The invention relates to the technical field of escalator diagnosis, in particular to an escalator health condition diagnosis system, which comprises a data acquisition module for acquiring escalator vibration signal original data acquired by a preset escalator side exploration module, forming escalator vibration signal to-be-extracted data after data preprocessing, and transmitting the escalator vibration signal to-be-extracted data to an escalator side exploration module; the characteristic value is represented as data meeting the preset data specification of the characteristic value extraction module; the feature value extraction module is used for sequentially performing feature extraction and feature analysis on the to-be-extracted data of the escalator vibration signals to obtain feature values of the vibration signals of all parts of the escalator, integrating the feature values and inputting the feature values into the working condition recognition module; and the working condition identification module takes the vibration signal characteristic value of each part of the escalator as the input of a pre-trained working condition identification model, and calibrates the operation working condition and potential fault of each part of the escalator based on an output result so as to complete the diagnosis of the health condition of the escalator.
