摘要:
目的：采用现有的列车动态测试方法时，双列位停车库的两个停车位中间须设置动态测试缓冲区段，费用高且占用很多资源。对此，提出基于虚拟分区的城市轨道交通全自动运行控制系统动态测试的安全防护方法。方法：在现有的安全防护流程和方法的基础上，结合限速曲线防护措施，通过虚拟分区的方式，在休眠唤醒区域划分唤醒测试防护区和动态测试管理区，进而对动态测试的授权及过程进行安全防护。从动态测试管理区之间有无交集的情况出发，着重针对动态测试管理区包含其他防护对象的特殊情况，阐述了列车动态测试授权的安全防护过程。分析了动态测试过程中的安全防护内容及过程。定义唤醒测试防护区用于防止进行动态测试的列车跳出预设的测试位置，由车载控制器控制列车不超出动态测试范围。配置动态测试管理区用于防止冲突进路和其他列车的移动授权进入测试列车的防护范围，区域控制器控制其他列车的移动授权到达动态测试管理区边界之外。结果及结论：采用虚拟分区进行安全防护的设计方法，在双列位停车库的两个停车位之间无需设置缓冲区段，可缩短测试列车与相邻区段停靠列车之间的距离，提高运营效率，同时节约了土建和信号设备成本。
Abstracts:
Objective: When using existing train dynamic testing method, it is necessary to allocate a dynamic testing buffer zone between every two parking lots in a doubletrack parking garage, which incurs high costs and consumes significant resources. To address this issue, a safety protection method for dynamic testing of urban rail transit FAO (fully automatic operation) control system based on virtual partitioning is proposed. Method: Building upon existing safety protection procedures and methods, combined with speed limit curve protection measures, this method employs virtual partitioning to divide the sleepwake area into WTP (wakeup testing protection zone) and DTM (dynamic testing management zone), thus ensuring the safety protection of dynamic testing authorization and process. Based on the scenarios of intersecting or nonintersecting DTM, special cases involving the inclusion of other protection objects in DTM are specifically addressed to explain the safety protection process for train dynamic testing authorization. The safety protection content and process during dynamic testing are analyzed. The WTP is defined to prevent the test train from deviating from the designated testing position, with the onboard controller ensuring that the train remains within the dynamic testing range. DTM is configured to prevent conflicting routes and other trains from entering the protection range of the test train, with the zone controller authorizing the movement of other trains up to DTM boundary. Result & Conclusion: The design approach using virtual partitioning for safety protection eliminates the need for a buffer zone between every two parking lots in a doubletrack parking garage. This shortens the distance between the test train and the adjacent section of parked trains, improving operational efficiency while saving costs associated with civil engineering and signaling equipment.
