CTCS-2级列控系统大号码道岔有源应答器组特殊场景探讨

Discussion on Special Scenarios of Switchable Balise Group for Large Number Turnouts in CTCS-2 Level Train Control System

描述高速铁路大号码道岔应答器组的设置和报文发送方式,并对报文数据差异、接近区段长度距离不足和短区间等特殊场景下造成列车在通过大号码道岔时降速运行原因进行分析,提出在工程设计、数据编制中相应的解决对策,对提高高速铁路运营效率具有一定的指导意义。

This paper fi rstly describes the setting of switchable balise group for large size turnouts and the method of sending telegrams in the high-speed railways.Then an analysis is conducted on the reasons for train speed reduction when passing through large turnouts in special scenarios such as inconsistent telegram data,insuffi cient distance of approaching sections and short sections.Finally,it summarizes several types of problems frequently encountered in engineering design and data compilation,and proposes the corresponding solutions,which have certain guiding signifi cance for improving the operational effi ciency of high-speed railways.
