Zusammenfassung:The present invention relates to a wireless communication system for a seat belt. The wireless communication system comprises: a detection unit provided on each seat to detect whether a seat belt is fastened; a sub-control unit provided on each seat to transmit a fastening signal by the detection unit regarding whether the seat belt is fastened through wireless communication; and a main control unit provided in a vehicle, wirelessly communicating with each sub-control unit, waking up the sub-control unit through wireless communication, receiving the fastening signal from the sub-control unit after the sub-control unit wakes up, to determine whether the seat belt for each seat is fastened, and determining that the sub-control unit breaks down when the fastening signal is not received from the sub-control unit after the sub-control unit wakes up. Therefore, various seat functions can be implemented. 본 발명은 시트벨트 무선통신 시스템에 관한 것으로, 각각의 시트에 마련되며 시트벨트의 체결 여부를 감지하는 감지부; 각각의 시트에 마련되며, 감지부의 시트벨트 체결 여부에 관한 체결여부신호를 무선통신으로 송신하는 서브제어부; 및 차량에 마련되며, 각각의 서브제어부와 무선통신을 수행하고, 무선통신을 통해 서브제어부를 웨이크업 하며, 서브제어부의 웨이크업 이후 서브제어부로부터 체결여부신호를 수신하여 각 시트의 벨트 체결여부를 판단하고, 서브제어부의 웨이크업 이후 서브제어부로부터 체결여부신호를 수신하지 못할 경우 해당 서브제어부를 고장으로 판단하는 메인제어부;를 포함하는 시트벨트 무선통신 시스템이 소개된다.
