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.
