Abstract

The invention relates to the technical field of pressure pipeline leakage detection and discloses a pipeline leakage detecting method and system as well as a sampler and host thereof in order to solve the problem that misjudgement is easily caused by single leakage detecting instruments because flow rates or pressures of liquids and gases in pipelines are changed. The pipeline leakage detecting method disclosed by the invention comprises the steps of arranging a group of samplers in a leakage detecting region of a pipeline in a linear array or matrix way; and setting the working mode of the host to be a wireless mode, then, indicating the samplers in the group to simultaneously acquire data, storing sampled data of each sampler block by block according to the serial number of the sampler, and determining the position of a leakage point through comparative analysis on the synchronously sampled data of each sampler.

Description

technical field [0001] The invention relates to the technical field of pressure pipeline leak detection, in particular to a pipeline leakage detection method, system, sampler and host. Background technique [0002] With the rapid development of construction and the passage of time, urban water supply pipelines are affected by many factors, resulting in local leakage, such as natural aging, uneven settlement of the foundation, impact of traffic load, soil salinization, impact of municipal construction, Poor plumbing construction etc. However, for the leakage of pipelines in the city, due to the unsatisfactory leakage detection effect of the existing leakage detection equipment, timely management and repair cannot be carried out, thereby causing a waste of water resources. Existing leak detection equipment mainly judges by collecting the leakage signal, and the leakage signal is greatly affected by the environmental noise, the sound transmission characteristics of the pipelin...
