DK8000 F3多用途高清接收机 说明书

DK8000 F3多用途高清接收机 说明书

DK8000/F3多用途高清接收机F3本机的真正型号是DK8000,史上接收能力最强的国标地波功能;卫星、有线、地而三种信号接收,类似单反相机的机身。

F3共有三种主板:全配置的家用机标准主板DK8000、减配的家用机主板DK8000一New(或DK8000一N)、工程机主板DK8000-ASI。

1年多的研发,10种以上派生璎号,100余次升级,近l000项改良、今年底,F3的硬件和软件终于食埃落定,实现了预定的目标。

F3对于我们之所以那么重要,是因为它完全由国人自己打造的,价格不到进口机的一半,从而摆脱对老外的依赖它证明了我们有能耐没计出适合同情的顶级高清机。

要说F3超越进口机型的地方,包括搭载大陆和港台三个标准中文字库并闩动转换;史上接收能力最强的国标地波功能;卫星、有线、地而三种信号接收井无缝换台;模块化设计以及小锅菜销售理念等等,实在太多太多了……型号组合而搭载在主机上的活动调谐板,就相当于单反相机的镜头。

通过不同的调谐板与主板组合,实现不同的功能。

而F3XX其实就是调谐板的型号,它是根据调谐板上的硬件而定的。

F3家用机目前有两种主板,除了最早的标准主板(简称大板)之外,还有一款精简主板(简称小板)。

它是在标准主板的基础上,去掉不常用的双C1功能,去掉板载卫星调谐器,主板面积比标准板减小l/3。

精简版的好处是腾空原来拥挤的箱内空间,便于玩家自己安装内置硬盘,还预留了12V和5V电压插座,预留了后背安装排热风扇的位置,但去掉了eSATA硬盘接口和同轴音频接口。

小板依然是4层PCB板,采用新的镀金工艺,改善了化孔和贴片的可靠性。

小板上没有卫星单元,为此专门设计了一款新的调谐板,搭载两个调谐单元。

一个是全新的高拓DMB-TH/DVB—C无线有线接收单元,另一个是全新的二代易迩达DVB—S2卫星单元,同样采用镀金的4层PCB板。

小板搭载F307调谐板之后,最大功耗仅12瓦,待机l0瓦,售价也降低很多。

CYLINK公司AIRLINK产品说明无线频率信号的路径基础什么是路径天线到天线视线和适当的距离自由的空间没有路线的障碍路径是射频信号由一个单元到另一个单元天线传输的环境一条线路地点A和地点B之间当你能从这个点看到哪个点时这条线路是可行的,这情形一般被称做“可视路线”和一条具备了成功与稳定的线路。

线路通常穿过空旷的自由空间,但是穿过任何事物包括墙壁和建筑物。

无线电信号在传播时消耗它们的能量。

但是在自由空间里衰减的能量都是可以预料的,因为无线电频率信号能量损失在一定距离成一定比例。

任何阻碍都会使线路信号在无法预料的情况下损失。

一条线路之间有障碍物就不是一条好的线路。

路径中在遇到大的障碍物如:山脉,高大的建筑物,大片森林或者天线间的距离非常遥远都是不通的。

一条线路之所以不通是因为障碍物或者距离过远。

在特定的地点增加一台或者更多的中继器或者增加天线的高度是实用的。

中继器可使路径绕开障碍物,或者是一个较长的路径分成较小的段。

地球的凸出地球的曲率天线的高度因为地球不是平坦的,当计划路径超过7英里,地球的凸出在无线电频率信号里会形成一座山形障碍物衰减线路信号。

克服地球凸起部分的障碍,天线必须设在高于地球平坦地方的高度。

较长的线路需要增加天线的高度。

需要增加天线的高度使用的公式为:增加高度=距离2/8路径的距离单位是英里增加高度的单位是英尺费尼尔半径由于无线电信号比可见光频率低,不能象激光或光线那样在两点传输不损失信号,无线电信号在空间传输需要占领大量的空间,这个象雪茄一样的区域是从天线的一端到另一端的天线形成的。

在次区域的实际支流,在这个路径的7英里处可以出现信号,达不到便接受不到信号。

因为地球的凸出会对信号有较多的障碍。

为了避免这些障碍,必须使天线在足够的高度,并且允许第一个费氏半径不受地球凸起的阻碍或其它障碍物。

事实上,我们已经发现,假如只有60%的福森区域是可以通过这个障碍物,那么福森区域基本上是相等的,都可以通过。

由第一个60%的福森区域做标准,用于计算线路。

用0.6F1为计划标准,可以用以下公式:高=4.339[(距离/4频率)的根号]这儿的D是线路的距离单位是英里F是频率用频率单位赫兹.并且受高度的影响H是用英尺见于有些线路,实质上是在平滑的地带(没有障碍)天线高度的最底限度计算用以下公式.高度=距离2/8+43.3(距离/4频率)1/2RF传送线射频信号的能量在天线和MODEM之间通过同轴电缆传输。

