Abstract

It is proposed to identify the component parts of a technical facility in an initialization phase and to record specific data of these component parts with the aid of a databank system. In a prognosis phase, the servicing intervals for the component parts of the technical facility are then calculated on the basis of the specific data of these component parts. Optionally, this is then followed by an analysis phase and an optimization phase. This allows the availability, cost-effectiveness and technically up-to-date state of the technical facility to be improved.

Claims

1. A method for maintaining a technical facility, in particular a lighting system, with the aid of a computer system and the following method steps,

in an initialization phase:

identification of the component parts of the technical facility,

recording of specific data of the component parts with the aid of a databank system connected at least periodically to the computer system,

storage of the specific data assigned to the component parts in the computer system,

in a prognosis phase;

calculation of servicing intervals and preparation of servicing plans for the component parts of the technical facility on the basis of the specific data of these component parts.

2. The method as claimed in claim 1, the component parts of the technical facility being connected to the computer system via a bus system and the identification of the component parts taking place via the bus system.

3. The method as claimed in claim 2, the DALI bus system being used as the bus system.

4. The method as claimed in claim 1, the calculation of the servicing intervals being based on estimated operating periods of the component parts of the technical facility.

5. The method as claimed in claim 1, the calculation of the servicing intervals being based on actual operating periods of the component parts determined by the computer system via the bus system.

6. The method as claimed in claim 4, the calculation of the servicing intervals being based on the average service lives or other service life models stored for each component part in the databank system.

7. The method as claimed in claim 1, with an additional

analysis phase,

in which at least one of the following method steps is performed for the component parts of the technical facility:

recording of the respective energy consumption value, stored in the databank system, and storage in the computer system,

calculation of an assessment factor from at least some of the specific data and storage in the computer system,

determination of the frequency of identical or similar component parts and storage in the computer system,

determination of the costs for the component parts of the technical facility and/or energy costs.

8. The method as claimed in claim 1, the prognosis phase comprising one or more of the following additional method steps:

calculation of the replacement requirement for each component part of the technical facility within a preselectable time horizon,

calculation of the time for which each component part will last, measured on the basis of the current stock,

calculation of the procurement and servicing costs,

preparation of an order list for the replacement requirement.

9. The method as claimed in claim 8, with an additional

optimization phase,

which comprises one or more of the following method steps:

reduction of the variety of types of the component parts of the technical facility,

substitution of existing component parts by technologically improved component parts which are updated from a databank, the databank being adjusted and updated online with the data of the manufacturer, in accordance with criteria which can be selected by the user,

optimization of the spare parts store.

10. The method as claimed in claim 9, with an additional

“

what if appraisal”

,

which comprises the following method steps;

calculating

the investment requirement,

the cost-effectiveness, for the existing component parts and for the optimized component parts,

calculating

the saving,

the amortization time, for the optimized component parts.

11. The method as claimed in claim 1, the component parts being lamps and/or associated operational devices.

12. The method as claimed in claim 11, a light control and/or a constant-light control being additionally provided.

13. The method as claimed in claim 1, in which the characteristic economic data, in particular energy and servicing costs, of the facility are calculated as an absolute amount per period of time and per unit area recursively over all the areas of a building in which the facility is installed, and all the rooms located in it, and are reported.

14. A computer program, which performs the method steps as claimed in claim 1 during operation.

15. A data carrier, on which the computer program as claimed in claim 14 is stored.

16. The method as claimed in of claim 5, the calculation of the servicing intervals being based on the average service lives or other service life models stored for each component part in the databank system.

17. The method as claimed in claim 7, the prognosis phase comprising one or more of the following additional method steps:

calculation of the replacement requirement for each component part of the technical facility within a preselectable time horizon,

calculation of the time for which each component part will last, measured on the basis of the current stock,

calculation of the procurement and servicing costs,

preparation of an order list for the replacement requirement.
