Interface design for pc-based real-time tele-remote operation of an instrumented bridge condition monitoring system

Abstract:For the past 4 years a multidisciplinary team of researchers at the University of Cincinnati Infrastructure Institute (UCII) has been studying the development of instrumented monitoring based condition assessment methods by making use of two fully operational reinforced concrete deck on steel stringer bridges in the Cincinnati, OH area. The instrumentation packages allow for the measurement of ambient conditions, as well as low frequency and high frequency components of structurally related signals. In addition, each bridge is equipped with a weigh-in-motion (WIM) scale which allows the weight and speed of all vehicles crossing the bridge to be monitored. All measurements are recorded by a PC- based data acquisition system. Both bridges are tele-remotely operable from laboratories at UCll via standard telephondmodem connections and custom designed software forming a user friendly data acquisition system interface. This paper reports on the current status of the research effort behind the development of the monitor and its associated user interface.
