摘　　要：为克服现有技术在双系热备切换上可靠性低的不足,深入研究一种应用于列车自动运行系统的双系热备切换方法。该切换方法首先进行本系逻辑单元与对系逻辑单元的主备系竞争,当本系逻辑单元或对系逻辑单元竞争为主系时,控制输出与通信,并输出主系状态信号。通过双系热备之间的切换实现主备系切换,无需增加倒切(管理)单元或功能类似倒切(管理)单元的设备,提升系统的可靠性、简化系统设计。In order to solve the problem of low reliability of the existing technology of dual-system hot standby switching,a dual-system hot standby switching method applied to automatic train operation system is studied.Firstly,the switching method performs the competition of main and standby system between the dual-system logic units,When a system logic unit of any a dual-system competes to be the main system,it controls the output and communication,and outputs the status signal of main system.By switching between the dual hot standby systems,the switching between the main and standby systems can be realized without adding the reverse-cut(management)unit or the equipment with similar functions as the reverse-cut(management)unit,thus the reliability of the system can be improved and the system design can be simplifi ed.
