Title

Wireless Network and Embedded System for Autonomous Real-Time SHM

Abstract

This paper describes the real-time monitoring, communication, and alerting capabilities of the SmartBrick, a low-cost, autonomous wireless device for SHM. It is a fully self-contained monitoring platform that requires no additional on-site equipment to collect data and generate alerts. The SmartBrick has several sensors for monitoring temperature, water level, tilt, vibration, and acoustic emissions, and can optionally be used with a digital camera, displacement sensors, load cells, strain gauges, or a wide range of other analog or digital sensors. It uses the widely-available GSM/GPRS network to send monitoring data and alerts to a number of users via FTP, SMS, and e-mail. Its rugged construction, completely wireless design, and extensive powersaving measures allow for a field life of 3-4 years powered only by alkaline batteries. Specifically, this paper presents a major enhancement to the Smart Brick: the addition of short-range wireless communication capability. This addition will allow several SmartBrick devices to coordinate data collection and aggregate data before uploading recorded measurements. This will improve system reliability and facilitate monitoring of larger or subdivided structures, e.g., a bridge with multiple spans.
