Low power consumption positioning method and system based on proximity sensing and mobile base station

Abstract

The invention discloses a low-power-consumption positioning method and system based on adjacency sensing and a mobile base station. The low-power-consumption positioning method comprises the steps of user position acquisition, wherein the mobile base station GSM is used for inquiring an adjacent base station and calculating the current position of a user; adjacent device detection, wherein a mobile terminal periodically starts a Bluetooth sensor to scan adjacent devices and detect whether other Bluetooth devices exist around, and a pairing mechanism is started so that the mobile terminal can be automatically connected to the available Bluetooth device if the adjacent Bluetooth device is detected; position sharing, wherein the mobile terminal and the Bluetooth device each transmit the position information obtained last time through Bluetooth, positioning accuracy of the mobile terminal and positioning accuracy of the Bluetooth device are compared according to the positioning information, and the mobile terminal updates the positioning information if the positioning accuracy of the Bluetooth device is higher than that of the mobile terminal, otherwise the positioning information of the mobile terminal remains unchanged. According to the low-power-consumption positioning method and system, the low-power-consumption mobile base station GSM and the Bluetooth sensor are used for positioning, the frequency of using a positioning module can be reduced through a positioning sharing method, and therefore the overall positioning power consumption can be 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 proximity sensing and mobile base stations. Background technique [0002] Location-Based Services (LBS) is an important part of the mobile Internet industry, which has spawned continuous innovation and popularization of target positioning, tracking and tracking technologies and markets. At present, the positioning system based on GPS technology and the second generation of Beidou has been widely used in vehicle positioning and navigation terminals, smart phones and emerging wearable devices. [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, ...

Problems solved by technology

[0005] However, the power consumption of the GPS module and the Beidou module is very large, about 160mW, second only to the screen and 3G communication module in the smart terminal

Experiments have shown that smart phones can only provide continuous GPS positioning services for 5-6 hours, and the latest smart watches can only provide GPS positioning services for about 2-3 hours, which is difficult to meet the long-term positioning needs of users
