Design and Implementation of On-Board Audio System's Source Node Based on INICnet

Abstract

In view of the fact that nodes in the current car audio system need to participate in network layer protocol analysis, which leads to difficult design and high hardware cost, this paper designs the source node of car audio system based on INICnet network, combined with the network characteristics of INICnet, the hardware of INICnet network. The interface realizes the structural design. The UNICENS centralized protocol stack is configured in the Linux operating system environment, and the data communication of the source node is realized by UTP unshielded twisted pair. The actual results show that the audio source node design based on the INICnet network completes the synchronous data transmission on the basis of the initial configuration of the peripheral circuit of the node, which provides the possibility of supporting high-speed packet data communication and reduces the hardware cost.
