Abstract

The invention relates to a system and a method for the condition-based maintenance of at least one decentralised technical installation. The system comprises recording means for recording condition values of the technical installation and transmission means for transmitting the recorded condition values to a central maintenance management system, which comprises first means for evaluating the condition values and second means for generating maintenance orders, depending on the result of the evaluation of the condition values. Said condition-based maintenance is operated, in particular when a global maintenance management system is used, by the transmission of condition values from an automation system via e-mail or HTTP transfer.

Claims

1. A system for condition-based maintenance of at least one decentralized technical installation, the system comprising:

a mechanism for recording condition values of the technical installation; and

a mechanism for transmitting the recorded condition values to a central maintenance management system, the central maintenance management system comprising a first mechanism for evaluation of the condition values and a second mechanism for generating maintenance orders according to the result of the evaluation of the condition values, wherein the mechanism for transmitting the recorded condition values is adapted for transmitting the recorded condition values to the central maintenance management system using e-mail.

2. The system in accordance with claim 1, wherein the second mechanism of the central maintenance management system generates the maintenance orders according to predefined rules.

3. The system in accordance with claim 2, wherein the central maintenance management system comprises a third mechanism for implementation, monitoring and/or documentation of the generated maintenance order.

4. The system in accordance with claim 2, wherein the mechanism for transmitting is using a http protocol.

5. The system in accordance with claim 2, wherein the mechanism for recording is integrated into a logical program controller or a SCADA system.

6. The system in accordance with claim 2, wherein the maintenance management system is connected to an industrial framework system.

7. The system in accordance with claim 1, wherein the central maintenance management system comprises a third mechanism for implementation, monitoring and/or documentation of the generated maintenance order.

8. The system in accordance with claim 7, wherein the mechanism for transmitting is provided for the transmission of the recorded condition values by means of http transfer.

9. The system in accordance with claim 7, wherein the mechanism for recording is part of a stored program controller or a SCADA system.

10. The system in accordance with claim 7, wherein the maintenance management system is linked to an industrial framework system.

11. The system in accordance with claim 1, wherein the mechanism for transmitting is adapted for using a http transfer.

12. The system in accordance with claim 11, wherein the mechanism for recording is part of a stored program controller or a SCADA system.

13. The system in accordance with claim 11, wherein the maintenance management system is connected to an industrial framework system.

14. The system in accordance with claim 1, wherein the mechanism for recording is part of a stored program controller or a SCADA system.

15. The system in accordance with claim 14, wherein the maintenance management system is connected to an industrial framework system.

16. The system in accordance with claim 1, wherein the maintenance management system is connected to an industrial framework system.

17. A method for condition-based maintenance of at least one decentralized technical installation, comprising:

recording condition values of the technical installation by a recording mechanism;

transmitting by a transmission mechanism using email the recorded condition values to a central maintenance management system for automated evaluation;

evaluating the condition values by the central maintenance management system; and

creating maintenance orders by the central maintenance management system relative to the result of the evaluation of the condition values.

18. The method in accordance with claim 17, wherein the maintenance management system uses a first mechanism for evaluating the condition values and a second mechanism for creating the maintenance orders.
