摘　　要：随着时代的进步,普通单一性能产品无法满足现代工业生产需求。在这个发展的过程中,工业上经常要多样性地应用设备监测旋转轴的转向和转速。因此旋转轴的转向和转速检测电路的可靠性与检测结果的准确性就显得尤为重要。文章利用西门子PLC(S7-200)和变频器MM440实现对旋转齿轮的转向和转速检测,为工作中经常遇到的发电机转速、锚机锚缆长度、吊机旋转等问题提供有效的试验数据。With the progress of the times,ordinary single performance products cannot meet the needs of modern industrial production.In this development process,diverse application equipment is often needed in industry to monitor the rotation direction and speed of the rotating shaft.Therefore,the reliability of the rotation direction and speed detection circuit of the rotating shaft,as well as the accuracy of the detection results,are particularly important.The article utilizes Siemens PLC(S7-200)and frequency converter MM440 to achieve steering and speed detection of rotating gears,providing effective experimental data for common problems encountered in work such as generator speed,anchor cable length,and crane rotation.
