振動発電技術を用いたケーブル張力モニタリングシステムの開発

抄録

This study develops a cable tension monitoring system that uses vibration power generation technology. The system uses vibration power generation technology to generate electricity from the vibration of cables caused by vehicle movement on an actual extradosed bridge. The power is used to transmit tension data calculated from the vibration frequency. The analytical model was used to determine which cables should be tuned to which dominant vibration frequencies. In addition, measurements of the cables were conducted on the bridge to investigate the amount of power generated by the vibration. It was found that LoRa communication is possible by tuning to the dominant vibration frequency of the cable, which vibrates strongly when a truck is moving.
