Abstract

The embodiment of the present invention discloses a method for determining a floor, including collecting m air pressure values ​​and n sets of wireless fidelity Wi-Fi information within a preset period of time; wherein, each set of Wi-Fi information includes the identification of the wireless access point AP Information and received signal strength RSS, m and n are integers not less than 2; determine the air pressure change rate according to at least two air pressure values ​​in m air pressure values; if the absolute value of the air pressure change rate is greater than the preset value, according to n groups Wi ‑Fi information determines the k APs that send n groups of Wi‑Fi information, and the n i RSS; k is an integer not less than 1, 1≤n i ≤n, 1≤i≤k; Get the respective floors of the k APs; according to the respective floors of the k APs and the corresponding n of the k APs i A RSS determines two candidate floors; the target floor is determined from the two candidate floors according to the air pressure change rate.

Description

technical field [0001] The invention relates to the field of indoor positioning, in particular to a method for determining a floor, related equipment and a system. Background technique [0002] With the popularity of portable electronic devices, users' requirements for real-time and accuracy of location information are increasing. At present, GPS (Global Positioning System, referred to as GPS, Global Positioning System) is widely used. Its shortcoming is that when the GPS receiver moves indoors, the signal strength is greatly attenuated due to the influence of obstructions, resulting in the impact of positioning accuracy and even Unable to complete the positioning process. In order to solve the above problems, a solution for indoor positioning is proposed. For example, a portable electronic device receives a Wi-Fi (Wireless Fidelity Access Point) sent by an indoor Wi-Fi AP (Wireless Fidelity Access Point, Wi-Fi AP for short). Access Point, referred to as Wi-Fi, wireless fi...
