In industrial environments, transient sounds are often accompanied by equipment anomalies and failures. Monitoring of transient sound helps to detect hidden equipment problems and malfunctions in time, improving productivity and safety. In this paper, a distributed array source localization algorithm based on the conic affiliation function(CAF) is proposed by using the time-domain beamforming and fuzzy logic fusion method for transient acoustic source localization under a wide range of space. The energy-weighted fusion of different array types with different numbers of array elements is also performed to apply different microphone array localizations. In this study three microphone arrays of different array types with different numbers of array elements were used to capture transient sound, and each array was used to estimate the source location individually, then fuzzy logic with CAF is used for data fusion to precise the sound source location. The experimental results show that the distributed array localization effect is better than the three single-array localization effect, and the localization error is reduced by 0.2 m by using the distributed array. the localization accuracy is better.
