Abstract
The present invention discloses an intelligent navigation operation risk warning method, which includes the steps of determining a navigation safety area based on a ship area model, obtaining information of the navigation sea area and introducing it into a collision prevention assistance device, predicting an approach point coordinate according to the ship's sailing speed, the ship's course, surface obstacle information and underwater obstacle information, and re-planning the route when the approach point coordinate is within the range of the navigation safety area under the current route. By constructing a quaternion ship area model, the safe navigation boundary of the intelligent ship is determined, and various devices are used to collect surface and underwater information, predict the collision risk that may be encountered, timely plan a new route, adjust the heading and sailing speed, timely avoid the collision risk, and predict the collision risk in real time when the intelligent ship is sailing, thereby improving the safety of its sailing.
