When the conventional technology of automatic restoration operation using one elevator car was implemented in in a one-shaft multi-car system in which a plurality of elevator cars are operated independently inside the same hoistway, the issue existed that stopping other elevator cars inside the same hoistway was wasteful and also a means was required to retract, etc., other elevator cars so as to not hinder diagnostic operation. In order to solve said issues, the present invention is characterized by comprising: a diagnostic range setting means (14) that sets a diagnostic range for a plurality of elevator cars within the same hoistway so as to encompass the entire area of the hoistway; and an elevator car diagnostic operation control means (15) that independently implements automatic diagnostic operation for each elevator car on the basis of the diagnostic range for each elevator car as determined by the diagnostic range setting means. |
