摘　　要：控制器局域网络(CAN)是实时嵌入式系统中传输短报文的串行通信协议,其通讯最高速率可达1Mbit/s。CAN在传输实时数据中有大量的应用,但在传输音频流上并未普及。针对在CAN总线上除了发送报文同时开通音频信道而具有的优点,举例说明了在系统带宽上引入音频信道的效果。The controller area network (CAN) is a serial communications protocol for transmitting short control messages in real time embedded system and can operate at speeds of up to 1Mbit/s. There are numerous applications of CAN carrying real-time data. However CAN has still not become popular carrying voice streams. In addition to control information, a voice channel running on the same bus may have several advantages. This paper presents and illustrates the effects of introducing a voice channel on the system bandwidth.
