Abstract
【解決手段】 圧力センサ部31は、圧力センサ付き絨毯1の内部に複数行複数列に配置された複数の圧力センサで構成される。この圧力センサ部31は、その表面に加えられる圧力を検知して制御部33に出力する。記憶部32は、初期学習モードにおいて、圧力センサ部31から出力された圧力値を初期値として記憶する。制御部33は、検知動作モードにおいて、圧力センサ部31から出力される圧力値が記憶部32に記憶された初期値よりも所定のしきい値以上大きくなった場合に、異常検知したことを示すデータ信号をモデム部34に出力する。モデム部34は、制御部31から受けたデータ信号を電力搬送波(周波数50〜60Hz)に重畳して電源プラグ2に出力する。
