Abstract

Method and system are provided for processing and presenting on-line, multimedia information such as diagnostic information for a machine tool. The system uses multimedia information tools (i.e. graphics, documentation, drawings, photographs, full motion video with audio, PLC ladder, etc.) and techniques to assist maintenance personnel. Diagnostic development and multimedia information assignment are accomplished through graphical visual programming, which requires no conventional software programming efforts. The system uses diagnostic trees having multimedia graphic icons which define the diagnostic components. In developing a visual diagnostic tree, the multimedia information can be assigned or mapped to each node of the tree by selecting an appropriate icon to represent the multimedia from an icon library. Then, an appropriate media information file or record and comments for that icon are further added to define that node assignments. The system is user friendly, uses conventional hardware and can be used on the plant floor. The system is immediately executable and is generic. The method and system can also be used for training, process planning, marketing, sales, help desk applications, other machine diagnostics, and engineering design.

7. The method as claimed in claim 1 wherein the multimedia information includes video images.

8. The method as claimed in claim 1 wherein the multimedia information includes sound messages.

9. The method as claimed in claim 1 wherein the multimedia information includes drawing images.

10. The method as claimed in claim 1 wherein the multimedia information includes graphical images.

11. The method as claimed in claim 1 wherein the multimedia information includes images of documents.

12. The method as claimed in claim 1 wherein a multiplicity of digitized video images is stored, each of the stored video images corresponding to one or more pieces of equipment from a predefined set of pieces of equipment.

13. The method as claimed in claim 1 wherein the multimedia commands are displayed in the form of graphic icons.

14. The method as claimed in claim 1 wherein the initial command is a user command.

15. The method as claimed in claim 1 wherein the selected nodes of the tree structure are displayed.

16. The method as claimed in claim 1 wherein the information records further include means for denoting graphical images to be displayed.

17. A system for processing and presenting multimedia diagnostic information as a diagnostic tree structure including branches having a plurality of nodes and node-connecting links in a computer system having tree display means for displaying a graphical representation of nodes of the tree structure, the system comprising:

command display means for displaying multimedia diagnostic commands representative of various types of multimedia diagnostic information;

multimedia output means for providing multimedia diagnostic information to a user of the system;

a knowledge base for storing a multiplicity of diagnostic information records mapped into the diagnostic tree structure, the diagnostic information records including;

information records denoting the text strings to be displayed on the tree display means;

information records denoting the multimedia commands to be displayed on the command display means; and

information records denoting the multimedia information to be presented by said multimedia output means;

means for receiving an initial command, the tree display means displaying a plurality of nodes including a question and answer node of the tree structure including at least one text string in response to the initial command, and the command display means displaying a plurality of multimedia diagnostic commands corresponding to the question and answer node on the command display means; and
