PROBLEM TO BE SOLVED: To provide an elevator group management controller capable of continuing group management control with a normal machine excluding an abnormal machine by separating the abnormal machine from group management control running when the abnormal machine is discovered. SOLUTION: A data length transmitted from each machine is measured by a data length measuring means 8 and, when the data length exceeds a predetermined abnormality determination value, an abnormal machine determining means 9 determines that the machine transmitting the data is abnormal, and cuts off this abnormal machine physically from a transmission path 6 (6a, 6b and 6c) by a transmission switch 7. Thus, group management control is continued only by other normal machines. Thus, only the abnormal machine is set to backup running, and the group management control is continued for the other normal machines. |
