Embodiment Construction

[0035] For an indoor space, such as a shopping mall, there are functional areas such as shops, passages, cash registers, elevators, and entrances and exits. To use the method disclosed in the present invention to finely position the indoor space, it is first necessary to divide the indoor space (including entrances and exits) into several mutually independent areas. The coverage area of ​​each area can be large or small, and the boundary shape is different The number is limited, and the number is not limited. It is mainly determined according to the actual situation of the area, the purpose of positioning, and the accuracy of positioning. , entry area: Entrance1, Entrance2, Entrance3, exit area: Exit1, Exit2, Exit3; eg figure 1 shown.

[0036] A positioning source with a unique identification code is configured in each area including the entrance and exit. When a mobile terminal loaded with a positioning source identification algorithm is brought into any area, the mobile ter...

Abstract

The invention relates to an indoor positioning method for mobile intelligent equipment. The method comprises the following steps of: dividing an indoor space into a plurality of independent areas, configuring a positioning signal source with a unique identification code nearby the center of each area, wherein when the mobile terminal loaded with a positioning signal source recognition algorithm is held to enter any area, the mobile terminal identifies an identification code which corresponds to the area, the identification code is submitted to a background server through a wireless communication network, and the background server feeds the area information back to the mobile terminal through determination so as to finish positioning. The positioning signal source is an audio signal modulation device which can output assigned frequency, and each segment of audio signal transmitted in a transmitting period of the positioning signal source corresponds to each bit code of the identification code. The positioning area is subdivided, the positioning accuracy can be obviously improved, and common smart phones and tablet personal computers in the market can serve as the mobile terminal; and therefore, the method is suitable for popularization and low in cost.

Description

technical field [0001] The invention relates to an indoor audio positioning method with the participation of mobile smart devices, and belongs to the technical field of sound wave and ultrasonic positioning. Background technique [0002] In recent years, with the popularization of mobile smart devices such as smartphones and tablet computers and the rapid development of the mobile Internet, the era of indoor navigation has entered. Some technology giants such as Google, Microsoft, Apple, and Broadcom, as well as some world-renowned universities and research institutes are all researching indoor positioning technology. [0003] The commercialization of indoor positioning technology will bring a wave of innovation, and various applications based on this technology will emerge in large numbers, and its impact and scale will never be inferior to satellite positioning. We can imagine some common applications, such as using indoor positioning technology to quickly find escape exi...
