Method for positioning underground pipeline and system thereof

Abstract

The embodiment of the invention relates to a method for positioning an underground pipeline and a system thereof. The method comprises the following steps of: transmitting an electromagnetic wave signal to a wireless radio-frequency positioning marker containing an ID code; receiving a wireless signal which is fed back by the wireless radio-frequency positioning marker and contains the ID code and the underground pipeline information; carrying out checking treatment on the ID code and the underground pipeline information; determining an embedded place name of the wireless radio-frequency positioning marker according to the ID code; determining the embedded concrete position of the pipeline; and determining the trend of the pipeline according to the orientation information of the adjacent wireless radio-frequency positioning marker. The embodiment of the invention also provides a positioning system of the underground pipeline. The positioning method and the positioning system in the embodiment of the invention can realize the accurate positioning of the underground pipeline, find fault points as soon as possible when faults happen, reduce the digging area and the compensation cost,furthermore help maintainers establish the records of maintaining in normal times and overhauling the underground pipeline.

Description

technical field [0001] The invention relates to radio frequency information identification technology, in particular to an underground pipeline positioning method and system using the technology. Background technique [0002] With the development of urban construction, various pipelines are often buried underground in cities, such as water pipes, gas pipelines, communication cables, petrochemical pipelines, etc. The daily maintenance and fault repair work of these pipelines is essential. However, in the maintenance and construction of underground pipelines, it is often necessary to excavate a large road surface and take a long time to find the target location of the fault. Find the valve well, add the signal of the pipe finder, and then follow the instructions of the instrument to trace the pipeline step by step until the excavation point. The valve well is hundreds of meters or even farther away from the site, and it takes tens of minutes to complete this process. The work...

However, in the maintenance and construction of underground pipelines, it is often necessary to excavate a large road surface and take a long time to find the target location of the fault. Find the valve well, add the signal of the pipe finder, and then follow the instructions of the instrument to trace the pipeline step by step until the excavation point. The valve well is hundreds of meters or even farther away from the site, and it takes tens of minutes to complete this process. The work efficiency is low, especially in the time of emergency repair, it will waste more precious time
