The invention relates to a stair anomaly detection device and method and an escalator. A step anomaly detection device is characterized in that a groove is formed in one side, facing an apron board, of a step of an escalator, and the step anomaly detection device comprises a distance measuring sensor, a host velometer and a host velometer. The distance measuring sensor is arranged on one side of the apron board, the analysis controller is in communication connection with the distance measuring sensor and the host velometer, and the analysis controller can receive host pulse waveforms output by the host velometer and can receive pulses output by the distance measuring sensor; and during the operation period of the host, the analysis controller compares the received first level pulse with the host pulse waveform, and if the first level pulse is in a continuous interval and the number of host pulses in the host pulse waveform exceeds a set value, an abnormal signal is output. The stair abnormity detection device can find the abnormity of the stairs in time, and is beneficial to improving the safety of the escalator.

    本申请涉及一种梯级异常检测装置、检测方法及扶梯。一种梯级异常检测装置,扶梯的梯级朝向裙板的一侧设置有凹槽,梯级异常检测装置包括测距传感器、主机测速器及主机测速器。测距传感器设置在裙板的一侧,分析控制器分别与测距传感器和主机测速器通讯连接,分析控制器能够接收主机测速器所输出的主机脉冲波形以及能够接收测距传感器所输出的脉冲;在主机运转期间,分析控制器将所接收到的第一电平脉冲与主机脉冲波形做比对,若第一电平脉冲在持续区间内,主机脉冲波形中的主机脉冲个数超过设定值,则输出异常信号。该梯级异常检测装置能够及时发现梯级的异常,有利于提高扶梯的安全性。
