新型列控系统和ETCS-2级列控系统目视授权差异性研究OA

The on-sight authorization function is a core function in the new train control system and the ETCS-2 train control system.This paper takes the on-sight authorization function as the starting point,and expounds on the background and significance of this research.It also systematically elaborates on the application of the on-sight authorization function in the two systems from the aspects of key information interaction and core processes.Additionally,it sorts out the differences of the on-sight authorization function in the two systems from four aspects,i.e.,information interaction,authorization process and security mechanism,supervision distance,and operation scenarios.This paper provides reference ideas for the"on-demand design"of train control systems and the multi-scenario adaptation for the overseas application of China's high-speed railway technologies through the analysis of differences.At the same time,it provides an integration scheme of"precise track positioning"and"multi-scenario adaptation"for the introduction of the on-sight authorization function into the CTCS-3 train control system.
