Ship attitude intelligent control system and method thereof

Abstract

The invention discloses an intelligent ship attitude control system and method. The system comprises a programmable controller, a tilt angle sensor, a high-pressure water pump, a water pump variable-frequency speed regulation device, a water pump angle regulation device, a water pump position regulation device and a water supply pipeline, the tilt angle sensors are symmetrically arranged on the two sides of the deck and connected with the programmable controller. The attitude change of the ship body is detected through the tilt angle sensor, the programmable controller makes an intelligent decision, the position of the high-pressure water pump and the water spraying direction, pressure and speed are changed through the water pump position adjusting device, the water pump variable-frequency speed adjusting device and the water pump angle adjusting device, and torque opposite to the attitude change of the ship is generated; therefore, the working posture of the ship is accurately kept. The system is high in response speed, high in angle accuracy, good in flexibility and stability, small in mass and size, high in portability and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of balance and stability of water machinery and equipment, and relates to an intelligent control system and method for a ship attitude. Background technique [0002] Water machinery and equipment are all tools that are created by human wisdom and modern industry to assist human beings to complete a certain work on water. Among them, the more developed ones are various types of ships, such as passenger ships, transport ships, warships, pumping and sand pumping ships, yachts, motor boats and so on. In terms of resisting the adverse effects of the external environment, water machinery and equipment are much more vulnerable than those on land. For some water machinery equipment with lifting function, when the crane lifts heavy objects, the equipment tilts and cannot exert the maximum lifting capacity; for some pumping and sand pumping ships, due to the gravity of the output water and sand pipeline, the hull dev...

AI Technical Summary

Problems solved by technology

However, this device has the following defects: 1. The system is complex and cannot realize intelligent automatic control; 2. The water inlet and outlet of the water pump are on the same side of the hull and are close to each other, and the suction force produced by the water inlet and the recoil force produced by the water outlet are matched. Offset, reducing the balance efficiency of the hull; 3. The outlet angles of the two equipped water pumps are fixed, and the recoil force relative to the direction of the hull cannot be changed, so it cannot continuously provide the recoil force in the direction of the maximum efficiency of anti-heeling; 4. The longitudinal inclination of the hull cannot be adjusted

Its disadvantages are: 1. Due to the large number of ballast side tanks, it takes up a large space inside the hull; 2. Due to the large amount of water required to achieve balance, it will increase the load of the ship, so it will bring unnecessary energy consumption
