管道声通信是用于矿难发生时的一种应急通信，在有线和无线通信链路中断后可以作为应急通信的一种补充手段。但在以往的管道声脉冲信号编码中存在信息的传输效率低并且没有检错纠错能力的问题。这里提出了一种基于S模式信号格式的管道声脉冲信号编码方式，该方式能提高声信息的传输效率且具有检错纠错能力，在拥有上述优点的同时也没增加信号的编码复杂度，而且这种编码方式可以提高管道应急声通信的性能。

Pipe acoustic communication is an emergency communication which is used when mine accident occurs. When the wired and wireless communication link breaks,it can be used as an effective supplement means of emergency communica?tion. However,because previous coding of pipe acoustic pulse signal has problems of low transmission efficiency,and lacks of error detection and correction ability,a pipe acoustic pulse signal encoding method based on S mode signal format has been pro?posed in this paper,which can improve the transmission efficiency of signal,and meanwhile possess the ability of error detec?tion and correction. What′s more,this method doesn’t increase complexity of signal encoding and the performance of pipe acous?tic communication is improved.
