摘要
目前双总线间的仲裁机制主要分为总线切换和双收双发2种。总线切换技术开发成本高,所以双收双发机制也被很多人使用。在双收双发机制中,双通道数据不同步的现象客观存在,尤其当总线负载过大时,双通道数据不同步的现象明显,会带来命令误判,引起通讯异常。因此提出一种解决双通道数据不同步的算法,采用设置帧序号池的方法,解决了双冗余总线通讯不同步的现象,提高了双冗余总线通讯的可靠性。
There are two ways to achieve the communication of the dual redundant bus,bus switch and double transceiver.Because the cost of bus switch is high,so many systems use the double transceiver.Data unsynchronization exists sometimes in the system of double transceiver,especially in high busload,the data unsynchronization can increase greatly,which can lead mistakes in communication.The solution of Data unsynchronization is used the method of serial number pool,which can improve the product reliability.
