摘要
TCAN是基于CAN的时间触发的高层协议,具有确定性行为,因而适用于安全相关的场合。本文首先从参照时间、基本周期、系统信息阵、网络时间单元和全局时间五个方面对TTCAN协议进行分析,其后讲解了基于MCP2515的一个TTCAN协议Level 1节点的实现方案。
TTCAN is a time triggered protocol based on CAN. It exhibits a fully deterministic behavior and is suitable for the safety critical system. The paper firstly introduces; TTCAN protocol from time reference, basic cycle, system matrix, network time unit and global system time five parts. Followed that, an implementation of TTCAN Level 1 is presented, based on MCP2515.
