Abstract: To improve the safety and reliability of maglev Automatic Train Operation (ATO) system , a feasible automatic control strategy was proposed. Based on two-unit redundant model of system architecture, communication handshake strategic was used to achieve system communication and role recognition; automatic control strategy was designed to ensure the correct implementation of operation plans. In order to verify the feasibility of the system，the failure rates were divided into several different parts. According to the effects of each part of the failure rate, this paper utilized Markov model to analyze the reliability and safety. A simulation analysis was performed and the result shows that the strategy is effective.

摘要： 为了提高磁浮列车自动驾驶系统的安全性和可靠性，提出了一种可行的自动运行控制策略。基于双机冗余模式的系统架构，采用设计的通信握手策略来实现系统通信及角色识别；通过运行控制策略来确保运行计划正确执行。为了验证系统的可行性，把单元失效率划分为一系列独立部分，根据各部分失效率对系统的产生影响，运用马尔可夫模型进行了仿真分析，结果表明该方案是有效的。
