This invention discloses an intelligent
CTD sampling control method and
system combining
tidal current prediction, relating to the field of marine observation technology. The method includes: generating
tidal current predictions by fusing historical tidal elements and numerical model outputs, and planning candidate sampling windows; real-time acquisition of multi-source
observation data to form standardized observation vectors, calculating the deviation from the predicted values and fusing the
vertical shear force
intensity factor to perform rolling corrections on the predictions and update the sampling windows; comparing real-time
observation data with safety thresholds to generate operational access instructions, issuing control instructions under permissible conditions, and dynamically adjusting sampling parameters and triggering
resampling based on profile
data quality coefficients; synchronously monitoring abnormal events, triggering emergency
recovery, and deferring the task to subsequent candidate windows. By constructing intelligent closed-
loop control, introducing
vertical shear force early warning, and a
parallel processing architecture, adaptive, highly safe, and highly reliable
CTD sampling operations under complex sea conditions are achieved.
