基于CAN的音频控制网络内部通信总线设计

Design of Inner Communication Bus in Audio Control Network Based on CAN

介绍了一种基于CAN总线的分布式音频控制网络的研究开发情况,实现了CAN总线与各模块的接口设计,制定出了相应的音频效果控制器内部通信协议。对RS232接口设备、RS232接口设备与CAN接口设备的联机使用和设计具有联网能力的音频设备具有重要意义。

This paper introduces a kind of audio control network based on CAN and implements the interface between the communication bus and the system＇s modules. It also brings forward communication protocol for audio effect control. The audio controller takes full advantage of the characteristic of the CAN bus. So the various modules can be configured neatly and expanded easily. The technique promotes the state of the audio device＇s network control performance, which is of great significance in the instrument with RS232 interface.
