摘　　要：本文在分析煤矿井下语音通信现状基础上,提出一种数字安全广播系统设计,该系统选用CAN总线作为数据传输方式,在音频压缩上采用一种新的音频压缩格式即Ogg Vorbis编码,并利用ARM芯片STM32F103对其进行工程实现。通过实验证明其音频还原力方面的优越性。Base on analysis of the status of coal mine voice communication, this paper propose a design of digital security broadcast- ing system. This system choose CAN bus as its way of data transmission, and select Ogg Vorbis as its audio encoding compression format, and we also make it engineering realization by using ARM chip named STM32F 103. At last, the superiority of the audio restore have been proved by experiment.
