PURPOSE:To renew each time band according to the variation of the traffic quantity and assort the old statistical information to the newly set time band by installing a statistical processing means for the traffic quantity, time band division judging means, and a statistical quantity renewal means. CONSTITUTION:A statistical processing means 7 for traffic quantity divides a day into a plurality of time bands consisting of the prescribed time width (5min.), and the statistical processing of the traffic quantity of an elevator in each time band is carried out for a prescribed period (one hour), and the statistical information is memorized in a statistical memory 9. A control information preparing means 8 prepares the control information for each divided time on the basis of the memorized statistical information, and sends the statistical information into an operation control device 3. After the statistical processing for a prescribed period (one week), a time band dividing judging means 6 renews the dividing time for each above-described time band to a time band consisting of the new divided time. The statistical quantity renewal means 7 calculates the length of the time band in which the new time band is superposed with the old time band, and the traffic statistical quantity in the new time band is calculated on the basis of the statistical quantity of the traffic quantity in the old time band which is superposed with the length of the time band. |
