Train operation control system and method based on train-ground coordination

A train operation control system based on train-ground coordination, comprising a dispatching center server, a resource management unit RMU for ground train control equipment, and an on-board train control equipment CC, wherein the dispatching center server is connected via communication to the on-board CC, and the on-board CC is connected via communication to the RMU for the ground train control equipment;

• and
• the RMU for the ground train control equipment and the on-board CC coordinatively complete resource management and implement train operation control, wherein the resource management is divided into two levels, wherein at a first level, the RMU is responsible for performing the resource management in an unit of section, and at a second level, a preceding train and a succeeding train interact with each other via a direct train-to-train communication, such that finer resource sharing in a section is achieved between the trains,
• wherein the on-board CC is responsible for applying, using, and releasing line resources and turnout resources, for locking and unlocking turnouts, and for performing train-to-train communication with the preceding and succeeding trains to implement resource sharing,
• wherein the resource sharing between the on-board CC and the preceding and succeeding trains is completed by fine management of the line resources and the turnout resources,
• wherein with respect to section resources and the turnout resources, the preceding and succeeding trains directly perform position information interaction and mutual negotiation to subdivide an application range of the resources.
