摘要
为保证作业人员能够在全自动运行区域安全作业,针对地铁全自动运行系统的特点及需求,以宁波地铁5号线为例,提出了合理的人员防护开关整体设计方案。所提方案采取了出入段线、折返区域划分单独防护分区,正线按照上下行方向分别防护,人员防护开关控制电路采用双接点采集、双线圈驱动及旁路按钮双确认操作等优化措施,研究分析了人员防护开关电路设计的安全性和可靠性。研究结果表明:所提方案能够较好地适应出入段线等复杂运营场景,提高折返作业的灵活性,且符合信号系统的“故障-安全”原则。
In order to ensure that operators can work safely in the FAO(fully automatic operation)area,considering the characteristics and requirements of metro FAO system,Ningbo Metro Line 5 is taken as example,a reasonable overall design scheme of SPKS(staff protection key switch)is proposed.The proposed scheme adopts optimization measures including dividing individual protection zones for entry/exit section lines and turn-back areas,protecting the main line according to up and down directions respectively,adopting double connection point collection,double coil drive and double confirmation of bypass button of SPKS control circuit.The safety and reliability of SPKS circuit design are studied and analyzed.Research results show that the proposed operation scheme can adapt well to complex operation scenarios such as entry/exit lines,improve the flexibility of turn-back operation,and is in accordance with the′fault-safety′principle of signaling system.
