FAILURE ALARM SYSTEM AND METHOD OF FAILURE ALARMING THEREOF
First Claim
1. A failure alarm system adapted for monitoring an instrument, comprising:
- 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 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 new voice eigenvector with the pervious voice eigenvector saved as the historical data to judge whether the instrument is at abnormal working state; and
a warning unit connected to the BUS for warning the monitoring personnel when abnormal state is detected.

4. A method of failure alarming of the failure alarm system, comprising:
-
recording the operating sounds of the instrument with the recording device in a controlled situation where the instrument is ensured to work normally periodically, converting the operating sounds recorded in the controlled situation into a voice eigenvector by means of the voice processing unit and storing the voice eigenvector into the storage unit as historical data; keeping on recording the operating sounds of the instrument in actual operation with the recording device; converting the operating sounds recorded in actual operation into a new voice eigenvector by means of the voice processing unit too; comparing the new voice eigenvector with the pervious voice eigenvector saved as the historical data to judge whether the instrument is at abnormal working state; and warning the monitoring personnel when the compare result shows the abnormal working state occurs, and storing the new voice eigenvector of the instrument at the abnormal working state into the storage unit. - View Dependent Claims (5, 6, 7, 8, 9)
