* 产品描述

产品描述:
控制单元R&S NetCCU®800(图1)在新一代R&S®NH/NV8200电视发射机[1]和VHF调频发射机R&S®NR8200新系列[2]中都包含作为通用分配中心。对于网络运营商来说,这样做的好处是操作和培训成本较低,并且简化了备件库存方面的物流。电视和调频发射机的控制概念和用户界面首次统一。这也简化了他们对网络管理系统的集成,便于设置和投入使用,并降低了维护和服务成本。


发射机系统主要由励磁器、放大器、冷却系统和发射机控制单元组成。根据输出功率或冗余概念,这些组件以多个形式存在。中央控制单元(CCU)的任务是显示系统参数,监控它们并在发生错误时执行冗余切换。为了最大限度地提高性能,R&S NetCCU®800通过以太网与激振器连接,并通过CAN总线与放大器连接(图2)。


直接的菜单提供访问所有参数的发射机系统。您可以调用设置范围和每个参数的简要说明;这尤其有利于系统的偶尔现场使用(图3)。


由于R&S NetCCU®800使用Javasoftware和XML描述语言,菜单可以很容易地适应客户的特定需求(例如其他语言)。


除了越来越重要的无人值守站的远程控制外,网络运营商的网管系统可以直接与控制单元连接,并与其集成的SNMP代理进行通信。代理通过SNMP trap自动通知控制中心发射站的错误。CCU还配备了一个web服务器,为通常在不同站点的维护人员提供通过标准web浏览器随时随地访问发射机系统的所有参数(图4)。菜单的结构和内容与通过显示器显示的发射机的本地操作相同

Product Description:
The Control Unit R&S NetCCU®800(FIG 1) is included as a common distributing center both in the new generationof R&S®NH/NV8200 TV transmitters [1]and in the new family of VHF FM Transmitters R&S®NR8200 [2]. For networkoperators, this has the advantage of lowoperation and training costs as well assimplified logistics with regard to stockkeeping of spare parts. For the first time,the control concept and user interfacesin TV and FM transmitters are uniform.This also simplifies their integration intonetwork management systems and facilitates the setup and putting them intooperation, plus reduces maintenanceand service costs.


A transmitter system mainly consistsof an exciter, amplifier, cooling systemand transmitter control unit. Depending on the output power or redundancyconcept, these components are present in multiples. The central controlunit’s (CCU) task is to display the system parameters, to monitor them andto perform redundancy switching in theevent of an error. To maximize the performance, the R&S NetCCU®800 is connected with the exciters via Ethernetand with the amplifiers via a CAN bus(FIG 2).


straightforward menus provide access toall parameters of the transmitter system.You can call up setting ranges and abrief description for each parameter; thisespecially facilitates the system‘s occasional on-site use (FIG 3).


Since the R&S NetCCU®800 uses Javasoftware and the XML description language, the menus can easily be adaptedto customer-specific requirements (e.g.other languages).

In addition to the increasingly importantremote control of unattended stations,network management systems of thenetwork operator can be directly connected with the control unit and communicate with its integrated SNMP agent.The agent automatically informs the control center about errors on the transmitter station via SNMP trap. The CCU isalso equipped with a web server, providing the maintenance personnel, whichis often at different sites, access to allparameters of the transmitter systemvia a standard web browser when andwhere needed (FIG 4). Structure andcontent of the menus are identical to thelocal operation of the transmitter via display
