Train control method based on mobile authorization verification

A train control method based on mobile authorization verification, the method comprising:

• calculating, by a vehicle-mounted device, a first mobile authorization according to line data, trackside resource allocation and locking situation, and position information of a train in front;
• calculating, by a resource management unit (RMU) in a ground trackside device, a second mobile authorization according to the line data, the trackside resource allocation and locking situation, and the position information of trains in front and behind, and sending the second mobile authorization to the vehicle-mounted device;
• and
• comparing, by the vehicle-mounted device, the first mobile authorization with the second mobile authorization, and selecting a stricter one of the first and second mobile authorizations to control train operation;
• wherein the trackside resources comprise fixed resources and movable resources, wherein the fixed resources comprise section track zones and tracks and can be used by trains after being allocated, and wherein the movable resources comprise track zones with turnouts and can be used only when allocated and locked by the current train;
• and
• wherein calculating the first mobile authorization comprises searching forward from a position of the vehicle-mounted device's own train to determine an end point of the mobile authorization based on whether resources are occupied by other trains, and for unoccupied resources, based on whether the resources have been allocated to the current train and, if the resources are movable resources, locked by the current train.
