The invention provides an escalator early warning method and a system. The escalator early warning method comprises a quality change perception sensor which is arranged on a pedal of an escalator, wherein the quality change perception sensor detects quality change on the pedal in real time, and sets the range of abnormal quality change. When the quality change on the pedal falls into the range of the abnormal quality change, the quality change perception sensor sends out warming. The escalator early warning method further comprises a plurality of infrared characteristic sensors which are arranged on the two sides of the escalator, wherein the infrared characteristic sensors are used to collect infrared radiation which is sent from objects which are arranged on the escalator, the infrared characteristic sensors analyze characteristic actions of the infrared radiation, and determine whether characteristic actions happen, and when the characteristic actions are determined to happen, the infrared characteristic sensors send out warming. The escalator early warning method and the system can identify some abnormal situations which compromise passenger safety and achieve warming of the escalator.
