Abstract

The invention relates to an autonomous navigation control management system for a large unmanned ship. The autonomous navigation control management system comprises a whole ship information subsystem,an autonomous navigation control subsystem, an operation motion simulation subsystem, an autonomous dynamic collision avoidance decision planning subsystem, a ship-shore interaction visual display subsystem, a signal acquisition subsystem and a propulsion controller, wherein the signal acquisition subsystem acquires the ship and marine environment information and transmits the ship and marine environment information to the whole ship information subsystem for information fusion, the whole ship information subsystem transmits the fused information to the manipulation motion simulation subsystem, the autonomous dynamic collision avoidance decision planning subsystem and the ship-shore interaction visual display subsystem for calculation, and the ship-shore interaction visual display subsystem receives active planning and control of the shore base through network communication. The autonomous navigation control management system of the large unmanned ship realizes autonomous collision avoidance decision and real-time simulation verification in the control process, and perfects shore-based joint control and real-time monitoring.

Description

technical field [0001] The invention relates to the technical field of unmanned ship control, in particular to a large-scale unmanned ship autonomous navigation control management system. Background technique [0002] The main causes of ship accidents at sea come from improper judgment of the ship itself and environmental factors by the crew on board and mistakes in human decision-making and control. In addition, the personnel costs of ship sea operations are high, the demand for senior crew is large, and the living and working space of the crew accounts for a large proportion of the ship space. Reduced sea transportation efficiency. Unmanned ship navigation technology can effectively solve the above problems, and the navigation control management system with autonomous navigation and independent decision-making is a key link in unmanned ship control technology. Chinese patent CN108489492A discloses a path planning system for unmanned boats considering sea conditions. The p...
