Abstract

This paper discloses a switching method and a portable electronic device, which are used to solve the inability to accurately identify pedestrians and vehicles in the prior art, and effectively improve the accuracy of identification. The method is applied to a portable electronic device including a barometer and a sound sensor, and includes: acquiring air pressure data collected by the barometer and sound intensity data collected by the sound sensor within a preset time period, wherein the air pressure data includes n groups of collection times and air pressure value, the sound intensity data includes n groups of collection times and sound intensity values, the barometer and the sound sensor are collected synchronously, n is an integer greater than 1; it is determined that the air pressure data and the sound intensity data meet the preset conditions, Switch the first positioning algorithm to the second positioning algorithm or switch the first positioning technology to the second positioning technology.

Description

technical field [0001] The invention relates to the communication field, in particular to a switching method and a portable electronic device. Background technique [0002] Global Positioning System (English full name: Global Positioning System, abbreviation: GPS) is generally used in outdoor environments, and in indoor environments (for example, shopping malls or garages, etc.) is usually deployed based on Bluetooth Low Energy (English full name: Bluetooth Low Energy, abbreviation : BLE) or wireless fidelity (English full name: wireless fidelity, abbreviation: Wi-Fi) indoor positioning equipment, which is convenient for realizing positioning and navigation functions in an indoor environment. [0003] Because the Bluetooth signal strengths received by pedestrians and vehicles are different (the Bluetooth signal strengths received inside and outside the car are different). Therefore, positioning techniques or positioning algorithms for pedestrians are not fully applicable to...
