Embodiment Construction

[0041] The core of the present invention is to provide a positioning method, device and system, which can be applied to a mobile terminal, and realize mobile positioning through the time series of the wireless signal strength received by the wireless terminal. Among them, the time series of signal strength (RSSI Time Series, referred to as RTS) is the mobile node in the process of moving, the received signal strength of the wireless network it is connected to changes with time, and the change of this signal strength is recorded , as a signal strength time series for mobile localization.

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of t...

Abstract

The invention discloses a positioning method which comprises the following steps: receiving a positioning request transmitted by a mobile node, wherein the positioning request contains signal intensity time sequence data of the mobile node, and the signal intensity time sequence data is data for representing the change of wireless signal intensity along with time when the mobile node moves; inquiring signal intensity time sequence target data matched with the data of the mobile node in a pre-established signal intensity time sequence map, wherein the signal intensity time sequence map is used for recording the signal intensity time sequence data of the detected mobile node on different road sections; determining positioning data corresponding to the target data as positioning data of the mobile node. According to the positioning method provided by the invention, on the premise of ensuring the mobile positioning accuracy, the energy consumption required for positioning can be reduced. The invention further discloses a positioning device and a system.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method, device and system. Background technique [0002] With the popularity of mobile terminals (such as smart phones, tablet computers, etc.), more and more location-based services (LBS) are applied to daily life. However, a key issue in LBS applications is the location of mobile nodes. [0003] The existing GPS positioning method has high energy consumption and reduces the use time of the mobile terminal. However, the traditional method of using base station positioning has low positioning accuracy. [0004] Therefore, it is very necessary to provide a positioning method with low energy consumption and high precision. Contents of the invention [0005] The purpose of the present invention is to provide a positioning method, device and system, aiming at solving the problems of high energy consumption and low precision of the existing positioning m...
