 主要特点：  

BentlyNevadaTM ADRE 408 DSPI
        ? 新的Sxp软件平台与BentlyNevadaTM硬件设备的结合
        ? 多通道，，迅速灵活的数据采集解决方案
        ? 可在现场独立运行
        ? 与以太网兼容，可远程浏览及远程操作，节省差旅费用

该数据库可进行分布式的数据采集，能在多种环境下运行，具备高效的数据存储方式，具有丰富的客户端数据处理和分析工具，可扩展的数据协同应用，并且提供ODBC/JDBC/OLE DB接口以及工业标准规范OPC和DDE，提供图形化的应用开发界面，支持WEB访问维护，提供报表开发工具等特性，所以成为企业底层控制网络和上层管理信息系统网络连接的佳选择。该实时历史数据库是一个模块化软件系统，主要分为客户端模块和服务器端模块，客户端模块负责实时数据的采集，服务器端模块负责数据采集设置、压缩和存储等工作。

        对于浙大中控的七套DCS系统，由于浙大中控具有OPC接口，提供OPC Server，因此直接在DCS工程师站安装实时历史数据库的OPC 连接器( Client)进行数据采集。

        对于横河系统，由于不方便直接在现场安装客户端，因此，在另外一台机器上安装GE的OPC中间件 OPC tools，对横河OPC Server 来讲，它是OPC Client，对于实时历史数据库，它又是OPC Server，只要在该机上运行横河的OPC配置文件，就能够自动到横河DCS中采集数据。这样做有两个好处，一是能够***DCS操作安全，二是当DCS与IH服务器的通信中断时，接口机将保存数据，并在通信正常时再将数据送至IH服务器。

For years, farmers and renewable power companies have debated which land use is more sustainable – farming or clean energy. Few have considered the possibility that the two could have equal value, much less coexist.Yet, a small-but-growing U.S. agrovoltaic industry is looking to change things. By turning solar grounds into pastures for sheep and other livestock, both farmers and power companies can benefit. Plus, the collaboration requires half as much land.In other parts of the country, farmers are installing wind turbines in their fields and pastures. These behemoths pump water and generate electricity to save farmers money, generate clean power, and help the planet. Wind installations don’t disrupt crops or livestock, either, so farmers can easily integrate them into existing plots to effectively conserve space.So, should the U.S. dedicate more land to renewable energy?First, you must define “land.” Is it a brownfield or nature reserve? If it’s unusable as is, installing solar panels and wind turbines might be an excellent solution. However, if the land has intrinsic value or is still of some use, planners might want to think twice about clearing and developing it.Ultimately, dedicating more land to renewables could help the U.S. – and the entire planet – replace fossil fuels, minimize carbon emissions, and quell climate change. However, doing so may also indirectly intensify land competition elsewhere in the world to meet global food demand.
