The invention relates to an elevator system (1) having an elevator car (3) and a laser distance-measuring device (21). The elevator car (3) can be moved along a travel path (13), which is delimited at the top by an upper boundary (17) and at the bottom by a lower boundary (19). The laser distance-measuring device (21) is configured to emit a laser beam (27) and to determine a distance to a position at which the laser beam (27) impinges on an object. The laser distance-measuring device (21) is mounted on the elevator car (3) and configured such that in a first configuration the laser beam (27) can be directed upward to the upper boundary (17), and in a second configuration can be directed downward to the lower boundary (19). As a result, a current position of the elevator car (3) can be determined in a redundant manner. Furthermore, in a third configuration, lateral distances to boundary marks (35) can be measured in order to be able to read out information that is codified by the boundary marks (35).
提出一种电梯设备(1),其具有电梯轿厢(3)和激光测距装置(21)。电梯轿厢(3)可以沿着行进路径(13)移位,该行进路径朝向上方由上边界(17)界定并且朝向下方由下边界(19)界定。激光测距装置(21)被配置为发射激光束(27)并且确定距激光束(27)打到物体上的位置的距离。激光测距装置(21)安装并配置在电梯轿厢(3)上,使得在第一配置中,激光束(27)可以向上指向上边界(17)并且在第二配置中可以向下指向下边界(19)。由此,能够以冗余的方式确定电梯轿厢(3)的当前位置。此外,在第三配置中,可以测量距边界标记(35)的侧向距离,以便能够读取由边界标记(35)表现的信息。
