汽车环境污染预警机制研究*

对汽车环境污染预警机制进行了研究，通过分析汽车环境污染的种类和危害提出了建立汽车环境污染预警机制的必要性。设计了预警机制的基本结构，建立了基于预警指标体系和知识表示的预警综合数据库，并且通过划分预警指标等级、设计预警规则及其知识表示建立了预警知识库，用预警推理机来协调整个预警机制。通过研制原型系统并设计预警实验，证实了提出的汽车环境污染预警机制的正确性和可行性。

Research on early-warning mechanism for environmental pollution caused by automobile

This paper researched on early-warning mechanism for the environmental pollution caused by automobile. Through analyzing the types and hazards of the environmental pollution caused by automobile, proposed the need of establishing an early-warning mechanism. This paper designed the basic structure of early-warning mechanism, and established the early-warning comprehensive database based on early-warning indicator system and knowledge representation. And also, established the early-warning knowledge-base through dividing the level of early-warning indicators and designing the early-warning rules and their knowledge representation, and coordinated the whole early-warning mechanism by the early-warning inference engine. Furthermore, through developing a prototype system and designing an early-warning experiment, it validates the feasibility and accuracy of early-warning mechanism.
