SYSTEM OF SHIP AUTOMATIC CONTROL Russian patent published in 2012 - IPC B63H25/04 

FIELD: transport.

SUBSTANCE: invention relates to facilities for vessel movement automatic control and dynamic vessel positioning. Suggested system implements maximum synergy of complex application of number of various vessel positioning facilities equipment, completeness of environmental perturbations measurements and use of one and all propelling vessel systems and devices as control objects. Suggested system comprises: vessel movement parameters metres unit, external influence sensors unit, control objects unit, computing unit, control unit. Navigation module in vessel movement parameters metres unit includes differential versions instrumentation of GPS and "GLONASS" navigation satellite systems, inertial position navigation system instrumentation, radio navigation systems instrumentation, hydroacoustic navigation systems instrumentation and radiogeodesic systems instrumentation. External influence sensors unit contains current and tidal influence parameter sensors in addition to wind and waves influence parameter sensors. Control objects unit includes main propellers with water screws of adjustable speed or adjustable pitch, steering gear, engines of maneuvering devices of "screw in pipe" type, turning engines of adjustable speed or adjustable pitch for turning propeller-steering columns with corresponding sensors of control actions. Control unit is made as ship-driver module and contains control and monitoring unit.

EFFECT: system functionality enhancement with simultaneous increase in accuracy and reliable informativity through determination and processing of parameter redundant measurements by complex instrumentation which in its turn provides improved system functional reliability and navigation safety.
