摘要
结合客户需求,通过热备硬件和软件冗余程序设计控制系统冗余方案。从热备硬件和冗余程序设计的角度分别分析了冗余系统的可靠性和系统主备站切换时间,实践证明冗余系统的可行性与有效性。
Combined with the needs of customers,through the backup hardware and software redundancy program designed control system redundancy scheme.From the angle of the backup hardware and redundancy program design,this paper analysis the reliability of redundant systems and the Master and slave station switching time respectively.Practice has proved that the feasibility and effectiveness of the redundant systems.
