Problems solved by technology
However, the fixed sound wave frequency makes it impossible for the sender's terminal to communicate with other receiver terminals that cannot support the sound wave frequency, that is, the sound wave frequency cannot be independently adapted, resulting in poor compatibility between communication terminals. And the success rate of data transmission is low

The invention provides a communication method and system based on a sound wave transmitting and receiving terminal. The method comprises the steps that a first terminal enables the first frequency information of a receivable sound wave to be modulated and added to a first group of sound waves with at least two frequencies and then to be transmitted; a second terminal carries out the demodulation of the first group of sound waves through employing a preset specific second frequency; The first terminal enables the first frequency information to be modulated and added to a second group of sound weaves for transmission if the information of a first type and the first frequency information are not obtained through demodulation, wherein the second group of sound waves have at least two frequencies different from the frequencies of the first group of sound waves; and the first and second terminals carries out communication with each other through the first and second frequencies if the information of the first type and the first frequency information are obtained through demodulation. Through the above mode, the method and system enable the communication terminals based on the sound waves to achieve automatic matching of sound wave frequencies, improve the compatibility of data transmission between communication terminals, and improve the success rate of communication data transmission.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of audio data transmission, in particular to a communication method and system based on sound wave sending and receiving terminals. Background technique [0002] In the current life, compared with the traditional near-field communication technology, the technology of applying sound waves to data transmission between terminals has been widely used because of its high reliability, strong security, fast data transmission speed, and low cost. field of business communications. [0003] In the prior art, when performing data transmission based on sound waves, the terminals of the sender and the receiver must send and receive sound waves (sound waves) with corresponding fixed and known sound wave frequencies to establish a communication mechanism. However, the fixed sound wave frequency makes it impossible for the sender's terminal to communicate with ...
