Design of Wireless Sensor Network for Transmission Line Condition Monitoring based on 6LoWPAN

Through effective condition monitoring, remote monitoring of transmission lines can be realized, and the efficiency of transmission line inspection can be greatly improved. Wireless communication technology is one of the core technologies of transmission line condition monitoring. At present, the standardization of various wireless communication technologies is not yet completed, and the interconnection between different manufacturers cannot be realized, which restricts the application effect of various monitoring devices. In this paper, data characteristics and transmission characteristics of various sensors are summarized for online monitoring of transmission lines. 6lowpan adaptation is carried out based on IEEE802.15.4 wireless communication protocol stack to realize time synchronization characteristics. Meanwhile, the protocol stack optimization and code coding are further considered for data burst reporting. Finally, based on the ARM M4 MCU and the RF chip supporting 433MHz band, the wireless communication module design and protocol stack transplantation are completed, supporting the long-distance and standardized wireless transmission of all kinds of data in the transmission line monitoring scenario.
