Embodiment 1

[0049] Such as figure 1 As shown in , this embodiment discloses a gas pipeline repair method based on Beidou differential positioning. The repair method is a method that can effectively improve the gas pipeline repair efficiency. The repair method specifically includes the following steps.

[0050] Step 1. When welding two connected gas pipelines, use the first Beidou differential positioning device configured on the welding equipment to collect the first positioning data, and upload the first positioning data to the server; where the first positioning data is A collection of junction point location data, the server is used to store the first location data. In this embodiment, in order to improve the accuracy of the first positioning data, the first positioning data collected by the first Beidou differential positioning device is the positioning data corrected by positioning satellites and multiple positioning base stations; in this embodiment, the server will Permanently sav...

Embodiment 2

[0058] Based on the same inventive concept as the first embodiment, this embodiment provides a repair system for realizing the above-mentioned gas pipeline repair method based on Beidou differential positioning, which is described in detail as follows. This embodiment discloses a gas pipeline repair system based on Beidou differential positioning. The system may include welding equipment, detectors, repair equipment, servers, maintenance management terminals, and browsing terminals connected to the maintenance management terminals.

Abstract

The invention discloses a gas pipeline repairing method and system based on Beidou differential positioning. The method comprises the steps that 1, first positioning data are collected and uploaded inthe pipeline welding process; 2, the first positioning data are sent to a detector; 3, second positioning data are collected during maintenance, and a priority detection point is determined by usingthe first positioning data and the second positioning data; 4, if the priority detection point is a leaking point, the step 5 is executed, if the priority detection point is not the leaking point, detection is continued, and the step 5 is performed after the priority detection point is determined to be the leaking point; 5, the position of an excavation point is determined according to the position of the leaking point and the position of a joint point; and 6, the target position is determined according to third positioning data and position data of the excavation point, and the leaking pointof the gas pipeline is repaired after excavation. The system includes connecting equipment, the detector, repair equipment, a server and the like. By means of the gas pipeline repairing method and system, the gas pipeline repairing efficiency can be can significantly improved, the gas pipeline repairing time is shortened, the labor input cost is effectively reduced, and the dependence on the maintenance personnel experience is avoided.

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...
