Research On Intelligent Ship Damage Control System

Due to the expansion of the scale of naval battles and the appearance of advanced armsand equipment,the threat of naval ships being attacked keeps increasing.In order to ensure thatdamaged ships could still keep their vitality and fighting abilities,a set of intelligent shipdamage control system needs to be set to timely take effective measures to rescue thedamaged ship. Intelligent ship control system can monitor the real-time state of the ship,analyze the damaged ship state, and according to the state of the ship provides feasible losstube measures.Early researches on ship damage control have been done in developed countries.Bycontract,the development of our country still lag behind,which means it is necessary to workon this system.The framework of damage control system was preliminary designed in this paper, basedon the research of basic components and working process of the system.The damage of theship mainly caused by fire and hull damage,so the rescue measures was studied respectivelyaccording to the function of the system.The characteristics of ship fire is different from that of common indoor fires,consequently, the rescue methods and principles are different. The features and rescue methodof ship fire were introduced at the part of research on fair damage control. Then the model offire growth was established based on the principle of zone model. The application of themodel is to calculate fire development with or without control after determining the messageof ship size, fire type, rescue equipment, etc.The state of the ship, such as float state, stability, load condition and so on, must bemastered before taking any rescue steps. On this point the real-time calculation method ofship float state and stability was put forward in this part. Then the principles and the methodsof sink preventing was studied in the light of compartment damage type. Also the recovery ofstability and the righting process was detailed analysed according to the compartment damagetype.Finally, a framework of ship damage control system was developed based on VC++andthe results of the study above. The system realized the real-time display and analysis of theship state and. Then the rescue scheme was presented according to the ship state analysed bythe system. If there was not only one scheme, the system is also capable to choose the bastplan from all the schemes and submit to the user. The change of ship state after damage control will be displayed.Including resistance to sink calculation, centralizer calculation,stability calculation, and the recovery of the ship fire monitoring.
