点式应答器在提高大连快轨3号线大连站折返能力中的应用

摘要

随着大连社会经济的迅速发展,大连快轨3号线既有线路的运能和需求之间的矛盾日益突出.快轨3号线大连站折返能力成为阻碍减小发车间隔、提高线路运能的制约因素.介绍了通过增设点式应答器提高快轨大连站折返能力的应用过程.通过对改造后的大连站折返能力的实测结果表明,采用地面应答器和车载查询器相配合,在不改变原有信号制式及模式下可成功地提高车站的折返能力.%With the rapid development of social economy in Dalian City, the contradiction between the transport capacity on existing lines and the needs of Dalian Rapid Rail Line 3 becomes increasingly prominent. The turn-back ability of Dalian Rapid Rail stations is the main constraining factor in compressing departing intervals and improving the line capacity. In this paper, the combination of ground and on-board spot responders for the improvement of turn-back ability and the actual measurement after the reform project at Dalian Rapid Rail stations are introduced.
