摘　　要：提出一种基于双机热备份的设计方法,采用双机热备份主从工作模式,并通过一定的表决算法,模拟实现双机热备的全双工工作模式。从故障检测、控制表决、数据同步、监听值守等方面进行双机热备设计,在不增加硬件的基础上,尽可能地提高系统可靠性,保证系统的不间断运行。经验证,在主控计算机功能全部或部分失效时,备控计算机能够快速、“无缝”地进行功能控制。A design method based on dual-machine hot standby is proposed.The dual-machine hot standby master-slave working mode is adopted,and a full-duplex working mode of dual-system hot standby is simulated by a certain voting algorithm.The two-machine hot standby design is carried out from the aspects of fault detection,control voting,data synchronization and listening guard.On the basis of not increasing hardware,the system reliability is improved as much as possible to ensure the uninterrupted operation of the system.It has been verified that the standby computer can perform function control quickly and"seamlessly"when all or part of the main control computer functions fail.
