specific Embodiment

[0061] In the train autonomous control system based on vehicle-to-vehicle communication, the request and allocation of trackside resources is a key content. When trains A, B, and C are all running to the turnout P1 according to the operation plan of the ATS (such as Figure 4 shown), trains A, B, and C successively send applications for turnout P1 resources to the WRC (such as Figure 5 As shown in ), after WRC receives the application of the train, it will output the command to drive the trackside equipment to the OC according to the resource application, so as to realize the allocation of trackside resources. The detailed resource allocation process workflow is as follows Figure 6 Shown:

[0062] ①The trains apply to WRC for trackside resources according to the operation plan;

[0063] ②After receiving the resource application, the WRC makes a reasonable judgment on the resource application. If the resource application is illegal, it rejects the application. If the resourc...

Abstract

The invention relates to a train autonomous control system and a method based on train-train communication. The system comprises a train automatic monitoring system ATS, a target controller OC, a vehicle-mounted subsystem CC, a label reader subsystem, a query responder and a data communication system DCS. The automatic train monitoring system ATS is connected with the vehicle-mounted subsystem CC.Wherein the train-mounted subsystems CC of adjacent trains are in communication connection with each other, the control system also comprises a trackside resource manager WRC; the trackside resourcemanager WRC is respectively connected with the train automatic monitoring system ATS, the train-mounted subsystems CC, the target controller OC, the label reader subsystem and the query responder. Compared with the prior art, the invention has the advantages of reducing the transmission link of data information on the network, improving the operation efficiency of the system and the like.

Description

technical field [0001] The invention relates to a train autonomous control system and method, in particular to a train autonomous control system and method based on vehicle-to-vehicle communication. Background technique [0002] The trackside resource management and interval protection of the traditional urban rail transit CBTC (communication-based train control system) signal system center on the ground equipment, which informs the on-board equipment through train-ground communication interaction to ensure the safety of the train. The resource management and actual use in the traditional CBTC signaling system are not the same object, which leads to complex round-trip information interaction between devices and many links, which affects the efficiency of information transmission. At the same time, there are many trackside devices in the system, and maintenance and implementation costs relatively high. [0003] Recently, the train control system based on vehicle-to-vehicle c...
