Method and system for carrying out positioning on the basis of Bluetooth technology

Abstract

The invention discloses a method and a system for carrying out positioning on the basis of the Bluetooth technology. The method includes the following steps: Bluetooth access points broadcast own access point information, including ID (identity) information and coordinate information; on the basis of received signal strength RSSI, a mobile terminal sequences the surrounding Bluetooth access points according to the broadcast information of the Bluetooth access points; the mobile terminal transmits the chosen Bluetooth access point, the access point information and the sequence information to an application server; on the basis of the information of the Bluetooth access point, the sequence information and the access point information, the application server locates the position of the mobile terminal, and transmits positioning information to the mobile terminal; and the mobile terminal receives the positioning information, and displays the current positional information on the basis of a configured electronic map. After the invention is put into practice, indoor mobile terminals can be positioned by means of the Bluetooth technology, and therefore the defects of the GPS (global positioning system) and other satellite positioning systems, such as inaccurate indoor positioning, can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of Bluetooth positioning, in particular to a method and system for realizing positioning based on Bluetooth technology. Background technique [0002] At present, outdoor positioning systems include GPS in the United States, GLONASS in Russia, Beidou in China and Galileo in Europe. The use of satellite positioning outdoors has the advantages of wide coverage and large user access. However, when the user enters the room, the positioning accuracy of these positioning systems drops sharply. Mainly because of the influence of indoor barriers on the signal. Therefore, in order to solve the problem of indoor positioning, various indoor positioning systems and methods have been derived. [0003] The existing positioning method is to use infrared indoor positioning, which includes two infrared receiving bars composed of multiple infrared receivers, four infrared transmitters that send infrared detection signals in...

AI Technical Summary

Problems solved by technology

The limitation of using infrared positioning lies in the short distance of infrared and the straight line transmission of infrared; when the infrared is blocked by objects, its positioning effect is not very good, and when dealing with multiple moving objects; its performance varies according to the positioning algorithm used In addition, the local positioning device used in this method is a solidified device, so it is not possible to select, upgrade, and modify multiple positioning methods
