智能烟草打顶抑芽机控制系统

为实现烟草打顶抑芽同步进行以及对烟草高度的精确仿形，改善人工打顶抑芽及“一刀切”打顶的状况，研制了智能烟草打顶抑芽机，烟草打顶和抑芽剂精量喷施同步进行，其控制系统中的烟草智能打顶系统由15个红外光电传感器对烟草高度精确仿形，由单片机系统对步进电机的转动方向和转角的大小进行控制，步进电机带动刀架提升或降低，在烟草合适的高度实现烟草打顶；抑芽剂喷施系统由红外光电传感器对烟草进行检测，当检测到烟草时就喷施不少于 15 mL的抑芽剂，反之就不会喷施抑芽剂，从而实现了抑芽剂的准时精量喷施。试验结果表明：烟草高度识别系统识别精度达到98%，抑芽剂喷施系统给每棵烟草的抑芽剂喷施量达到15 mL以上，控制系统能实现烟草打顶高度的精确控制以及打顶后抑芽剂的准时精量喷施。

Control system of intelligentized tobacco topping and sucker controlling machine

In order to realize topping and restrain-germinating simultaneously and precise profiling of tobacco height,an intelligentized tobacco topping and sucker controlling machine was developed to improve the situation of manual topping and bud inhibition and the technology of tobacco topping that non-discretionary implementation.Fifteen infrared photoelectric sensors in the system were used for profiling of tobacco height.Microcontroller unit was used for controlling rotation direction and rotation angle of step...
