AI Technical Summary

Benefits of technology

This patented technology describes two examples: One involves creating a device that can monitor assets' parameters like temperature or pressure without being physically attached to it for easy maintenance purposes. Another aspect includes developing systems with sensors placed near assets to measure their properties more accurately than traditional methods such as thermometers. These technical improvements make monitoring devices easier and faster compared to current techniques while also improving accuracy over time.

Problems solved by technology

The technical problem addressed by this patented system relates to ensuring safe and efficient use of certain industrial equipment operating within severe conditions like those involving oil exploration/production activities. These machines are subjected to repetitive movements caused by wave action, sea current movement, and external forces on their structure causing potential failures even if they were designed properly. This can lead to significant economic losses when trying to recover them after being deployed again. Therefore it becomes necessary to develop better sensor technology capable of reliably acquiring accurate data about these mechanical components' health status without experiencing any issues related to stress concentration.

Abstract

A sensing and data acquisition system may provide a sensing assembly including a signal conditioner to receive an electrical signal from a sensor affixed onto an asset and supply an encoded digital representation of a sensed parameter. An acoustic modem may be connected to the signal conditioner to receive the encoded digital representation of the sensed parameter and transmit an acoustic signal based on the encoded digital representation of the sensed parameter. A data acquisition line may be proximate to the asset and may be non-contactively coupled to the sensing assembly. The data acquisition line may include an optical fiber acoustically coupled to the acoustic modem and responsive to the encoded digital representation of the sensed parameter transmitted by the modem to effect an optical change in an acoustically-responsive portion of the fiber. The optical change may be measurable to detect the encoded digital representation of the sensed asset parameter.
