Method, system and equipment for realizing resource scheduling and train

Abstract

The embodiment of the invention discloses a method, a system, equipment and a train for realizing resource scheduling, and realizes message multi-transmission to an authorized node by simultaneously sending a target number of resource scheduling request messages to the authorized node through a request node. The authorization node can determine an authorizable time slot according to the received resource scheduling request message, and determine an authorization result according to the number of target time slots. And the authorization node simultaneously sends a target number of resource scheduling authorization messages to the request node. And if the request node does not receive the resource scheduling authorization message sent by the authorization node within the preset time, the target number is adjusted, and the sending of the resource scheduling request message is continued until the resource scheduling authorization message is received or the frequency of sending the resource scheduling request message reaches a frequency threshold. By adjusting the target number, normal transmission of messages between the request node and the authorization node is ensured, the success probability of direct communication between trains is improved, and normal operation of resource scheduling is ensured.

Description

technical field [0001] The present application relates to the communication field, in particular to a method, system, equipment and train for realizing resource scheduling. Background technique [0002] During the operation of the train, it needs to exchange information with other trains to ensure the normal operation of the train. [0003] At present, the communication between trains mainly relies on ground equipment for forwarding. When establishing a train communication network, it is necessary to consider the setting of ground equipment beside the track, which increases the construction cost and difficulty of the train communication network. However, if the method of direct communication between trains is adopted, although the cost of building ground equipment can be reduced, the communication process is easily affected by the operation of the train, and the quality of the communication link cannot be guaranteed. Therefore, how to ensure that relevant messages can be s...

When establishing a train communication network, it is necessary to consider the setting of ground equipment beside the track, which increases the construction cost and difficulty of the train communication network

However, if the method of direct communication between trains is used, although the cost of building ground equipment can be reduced, the communication process is easily affected by the operation of the train, and the quality of the communication link cannot be guaranteed.
