signal opening module: checking whether signal opening conditions are met or not, and forming an opening instruction of a signal machine of a protection route when the signal opening conditions are met; after the signal is opened, continuously checking signal opening conditions, and keeping the signal open when the conditions are met, otherwise, closing the signal;
and the signal reopening module is used for: after the establishment of the access and the signal opening are successful, the signal is automatically closed after the signal interlocking equipment fails or has an operation error, the signal is restarted after the problem of manual confirmation is eliminated, and the signal is started if the signal interlocking equipment is recovered to be normal;
the automatic route unlocking module: after the establishment of the access way and the signal opening are successful, the signal interlocking equipment automatically unlocks or returns to unlock the access way after the vehicle enters, leaves or returns to clear the operation when the signal interlocking equipment is normal;
manual delay unlocking route module: after the automatic unlocking of the route fails, the route can be manually delayed to be unlocked after the unlocking is confirmed manually;
and manually cancelling the route module: after route selection, the change of the scheduling plan is confirmed by a person to cancel the route;
section fault unlocking module: the locking section can automatically unlock failure under the condition of equipment failure or wrong running, and the unlocking corresponding section is manually confirmed;
switch individual control module: the total positioning, total reversing, single interlocking, single turning, independent locking and independent unlocking operation control of the turnout equipment;
signal interlocking equipment card hanging and picking module: section, annunciator, turnout maintenance listing and picking.
9. The signal interlocking system for factory-area railway and train switching compatibility according to claim 4, wherein each functional module of the signal interlocking functional module is controlled by a centralized dispatching system or a manual dispatching system in a central interlocking control state;
and each functional module of the signal interlocking functional module is in a central turning control state, and the related signal interlocking equipment is processed and controlled by the logic controller of the lower equipment.
10. A method for interlocking a factory-area railway and a train-change compatible signal, which is characterized in that the factory-area railway and the train-change compatible signal interlocking system as claimed in any one of claims 1 to 9 is adopted for signal interlocking.
