[0057] 光纤线路终端作为光纤传输网络的节点,其主要作用是:在下行链路中,将光纤传输网中的采用IEEE802.5令牌环(Token Ring)协议传输的载有传感器节点和簇头节点配置信息的光信号传输至远端天线单元。 [0057] The optical fiber transmission line terminal as a node of the network, its main role is: in a downlink, the optical transmission network using carrier transmission protocol IEEE802.5 Token Ring (Token Ring), and a sensor cluster nodes first optical signal transmitting node configuration information to the remote antenna unit. 在上行链路中,将远端天线单元收集的来自各个簇头节点和节点的大数据量信息按照IEEE802.5Token Ring协议标准经过光纤传输网发送至中央控制单元。 In the uplink, the large amount of data from each cluster head node, and transmitting the collected remote antenna unit to the central control unit in accordance with IEEE802.5Token Ring protocol standard through an optical fiber transmission network.

[0059] 其中,中央控制单元至远端天线单元的下行传输的具体传输方式优选为,中央控制单元采用单边带(Single Side Band,简称SSB)或者载波抑制(Optical CarrierSuppress1n,简称OCS)方式产生60GHz光纤无线电(Rad1-over-Fibe,简称RoF)信号,RoF信号经光纤线路终端传输至远端天线单元,远端天线单元将RoF信号直接通过光电耦合转变为60GHz毫米波,并将毫米波向传感器节点发射,这样就而无需60GHz本地振荡器。 [0059] wherein the central control unit to the remote antenna unit for downlink transmission of a specific transmission mode preferably, the central control unit using single sideband (Single Side Band, referred to as SSB) or carrier suppression (Optical CarrierSuppress1n, referred to as OCS) mode generated 60GHz radio over fiber (Rad1-over-Fibe, referred RoF) signals, RoF signal transmission line terminal through the optical fiber to the remote antenna unit, the remote antenna unit RoF signals directly converted by the photocoupler is 60GHz millimeter wave, millimeter wave and to transmitting sensor node, so that the local oscillator without 60GHz.

[0060] 或者,也可以采用基带数字信号传输。 [0060] Alternatively, the transmission digital baseband signal may be used. 由中央控制单元所发出的基带数据信号通过电光调制器完成电光变换,再由光载波传送到指定的远端天线单元。 Baseband data signal emitted by the central control unit is completed by the electro-optic modulator the electro-optical conversion, and then transmitted to the optical carrier by the remote antenna unit designated. 光信号在远端天线单元利用光电耦合器件变换成基带信号,再由60GHz本地振荡器变频到毫米波进行发射。 In the optical signal using the remote antenna units photocoupler device into a baseband signal, and then the 60GHz frequency conversion to the millimeter wave local oscillator for transmission.

[0061] 在上行信息采集链路中,远端天线单元的主要功能是利用60GHz毫米波接收机将来自簇头节点或传感器节点的毫米波信号下变频至基带,之后利用激光器和马赫任德调变器(Mach-Zenhder Modulator)调制成光信号,经光纤传输网传输至光纤线路终端。 [0061] In the uplink information acquisition chain, the main function of the remote antenna unit using a millimeter-wave receiver 60GHz millimeter wave signal from the sensor node or cluster-head node to baseband, with a laser and then de Mach any adjustment variable device (Mach-Zenhder modulator) into a modulated optical signal to an optical fiber transmission line terminal through the optical fiber transmission network.
