The invention relates to an escalator step gap monitoring and early warning method. The escalator step gap monitoring and early warning method comprises the steps that the operation periods of two sets of transmission chains of an escalator are detected, the absolute value delta T of the difference value of the two sets of transmission chains is calculated, and the operation periods of the transmission chains are the time required for chain wheels in the transmission chains to sequentially pass through detection points; and whether delta T is larger than delta Tmax or not is judged, delta Tmaxis the upper limit of the operation period difference value of the two sets of transmission chains obtained according an the abrasion test before the escalator leaves a factory, and if delta T is larger than or equal to delta Tmax, a first escalator step gap early warning signal is output. Correspondingly, the invention further designs the escalator with the step gap monitoring and early warningfunctions. The operation periods of the transmission chains on the two sides of the escalator are monitored to serve as a means for monitoring the abrasion loss of the chain wheels and driven wheels on the two sides, automatic early warning can be conducted once the absolute value of the difference value of the operation periods of the transmission chains on the two sides is larger than a set value, real-time monitoring and early warning of the step gap of the escalator can be achieved, and the reliability and safety of the escalator operation are improved.

    本发明涉及一种自动扶梯梯级间隙监测预警方法,包括:检测自动扶梯的两组传动链的运行周期并计算二者的差值绝对值ΔT,传动链的运行周期为该传动链中的各链条轮依次通过检测点所需的时间;判断ΔT是否大于ΔTmax,ΔTmax为根据该自动扶梯出厂前的磨损试验所获得的两组传动链的运行周期差值上限,若ΔT≥ΔTmax,输出第一自动扶梯梯级间隙预警信号。相应地还设计了一种具有梯级间隙监测预警功能的自动扶梯。本发明对自动扶梯两侧传动链的运行周期进行监测,以此作为对两侧链条轮及从动轮磨损量的监测手段,一旦两侧传动链的运行周期差值绝对值大于设定值,可进行自动预警,能实现对自动扶梯梯级间隙的实时监测和预警,提高自动扶梯运行的可靠性和安全性。
