Abstract:Escalators are special equipment, whose safety is closely related to the personal safety of passengers. Escalator status monitoring and early warning are predictive systems that ensure the safety of escalators. The system is composed of sensors, data collectors, and data analysis software, and adopts the principle of vibration analysis to realize fault warning and maintenance component guidance to prevent faults or accidents. This system was used in the Beijing MTR project. Through the analysis of typical cases in the project, the application and operation mode of the system are explained in detail, and combined with the use of Beijing MTR Line 6 and the Daxing Airport Line, the use of vibration analysis is verified. The effectiveness of the escalator condition monitoring and early warning system and its significance in actual engineering are analyzed.
Keywords:rail transit   escalator   vibration analysis   condition monitoring   early warning
