摘　　要：基于CAN总线的语音通信目前属于一个新课题。由于CAN具有基于报文的寻址方式特点,可省略掉传统的交换主机。尝试一种实现方案,以声码器AMBE-2020作为语音处理部分,结合微处理器AT89C51和CAN控制器SJA1000构成主要硬件,结合软件接口程序。经实验证明,该方案完全可行,可为相关应用提供参考。The actualizing of audio communication system based on CAN bus is a new task. For CAN＇s addressing mode according to message, switching equipments can be omitted in the system. In the thesis, the scheme consists of vocoder AMBE -2020 used as audio- processedunit,microcoprocessor AT89C55 and CAN- controller SJA1000 as hardware, and interfaceprogram as software. The system solution is practicality proved by experiments,and can be for reference.
