In view of the difficult patrol inspection and maintenance of condition monitoring system of transmission line in remote mountainous areas,a kind of on-line monitoring scheme for transmission lines in mountainous areas based on LoRa is proposed in this paper. According to the characteristics of LoRa wireless transmission and monitoring environment in the mountainous area,the transmission architecture of mountainous transmission line based on GPRS and LoRa is designed. The multi-objective optimization algorithm is used to optimize the LoRa transmission group in the linear topology of mountainous transmission lines and balance the communication delay and transmission energy consumption of transmission module. The simulation experimental results show that the data transmission success rate of the monitoring system is up to 99%. The proposed proposal,compared with the existing monitoring system of transmission line both at home and abroad,has such advantages as high reliability transmission,low cost and long-term monitoring,and is suitable for transmission line monitoring signals in mountainous areas.
