The invention discloses a radar ranging method, device and equipment and a storage medium, a reflector is arranged at the end point of a hoistway, a car used for moving in the hoistway is provided with a radar, and the method comprises the steps that the radar is controlled to transmit an electromagnetic wave signal to the reflector and receive a first echo signal reflected by the hoistway; extracting a first frequency spectrum feature of the hoistway from the first echo signal; matching the first frequency spectrum feature with second frequency spectrum features learned from the hoistway in advance, wherein each second frequency spectrum feature is marked with a reflector; and if the matching is successful, the position of the lift car in the hoistway is measured according to the marked distance mapping of the reflector. Through the matching between the first frequency spectrum feature and the second frequency spectrum feature, the position of the lift car in the hoistway is measured, the interference caused by high-reflectivity obstacles such as metal objects can be reduced, the position precision is ensured, the position of the lift car in the hoistway can be normally measured no matter where the radar is powered on, and the safe operation of an elevator is ensured.

    本申请公开了一种雷达测距方法、装置、设备及存储介质,在井道的端点设置有反射器,用于在井道中移动的轿厢设置有雷达,该方法包括:控制雷达向反射器发射电磁波信号并接收经井道反射的第一回波信号;从第一回波信号中提取井道的第一频谱特征;将第一频谱特征与预先对井道学习的第二频谱特征进行匹配,每个第二频谱特征均已标注反射器;若匹配成功,则根据已标注的反射器的距离映射测量轿厢在井道中的位置。通过第一频谱特征与第二频谱特征之间的匹配,从而测量轿厢在井道中的位置,可以减少金属物等高反射率的障碍物造成的干扰,保证位置的精度,无论雷达在何处上电,均可正常测量出轿厢在井道中的位置,保证电梯的安全运行。
