摘　　要：为完全解除电涡流导向孔的半封闭状态,设计基于主元分析方法的智能导向孔偏心距检测系统。利用电涡流传感器,确定超声发射接收放大电路、压控增益模块间的真实物理距离,完成新型检测系统的硬件运行环境搭建。通过提取压缩电量数据信息的方式,计算主元分析偏心量的数值化水平,再按照自适应检测控限原理,完成新型检测系统的软件运行环境搭建,联合相关硬件执行设备,实现基于主元分析方法智能导向孔偏心距检测系统的顺利应用。对比实验结果表明,与EWMA滤波系统相比,应用新型检测系统后,深孔中心偏斜差量明显降低,偏心距探伤准度由60%提升至83%,完全打破电涡流导向孔的半封闭传输状态。In order to completely remove the semi⁃closed state of the eddy current orifice,an intelligent orifice eccentricity detection system based on principal component analysis is designed.By using eddy current sensor,the real physical distance between ultrasonic transmitting and receiving amplifier circuit and voltage control gain module is determined,and the hardware operation environment of the new detection system is built.By extracting the compressed data information,the calculation of the principal component analysis of eccentricity value level,and then according to the principle of adaptive control limits,to complete new software running environment of the detection system,joint relevant hardware equipment,the implementation is based on principal component analysis method of intelligent guide hole eccentricity detection system applied smoothly.The experimental results show that,compared with the EWMA filter system,the center deflection difference of the deep hole is significantly reduced after the new detection system is applied,and the flaw detection accuracy of the eccentricity is increased from 60%to 83%,completely breaking the semi⁃closed transmission state of the eddy current guide hole.
