Gas pipeline checking method and device

Abstract

The invention provides a gas pipeline checking method and device. The gas pipeline checking method comprises the following steps of obtaining a pipe section set needing pipeline checking; judging whether a pipe section forming a loop exists in the pipe section set or not, whether a spanned pipe section exists or not and whether a sharp bend pipe section exists or not; recording the pipe section forming the loop, the spanned pipe section and the sharp bend pipe section as suspicious pipe sections; and displaying the suspicious pipe section in a map so as to judge whether the suspicious pipe section has a wrong trend or not. According to the invention, the trend of the gas pipeline can be conveniently and effectively verified.

Description

technical field [0001] The invention relates to the technical field of gas pipeline detection, in particular to a gas pipeline calibration method and a gas pipeline calibration device. Background technique [0002] Gas, as a clean energy, is environmentally friendly, safe, reliable, and economical to a certain extent. As the application range of gas becomes wider and wider, more and more gas pipelines are buried, and the arrangement of gas pipelines in many areas is relatively dense and complicated. Therefore, when pipeline construction personnel use RTK to survey and map urban gas pipelines, they often cause errors in the direction of pipelines due to equipment drift or personnel errors. How to check whether the pipeline direction is wrong has become a problem that needs to be solved urgently. Contents of the invention [0003] In order to solve the technical problem of how to check whether the direction of the pipeline is wrong, the present invention provides a method ...
