The invention provides a door opening and closing detection system of an elevator, which improves the detection precision of door opening and closing of the elevator. A door opening/closing detection system is provided with a magnetic sensor provided in an elevator car, and an opening/closing detection device for detecting the opening/closing of a metal landing door on the basis of whether or not the difference between values measured by the magnetic sensor in a time interval exceeds a threshold value. A magnet is provided in the landing door or in the vicinity of the landing door.

    本发明提供一种电梯的门开闭检测系统,其提高电梯的门开闭的检测精度。门开闭检测系统具备设置在电梯的轿厢的磁传感器以及基于磁传感器在时间区间的测量值的差值是否超过阈值来检测金属制的层站门的开闭的开闭检测装置,在层站门或者层站门的附近具备磁铁。
