Online monitoring technology of transmission line galloping based on RFID acceleration sensor tags

Aiming at that various transmission line galloping wireless monitoring methods have the defects of high power consumption,high cost and not suitable for long-term monitoring. A galloping long-term monitoring is proposed based on radio frequency identification(RFID)acceleration sensor tags,and a RFID acceleration sensor tag structure is designed. For working in passive mode,the design can realize on-line monitoring for a long time. Processing mode of acceleration signal is introduced,trend term removal algorithm based on wavelet transform is proposed. In laboratory environment,the tag communication performance is tested and the simulation experiment of transmission line galloping is carried out. Test results show that the tag has good communication performance;simulation experimental results show that the processed displacement signals reflect galloping of the simulated wire accurately,and the on-line monitoring is realized.
