OVERLOAD DETECTION SYSTEM
PROBLEM TO BE SOLVED: To provide an overload detection system that enhances convenience for a user of a shutter device.SOLUTION: An overload detection system includes: an acquisition section 84a for acquiring a number of rotation of a driving section of an opening/closing unit for each section of movement, each time a shutter curtain is moved for opening/closing; an overload standard value setting section 84b for setting an overload standard value for each section of movement, each time the shutter curtain is moved for opening/closing; a determination standard value setting section 84c for setting a determination standard value for each section of movement, each time the shutter curtain is moved for opening/closing; and a first determination section 84d for determining whether the number of rotation of the driving section acquired by the acquisition section 84a indicates a load smaller than the determination standard value for each section of movement, each time the shutter curtain is moved for opening/closing. The overload standard value setting section 84b performs a third detection sensitivity reduction process when setting the overload standard value for the determination in a consequent movement for opening/closing, in a case when there is a section of movement of which the load has been determined as being smaller than the determination standard value by the first determination section 84d in a last movement for opening/closing.SELECTED DRAWING: Figure 2
【課題】シャッター装置の使用におけるユーザの利便性を向上させることが可能になる、過負荷検知システムを提供すること。【解決手段】過負荷検知システムは、シャッターカーテンの開閉移動毎に、開閉機の駆動部の回転数を移動区間毎に取得する取得部８４ａと、開閉移動毎に、過負荷基準値を移動区間毎に設定する過負荷基準値設定部８４ｂと、開閉移動毎に、判定基準値を移動区間毎に設定する判定基準値設定部８４ｃと、開閉移動毎に、取得部８４ａにて取得された駆動部の回転数が判定基準値よりも低い負荷量であるか否かを移動区間毎に判定する第１判定部８４ｄとを備え、過負荷基準値設定部８４ｂは、次順の開閉移動における判定のための過負荷基準値を設定する際に、直近の開閉移動において第１判定部８４ｄにて判定基準値よりも低い負荷量であると判定された移動区間が存在する場合には、第３検知感度低下処理を行う。【選択図】図２
