中国科学院中国近海海洋观测研究网络主体由数十个海洋观测浮标系统构成,它们散布在中国近海,可进行海洋要素的长期连续定点观测。为了实时了解海洋环境动态变化信息,需要将观测数据实时传回位于陆地的陆基支撑数据接收站,以便科学家进行数据处理和分析。实时数据传输采用GPRS和CDMA无线通讯方式与“北斗”卫星通讯方式,形成了一个覆盖中国近海的多方式大范围数据传输网络,实时的将观测浮标系统观测数据和状态信息传送到陆基支撑数据接收站,在陆基站编制安装了数据接收软件,将实时观测数据予以接收和显示。另外,为了更好的发挥数据功效,需要对原始数据进行整理入库,形成初级数据产品,并进行网络信息发布,建立数据共享机制。这里采用成熟的数据库软件,建立了实时数据库和延时数据库,它们具有丰富的数据查询功能,同时建立了基于Internet的数据信息发布与交流系统,可向科学家、政府决策者、海水养殖企业和公众用户等提供不同层次的数据信息产品服务,并为其提供一个信息交流平台。
The CAS China CNOOC network is composed of dozens of marine observing buoy systems scattered in offshore China and capable of long-term continuous point observations of marine elements. Real-time knowledge of the dynamics of the marine environment requires the real-time transmission of observations to land-based land-based support data receiving stations for scientists’ data processing and analysis. Real-time data transmission uses GPRS and CDMA wireless communication and “Beidou” satellite communication mode to form a multi-mode large-scale data transmission network covering the offshore of China. Real-time observation data and status information of observation buoy system are transmitted to land-based Support the data receiving station, in the land base station compiled and installed data receiving software, real-time observation data to be received and displayed. In addition, in order to better play the effectiveness of the data, the need to organize the original data warehousing, the formation of primary data products, and network information dissemination, the establishment of data sharing mechanism. Here mature database software is used to set up a real-time database and a time-delay database. They have rich data query functions and meanwhile establish an Internet-based data information release and exchange system that can provide scientists, government decision makers, mariculture companies and the general public Users provide different levels of data information products and services, and provide an information exchange platform.
