Audio-based mechanical failure detection device

The present utility model discloses an audio-based mechanical failure detection device. Noises given out by the operation of engineering mechanical equipments are collected, converted into sound data, and sent to a processing module by an audio acquisition module; mechanical failure information is determined according to the received sound data and sent to an alarm module by the processing module; and the mechanical failure information is displayed to users by the alarm module. Thus, by adopting the device, the failure information can be obtained and an alarm can be given out in real time, the real-time performance is good. and the success rate of failure identification can be substantially increased. Moreover, the device opens a new way in the field of engineering mechanical equipment failure identification, and has high practical values.
