Underground gas pipeline detecting and positioning system

Abstract

The invention belongs to the field of underground gas pipeline detection and positioning, and particularly relates to an underground gas pipeline detection and positioning system which is combined with an existing electronic map, draws an underground gas pipeline diagram in a live-action map, enables the underground gas pipeline diagram to be combined with a real scene, and combines the live-action map with a CAD diagram of an underground pipeline. A corresponding CAD drawing can be quickly checked, the time for a maintainer to search the position of the pipeline is shortened, the time for the maintainer to see the drawing is shortened, the speed for the maintainer to judge the position of a gas leakage point is increased, and therefore the danger caused by gas leakage of the pipeline is reduced; the gas pipeline in the underground pipe gallery is detected in real time through the detection unit, the preprocessing unit and the alarm unit, when gas leakage points appear in the pipe gallery, accurate and rapid positioning can be achieved, the alarm unit and the preprocessing unit are both of a grading system, different alarm information is provided for different gas leakage conditions, different preprocessing measures are adopted, and the safety of gas leakage is improved. And harm caused by gas leakage of the gas pipeline in the pipe gallery is reduced.

Description

technical field [0001] The invention belongs to the field of detection and positioning of underground gas pipelines, in particular to a detection and positioning system for underground gas pipelines. Background technique [0002] In recent years, there has been a high incidence of safety accidents in the underground gas pipeline network. According to incomplete statistics, from 2011 to 2014, there were an average of more than 800 gas accidents in the country each year. These accidents caused heavy casualties and economic losses, and received extensive attention from public opinion. Today, with the continuous progress of society, the gas industry is in While doing a good job in external services, we should actively improve the quality of the enterprise itself. Emergency repair is an important window for the gas industry to provide social services. The free leakage of gas can also show the good style of the gas industry through the good quality of emergency repair personnel; ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the shortcomings of the existing technology, the existing underground gas pipeline detection and positioning system in the prior art has simple interaction, less interactive information and is not intuitive, and the detection method of the gas pipeline in the pipe gallery is single.
