The deep development of information-integration of ship security changes the need of ship security platform. The integration of ship security equipment and security system becomes a problem urgently to be solved in ship safety construction. In view of this, this paper proposes the design of integrated architecture of ship security platform based on SOA. EJB components will be used to develop the system and WSDL will be applied to describe the architecture integration interface. Added that each process of service designs is using the clustering algorithm, it aims to achieve an integrated architecture of ship security platform based on SOA, and also shows the algorithm implementation of service integration of ship safety management platform. The research proves that it can realize a seamless integration of ship safety equipment and other ship safety information system in digital ship. It effectively solved the problem that ship security platform information resources cannot be shared each other, and can be applied in the weapon platform ship information security system practically.
