Title:
THERMOELECTRIC ENERGY HARVESTING-BASED PIPELINE MONITORING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/111700
Kind Code:
A1
Abstract:
A pipeline monitoring system and a method therefor are disclosed. The pipeline monitoring system comprises: at least one wireless sensor node; a smart gateway for receiving sensing values wirelessly transmitted from the at least one wireless sensor node; and a monitoring server for analyzing and monitoring the state of a pipeline on the basis of the sensing values received from the smart gateway and outputting a result of the monitoring. The at least one wireless sensor node comprises: a thermoelectric energy harvesting device including a thermoelectric device having one surface connected to a portion of a liquefied natural gas pipeline and another surface connected to a buffer member in the atmosphere to generate electric power by a difference in temperature between the one surface and the other surface; at least one power storage source for storing the power generated by the thermoelectric energy harvesting device; a sensor connected to the pipeline to sense various pieces of state information; and a communication module for wirelessly transmitting the sensed state information by selectively using at least one communication protocol.
