The present invention provides an automatic control method and system for intelligent ship rudder equipment. The method includes: obtaining a rudder angle setting instruction and judging whether the rudder angle setting value in the rudder angle setting instruction is within the deflection range of the rudder equipment; If the angle setting value is within the deflection range of the rudder equipment, start the hydraulic pump motor and the hydraulic pump to make the steering gear rotate; when the steering gear is in a stable rotation state, judge whether the rotational angular velocity of the rudder blade is greater than the speed threshold; if the rotational angular velocity of the rudder blade If it is not greater than the speed threshold, it is judged whether the rotation angle of the rudder blade reaches the set value of the rudder angle; if the rotation angle of the rudder blade reaches the set value of the rudder angle, the hydraulic pump motor and the hydraulic pump stop, and the execution of the rudder angle setting command is completed. The invention realizes the speed control of the rudder equipment when turning the rudder, avoids the damage of the rudder gear and rudder blades caused by the excessive rotation of the rudder equipment, realizes the limitation of the angle of the rudder equipment, and avoids the over-limit angle given by the decision-making error of the intelligent ship decision-making mechanism Cause damage to the steering gear and the transmission mechanism of the rudder.
Description
technical field [0001] The invention relates to the technical field of intelligent ships, in particular to an automatic control method and system for intelligent ship rudder equipment. Background technique [0002] Smart ships refer to the use of sensors, communications, Internet of Things, Internet and other technical means to automatically perceive and obtain information and data on the ship itself, marine environment, logistics, ports, etc., and based on computer technology, automatic control technology and big data processing and analysis technology , to achieve intelligent operation of ships in terms of ship navigation, management, maintenance, cargo transportation, etc., so as to make ships safer, more environmentally friendly, more economical and more reliable. [0003] The rudder equipment in a ship refers to the general term for the related devices that use the rudder to keep the ship on the desired course, change the original course or perform gyrating motion durin...
