An elevator system includes an elevator car, an elongate tension member operably connected to the elevator car and configured to move the elevator car within a hoistway, and an elevator car position measurement system. An elevator car position measurement system includes a pulse generator configured to transmit pulses along an elongate tension member; and a detector unit configured to receive the pulse from the pulse generator after the pulse has been transmitted along the length of the elongate tension member and to record the time at which the pulse is received. One of the pulse generator and the detector unit is arranged to move within the hoistway depending on a position of the elevator car within the hoistway such that a length of the elongate tension member along which the pulses are transmitted varies depending on the position of the elevator car within the hoistway. The elevator car position measurement system is configured to determine a length of the elongated tension member along which the pulse is transmitted based on the recorded time, and determine a position of the elevator car within the hoistway based on the determined length.
一种电梯系统,包括电梯轿厢、可操作地连接到电梯轿厢并且构造成在井道内移动电梯轿厢的细长受拉部件,以及电梯轿厢位置测量系统。电梯轿厢位置测量系统包括配置成沿细长受拉部件传输脉冲的脉冲发生器;以及配置成在已经沿细长受拉部件的长度传输脉冲之后接收来自脉冲发生器的脉冲并且记录接收到脉冲的时间的检测器单元。脉冲发生器和检测器单元中的一个布置成取决于电梯轿厢在井道内的位置而在井道内移动,使得脉冲沿其传输的细长受拉部件的长度取决于电梯轿厢在井道内的位置而变化。电梯轿厢位置测量系统配置成基于所记录的时间来确定脉冲沿其传输的细长受拉部件的长度,并且基于确定的长度确定电梯轿厢在井道内的位置。
