全自动运行系统下站台门新增异物探测与控制功能方案研究

Scheme Research on Added Foreign Objection Detection and Control Function to Platform Screen Door under Fully Automatic Operating System

全自动运行(FAO)系统是城市轨道交通自动化的最高等级,站台门是全自动运行系统中与乘客直接接触的保障系统安全运行的重要设备,目前全自动运行系统下站台门新增功能需求与实施方案尚无规范标准可循。通过对全自动运行系统下站台门运营场景需求分析,得出站台门在全自动运行系统下间隙异物探测、车辆与站台门故障对位隔离和多就地控制盘(PSL)控制功能需求;针对传统的车辆与站台门间隙异物探测方案进行全自动运行系统适用性分析与比选,提出全自动运行系统站台门间隙异物探测技术要求及发展方向;对实现列车门与滑动门故障对位隔离控制功能的信息传输通道和控制模式进行研究分析,并对此运营场景的客流引导播报方案提出新的思路。同时,确定了全自动运行系统下站台门PSL位置和数量的设置原则。

Fully automatic operating(FAO) system is the highest level of urban rail transit automation and the platform screen door is the important equipment in direct contact with passengers to guarantee safe system operation. Currently, there have been no specifications for the newly added function requirements and executive schemes of the platform screen door. This article analyzes the platform screen door operating requirements under the FAO system, and defines the control requirements for the detection of foreign objects in the platform screen door’s gap, failure contraposition and isolation between vehicle and platform screen door, and multiple platform screen door local control panel(PSL). Based on FAO system applicability analyses, comparison and selection of foreign objects detection schemes related to traditional vehicle and platform screen door, technical requirements and development direction of the detection system are addressed. Researches are conducted on information transmit passageway and control mode to fulfill the contraposition and isolation of the failure between vehicle door and sliding door, and new thinking of passenger flow guiding broadcast scheme under this operating mode is proposed. Meanwhile, principles for setting PSL position and quantity under FAO system are determined.
