1. a train bogie lateral stability detection method, is characterized in that, comprising:

  • Set up train operating data storehouse in advance;

    Described train operating data stock contains train operating data;

    The transverse acceleration of described train bogie framework is obtained by the acceleration transducer be installed on train bogie framework;

    Judge whether described transverse acceleration is greater than a secure threshold;

    If described transverse acceleration is greater than described secure threshold, send alarm command to Train Transportation Simulation System, and to the lateral acceleration data of described train operating data library inquiry a period of time;

    Described alarm command comprises a time of fire alarming;

    Described a period of time be apart from described time of fire alarming before and after a preset time range;

    Judge whether the transverse acceleration in the lateral acceleration data of described a period of time gradual change occurs or undergos mutation;

    If the transverse acceleration generation gradual change in the lateral acceleration data of described a period of time, then determine that the bogie at this acceleration transducer place is laterally unstable, and determine that described alarm command is valid data;

    If the transverse acceleration in the lateral acceleration data of described a period of time is undergone mutation, then determine that described alarm command is interfering data.
