Method of highly efficiently operating elevator by analyzing operation of elevator

A method of highly efficiently operating an elevator by analyzing an operation of the elevator, the method comprising:

• a base information collecting step S10 of measuring and collecting information on a change over time in magnitudes of current values of a driving unit when the driving unit for moving the elevator upward or downward moves the elevator upward in a normal state, measuring and collecting information on a change over time in magnitudes of current values of the driving unit when moving the elevator downward, classifying the measured information into driving information of the driving unit when moving the elevator upward and driving information of the driving unit when moving the elevator downward, and storing the driving information of the driving unit when moving the elevator upward and the driving information of the driving unit when moving the elevator downward as base information of the driving unit;
• an operating information storing step S20 of measuring in real time the driving information of the driving unit when the driving unit operates, analyzing the measured information based on the base information of the driving unit which is collected in the base information collecting step S10, and extracting and storing a result of the analyzing of the measured information as the operating information of the elevator;
• and
• an operation control step S30 of analyzing and digitizing the operating information of the elevator which is stored for a long period of time in the operating information storing step S20, and controlling door closing time of the elevator for respective floors based on the digitized information.
