Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] See figure 1 , which is a structure diagram of an embodiment of the mobile terminal ultrasonic communication system of the present invention, which includes at least one ultrasonic generator 1 and at least one mobile terminal 2, and the ultrasonic generator 1 is set at a specific position for sending out pre-modulated ultrasonic waves , the specific location mentioned here refers to the place where the user needs to communicate or locate, and the ultrasonic waves emitted by the sound wave generator 1 carry pre-modulated data. Booths, etc., while the ultrasonic wave can carry data or ID used to represent the position such as distance, angle, or store, booth information, etc.

[0019] The mobile terminal 2 is used to demodulate the received ultrasonic wave and obtain the preset information in the ultrasonic wave. The mobile terminal 2 includes a microphone 3 an...

Abstract

The invention provides a mobile terminal ultrasonic communication system. The system comprises at least one ultrasonic generator and at least one mobile terminal, wherein the ultrasonic generator is arranged at a specific position for transmitting an ultrasonic wave with pre-modulated data parameters; the mobile terminal is used for demodulating the received ultrasonic wave and acquiring preset information; the mobile terminal further comprises a microphone and a demodulation module; the microphone is used for receiving the ultrasonic wave transmitted by the ultrasonic generator; and the demodulation module is connected with the microphone, and used for reducing waveform of the ultrasonic wave which is received by the microphone and demodulating the data preset in the ultrasonic wave. The mobile terminal ultrasonic communication system has the advantages of low cost, convenience in arrangement, high flexibility and high adaptability.

Description

technical field [0001] The invention relates to a communication system, in particular to a mobile terminal ultrasonic communication system and method. Background technique [0002] With the development of society, the scope of people's activities is increasing. This mobility and uncertainty bring market and challenges to mobile communications, and at the same time bring unlimited business opportunities for the development and expansion of location services. The so-called location service (LBS, Location Based Services), also known as positioning service, refers to a mobile service that determines the actual geographic location of the mobile user through the cooperation of the mobile terminal and the mobile network, thereby providing the location-related service information required by the user. A service form that integrates communication and navigation. At present, for ordinary users, GPS-based and radio-frequency tag-based are the two most commonly used positioning technol...
