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.
