Description
(1)ゲートウェイ5は、所定周期Tfで入力される正常信号LSおよび所定周期Tfよりも短い周期Tsで入力される異常信号ISを読み込む信号読込部53と、信号読込部53により読み込まれた異常信号ISの読込回数をカウントするカウント部54と、信号読込部53により読み込まれた異常信号ISが所定の単位時間T1内に含まれる異常状態が、所定時間Twにわたって連続して発生するとき、カウント部54によりカウントされたカウント値mが所定の閾値Q以上であるか否かを判定する判定部57と、を備える(図4)。カウント部54は、信号読込部53により読み込まれる異常信号ISの読込回数の増加に伴い、カウント値mが読込回数よりも増加するように実際のカウント値に対し重み付けする(図5)。
Claims (4)
