Embodiment 1

[0061] Embodiment one, such as figure 1 Described, a kind of indoor positioning method based on WLAN comprises:

[0062] Step 1: The mobile terminal detects and receives the signal strength of the AP unit, and sends a positioning request signal to the server unit through the AP unit, and the mobile terminal is a mobile terminal with a WIFI function;

[0063] Step 2: The server unit receives and analyzes the positioning request signal sent by the mobile terminal through the AP unit, and feeds back the analyzed position information of the mobile terminal to the mobile terminal through the AP unit, and the mobile terminal displays the position information.

Embodiment 2

[0064] Embodiment 2: On the basis of Embodiment 1, the AP unit includes at least 3 wireless AP devices. In the step 1, the mobile terminal detects and receives at least 3 wireless AP devices with the strongest connection signal strength, and passes through any one of the wireless AP devices. The wireless AP device sends a positioning request signal to the service unit.

Embodiment 3

[0065] Embodiment 3: On the basis of Embodiment 1 or 2, the AP unit includes three wireless AP devices.

Abstract

The invention relates to the field of wireless network communication and particularly relates to a WLAN (Wireless Local Area Network)-based indoor positioning method and device. According to the WLAN-based indoor positioning method and device aiming at the problems in the prior art, the position of a mobile terminal can be determined after the mobile terminal sends a positioning request signal to a server unit through an AP (Access Point) unit, and furthermore, the fast positioning of an indoor position can be realized. The method comprises the following steps of: detecting and receiving signal strength of the AP unit by the mobile terminal, sending the positioning request signal to the server unit through the AP unit, receiving and analyzing the positioning request signal sent from the mobile terminal by the server unit, feeding analyzed position information of the mobile terminal back to the mobile terminal through the AP unit, and displaying the position information by the mobile terminal. The WLAN-based indoor positioning method and device are applied to the field of WLAN-based indoor positioning.

Description

technical field [0001] The present invention relates to the field of wireless network communication, in particular to a WLAN-based indoor positioning that utilizes Wi-Fi hotspots scattered throughout domestic airports, railway stations, libraries, government office buildings, and large shopping malls to provide positioning for indoor users Methods and devices. Background technique [0002] In modern information life, people's demand for indoor positioning is increasing day by day, and the requirements for system positioning accuracy are also getting higher and higher. When you are in a huge, complex and easy to get lost shopping mall, it is not easy to find a certain brand store, or to find a lost companion. At this time, if you can easily obtain relevant location information, it will make things easier. Much easier. Location information plays an important role in people's daily life. In unfamiliar environments such as suburbs, exhibition halls, and parks, the use of posi...
