Popis:	For limitations of broadcasting systems of traditional constant-pressure broadcasting, local amplified phone and personal handphone system, the paper proposed a design scheme of voice broadcasting system of coal mine based on Ethernet and CAN bus and introduced structure, design of hardware and software, key technologies of the system. The system can realize remote voice transmission at lower speed and streaming media online broadcasting, which adopts audio codec method of PCM and Ogg Vorbis and Ethernet and CAN bus to transmit data.
