Vehicle-to-vehicle communication traffic resource management method based on resource whiteboard

Abstract

The invention discloses a vehicle-to-vehicle communication driving resource management method based on a resource whiteboard, which includes the following steps: step S1, the OC opens up a resource whiteboard memory area in the memory, and divides it into a free list pool and a named resource whiteboard list according to the usage of the resource area , a whiteboard list of anonymous resources; step S2, after the OC is powered on, when the first train connects, the first train initializes all the driving resources in the OC to anonymous resources; step S3, when a new train is registered, the OC adds a new A named resource, after the train is deregistered or when the train communication is lost, it is moved into the anonymous resource; step S4, after the on-board controller successfully registers with the OC, the OC sends the named resource and the anonymous resource forward every cycle. In the present invention, even if the resource management algorithm and data interface of the on-board controller are upgraded, the OC does not need to be changed; whether the train leaves the OC or the communication is lost, the applied or occupied resources can be safely recorded without loss.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to the vehicle-to-vehicle communication traffic resource management technology. Background technique [0002] There are two schemes for the existing vehicle-to-vehicle communication traffic resource management. Scheme 1 uses OC (Object Controller, object controller or object controller) to manage traffic resources. All trains apply to OC for traffic resources, and OC records all Train sequencing and resource information. Option 2, resource management is completely performed by the train, resources are exchanged between trains, and OC does not participate in the interim at all. [0003] The technical defect of scheme 1 is that the interface coupling between the OC and the on-board controller (CC) is relatively serious, and modification by either party will cause modification by both parties. The technical defect of solution 2 is that since the train itself is a dynamic element...

Problems solved by technology

The technical defect of solution 2 is that since the train itself is a dynamic element, it is difficult to deal with the problem of how to transfer resources after the train leaves and the communication is lost
