摘　　要：在生产线上对钢缆绳长度进行实时准确的测量,其关键是检测打滑,消除由于打滑带来的测量误差。在对生产流程分析的基础上,采用成品卷筒和主动卷筒的转速比在短时间内是否有跳变的方法来检测是否打滑,从而消除由于打滑而引起的测量误差。用编码器零位来消除由于现场干扰而引入的少量非计数脉冲。实验结果表明,该系统工作可靠,测量误差小于0.2%。In measuring the steel wire rope, the key problem is to detect and eliminate the measure error for wheel spin. In order to measure the length of steel wire rope precisely, the velocity ratio of the wheel of steel wire rope and driving windlass is adopted for detecting wheel spin and the accumulated pulse error is also adopted to eliminate the round off error. Phase zero is used to remove the jam pulse of electromagnetism. The result shows the system works reliably and the measure error is less than 0.2%.
