基于GIS的铁路行车事故救援系统研究

Study on Emergency Rescue System for Accidents of Running Train Based on GIS

笔者扼要探讨了构建基于GIS的铁路行车事故救援系统的相关理论和方法 ,提出了该系统的设计目标、功能结构、体系结构以及空间数据库设计的简要准则和空间数据的输入方法。笔者还介绍了结合实际科研项目 ,开发的大秦线事故救援辅助决策支持系统。该系统具有以下几方面的特点 :在以工务信息为主体的基础上 ,实现了车、机、工、电、辆各部门主要业务信息以及事故救援预案信息的初步整合 ;实现了线路录像按里程点播以及录像与线路设备综合图的联动 ;实现了事故救援的辅助决策支持 ,提供了一个可以扩展的理想平台。

The pertinent theories and methods of the emergency rescue system for accidents of running train based on GIS are discussed. The design goal, functional structure, system structure, simple guidelines for designing spatial databases and the input method of the spatial data are put forward. Combing with the scientific research projects, the supplementary decision support rescue system for accidents of running train on Datong-Qinhuangdao railway is developed. This system has following characteristics: the integration of the main business information about the railway departments of transport, locomotive, engineering, vehicles and multimedia information with prediction scheme information about accidents happened, and establishment of a subsystem of querying the multimedia information of the relevant railway district and realization of the linkage between line equipment comprehensive maps and videos, which provide the supplementary decision support for the rescue of accidents of running train and an ideal and easy-to-expand platform.
