油田事故应急救援可视化决策支持系统

针对现行油田事故应急救援机制的不足，基于WebGIS技术构建一个油田事故应急救援可视化决策支持系统，通过网络实现各级应急救援指挥机构异地统一指挥、协同救援，提供全方位、可视化、高效的应急救援信息服务与决策支持，以提高应急救援的科学性和时效性。给出系统的体系结构与功能设计及关键技术实现，包括客户端与服务器的通信、地图的加载与显示、救援最优路径算法模型。

Visualization Decision-making Support System for Oilfield Accident Emergency Rescue

Aiming at the lack of current emergency rescue mechanisms for oilfield accidents, this paper proposes a visualization decision-making support system for oilfield accident emergency rescue based on WebGIS. It combines all levels of emergency rescue command organizations in different locations by network, thereby cooperating to emergency rescue. And it provides all-side, visualization and high-efficiency information services, along with decision-making support so as to improve emergency rescue in terms of scientific and real-time characters. Its architecture and key techniques of the system are presented, including asynchronous communication between the client and the server, load and display of map, and model of optimal rescue path algorithm.
