The invention relates to the technical field of elevator safety, and discloses a method for judging stable operation of an elevator cable through sound analysis of an elevator camera, which comprises the following steps of: mounting a camera and audio acquisition equipment: mounting the camera with the audio acquisition equipment in an area close to cable operation in an elevator, therefore, the sound of the cable in operation can be recorded clearly. According to the method for judging stable operation of the elevator cable through sound analysis of the elevator camera, friction and vibration sounds during operation of the elevator cable are collected through built-in audio collection equipment of the camera, and noise reduction, filtering, standardization and other operations are carried out on the collected and reported sounds; and the processed sound spectrum is recorded into a standard support vector machine (SVM) model for modeling, information collected and reported in real time is compared and analyzed in the standard model, and whether the elevator is in a normal operation range interval or not is judged.

    本发明涉及电梯安全技术领域,且公开了一种通过电梯摄像头声音分析判断电梯电缆运行稳定的方法,包括以下步骤:安装摄像头与音频采集设备:将带有音频采集设备摄像头安装在电梯内部靠近电缆运行的区域,确保其能够清晰地录制电缆运行时的声音。本发明所述的一种通过电梯摄像头声音分析判断电梯电缆运行稳定的方法,通过摄像头内置音频采集设备采集电梯电缆运行时的摩擦、震动声音,对采集上报声音进行降噪、滤波、标准化等操作,将处理后的声音频谱录入标准支持向量机(SVM)模型中进行建模,对实时采集上报的信息在标准模型中进行对比分析,判断电梯是否在正常运行范围区间。
