Health-Enabled Smart Sensor Fusion Technology
- Created: Sunday, 01 January 2012
A process was designed to fuse data from multiple sensors in order to make a more accurate estimation of the environment and overall health in an intelligent rocket test facility (IRTF), to provide reliable, high-confidence measurements for a variety of propulsion test articles.
The object of the technology is to provide
sensor fusion based on a distributed
architecture. Specifically, the fusion
technology is intended to succeed in
providing health condition monitoring
capability at the intelligent transceiver,
such as RF signal strength, battery reading,
computing resource monitoring,
and sensor data reading. The technology
also provides analytic and diagnostic
intelligence at the intelligent transceiver,
enhancing the IEEE 1451.x-based
standard for sensor data management
and distributions, as well as providing
appropriate communications protocols
to enable complex interactions to support
timely and high-quality flow of
information among the system elements.
Troubleshooting is simplified through sensor fusion that allows users to interface and verify all sensors via Web-based interfaces. Confidence is improved in decisions due to the use of fusion algorithms. Performance is improved in ad verse environmental conditions. Costs for setup and teardown are reduced. Recalibration when replacing sensors is not required as the data acquisition system can autonomously recalibrate itself. The costs for installation, maintenance, and upgrades for measurement and control systems are also reduced.
