摘要
馈线自动化系统采用有线中继通信方式时,为了远距离传输信息,中继点的线路收发器要对信息进行中继放大,并且当某个中继点发生故障或维修时仍能保证线路的正常通信,还要解调分站对智能终端FTU的“巡测”或“故障查询”信号,调制“节点终端的自报”等信息。文中研究了具有上述功能的线路收发器的电路组成和工作原理。
To transmit information in long distance, while feeder automation system working in wire communication mode, the line transceiver of relay node should amplify the in- formation. The transceiver should still keep the line working well even if one of a relay node has some trouble. Meanwhile it should demodulate the tour gauging signal or the trouble detected signal from substations to FUT, and should modulate the FTU＇s signal etc. The hardware configuration and the principle of the transceiver with the functions above is introduced.
