基于XML的实时海洋数据传输网络系统

近年来,在海洋灾害预测、预报等海洋信息产品的开发中,对准确、大量、连续、实时的海洋要素监测数据的依赖性日趋增强。同时,由于海洋数据的复杂性,数据来源的多源性,数据平台异构,数据格式不规范等原因,增大了数据集成的难度,降低了数据使用的效率。文章提出了用XML作为传输媒介,结合Socket网络通信技术,建立实时海洋数据传输网络系统,实现了海洋数据集成与交换格式的统一,屏蔽了影响海洋数据集成和使用效率的因素。文章对XML在海洋信息产品开发中的应用做出了有益的探索和尝试,旨在促进XML在我国海洋信息领域的应用。

THE SYSTEM OF THE REAL TIME MARINE DATA TRANSMISSION NETWORK BASED ON XML

The necessity to access the ever greater quantities of marine data to support a broad range of marine information products,including ocean disaster prediction and forecast,has been increasing rapidly over the recent years. At the same time,the capability of data integration and the data use utilization in marine information fields have not achieved for such needs. This was mainly caused by the complexity of marine data,the multiformity of data source,the difference of the information platforms and the nonstandard format of data. To overcome these problems,authors proposed a structure of the system of the real time marine data transmission network based on XML combined with Socket interface. The system unified the format of data integration and data exchange,shielded the effect factors of data integration and the data use utilization. Authors commit themselves to apply the XML to the development of marine information products,aiming to boost the application of XML in national marine information fields.
