<P>PROBLEM TO BE SOLVED: To avoid a situation that a stop of a car at a position largely away from a landing zone causes difficulties in rescuing passengers. <P>SOLUTION: This method includes a platform door opening/closing detector 11, a platform door opening/closing detector 12, a speed detection means 14, a position detection means 13, a memory where time series variation amount reference data on a car speed and a car position are memorized beforehand when emergency shutdown control is performed under a door opening state, and a car deceleration comparison determination section 104 that creates time series variation amount data on the car speed and the car position from a point when a door opening state is detected to be collated with the time series variation amount reference data, and detects a deceleration abnormality if the car speed or the car position deviates by a predetermined amount or larger from the reference data when an elevator state is estimated on the basis of respective detection results and a car under a door open state while traveling is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