使用同轴电缆传输射频信号能量,当它沿着电缆传输时,总是要消耗一些信号强度。

消耗的总和与电缆长度成正比例并且假设使用相似的材料与电缆直径成反比信号损失不依赖于在电缆中传输的方向无线电频率信号广泛的传播性反射折射衍射吸收无线电信号在直线线路被传播,象光那样也能够反射、折射和衍射,反射、折射和衍射是在线路里的信号相互作用所产生的自然现象。

反射的发生与无线电信号同样与光一样:信号能在某一类型的物质表面反弹(通常是金属的物质)。

当无线电信号进入一个不同的密度和质量的范围时,反射的速率和方向会发生改变,在两个区域之间,密度有较大的不同时,那么速率与方也存在较大差异。

变换AIRLINK MODEM 的频率在反射区域里通常是没用的。

当无线电信号在边界相进时,通过衍射就能很容易的穿过该区域和区域里的反射障碍(一般是平坦位置的金属建筑)在边界的角落周围形成一条弯曲的信号。

一条无线电信号也弄能够努力的通过障碍物当使用AIRLINK MODEM的无线电信号与树木向遇时这种结果特别明显,AIRLINK MODEM能吸收部分有效的信号能量。

干扰内部带内的相互干扰外界带外的干扰内部带内的相互干扰是无线电频率信号范围占领另一部分无线电信号范围内部的相互干扰不仅出现在工作带宽中而且覆盖在所需的信号里较为准确的名称为内部频道干扰或带内干扰。

外界的相互干扰卷入信号之间那也许在内部有结合或成为重叠的信号。

当那些信号重叠时接收器收到的信号是超负荷的信号。

接收器通常合并线路并选择和整理信号将能够利用的信号留下,将不协调的信号拒绝;因此线路边界和极点的信号能量将会被拒绝。

如此非常强大的信号将会影响和干扰另一信号。

用光谱扫描装置来观察非常强的信号,通过光谱分析来避免外界相互干扰;就可以远离这些频率信号避免相互干扰。

当带外信号形成干扰时在天线馈线中外加一个辅助带通滤波器如此滤波器通常消除带外的干扰,但是不能解决带内干扰的问题。

选择正确的天线方向能避免干扰,用高增益的定向天线是比较实用的,点对点的链路减少天线射线上的干扰从而加强天线接收信号的能量。

改变同一链路上的天线计划方式对于避免干扰是有用的方法。

一个常见的事例是L波段的分页传送器,使用垂直极化总是具有排他性,AIRLINK天线对于水平计划提供最少15DB的抵触信号。

天线定向天线是向同一方向传播无线电能量,每一个类型的定向天线有它的放射线能量的特征,但是他们的方向的程度特征是有区别的。

它的原理就与同乡象一个可条焦距的闪光灯,在那里光线不仅能从点的方向改变,而且也可以调节它的宽度,当它的光线狭窄时,它会聚合光源显得很亮。

这个光线宽度较窄的例子是一个增益的原理,它同样可以应用在天线上,就如同一个闪光灯无线电频率能量的焦点,由天线的位置来决定,因为天线不能够创造能量所以增益的方法是:天线高度的增益、改变天线的发射方向,当选择天线的方向时必须考虑其应用的范围参数的增益和光线的宽度。

全方向天线发射的无线电品绿信号在3600的范围都是相等的,全方向天线的增益可以在3600的方向传播。

高增益全向天线不适合安装在经常倾斜移动的位置(如船)或环境比信号路径高,使所需的信号错过全向天线的放射盘面。

天线的频率和带宽天线总是工作在指定的、邻近的信到和频率,这段频率就叫做一个波段,波段之间的频率范围的宽度就叫做信号的带宽。

例如:从902赫兹到928赫兹有26赫兹频率带宽。

对于商业的目的由厂商提供订约的天线使用的指定波段,天线的带宽通常是由厂商提供固定的说明,厂商使用应用程序使之效果更加完善。

一个天线的带宽宽时,则通常表现会较差,带宽较窄时将会较乐观。

天线带宽只需与社频信号工作频率使用的同宽。

水平和垂直极化方式极化是信号在空间穿过时的方向。

典型的方向是垂直或水平。

信号的极化同无线电波的形状相同。

举个例子,如果天线导向是水平的,那么它就是水平极化信号,对任意给定的两个单元间的链路,规定两者的天线必须是同样的极化方式,如果他们极化方式不同将导致信号丢失。

当两个天线在相同方向上彼此有900的角度,说它们是交叉极化,在这种情况下,发射器发出的信号其中只有极少一部分能量被另一天接收到,当两个天线属于不同的链路(例如一个中心)交叉极化是非常有用的,你可使两个链路间的潜在干扰减小到最小。

