Abstract

The invention discloses a fluid pipeline leakage source positioning system and method, and relates to the technical field of pipeline detection. According to the fluid pipeline leakage source positioning system and method, the problem that a leakage source position in a fluid pipeline obtained through calculation by a fixed sound wave propagation speed in the prior art is inaccurate is solved. Thefluid pipeline leakage source positioning system comprises a master station unit and n substation units, each sub-station unit communicates with a fluid pipeline, furthermore, the n sub-station unitsare sequentially distributed in the direction of the fluid pipeline, and the main station unit comprises a selection module, a processing module and a control module, wherein the selection module isin interactive connection with each of the sub-station units; and n is larger than or equal to 2. According to the technical scheme, the fluid pipeline leakage source positioning method comprises thefluid pipeline leakage source positioning system, and the fluid pipeline leakage source positioning system is used for detecting a pipeline leakage source.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a fluid pipeline leakage source locating system and method. Background technique [0002] In recent years, catastrophic accidents caused by oil and gas pipeline leakage have occurred frequently, and the safe operation and maintenance of pipelines have been threatened and challenged. Therefore, it is necessary to use advanced scientific means to establish a pipeline safety pre-alarm system, monitor fluid leakage accidents in pipelines in real time through effective technical means, accurately issue leakage alarms and quickly locate them, so that production units can start corresponding emergency plans and reduce similar safety hazards. Accidents happen. [0003] At present, the monitoring methods for fluid leakage in pipelines mainly include: pressure point analysis method, negative pressure wave method, flow difference monitoring method, optical cable monitoring metho...
