Real-time monitoring system for damage diagnosing on civil structures using the Internet of Things (IoT)

Abstract

This article presents the evaluation of a real-time monitoring system based on acceleration data obtained from a reduced-scale 5-story building prototype. Development is achieved under the Internet of Things (IoT) approach through the cloud using the MQTT messaging protocol. The damage evaluation is achieved by comparing 2 different states of the structural system, for this, the parameters of the civil structure model are used, which are estimated using the normalized least squares algorithm with forgetting factor. In this stage, the algorithms are programmed in Matlab-Simulink and executed on a RaspBerry PI 4. The experimental results confirm the versatility of the proposal and the relevance of the used decentralized communication architectures for real-time monitoring.
