Embodiment Construction

[0025] The WiFi-based indoor hierarchical positioning system of the present invention includes:

[0026] The Receive interface is used to obtain the wireless signal strength of the AP and the MAC address information of the AP transmitted by the mobile terminal user;

[0027] A judging module, configured to judge the floor where the mobile terminal user is located according to the information obtained through the Receive interface;

[0028] The positioning module is used to finally determine the position of the mobile terminal user on the floor according to the floor where the mobile terminal user is located, and using a position-based fingerprint recognition positioning method;

[0029] The display module is used to display the specific location of the mobile terminal user on the floor.

[0030] For the above-mentioned WiFi-based indoor hierarchical positioning system, its specific implementation method, see figure 1 , figure 2 and image 3 shown, including:

[0031] The...

Abstract

The invention discloses a wireless fidelity (WIFI) based layered positioning system and an implementing method. The system comprises a receiving interface, a judging module, a positioning module and a display module. The implementing method of the system includes firstly, acquiring wireless signal intensities and a media access control (MAC) address of an access point (AP); secondly, judging a storey where a mobile terminal user is located; thirdly, positioning the mobile terminal user; and fourthly, displaying a specific position of the mobile terminal user on the storey. According to the WIFI based layered positioning system and the implementing method, indoor layered mobile terminal users can be timely and accurately positioned, reference points are expanded by means of participation of the users, costs are saved, and simultaneously, accuracy of positioning can be guaranteed.

Description

technical field [0001] The invention relates to a positioning system and an implementation method, in particular to a WiFi-based layered positioning system and an implementation method. Background technique [0002] The location information of the target plays an important role in various occasions, such as vehicle navigation, personnel positioning in mines, construction site management, etc. GPS (Global Positioning System, Global Positioning System), as the most widely used satellite navigation and positioning technology in the world, has been popularized and applied in many fields. However, its signal is easily interfered and blocked by obstacles, and its positioning is unreliable or even invalid in dense urban areas, tunnels, indoors and other environments. With the maturity of IEEE802.11 (wireless local area network standard) technology, WiFi (Wireless Fidelity, wireless fidelity) is popularized all over the world, and its coverage is getting wider and wider. WiFi main...
