Citizen Sensors for Structural Health Monitoring [D20]

A crowdsourcing-based, SHM-oriented smartphone application, namely, Citizen Sensors for SHM (CS4SHM) is demonstrated. The demonstration includes vibration measurement from a small-scale structural model, wireless data submission to the web server, and viewing the identification results online. CS4SHM enables users to collect vibration data from smartphone sensors, extract the time history in text format, and submit the data via a web view connected to an online server. The vibration time history received by the server is automatically processed from the time to the frequency domain via Discrete Fourier Transform (DFT). In this way, the server determines the peak frequency and stores the results as well as the raw input data for further post-processing uses. Monitoring the modal identification results over time allows users to notice changes in dynamic characteristics of a structure.
