Document Type and Number:
WIPO Patent Application WO/2021/190145
Kind Code:
A1
Abstract:
Provided are a station identifying method and device, a terminal and a computer-readable storage medium, belonging to the field of artificial intelligence. The method comprises: in response to being in a subway mode, collecting ambient sounds by means of a microphone (101); carrying out feature extraction on the ambient sounds to obtain energy features of the ambient sounds (102); according to the energy features, determining a running state of a subway, the running state comprising at least one of an inbound state, a stopped state, an outbound state and an inter-station traveling state (103); and in response to that the running state is the stopped state, determining a current station according to a currently registered base station (104). The method uses the characteristic that the energy features of sounds in different running states of a subway are different to determine the running state of the subway, and when the subway is in a stopped state, uses a currently registered base station to identify and update a current station, thus determining a station without using a complex model to acquire station reporting voice or third-party data, and having low power consumption and high accuracy.
