ABNORMALITY DETECTION MEANS, ABNORMALITY DETECTION METHOD AND ABNORMALITY DETECTION PROGRAM
To provide abnormality detecting means, an abnormality detection method and an abnormality detection program capable of detecting abnormality of a dimmer.SOLUTION: The abnormality detection means includes: abnormality determination means which determines whether current between transparent electrodes in a determination target period is equal to or larger than an overcurrent determination threshold, and also determines that detection of current equal to or more the overcurrent determination threshold is abnormal; and a timing control circuit in which a predetermined period until a spike of current between transparent electrodes generated at an application timing of a voltage pulse becomes less than the overcurrent determination threshold is a non-target period, and a period of time when the non-target period elapses from a timing of application of a voltage pulse is set as a start timing of the determination target period.SELECTED DRAWING: Figure 1
【課題】調光装置の異常を検出可能にした異常検出手段、異常検出方法、および、異常検出プログラムを提供する。【解決手段】異常検出手段は、判定対象期間における透明電極間の電流が過電流判定用閾値以上であるか否かを判定し、過電流判定用閾値以上の電流が検出されることを異常であると判定する異常判定手段と、電圧パルスの印加タイミングに生じた透明電極間の電流のスパイクが過電流判定用閾値未満になるまでの所定期間が非対象期間であり、電圧パルスの印加タイミングから非対象期間が経過したときを判定対象期間の開始タイミングとするタイミング制御回路と、を備える。【選択図】図１
