Abstract: An elevator system includes a component adapted to perform a function, a sensor, and a control configuration. The sensor is configured to detect an operating parameter associated with the function. The control configuration is configured to receive a parameter signal from the sensor, and extract a predesignated feature from data associated with the parameter signal. The predesignated feature is then aggregated by the control configuration and machine learning is applied to determine a degradation level of the function associated with the predesignated feature.

Abstract: A monitoring system includes one or more detection devices, a communication device, and an analytics system. The one or more detection devices generate, at a conveyance system, one or more data streams describing the ride of the conveyance system, where the data streams include at least one of vibration data and audio data. The communication device transmits sensor data based on the one or more data streams. The analytics system receives the sensor data from the communication device and, based on the sensor data, determines a ride quality of the conveyance system.

Abstract: A method of operating an elevator or escalator system is provided. The method includes alerting a mechanic of a shutdown of a vehicle of the elevator or escalator system and providing data indicative of an occupancy condition of the vehicle to the mechanic so that the mechanic can execute, in any order, a verification of a no-occupancy condition, a switch of a mode of operation of the elevator or escalator system to a recovery mode and an inspection for faults. The method further includes initiating an overspeed (OS) switch reset routine in an event the mechanic confirms that an actuation of the OS switch is an exclusive cause of the shutdown and remotely triggers the OS switch reset routine accordingly.
