    • An elevator (20) associated within a hoistway (22) and having a speed and position detection system (62, 64, 70) is disclosed. The elevator (20) may include an elevator component (60) associated within the hoistway (22), an optical sensor (62) associated within the hoistway (22), an object (64) associated within the hoistway (22) in such a manner to be aligned in a path of the optical sensor (62), and a processor (70) operatively coupled to the optical sensor (62). The optical sensor (62) may be capable of emitting a signal (66) and receiving a reflected signal (68) of the emitted signal (66). The object (64) may have surface features (64a) that may reflect the signal (66). The processor (70) may be capable of processing the reflected signal (68) to provide an output indicative of a speed and position of the elevator component (60).
    • 公开了一种在井道(22)内相关并且具有速度和位置检测系统(62,64,70)的电梯(20)。 电梯(20)可包括与升降道(22)相关联的电梯部件(60),与井道(22)相关联的光学传感器(62),在井道(22)内相关联的物体(64) 在光学传感器(62)的路径中对准的方式,以及可操作地耦合到光学传感器(62)的处理器(70)。 光学传感器(62)可能能够发射信号(66)并接收发射信号(66)的反射信号(68)。 物体(64)可以具有可以反射信号(66)的表面特征(64a)。 处理器(70)可以能够处理反射信号(68)以提供指示电梯部件(60)的速度和位置的输出。
