摘要:
［目的］在全自动运行地铁线路中，站台门与列车之间存在间隙，有夹人夹物的风险。为确保行车安全，必须设置间隙探测装置。［方法］简要叙述了间隙探测装置的现状，重点讨论了激光间隙探测装置的工作状态，对比了激光间隙探测装置与列车运行进行互锁以接入行车安全回路的两种模式，并对全自动运行地铁线路中防夹安全装置的应用提出建议。［结果及结论］激光间隙探测装置的启动和停止由信号系统直接控制，并由信号系统直接获取该探测装置的间隙检测状态。激光间隙探测装置是在列车门和站台门均关闭且锁紧后才开始检测，避免了在站台门关闭后而列车门仍未关闭这种极端情况下的检测，对于探测装置而言其探测环境更优。当装置探测到有障碍物或误报时，信号系统可自动控制车门和站台门重新开关，门关好后重新启动探测，降低对地铁运营的影响。另外，在全自动运行地铁线路中，考虑同时设置传统物理防夹装置及激光间隙探测装置，预防发生站台门夹人事故。
Abstracts:
［Objective］ On the fully automatic operation metro lines, there exists a gap between the platform screen door and the train, leading to the risk of clamping people and objects. In order to ensure train operation safety, a gap detection device must be installed. ［Method］ The current situation of the gap detection device application is briefly described, the working state of the laser gap detection device is mainly discussed, two interlocking modes of the laser gap detection device and the train operation are compared in order to access the safety loop of the train, and put forward some suggestions on the application of the anti-clamping safety device on the fully automatic operation metro lines. ［Result & Conclusion］ The signal system directly controls the start and shutdown of the gap detection device, and obtains the gap detecting state of the device. The laser gap detection device starts to work only after both the train door and the platform screen door are closed and locked, avoiding the extreme situation in which the platform screen door is closed but the train door still open. This mode provides a more favorable working environment for the gap detection device. When the device detects an obstacle or a false alarm, the signal system can automatically control the train door and the platform screen door to reopen and close, and restart the detection after the doors close, reducing impact on the metro operation. In addition, in fully automatic operation metro system, both the traditional clamping-proof device and the laser gap detection device are considered to be installed to prevent people from being clamped by the platform screen doors.
