摘　　要：列车运行控制系统仿真是研究列控系统的一个十分有效的手段。采用多分辨率建模理论,能够准确建立列控系统仿真模型,而多分辨率模型描述是多分辨率建模理论研究的基础环节。针对列控系统结构明确、仿真分布式的特点,提出了一种新的多分辨率模型描述方法,该方法将多分辨率建模与多分辨率仿真进行区分,提出了多分辨率模型域的概念,从而在仿真过程中,不同分辨率模型结构可以实现动态切换且不影响仿真系统的正常运行,为了维护模型间以及模型与仿真系统的一致性,设计了接口模型,以此解决了模型分辨率切换的数据正确性问题。对列控系统运行的简单过程进行了建模,通过仿真可以看出该方法的优势所在。Simulation of Research of train operation control systems is an efficient way to study train operation control systems.By the multi-resolution modeling theory,the accurant train operation control simulation mod-el can be constructed train operation control systems.Description of the multi-resolution model is the groundw-ork in study of the multi-resolution modeling theory.In this paper,in the light of the features of clear structure and distributed simulateion of train operation control systems,a new multi-resolution model description meth-od was proposed.With this method,multi-resolution modeling was separated from multi-resolution simulation while the concept of multi-resolution modeling space was put forward so that model structures in different reso-lutions could be converted dynamically during simulation without disturbing the operation of the simulation systems.The interface model was designed to maintain consistency between model and between models and simulation systems and to keep correctness of models data in model resolution switching.A simplified procees of train operation control was modeled and through simulation the advantages of the proposed method were demonstrated.
