This system, with WIFI technology, could transfer the information of monitoring terminal to ONU equipment, and through optical network, further to the substations. The system could save the core resources, raise the flexibility of monitoring terminal distribution, and ensure the transmission of data to the center of transmission line monitoring system, thus improving the safety of grid opeation. 【Key words】transmission line monitoring system; EPON; WIFI 0 引言 建高速、稳定可靠的输电线路监测系统通信传输平 随着智能电网的建设，对输电线路安全提出了
