摘要： A method of predicting deterioration in a brake system of a passenger moving system includes, placing at least one sensor within the passenger moving system such that the sensor is in communication with at least one of a main shaft of the passenger moving system, at least one movable panel of the passenger moving system, a motor of the passenger moving system, a control unit of the passenger moving system, or a gateway device. The method also includes activating the at least one sensor, performing data acquisition each time the passenger moving system is stopped, refining the acquired data, calculating a stopping distance of the passenger moving system, repeating the performing and refining steps over a specified time period, and triggering a command signal initiating a maintenance operation in response to the calculated stopping distance reaching a pre-determined threshold.

摘要： A method of predicting deterioration in a component part of a passenger moving system includes, activating at least one sensor in communication with the component part, performing data acquisition to acquire data from the at least one sensor, processing the data, repeating the processing step over a first specified time period, and triggering a command signal to initiate a maintenance operation and generating a predictive alert, both in response to the processed data reaching a pre-determined threshold.
