摘　　要：利用计算机模式识别原理,快速、准确地识别出抽油杆表面多种缺陷的阻抗图.研制出RODECI-CRS软件系统,用计算机代替人工识别,实现了抽油杆涡流检测生产线的自动化.Based on the principle of model recognition, we can quickly and accurately identify the impedance charts of various defects on the surface of pump-rod. RODECI-CRS software has been developed for automatic i-dentification instead of artificial one.Thus, the automation of eddy current on-line inspection of pump-rods has been realized.
