AI Technical Summary

Benefits of technology

This patented technology describes an improved way for controllers called Shipple Event Trigger (SGT) that detects when there're no ship on their route or approaching them accurately without having multiple drones involved. It uses delayed observed events from different sources like radar systems or cameras instead of sending all data every second over long distances. By doing this, it reduces computational load while still maintain high accuracy. Overall, these improvements make SGT more efficient than current methods by allowing faster detection times and less complex algorithms.

Problems solved by technology

This patented technical problem addressed in this patents relates to managing large numbers of autonomous boats without sacrificial resources due to potential threats from foreign objects like fisheries. Current systems only allow one boat to cover different areas but lack coordination capabilities. There needs improvement over these techniques to improve efficient navigation and mission management within harsh environments where numerous dronysons exist simultaneously.

Abstract

The invention discloses an unmanned ship event triggering hierarchical cooperative control system, which comprises a distributed event triggering state observation module, a position tracking control module, a communication network, an unmanned ship and a target ship. The distributed event triggering state observation module is used for monitoring an adjacent unmanned ship in real time, and when the position information of the neighbor ship is updated, triggering the unmanned ship to observe the position and speed information of the target ship, and comprises a first event triggering unit and a distributed observation unit, and the position tracking control module is used for estimating the position, angle and speed tracking error of the target ship and triggering the unmanned ship to track the target ship. The the position tracking control module comprises a tracking control unit, a third event triggering unit and a reduced-order distributed observation unit, the distributed observation unit and the tracking control unit are designed in a layered mode, independence of all layers is achieved, through cooperation of all the layers, the complexity of the multi-unmanned-ship target tracking problem is effectively reduced, and the expansibility of the multi-unmanned-ship target tracking control system is improved.
