Disclosed is a method for measuring opening and closing delay time of elevator brake, the method including outputting, by a brake signal output unit, a brake signal, receiving, by a brake signal checking unit, 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, 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, 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, the drive determination signal and the counted value to compute a brake opening/closing delay time. |

1. A method for measuring opening and closing delay time of elevator brake, the method comprising:
outputting, by a brake signal output unit, a brake signal; receiving, by a brake signal checking unit, 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, 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, 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, the drive determination signal and the counted value to compute a brake opening/closing delay time. |
