Abstract:
A method for automatically dispatching an elevator 110 based on a user's location is provided. The method includes querying a device 104 to determine a user's source floor and confirming the user's source floor. The method also includes querying the device to suggest the user's destination floor based on a history of destination floors traveled to by the user; and confirming the user's destination floor.
Abstract:
A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords, strands or wires of the coated belt or rope. The initial electrical resistance is calibrated by repeating the measuring of initial electrical resistance and populating a database with the measured initial electrical resistance values. A true initial resistance is determined from the population of initial electrical resistances and subsequent measured values of electrical resistance of the one or more cords, strands or wires of the coated belt or rope.
Abstract:
A system 110 includes an input/output 113 unit for receiving a user request to call an elevator 101, 102 and a processor 111 for processing the user request to assign an elevator to the user 105. The processor performs one of a first assignment process and a second assignment process. The first assignment process includes determining whether a delay condition exists for delaying assignment of the elevator to the user 202, delaying assignment of the elevator to the user based on determining that the delay condition exists 203, and assigning the elevator to the user based on determining that the delay condition does not exist 204. The second assignment process includes assigning the elevator to the user and notifying the user of the assignment, determining whether an assignment change condition exists 206, changing the assignment to another elevator based on determining that the assignment change condition exists 207, and notifying the user of the assignment change 208.
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:
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.
Abstract:
A method (138, 140, 142) for monitoring brake torque of an elevator (100) having a motor (116) is provided. The method (138, 140, 142) may engage an elevator brake (126) for a predefined duration, determine a displacement of an output shaft of the motor (116) during the predefined duration, and generate an alert if the displacement exceeds a predefined threshold.
Abstract:
A system for monitoring elevator car travel includes a plurality of bi-stable sensors (12) traveling with an elevator car (10); a plurality of sense elements (20) positioned along a path of the sensors (12); the sense elements (20) causing the sensors (12) to assume one of a first state and a second state; wherein states of the sensors (12) define a zone code (30) identifying a zone corresponding to the elevator car (10) position, the zone code (30) being a gray code.
