As a new technology, functional safety technology has been widely used in escalators. Functional safety inspection is the basis of escalator maintenance operations. This paper introduces the distribution and application of escalator functional safety, proposes a functional safety inspection method for escalator functional safety based on functional safety theory, and constructs a technical framework for escalator functional safety maintenance operation guidance, including data integrity, working environment, and daily inspection, Sensors, cabinets and control panels, wires and connectors, etc. and inspection methods. On this basis, taking the overspeed inspection of the escalator as an example, the escalator function safety maintenance operation guidance technology is explained.
