Executive Summary

In this paper, a complex wireless sensing unit is designed for application in structural health monitoring systems. Fabricated from advanced embedded system technologies, the fundamental building block of the system is a wireless sensing unit capable of employing a spread-spectrum wireless modem for peer-to-peer communication between sensing units and a complex 32-bit computational core for local data interrogation in real-time. The computational capabilities of the prototype structural health monitoring system design can be utilized for execution of embedded engineering analyses such as damage detection and system identification. To illustrate the computational capabilities of the system, methods for fitting auto-feedback time series models are executed as algorithms embedded in the units of system.
