摘要
蒸汽管道在工业企业中随处可见,并且是相当重要的设备之一。一旦发生蒸汽泄漏,轻则浪费能源,影响生产质量,重则造成安全事故。由于蒸汽管道往往位于工厂隐蔽的位置,一旦泄漏,除了日常巡检,平时很难发现。为了及时发现蒸汽泄漏,研制了1套基于声纹识别的蒸汽泄漏报警监控系统。由于蒸汽管道处于密闭空间,且周围没有其他设备运行,几乎不存在声音干扰问题。通过整列麦克风,利用声源定位算法对气体泄漏频段内的声音进行识别和定位。实验结果表明,通过特定频段和声纹识别,能够有效提高蒸汽泄漏的识别率,实现蒸汽泄漏的自动识别报警。
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 experimental 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.
