specific Embodiment

[0030] See attached Figure 1 Embodiments of the present invention, for example, as follows: a high-speed railway crossing control system, comprising: a host unit, a communication extension unit, a monitoring unit, a digital IO unit, a railing machine driver unit, a crossing signal machine driver unit, a communication protocol conversion unit, a relay group, and a local control panel.

[0031] The high-speed railway crossing control system is based on a safety computer platform that has passed safety certification, which is a 2×2 system and a single system of 2 to 2 for safety. The two series are redundant with each other, and when either series fails, it will not affect the normal operation of the other series. On the safety platform, the application logic of the crossing control system is implemented. The intersection control system controls peripheral equipment according to logic, including crossing signal machines, railing signal machines, main body signal machines, outdoor aud...

Abstract

The invention relates to a high-speed railway crossing control system. The high-speed railway crossing control system comprises a host unit, a communication expansion unit, a monitoring unit, a digital IO unit, a barrier machine driving unit, a crossing signal machine driving unit, a communication protocol conversion unit, a relay group and an in-situ control panel. The ETCS-2-level line level crossing control system architecture suitable for European railways is realized, and the level crossing control system is based on an SIL4-level ART safety computer platform and is combined with LEU and computer interlocking.

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...
