考虑到分布式逆向WADGPS在列车调度指挥管理系统中的必要性及其优点,综合国内外已有的列车调度方式,提出基于分布式逆向WADGPS的列车调度指挥管理系统。系统采用WADGPS、里程表、车速仪、陀螺仪等构建分布式逆向WADGPS组合定位模型并对多传感器信息进行融合处理,解决列车定位的精度和盲区问题;在精确获取列车位置和速度的基础上,结合GIS和GSM-R技术和专家系统构建列车智能调度管理系统。经过模拟实验,表明该系统具有可行性。
Considering the necessity and advantages of distributed reverse WADGPS in train dispatching command and management system, this paper proposes a train dispatching command and management system based on distributed reverse WADGPS based on the existing train dispatching methods at home and abroad. The system uses WADGPS, odometer, speedometer, gyroscope and so on to construct the distributed reverse WADGPS combined positioning model and to fuse the multi-sensor information to solve the problem of locating accuracy and blind spot of the train. On the basis of accurately obtaining the train position and speed, Construct Train Intelligent Dispatch Management System Based on GIS and GSM-R Technology and Expert System. After simulation, it shows that the system is feasible.
