The invention discloses an ultrahigh-speed magnetic levitation low-vacuum tube tunnel vacuum environment operation protection method and system, and the method comprises the steps: firstly, a vacuum pipeline monitoring system builds an air diffusion model based on the pressure intensity and the air velocity in a vacuum pipeline; and then, based on an air diffusion model, the central operation control system controls the train-mounted operation control system through the partition operation control system so as to control the operation state of the train. By the adoption of the method, the safety risk caused by leakage of the low-vacuum pipe tunnel is avoided, safety protection of the train in the vacuum pipe is achieved, the reliability of train operation in the vacuum environment is greatly improved, and train operation safety is guaranteed.

    本发明公开了一种超高速磁浮低真空管隧真空环境运行防护方法及系统,所述方法包括,首先,真空管道监控系统基于真空管道内的压强和空气流速,建立空气扩散模型;然后,中央运控系统基于空气扩散模型,通过分区运行控制系统控制车载运控系统以对列车的运行状态进行控制。采用上述方法避免了低真空管隧泄露所带来的安全风险,实现了对真空管道内的列车的安全防护,极大的提高了真空环境中列车运行的可靠性,确保了列车运行安全。
