Positioning device and positioning system for in-pipeline detection device

Abstract

The invention relates to the field of pipeline detection, and provides a positioning device for an in-pipeline detection device. The positioning device comprises an induction signal detection module, a timer, and an induction signal processing module, wherein the induction signal detection module is used for detecting induction signals from the in-pipeline detection device; and the induction signal processing module is connected with the induction signal detection module and the timer respectively, and is used for determining and recording the position of the in-pipeline detection device in a pipeline and the time when the in-pipeline detection device passes through the position according to a detection result of the induction signal detection module and timing information of the timer. The invention also provides a positioning system for the in-pipeline detection device, which comprises an induction signal transmitter, and the positioning device, wherein the induction signal transmitter is arranged on the in-pipeline detection device and is used for transmitting induction signals. The positioning device and the positioning system can obtain the traveling condition of the in-pipeline detection device in the pipeline in time.

Description

technical field [0001] The invention relates to the field of pipeline detection, and more specifically, relates to a positioning device for positioning a detection device in a pipeline and a positioning system including the positioning device. Background technique [0002] As we all know, pipeline transportation is the main transportation method of oil or natural gas. Also, in order to transport oil or gas to the desired area, it is often necessary to lay pipelines over long distances. [0003] With the growth of service time, various defects will inevitably appear in long-distance steel pipes, for example, due to electrochemical reactions, the inner wall of the pipe may be corroded, resulting in pits or cracks; It may cause deformation of the pipe, etc. If remedial measures are not taken in time for the defects that have occurred, it is easy to cause accidents in the pipeline and cause huge losses. Therefore, it is of great significance to regularly inspect the pipeline ...
