Abstract Ship damage control, is when the disasters such as fire, leaks and others happened onthe ships,the crews take actions to prevent,limitate or respair these disasters to make theextent of the damage to the ship is reduced to a minimum and the ships can resume normaloperations as soon as possible.when the disasters such as fire, leaks and others happened onthe ships,ship damage control system can monitor these disasters first and alarm to thecrews,then the workers can exclude hazards correctly.However,most of the damage controlsystems always alarm unintelligently,which wastes a lot of human resources and time andresults in low efficiency.From the above analysis we can know that the intelligent shipdamage control system will become the mainstream in the future but the penetration aboutthe field in our country is not very high.In this paper, we will design the ship damage control system.The system can send soundand light alarm and display the types and the positions of the disasters at the same time whenthe disasters happened.According to the actual situations the system can decide whether toaccess to the alarm bell system and take actions to eliminate the disasters automatically ornot.This paper mainly includes two parts of hardware and software.The hardware part of thesystem is mainly used tosintroduce and choose the next bit machine like power supply unit,the CPU ,signal unit, communication unit of S7-1200PLC and so on.In this design,we shouldmonitor the fire and flooding disaster on the ship so that we also introduce the type oftemperature sensor, smoke sensor and water immersion sensor.We draw the picture ofhardware wiring diagram between them and PLC.The software part is mainly to programefor the whole control system and design the HMI.We use TIA PORTAL V13 to programe,theprogramming language is Ladder diagram.The design finally complete the preparation,compile and simulation of the program andthe experiment proved that the system is stable and reliable operation, and it can meet thedesign requirements.
