Problems solved by technology

The accuracy of indoor positioning based on wireless communication and base station positioning is relatively low. The indoor positioning technology based on RFID, ZigBee and other technologies can satisfy users' static indoor high-precision positioning, but it is very difficult for dynamic indoor positioning.

Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] A mobile device indoor positioning method process includes:

[0037] Step 1: GeoServer publishes the map service and establishes the location fingerprint database; the specific method is as follows:

[0038] 1.1) Write the fingerprint data Tag into the NFC chip, Tag is used as the unique identifier of the fingerprint tag, which represents the unique element of the fingerprint tag, does not record any position information, and facilitates the repeated use of the fingerprint tag;

[0039] 1.2) In indoor scenes, deploy fingerprint tags;

[0040] 1.3) Publish the indoor map through GeoServer, and sample the fingerprint tags deployed, and obtain the coordinate position of the fingerprint tags deployed (λ A , l A );

[0041] 1.4) Establish a location fingerprint database, and in the fingerprint dat...

Abstract

The invention provides a mobile equipment indoor positioning method. By using the advantages of safety, high speed, great band width and low energy consumption of an NFC (near field communication) technology, position fingerprint data is stored into an NFC label; the mobile equipment reads the position fingerprint data in the label through a self-carried NFC chip; the position information of the current point of the user is obtained; the current position of the user is initialized; the advancing direction and the speed of the user are obtained in real time through a magnetic field sensor and an acceleration sensor of mobile equipment; obtaining the real-time position of the user according to the user initial position and the sensor data; the indoor positioning in the moving state is realized; tile map service issued by GeoServer is used for displaying the real-time position of the user in the tile map. The method has the advantages that the indoor positioning based on the mobile equipment sensor is realized; the advantages of high positioning precision, high real-time performance, convenient and fast operation and the like can be realized.

Description

technical field [0001] The invention relates to an indoor positioning method for a mobile device, in particular to an indoor positioning method based on NFC, a magnetic field sensor, and an acceleration sensor. Background technique [0002] When satellite positioning cannot be used in the indoor environment, indoor positioning technology is used as an auxiliary positioning of satellite positioning to solve the problem that the satellite signal is weak when it reaches the ground and cannot penetrate buildings, and finally locate the current position of the object. Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, Bluetooth, infrared, RFID, ZigBee and ultrasonic to form a set of indoor position positioning system, so as to realize the positioning of people, objects, etc. in the indoor space. location monitoring. The accuracy of indoor positioning based on wireless communication and base sta...
