摘要
从列车驾驶仿真器的体系结构出发,提出一种分布式列车驾驶仿真器的实现方案。该方案中,地铁列车驾驶仿真器由数据采集及输出、主控、ATC仿真、视景仿真、声音仿真、数字广播及通信仿真、运动平台控制等仿真子系统组成。子系统间采用IP组播的方式进行通信。方案支持基于DIS协议的仿真器间的通信,可实现多仿真器协同训练。为降低通信强度,提高仿真的实时性,采用一种DR算法。
Starting from the architecture of train driving simulator, a new realization solution to a distributed train driving simulator is proposed in this paper. In the solution, the simulator is composed of I/O subsystem, host computer, ATC simulator, visual subsystem, audio subsystem, digital broadcast, communication subsystem and motion base. Multicast protocol is used between subsystems of train driving simulator. The DIS protocol is supported in this architecture and multiple simulators coordinative practice can be realized. DR algorithm is used in communication to avoid network congestion problem and improve the real time of the simulation.
