Zusammenfassung: | The present invention relates to a wireless signal harvesting method and a system for same, which: collect wireless signals of multiple frequency bands, which are present in life surroundings, according to each band by means of multiple antennas; convert the wireless signals to DC voltages, which are then aggregated; thereby use the aggregated DC voltages as power for a mobile device and a small IoT sensor; and, as a result, can increase power operation time and reduce the replacement cycle of a battery.
La présente invention concerne un procédé de collecte de signal radio et son système, qui : collectent des signaux radio de multiples bandes de fréquence, qui sont présents dans l'environnement de vie, selon chaque bande au moyen de multiples antennes ; convertissent les signaux radio en tensions continues, qui sont ensuite agrégées ; utilisent ainsi les tensions continues agrégées en tant qu'alimentation d'un dispositif mobile et d'un petit capteur d'IdO ; et, en conséquence, peuvent augmenter le temps de fonctionnement de puissance et réduire le cycle de remplacement d'une batterie.
본 발명은 무선 신호 하베스팅 방법 및 이를 위한 시스템에 관한 것으로서, 생활 주변에 존재하는 복수의 주파수 대역의 무선신호를 복수의 안테나를 이용하여, 각 대역 별로 수집하여 직류 전압으로 변환 후, 합산함으로써, 모바일 기기 및 소형 IoT 센서의 전원으로 사용함에 따라 전원 동작 시간을 기존보다 증가시킬 수 있고, 배터리 교체 주기를 감소시킬 수 있다. |
