摘要
利用在人工智能领域广泛应用的麦克风阵列声源定位技术,基于时延估计(TDE,Time Delay Estimation),采用广义互相关(GCC,Generalized Cross‑correlation)算法,并引入相位变换(PHAT,Phase Transform)加权函数抑制噪声干扰,实现给水管道的快速智能泄漏检测。
By using the sound source localization technology of microphone array widely used in the field of artificial intelligence,based on the time delay estimation(TDE),the generalized cross‑correlation(GCC)algorithm is adopted,and the phase transformation(PHAT)weighting function is introduced to suppress noise interference,so as to achieve fast and intelligent leakage detection of water supply pipelines.
