The invention discloses a nesting processing method of the continuous speed-limiting messages of trains, which concretely comprises the following steps of: initializing states and starting to receive speed-limiting messages; judging the states of the speed-limiting messages; and contrasting the current states of trains to output corresponding control. In the invention, continuous speed-limiting nested messages are processed by adopting an event-triggered state transition method, and the conversion among the four states is triggered by a T-mark event and a speed reduction-mark event; the invention has the advantages of high operating efficiency, high flexibility, strong expandability and the like and still can clearly judge the states of the speed-limiting messages under the condition of unknown number of layers; the control and the judgement on the running states of the trains are clear, and the conditions are definite, thereby avoiding the phenomena of unclear layer judgement, disordered control and the like caused by artificial reasons and assisting the drivers of the trains to pass speed-limiting sections at the optimal speed under the condition of ensuring the driving safety of the trains.
