CONTROL SYSTEM OF ELEVATOR

To provide a control system of an elevator provided with a plurality of cages in which the system prevents wasteful operation of the cages even when a user does not notice that assignment of a landing call has changed.SOLUTION: There is provided a control system of an elevator in which a control device can change an assignment destination of a landing call from a first cage to which the landing call is assigned to a second cage, and when the assignment destination is changed, any one of other cages excluding those which correspond to predetermined conditions is selected as the second cage. The predetermined conditions mean conditions in which when a departure floor and a destination floor of the landing call assigned to the first cage are designated as a departure floor which is subject to change and a destination floor which is subject to change, respectively, the departure floor which is the same as the departure floor which is subject to change and the destination floor which differs from the destination floor which is subject to change among the destination floors located in the same direction as the destination floor which is subject to change when seen from the departure floor are already assigned as the landing call.SELECTED DRAWING: Figure 3 【課題】複数の乗りかごが設けられたエレベータにおいて、乗場呼びが割当変更されたことに利用者が気付かなかった場合でも、乗りかごに無駄な動作が発生することを防止する。【解決手段】エレベータの制御システムにおいて、制御装置は、乗場呼びの割当先を、当該乗場呼びが割り当てられている第１の乗りかごから第２の乗りかごへ変更することが可能であり、当該割当先の変更を行う場合には、第２の乗りかごとして、所定条件に該当する乗りかごを除いた他の乗りかごの何れか１つを選択する。ここで、所定条件は、第１の乗りかごに割り当てられている乗場呼びの出発階及び行先階をそれぞれ変更対象出発階及び変更対象行先階とした場合に、変更対象出発階と同じ出発階と、当該出発階から見た場合に変更対象行先階と同方向に位置する行先階のうちの当該変更対象行先階とは異なる行先階と、が乗場呼びとして既に割り当てられているという条件である。【選択図】図３
