Audio sending and receiving terminal, and method for sending and receiving target data

Abstract

The invention discloses a method for sending target data. The method for sending the target data includes: encapsulating target data into long message formatted data with a preset data length; decomposing the long message formatted data into a plurality of data packages with equal data lengths, adding package head information to the front end of each data package, and adding package tail information to the rear end of each data package, wherein the package head information is provided with package numbers which are arranged in order, and the package trail information is checking information; modulating the plurality of data packages to at least two different sound wave carrier wave frequencies to form at least two pieces of audio data; and performing audio playing on the at least two pieces of audio data through an audio player. The invention also discloses a method for receiving the target data, an audio sending terminal, and an audio receiving terminal. According to the invention, the method for sending and receiving the target data can effectively improve the communication success rate of the target data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a target data sending method and an audio sending terminal applying the method, a target data receiving method and an audio receiving terminal applying the method. Background technique [0002] At present, acoustic wave communication systems have been widely used in various fields, such as identity authentication systems, acoustic wave payment systems, and audio recognition systems. In the acoustic wave communication system, the target data is received by the audio receiver, then the target data is processed, and finally the target data is sent out through the audio player, so that identity authentication, payment or audio recognition can be performed through the target data. [0003] However, in the acoustic wave communication system, the generally adopted acoustic wave carrier frequency is based on a single acoustic wave frequency carrier, and the data is modulat...

AI Technical Summary

Problems solved by technology

For a single acoustic wave carrier frequency, the target data is easily lost in the communication system. Once lost, the entire target data will be invalidated, and the target data transmission needs to be re-transmitted; in addition, due to the limitations of the acoustic wave communication system itself, the acoustic wave carrier frequency is too single , the target data is easily disturbed by the external environment, which directly affects the success rate of the target data
