SYSTEM AND METHOD FOR DIAGNOSING SOUND OF POWER DEVICE

摘要

PURPOSE: An electric device sound diagnosis device is provided to enable a user to rapidly control the failure of an electric device. CONSTITUTION: An electric device sound diagnosis device (200) comprises a sound detector (220), a signal processor (240), and a diagnosis unit (260). The sound detector detects sound generated from an electric device and transits a sound signal related to the sound. The signal processor converts the sound signal into an analog signal and the analog signal into a digital signal. The diagnosis unit diagnoses the current condition of the electric device based on the converted digital signal and displays the current state. The diagnosis unit determines the abnormal state of the electric state and transmits one or more alarm messages to a mobile terminal or a center control server.
