高速铁路行车指挥过程是一个多层次、涉及多系统的信息交互过程,目前的研究多侧重于局部系统的研究,对高铁行车指挥的全局控制具有一定的局限性。以信息交互过程为切入点对涉及该过程的行调子系统、列控子系统、计算机联锁子系统进行统一建模,并提出全局模型在建模及应用两方面的拓展方向,为高速铁路行车指挥过程的后续研究提供新的思路。论文基于面向对象的Petri网(Object-Orient Petri net,OOPN)建模方法建立高速铁路行车指挥信息交互过程模型并作出形式化定义。
The high speed railway traffic command process is a multilevel, multi-system information exchange process. At present, the research focuses on the research of local systems and has some limitations on the global control of high-speed rail traffic command. Taking the process of information interaction as the breakthrough point, this paper makes a unified modeling of the line transfer subsystem, the column control subsystem and the computer interlocking subsystem involved in this process. It also proposes the expansion direction of the global model in terms of both modeling and application, Follow-up research on command process provides new ideas. Based on the object-oriented Petri net (OOPN) modeling method, this paper establishes the model of interactive process of high speed railway traffic command information and formally defines it.
