The invention discloses an elevator car passenger abnormal behavior identification method and device, and the method comprises the steps: S1, collecting a vibration acceleration signal through a control variable method with the passenger abnormal behavior type as a variable, calculating a peak value and a kurtosis value, and constructing an evaluation set; s2, constructing a second membership function by using an expert scoring method in combination with the evaluation set, obtaining corresponding experimental probability distribution results when different passenger abnormal behaviors occur, and constructing an abnormality judgment function used for calculating real-time probability distribution corresponding to the passenger abnormal behaviors; s3, collecting a real-time vibration acceleration signal, constructing a real-time signal evaluation set, judging the type of the abnormal behavior of the passenger by using an abnormality judgment function and an experimental probability distribution result, and identifying an abnormality level according to a peak value; and S4, giving an alarm prompt according to the abnormal behavior type and the abnormal level of the passenger. The elevator operation can be monitored, the abnormal behaviors of passengers are recognized, and manual abnormal vibration of the elevator is effectively reduced.

    本发明公开了一种电梯轿厢乘客异常行为识别方法及设备,包括:S1,以乘客异常行为种类为变量利用控制变量法采集振动加速度信号,计算峰值和峭度值,构建评价集;S2,结合评价集利用专家评分法构建第二隶属度函数,获取不同乘客异常行为发生时对应的实验概率分布结果,构建用于计算乘客异常行为所对应的实时概率分布的异常判定函数;S3,采集实时振动加速度信号,构建实时信号评价集,利用异常判定函数和实验概率分布结果对乘客异常行为的类型进行判定,根据峰值识别异常等级;S4,根据乘客异常行为类型和异常等级发出报警提示。本发明可以对电梯运行进行监测,识别出乘客异常行为,有效减少人为电梯异常振动。
