摘　　要：危化品储罐的广泛应用与安全运行对底板的可靠性检测提出了更高要求。对于储罐底板可靠性检测,由于罐内承载介质有毒有害,且内部采光条件十分恶劣,而传统的漏磁检测的检测效率、检测定位的准确性、路径规划等方面的研究还不能满足实际应用的需求,易使检测人员时常出现漏检或误判现象。提出通过辅助定位技术提高储罐底板漏磁智能检测的定位精确度和检测覆盖率。通过分析定位桩的直径、高度、材质和放置方式等对定位性能指标的影响,发现采用悬挂式摆放?0.05 m×H0.5 m完全不透明材质的圆柱形PVC管作为定位桩,其距离和角度数据更准确,能够使漏磁检测设备在储罐内精确定位、检测全覆盖并自动检测,具有路径偏移纠正功能,提高检测效率,降低劳动强度,为实现漏磁智能检测提供了解决方案。The wide application and safe operation of hazardous chemicals storage tanks put forward higher requirements for the reliability detection of the bottom plate. For the reliability test of the tank bottom plate, because the bearing medium in the tank is toxic and harmful, and the internal lighting conditions are very bad, while the traditional research on the efficiency of magnetic flux leakage detection, the accuracy of detection and location, path planning and other aspects can not meet the needs of practical application, which is prone to make the detection personnel often fail to detect or misjudge. The auxiliary positioning technology was proposed to improve the positioning accuracy and detection coverage of intelligent magnetic flux leakage detection of tank floor. By analyzing the influence of the diameter, height, material and placement method of the positioning pile on the positioning performance index. It is found that hanging placement of the cylindrical PVC pipe with the diameter of 0.05 m × height of 0.5 m and completely opaque material is used as the positioning pile,its distance and angle data are more accurate, which can make the magnetic flux leakage detection equipment accurately locate in the storage tank, detect full coverage and automatically detect. It has the function of path offset correction, improve the detection efficiency and reduce the labor intensity. It provides a solution for realizing the intelligent detection of magnetic flux leakage.
