The invention belongs to the technical field of voiceprint recognition, and particularly relates to a voiceprint recognition method and system for elevator running state monitoring, which can adapt to sound changes under different working conditions by dynamically adjusting a voiceprint feature model, effectively remove noise interference and enhance sound features. According to the method, a sound identification map reflecting sound characteristics during normal operation of the elevator is constructed, difference points are recorded by comparing newly-collected sound with the identification map, whether the elevator state deviates from a normal range or not is evaluated according to the difference points, and finally a maintenance or alarm signal is triggered according to an evaluation result. According to the method, the accuracy and the reliability of the monitoring system are improved, the anti-noise capability and the stability of the system are remarkably enhanced, the false alarm rate is reduced, the quick response to the abnormal state is realized, the safe operation of the elevator is ensured, and the maintenance efficiency and the safety are improved.

    本发明属于声纹识别技术领域,具体涉及一种用于电梯运行状态监测的声纹识别方法及系统,本发明通过动态调整声纹特征模型以适应不同工况下的声音变化,有效去除噪音干扰并增强声音特征。该方法构建反映电梯正常操作时声音特性的声音标识图谱,通过比对新采集的声响与标识图谱记录差异点,并依据这些差异点评估电梯状态是否偏离正常范围,最终根据评估结果触发维护或警报信号。这种方法不仅提高了监测系统的准确性和可靠性,还显著增强了系统的抗噪能力和稳定性,降低了误报率,并实现了对异常状态的快速响应,确保电梯的安全运行,提升了维护效率和安全性。
