Claims (4)
- 被締結物を締結し締結後の自身の緩みを検出するためのセンサ付き締結具であって、
3軸加速度センサおよび3軸磁気センサを含む姿勢検出センサと、前記姿勢検出センサの検出情報を無線出力する送信部とを備えるセンサ付き締結具。 - 前記姿勢検出センサは、前記検出情報を定期的に出力する請求項1に記載のセンサ付き締結具。
- 請求項1または2に記載のセンサ付き締結具と、前記センサ付き締結具から無線出力された前記検出情報を受信する監視装置とを備える緩み検出システムであって、
前記監視装置は、前記検出情報に基づき前記センサ付き締結具の姿勢情報を演算し、前記姿勢情報の時系列変化から前記センサ付き締結具の緩みの有無を判定する緩み検出システム。 - 前記センサ付き締結具は、一の被締結物に対して複数使用されており、
前記監視装置は、前記姿勢情報の時系列変化を、複数の前記センサ付き締結具の間で比較することにより、緩みが生じた前記センサ付き締結具を判別する請求項3に記載の緩み検出システム。
