The invention relates to a flat shunting operation hook planning system, which is in a modularized structure. Each module comprises a hook plan pattern automatic planning module, a parameter setting module, a train reception and starting module, a shunting operation simulation module, a shunting operation executing pushback and play-back module, an information dynamic inquiry and display module and an in-site operation mark module. A system formed by the modules is connected with a transportation management information system (TMIS) of the existing station, the data of the train list information after departure of a TIMS database can be automatically read and written, train units are clicked by a mouse on a lane chart and are dragged to the required position after the grouping by planning personnel according to station sending and taking operation tasks, and one batch of shunting operation plans can be planed and completed.
