Monitoring operating condition of automatic elevator door
First Claim
1. An arrangement for monitoring the operational condition of an automatic door of an elevator, in particular of a passenger and/or goods elevator, or of a building, the arrangement comprising:
- an automatic door comprising one or more door leaves that slide in their location horizontally;
a door operator comprising a door motor and a door mechanism for moving the door leaf in its location horizontally;
a closing device for closing the automatic door;
a control system of the door operator for controlling the door motor; and
a device configured to define the operational condition of the closing device and the door mechanism of the automatic door,wherein the device configured to define the operational condition of the closing device and the door mechanism of the automatic door comprises a mechanism configured to determine mechanical energy of the shaft of the door motor of the automatic door during an operating cycle.

12. A method for monitoring the operational condition of an automatic door of an elevator, particularly a passenger and/or goods elevator, or of a building, said method comprising the steps of:
-
determining the operational condition of the automatic door, which comprises one or more door leaves, a door mechanism and/or a closing device; determining state information of the door during an operating cycle; determining mechanical power of the shaft of the door motor during an operating cycle; determining from the mechanical power of the shaft of the door motor mechanical energy of the shaft during an operating cycle; determining, on the basis of the mechanical energy of the shaft of the door motor and the door state information, the magnitude of a friction force and/or the amount of potential energy stored in the door mechanism; and determining the operational condition of the door mechanism and/or the closing device on the basis of the magnitude of the friction force and/or the amount of the potential energy stored in the door mechanism. - View Dependent Claims (13, 14, 15, 16, 17)
