ULTRASONIC DISTANCE MEASURING DEVICE AND DEFECT DIAGNOSIS METHOD THEREOF

摘要

PURPOSE: An ultrasonic distance measuring device and a fault diagnosis method thereof are provided to easily and rapidly handle faults by precisely analyzing a cause of the faults. CONSTITUTION: An ultrasonic distance measuring device comprises a transmitting part(110), an ultrasonic sensor part(120), a receiving part(160), a transmitting line detection part(130), and a receiving line detection part(170). The transmitting part transmits an ultrasonic generation signal. The ultrasonic sensor part radiates ultrasonic waves depending on the ultrasonic generation signal. The receiving part receives the ultrasonic generation signal output from the ultrasonic sensor part. The transmitting line detection part detects the ultrasonic generation signal transferred to the ultrasonic sensor part. The receiving line detection part detects the ultrasonic generation signal transferred to the receiving part.
