Abstract

The invention discloses a motion state perception-based low power consumption positioning method and system. The method comprises the following steps: carrying out offline training and online positioning; providing a low power consumption positioning service through introducing an acceleration sensor, wherein the acceleration sensor is capable of capturing the vibration changes in the X, Y and Z directions caused by the motion of the user; calculating the motion state and position change of the user through massive sample training and a machine learning method; providing a low power consumption position service with a certain positioning error; opening a GPS to complete precise positioning when the positioning error exceeds a certain threshold. According to the motion state perception-based low power consumption positioning method and system, the acceleration sensor with low power consumption is used for completing most of the positioning, so that the overall positioning power consumption can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of GPS positioning, in particular to a low-power positioning method and system based on motion state perception. Background technique [0002] With the continuous development of the mobile Internet industry, location-based services have become an important indicator of mobile terminals, providing great convenience for positioning and navigation in daily life. [0003] GPS positioning mainly includes two parts: one is the user receiver, and the other is the GPS satellite constellation. The satellite constellation continuously broadcasts satellite signals, and the user receiver can calculate the current position after receiving more than 4 effective satellite signals. [0004] At present, wearable devices such as vehicle-mounted positioning systems, smart phones, smart watches, smart glasses, and smart bracelets all need to integrate positioning modules to provide location services. Usually, various products ...
