Although redundancy design has been adopted by measure angle computer (MAC), but the switches between the host and the backup were by mankind which can’t catch up with requirement of system real time. This paper analyses the task of primary-backup switching and confirm the time of auto switching are system fault and communication interruption. It proposes a new strategy by using the characteristic of dual -network of MAC by which add fault status words in net send data bags and changes thenet send time series.This strategy doesn’t need change hardware and only last one frame data on switching process which great enhancing the reliability of MAC.
