摘要
声纹检测属于一种生物技术,通过提取设备声音特征参数和声纹特征,将音源信号转换为电信号,通过监测电信号变化掌握设备的运行状态。近年来,国内外学者围绕声纹监测的应用开展了研究,主要研究方向包括:机械设备的异常监测、变电站内异常振动信号频谱分析检测、设备异常声音特征提取等。开关柜的主要作用包括:提高电力系统在运行过程中的稳定性、协调电力系统与用户间的电能分配、电力传输的精准控制。开关柜对提高电力系统的稳定性至关重要。因此,在工业生产企业中,开关柜运行状态直接影响企业的经济效益与安全效益。
Voiceprint detection is a type of biotechnology that extracts acoustic characteristic parameters and voiceprint features of equipment,converts audio signals into electrical signals,and monitors equipment operation status by detecting changes in electrical signals.In recent years,domestic and foreign scholars have successively conducted research on the application of voiceprint monitoring.The main research directions include:abnormal monitoring of mechanical equipment,spectrum analysis and detection of abnormal vibration signals in substations,and feature extraction of equipment abnormal sound.The main function of switchgear include:improving the stability of the power systems during operation,coordinating energy between the power systems and users,and control of power transmission.Switchgear plays a crucial role in improving the stability of power systems.Therefore,in industrial production enterprises,the operating status of switchgear directly affects the economic and safety benefits of the enterprise.
