Research On Integrated Plat Information System And Some Key Technologies

Integrated plat information system(IPIS) is an integrated system in the platform of implementing information management, comprehensive monitoring, system control and security. IPIS integrate functions of the scatter equipment about monitoring and control to build a set of monitoring, operation, etc, in one highly informatization and automatization integrated system and achieve control automation of the platform. Research on key technologies about IPIS can enhance the economics and safety of offshore platform. In the paper deep research on key technologies has been done of the IPIS about the architecture、 network integration、distributed database and so on. The main research contents and works as follows:1、From the view of overall design of the system,the paper analysis the basic functions of IPIS, composed of elements of information flow, connections, hierarchical planning and design specifications. A system of three-dimensional system of offshore platform architecture is established that is information architecture, system architecture and technical architecture. Information architecture platform classify all kinds of information to make clear the flow of information, given the information flow. System architecture information architecture defined tasks into a series of system function modules and connections between the module and the module to make the definition; technical architecture defines the system design to follow minimum standards and conventions. The architecture of IPIS is first put forward in this paper which gives theoretical framework for system design.2、The design technology of the platform integrated network is studied. Several typical platform network structures are analyzed and compared. The design of the integrated network system based on the Auto Net drilling platform is completed including network structure design, network node hardware and software, redundancy design and reliability design.3、The control network of drilling platform based on Auto Net is designed. Firstly the control network structure is given. Then, the design of the regional nodes and the design of the PPC module are carried out with the platform of the drilling platform as an example. As the same time, the function module of the real-time data monitoring is designed so the data monitoring of the thrust system and the power system in the power positioning system is realized.4、Distributed database technology is studied. The distributed database structure, the server database structure, the database concept model, the relational view of the database function module is designed. The sharing, monitoring and management of the data information of the drilling platform system is realized.
