SPEED AND POSITION DETECTION SYSTEM

摘要

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).
