8. The method for adding or deleting trains for the railway signal simulation practical training system as claimed in claim 7, wherein the step S1-3 of the trackside simulation module changing the train section status comprises the steps of:
step S1-3-1, the trackside simulation module receives the train adding and deleting command (2) and positions a train section corresponding to train related information contained in the train adding and deleting command (2);
s1-3-2, occupying pressure or clearing a corresponding train section according to the train adding or deleting type of the train adding or deleting instruction (2);
step S1-3-3, judging whether the occupying or leaving of the corresponding train section is successful; if successful, go to step S2-1; if the failure occurs, the process returns to step S1-3-1.
9. The method for train addition and deletion for a railway signal simulation practical training system as claimed in claim 8, wherein the step S3-3 of determining and processing the train feedback information 4 by the CTC interface module comprises the steps of:
s3-3-1, the CTC interface module reads the train section state in the CTC system module updated in the S2, confirms that the train section state is changed completely, and enters the step S3-3-2; otherwise, terminating the adding and deleting of the train;
s3-3-2, the CTC interface module receives train feedback information (4) transmitted by the external interface module, and the step S3-3-3 is entered;
step S3-3-3, comparing whether train window number information (5) contained in the train feedback information (4) is consistent with the train station ID and the train section name in the CTC module line configuration according to the CTC module line configuration file; and if the information is consistent with the information, the train number window information (5) is sent to the CTC system module, and the step S3-4 is carried out.
