基于冗余CAN通道的时间触发技术实现

Time-Triggered Technique Realized on Redundant CAN Channels

提出了一种基于冗余CAN通道的时间触发技术,保证了分布节点的时钟在其通信通道失效的前提下仍能保证时钟同步,而不需要额外的电子装置。使用该技术可同时获得较高的带宽利用率,抑制不一致的消息重复率,可应用于需传输大量周期数据和少量非周期数据的分布式安全关键系统。

The paper presents a redundant CAN channels based on time - triggered technique. Clock on the distributed nodes remain synchronized in the event of failures in the underlying communication channels ,without the need for expensive or added interface electronics. When using this framework with redundant channels, the higher bandwidth usage can be achieved, the probability of inconsistent message duplicated can be controlled. The method is suitable for safety - critical distributed system in which much periodical data exchange and a few of non - periodical messages are required.
