Abstract

The invention provides a control method for a virtual connected high-speed train under the braking force failure of the tracking car, which is characterized in that: for a mild braking force failure, the deceleration control is performed on the first car, and a new automatic driving is generated during the coasting process The curve is used for the driving control of the remaining routes after deceleration. The tracking car outputs a new minimum tracking distance through the neural network model to adjust the tracking distance of the vehicle in front; After the train stops, control all the single trains ahead of the faulty car to stop. Adopting the control method of the present invention to control the virtual connected high-speed train under the condition of tracking car braking force failure can ensure the operation safety of the virtual connected high-speed train and minimize the impact on line operation efficiency.

Description

technical field

[0001] The invention relates to the technical field of transportation, in particular to a control method of a virtual continuous high-speed train under the braking force failure of a tracking vehicle. Background technique

[0002] With the improvement of the high-speed railway network and the increasing transportation pressure, the shortage of transportation capacity needs to be solved urgently. How to improve the efficiency of train operation control so as to improve the transportation capacity of rail transportation is particularly important. The virtual link technology refers to the cooperative operation mode of train groups in which multiple trains run at the same speed and at very small intervals through wireless communication without relying on physical connection between multiple trains. The virtual link technology can effectively reduce the interval of train running and tracking, and greatly improve the transportation capacity without changing the exi...

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the examples.

[0053] like figure 1 The virtual continuous high-speed train shown is composed of multiple single trains. The single train running at the front is recorded as the first train, and the single train after the first train is recorded as the tracking vehicle. ATO (Automatic Train Operation) module 1, communication module 2 and positioning module 3, the first vehicle is also provided with an on-board central control module 4 and a driving curve generation module 5, and the tracking vehicle is also provided with a tracking control module 6, braking force monitoring module 7 and neural network module 8;

[0054] The vehicle-mounted ATO module 1 on the single first vehicle is connected to the driving curve generation module 5, and the vehicle-mounted ATO module 1, the positioning module 3, the communication module 2 and the driving curve generation module 5 on the first vehicle are all co...
