基于IXP422的海气边界层数据采集器的设计

Design of air-sea boundary layer data collector based on IXP422

海气边界层对海洋气候有着巨大影响,是中长期数值气候变化预测的理论基础。以Intel XScale IXP422作为主控制器,构建并移植适合其硬件结构的嵌入式Linux操作系统,研发出一种可实现海气边界层监测系统数据采集、处理和转发等功能的数据采集器。详细介绍了海气边界层系统架构、采集器的软硬件设计。采集器充分利用Linux完善的TCP/IP协议和丰富的接口资源,具有多任务处理性能,并省去了上位机的环节,可实现无人值守。

The air-sea boundary layer affects the marine climate strongly.It is the theoretical basic for forecasting the climate change.A new kind of data collector with the functions of air-sea Boundary Layer monitoring system data collection,processing and forwarding has been developed in this paper.The Intel XScale IXP422 was selected as main controller.The hardware-structure-fitting embedded Linux operating systems was constructed.The focus of this paper is mainly on the air-sea boundary layer system frame and the software and hardware design of the collector.The collector takes advantage of Linux improved TCP /IP protocols and abundant interface resources,with multitasking performance.The whole system need not use a computer,enabling unattended.
