摘　　要：根据怀化市区域电网１１０ ｋＶ 枢纽变电站通信机房无人值守的实际情况，通过对ＰＣＭ 基群帧结构进行分析，提出利用帧结构中信令ｂ 码传输载波机收导频状态信号，在调度端采用信令转换及告警显示电路，实现对远端载波机工作状态的远方监测。According to the Huaihua elec.power network is not on duty for carrier wave centre station,the PCM basis-group's frame structure is analysed.In this paper, using message B code's transmission carrier wave which received from guide frequency signal and the realization of monitoring the work state for distant place carrier wave of guide-frequency are pointed out.
