Dynamic de-braiding: the dynamic de-compiling means that in the normal running process of a train of virtual train (consisting of two or more trains of entity), the virtual train is de-compiled into two or more trains of entity by gradually expanding the distance between the entity trains to the outside of the minimum interval distance range of the normal tracking distance of the two or more trains of entity trains, and the normal blocking system tracking running process of each entity train is changed.
According to the method, the high-speed rail motor train unit is operated in a dynamic grouping mode through analysis of the operation requirements of the motor train unit, the grouping mode of the motor train unit is adjusted according to the travel places of passengers, efficient utilization of resources such as vehicles and accurate matching of passenger flow and traffic flow can be achieved, the method is an important means for achieving energy conservation, carbon reduction and efficiency improvement of high-speed rail operation and an important support for improving the travel ratio of high-speed rail traffic, higher-quality transportation service can be provided, and the method is a development direction of high-speed rail train operation control technology.
In order to ensure safety during running of the train, collision with the front car is avoided, and a certain safety distance L is required between the train and the front car. The requirements for the values among L under different blocking modes are inconsistent, namely the values among L are related to the blocking modes.

The distance between the trains can be obtained by using the difference between the coordinates of the front car and the coordinates of the rear car. In the method, all trains provide respective position coordinates for other trains in the group in real time in an ad hoc network communication mode, each train judges the distance and the relative position of the other trains according to the own position coordinates, and then an actual value for controlling the target L is determined according to system requirements.

Similarly, the C car and the D car also generate respective car control curves to control the running of the respective trains.
The method relies on ground center equipment, and each train must first receive a control command for communicating with which train, then can establish communication connection, and cannot form formation by itself. The train cannot directly obtain what kind of train is in the train in the group. Each train needs to calculate its own movement authorization in real time.

Each train of the method must first provide for communication with that train through the ground center control equipment before a communication connection can be established with the target train through the ground base station. Each train needs to calculate its own movement authorization in real time. Full line requires wireless coverage. A central facility needs to be set to manage all train positions, states, etc.
The prior art requires that the ground requires the provision of a train management center. Each train is required to be communicatively coupled to a designated train in accordance with commands provided on the ground.

Both the first train of the marshalling train and the independently operated train require ground center equipment to provide a movement authorization terminal. The function of autonomous management and autonomous networking of the train cannot be realized. If the ground center fails, the normal operation is not possible. High construction cost, numerous and complicated system, low reliability and high maintenance cost.
