摘　　要：海上高精度三维地震数据采集对室内系统数据处理提出了更严格的要求,该文提出了一种海上高精度地震数据采集系统中央控制板的嵌入式软件设计与实现方案。该软件运行于Vx Works操作系统,采用模块化设计,数据传输部分采用基于CPCI(Compact PCI)总线架构的DMA(Direct Memory Access)传输方式。在数据处理过程中,采用多任务方式同时对4条拖缆进行数据转存。实际测试表明该系统设计具有高效的性能,满足高实时性、高可靠性及高效传输性。High-accuracy 3-D marine seismic data collection,which has more rigor requirements for indoor data pro- cessing system. In this paper a scheme of the design and implementation of the embedded software is proposed, which is based on the central control board for high-accuracy seismic data collection system at sea. The proposed method runs on the VxWorks operating system,uses modula~ design that adopts DMA（Direet Memory Access） trans- fer program,which belongs to CPCI（Compact PCI） bus architecture. In the course of data processing,the data trans- mission mechanism of the system can operate 4-wire data transmission. The experimental results demonstrate that the software system has good performances,which can satisfy the demand for real-time,high reliability and efficiency.
