Functional safety integrity verification method of public transportation escalator

To improve the safety management of escalator management, especially the safety management level of public transportation escalators, it is necessary to study the safety integrity verification methods of public transportation escalators. This article introduces the definition and calculation method of the integrity level of escalator safety functions. The risk diagram method is used to calculate the escalator functional safety functions. The article points out that as an important part of escalator safety, functional safety includes system safety functions and safety functions execution ability, through research and verification of calculation methods, it helps to improve the safety and reliability of escalators, and fills the gap in the field of functional verification.
