The invention discloses a car position measuring method, device and equipment and a storage medium. According to the car position measuring method and device, the mapping relation of a first reference distance, a second reference distance and a third reference distance is established in advance; and the corresponding second reference distance is found from the mapping relation according to the target distance corresponding to the echo signal with the good signal-to-noise ratio to serve as the distance between the lift car and the top of the shaft, the lift car position measured through the phase method is corrected, accumulated errors generated by distance measurement through the phase method are eliminated, the lift car position accuracy is improved, and then safety is improved.
本发明公开了一种轿厢位置测量方法、装置、设备及存储介质,本发明预先建立第一参考距离、第二参考距离和第三参考距离的映射关系,在实际测量过程中,利用信噪比较好的回波信号对应的目标距离从映射关系找到对应的第二参考距离作为轿厢与井道顶部的距离,实现对相位法测量的轿厢位置进行修正,消除相位法测距产生的累积误差,提高轿厢位置准确度,进而提高安全性。
