PURPOSE:To carry out the allotment process of elevator units by making the first transmission route effective in a normal condition, and the third transmission route effective when the abnormal condition of a cages control device is detected. CONSTITUTION:The entrance data is transmitted from an entrance control device 6 to a group management control device 10 through the first transmission route 11 and a cages control device 3 in a normal condition. And when the cages control device 3 is abnormal, an abnormality detecting means outputs a change-over signal E and a change-over circuit 33 is converted to a contact (b) side. As a result, the entrance data is transmitted directly to the group management control device 10 from the entrance control device 6 through the third transmission route 30. Consequently, the entrance data transmission control is carried out by the group management control device 10, and even though the cages control device 3 is down, an entrance data of another system is picked up to the group management control device 10 and made effective. Consequently, an operational allotment process of elevator units can be carried out. |
