A system and method of measuring and diagnosing the ride quality of an elevator system, including (a) operating the mobile device to acquire ride quality data, (b) operating the mobile device to transmit ride quality data to an external computing device, (c) operating the external computing device to compare the acquired ride quality data to pre-determined system data to create performance data, (d) operating the external computing device to perform a ride quality diagnostics based at least in part on the performance data, and (e) operating the external computing device to transmit the ride quality diagnostics to the mobile device.

System and method of measuring and diagnosing ride quality of an elevator system

A structural health monitoring system is provided. The system includes a drive system having a first drive member a second drive memberoperationally connected to the first drive member, and a tension memberoperationally connecting the first drive member to the second drive member. At least one sensoris configured to monitor a characteristic of at least one of the first drive member and the second drive member. A processor, in communication with the at least one sensor, is configured to determine if the structural health of the tension member is compromised based on the monitored characteristic. The processor is further configured to perform a safety response action when the structural health of the tension member is determined to be compromised.

A method includes receiving, from a portable recording device, multiple recordings of sounds made by an elevator during operation of the elevator, the multiple recordings generated at different times. The method includes analyzing, by a sound analysis circuit, the multiple recordings generated at the different times to detect changes in an elevator characteristic over time and generating, based on detecting the changes in the elevator characteristic over time, a notification to perform an action on the elevator.
