The embodiment of the invention discloses an elevator position detection method, an elevator position detection system and an elevator. The elevator position detection method comprises the following steps of controlling a radar sensor arranged at the top of an elevator shaft to emit a radar signal; acquiring an echo signal of the top of a elevator car output by the radar sensor to the radar signal; determining a target echo signal of a target reflector at a preset position on the top of the elevator car based on the echo signal; and determining a floor position of the elevator car based on thetarget echo signal. According to the elevator position detection method, the elevator position detection system and the elevator, the target reflector is only arranged at the preset position on the top of the elevator car, the space occupation on the top of the elevator car is small, and therefore, the operation of maintenance personnel on the top of the elevator car cannot be influenced, so thatthe problem of inaccurate elevator position detection caused by radar signal reflection only on the top of the elevator car in the prior art is solved, and the detection accuracy of the elevator position is improved under the situation that the original structure of the elevator car is not influenced.

    本发明实施例公开了一种电梯位置检测方法、电梯位置检测系统及电梯。该电梯位置检测方法包括:控制设置于电梯井道顶部的雷达传感器发射雷达信号;获取雷达传感器输出的电梯的轿厢顶部对于雷达信号的回波信号;基于回波信号确定轿厢顶部预设位置处的目标反射物的目标回波信号;基于目标回波信号确定电梯轿厢所处的楼层位置。本发明实施例仅在电梯轿厢顶部的预设位置设置目标反射物,其对于电梯轿厢顶部的空间占用很小,因而不会影响维保人员在电梯轿厢顶部的作业,从而解决了现有技术中仅靠电梯轿厢顶部进行雷达信号反射导致电梯位置检测不准的问题,实现了在不影响电梯轿厢的原有构造的情况下,提高了对于电梯位置的检测精度。
