Remote Real-Time Structure Health Monitoring with MINI-SMIK

Abstract

This paper describes real-time data acquisition for a structure health monitoring solution called MINI-SMIK (sistema monitoringa inzhenernykh konstruktsii—structure health monitoring system). The configuration of the equipment in this work includes two IN120 inclinometers and a DC200 strainmeter. An RC Module MB77.07 single-board computer (SBC) in a special sealed enclosure is used to log and transmit data. The SBC receives data over an RS-485 link then converts it to the miniSEED format and transmits the measurements in real-time to the data center using the SEEDLink protocol. Data can be sent over a local area network or the Internet via wireless (e.g., cellular) networking. Encrypted virtual private networks (VPNs) have been used successfully for secure data transmission via public networks.
