Product introduction of straight wing rudder propeller control system
Product Overview:
JNZYDJ type control system is suitable for ships with straight-wing rudder propeller propulsion and rudder control. The control system can precisely control the ship, and the thrust and direction of the straight-wing rudder propeller can be precisely controlled. It is suitable for good maneuverability and dynamic positioning function of minesweeper ships, landing ships, offshore platforms, official ships, tugboats, engineering ships and passenger ferries.
The system has the characteristics of high degree of automation, flexible operation, sensitive response and good reliability, so that the ship not only has good maneuverability, but also can perform various complex movements such as lateral movement, in-situ rotation, and reverse sailing as required.
For dynamically positioned ships, the computer positioning system can send control commands to the straight-wing rudder propeller to adjust the magnitude and direction of the thrust, and to precisely control the ship.
Main function:
??  Start-stop function: local/remote control with start-stop function
??  Control switching: local/remote switching, local priority is higher than remote control
??  Forward, reverse and steering controls
??  Pan left and right and swivel maneuvers
??  Fault alarm record and query
??  Automatic return to origin function when power on
??  Duplex or independent operation
??  Advance stepless speed control
??  Remote control to local speed hold function
