Zusammenfassung:The invention relates to an elevator alarm sound detection system based on audio features; an operation process identification module is used for identifying whether an elevator has an operation process; an audio data processing module is used for performing feature construction on audio data to form a first audio feature and a second audio feature; a model fitting module comprises a first alarm sound detection module and a second alarm sound detection module and is used for carrying out alarm sound detection on the first audio feature and the second audio feature; and an output module is used for giving out alarm sound. According to the elevator alarm sound detection system, the first audio feature and the second audio feature are respectively formed by performing feature construction on the audio data and are respectively input into the first alarm sound detection module and the second alarm sound detection module for alarm sound recognition; the alarm sound is given out when the two modules recognize the a
