Gas pipeline leakage remote detection device, method and system based on infrasonic wave

Abstract

The invention provides a remote detection device, a method and a system for the detection of the leakage of the natural gas pipeline, which are based on the infrasonic wave. The detection device comprises that an infrasonic wave sensor element which is mounted on the detecting natural gas pipeline detects the leakage infrasonic wave signal in the pipeline to produce the sensor data; a data processing element is coupled with the infrasonic wave sensor element to receive the sensor data, analyze the data, identify and process the leakage and produce the processing result data; a time sequence collection element is coupled with the data processing element to receive the synchronous time base signal and synchronize the time clock according to the synchronous time base signal; a communication interface element is coupled with the data processing element for the output of the sensor data and the processing result data; a display element is coupled with the data processing element for the display of the sensor data and the processing result data.

Description

technical field [0001] The present invention relates to natural gas pipeline detection technology, in particular to natural gas pipeline leakage detection technology, especially to a natural gas pipeline leakage remote detection device, method and system based on infrasonic waves. Background technique [0002] At present and in the next few years, it is the peak period for the construction of long-distance gas pipelines in my country. It is estimated that the length of new pipelines will reach 12,000 kilometers. The second transmission line and the Zhongwu line, the connection line of the second Shaanxi-Beijing line and the branch line. Formed in 2015: a multi-source, multi-user gas supply network with five horizontal lines, two vertical lines, three stations, six reservoirs, and seven pipeline networks. However, the leakage of natural gas pipelines will cause serious consequences such as environmental pollution, combustion and explosion, and will cause great direct and indi...
