Apparatus for estimating traffic condition value of elevators

Abstract From the Canadian patent

An apparatus for estimating the traffic condition value of elevators wherein the period of time of elevator operation is divided into a plurality of sections the, traffic condition value concerning the elevators is measured for each of the sections, and the traffic condition value of the corresponding section is estimated from the measured value; comprising comparison means to compare the measured value and the estimated value already calculated and, weighting means to weight the measured value on the basis of a result of the comparison, the traffic condition value being estimated anew from the weighted measured value. Thus the estimative value can be prevented from greatly differing from …
