Abstract

A communication device based on an audio interface, comprising: a data receiving channel connected to the left channel and / or right channel of the audio interface, receiving an audio analog signal, and outputting first communication data after converting and decoding the audio analog signal; a signal processing unit connected to the data receiving channel, reading and writing the inputted first communication data and outputted second communication data, and setting decoding and conversion parameters; a signal transmitting channel connected to the signal processing unit, converting the second communication data into an audio analog signal to be outputted to a microphone channel of the audio interface. In the scenario of asymmetrical data bandwidth requirements, with a combination of software technology and hardware technology, one or two audio channels can be used for transmitting communication data to improve the data communication rate, ensuring high speed communication data transmission and low bit error rate.

Description

technical field [0001] The invention belongs to the field of data communication, in particular to a communication device and method based on an audio interface. Background technique [0002] At present, data transmission devices based on audio interfaces basically only use one audio channel for data communication, and the communication rate is low; some use paired hardware codecs at both ends of the data channel, and the hardware cost is high; The software processing realizes the low-cost requirement, and the communication effect is not ideal. Contents of the invention [0003] Based on this, it is necessary to provide a communication device based on an audio interface with high transmission efficiency and low cost for the problems of low data transmission efficiency and high cost based on the audio interface. [0004] An audio interface based communication device comprising: [0005] The data receiving channel is connected to the left channel and / or the right channel of...
