PROBLEM TO BE SOLVED: To provide a brake switch system for an elevator which can diagnose a brake switch with measurement accuracy required for management of tendency of secular changes, and can also be carried in a diagnostic site.SOLUTION: A brake switch diagnosis system for an elevator comprises a measurement device 10 having a calculation part 22 to calculate the following distances based on a release image, a suction image, an image under suction operation, and an image under release operation, of a brake core 1 photographed by a camera part 7 in a condition in which stroboscopic light is emitted by a stroboscopic light-emitting part 6: a distance L1 corresponding to a position during suction which is an operation position of a brake switch 5 under suction operation of the brake core 1; a distance L2 corresponding to a brake stroke which is a stroke to reach a suction condition from a release condition of the brake core 1; and a distance L3 corresponding to a position during release which is an operation position of the brake switch 5 under release operation of the brake core 1.SELECTED DRAWING: Figure 1

    【課題】経年変化の傾向管理に必要とされる測定精度でブレーキスイッチの診断を行うことができ、しかも診断現場への持ち運びを可能にする。【解決手段】本発明に係るエレベーターのブレーキスイッチ診断システムは、ストロボ発光部6でストロボ発光させた状態においてカメラ部7で撮影したブレーキコア1の釈放画像、吸引画像、吸引動作中の画像、及び釈放動作中の画像に基づいて、ブレーキコア1の吸引動作中のブレーキスイッチ5の作動位置である吸引時位置に相当する距離L1と、ブレーキコア1の釈放状態から吸引状態に至るまでのストロークであるブレーキストロークに相当する距離L2と、ブレーキコア1の釈放動作中のブレーキスイッチ5の作動位置である釈放時位置に相当する距離L3とを計算する計算部22を有する計測装置10を備えている。【選択図】図1
