The refurbishment of an escalator is usually linked with its design life as recommended by the manufacturer. However, the actual useful life of an escalator should be determined by its operating condition which is affected by the runtime, workload, maintenance quality, vibration, etc., rather than age only. The objective of this project is to develop a comprehensive health condition analytic system for escalators to support refurbishment decisions. The analytic system consists of four parts: 1) online data gathering and processing; 2) a dashboard for condition monitoring; 3) a health index model; and 4) remaining useful life prediction. The results can be used for a) predicting the remaining useful life of the escalators, in order to support asset replacement planning and b) monitoring the real-time condition of escalators; including alerts when vibration exceeds the threshold and signal diagnosis, giving an indication of possible root cause (components) of the alert signal.

翻译：电梯的翻新通常与其设计寿命相关联，而设计寿命由制造商建议。然而，电梯的实际使用寿命应取决于其运行状态，该状态受运行时间、工作量、维护质量、振动等因素影响，而不仅仅取决于使用年限。本项目旨在开发一套用于电梯的综合健康状态分析系统，以支持翻新决策。该分析系统由四部分组成：1) 在线数据采集与处理；2) 状态监测仪表板；3) 健康指数模型；以及4) 剩余使用寿命预测。研究结果可用于：a) 预测电梯的剩余使用寿命，以支持资产更换规划；b) 实时监测电梯状态，包括当振动超过阈值时发出警报并进行信号诊断，从而指示警报信号可能的根本原因（组件）。
