Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 2 It is a schematic structural diagram of the system of the present invention. In this embodiment, the indoor environment is divided according to regular hexagons, wherein the circumscribed circle of each regular hexagon is the Bluetooth node signal coverage area, and in each regular hexagon Arrange Bluetooth nodes at the center and vertices, and set the Bluetooth nodes as slave devices. The ID information of each Bluetooth node includes identification information and location information, and the Bluetooth device of the mobile phone terminal is set as the master device; in addition, the AP is arranged according to the coverage of the AP node. The access point ensures that the mobile terminal can successfully connect to the AP node when working in the system; the mobile client software connects to the AP node through WiFi to ...

Abstract

The invention discloses a Bluetooth based indoor positioning service system and a Bluetooth based indoor positioning service method, and belongs to the technical field of indoor position positioning. The method comprises the steps as follows: step I, connecting a mobile phone with indoor Bluetooth nodes and an AP node through a client side, and uploading ID information of the Bluetooth nodes which can be connected with the mobile phone to a server through the AP node; step II, converting the received ID information of the Bluetooth nodes into corresponding position information by the server; step III, marking the position information in the corresponding position of an indoor map, and displaying the position information on the mobile phone client-side software. Compared with the conventional indoor positioning system, the system and the method change nothing on a mobile phone with a built-in Bluetooth chip, greatly reduce the requirements on the Bluetooth nodes, and give full play to the capabilities of a mobile terminal and a server, so as to enable the positioning system to be more stable, and enable upgrade and extension of applications to be performed conveniently.

Description

technical field [0001] The invention belongs to the technical field of indoor position positioning, and relates to a bluetooth-based indoor positioning service system and method. Background technique [0002] With the development of cities, giant skyscrapers are everywhere, and even when you are wandering in a large shopping mall, it is very likely that you will not be able to find the north and south. Complex buildings embody the crystallization of modern technology, which brings convenience to people's life, but also brings inconvenience. How to walk the road is a problem that occurs every day. Therefore, indoor positioning technology is receiving more and more attention. Pay attention to. [0003] At present, the methods of indoor positioning mainly include: radio frequency identification, ultrasonic, ultra-wideband, Bluetooth, WiFi, Zigbee, etc., but most of the methods cannot be directly applied to mobile phones, and must be realized through special handheld devices, w...
