Control system for assisting ship to enter and exit port by utilizing DP

Abstract

The invention discloses a control system for assisting a ship to enter and exit a port by utilizing DP. The system comprises a measure part, a control part, a power part and a thruster part, the control part comprises a controller, a manual control unit, an automatic control unit and a computer software system, wherein the manual control unit and the automatic control unit are connected with the controller and used for driving a ship to sail, a laser positioning system which is connected with the control part through a wireless signal and used for monitoring the gradually close distance of the ship in real time is arranged on a port or a wharf, when the actual ship position parameter reaches a preset distance parameter for automatically controlling shifting of the ship, a signal for driving the ship to automatically shift is sent to the automatic control unit, and meanwhile, a signal for stopping manual control is sent to the manual control unit, so that the ship is controlled to automatically and stably stop to a preset stopping point. According to the system, accurate control on a main propeller and a side propeller can be realized through real-time signal feedback, and the accuracy of the final stopping position of the ship is realized.

Description

technical field [0001] The invention relates to the technical field of ship control, in particular to a control system that utilizes DP to assist ships entering and leaving ports. Background technique [0002] Mooring and mooring operations are required for ships to arrive and leave the port. This work has certain risks and is a key operation of the ship. For the berthing of existing ships, some need to be commanded by pilots, and some need to be completed by experienced captains. There is no unified berthing method. In the automotive industry, the berthing of cars is monitored by ultrasonic waves and completed through left and right mirrors. Docking, but the ship is bigger than the car, and the car's docking method can only be used in a short distance, and the surrounding docking environment is simple, while the distance between the ship's berthing and the dock is relatively long, and this method similar to the car cannot meet the requirements. In addition, the ship needs ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents record the existing technologies related to automatic berthing. From the above-mentioned disclosed technologies, since the wind speed, current, and wind and waves have the greatest impact on the ship when the ship is docking, and the wind speed, current, and wind and waves change in real time, In this case, regardless of the use of signal detection, magnetic control or claw assistance, it is impossible to achieve fast, safe, stable and precise control of the ship when it docks, and it is also impossible to achieve automatic entry and exit without human operation. It has become a major problem restricting the rapid, safe and stable entry and exit of ships
