A screening identification and movement authorization method suitable for multi-group mixed trains

Abstract

This application discloses a screening identification and movement authorization method applicable to multi-group mixed trains. The screening identification method includes: calculating the corresponding train length according to the train grouping information, and determining the train length as the length of the train to be confirmed ; Use the CBTC control area and the length of the train to be confirmed to determine the screening section of the mixed-travel train; use the officially allowed minimum train length on the current line and the screening section in front of the train to perform pre-screening processing on the mixed-travel train; If there is a hidden train, obtain the actual train length of the mixed train, and judge whether the actual train length is consistent with the length of the train to be confirmed; Perform post-screening processing. The application realizes safe and effective screening and identification of mixed trains, thereby avoiding safety accidents caused by possible wrong train formation information.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a screening identification and movement authorization method suitable for multi-group mixed trains. Background technique [0002] At present, rail trains may have many different configurations and marshalling methods, for example, 6-car or 8-car marshalling, etc. Different marshalling methods make the trains have different lengths. [0003] In order to ensure the safety of trains on the line, the CBTC signal system (CBTC, Communication Based Train Control System, automatic train control system based on wireless communication) can be used to confirm the formation information of the train, and it is necessary to check whether there is a train in front or behind the train. Hidden trains for screening identification. [0004] However, at present, the CBTC signal system is usually used to screen and identify fixed-group trains to confirm whether there are hidden train...

Problems solved by technology

[0004] However, at present, the CBTC signal system is usually used to screen and identify fixed-group trains to confirm whether there are hidden trains before and after the fixed-group trains, but it is impossible to safely and effectively screen and identify multi-group mixed trains, thereby seriously reducing the risk of confusion. Line safety of the line on which the train is located

Moreover, since the train formation information reported by the train to the ground CBTC equipment through its own on-board CBTC equipment may have errors, this will cause a deviation between the train length calculated by the ground CBTC equipment and the actual length of the train. These may have wrong train length information to authorize movement, and serious safety accidents are likely to occur
