Failure alarm system and method of failure alarming thereof

摘要

A failure alarm system adapted for monitoring an instrument includes a BUS transmitting data and control logics inside the failure alarm system, a recording device connected to the BUS for recording operating sounds of the instrument, a voice processing unit connected to the BUS for converting the operating sounds into a voice eigenvector, a storage unit connected to the BUS for storing the voice eigenvector at the normal working state of the instrument as historical data and also storing the voice eigenvector at the abnormal working state of the instrument therein, a comparing unit connected to the BUS for comparing the new voice eigenvector with the previous voice eigenvector saved as the historical data to judge whether the instrument is at the abnormal working state, and a warning unit connected to the BUS for warning the monitoring personnel when the abnormal state is detected.
