The fiber connects the sender-receiver piezoelectric device. The ultrasonic wave transmitter transmits voltage signals to the sender-receiver piezoelectric device, thereby generating ultrasonic waves. The ultrasonic wave receiver receives ultrasonic signals which are a changed form of the voltage signals detected from the piezoelectric device. The strain monitoring part processes strain information from the received ultrasonic signals. The damage information monitoring part processes damage information from the received ultrasonic signals.
