Abstract

The invention discloses a ship intelligent navigation control system stable and reliable in information transmission, which comprises a ship end system, a communication link, a shore end system and an intelligent monitoring device, and is characterized in that the ship end system and the shore end system realize data receiving and transmitting sharing through the communication link, and a data basis is provided for realizing intelligent navigation, energy consumption management, fault diagnosis and remote control functions of a ship; the communication link comprises a ship-end communication terminal arranged on the ship-end system and a shore-end communication terminal arranged on the shore-end system, and communication link switching devices are arranged between the ship-end system and the ship-end communication terminal and between the shore-end system and the shore-end communication terminal. And the communication link switching device is used for evaluating the quality of the communication link and switching the communication link to the optimal communication link in a manual or automatic mode. The invention further discloses an operation control method of the system.

Description

technical field [0001] The invention relates to the technical field of ship communication and control, in particular to a ship intelligent navigation control system and an operation control method thereof. Background technique [0002] With the rapid development of navigation technology, intelligent ships integrate new technologies such as modern information technology and artificial intelligence. Compared with traditional ships, the intelligence of intelligent ships is mainly reflected in the intelligent navigation functions based on autonomous situational awareness, risk identification and intelligent decision-making. To realize intelligent navigation, the support of the shore base is inseparable, and the cooperation between the ship and the shore is also required. Therefore, the key to intelligent navigation lies in ship-shore information interaction and collaborative control, and efficient, reliable and stable ship-shore intelligent communication is the foundation.

Problems solved by technology

Track control mainly includes track deviation control and steering control. The design of traditional PID rudder and adaptive rudder is only based on tracking and maintaining control of the track, which cannot realize the track control function.

The patent "a method for comprehensive control of the course and speed of an intelligent ship" (ZL202010322872.5) collects the external navigation data of the ship and the internal data of the ship, according to whether the shore-based instructions and data analysis results meet the navigation conditions, and combines the ship kinematics model, fuzzy PID is used to control the ship's course and speed. This method does not consider the influence of the ship's navigation deviation on the course and speed adjustment response time, accuracy and stability; patent "An automatic track planning method for unmanned ships" (ZL202010376077.4) According to the information such as the distance and course of the meeting ship, a collision risk judgment model is established, and the expected course and expected speed of the unmanned ship are obtained through the mixed integer linear planner, so as to avoid the collision of the meeting ship, but the calculation model of this method is complex and does not Consider the impact of size changes of fixed obstacles (such as reefs) on the ship's navigation path planning under different sea conditions

[0006] In addition, in terms of ship-shore information interaction, there are problems such as a single way to obtain information on the shore, few types of information, delays in sending and receiving ship-shore information, and a large amount of redundant information.

The means for the shore to obtain ship information is mainly through the communication equipment on the ship, and the collected information is sent back to the shore. If the ship fails or the communication equipment is not installed, the shore cannot effectively obtain all ship information in the channel, resulting in the shore platform. It is difficult to supervise and control the ship; when the ship is sailing in the open sea, due to the limited bandwidth resources of the communication link, it is necessary to set a time for sending and receiving ship-shore information. The message sent by the shore end cannot be received in time, which may cause serious losses
