Abstract
The invention provides a floor positioning system construction method, which comprises the following steps: S1, an air pressure nuclear floor positioning module construction step: S11, acquiring historical air pressure measurement data acquired when a plurality of users move on different floors in a target building, and preprocessing the historical air pressure measurement data to obtain an air pressure difference set, each air pressure difference value in the air pressure difference set corresponds to a difference value between an air pressure measurement value and a reference air pressure, and the reference air pressure is an initial air pressure detected at a target floor; s12, clustering processing is carried out on the air pressure difference set to obtain an air pressure difference kernel set, each air pressure difference kernel in the air pressure difference kernel set corresponds to one floor in the target building, and each floor corresponds to one floor in the target building; each air pressure difference kernel is obtained by clustering air pressure difference values between all air pressure measurement values in the corresponding floor and the reference air pressure; and S13, an air pressure core floor positioning module is constructed, and the air pressure difference core set is configured on the air pressure core floor positioning module.
