A locomotive wireless multi-heading remote distributed power traction operation control system. A set of differential multi-heading control unit () is added to a train control and management system of an original locomotive, and is combined and fused with a train control and management system (), a brake control unit (), a train safety monitoring device (), a locomotive logic control unit (), and a locomotive third-party device () to implement wireless multi-heading distributed power traction control operation of locomotives in a heavy haul combined train, and adapt to train multi-heading traction control operation of differential locomotives of a heavy haul combined train or multi-heading operation of different railway locomotives. Also provided is a multi-heading locomotive.

Locomotive wireless multi-heading remote distributed power traction operation control system, and multi-heading locomotive

Disclosed in the present invention are a heavy-haul train and a longitudinal dynamics traction operation optimization control system and method thereof. A model prediction function is added to a locomotive wireless double heading system so as to suppress large longitudinal impulse that is likely to be generated when the operation speed of the heavy-haul combined train is regulated, especially when the heavy-haul train is switched at a grade change point working condition, and the major potential safety hazard that affects the safe and stable operation of the heavy-haul combined train is avoided. In a distributed dynamic marshalling mode of the heavy-haul combined train, the requirements for the difference between the tractive force and the regenerative braking force of a master locomotive and slave locomotives of a multi-locomotive under the same working condition are predicted by the model, the amplitude of the power for the traction and the regenerative braking of the master locomotive and the slave locomotives is reasonably adjusted, and asynchronous control of the train under different working conditions is gradually achieved, so that the purposes of optimizing the dynamics performance of the heavy-haul combined train and reducing the longitudinal impulse of the heavy-haul train are achieved, and the operation of the train is guaranteed.
