Provided is a position detection system capable of easily detecting the relative positions of a car and a maintenance worker. The position detection system (1) comprises a first air pressure measurement unit (17), a second air pressure measurement unit (20), and a detection unit (22). The first air pressure measurement unit (17) is provided on a lifted body-side device (13). The lifted body-side device (13) is mounted to an elevator (2) car (8) or a counterweight (9). The first air pressure measurement unit (17) measures a first air pressure in the elevator shaft (3) in which the car (8) travels. The second air pressure measurement unit (20) is provided in a terminal device (14) possessed by the maintenance worker (15). The second air pressure measurement unit (20) measures a second air pressure at the position of the maintenance worker (15). The detection unit (22) detects the relative positions in the vertical direction of the car (8) and the maintenance worker (15) on the basis of the difference between the first air pressure and the second air pressure.

    提供能够容易地检测轿厢与维护人员的相对位置的位置检测系统。位置检测系统(1)具备第1气压计测部(17)、第2气压计测部(20)和检测部(22)。第1气压计测部(17)设置于升降体侧装置(13)。升降体侧装置(13)安装于电梯(2)的轿厢(8)或对重(9)。第1气压计测部(17)计测轿厢(8)所行驶的井道(3)中的第1气压。第2气压计测部(20)设置于维护人员(15)所持有的终端装置(14)。第2气压计测部(20)计测维护人员(15)的位置处的第2气压。检测部(22)根据第1气压与第2气压的差异来检测轿厢(8)与维护人员(15)在铅直方向上的相对位置。
