基于区域联锁的CTC分机方案研究与建模

提出一种基于区域计算机联锁的调度集中(CTC)分机结构和方案。研究了中心站设置CTC分机和区域联锁的前提下,根据列车运行调整计划自动控制不同区域的联锁进路;将区间中继站或无道岔车站的进路控制纳入中心站,实现中心站对相邻区域进路控制范围扩展;为提高区间列车进路安全控制水平,将区域内区间信号控制纳入到联锁控制范围。最后采用UML建立了区域联锁CTC分机的用例图和序列图的模型。

Solution Research and Modelling of CTC Extension Based on Area Control Computer Interlocking

We propose the structure and scheme of a kind of CTC extension based on area control computer interlocking.With the setup of the CTC extension and area control computer interlocking at the centralized station,the system can automatically arrange the interlocking routes in different areas according to train operation adjustment plan.Meanwhile,the centralized station can expand its control over the routes of neighboring areas through bringing the control of the route at an intermediate station or a station without switch into the coverage of the centralized station.In order to improve the safety level of control over the routes within the sections,this scheme also brings the section signals within the controlling coverage into the scope of interlocking control.Finally,this paper build case diagram and sequence diagram model of the CTC extension using UML.
