摘　　要：为了实现秸秆的综合利用,降低秸秆燃烧对环境的污染,首先需要对秸秆进行切割操作。秸秆的切割力是影响切割装置机械效率的主要因素,因此对切割装置优化设计时需要得到农作物秸秆切割过程使用的最佳切割力。为此,设计了一种新的秸秆切割力的控制系统。该系统采用PLC嵌入式系统对刀片传感器的数据进行采集,采用Dijkstra算法对数据进行处理,将处理结果作为电机控制的条件,调控切割力,并通过反馈调节来控制电机转速,从而降低功耗,提高切割效率。为了验证该系统的有效性和可靠性,通过实验的方式对切割系统进行了测试。测试结果明明:该系统的功耗低,切割时间短,大大提高了农作物秸秆的切割效率,为农作物秸秆的综合利用和生态农业的发展提供了技术支持。In order to realize the comprehensive utilization of straw straw burning,reduce pollution to the environment,first of all need to cut the operation of straw,straw cutting force is the main factor affecting the cutting device of mechanical efficiency,so the optimization of the design of cutting device needs to be crop straw cutting process using the best cutting force. Puts forward a new control system of straw cutting force,the system adopts data acquisition of blade sensor of PLC embedded system,Dijkstra algorithm is used to process the data,the processing result as the motor control conditions,regulation and control of cutting force,and through the feedback to control the speed of the motor,thereby reducing power consumption,improving the cutting efficiency. In order to verify the effectiveness of the system and the reliability,by the way of experiments on cutting system was tested,found by testing,power consumption of the system is low,cutting short time,greatly improving the cutting efficiency of crop straw,in order to develop comprehensive utilization of crop straw and ecological agriculture provides technical support.
