摘要： Embodiments include a system and method for scheduling maintenance based on remote monitoring data and service data analytics. The embodiments include a controller configured monitor performance of one or more units, a remote system configured to store service data associated with the one or more units, and a processor operably coupled to the controller and the remote system. The processor is configured to receive monitoring data from the controller for the one or more units, and receive service data for the one or more units. The remote system is also configured to generate a health score based at least in part on the monitoring data and the service data. The processor is further configured to predict a failure based at least in part on the health score, and execute an action based at least in part on the generated health score.

摘要： 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.

摘要： An exemplary system includes a moveable mass. A load bearing member includes at least one electrically conductive tension member that supports a load associated with movement of the mass. An electrically conductive member is situated along a selected portion of a path of movement of the load bearing member. The electrically conductive member is not subject to a load on the tension member. A processor is configured to determine an electrical resistance of the tension member as an indicator of a condition of the tension member. The processor is configured to determine an electrical resistance of the electrically conductive member. The processor uses the determined electrical resistance of the electrically conductive member to compensate for any environmental influence on the determined electrical resistance of the tension member.

摘要： An electrical inspection system for an elevator load bearing member includes an electrically conductive, low resistance wrap located at the load bearing member, contacting the load bearing member around a circumference of the load bearing member. An inspection unit is configured to apply an electrical current through the load bearing member and determine an electrical resistance of the load bearing member, and is electrically connected to the load bearing member at the wrap to distribute electrical current uniformly therethrough. A method of determining an electrical resistance of a load bearing member of an elevator system includes applying an electrically conductive low electrical resistance wrap entirely around a circumference of the load bearing member. An inspection unit is connected to the load bearing member at the wrap. An electrical current is applied through the wrap into the load bearing member to determine an electrical resistance of the load bearing member.
