Problems solved by technology

When the ship turns, the rudder deflects at an angle, the hull advances in oblique water flow, and the resistance of the ship increases significantly compared with straight-line sailing. At the same propeller speed, the ship speed will decrease, and the characteristic curve of the propeller will become steeper, which may cause main engine row. Increased smoke temperature, incomplete combustion, and overloaded mechanical load may cause damage to the cylinder liner and cylinder head of the main engine in severe cases

Abstract

The invention relates to a ship motion and engine push network control simulation system comprehensively taking factors of ship steering and main power plants into consideration, mainly comprising the following six parts: a ship motion virtual reality simulation scene, a three-dimensional ship diesel engine motion model, an automatic steering system, a central control room engine remote control system and steering table engine remote control unit, a system call server and a DCOM group communication unit, wherein, the first five parts conduct data intercommunication respectively through the DCOM group communication unit. The system of the invention can improve the ship motion control effect, facilitate the prevention of diesel engine overload, increase the reliability and the economical performance of the power plant and improve the precision of the simulator and training level of sailors.

Description

Technical field [0001] The invention relates to a ship motion and main engine propulsion network control simulation system which comprehensively considers two factors of ship steering and main power device. Background technique [0002] As an important tool for maritime transportation, the ship's main power plant and course control system have been completely independent for a long time. In fact, the control of the ship's main power plant is closely related to the ship's movement. The higher the relative speed, the more obvious the rudder effect. When the speed of the ship is high, the control effect of the steering is significant; when the ship is berthing or unberthing, the speed of the ship is usually low. At this time, it is still necessary to frequently control the speed of the main engine so that the propeller generates water flow relative to the rudder blades to ensure the steering effect and obtain Good boat handling characteristics. The efficiency of the marine di...
