The Software Demo of Acoustic Imaging for Equipment Fault Detection

Abstract

Equipment faults often produce the abnormal sound; the acoustic imaging detection can test the equipment faults remotely and visually. In many applications, especially in safety related area, it can extern the monitor fields and improve detecting ability. The function of software design is to show the photo and sound imaging. In this paper, acoustic imaging software design method of equipment fault diagnostic is proposed. The difference in the time of arrival (TDOA) is used to identify the location of faults. And in a software demo, the two USB microphones and a microphone in PC are used to acquire the sound. The spectral photo and sound is mapped to locate the fault sources.
