The Fpso Multi-level Automatic Monitoring Network Communication Research

This thesis is derived from the sub-subject:"totally closed high-speed message highway automatic network system of FPSO " of ((" one dragon" project of indraught - digesting and assimilation of great technology in the 9th five-year country plan)) made by the State Economic and Trade Commission and another sub-subject :"the design and further development of BINGO 9000 semi-submersible drilling platform information system" of (( the high-tech demonstration engineering project of country )) made by State Planning Commission.The multi-system network communication of FPSO is mainly researched and the SQL database is also designed, the ADO database accessing interface technology is used to query the measured information, the communication procedure of network is developed using Socket, it can carry on real-time signal monitoring and data transmission between server and client; the parameter monitoring system of cargo oil tank in the FPSO oil carrier and fuel loading and heating monitoring system of BINGO 9000 type oil drilling platform are also investigated, the two system are made up of signal measurement, data acquisition., data display- database inquiry and network communication etc; the design method and programming environment of monitoring software are studied in this essay, the cargo oil and fuel system monitoring software are also introduced; In order to real-time dynamically display the signal's changing of oil level , temperature, pressure and current, the graphic interface is designed under the VC environment. It has been validated that the software can meet the demand and its interfaces are comprehensive- sensible and easy to operate.On the basis of hardware terms of laboratory, applies the data acquisition board to complete multi-parameter gathering and data processing experiment, FPSO multistage monitoring system which consists of cargo oil, ballast, machine, fire and gas etc. and network transmitting are validated , it is indicated that this systematic software design operates well, security, stability, the performance meats the requirement too.
