摘    要:TTcan是基于标准CAN的高层协议.其提供一个全局时基来实现同步通讯,无任何总线仲裁器和总线主站。当TTcan总线空闲时,任何节点均可在特定的时间窗13内任意地传输消息。这有效地解决了由于工业智能设备的功能复杂化所带来的一系列影响总线传输安全性的问题。本文将对TTcan的特点和工作机制进行讨论。

关 键 词:时间触发  时间窗口  基本周期

Abstract:TTcan is a higher layer protocol based on the standard CAN. TTcan offer a global time to guarantee the synchronized communication. There is no arbitral controller or master on TTcan bus. If the TTcan bus is idle, any nodes could transfer their messages on it. TTcan protocol prescribes that any messages transmission must be done in Time Windows. These special points of TTcan could handle series problems in how to communicate safely when function & intelligence of devices using in Industrial field become more complex. This paper introduces the special points and the simple working mechanism of TTcan.
Keywords:TTcan
