Industrial IOT Enabled SHM Systems

Abstract

The new generation of Industrial Internet of Things (IIOT) will transform the Industrial Age to the Information Age by exploiting opportunities and benefits offered by Information Age technology and techniques. Assets and infrastructure continue to drive innovation in systems and deployment of IOT technologies that have the potential to deliver new capabilities and cost savings. A key enabler for IIOT are sensors and data procured from them. Sensor based IOT devices can gather more data, facilitate more complex analysis and faster reactions, and reduce human error, delivering more precise and efficient military capabilities. Sensor network based Structural Health Monitoring (SHM) systems have the potential to provide real-time and historical sensor based data on the integrity of any structural platform to enable IIOT. SHM systems can reliably detect, localize and quantify damage in components in existing and new structural assets and use the identified damage to make a decision on when to remove the component or for prognosis of the remaining useful component life and system performance. Platform readiness, minimization of costs from unnecessary teardowns, as well as enhanced safety are some of the major goals of SHM. This paper provides examples of SHM systems developed for use in various platforms for in-situ and remote sensing. In-situ on-board sensing, off-board sensing and data transfer along with remote data collection process over long distances for multiple platforms are discussed. Key components will be identified and discussed. Data analysis and data management for multiple platforms to enable IIOT are presented.
