摘　　要：介绍了该系统的整体结构,包括:水下压力获取子系统,船载数据汇聚和传输子系统,以及室内控制和数据记录子系统。然后详细介绍了船载数据汇聚和传输子系统的软硬件设计,它使用了可编程逻辑阵列FPGA和嵌入式操作系统VxW orks,显示出了良好的可靠性、灵活性和可扩展性。With the rapid development of industry and economy, the offshore oil exploration becomes more and more important in China. To provide equipments for China offshore rock stratum exploration ,Time-lapse Marine Seismic Data Acquisition and Recording System is developed. It is the first large scale marine seismic data acquisition system ever developed by China. In this paper the main structure of this system is introduced, including three sub-systems： the Submarine 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 Data Gathering and Transferring sub-System is described in detail, including both hardware and software. It features FPGA （ Field Programmable Gate Array） and embedded operating system VxWorks, shows great credibility, flexibility and expandability.
