两线同站分场共用股道跨线方式信号方案研究

Research on the Signal Technology Scheme of the Train Running Mode between the Two Different Standard Lines

研究目的:两条干线铁路间跨线运行通常是采用联络线方式实现的,但合福客运专线与九景衢铁路间的跨线运行是通过在婺源站两线同站分场、共用股道来实现的,因此需要针对此种特殊的站场布局研究满足运营需求的信号设计方案。研究结论:(1)婺源站两场各自单独联锁,交叉渡线道岔控制纳入Ⅰ场联锁,跨线进路均分段办理;(2)信号机显示按照Ⅱ场跨线至Ⅰ场接发车点灯、Ⅰ场跨线至Ⅱ场接发车不点灯;(3)九景衢线的动车跨线至合福客专线不设C3等级转换点,利用Ⅰ场各发车口的自动转换方式;Ⅰ场跨线接车至6G,6G设ZX-3/2转换点;Ⅰ场5G跨线发车采用扩大GSM-R覆盖范围,在九江方向的区间设置ZX-3/2转换点实现;(4)临时限速采用两场的TSRS通过安全数据网通信实现;(5)此信号方案可供类似工程参考借鉴。

Research purposes： Generally the mode that the train runs across two main lines is realized by the junction lines, but the running way between the Hefei - Fuzhou Passenger Dedicated Line and the Jiujiang - Jingdezben - Quzhou Mixed Traffic Line is realized by two yards and one shared track in the Wuyuan station. So the signal design needs to make a scheme to meet the transportation needs of the junction station special layout. Research conclusions： （1）Wuyuan station designs two respective interlocking systems for the two yards, and the intersecting cross - over turnout is controlled by the interlocking system of the yard I. The route between two yards is set up by some sectional routes. （2）The signal indication turns on when the train runs from the yard II to the yard I, while the signal indication turns off when the train runs from the yard I to the yard 1]. （3） Due to the automatic transition mode of every home signal, the CTCS -3/2 grade transition point does not need to be set up, when the EMU runs from the Jiujiang - Jingdezhen - Quzhou Railway to the Hefei - Fuzhou Passenger Dedicated Line. The execution point of ZX -3/2 needs to be set up on the 6G track, when the train runs from the yard I to the 6G track. The train control grade transition from CTCS - 3 to CTCS - 2 is realized by expanding the GSM - R coverage scope and setting up the action point of ZX - 3/2 on section of Jiujiang direction, When the train departure from the 5G track of the yard I. （4） The temporary speed restriction is achieved by the temporary speed restriction server （TSRS） and the secure data network. （5）This signal scheme is a reference for some similar projects.
