Monitoring pipeline integrity
First Claim
1. A computer-implemented method of detecting and responding to a threat condition, comprising:
- receiving, at a monitoring assembly, an input acquired in proximity to a pipeline of a fluid distribution system through which fluid is flowing, the input comprising data associated with a measurement of a vibration characteristic of the pipeline, wherein the data is acquired by a sensor positioned exterior of the pipeline;
determining, by the monitoring assembly, whether the input indicates a threat condition for the pipeline by comparing the data to a baseline vibration measurement of the pipeline, the baseline vibration measurement having been previously recorded;
wirelessly transmitting, by the monitoring assembly, via an antenna of the monitoring assembly and in response to a determined threat condition, a first message for receipt by a first valve assembly associated with a first fluid transmission valve of the pipeline and a second message for receipt by a second valve assembly associated with a second fluid transmission valve of the pipeline, wherein the first fluid transmission valve is located upstream of the monitoring assembly and the second fluid transmission valve is located downstream of the monitoring assembly, and wherein the first message instructs the first valve assembly to cause the first fluid transmission valve to close and the second message instructs the second valve assembly to cause the second fluid transmission valve to close;
wirelessly transmitting, by the monitoring assembly, a third message via the antenna of the monitoring assembly for receipt by a control system of the fluid distribution system, wherein the control system is remote from the monitoring assembly, the third message comprising an indication of the determined threat condition, an indication of the first fluid transmission valve and the second fluid transmission valve, and an identifier associated with the monitoring assembly; and
performing a maintenance routine by periodically at least partially closing and then reopening the first fluid transmission valve or the second fluid transmission valve.

Abstract
A method of detecting and responding to a threat condition includes receiving, at a sensing module, an input acquired in proximity to a pipeline of a fluid distribution system, the input including data associated with a vibration measurement of the pipeline acquired by a sensor exterior of the pipeline. The method also includes determining whether the input indicates a threat condition by comparing the data to a previously recorded baseline vibration measurement. The method further includes automatically closing a first fluid transmission valve in response to a determined threat condition, thereby restricting flow of fluid through the pipeline in a vicinity of the first fluid transmission valve, and wirelessly transmitting a message for receipt by a control module that is remote from the sensing module, the message including indications of the determined threat condition, the first fluid transmission valve, and an identifier associated with the sensing module.
