Description

Technical field

[0001] The present invention relates to the field of high-speed railway technology, in particular to a high-speed railway crossing control system. Background

[0002] Railway level crossing refers to the place where railways and highways intersect with each other on the same plane, which is an important and special part of railway transportation, and is the only area in the entire transportation network where there is a conflict between road and railway right of way. Level crossings are a section that cannot be ignored in the entire railway network, but level crossings are accident-prone areas, and once an accident occurs, it directly threatens people's lives. Therefore, in order to prevent collisions between trains and motor vehicles or pedestrians, reasonable arrangements for the alternating opening of railway right-of-way and highway right-of-way, level crossings need to be equipped with corresponding control systems.

[0003] At present, in addition to the...
