摘　　要：针对现有电驱动卷盘喷灌机无法实现作业信息无线物联和控制的问题,设计了一种基于手机APP的卷盘式喷灌机无刷直流电动机驱动与控制系统.以直流电动机代替机械式水涡轮作为卷盘喷灌机的驱动装置,分析并建立了卷盘喷灌机现场作业工况模型;采用STM32作为系统控制器,引入了增量式PID电动机调速,设计了可以远程监控卷盘喷灌机作业的手机客户端,系统完成自动校正.经过试验测试表明,驱动电动机可以稳定在设定转速上,在10%的负载扰动下转速可以较快回到设定值,手机客户端可以远程监控卷盘喷灌机的运行剩余时间、PE管长度电动机转速、卷盘转速和PE管回收速度等作业信息,为实现喷灌机智慧灌溉提供了前台保障.Aiming at the problem that the existing electric drive reel irrigation machine can not achieve the wireless connection and control of operation information, a brushless direct-current（DC）motor drive and control system based on mobile APP were designed. To replace the mechanical type water turbine DC motor as driving device of reel sprinkling machine, reel sprinkling machine field operation model was analyzed and built. Using STM32 as a system controller, introducing the incremental PID motor, mobile phone client and to remotely monitor the reel sprinkling machine industry were designed, completed the automatic correction system. Through experiments, the drive motor can be stable at a set speed, can be quickly returned to the set value in 10% the disturbance of load speed. The mobile phone client can run the remaining time, remote monitoring the residual time of the reel sprinkling machine, PE pipe length motor speed, reel speed and recovery rate of PE pipe, which provides the guarantee for the realization of sprinkler irrigation wisdom.
