Problems solved by technology

[0006] However, the positioning technology using sound waves is only used for the three-dimensional space itself, and its applicability is poor.
[0007] For example, in various indoor areas such as department stores, shopping plazas, museums, and art galleries, it is difficult to develop and provide information provision of facilities or items using location information, mobility convenience, wayfinding, and facility inquiries, etc., because GPS signals cannot be captured Serve
[0008] In particular, in the case of using the intensity of radio waves generated by adjacent radio wave generators, the positioning system relying on radio waves has large errors and many influencing factors, so it cannot exert practical performance

Embodiment Construction

[0029] Hereinafter, a position information providing system using sound waves according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0030] "Indoor" explained below refers to various places including department stores, shopping malls, museums, art galleries, and movie theaters.

[0031] First, if figure 1 As shown, in the present invention, the node signal generators 10 are respectively fixedly installed in various places of the indoor I such as a museum or an art gallery. In addition, if figure 2 As shown, the portable location terminal 20 carried by the user (for example, a museum visitor, etc.) calculates its own current location to inform the user.

[0032] The portable location terminal 20 includes: a location terminal specially manufactured for applying the present invention and provided by rental;

[0033] Smartphones or tablet computers can be applied to the present invention by insta...

Abstract

The present invention relates to a position-data-providing system using sound waves, and more particularly, relates to a position-data-providing system using sound waves, whereby real-time notification can be given of the current position of a user in possession of a normal mobile device comprising a microphone and speaker or a specialist terminal by using sound waves of which the propagation speed is relatively slow in indoor areas where GPS signals do not reach such as shopping malls, museums and galleries.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of March 7, 2014, an application number of 201480027022.5, and an invention title of "A System for Providing Positional Information Using Sound Waves". technical field [0002] The present invention relates to a positional information providing system using sound waves, and more specifically, to a positional information providing system using sound waves that can use slow propagation Sound waves that notify the user of their current location in real time. Background technique [0003] Generally speaking, the positioning technology used to provide location-based services (LBS: Location Based Service) can be roughly divided into network-based methods that use the base station unit information of the mobile communication network, that is, RF to propagate environmental information, and GPS receivers. GPS positioning method. [0004] Although these methods are suitable fo...
