摘　　要：针对煤矿井下语音通信系统现状,设计了基于开源协议栈CANFestival的语音通信系统,在硬件上选用AMBE-1000作为语音编解码芯片、STM32为主控、CAN作为物理层通信方式,在软件上应用FreeRTOS实时操作系统和CANFestival协议栈,实现了井下长距离、低码率、低失真度的语音通信功能。In view of the current situation of the voice communication system in the coal mine,a voice communication system based on the open-source protocol stack CANFestival was designed.The system used AMBE-1000 as the voice codec chip,STM32 as the main control,and CAN as the physical layer communication mode in hardware,and used FreeRTOS real-time operating system and CANFestival protocol stack in software to realize the voice communication function of long distance,low code rate and low distortion in the mine.
