Abstract

A method and a system for repairing a gas pipeline based on Beidou differential positioning, the method comprising: step 1: when welding a pipeline, collecting first positioning data and uploading same; step 2: sending the first positioning data to a detection instrument; step 3: during maintenance, collecting second positioning data, and using the first and second positioning data to determine a priority detection point; step 4: if the priority detection point is a leakage point, then executing step 5; and if not, then continuing detection and executing step 5 after determining a leakage point; step 5: on the basis of the leakage point position and a joining point position, determining a digging point position; and step 6: on the basis of third positioning data and digging point position data, determining a target position and, after digging, repairing the leakage point of the gas pipeline. The system comprises a connecting device, a detection instrument, a repair device, and a server. The present method and system can significantly increase gas pipeline repair efficiency, shorten the gas pipeline repair time, effectively reduce manpower costs, and avoid reliance on the experience of maintenance staff.

Description

technical field [0001] The invention relates to the technical field of repairing gas pipelines, and more specifically, the invention relates to a method and system for repairing gas pipelines based on Beidou differential positioning. Background technique [0002] At present, environmental pollution has become a concern of the whole world. In order to protect the environment, people begin to choose more environmentally friendly energy sources. As a clean energy source, gas is used more and more frequently; for the transportation of gas, the gas pipeline used to transport gas is bound to be inseparable; after the gas pipeline has been in service for a period of time, the gas pipeline will leak due to corrosion and other reasons , At this time, maintenance personnel are required to conduct a detailed inspection of the pipeline, and then repair the leak point of the gas pipeline. [0003] However, the gas leakage problem has the characteristics of fluidity and concealment. Conv...
