Maritime safety navigation intelligent induction device

Abstract

The invention discloses a maritime safety navigation intelligent induction device. The device can automatically calculate and generate an optimal safe navigation route based on the position of an induced ship OS at an arbitrary time and display the route on ECDIS from the position to the plan end point of the voyage. When a passing ship is in a monitoring distance around the induced ship, the device can automatically judge the risk and generate a cautious angle. Different colors are used to indicate the cautious angle of the induced ship OS relative to different passing ships TS, and the sidelength of the cautious angle can be further used to distinguish the cautious angle of the OS relative to different TSs and indicate the minimum speed of the OS with collision, so as to indicate the order in which the induced ship OS contacts or collides with different passing ships TS and the maximum speed of the OS to avoid collision. The range of safe heading angles for the induced ship OS, a careful navigation angle range relative to different TSs, and the extent to which the OS needs to be slowed down during voyages in the careful navigation angle range to ensure safety are acquired. An intelligent safe navigation support is provided for a driver.

Description

technical field [0001] The invention relates to the field of ship route planning and design, in particular to an intelligent induction device for safe navigation at sea. Background technique [0002] When designing ocean and inland ship routes, the professional knowledge and experience of pilots are now mainly used to manually design ship routes between origin and destination ports. Although with the help of computer-aided software, it is sometimes possible to generate a route by manually selecting waypoints on the electronic chart system (ECDIS), it is still inseparable from manual intervention in order to improve and optimize the route based on this There is a big gap between automatic route generation and optimization. When the ship passes through waters where there are many navigable areas or the navigation waters are restricted, such as passing through water construction areas, the workload of manual intervention is even greater. Not only that, when a ship sails along...

AI Technical Summary

Problems solved by technology

[0004] However, the deficiencies of the existing technology include: first, it is not possible to automatically generate safe and efficient routes under the general conditions of a given port of departure, especially when the navigation of the ship passes through waters is restricted; second, in busy waterways, ports or construction In the area, there may be many ships passing by, which will cause great interference to ships sailing according to the planned route. In an emergency situation, it is impossible to quickly and accurately point out the correct route selection or avoidance decision. It also needs to be calculated manually or based on experience based on radar and AIS information. It is judged that the existing technology is difficult to provide intelligent and safe navigation support for the driver; third, the accuracy of the existing radar alarm device is low

For example, although the ARPA radar has the functions of setting the alarm range, forecasting the minimum distance of encounter with other ships (DCPA) and the time to the closest encounter point (TCPA), it often cannot accurately predict the degree of risk

Especially when there are dense ships nearby or on the route (such as the Yangtze River Estuary Channel), excessive alarms will seriously affect the driver's mood and thoughts
