Structure health monitoring using wireless sensor networks on structural elements

A Review of Studies in Structural Health Monitoring (SHM)

“…To examine the changes in the static and/or dynamic characteristics of the structure while monitoring their dynamic and/or static responses gives rise to the need of the development of the additional global damage detection methods which can be applied to the complex structures as well. The response-based techniques have the potential to evaluate the whole structure due to its simple setup and potential automation of data acquisition, data processing, and defect detection, [5], [10], [18]. Performance of the structures are determined by various factors such as the age of the building, material used, service condition and layout of the structure besides performance, safety, reliability and serviceability are also the crucial points.…”

“…SHM technology is implemented in various countries like Europe, USA, Korea, Japan etc. for monitoring of large structures [4], [5], [7], [10], [13], [16]- [18] [19]- [21]. The main aim behind the implementation of SHM is to determine the damage during initiation itself so that the further damage propagation can be ceased by an alarm in the initial stage with the help of continuous monitoring by structurally integrated sensors.…”

“…A novel framework to fuse structural health monitoring (SHM) data from different in-situ monitoring techniques is proposed aiming to develop a hyperfeature towards more effective prognostics. [18] The authors discussed the review of structures with structural health monitoring system.…”

A Secure Internet of Things based Smart Monitoring System

“…A low-cost sensor network system implementation to monitor crucial parameters in an indoor environment is proposed in the paper [11].To provide a improved risk management strategy to prevent causalities in a Reinforced Concrete (RC) and masonry building during earthquake and floods, a monitoring system is proposed in paper [12] which screens the health of the structural elements in RC and warn the authorities if there is any physical damage. The paper [13] has presented a water quality monitoring system using WSN to supply clean and safe water. The laborious, time consuming, ineffective method of conventional monitoring process which involves a long procedure, from collecting the samples manually and to send them to laboratory for analysis to get the results which are not real-time in nature has been replaced by an alternative process based on WSN which are very affordable and can be operated remotely and provide real-time results with least human intervention.…”

Embedding principal component analysis for data reduction in structural health monitoring on low-cost IoT gateways

“…A very promising IoT application is Structural Health Monitoring (SHM) [2,24] whose aim is to provide information about the building conditions. To improve the maintainability of large structures such as space vehicles [10], masonry buildings [4], or bridges [20], large sensors networks are installed and supervised by local gateways. These monitoring systems continuously acquire and transmit data to a central unit for storage and processing purposes.…”
