Low Delay Technology Research of Transmission Line Tower Monitoring Network Integrating WSN and RFID

The tower is a key component of the transmission line system and its stability and reliability is the guarantee for the operation safety of the entire transmission line. This paper proposes a transmission line tower monitoring network integrating wireless sensor network (WSN) and radio frequency identification (RFID). Compared to current designs, the proposed monitoring network shows the advantages of low cost, fast fault locating and long-time monitoring. The relay node setting is the key to the research of monitoring network performance. Therefore, this paper establishes the transmission delay and cost model of relay nodes of the monitoring network to obtain the balance of delay performance and cost under different conditions. For the redundant data of RFID, this paper presents a data cleaning algorithm for the transmission line tower monitoring, which can effectively reduce the redundant data collected from the reader end. This algorithm holds the advantages of simple and high real-time.
