Abstract:Structural behavior can be characterized as deformation, large strain, crack or failure, foundation release or scour, etc. As such, displacement is the significant parameter to assess the performance of structural stability and safety using the behavior information. A real-time, durable, reliable and low-cost monitoring technique for the exterior and internal displacements is still in great need for the infrastructures under harsh environments. In this paper, a novel displacement field technique based on the smart-labels is proposed to monitor behavior of the infrastructures. The smart-labels mainly can be set up on any kind of wireless tags, such as magnetic matters, radio frequency identification (RFID) tags and even global position system (GPS) measuring sensors, etc. Each node can be used to describe and identify the local structural information at the fixed point, which can be used to configure a new network, internet of things (IOT). In practice, these smart-labels are packaged in certain highly-protected block, namely smart block or rock. The smart block can be attached or embedded directly on the structure so that the information of position and physical parameters can be recorded and transmitted accordingly... The proposed system can be regarded as a real-time, durable, reliable and low-cost displacement field monitoring IOT. And it is feasible to be widely applied in infrastructures ranging from high geological slop, dam embankment and bridge foundation.
