Abstract

The invention discloses an unmanned vessel autonomous navigation system and a working method thereof. The system comprises an unmanned vessel autonomous navigation control unit and a ground control center, wherein the unmanned vessel autonomous navigation control unit includes a navigation system module, a guidance system module, a data acquisition system module, a propulsion system fault alarm monitoring system module, a navigation control system module and a wireless communication system module. In the invention, the influence of stormy wave flow marine environmental disturbance and obstacles in the navigation sea area on the unmanned vessel autonomous navigation system is taken into consideration, and rules in Convention on the International Regulations for Preventing Collisions at Seaand characteristic parameters and control performance of the unmanned vessel are taken into account in route planning. In addition, the system has fault alarming and fault-tolerant control functions.The system further comprises a ground control center which can remotely monitor the unmanned vessel so as to improve the rationality and practicability of the unmanned vessel autonomous navigation system. The system can monitor the unmanned vessel and marine environmental information of the navigation sea area in real time, thereby improving the safety and reliability of autonomous navigation of the unmanned vessel.

Description

technical field [0001] The invention belongs to the technical field of unmanned ships, in particular to an autonomous navigation system of an unmanned ship and a working method thereof. Background technique [0002] With the rapid development of modern science and technology, the realization of unmanned ships has technical support, and the realization of autonomous navigation of unmanned ships is also possible. 75% to 96% of ship accidents at sea are caused by human factors, and the personnel cost of ship sea operations is high, there is a large gap in the demand for senior crew members, and the living and working space of seafarers accounts for a large proportion of the ship space, which reduces the efficiency of maritime transportation. The unmanned ship effectively solves the above-mentioned problems and is an important part of my country's maritime intelligent transportation strategy. Its autonomous navigation technology is one of the key technologies of the unmanned shi...
