Three, interconversion of resource management and route management
The resources and the access paths are different management modes of the TACS system and the backup train control system for the resources occupied by the train operation, and the essence of the management modes is to distribute and mutually exclusive detect the corresponding resources, so that the conflict caused by the fact that different trains occupy the same resources is avoided. In the TACS system, resources must be hooked with train cars in the same time, so that resource management and route management are facilitated, and route management is also facilitated. Thus, the resources of the TACS system are allocated to a specific train, and the train is also required to release the resources; the automatic routing in the manual mode is required to be performed for a specific train, and if the train cannot be specified temporarily, the train attribute of the route needs to be clarified when the train approaches. Resource management and route management are substantially the same, and the interconversion of the resource management and the route management is the basis for the compatibility of the TACS vehicle control mode and the backup vehicle control mode.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.

the trackside dispatching equipment is connected with the control center and used for processing relevant automatic route handling commands and manual operation and reporting the route status.
14. The method for implementing the backup vehicle control mode for the TACS system according to claim 13, wherein the resource management process of the resource management module, the interlocking train control process of the interlocking train control module, and the trackside scheduling manual intervention process of the trackside scheduling device are run in parallel.
15. The method as claimed in claim 13, wherein the interlocking train control module performs processing of train route command and manual operation command, including automatic handling of the route, manual establishment and cancellation of the route, corresponding checking and giving an error alarm.
16. The method of claim 13 wherein said interlocking train control module performs manual fault handling including section fault unlocking of trains, total station unlocking and manual confirmation of train position.
17. The method of claim 13, wherein the interlocking train control module sends a resource application and cancellation command to the resource management module, and sends route, lock, and train occupancy information to the trackside scheduling device.
18. The method for implementing the backup train control mode for the TACS system according to claim 13, wherein the interlocking train control module tracks the state of train route in real time according to the resource state and the track circuit occupation status given by the resource management module to determine the state of the traffic signal.
19. The method for implementing the backup train control mode for the TACS system according to claim 13, wherein the interlocking train control module implements control over a target controller through a resource management module, controls a switch position, a signal and a trackside electronic unit, and obtains information on the switch position, the signal and a track circuit state.
20. The method as claimed in claim 13, wherein the interlocking train control module performs information tracking in the backup mode when the trackside equipment RMU is in normal communication with the train and in the TACS control mode, and immediately occupies the allocated resources of the train when the train loses communication or is in the manual control mode.
