Train screening method and system based on autonomous operation control mode

Abstract

The invention provides a train screening method and system based on an autonomous operation control mode, and belongs to the field of rail transit, and the method comprises the following steps: current train on-board equipment obtains axle counting state information from a turnout controller; the current train on-board device obtains position information of other trains from other train on-board devices and turnout controllers; and the vehicle-mounted equipment of the current train combines the axle counting state information and the position information of other trains to complete screening of the current train. In order to solve the problem that the efficiency of moving block tracking after the train is screened is reduced due to the fact that the existing urban rail transit train screening and judging function relates to multiple equipment links and the information transmission and judgment speed is low, the functions are redistributed, the combination of multiple mechanisms is realized, the communication transmission is reduced, and the efficiency of moving block tracking is improved. The method improves the autonomous judgment control capability of vehicle-mounted equipment, and can also be used for a train autonomous operation control mode.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a train screening method and system based on an autonomous operation control mode. Background technique [0002] With the rapid development of urban rail transit, fully automatic unmanned driving system and train autonomous operation control technology are becoming more and more mature, and have gradually become the development trend of urban rail transit. In the case of fully automatic unmanned driving system and train autonomous operation control, urban rail transit also puts forward higher requirements for the safety and efficiency of the signaling system, and the screening of trains is an important function of the signaling system. The signaling system is an important part of completing mobile block tracking and improving operational efficiency. [0003] At present, the urban rail CBTC system consists of four parts: central equipment (ATS), ground equipment (CI, ZC), ...

AI Technical Summary

Problems solved by technology

The on-board equipment is a passive receiving end, and from sending the train envelope to upgrading the train, there are many communication links and equipment, and the interface is complex, resulting in low efficiency of this mode

[0008] In the train screening process under the existing CBTC mode, the function involves many equipment links and the speed of information transmission and judgment is slow, which leads to a decrease in the efficiency of mobile block tracking after the train is screened, and cannot be used in the train autonomous operation control system and mode
