ず、エレベータの復旧作業に手間どることがあった。In the conventional remote monitoring system, the failure report, which is issued when an abnormal operation occurs in the elevator, indicates that there is some failure content such as an abnormal start of the elevator or an abnormal safety system of the elevator. However, it is not possible to obtain specific situation data for the elevator failure. In particular, when a failure is automatically restored and the elevator is restarted, a restoration technician dispatched to the site will listen to detailed failure conditions such as the location of the failure and the state of the door from the passengers of the failed elevator. However, it is necessary for the recovery work. For this reason, when there is no passenger in the elevator at the time of failure, or when the elevator fails in an unmanned state, the failure situation may not be sufficiently grasped, and it may take time to restore the elevator.

However, the operation management apparatus according to the disclosure creates an operation map of the elevator as needed for operation management of the elevator, and does not necessarily obtain an operation map of the elevator at the time of failure. The present invention has been made in view of the current state of failure recovery of an elevator as described above, and an object of the present invention is to provide, when an elevator failure occurs, operation data of the elevator immediately before the occurrence of the failure, which enables the operator to grasp the failure status of the elevator remotely. It is to provide a remote failure diagnosis device for an elevator displayed in.
