摘　　要：三维视景技术已广泛应用于城市轨道交通领域,取得了不同程度的成果,但大多局限于列车驾驶培训和教学三维演示。提出基于微软模拟火车(MSTS)的三维视景与车载列车自动防护(ATP)系统结合的仿真研究。以郑州地铁1号线为线路原型,简要介绍视景系统的建立过程;利用开源平台的开源铁路(OR)提供接口,设计了仿真系统的结构和功能;根据超速防护模型及计算算法,并以三维视景中的实际线路为例,实现了列车的测速定位、超速防护、速度监督等关键车载ATP功能。经测试验证,达到预期仿真目的和效果,为城市轨道交通控制系统的仿真研究和测试提供了新思路。Three-dimensional vision technology has been widely used in the field of urban rail transit,and has achieved various results,but mostly limited to train driving training and teaching threedimensional demonstration.A simulation study based on Microsoft Train Simulation(MSTS)and on-board Automatic Train Protection(ATP)is proposed.Taking Zhengzhou Metro Line 1 as the real-time scenario,this paper briefly introduces the establishment process of the visual system,designs the structure and function of the simulation system by using the Open Railway(OR)interface of the open source platform.According to the overspeed protection model and calculation algorithm and by taking the actual line in the three-dimensional vision as an example,the train speed measurement and positioning,speed protection speed monitoring and other key on-board ATP functions are realized.Through test and verifi cation,the expected simulation purpose and effect are achieved,which provides a new idea for simulation research and test of urban rail transit control system.
