Abstract

The invention discloses an electrical control system and method suitable for an air layer resistance reduction ship. The electrical control system comprises a control center, and a plurality of air layer thickness measuring instruments, an air supply device, an air supply pipeline and a control valve set which are electrically connected to the control center; the output end of the air supply device is communicated with the input end of the air supply pipeline; the output end of the air supply pipeline is communicated with a plurality of air nozzles arranged at the bottom of the ship body. Thecontrol valve set is arranged on the air supply pipeline and used for controlling the ventilation capacity of the air supply pipeline. The air layer thickness measuring instruments are uniformly distributed at the bottom of the ship body, are in electric signal connection with the control center and are used for detecting air layer thickness parameters and outputting the thickness parameters to the control center. The control center is used for receiving and processing the parameters and outputting control signals to the air supply device and the control valve set, adjusting the power of theair supply device and the opening degree of the control valve group when the parameters are not in the preset range or the expected estimation is not in the preset range,, and controlling the air quantity of the air supply device and the ventilation quantity in the air supply pipeline to enable the parameters of the air layer to be in the preset range.

Description

technical field [0001] The invention belongs to the field of electrical control of ships, and in particular relates to an electrical control system and method suitable for air layer drag reduction ships. Background technique [0002] Marine air layer drag reduction technology, through a specially designed device, ventilates to the bottom of the ship, forms and maintains a layer of air layer on the bottom of the ship, isolates the bottom surface of the ship from water, reduces the wet surface area, and can significantly reduce ship resistance and fuel consumption . [0003] However, the ship sails in complex sea conditions, and the ship's navigation attitude is constantly changing under the action of wind, wave and current, so the influence of wind, wave and current on the air layer drag reduction system must be considered. In the real sea state, due to the wind and waves itself and the rolling of the ship, the gas is easy to escape, and it is difficult to form a stable gas ...
