| Abstract: | With the rapid development of industry and economy,the offshore oil exploration becomesmore and more important in China.To provide equipments for China offshore rock stratumexploration,Time-lapse Marine Seismic Data Acquisition and Recording System is developed.Itis the first large scale marine seismic data acquisition system ever developed by China.In thispaper the main structure of this system is introduced,including three sub-systems: theSubmarine Pressure Acquisition sub-System,the Onboard Data Gathering and Transferring sub-System,and the Indoors Control and Data Recording sub-System.The designing of Onboard DataGathering and Transferring sub-System is described in detail,including both hardware andsoftware.It features FPGA(Field Programmable Gate Array) and embedded operating systemVxWorks,shows great credibility,flexibility and expandability. |
