Abstract

The invention relates to a central data collection apparatus. The central data collection apparatus comprises an interface for receiving data relating to devices arranged at a plurality of different installation sites. A data storage stores the data received via the interface. A data distributor is configured to receive a request for data regarding a specific device identified in the request from a user equipment, to access the user credential storage for determining the access rights of the, to determine what, parts of the data regarding the identified device the user is authorized to receive and to allow the user equipment to access the part of the data the user is authorized to access.

First claim

The invention claimed is:

1. A central data collection apparatus, the central data collection apparatus comprises:
an interface for receiving data relating to devices and which data is provided by control devices arranged at a plurality of different installation sites for monitoring the operation of the respective devices at the respective installation sites,
a data storage for storing the data received via the interface,
a user credential storage for storing credentials of authorized users allowed to access data relating to the devices, and
a data distributor configured to receive a request for data regarding a specific device identified in the request from a user equipment, to access the user credential storage for determining the access rights of the user in question, to determine what parts of the data regarding the identified device the user is authorized to receive, and to allow the user equipment to access the part of the data the user is authorized to access, wherein
at least one of the interface, the data storage, the user credential storage or the data distributor is implemented as one or more electronic circuits or as a combination of circuits and computer programs,
the central data collection apparatus maintains for each device whose data is stored in the data storage a unique identifier which is also available for a user equipment at the installation site of the device in question, and
the central data collection apparatus is configured to retrieve from the request received by the data distributor a unique identifier and if this identifier corresponds to one of the unique identifiers maintained at the central data collection apparatus for one of the devices, identify this device as the device to which the request relates, the unique identifier being available at the installation site of the specific device in a tag including the unique identifier and address information of the central data collection apparatus.

2. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus is configured to change the unique identifier maintained for at least one of the devices according to a predefined process.

3. The central data collection apparatus according to claim 2 , wherein the central data collection apparatus comprises an analyzer configured to analyze the data received for a respective device and to produce one or more diagrams of the analyzed data for distribution by the data distributor in response to requests for data regarding the respective device.

4. The central data collection apparatus according to claim 2 , wherein; the central data collection apparatus is configured to receive a request with a control command for a specific device identified in the request, to access the user credential storage for determining the access rights of the user in question, to determine if the user is authorized to send the control command to the identified device, and to send the control command to the device if the user is authorized to send the control command in question to the identified device.

5. The central data collection apparatus according to claim 2 , wherein the central data collection apparatus is configured to determine that the user does not have any access rights unless the received request indicates that the user of the user equipment has been biometrically identified.

6. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus is configured to communicate with an apparatus at the installation site of the at least one device in order to change the unique identifier maintained by the central data collection apparatus and maintained at the installation site for the at least one device.

7. The central data collection apparatus according to claim 6 , wherein the central data collection apparatus comprises an analyzer configured to analyze the data received for a respective device and to produce one or more diagrams of the analyzed data for distribution by the data distributor in response to requests for data regarding the respective device.

8. The central data collection apparatus according to claim 6 , wherein the central data collection apparatus is configured to receive a request with a control command for a specific device identified in the request, to access the user credential storage for determining the access rights of the user in question, to determine if the user is authorized to send the control command to the identified device, and to send the control command to the device if the user is authorized to send the control command in question to the identified device.

9. The central data collection apparatus according to claim 6 , wherein the central data collection apparatus is configured to determine that the user does not have any access rights unless the received request indicates that the user of the user equipment has been biometrically identified.

10. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus comprises an analyzer configured to analyze the data received for a respective device and to produce one or more diagrams of the analyzed data for distribution by the data distributor in response to requests for data regarding the respective device.

11. The central data collection apparatus according to claim 10 , wherein the central data collection apparatus is configured to receive a request with a control command for a specific device identified in the request, to access the user credential storage for determining the access rights of the user in question, to determine if the user is authorized to send the control command to the identified device, and to send the control command to the device if the user is authorized to send the control command in question to the identified device.

12. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus is configured to receive a request with a control command for a specific device identified in the request, to access the user credential storage for determining the access rights of the user in question, to determine if the user is authorized to send the control command to the identified device, and to send the control command to the device if the user is authorized to send the control command in question to the identified device.

13. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus is configured to determine that the user does not have any access rights unless the received request indicates that the user of the user equipment has been biometrically identified.

14. The central data collection apparatus according to claim 1 , wherein the central data collection apparatus is configured to determine that the user does not have any access rights unless the received request includes secure session identifier which the central data collection apparatus can decrypt with a key to obtain the unique identifier of the device.

15. A method for providing data to a user equipment, comprising:
providing a central data collection apparatus implemented with one or more electronic circuits or as a combination of circuits and computer programs with data relating to devices from control devices arranged at a plurality of different installation sites for monitoring the operation of the respective devices,
maintaining a unique identifier for a specific device available for a user equipment at the central data collection apparatus and at the installation site of the device, and
providing the user equipment with data regarding the spe
