摘要
本文针对管道智能检测球在管道内定位精度低、累计误差大的问题,提出了一种基于内外联合定位的新方法.首先,通过利用外部磁力标签修正和校准球体的位置信息,改善定位精度.其次,提出了 4种基于惯性传感器的定位方法,并结合内外联合定位技术,实现了分段定位和误差补偿.这一研究为管道智能检测技术的发展提供了新的思路和方法,对提高管道安全性具有重要意义.通过该方法,可以有效解决传统管道检测中定位不准确和误差累积问题,提高管道检测的准确性和可靠性.
Abstract
This paper proposes a new method based on internal and external joint positioning to solve the problems of low positioning accuracy and large cumulative error of intelligent pipeline detection balls in pipelines.Firstly,positioning accuracy is improved by correcting and calibrating the sphere's position information using external magnetic tags.Secondly,four positioning methods based on inertial sensors are proposed,combined with internal and external joint positioning technology,to achieve segmented positioning and error compensation.This research provides new ideas and methods for the development of intelligent pipeline detection technology,and is of great significance to improving pipeline safety.Through this method,the problems of inaccurate positioning and error accumulation in traditional pipeline detection can be effectively solved,and the accuracy and reliability of pipeline detection can be improved.
