Abstract

A method and device for maintenance of an elevator installation or an escalator installation communicates the presence of a maintenance technician at the elevator or escalator installation to a remote service center. The service center is thus informed about that the maintenance technician has to maintain or is maintaining or has maintained a specific installation and is in a position of checking the quality of this maintenance. The maintenance operations are recorded as a maintenance record and communicated to the service center. For example, the maintenance record contains details about which maintenance technician on which day of the year and for how long has undertaken which maintenance operations on a specific elevator or escalator installation. The quality of a thus detected maintenance can then be compared with a quality standard. In addition, the maintenance operations performed are thus uniquely detected and can be evaluated.

Claims

1. A method for maintenance of an elevator installation or an escalator installation, comprising the steps of:

a. communicating a presence of at least one maintenance technician at the elevator installation or the escalator installation to a remote service center; and

b. recording maintenance operations carried out by the at least one maintenance technician at the elevator installation or the escalator installation as a maintenance record.

2. The method according to claim 1 including identifying the at least one maintenance technician at the elevator installation or the escalator installation.

3. The method according to claim 2 wherein the at least one maintenance technician is identified by recognition of at least one of at least one identification code, at least one admittance feature, and positional localization in a network at the elevator installation or escalator installation.

4. The method according to claim 1 including communicating the maintenance record to the service center.

5. The method according to claim 1 including checking serviceability of the elevator installation or the escalator installation by the service center after conclusion of the maintenance operations.

6. The method according to claim 1 communicating the maintenance record by the service center a customer associated with the elevator installation or the escalator installation.

7. The method according to claim 1 including ascertaining a maintenance requirement by the elevator installation or the escalator installation and reporting the maintenance requirement to the service center or to the at least one maintenance technician.

8. The method according to claim 1 including communicating state data of the elevator installation or the escalator installation to the service center, based on this state data determining a maintenance requirement by the service center and reporting the maintenance requirement to the at least one maintenance technician.

9. The method according to claim 1 including determining a maintenance state by the elevator installation or the escalator installation and displaying the maintenance state.

10. A service center for performing the method according to claim 1.

11. A device for identification of at least one maintenance technician, comprising:

a recognition unit arranged at an access of an elevator installation or an escalator installation for recognition of at least one identification code of a maintenance technician or at least one admittance feature of the maintenance technician, the recognition unit is arranged for positional localization of the maintenance technician in a network at the elevator installation or the escalator installation;

said recognition device including means for creating a maintenance record of the maintenance operations at the elevator installation or the escalator installation; and

said recognition device including means for communicating the maintenance record to a remote service center by way of a telephone network.

12. The device according to claim 11 wherein a presence of the identified maintenance technician is communicated to the remote service center by said recognition device over the telephone network.

13. The device according to claim 11 wherein said recognition device communicates a recognized identification code or a recognized admittance feature or a positional localization of the maintenance technician to the remote service center by way of the telephone network.
