Steam pipelines are ubiquitous in industrial enterprises and are one of the most important equipment.Once a steam leak occurs,it can waste energy,affect production quality,and even cause safety accidents.Due to the fact that steam pipelines are often located in hidden locations in factories,once a leak occurs,no one will notice it except for daily inspections.So,in order to detect steam leaks in a timely manner,a steam leak alarm and monitoring system based on voiceprint recognition has been developed.Due to the steam pipeline being in a closed space and no other equipment operating around it,there is almost no problem of sound interference.Identify and locate the sound within the gas leakage frequency band using a sound source localization algorithm through a whole array of microphones.The ex-perimental results show that through specific frequency bands and voiceprint recognition,the recognition rate of steam leaks can be effectively improved,and automatic recognition and alarm of steam leaks can be achieved.
