Abstract
Provided are a pipeline spanning or settlement bending detection device and method, relating to the field of pipeline curvature measurement technology, to solve the problem that the curvature of a pipeline made of a composite material cannot be detected using the related art. The device includes a watertight spherical shell and multiple detectors. For each detector, the detector is configured to acquire a non-magnetic signal fed back by the inner wall of a to-be-detected pipeline to determine the distance between the detector and the inner wall of the pipeline. The method includes that a microcontroller acquires a two-axis accelerometer signal and calculates pipeline curvature when non-magnetic signals reach the extremum.
