摘要/Abstract

摘要： 介绍一种适于非开挖地下管道的三维形状探测系统，该系统主要由以重力加速度计、磁强计、定心机构组成的传感头、计程机构、控制电路及上位机控制系统组成.传感头在管道内拖动过程中，在每个采样点处通过传感器采集该采样点处的方向角信息，然后结合计程机构所获得的采样点间的间距，可以得到管道相应位置的三维坐标及管道轴线的空间形状.该管道探测系统在管道位置深度的重复测量精度可达到±5%.

Abstract: A system for detecting the 3D shape of underground pipelines, especially in trenchless construction process, has been developed. This pipeline detecting system is composed of a gravity accelerometer, a magnetometer, a distance measuring mechanism and a control circuit. Driven in the pipe, the sensors measure the direction angle and distance at certain points. The 3D coordinates and the shape of the pipe are then obtained. Measurement repetitiveness of the pipe position is within ±5%.

Key words: gravity accelerometer, magnetometer, pipeline detecting system, trenchless
