The invention discloses an intelligent sailing operation risk early warning method. The method comprises the following steps: determining a sailing safety domain according to a ship domain model; acquiring navigation sea area information and importing the navigation sea area information into a radar plotter; predicting a meeting point coordinate according to the ship speed, the ship course, the water surface obstacle information and the underwater obstacle information; and if the meeting point coordinates are in the navigation safety field range under the current route, re-planning the route. By establishing a quaternary ship domain model, the safe navigation boundary of the intelligent ship is determined, water surface and underwater information is collected by means of various devices, the possible collision risk is predicted, a new route is planned in time, the course and speed are changed, the collision risk is avoided in time, and the collision risk of the intelligent ship is predicted in real time when the intelligent ship navigates. And the sailing safety is improved.

    本发明公开了一种智能航行作业风险预警方法,包括:根据船舶领域模型确定航行安全领域;获取航行海域信息并导入雷达标绘仪中;根据本船航速、本船航向、水面障碍物信息和水下障碍物信息预测会遇点坐标;若在当前航线下,会遇点坐标在航行安全领域范围内,则重新规划航线。通过建立四元船舶领域模型,确定了智能船舶的安全航行边界,借助各种设备收集水面和水下的信息,预测可能遇到的碰撞风险,及时规划出新的航线,改变航向航速,及时躲避碰撞风险,在智能船舶航行时对其碰撞风险实时预测,提高了其航行的安全性。
