The invention provides an elevator fault early warning method and device, and belongs to the technical field of fault early warning. The method comprises the following steps: shooting an elevator door and a passenger by using a camera to obtain image data; detecting the image data to obtain the edge of the elevator door, determining the movement speed of the elevator door on 2N position points in K round trip processes before the current moment according to the edge, and forming a speed vector V by using 2N * K movement speeds; detecting the image data, identifying an abnormal behavior of a passenger, and determining an abnormal behavior vector A within a time period T before the current moment according to the abnormal behavior of the passenger; fusing the abnormal behavior vector A and the velocity vector V to obtain a fusion vector P; inputting the fusion vector P into a pre-trained fault detection model, and outputting fault types within a time period T1 after the current moment; and fault types are sent to elevator maintenance personnel. Early warning can be conducted on elevator faults, and the personal safety of passengers is guaranteed.

    本发明提供一种电梯故障预警方法及装置,属于故障预警技术领域。方法包括:利用摄像头对电梯门以及乘坐者进行拍摄,获得图像数据;对图像数据进行检测,得到电梯门的边缘,根据边缘确定电梯门在当前时刻之前的K次往返过程中,在2N个位置点上的运动速度,利用2N*K个运动速度组成速度向量V;对图像数据进行检测,识别乘坐者的异常行为,根据乘坐者的异常行为确定在当前时刻之前T时间段内的异常行为向量A;将异常行为向量A与速度向量V进行融合,得到融合向量P;将融合向量P输入预先训练好的故障检测模型中,输出当前时刻之后T1时间段内的故障种类;将故障种类发给电梯维护人员。本发明能够对电梯故障进行预警,保证乘坐者的人身安全。
