The invention discloses a train control system train-ground communication safety analysis method, system and device and a medium, and relates to the field of train-ground communication, and the method comprises the steps: setting the system-level danger of a train control system; constructing a train-ground communication control structure chart according to the information transmission route of each component in the train control system; the train-ground communication control structure chart is used for reflecting information flow among the components; analyzing a control behavior causing the system-level danger according to the vehicle-ground communication control structure chart to obtain an unsafe control behavior corresponding to the danger; and according to the unsafe control behavior corresponding to the danger, information flow in a vehicle-ground communication control structure chart is utilized to determine a cause scene. According to the invention, the system can comprehensively carry out safety analysis on the vehicle-ground communication of the CBTC system.
