摘要
研究煤矿井下的语音信号利用现场总线技术进行传榆的方法,同时介绍了多带激励语音压缩算法及利用CAN总线进行传输的优点,最后利用AMBE-2000语音压缩芯片和CAN控制器设计了一个语音通信系统。
In this paper, the method of transmitting voice signals in the coal mine with the fieldbus technology is studied. Then, the compression algorithm with multiband excitation voice and the advantage of transmission with CAN are also explained here. In the end, a voice communication system is designed by using the AMBE-2000 voice compressed chip and a CAN controller.
