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.
