The invention relates to an elevator emergency stop people trapping fault detection method based on multi-model fusion. The elevator emergency stop people trapping fault detection method comprises the steps that S1, acceleration data, audio data and image data in an elevator car in the elevator running process are collected; S2, data preprocessing is performed on the acceleration data and the audio data, and acceleration features in the acceleration data and audio features in the audio data are respectively extracted; S3, abnormal acceleration detection is carried out based on the acceleration features and an abnormal acceleration detection result is obtained, and abnormal sound detection is carried out based on the audio features and an abnormal sound detection result is obtained; and S4, the abnormal acceleration detection result and the abnormal sound detection result are fused, and whether an emergency stop fault alarm is generated for an elevator or not is judged based on the fusion result. The scheme can be realized only based on sensors and in cooperation with monitoring camera equipment, so that the use cost and the installation difficulty are greatly reduced.

    本发明涉及一种基于多模型融合的电梯急停困人故障检测方法,包括:S1.分别采集电梯运行过程中的加速度数据、音频数据和电梯轿厢内的图像数据;S2.对所述加速度数据和所述音频数据进行数据预处理,并分别提取所述加速度数据中的加速特征和所述音频数据中的音频特征;S3.基于所述加速特征进行异常加速度检测并获得异常加速度检测结果,以及基于所述音频特征进行异常声音检测并获得异常声音检测结果;S4.对所述异常加速度检测结果和异常声音检测结果进行融合,并基于融合结果判断是否针对所述电梯产生急停故障告警。本发明的方案只需要基于传感器并配合监控摄像头设备即可实现,极大的降低了使用成本和安装难度。
