Various embodiments relate to determining an elevator car position within an elevator shaft using footprint representations or descriptions of spectral data at reference locations along the elevator shaft. In one aspect, an example method is provided. The method includes determining reference spectral data for each of a plurality of reference positions along the elevator shaft, and generating a footprint associated with each reference position based at least in part on a plurality of frequency peaks within the reference spectral data for each reference position. The method also includes obtaining real-time spectral data associated with the elevator car within the elevator shaft, and determining an estimated position of the elevator car based at least in part on comparing the real-time spectral data to a plurality of footprints associated with the plurality of reference positions.
各种实施例涉及使用沿着电梯竖井的参考位置处的频谱数据的足迹表示或描述来确定电梯竖井内的电梯轿厢位置。在一个方面,提供了一种示例方法。该方法包括确定沿着所述电梯竖井的多个参考位置中的每一个的参考频谱数据,以及至少部分地基于每个参考位置的在所述参考频谱数据内的多个频率峰值生成与每个参考位置相关联的足迹。该方法还包括获得与所述电梯竖井内的所述电梯轿厢相关联的实时频谱数据,以及至少部分地基于将所述实时频谱数据与和所述多个参考位置相关联的多个足迹进行比较来确定电梯轿厢的估计位置。
