Blocking system and method based on train braking management

Abstract

The invention provides a blocking system and method, and belongs to the technical field of railway traffic management. The method comprises the steps of determining the event time of a train arriving at a geographic position event and the train braking functionality, and adopting train braking safety control according to the event time of the train arriving at the geographic position event and the train braking functionality. The system comprises a train and a data source, wherein the train is used for obtaining functional knowledge of train braking, receiving event time information sent by the data source on the ground and adopting safety control over train braking of the train according to the functional knowledge and the event time information; and the data source is used for generating event time information of a geographic position event when the train arrives at the data source and sending the event time information to the train. Near field communication signals are achieved, network space warfare of interval signals can be eliminated, the method can be conveniently applied to mountainous regions, canyons, long tunnel terrains, unmanned regions and land bridge regions, and small tracking train interval time operation of group trains can be conveniently achieved.

Description

technical field [0001] The invention belongs to the technical field of railway traffic management, in particular to a blocking system and method. Background technique [0002] As a high-quality renewable resource, train braking force has never been deeply explored to ensure the service security of train operation control and improve the resource management efficiency of railway traffic management. resource management), the new generation of information system (information system) needs to deploy a technical solution of resource information mining (resource information mining). [0003] Blocking (block system) means that the railway sets up a set of traffic equipment and traffic organization system in traffic management to control the movement of the train section. Contact system after failure due to failure), to ensure that at the same time, there is only one train running between stations, between stations, and in the block area, with automatic block, semi-automatic block,...

AI Technical Summary

Problems solved by technology

The three-display automatic block and the four-display automatic block have the problems of limited passing capacity and difficult production and maintenance. The CTCS-3 train operation control system has problems such as long transmission path of train radio communication waves, insufficient timeliness and security of wireless network space. CTCS-3 also has the problem of poor terrain adaptability and / or poor maintainability of the train radio communication system in the geographical environment of mountains, canyons, long tunnels, no-man's land and land bridges, and the CBTC system has the problem of excessive train tracking intervals. As a result, it cannot meet the transportation capacity demand of the subway system in the morning and evening peak hours. The new generation of information system needs to deploy a new technical solution.
