The invention discloses a port water area ship traffic risk early warning method. The method comprises the following steps: S1, starting a system, and detecting a working state of port water area shiptraffic risk early warning in real time; S2, judging a port water area ship traffic risk early warning working state; S3, carrying out risk cause analysis information and risk early warning mechanisminformation; S4, performing information fusion processing on the acquired risk cause analysis information and risk early warning mechanism information; S5, according to a ship collision risk measurement model, combining the risk cause analysis information and the risk early warning mechanism information; S6, constructing an early warning index system; S7, generating a rough set reduction index according to different risk values; S8, constructing an SVM training model by using a modeling software SVM algorithm; S9, carrying out precision inspection; and S10, giving an early warning result.

    本发明公开了一种港口水域船舶交通风险预警方法,包括如下步骤:步骤S1、启动系统,实时检测港口水域船舶交通风险预警的工作状态;步骤S2、判断港口水域船舶交通风险预警工作状态;步骤S3、风险成因分析信息和风险预警机制信息;步骤S4、将采集到的风险成因分析信息和风险预警机制信息进行信息融合处理;步骤S5、根据船舶碰撞风险测度模型,结合经风险成因分析信息和风险预警机制信息;步骤S6、构建预警指标体系;步骤S7、根据不同的风险值,生成粗糙集约简指标;步骤S8、用建模软件SVM算法构建SVM训练模型;步骤S9、精度检验;步骤S10、预警结果。
