Abstract

The invention discloses an intelligent noise acquisition device for a mobile inspection platform. The intelligent noise acquisition device is characterized in that: firstly, two omnidirectional noise sensors are used for picking up and outputting noise signals, and sound waves are filtered by using the difference between phases of the sound waves received by the two omnidirectional noise sensors; and then two directional noise sensors are used for picking up noise signals, judging whether the noise is from a target sound source or not, further removing the noise signals of a non-target sound source in a shielding manner, and leaving the noise signals of target equipment, so that the environment background sound can be eliminated to the maximum extent, and only required sound waves are left. When the intelligent noise acquisition sensor is adopted on the inspection platform, noise signals of monitoring equipment can be distinguished more simply and quickly in a noisy environment, noise features are easy to extract, abnormal noise signals are found in time, and noise categories are diagnosed.

Description

Technical field[0001]The present invention relates to the field of mechanical equipment noise monitoring, and more particularly to an inspection platform and a method of use of intelligent noise acquisition devices and inspection platforms.Background technique[0002]Abnormal noise monitoring and analysis of large rotating equipment, in essence, detection, identification, and classification of abnormal noise for operational conditions of the unit. Noise is one of the features of energy leakage at the time of equipment, fluid power vibration, mechanical vibration, and electromagnetic vibration produce operational noise of different characteristics. When a fault occurs, the corresponding part generates an abnormal noise distribution. Timely and accurate discovery of abnormal noise sources, accurately identify the features of these noise, is the necessary means of the fault diagnosis of large rotating equipment.[0003]In the rotation device operation, the mechanical noise contains rich ma...
