摘　　要：针对煤矿井下安全,提供了一种数字语音通信解决方案。该方案采用MBE压缩技术实现语音数据的压缩,并使用了STM32F107作为主控芯片,用主控芯片自带的CAN总线控制器实现远距离实时语音传输。文中介绍了该系统的软硬件设计,经测试,该系统在实际环境中具有良好的稳定性和实时性。A solution to digital voice communication is presented for coal mine safety. The MBE compression technology is used to compress the voice data, and the STM32F107 is adopted as the main control chip for real-time long-distance voice transmission base on the built-in CAN bus controller. The design of system hardware and software design is given. Tests in practical environment show that our design has good stability and real-time performance.
