海底管道内检测器实时跟踪与精确定位

A Method of Tracking and Precisely Locating Submarine In-line Inspection Tool

针对海底管道检测中内检测器的位置确定问题,提出实时跟踪与精确定位方法。该方法联合应用压力波和超低频电磁波方法,通过压力波对内检测器实时跟踪,而利用超低频电磁波对内检测器进行精确定位,从而可有效解决海底管道内检测器的跟踪定位问题。根据所提出的方法,给出了实时跟踪与精确定位系统的整体结构的设计思路。通过仿真验证,证明该方法的有效性,对海底管道安全内检测具有重要的实际应用价值。

Aiming to determine the position of pipeline internal detector when pipeline internal detection technology being applied in submarine pipeline, a new method of tracking and precisely locating pipeline internal detector is proposed in this paper to locate the detector, which is verified to be feasible according to the simulation with （）LGA software. In addition, the whole structure of tracking and precisely locating system that has great significance and practical value is given in this paper.
