Multi-block mixed operation train screening recognition and mobile authorization method

Abstract

The invention discloses a multi-block mixed operation train screening recognition and mobile authorization method. The method comprises the steps of calculating corresponding train length according to train formation information, and determining the train length as train length to be confirmed; determining the screening zones of a mixed operation train according to a CBTC control area and the train length to be confirmed; conducting front screening on the mixed operation train by means of the minimum train length officially allowed on the current line and the front screening zone of the train; acquiring the actual train length of the mixed operation train and judging whether the actual train length is consistent with the train length to be confirmed if there is no hidden train in front; conducting rear screening on the mixed operation train by means of the rear screening zone of the train when actual train length is consistent with the train length to be confirmed. By the adoption of the method, safe and efficient screening recognition of the mixed operation train is achieved, and accidents caused by the probability of wrong train formation information are avoided.

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, or Communication Based Train Control System, an 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 are hidden trains in front of or behind the train. Screening for 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 tra...

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
