PURPOSE: To avoid an erroneous decision in control by increasing/decreasing a load value in a load table in accordance with an input floor and a target floor when allocation assignments are inputted, to prevent a car allocation by a monitoring circuit at the time of an overload. CONSTITUTION: When assignments are inputted from assignment register devices 8 in respective floors, the load tales 13 of all elevators are prepared, and load values are calculated from the number of boarding persons at an inputted floor and the number of alighting persons at a destination floor, to memory the load values as responding costs. The responding costs are compared by comparing devices 11 to allot the assignment to a car 2 having the minimum value. In this case when the load value exceeds the maximum load, a monitoring circuit 14 prevents allocation to the car 2. The load table 13 inputs the signal of a load measuring device 7 via a microcomputer 5 to correct a memorized load value. Thus data needed to the allocation can be correctly gripped, thereby avoiding an erroneous decision in control. |
