Facility failure prediction system and method for using acoustic signal of ultrasonic band

A facility failure prediction system comprising:

• a detection sensor positioned adjacent to a facility and configured to collect an acoustic signal from sound generated when the facility operates;
• a sampling data extractor configured to sample the acoustic signal, to cancel noise, and to extract sampling data;
• a signal discriminator configured to determine whether the sampling data is a normal signal or an abnormal signal and to generate a plurality of labeling information;
• an abnormal signal analyzer configured to analyze the sampling data corresponding to abnormal signal labeling information determined as an abnormal signal among the plurality of labeling information and to generate abnormal signal analysis information;
• and
• a pattern analyzer configured to analyze a pattern of normal signal labeling information determined as the normal signal among the plurality of labeling information and the abnormal signal analysis information and to provide failure prediction information for the facility.
