Abstract

This paper describes a prototype system being developed for on-line structural monitoring of the cathedral of Como, Italy. Monitoring is based on relative displacement and temperature measurements employing optical fibre Bragg grating transducers. System features include an edge-filter demodulation scheme with wavelength multiplexing, palmtop-based control with customised software, automated data acquisition and analysis and GSM-based data transmission via email. The system also offers the option to be solar powered, allowing it to be located in areas with limited access, such as on the cathedral roof. Initial results obtained over an eight-month demonstration period are also presented. The intention is to develop this prototype into a complete system for on-line structural monitoring of the Cathedral, offering real decision support to those responsible for its maintenance.
