Autonomous Monitoring and Assessment of Sensor Data in Support of Calibration and CBM Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-132 Topic Title: Autonomous Monitoring and Assessment of Sensor Data in Support of Calibration and CBM Proposal No.: N052-132-0418 Firm: Impact Technologies, LLC 200 Canal View Blvd, Ste 300 Rochester, New York 14623-2851 Contact: Michael Roemer Phone: (585) 424-1990 Web Site: www.impact-tek.com Abstract: Impact Technologies, in cooperation with Northrop Grumman Ship Systems, propose to develop and demonstrate a comprehensive sensor health assessment software product that is capable of detecting sensor faults and isolating corrupt data acquired from critical ship systems. The proposed concept is innovative in the fact that it is based on a data-driven modeling methodology, which has generic application to both high and low bandwidth signals, and is capable of detecting subtle changes in signals resulting from calibration or sensor drift issues. In addition, based on the fact that the approach is highly scalable (not limited to the number of sensors), it can be applied across any ship system and readily support the condition-based maintenance (CBM) and mission readiness philosophies expressed in the DD(X) program. The signal health software modules, will not only be capable of real-time sensor fault detection (wired or wireless), but it can also recover from the sensor faults using the signal's predicted value until the sensor is repaired or replaced. This will allow the ship systems being monitored to continue to operate as normal without the need for abrupt maintenance actions that are costly to mission readiness and effective operations. Finally, the signal monitoring modules will operate in both transient and steady-state modes and will be implemented within an open-systems, modular software architecture suitable for any 3rd party system integration. Well-documented, dynamic link library (DLL) modules will be tested on selected NG systems relevant to DD(X) and delivered during Phase I for assessment into existing modular architectures such as the Navy's ICAS. Benefits: The successful completion of the proposed work will substantially improve the performance, reliability, and survivability of monitoring systems for both military and commercial ship systems, as well as aircraft systems. The potential military and commercial use of the developed technologies is broad, with specific application to the DD(X) program and legacy DDG and CG platforms. Examples of other key customers aside from the Navy that could benefit through use of the developed technologies include: unmanned combat air vehicles, future combat systems, commercial airlines, land and marine propulsion systems, industrial actuation systems, and robotic applications. The ship and aircraft domain alone has thousands of potential systems to address with this technology. Return
