Elevator system and operation thereof

摘要

An elevator system has an elevator car suspended on at least one synchronous belt driven by a drive driving a drive pulley in a non-slip manner, a distance measurement device measuring a travel distance of the belt at the drive pulley for determining a car position, a controller actuating the drive based on-stored stop location position values and a determined car position to stop the car at two or more stop locations, at least one position sensor disposed from the drive pulley and signaling the controller when the car passes a reference position, and a compensation device making a correction of the stored stop location position values with a correction factor based on the difference between the car position determined by the distance measurement device and the reference position as the car passes the reference position. Methods for operating the elevator system and initializing the controller are provided.

主权项

1. An elevator system, comprising
an elevator car suspended on at least one supporting means formed as a synchronous belt; a drive unit for moving the at least one synchronous belt and the elevator car with a driving pulley interacting in a slip-free manner with the at least one synchronous belt; a travel measuring device for measuring a movement of the at least one synchronous belt in a region of the driving pulley for determining a position of the elevator car; a controller activating the drive unit based upon stop position values stored in the controller and the determined elevator car position wherein the elevator car is stoppable at at least two stops; a position sensor sending a reference position signal to the controller when the elevator car passes a reference position during movement by the drive unit; and a compensating device correcting the stop position values in response to the reference position signal based upon a difference between the elevator car position determined by the travel measuring device and the reference position utilizing a correction factor which is dependent on the difference.
