Intercity and urban rail interconnection and intercommunication train control method and control system

The invention discloses an inter-city and urban rail interconnection and intercommunication train control method and control system, the method comprises basic train control logic and a control right handover method, and the control right handover method comprises the steps that a train is provided with an inter-city train control train-mounted system and an urban rail train control train-mounted system at the same time; when the train enters the urban rail line from the inter-city line, the control right is switched from the inter-city train control train-mounted system to the urban rail train control train-mounted system; the train enters the inter-city line from the urban rail line, and the control right is switched from the urban rail train control train-mounted system to the inter-city train control train-mounted system; and in the switching process, one of the inter-city train control vehicle-mounted system and the urban rail train control vehicle-mounted system sends handover request information to the
