馈线自动化系统采用有线中继通信方式，实现分站和各个FTU 的通信，分站和分站之间的通信，分站和主站之间的通信。用四频复用FSK 数字调制体制，通过对四个副载波的合理调配，在一条线路上实现多路、多种类型的通信。文中着重分析了通信网中信息传输的基本原理，线路收发器中信息的调制与解调的过程和实现方法。

Abstract： The feeder automation (FA) system is based on relayed wire communication in order to achieve communication between substation and every FTU, and each substation, and the main station. Using four-frequency reuse FSK digital modulation technology and properly adjusting the four carrier waves, this paper describes how to realize multi-route and multi-kinds signals transmit within a communication line in the feeder automation system. It emphasized on the transmission principle of the information in the communication net, and emphasized on the realization method how to modulate and demodulate in the line transceiver.
