Design And Implementation Of Audio Intelligent Communication System

The use of audio as a carrier to spread information in life and scientific research is very little,but in a specific environment,audio communication have a unique advantage.In this paper,through the audio as a carrier,we made the communication goat in train air pressure pipeline.This paper focuses on the perfection process of the communication protocol.From the beginning of the time-domain transmission over long distances,and then,time-domain repeater transmission in short distances.Last,frequency-domain repeater transmission in short distances.this paper mainly take into account two factors are transmission distance and transmission efficiency in the design process of the whole communication protocol.System is applied to the LPC 1768 processor,the main function are listener,wake up,receive,judge,decode,encode transmit and so on.The system also has a good performance about fault-tolerant and anti-interference through continuous improvement algorithm.This system can work reliably in a terrible environment.At last,through the experiment,it is proved that this system is stable,efficient,low power consumption and intelligent.Audio communication scheme mentioned in this system,it design a complete communication protocol.This communication protocol has certain reference and application value...
