摘要
车载控制器冗余热备是保证城市轨道交通信号系统可靠性的重要技术措施,主机和备机的选择和切换方案不同对设备性能有不同的影响。介绍了二乘二取二冗余和双机热备冗余中可采用的两种主、备机选择和切换方案,分析对比了两种方案的优缺点,以供选择方案时参考。
Hot redundancy of the on-board controller is an important technical measure to ensure the reliability of urban rail transit signal system. The selection and switchover schemes of the master and slave equipment have different effects on the equipment performance. In this paper,the two multiplied by two and two redundancy and the double machine thermal redundancy two main selection and switching methods are introduced,their advantages and disadvantages are compared and analyzed to provide a reference for the scheme selection.
