摘　　要：研究实现了一种农用推杆电机的低成本行程控制算法。该算法基于霍尔计数原理,通过给普通农用推杆电机加装2个霍尔传感器使得电机运行时输出2路方波信号来实现。电机运行时每转一圈会触发霍尔传感器输出一个脉冲信号,2路信号具有90°的相位差,通过2路信号的相位关系可判断出电机的正反转状态并据此对脉冲信号进行加数计数或减数计数,算法根据用户设置的行程百分比、霍尔计数值以及全行程霍尔计数总值实现电机行程的自动控制。该算法具有行程控制稳定可靠、实现成本低、适用于农业高湿多尘环境等优点,可应用于设施农业和大田农业中相关设备的现场自动控制以及基于农业物联网的远程精准控制。A low-cost stroke control algorithm for agricultural push rod motor was studied and implemented.This algorithm is based on the Hall counting principle,which is achieved by adding two Hall sensors to the ordinary agricultural push rod motor to output two square wave signals during motor operation.During the operation of the motor,each revolution will trigger the Hall sensor to output a pulse signal.The two signals have a phase difference of 90°.The forward and reverse states of the motor can be judged by the phase relationship of the two signals,and the pulse signal can be added or subtracted based on this.The algorithm realizes the automatic control of motor stroke according to the user set stroke percentage,Hall count value,and total stroke Hall count value.This algorithm has the advantages of stable and reliable stroke control,low cost,and suitability for high humidity and dust environments in agriculture.It can be applied to on-site automatic control of related equipment in facility agriculture and field agriculture,as well as remote precise control based on Agricultural Internet of Things.
