A method according to claim 3, wherein in step S2, the area Z is calculated by the trackside resource controller WRC 2 The same area as the request of the vehicle-mounted controller CC; if the request area of the vehicle-mounted controller CC is empty, the area Z calculated by the trackside resource controller WRC 2 Is empty。
8. A method according to claim 3, wherein in the step S2, if two vehicles simultaneously apply for the same area resource, the trackside resource controller WRC allocates the resource to the train applying for the resource first, and then allows the two vehicles to negotiate the subsequent allocation of the resource.
9. A method according to claim 3, wherein in step S3, the trackside resource controller WRC checks M each time first_request If not, assigning the currently calculated area to the heavy education resource area Z 4 And M is taken up in first_request Set to 1.
10. A method according to claim 3, wherein in step S3, the train is at maximum V currentzone Taking the minimum value of the temporary speed limit, the permanent speed limit and the data configuration speed for the maximum running speed of the current area;
maximum effective time T of CC resource request of vehicle-mounted controller survival_time The maximum value between the reception of the Nth packet request message and the reception of the (n+1) th packet request message from the trackside resource controller WRC is included, and the maximum network transmission delay, the calculation delay of the vehicle-mounted controller CC and the calculation delay of the trackside resource controller WRC are included.
11. A method according to claim 3, wherein in step S3, the switch is encountered during calculation by the trackside resource controller WRC, and the zone Z is requested according to the onboard controller CC 1 And determining the turnout position.
12. A method according to claim 3, wherein in step S4, the resource zone Z 5 For realizing reasonable allocation of train resources beyond the resource zone Z 5 It is indicated that the train position information is erroneous and it is necessary to guide to the safety side, i.e. at this time it is necessary to initiate a re-education.
13. A method according to claim 3, characterized in that in step S7, a re-education request of the trackside train controller WTC is issued within a prescribed time.
14. A method according to claim 3, wherein said step S8 comprises two different cases: if the control right is switched, the weight education resource area is sent to a trackside train controller WTC; if the area check does not pass, it is sent to the in-vehicle controller CC.
15. An electronic device comprising a memory and a processor, the memory having stored thereon a computer program, characterized in that the processor implements the method according to any of claims 3-14 when executing the program.
16. A computer readable storage medium, on which a computer program is stored, characterized in that the program, when being executed by a processor, implements the method according to any one of claims 3-14.
