Embodiment Construction

[0014] see Figure 1-2 , the embodiment of the present invention provides a method for measuring parameters of a pipeline elbow direction for an in-pipeline detector, which includes using a gyroscope sensor and an acceleration sensor in the intelligent detection of buried long-distance pipelines to obtain information about the pipeline elbow; The movement in the pipe elbow, the gyro sensor and the acceleration sensor are set on the detector 1, connected with the detector 1, and the motion signal is transmitted to the gyro sensor and the acceleration sensor; the acceleration sensor determines the detector by measuring the acceleration of gravity 1 Space attitude in the pipeline; the output of the gyroscope sensor is the angular velocity change rate ω when the inner detector rotates along different coordinate axes during the travel process x , ω y , ω z ;The adopted gyroscope sensor and acceleration sensor are respectively installed on three mutually perpendicular planes compo...

Abstract

The invention discloses a pipeline elbow trend parameter measurement method for detectors in a pipeline, and belongs to the technical field of non-destructive testing. The pipeline elbow trend parameter measurement method comprises the following methods; obtaining pipeline elbow information by applying a gyroscope sensor and an acceleration sensor in intelligent testing of a buried long-distance pipeline, wherein the gyroscope sensor and the acceleration sensor are respectively arranged on three planes which are formed by x, y and z coordinate axles and perpendicular to one another; outputting angular speed change rate and acceleration information in the directions of the x axis which is the advancing direction of the pipeline medium, the y axis which is perpendicular to the direction of the pipeline and horizontally leftward and the z axis which is perpendicular to the xy plane and upward; computing according to the angular speed change rate and the acceleration information to obtain the curvature radii of the pipeline elbows, the elbow angles and the elbow deflecting direction information. The pipeline elbow trend parameter measurement method is capable of providing related reference basis for the integrity management of pipelines without increasing the testing cost.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a method for measuring parameters of a pipeline elbow direction for an in-pipeline detector. Background technique [0002] During the long-term operation of long-distance pipelines, due to changes in local geological structures, the pipeline bends and the radius of curvature of the original elbows on the pipeline changes, resulting in local stress and hidden dangers to the safe operation of the pipeline. In order to improve the missing data of pipelines, obtain detailed pipeline elbow information, and provide reference for future pipeline integrity management, obtaining pipeline elbow direction information has become a basic requirement for intelligent detection of in-service pipelines. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for measuring parameters of pipeline elbows used by in-pipel...
