A scientific research ship that realizes automatic control of entering and leaving the port

Abstract

The invention discloses a scientific research ship capable of automatic control of port entering and leaving. The scientific research ship capable of automatic control of port entering and leaving comprises a hull; a control system used for automatic control of port entering and leaving is arranged on the hull; the control system comprises a measuring part and a control 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 correspondingly connected with the controller and used for driving the ship to sail; a laser positioning system used for monitoring a ship gradual approaching distance in real time is arranged on a port or a wharf; when an actual ship position parameter reaches a preset distance parameter for automatically controlling ship displacement, a signal of driving the ship to automatically move is transmitted to the automatic control unit; and meanwhile, a signal of stopping manual operation is transmitted to the manual control unit; and the ship is controlled to automatically and stably berth at a preset berthing point. According to the scientific research ship capable of automatic control of port entering and leaving, through real-time signal feedback, a main propeller and a side propeller can be accurately controlled, and the accuracy of the final berthing position of the ship is realized.

Description

Technical field [0001] The invention relates to the technical field of ship control, and in particular to a scientific research ship that realizes automatic control of entering and leaving a port. Background technique [0002] Ships need to carry out mooring and berthing operations when arriving and leaving the port. This work has certain risks and is a critical operation of the ship. Some existing ship berthing requires the command of pilots, and some requires experienced captains. There is no unified berthing method. In the automotive industry, the berthing of cars is monitored through ultrasonic waves and completed through left and right mirrors. docking, but ships are larger than cars, and the docking method of cars can only be used at short distances. The surrounding docking environment is simple, and ships are parked far away from the dock. This method similar to cars cannot meet the requirements. In addition, the ship also needs to consider wind and wave currents dur...

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
