Abstract
AbstractIn recent years, structural health monitoring and management (SHMM) has become a popular approach and is considered essential for achieving well-performing, long-lasting, sustainable transportation infrastructure systems. Key requirements in ideal SHMM of road infrastructure include long-term, continuous, and real-time monitoring of pavement response and performance under various pavement geometry-materials-loading configurations and environmental conditions. With advancements in wireless technologies, integration of wireless communications into sensing device is considered an alternate and superior solution to existing time- and labor-intensive wired sensing systems in meeting the requirements of an ideal SHMM. This study explored the development and integration of a wireless communications sub-system into a commercial off-the-shelf micro-electromechanical sensor-based concrete pavement monitoring system. A success-rate test was performed after the wireless transmission system was buried in the c...
Highlights
Like many advanced technologies, wireless sensor technologies were initially developed and deployed for military and industrial purposes (SILICON LABS, 2015)
This paper describes the development and field performance of a wireless micro-electromechanical sensor system (MEMS) for monitoring concrete pavement temperature and relative humidity
These kinds of technologies are extensively applied in civil engineering infrastructure to measure the changes in material and geometric properties for serviceability assessment, which is referred to as structural health monitoring (SHM)
Summary
Wireless sensor technologies were initially developed and deployed for military and industrial purposes (SILICON LABS, 2015) In recent years, these kinds of technologies are extensively applied in civil engineering infrastructure to measure the changes in material and geometric properties for serviceability assessment, which is referred to as structural health monitoring (SHM). Each sensor node could store the data and periodically transmit them to radio frequency (RF) reader mounted on a moving vehicle (Lajnef, Rhimi, Chatti, Mhamdi, & Faridazar, 2011) The objective of this current study is to investigate the feasibility of developing wireless-based MEMS for concrete pavement SHM. Detailed discussions and findings pertaining to the development of wireless-based MEMS are discussed
