The invention discloses a chain extension detection method, system and device for an escalator, and the method comprises the steps: detecting the relative displacement of a chain during the operation of the escalator, collecting the analog quantity of a first displacement in real time, and obtaining a first displacement waveform; the elongation of the chain is calculated according to the reference value and a first characteristic value generated by performing characteristic analysis on the first displacement waveform, and real-time detection of the elongation of the chain for the escalator is realized; the alarm signal is generated when the elongation reaches the preset threshold value, so that timely alarm when the elongation of the chain for the escalator reaches the preset threshold value is realized, the safety risk of passengers is reduced, and meanwhile, timely troubleshooting of escalator faults is facilitated. The method can be widely applied to the technical field of detection.

    本发明公开了一种扶梯用链条伸长检测方法、系统、装置,扶梯用链条伸长检测方法通过检测扶梯运行时的链条的相对位移量,并实时采集第一位移量的模拟量,得到第一位移量波形,根据基准值和对第一位移量波形进行特征分析生成的第一特征值计算得到链条的伸长量,实现了扶梯用链条伸长的实时检测;通过在伸长量达到预设阈值时生成报警信号,实现了扶梯用链条伸长达到预设阈值时的及时报警,降低了乘客的安全风险,同时便于对扶梯故障进行及时排查。本发明可广泛应用于检测技术领域。
