Positioning system and method of indoor mobile device

Abstract

The invention provides a positioning system of an indoor mobile device. The positioning system comprises three base stations, a mobile terminal, a signal processing module, a wireless transmitting module and a background server. The three base stations are used for periodically sending Bluetooth signals in a Bluetooth wireless transmission mode, and the Bluetooth signals comprise broadcast packets of mark information of the base stations and signal intensities. The mobile terminal comprises a receiving module, wherein the receiving module is used for receiving the Bluetooth signals and determining the mark information of the base stations and the signal intensities according to the content of the broadcast packets. The signal processing module is used for calculating the distances between the three base stations and the mobile terminal according to the signal intensities of the three base stations and determining position information of the mobile terminal according to the three-point positioning algorithm. The wireless transmitting module is used for transmitting the position information to the background server through a wireless communication network. The background server is used for selectively pushing service information to the mobile terminal according to information of the distances between the mobile terminal and the base stations. After accurate positioning is carried out, data can be accurately pushed, and therefore various kinds of applications such as position marketing can be achieved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an indoor mobile device positioning system and a method thereof. Background technique [0002] Positioning technology has always been one of the technologies that are keenly studied. The technology used for location services has been developed for several generations. GPS (Global Position System) global position system, which relies on 24 GPS satellites roaming in the air to provide global users with The location service system provides key information to a large number of people who need to locate their location, and solves the problems of field location determination and trajectory tracking. In recent years, the positioning technology of mobile phone base stations has made great progress. It takes advantage of the wide coverage in the city to push the positioning application in the city to practicality, especially the popularization of its terminal equipment - mobile phones...

Problems solved by technology

However, WLAN APs have a large coverage area, and the system can only roughly determine the user's location based on the location of the AP. The accuracy of the location of the user in this way is poor, often resulting in an error of 30 meters, and this positioning method depends on the accuracy of the AP's geographical location. , because many APs achieve wireless signal coverage for users through the indoor distribution system, the difference between the actual location of all users and the location of the AP is still relatively large
