Abstract: According to the characteristics of emergency treatment and disposal for different types of sudden air pollution accidents such as diffusion leaks, fires and explosions, an emergency response system was developed for sudden air pollution accidents based on the rule engine technology. Firstly, a spatial analysis module was introduced to the rule engine to strengthen the expression and analysis abilities of environmental data. Secondly, it summarized 3 categories rules about pollution spread mode selection, classification risk areas and evacuation route optimization, and then a leakage diffusion selection rules was constructed. Finally, based on Drools rules engine technology and WebGIS spatial analysis technology, the emergency response system was implemented. An example application demonstrated that using rule engine technology can improve high efficiency, flexibility and practicality of the emergency response system.

Key words: air pollution accidents, rule engine, emergency response system

摘要： 根据泄漏扩散、火灾和爆炸等不同突发性大气污染事故类型的应急处理处置特点, 基于规则引擎技术,研发了应急处理处置系统。首先在规则引擎中引入空间算子, 增强规则引擎对空间数据的表达与分析能力。然后提出了突发性大气事故应急处理中泄漏扩散模型选择、风险区分类分级以及疏散与救援路径优化等3类规则, 并构建了泄漏扩散模型选择规则。最后基于Drools规则引擎技术和WebGIS空间分析技术实现了整个系统, 通过实例表明采用规则引擎技术提高了应急处理处置系统的高效性、灵活性和实用性。
