药。对烟草抑芽剂智能对靶施药系统进行了室内试验,结果显示:试验台运动速度越慢(0.3～0.45m/s),收集药量Qs≥15mL的比例越高,施药效果愈好;随着药泵压力的升高,收集药量呈缓慢下降趋势。样机田间试验结果表明:设计的烟草抑芽剂智能对靶施药系统工作准确可靠,满足使用要求。According to the fact that the current application state of tobacco pesticide of restrain-germinatin, intelligent spraying system on target was designed, which consists of bracket, speed sensor, tobacco stalk sensor, stepping motor, reel, electromagnetic valve, the slider, slippery course, one-way valve, nozzle, travel switch and SCM system, etc. Speed sensor can carry out real-time detection in response to the working speed of the unit, and SCM system controls the rotation speed and angle of stepping motor according to the detected unit working speed and magnetic valve starting time respectively. And SCM system also controls the magnetic valve opening and closing according to the presence or absence of the tobacco stalk signals. Indoor test showed the more slowly the test station moves（within 0.3-0.45 rn/s ）, the greater pesticide quantity （Qs〉15 ml）and the better pesticide effect. With the rise of pesticide pump pressure, pesticide collection will reduce slowly. The test result of model machine indicated intelligent aiming spraying system of tobacco pesticide of restrain-germinatin can work accurately and reliably and satisfy the application requirements.
