The invention relates to a system (40) and a method for determining the position of an elevator car (14) of an elevator installation (10), which elevator car (14) is movably arranged in an elevator shaft (12). The system (40) has a 3D-sensor (26), an evaluation unit (30) which is in communication with the 3D-sensor (26), and a marking element (36). The 3D-sensor (26) has a plurality of sensor units, and the evaluation unit (30) is configured to determine a distance of each sensor unit to a portion of an object detected by the 3D-sensor (26) by means of measurement data received from the 3D-sensor (26), said portion being detected by the sensor unit. The 3D-sensor (26) is arranged such that it detects the marking element (36) as an object in a normal mode of the system (40). The evaluation unit (30) is configured to determine the position of the elevator car (14) in the elevator shaft (12) on the basis of the distances from the sensor units (28) to the parts of the object detected by these sensor units (28), continuously perform a check whether the 3D-sensor (26) detects the marking element (36, 136), and, once the result of the above check is negative, determine the position of the elevator car (14) in the elevator shaft (12) on the basis of the distance from the sensor units (28) to the parts of the object detected by these sensor units (28). If so, the system (40) is brought into an error mode.
本发明涉及一种用于确定电梯设备(10)的可移动地布置在电梯竖井(12)中的电梯轿厢(14)的位置的系统(40)和方法。该系统(40)具有:3D‑传感器(26)、与3D‑传感器(26)保持通信的评估单元(30)以及标记元件(36)。3D‑传感器(26)具有多个传感器单元,并且评估单元(30)被配置用于,借助从3D‑传感器(26)接收到的测量数据来确定每个传感器单元到由3D‑传感器(26)检测的对象的由该传感器单元检测的部分的距离。3D‑传感器(26)被布置成使得:所述3D‑传感器在系统(40)的正常模式下将标记元件(36)作为对象加以检测。评估单元(30)被配置用于,基于从传感器单元(28)到由3D‑传感器(26)检测的对象的由这些传感器单元(28)检测的部分的距离,来确定电梯轿厢(14)在电梯竖井(12)中的位置,持续地执行检查:3D‑传感器(26)是否检测到标记元件(36、136),并且一旦上述检查的结果是否定的,就使系统(40)进入错误模式。
