ELEVATOR SYSTEM AND ELEVATOR NON-CONTACT BUTTON OPERATION DETECTION METHOD

To prevent false detection when a non-contact button is installed in an elevator.SOLUTION: An elevator system includes a non-contact operation detection unit 211 detecting the operation of a button based on a light receiving amount of a light receiving window arranged in the button, and a correction unit 213 detecting an offset value of the light receiving amount detected by the non-contact operation detection unit 211 and subtracting the detected offset value from a detection signal of the light receiving amount to obtain a differential value. The non-contact operation detection unit 211 detects the non-contact operation from the differential value obtained from the correction unit 213. Accordingly, the non-contact operation detection unit 211 is prevented from erroneously detecting that there is the non-contact operation due to contamination of the light receiving window, incidence of disturbance light, and the like while a finger of an elevator user and the like is not close to the non-contact button.SELECTED DRAWING: Figure 1 【課題】エレベーターに非接触ボタンを設置した場合の誤検出がないようにする。【解決手段】ボタンに配置された受光窓の受光量から、ボタンの操作を検出する非接触操作検出部２１１と、非接触操作検出部２１１が検出した受光量のオフセット値を検出し、検出したオフセット値を受光量の検出信号から減算して差分値を得る補正部２１３とを備える。そして、非接触操作検出部２１１は、補正部２１３で得た差分値から非接触操作を検出する。これにより、非接触操作検出部２１１が、受光窓の汚れや外乱光の入射などにより、エレベーター利用者の指などが近接していない状態で、誤って非接触操作ありと検出することを防ぐ。【選択図】図１
