摘要：

目前输电线路监测系统大多采用2G/3G无线公网进行通信，但大山深处2G/3G信号较弱或无信号，使得通信时断时续或直接中断，导致采集到的状态监测数据难以可靠地传输到主站，或者当有高清视频需求时，2G/3G无法满足这种高带宽要求。针对该问题，提出2G/3G+5.8 GHz或OPGW+5.8 GHz融合通信模式，将信号自动切换到5.8 GHz通信模式，在主干线路与光纤复合架空地线（OPGW）融合后传回主站。在光纤融合通信基础上设计了输电线路监测系统及工作流程，最后给出了应用实例和未来发展前景。

Abstract:

When in the depths of the mountains,2G/3G signal is weak or don't exist,or when the high definition video is needed,2G/3G couldn't meet requirements of such high bandwidth,so that communication is intermittent or interrupt,resulting in the condition monitoring data is difficult to transmit reliably to the master station.To solve this problem,2G/3G+5.8 GHz or 5.8 GHz +OPGW converged communication mode was proposed,the signal could be switched automatically to the 5.8 GHz communication mode,and transmits back to the master station after converging the main line and OPGW.Based on the optical fiber converged communication,the transmission line monitoring system and work flow were designed and the application example and the future development prospect were given finally.

Key words: transmission line monitoring, 2G/3G communication, 5.8 GHz communication, OPGW, converged communication, switching process
