    • An elevator system (20) includes wireless communicating portions (40, 42a-42c) that communicate with each other to provide elevator cab (22) position information within a hoistway (24). In one example, a first communicating portion (40) is supported on the elevator cab (22) that generates a trigger signal that is received by a second communicating portion (42a-42c) at a selected position along the hoistway (24). The second communication portion (42a-42c) generates an ultrasound signal that is received by the first communicating portion (40). A characteristic of the received locating signal, such as the timing between the trigger signal and the receipt of the locating signal, provides position information regarding the cab within the hoistway.
    • 电梯系统(20)包括彼此通信以在电梯井(24)内提供电梯轿厢(22))位置信息的无线通信部分(40,42a-42c)。 在一个示例中,第一通信部分(40)被支撑在电梯轿厢(22)上,其产生在沿着井道(24)的选定位置处由第二连通部分(42a-42c)接收的触发信号。 第二通信部分(42a-42c)产生由第一通信部分(40)接收的超声信号。 接收到的定位信号的特征,例如触发信号和定位信号的接收之间的定时,提供关于在井道内的驾驶室的位置信息。
