The invention relates to the technical field of
ship control, in particular to a
fishing boat
control system based on
data analysis, which comprises a traction
load analysis module, a fluctuation condition division module, an attitude disturbance
estimation module, a propulsion
power regulation module and a
rudder angle correction output module. According to the method, by analyzing the traction force load sequence value and the moment arm length of the
fishing net traction point, calculating the left and right side offset torque and marking the action direction, the attitude adjustment precision of the ship is optimized, the operation sea condition level is adjusted according to data, and the ship can be subjected to more reasonable attitude
estimation and adjustment under the dynamic working condition; the wind pressure change rate and the
pitch angle rate are combined to judge the direction
resultant force trend, and the navigation attitude is adjusted according to the sea condition grade, so that the ship can more accurately
resist the influence of sea surface
storm waves and maintain the course stability, and the
rudder angle is corrected by adjusting the propulsion power in real time, limiting the adjustment amplitude of the propulsion power and correcting the
rudder angle according to the real-
time data of the navigation attitude. And the
propulsive efficiency and the navigation precision are optimized.
