Disclosed is a method for measuring opening and closing delay time of elevator brake, the method including: outputting, by a brake signal output unit (20), a brake signal; receiving, by a brake signal checking unit (30), the brake signal and determining whether the brake signal is an opening signal or a closing signal to output an opening/closing determination signal; receiving, by a brake counter unit (40), the opening/closing determination signal, and starting a count for measuring a brake opening time or a brake closing time to accumulate and output counted value; determining, by a motor drive checking unit (50), whether a motor configured to drive an elevator is driven upon receipt of the counted values and outputting a drive determination signal; and receiving, by a brake opening/closing delay computation unit (60), the drive determination signal and the counted value to compute a brake opening/closing delay time. |
