APPARATUS AND METHOD FOR IDENTIFYING FLOOR ON WHICH USER IS LOCATED, BY USING BAROMETRIC PRESSURE AND MAGNETIC FIELD

WIPO Patent Application WO/2022/149906

A1

Disclosed are an identification apparatus and an identification method for identifying a floor on which a user is located in a building consisting of a plurality of floors. The identification apparatus comprises: a communication unit which receives first barometric pressure values measured by a plurality of barometric pressure measuring devices installed on the respective floors in the building, and a second barometric pressure value measured by a user terminal carried by the user; and a control unit which generates a converted value by converting the second barometric pressure value using a barometric pressure conversion equation corresponding to the user terminal, and identifies the floor on which the user is located by comparing the converted value with the first barometric pressure values. In addition, the control unit can more accurately identify the floor on which the user is located, by comprising: a first identification unit which identifies the floor on which the user is located, on the basis of a barometric pressure; a second identification unit which identifies the floor on which the user is located, on the basis of a vector sequence corresponding to the user's movement; and a third identification unit which identifies the floor on which the user is located, by using a trained artificial neural network.
