一种基于同步多主对等总线的通信系统

A communication system based on synchronization multi-master P2P bus

多主对等总线系统上数据冲突频率的大大增加,导致重要信息无法得到及时处理。为了解决这一问题,文章以典型的多主对等总线CAN总线为例,介绍了一种基于同步多主对等总线通信系统的设计方法,包括硬件设计和软件设计两部分,该方法的优点是仅在总线系统分配的时间段内发送数据,避免在总线上产生冲突,提高车载系统信息传递的可靠性。

The frequency of data collision is greatly increased on multi-master P2 P bus. It＇s made important information can＇t be treated timely once appears. In order to solve the problem, this paper taking CAN bus as an example, introduces a communication system based on synchronization multi-master P2 P bus. It includes hardware design and software design. This method can send data only in time segment on bus system. The excellence is to avoid collision on bus and improve message transfer reliability.
