【摘要】 摘要：磁浮列车是一种运行时速为400-500km/h的高效运输陆地交通工具。列车高速运行中需要采用性能优越,安全可靠的列车运行控制系统来保证列车的安全、高效运行。分区切换是高速磁悬浮列车运行控制系统的重要功能之一。高速磁浮分区切换的效率直接影响列车运行效率和安全。目前,关于高速磁浮分区换的研究较少,因此建立高速磁浮分区切换的CPN模型并分析影响切换效率的关键因素至为重要。论文首先分析了和分区切换有关的高速磁浮列车控制系统的组成结构和工作原理,其中包括分区运行控制系统、车载运行控制系统。然后分析了磁浮分区切换的流程以及功能模块,主要包括分区切换的DSC功能模块、安全速度防护计算模块、停车点步进等。然后介绍了petri网原理, CPN建模方法和CPN建模在轨道交通列车控制系统中得应用。在这些基础上,采用自顶向下的建模方法建立了高速磁浮分区切换的CPN顶层模型、38GHZ无线信道CPN模型、相邻磁浮分区通信CPN模型、生成最大速度曲线的CPN模型、车载运控系统和分区运控系统建立通信的CPN模型、停车点步进模型等。最后分析了高速磁浮分区切换的CPN模型验证方法,对建立的分区切换模型进行状态空间分析验证,并分析了影响分区切换效率的关键因素。重点仿真分析了38GHZ无线通信系统、DSC交换报文效率、列车速度对分区切换效率的影响,并得出了在不同列车速度下的高速磁浮分区切换的用时分布,为磁浮列车控制系统的工程应用提供一定的参考。更多还原

【Abstract】 ABSTRACT:The Maglev is an efficient land transport vehicle which running at a speed up to400-500km/h. Safe and reliable train operation control system should be adopt to ensure train safety, efficient operation. The switch function of high speed Maglev is an critical function of Maglev train operation control system and the efficiency of high speed Maglev’s operation and safety has largely depends on the efficiency of switch. As there’s hardly any research about the Maglev’s switch function, so it’s important to model the switch function of Maglev and analyze the key factors which determine the efficiency of it.Firstly, the structure and operation principle of high speed Maglev’s train operation control system which mainly includes the discrete operation control system, vehicle on board operation control system was introduced. Then, the process and function of Maglev’s switch was designed, of which include the DSC function module, safety velocity compute module,stop point step in module etc, Also, the principle of petri net and the CPN model method and the using of CPN in the rail transportation control system area were introduced.In the base of above research, the CPN model of high speed Maglev’s switch function’s,38GHZ’s radio communication channel, Max velocity curve, the session between train and DCS, step in function were modeled. Finally, the verification method of high speed Maglev switch function’s CPN model of was introduced, then the key factors which determine the efficiency of maglev’s switch function were researched, include the failure of38GHZ radio communication channel, DSC transfer efficiency, and train speed.Also, the distribution of high speed Maglev’s switch timed consuming was researched.更多还原
