The invention discloses an elevator running state evaluation system and method based on sound feature extraction. The system comprises a sound collection unit, a human and elevator data separation unit, a human voice analysis unit, an elevator sound analysis unit and an alarm unit. The method specifically comprises the steps that S1, collecting and converting sound signals in an elevator car and a machine room into original sound of the elevator car and original sound of the machine room; S2, separating the original sound of the elevator car into elevator car operation sound data and human voice data; S3, analyzing the human voice data; S4, performing feature extraction on the original sound of the machine room and the elevator car operation sound data, and correspondingly outputting a machine room sound feature value and an elevator car sound feature value; S5, respectively analyzing the machine room sound feature value and the elevator car sound feature value; and S6, evaluating the elevator running state. Through real-time sound data acquisition, the passenger sound, the elevator car operation sound and the machine room sound are analyzed respectively, so that the elevator running state is comprehensively judged, and an elevator is maintained and personnel rescue is carried out in time.

    本发明公开了一种基于声音特征提取的电梯运行状态评估系统和方法,系统包括声音采集单元、人梯数据分离单元、人声分析单元、电梯声音分析单元以及报警单元;方法具体包括S1,采集并转换电梯轿厢和机房中的声音信号为轿厢原始声音和机房原始声音;S2,分离轿厢原始声音为轿厢运行声音数据和人声数据;S3,分析人声数据;S4,分别对机房原始声音和轿厢运行声音数据进行特征提取,并对应输出机房声音特征值和轿厢声音特征值;S5,分别对机房声音特征值和轿厢声音特征值进行分析;S6,进行电梯运行状态评估。通过实时声音数据的采集,分别分析乘客声音、轿厢运行声音和机房声音,从而综合评判电梯运行状态,及时对电梯进行维修和进行人员救助。