环境保护在有保护AIRLINK设备的按装需要遵守工作环境说明。

在AIRLINK与天线之间安装最短距离的电缆。

AIRLINK的可维护性。

大多数AIRLINK设备应安装在室内或具有环境保护的地方。

例外有:在楼外由RUGGED密封罩(环境保护罩)的AIRLINK。

或者是在T1/E1或VF RUGGED上带有环境保护罩的AIRLINK。

安装环境条件必须符合AIRLINK手册或安装指导中给出的操作环境说明。

安装时需要一根最短的从AIRLINK到天线的同轴的电缆。

所安装的AIRLINK(S)应容易维修检修。

闪电闪电危险的分析:1 地理位置2 暴露地点3 涉及的危险什麽是闪电闪电防范 1 主要的 2 次要的闪电危险的分析地理位置暴露地点危险的链路由地理不同引起的闪电,频率变化很大。

例如美国佛罗里达就是闪电活跃区之一。

一个在50米高的塔架上的天线要比它安装在几尺高的低楼房顶上的天线更容易受到闪电的袭击。

电力分配系统的总量决定着;出现在电线危害的瞬间变化的可能性。

如果一个特殊的网路是“危险链路”,那麽对避雷的防范应花费大量的钱。

什麽是闪电闪电是云到云,云到地,地到云的电荷放电。

一次实际的雷击放电会产生一个上千万安培的电流源。

这个脉冲电流是一个典型的上升时间为2μS和书衰退时间是40μS的脉冲。

这个快速上升的脉冲就释放出它的破坏性能量,因为一个很小雷击通过一个很小的电感。

就能产生巨大的电势。

直接的打击是少见的——最大的错误是通过附近的开关或电话线路的松动而引起的。

闪电的防范1主要的防范 2次要的防范主要的防范目的是阻止毁坏性的电流进入你的机器。

次要的防范目的是让破坏性电流离开机器并引如地下可能进入你的系统的方面,包括天线,电话线和AC交流电。

(最重要得防范形式)将应用的各自的潜在的接地。

一个好的接地必须低电阻低电感---因为电击的时间非常快接地系统的好坏依赖于地域的电组成部分组。

通常,多于一个铜金属或金属,钢棒(最小6’,但最好8’)能够组成一个“好的”接地极。

几个短棒之间用扁铁互相焊接起来,具有一个长金属棒更低的阻抗。

接地棒成星形状标注。

并大规格尺寸的电线互相连接。

就能进一步降低在岩和沙土中的阻抗。

大地,设备接地,电话公司与发电长的接地必须合适地互相连接起来以阻止大的电位差出现在他们之间,每个接地都可以通过一根单独的电缆与另一个接地体联在一起,或者采取“闭环”式。

互相连接应采用大金属线(#8AWG)。

既不是双绞也不是标准线,会严重的氧化与腐蚀,并且他们两端的电感变高。

金属相似性:铜从不能损坏钢。

另一个主要得防范是气体管和放电器。

标准TELCO---TYPE气体放电管保护AIRLINK用的双绞线。

AIRLINK T1/E1和输入单元,同AIRLINK PRO T1/E1一样,有内部第二防范被称为TRANSORBS,它以保护单元小的电泳达到主要的防雷电措施。

天线接地铁塔的接地天线连接在铁塔上直流电的接地避雷针同轴脉冲的干扰抑制器因为天线塔是设备最高点,它很可能是闪电进入的路径。

铁塔的接地,天线连接在铁塔上直流电的接地,和避雷针在铁塔上同等重要。

无线电频率信号线从塔上到基地在进入建筑物里以前形成闭环。

一个同轴脉冲的干扰抑制器应装在塔基上或大容量的配电板的接地——不是装备在设备上,馈线应缠绕到发射器方向。

电话线接地不要依赖TELCO闪电的防范主要的防范附加的防范电话线易受到直接打击,和感应到附近的闪电活动一样。

虽然电话公司经常安装一些避雷针,但你不能依赖它解决所有问题。

AIRLINK产品作为一种科技产品它提供主要和次要防范保护。

包括半导体设备,气体放电管,和简单的电感器。

最主要的防范保护是一个三极真空管,它控制不同电压(两个导体之间)同接地电压一样。

当气体电离,它同时提供一个为导体之间的路径。

还有其他形式的保护器,例如金属氧化物变阻体(MOVS),对变压是十分有效的。

但是较慢,因此允许一个变压产生,相对于他们的峰值电压。
