Prefabricated sensor panels for smart-civil-structures instrumentation

摘要

Abstract: Installation of fiber optic sensors into large civil structures entails either embedding or attaching the sensors to some structural member. While we have performed sensor installations on numerous types and sizes of civil structures, this process is frequently quite labor- and time-intensive - both of which can potentially conflict with construction site practices. In instances where it is desirable to install many sensors in close proximity, it may prove very beneficial to prefabricate panels of sensors and then install the panel into the structure. However, issues such as the effect of the panels on the structural integrity of the building may arise. In this paper we discuss this matter as well as the panel interconnect and sensor interrogation issues. Examples of prefabricated sensor panels designed for installation into a new wing of the Medical Center Hospital of Vermont are then presented. !2
