摘　　要：以轨道交通驾驶训练为背景,介绍了模拟训练的设计方案。利用模块化设计实现计算机与操作单元的分布式仿真:PLC模块实现操作单元的指令和数据传输,通过RS485/232实现控制台计算机对操作单元检测与控制;采用四通道视景系统作为输出界面,Creator构建轨道站点和沿线环境模型,Vega实现模型驱动。应用表明该系统在实时性、逼真度和开放性等方面比视频模拟器均有较大提高,并已成功应用于某城市轨道交通视景仿真模拟器中。Introduce the design scheme of simulation training based on driving of urban mass transit.Distributed simulation among computers and operation units has been realized according to module design;PLC module is applied to realize the transmission of instruction and data,computer detects and controls operation panel through RS485/232;four channel visual system is taken as output interface;platform and environment models are constructed in Creator,models are driven in Vega;the application shows that the system has far more real-time,fidelity and open than video simulator and has been applied successfully in urban mass transit simulator.
