摘要:
当土建原因造成线路之间的联络线长度较短时，联络线边界计轴受扰情况下，易影响正线运营。提出了一种优化设计方案：在联络线上增加1个计轴点，并划分1个无岔区段，两条线路的信号系统共享该无岔区段占用和空闲信息。该设计方法可避免侵限，也避免了出现联络线边界计轴点受扰影响正线运营的情况；可减少故障抢修时间，降低对运营的影响；可提高信号系统可用性，提高运营效率。该设计方法已应用于郑州地铁4号线的联络线设计。
Abstracts:
When the link line between lines is shorter due to civil engineering, in condition of axle counter disturbed at link line boundary, operation of the main line can be affected. An optimized design scheme is proposed: an additional axle counter point is arranged on the link line, and a section without switch is separated, the occupied and idle information of which is shared by the signaling systems of two lines. The design scheme has avoided limit invasion, as well as the situation of disturbance of axle counter point at link line boundary affecting operation of the main line. Time of fault emergency repair can be reduced, lowering influence on operation. Availability of the signaling system and operation efficiency are improved. The proposed design method has been applied to the link line of Zhengzhou Metro Line 4.
