摘　　要：为了实现三跨圆形喷灌机电机精准同步并达到提高灌水均匀度的控制目的,本系统使用变频器配合主行走电机进行了同步控制,并使用可编程逻辑控制器及人机界面,设计了圆形喷灌机的监控组态系统,同时具有手动控制功能。该系统能够显著提高喷灌作业时的灌水均匀度,有利于作物生长,提高农业生产效率。In order to realize the accurate synchronization across three circular sprinkler motor and reach the control goal of improving irrigation uniformity, the control system of center pivot irrigation machine was designed by using frequency converter to control the main motor and using programmable logic controller and human-machine interface. It also has manual control function. The system can significantly improve the irrigation uniformity during irrigation, which is beneficial to the efficiency of crop growth and agricultural production.
