US 2008/0167833 A1 · METHODS AND SYSTEMS FOR MONITORING STRUCTURES AND SYSTEMS

Abstract

Methods and systems for structural and component health monitoring are provided. A system includes a plurality of sensor systems positioned about an object to be monitored and a processing system communicatively coupled to at least one of said plurality of sensor systems wherein the processing system includes an ontology and reasoning module configured to model the object to be monitored, reason about the received sensor data associated with the object to be monitored and reason about the relationships between the received sensor data to fuse the data into contextual information for the overall object to be monitored and a contextual analyzer configured to transmit the received sensor data to said ontology and reasoning module and to store the information into a contextual information database.

Dependent claims

A structural and component health monitoring system comprising:

a plurality of sensor systems positioned about an object to be monitored;
a processing system communicatively coupled to at least one of said plurality of sensor systems, said processing system comprises:
an ontology and reasoning module configured to model the object to be monitored, reason about the received sensor data associated with the object to be monitored and reason about the relationships between the received sensor data to fuse the data into contextual information for the overall object to be monitored;
and
a contextual analyzer configured to transmit the received sensor data to said ontology and reasoning module and to store the information into a contextual information database.

2 more elements

A sensor networking system for monitoring the health of an aircraft structure and system components related to the aircraft, said system comprising:

a plurality of sensor systems positioned about the aircraft, said sensor systems comprise a flexible substrate, an energy harvesting system, a rechargeable battery, and a microprocessor that controls wireless communication between at least one of said sensor systems and a processing system remote from said plurality of sensor systems, said plurality of sensor systems further comprising sensors including a plurality of different modalities;
and
a processing system communicatively coupled to at least one of said plurality of sensor systems, said processing system configured to receive at least one of sensor data and fused sensor data, said processing system comprising a situation awareness analyzer configured to determine an overall present state of the aircraft by observing the events and activities within the aircraft structure and aircraft systems using the plurality of sensor systems and correlating individual data elements and behavioral models to deduce overall system state and behavior.
