Title: METHOD FOR DETERMINING FLOOR, RELATED APPARATUS AND SYSTEM
Abstract:
Disclosed are a method for determining a floor, a related apparatus and a system. The method comprises: acquiring m atmospheric pressure values and n groups of wireless fidelity (Wi-Fi) information within a pre-set duration, wherein each group of Wi-Fi information comprises identifier information about a wireless access point (AP) and the received signal strength (RSS), and m and n are integers not less than 2 (S401); determining an atmospheric pressure change rate according to at least two atmospheric pressure values among the m atmospheric pressure values (S402); if the absolute value of the atmospheric pressure change rate is greater than a pre-set value, determining k APs for transmitting the n groups of Wi-Fi information and ni RSSs respectively corresponding to the k APs according to the n groups of Wi-Fi information, wherein k is an integer not less than 1, 1≤ni≤n, and 1≤i≤k (S403); acquiring floors where the k APs are respectively located (S404); determining two candidate floors according to the floors where the k APs are respectively located and the ni RSSs respectively corresponding to the k APs (S405); and determining a target floor from the two candidate floors according to the atmospheric pressure change rate (S406).
