Description

Bluetooth positioning system and method

The present invention relates to a Bluetooth positioning system and method, and more particularly to a Bluetooth application for performing a special application in a mobile phone having a Bluetooth module and a GPS module to provide a location for locating a Bluetooth signal transmitter. Positioning system and method.

People have lost their experience, or they are looking for someone or an item that they can't find. At this point, remote positioning technology will be needed to help find the item. Although there are commercially available wireless signal receivers and mini wireless transmitters, the user can place the mini wireless transmitter together with the item to be located, and the wireless signal receiver detects the mini. A signal from the wireless transmitter to determine the distance and orientation of the mini wireless transmitter from the item relative to the wireless signal receiver. However, this prior art does have a number of shortcomings, such as: at most, it can only determine the distance and orientation but cannot know the exact location of the mini wireless transmitter, and only provides a set of pre-paired mini wireless transmitters and wireless signal reception. Therefore, it is not easy to be widely used, and once it leaves the receiving range, it cannot provide positioning and the like.

In recent years, a number of positioning technologies have been developed, such as satellite navigation devices developed by the Global Positioning System (GPS) technology, and smart phones with built-in GPS positioning modules. Although the existing commercial GPS positioning module can provide positioning accuracy with an error range of 2m~30m, however, since the GPS satellite signal is easily obscured by objects, the existing GPS positioning module and its related Equipment has the disadvantage of not being able to operate indoors or under the ground. In addition to GPS positioning technology, there are currently Other conventional positioning techniques have been developed. For example, a mobile communication device located in a mobile communication system (for example, Global System for Mobile communication (GSM), etc.) can receive a plurality of mobile communication base stations by the mobile communication device. The signal information, together with a known geographical location data of the mobile communication base station, can calculate the possible location of the mobile communication device in a triangular positioning manner. However, the disadvantage of such a triangulation technique using a mobile communication signal is that the positioning error range is as far as 300 m to 5000 m, which is not suitable for accurate positioning operations. Another conventional positioning technology is to use some smart mobile phones with built-in GPS positioning module, which can perform GPS positioning when receiving good GPS satellite signals, and adopt wireless base station triangulation technology when GPS satellite signals are not received. To locate, however, it still cannot overcome the shortcomings of both the GPS positioning module and the wireless base station triangulation technology. In other words, once the GPS satellite signal is not received, the positioning error range of the smart phone with the built-in GPS positioning module will reach 300m~5000m.

In addition, neither the conventional GPS positioning module described above nor the conventional triangulation technology of the mobile communication device can perform the positioning operation of the module or the position of the device itself. For some remote location users who have their own location, such as but not limited to: users who are worried about the loss of pets, children or mentally handicapped people, or who are worried about the loss of vehicles or other valuables, would like to have a device. Or technology is the ability to position their pets, children, elders, vehicles or other valuables at any time. Obviously, the conventional GPS positioning module described above or the conventional triangulation technology of the mobile communication device cannot meet this requirement.

The main purpose of the present invention is to provide a Bluetooth positioning system and method, which can detect a Bluetooth signal transmission by executing a special application in a mobile phone with a Bluetooth module and a GPS module. When the device is within its communication range, the positioning data detected by the GPS module of the mobile phone is associated with the Bluetooth signal transmitter to provide a function for remotely locating the position of the Bluetooth signal transmitter. With this, The obtained positioning data will be the physical position of the Bluetooth signal transmitter rather than the relative distance between the Bluetooth signal transmitter and the mobile phone.
