RAILWAY BRIDGE MONITORING SYSTEM AND METHOD USING WIRELESS SENSOR NETWORK

摘要

A bridge monitoring system and method using a wireless sensor network are disclosed. A bridge monitoring system using a wireless sensor network according to an exemplary embodiment of the present invention is a bridge monitoring system using a wireless sensor network that is installed in a bridge to measure an impact load of the bridge at all times, 1 wireless sensor; At least one second wireless sensor that is installed in the bridge but switches from the inactive state to the active state upon receiving the measurement start signal to measure the impact load of the bridge; And transmits a measurement start signal corresponding to the shock generation signal to the second wireless sensor, and transmits a reference time to each of the first wireless sensor and the second wireless sensor at predetermined time intervals The first wireless sensor and the second wireless sensor include a base station for time-synchronizing an internal time based on a reference time and arranging time-synchronized data based on a reference time to synchronize data.
