| Abstract: |
The ability to monitor the condition of a naval structure to detect damage or property changes at early stages is of significant interest. We proposed to develop a ship structure monitoring system that is low cost, modular, and easily deployable. The system incorporates various types of sensors and provides early warning of critical structural problems through cooperative data processing and diagnosis. With minimal human intervention, the system can potentially achieve real-time "smart" health monitoring of critical ship structures and measure the loads and stress level for the safety of ship operation. |
| Benefits: |
Navy ships' structural condition is very important for safely transporting naval assets and for mission success. Our proposed wireless multi-sensor network system will be able to detect and localize growing defect in ship structures, monitoring load/stress levels for operation safety, and saves costs in maintenance.
Besides military applications, civil infrastructures also represent significant investments within the United States. Almost 4 billion vehicles cross bridges every day in the United States. An effective way of health monitoring of those bridges represents a critical issue for public safety and economics. It is very important to develop low cost and reliable nondestructive inspection and monitoring technique to detect the onset of failures so that necessary precautions can be taken to prevent hazards. Our proposed wireless in situ structural health monitoring system exactly achieves the purpose of early and convenient detection of defects and hence improves safety of the structure and saves costs in maintenance.
