摘要
为解决列车经过交叉渡线形成X型交汇点时,既有MTC-Ⅰ型CBTC信号系统无法按计划运行图控制列车路权顺序的问题,提出一种基于虚拟交汇点的管理方法。首先,通过构建虚拟交汇点,为X型交汇点计算虚拟等效计划列表;其次,将虚拟等效计划列表应用到对应的自动进路冲突检测中,检测结果可作为控制列车路权顺序的依据。最后,测试该方法可有效控制列车经过X型交汇点的路权顺序,提高列车计划运行图与实际运行图的重合率,进一步降低因X型交汇点导致的列车晚点、区间停车风险。
To solve the problem of the existing MTC-ⅠCBTC signal system not being able to control the train right-of-way sequence according to the planned operating diagram when trains pass through the X-shaped junction formed by intersecting crossover,a management method based on virtual junctions is proposed.Firstly,by constructing a virtual junction,an equivalent plan list for the X-shaped junction is calculated.Secondly,the virtual equivalent plan list is applied to the corresponding automatic route conflict detection,and the detection results can serve as the basis for controlling the sequence of train right-of-way.Finally,this method can effectively control the rightof-way sequence of trains passing through the X-shaped junction,improve the overlap rate between the planned train diagram and the actual train diagram,and further reduce the risk of train delay and interval parking caused by the X-shaped junction.
