Problems solved by technology

[0002] With the continuous development of society, the speed of urbanization began to accelerate, and more and more cities began to build underground vehicles (such as subways), but compared with the indoor environment on the ground, the urban underground vehicles (such as subways) The environment is relatively closed, and wireless signals are relatively scarce, so it is difficult for electronic devices (such as wearable devices) located in underground vehicles to collect the required mobile signals, and thus electronic devices cannot achieve accurate site positioning

Abstract

The embodiment of the present application relates to the field of positioning technology, and discloses a station positioning method of an underground vehicle and an electronic device. The method includes: detecting whether the movement speed of the underground vehicle where the electronic device is located has decelerated to a first specified threshold; wherein, The first specified threshold is greater than zero; if so, acquire the voice announcement information played by the underground vehicle; identify the next station of the underground vehicle from the voice announcement information. The embodiments of the present invention can improve the site location accuracy of electronic equipment located in underground vehicles.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a site positioning method and electronic equipment for underground vehicles. Background technique [0002] With the continuous development of society, the speed of urbanization began to accelerate, and more and more cities began to build underground vehicles (such as subways), but compared with the indoor environment on the ground, the urban underground vehicles (such as subways) The environment is relatively closed, and wireless signals are relatively scarce, so it is difficult for electronic devices (such as wearable devices) located in underground vehicles to collect the required mobile signals, and thus electronic devices cannot achieve accurate site positioning. Contents of the invention [0003] The embodiment of the present application discloses a method for locating a site of an underground vehicle and an electronic device, which can improve the accura...
