TTCAN冗余网络的实现机制

Realization Mechanism of TTCAN Redundancy Networks

多条TTCAN总线通过TTCAN耦合可组成冗余网络。其网络同步层通过对相位差的调整获得相位同步,并采用对TUR(TimeUnitRatio)的调整获得速率同步。该TTCAN冗余网络的实现包括循环时间、全局时间的相位同步、速率同步等。

A series of TTCAN bus can establish redundancy TTCAN network by build TTCAN-coupled each other. Synchronization layer can obtain synchronization of phase by adjusting the difference of different bus. It can obtain synchronization of rate of clock by adjusting the value of TUR. The realization of the redundancy TTCAN network includes the cycle time, Synchronization of phase for global time, the synchronization of rate and so on.
