The invention discloses a fishing boat anti-collision early warning method and system based on a system safety theory, and the method comprises the steps: obtaining the navigation monitoring information of a fishing boat, detecting other navigation ships in a current region according to the navigation monitoring information of the fishing boat, and carrying out the situation analysis, and obtaining the situation analysis information; acquiring a ship collision risk assessment instance based on data retrieval to perform ship collision risk assessment element selection, setting a collision risk assessment index and constructing a collision risk assessment model; performing collision risk assessment according to the situation analysis information to obtain collision risk assessment information, performing anti-collision early warning prompt, constructing a collision avoidance responsibility judgment rule, and performing collision avoidance responsibility judgment in combination with the collision risk assessment information; collision avoidance priority judgment is carried out according to the collision risk assessment information, a collision avoidance route making model is constructed based on an SAGA algorithm to make a collision avoidance route, and collision avoidance responsibility judgment and collision avoidance intention analysis are carried out on a next collision avoidance ship. And the anti-collision effectiveness and reliability of the fishing boat are improved.

    本发明公开了一种基于系统安全理论的渔船防碰撞预警方法及系统,包括:获取渔船航行监测信息,根据所述渔船航行监测信息检测当前区域的其他航行船只,并进行态势分析,得到态势分析信息;基于数据检索获取船舶碰撞危险评估实例进行船舶碰撞危险评估要素选取,设定碰撞危险评估指标并构建碰撞危险评估模型;根据态势分析信息进行碰撞危险评估获取碰撞危险评估信息,并进行防碰撞预警提示,构建避碰责任判定规则,结合所述碰撞危险评估信息进行避碰责任判定;根据碰撞危险评估信息进行避碰优先级判断,基于SAGA算法构建避碰路线制定模型进行避碰路线制定,并对下一避让碰撞船只进行避碰责任判定和避碰意愿分析。提高渔船防碰撞的有效性和可靠性。
