Abstract

A guiding system for positioning a target object, which is capable of guiding a user of a mobile device to the position of the target object comprises an wireless positioning device configured on the target object, a plurality of base stations configured around the target object, a positioning server, and an application software built in the mobile device. The wireless positioning device sends wireless broadcasting signal to the base stations. The base stations measure the intensities of broadcasting signal and then send the broadcasting signal and the intensities to the positioning server. The positioning server calculates a locating area of the target object according to the broadcasting signal and the intensities, and then sends the locating area to the mobile device. The application software displays the locating area of the target object to guide the user of the mobile device to the locating area.

Claims

1. A guiding system for positioning a target object, for guiding a user of a mobile device to a position of the target object, comprising:

a first wireless positioning device, configured on the target object for sending a first wireless broadcasting signal, wherein the first wireless broadcasting signal comprises an unique device identifier of the first wireless positioning device;

a plurality of wireless base stations, configured around the target object, wherein the wireless base stations comprise a wireless module respectively, and the wireless modules of the wireless base stations receive the first wireless broadcasting signal respectively and measure a first wireless radio signal strength of the received first wireless broadcasting signal;

a positioning server, recording the fixed positions of the wireless base stations, and establishing an Internet connection with the wireless base stations, wherein the positioning server receives the first received signal strength indication measured by the wireless base stations via the Internet connection, and identifies the target object that the first received signal strength indication belong to according to the unique device identifier of the first wireless broadcasting signal, and then calculates a distance between the target object and the wireless base stations according to the first received signal strength indication, and the positioning server calculates a positioning area of the target object according to the distance between the target object and the wireless base stations and the fixed positions of the wireless base stations and sends the positioning area to the mobile device via the Internet connection; and

an application software, wherein the application software is for displaying the positioning area of the target object on the mobile device to guide the mobile device to the positioning area;

wherein when the mobile device enters a signal range of the first wireless positioning device, the mobile device receives the first wireless broadcasting signal and calculates the distance between the mobile device and the target object according to the first wireless radio signal strength.

2. The guiding system for positioning a target object of claim 1, wherein when the mobile device enters the signal range of at least one of the wireless base stations, the mobile device establishes at least one first wireless network connections with at least one wireless base station, and the positioning server calculates a distance between the mobile device and the wireless base station corresponding to the first wireless network connection via the wireless radio signal strength of the first wireless network connection and calculates a current position of the mobile device according to the distance and the fixed positions of the wireless base stations.
