Pipeline monitoring unit and method

摘要

A pipeline monitoring unit and method are disclosed. The unit includes a pressure monitoring unit couplable to a pipeline and arranged to monitor fluid pressure in the pipeline over time when coupled to the pipeline and generate data on the fluid pressure at a first sampling rate. A processing unit is arranged to process the data from the pressure monitoring unit to downsample at least a portion of the data from the pressure monitoring unit to a second sampling rate, the second sampling rate being less than the first sampling rate, to generate working data and monitor the samples in the working data for samples having predetermined characteristics to identify a transient event. Upon identifying a transient event, data including at least a portion of the data from the pressure monitoring unit having the first sampling rate is communicated to a remote system for analysis.

1. A pipeline monitoring unit comprising:
a pressure monitoring unit couplable to a pipeline and arranged to monitor fluid pressure in the pipeline over time when coupled to the pipeline and generate data on the fluid pressure at a first sampling rate; a processing unit arranged to process the data from the pressure monitoring unit to:
(a) downsample at least a portion of the data from the pressure monitoring unit to a second sampling rate, the second sampling rate being less than the first sampling rate, to generate working data;(b) monitor the samples in the working data for samples having predetermined characteristics to identify a transient event; and,upon identifying a transient event, communicating data including at least a portion of the data from the pressure monitoring unit having the first sampling rate to a remote system for analysis.
