The escalator

which is related to the safety of passengers

is a special equipment

and it is crucial to ensure the safety and stability of its operation. This paper studies the application method of escalator status monitoring and intelligent early warning and diagnosis system. On the basis of mastering the infrastructure of escalator status monitoring and early warning system

sensor installation

system level monitoring platform and so on

it studies the system time domain analysis

frequency domain analysis

envelope analysis

intelligent early warning and other functions. At the same time

it emphasizes the system application environment

real-time monitoring and data analysis

effect evaluation and optimization system application test method

which help to find the escalator running fault

improve the maintenance effectiveness

and achieve the processing goal of fine maintenance.
