Design for the Emergency Command Information System Architecture of Ocean Oil Spill

On the basis of defining the Ocean Oil Spill Information Services and in order to improve the efficiency of disposal and command of more frequent ocean oil spill accidents, the SOA (service oriented architecture) and P2P (peer-to-peer) are utilized to design the physical framework and functional framework of the emergency ocean oil spill command information systems. The goal in this is to study the composition and structure of each framework. The emergency command information system of ocean oil spill is built on C⁴ISR (command, control, communication, computer, intelligence, surveillance and reconnaissance) architectural framework that is composed of command view, system view, and technology view. The physical framework of the command information system architecture is characterized by a multi-layer structure. The node is divided into LSP (local service peer), GSP (group service peer) and CSP (common service peer). Each system and software set can be encapsulated as part of the Ocean Oil Spill Information Services, with each service being capable of serving as a local service node. Furthermore, each local service node participates within a peer group. According to the service purpose and granularity, the functional framework is divided into physical resource layer, data layer, support service layer, application layer. Data layer mainly includes communication protocol, message format, data type, and various database, etc. Support service layer includes storage management service, information distribution service, service management, human-computer interactive service, resource sharing service and information security service, etc. Application layer includes situation generating service, emergency plan service, emergency command service, emergency assessment service, communication support service, navigation and positioning service, etc. We draw conclusions that the information system architecture proposed in the paper has more prominent reliability and flexibility through contrastive analysis of similar information system architecture, and lay foundations for research intoocean oil spill service-oriented command information systems.
