Abstract

The invention relates to a human-machine interface for a telediagnosis system. The data conversion, the data completion, the data preparation and the computation of a diagnosis result ensue in a central diagnosis center provided in the form of a call center. The computed diagnosis result is displayed in completed form on a display screen whereby enabling a selected assistant in the call center to view the result. The communications expense for the telediagnosis can be considerably reduced, in particular, by the data completion being performed first in the central diagnosis center. As a result, the exchange of complete text files is unnecessary. This enables, in particular, the use of the SMS standard from the mobile radio telephone industry. An error message is conveyed from the technical system to be diagnosed, particularly from the vehicle to be diagnosed, by means of an SMS message. This SMS message is evaluated by a diagnostic program, and a first diagnosis result is computed. This first diagnosis result is automatically converted into an XML structure by the human-machine interface, and is supplemented with additional data concerning the vehicle or from the vehicle according to further evaluation of the first diagnosis result. The data completion automatically ensues once triggered by the original SMS. This diagnosis result supplemented in such a manner and the prepared diagnosis result are displayed on a display screen whereby enabling the assistant in the call center to view the result. This relieves the burden placed upon the assistant of many routine requests for additional information.

Claims

1. Man-machine interface (MMI) for a diagnostic system for diagnosing a technical system with a knowledge base and a diagnostic program that supplies a preliminary diagnostic result in the form of an initial data packet comprising:

a data converter, which converts the initial data packet into an XML structure and saves it as an XML data file on the basis of a converter configuration,

a data completion unit that analyzes the data of the XML data file and reads out additional data by request from the technical system to be diagnosed after setting a manual request and saves it in the XML data file after conversion by means of a completion unit configuration,

and a visualization of the XML elements saved in the XML data file in the form of an inactive user surface.

2. Man-machine interface (MMI) as claimed in claim 1, wherein at least one thesaurus is included and the XML elements are linked to the particular current thesaurus by indices and the text messages from the thesaurus are displayed.

3. Man-machine interface as claimed in claim 1, wherein the visualization is performed by using an Internet browser.

4. Man-machine interface as claimed in claim 1, wherein the initial data packet is comprised of at least one digital vehicle identification number (VIN), an error case identifier (TSID) and a digital time stamp.

5. Man-machine interface as claimed in claim 1, wherein the completion unit configuration contains a logic unit configured for the model series of the particular technical system to be diagnosed, by means of which the required additional model-specific data is determined dynamically on the basis of the data already available and is read out of the technical system on request and stored after being converted into the XML data file.

6. Man-machine interface as claimed in claim 1, wherein the progress display for the status of the data communication with the technical system to be diagnosed is also included.

7. Man-machine interface as claimed in claim 1, wherein several thesauruses in different languages can be used to display the data contents of the XML elements in text form according to the selection made by the user in a selectable language.

8. Man-machine interface as claimed in claim 2, wherein the visualization is performed by using an Internet browser.

9. Man-machine interface as claimed in claim 2, wherein the initial data packet is comprised of at least one digital vehicle identification number (VIN), an error case identifier (TSID) and a digital time stamp.

10. Man-machine interface as claimed in claim 3, wherein the initial data packet is comprised of at least one digital vehicle identification number (VIN), an error case identifier (TSID) and a digital time stamp.

11. Man-machine interface as claimed in claim 2, wherein the completion unit configuration contains a logic unit configured for the model series of the particular technical system to be diagnosed, by means of which the required additional model-specific data is determined dynamically on the basis of the data already available and is read out of the technical system on request and stored after being converted into the XML data file.

12. Man-machine interface as claimed in claim 3, wherein the completion unit configuration contains a logic unit configured for the model series of the particular technical system to be diagnosed, by means of which the required additional model-specific data is determined dynamically on the basis of the data already available and is read out of the technical system on request and stored after being converted into the XML data file.

13. Man-machine interface as claimed in claim 4, wherein the completion unit configuration contains a logic unit configured for the model series of the particular technical system to be diagnosed, by means of which the required additional model-specific data is determined dynamically on the basis of the data already available and is read out of the technical system on request and stored after being converted into the XML data file.

14. Man-machine interface as claimed in claim 2, wherein the progress display for the status of the data communication with the technical system to be diagnosed is also included.

15. Man-machine interface as claimed in claim 3, wherein the progress display for the status of the data communication with the technical system to be diagnosed is also included.

16. Man-machine interface as claimed in claim 4, wherein the progress display for the status of the data communication with the technical system to be diagnosed is also included.

17. Man-machine interface as claimed in claim 5, wherein the progress display for the status of the data communication with the technical system to be diagnosed is also included.

18. Man-machine interface as claimed in claim 2, wherein several thesauruses in different languages can be used to display the data contents of the XML elements in text form according to the selection made by the user in a selectable language.

19. Man-machine interface as claimed in claim 3, wherein several thesauruses in different languages can be used to display the data contents of the XML elements in text form according to the selection made by the user in a selectable language.

20. Man-machine interface as claimed in claim 4, wherein several thesauruses in different languages can be used to display the data contents of the XML elements in text form according to the selection made by the user in a selectable language.
