AIS-based water source protection method and system

The invention relates to an AIS-based water source protection method which comprises the steps: S1, dividing a water source protection region into a plurality of water source protection warning regions at different levels, and building the same number of early warning levels; S2, when a ship enters the water source protection region, acquiring the ship data of the ship through an AIS system; S3, analyzing ship behaviors according to the ship data and judging an early warning level according to the level of the water source protection warning region where the ship is located; and S4, performinghierarchical response on the ship according to the early warning level. Compared with the methods in the prior art, the method has the advantages of being good in safety, high in pertinence and the like. 本发明涉及一种基于AIS的水源地保护方法，包括：S1：将水源地保护区域划分为若干个不同等级的水源地保护警戒区，建立相同数量的预警级别；S2：当有船舶进入水源地保护区域时通过AIS系统获取该船舶的船舶数据；S3：根据船舶数据分析船舶行为以及船舶所在水源地保护警戒区的等级判断预警级别；S4：根据预警级别对该船舶进行分级响应。与现有技术相比，本发明具有安全性好和针对性强等优点。
