应急响应过程事故模拟可视化的实现

Realization of Accident Simulation Visualization in the Process of Emergency Response

介绍了应急响应过程中事故模拟可视化展示的基本参数选取、数据流向及实现流程。针对泄漏、火灾、爆炸事故,根据事发现场气象条件、泄漏源参数及事故物质的物化特性,调用相应的事故计算模型对事故进行模拟计算,并对计算数据进行可视化展示。如果突发事故为火灾,系统可以根据消防车消防能力、消防管网信息智能地计算,展示消防车的占位情况,并自动为占位消防车分配任务。

This article describes the selection of basic parameters, data flow and realization process of acci- dent accumulation visualization in the process of e- mergency response. The accident is simulated calcu- lating by invoking corresponding accident calculating model based on the onsite weather condition, leakage parameters and the physicoehemical properties of ac- cident substances for leakage, fire and explosion ac- cident, and then the result data is rendered. If the accident is fire, the system could calculate and show the deployment of fire engines according to the fire engines＇ capacity and fire pipe network information.
