摘要
管道声通信在一些特殊的场合存在一定的应用价值。设计并实现了一种智能、快速、低功耗的管道声通信系统。提出了一种声音混频编码通信的方法,设计了一套适用的、可靠的通信协议。系统设计过程包括硬件设计和算法软件设计两部分。以ARM处理器为处理核心,通过对不同频率的声音进行混频来编码,对混频信号进行快速傅里叶变换、峰值检测来解码。实验结果显示,系统可以迅速可靠地实现管道声通信。
Acoustic communication in pipeline has certain application value in some special occasions. This paper presents the design and implementation of acoustic communication system in pipeline, which is intelligent, fast, and low power consumption. System design includes two parts, hardware design and software design. The system uses an ARM processor to code signal by mixing sounds of different frequencies and to decode mixing signals by FFT and peak detection. Experimental results show that the system can achieve rapid and reliable acoustic communication in pipeline.
