Abstract: Embodiments are directed to determining that an elevator car of an elevator system is approaching a landing, obtaining, by a controller, a value for at least one parameter associated with the elevator system based on the determination that the elevator car is approaching the landing, determining that the elevator car arrives at the landing within a threshold distance, determining, by the controller, when to engage in at least one of a brake cycling operation and a power cycling operation based on the value for the at least one parameter and based on determining that the elevator car arrives at the landing within the threshold distance, and initiating the at least one of a brake cycling operation and a power cycling operation at a time corresponding to the determination of when to engage in the at least one of a brake cycling operation and a power cycling operation.

Abstract: A system for releveling an elevator car floor with a landing floor includes a load weight sensor to sense a load weight of an elevator car at a landing floor, and a releveling controller operably connected to the load weight sensor to calculate a corrective velocity for the elevator car based on the load weight and estimates of the effective stiffnesses at the landing floor. A machine is operably connected to the releveling controller with both feedback and feedforward control and the elevator car to apply the corrective velocity to the elevator car thereby reducing a mismatch between the elevator car and the landing floor.

Abstract: An elevator system (100) includes an elevator drive system (101) including a tension member (103) supporting an elevator car (106) under tension and a monitoring system (102). The monitoring system includes a vibration sensor (111) for detecting vibration of at least one of the tension member and the elevator car and an analysis unit (112) for determining a level of wear and life of the tension member based on the vibration of the tension member detected by the vibration sensor.

Abstract: A system for determining stiffness of an elevator system tension member includes a landing floor indicator to transmit a landing floor signal of an elevator car to a stiffness estimator, and a car position encoder to transmit a car position signal of the elevator car in a hoistway to the stiffness estimator. A machine position encoder transmits a machine position signal to the stiffness estimator. The tension member is operably connected to the machine to move the elevator car along the hoistway. A load weight sensor is located at the elevator car to transmit a load weight signal of the elevator car to the stiffness estimator. The stiffness estimator utilizes at least the landing floor signal, the car position signal, the machine position signal and the load weight signal to calculate an estimated stiffness of the tension member.

Abstract: A structural health monitoring system is provided. The system includes a drive system having a first drive member a second drive member 38 operationally connected to the first drive member, and a tension member 39 operationally connecting the first drive member to the second drive member. At least one sensor 50 is configured to monitor a characteristic of at least one of the first drive member and the second drive member. A processor 54, 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.
