Problems solved by technology
[0003] However, with the GPS positioning method, in indoor or underground spaces, the GPS signal will be affected, and there are positioning blind spots; with the base station positioning method, the positioning error will be very large in areas with weak signals or under the Yangtze River where the terminal moves at high speed, such as the underground railway. Large, sometimes over a kilometer

Embodiment 1
[0090] Figure 9 It is a schematic structural diagram of the positioning system in Embodiment 1 of the present invention, such as Figure 9 As shown, the system involved in Embodiment 1 of the present invention is mainly composed of the following system components: a Bluetooth positioning server, two or more Bluetooth adapters and a mobile phone terminal, wherein,
[0091] Bluetooth positioning server, composed of positioning server software, is mainly responsible for managing the Bluetooth adapter connected to the Bluetooth positioning server and the communication between the Bluetooth adapter and the mobile terminal, detecting mobile terminals entering the control area, statistics of data packet transmission and reception time, and Bluetooth signal strength detection , position calculation conversion, and marking the detected terminal position on the map of the current position.
[0092] The Bluetooth adapter is mainly responsible for communicating with the mobile phone ter...

The invention discloses a terminal positioning method, which includes: when a terminal accesses, a positioning server acquires the transmission speeds V1 and V2 from the first adapter to the terminal and from the second adapter to the terminal; The proportional relationship V / S between transmission speed and distance, and V1, V2, respectively obtain the distance S1' between the first adapter and the terminal, and the distance S2' between the second adapter and the terminal; according to S, S1 ' and S2' determine the relative positions of the terminals. The invention also correspondingly discloses a terminal positioning system and related devices. Because it is not limited to GPS signals, the present invention can avoid positioning blind spots. In addition, the present invention performs positioning based on the relative positions of the adapter and the terminal without referring to the signal from the base station to the terminal. Therefore, when the base station signal is weak In the scene where the area or the terminal moves at a high speed, it can also effectively perform positioning, and the positioning accuracy is high.
Description
technical field [0001] The present invention relates to the field of terminal positioning, in particular to a terminal positioning method, system and related devices. Background technique [0002] Terminal positioning refers to the technology or service that obtains the location information of the terminal or terminal user through specific positioning technology, and marks the position of the positioned object on the electronic map. According to the division of physical communication bearer channels, positioning technologies are generally divided into two types: one is positioning based on the Global Positioning System (GPS), and the other is positioning based on mobile operating network base stations. Among them, the GPS-based positioning method uses the GPS positioning module on the terminal to send the terminal's position signal to the positioning background to realize the positioning of the mobile phone; the base station positioning uses the measured distance between the...
