摘　　要：通信技术是输电线路在线监测数据可靠传输的关键。然而在部分偏远地区,公网通信条件较差,未铺设光纤,专网部署成本过高,通信方式成为输电线路业务发展的主要技术瓶颈。针对这一问题,文章将北斗卫星短报文技术应用在输电线路在线监测系统中,在现场布置一体化通信系统,主站系统采用多指挥机扩展并联方式,并通过增加消息队列和确认重发机制来提高通信的可靠性,实现了状态监测数据的实时回传。文章相关研究很好地解决了偏远地区数据传输问题,实现了输电线路在线监测装置数据的无线接入。Communication technology is the key to transmit online monitoring data of the transmission line reliably. At present, in some remote areas, public communication condition is poor, fiber is not laid, the cost of private network development is too high, and communication is the main technical bottleneck in the development of transmission lines. In this paper, the Beidou satellite short message communication technology is applied into the online monitoring system of transmission lines, integrated communication system is deployed on site. The method of extending parallel connection of multi command machines is used in the master station system. Message queue and confirm-retransmission are used to improve the reliability of communication, which realized the real-time feedback of monitoring data. The method can solve the problem of data transmission in remote areas, and realize the wireless access of the device data in transmission line on line monitoring.
