IoT-based microseismic monitoring system for the evaluation of structural health in smart cities

Abstract

This paper presents the design and implementation of a prototype station, which aim to monitor microseismic events. The data collected by the sensors are used for detecting events on a specific zone, as well as for applications of structural health. The prototype was implemented using IoT devices (Internet of Things), such as MEMS accelerometers (Microelectromechanical Systems) and a single board computer with embedded Linux. The station can be accessed remotely by means of a web application based on Node.js, which provides users with real time data. Moreover, the prototype has the capacity of getting information of geolocation as well as platform status (e.g. CPU load, temperature and energy consumption). The main advantage of this proposal consists in the design of a solution based on open hardware architecture, open source, portability and low cost. Regarding the prototype evaluation, results show an appropriate operation, which represents the contribution of this work to the design of monitoring applications in the context of smart cities.
