Method and device for controlling user dialog on technical equipment

A device (DVC) for controlling user dialogs on a technical equipment (ATM) to be serviced for maintenance, wherein the device has a computing unit (COMP) that evaluates data (D) about the condition of the technical equipment (ATM) and, depending on said evaluation, controls at least a visual output of textual and/or pictorial instructions (INSTR;

• CHK) for a user maintaining the technical equipment (ATM), characterized in that the computing unit (COMP) processes the data (D) using a directed graph (GRPH) that controls nodes (1000, . . . , 1300 . . . ) and edges (INSTR, CHK) connecting the nodes, wherein the nodes relate to different maintenance conditions of the equipment (ATM), and the edges relate to instructions to the user for transferring the equipment (ATM) from one of the nodes to another node.

The device (DVC) from claim 8, wherein at least the computing unit (COMP) is located remotely from the equipment (ATM) and is connected through a data interface (IF) to at least one sensor (S) mounted in the equipment by means of which the data (D) about the condition of the technical equipment (ATM) are determined.

Technical equipment (ATM) comprising a device (DVC) for controlling user dialogs on a technical equipment (ATM) to be maintained, wherein the device has a computing unit (COMP) that evaluates data (D) about the condition of the technical equipment (ATM) and, based on said evaluation, controls at least a visual output of textual and/or pictorial instructions (INSTR:

• CHK) for a user maintaining the technical equipment (ATM), characterized in that the computing unit (COMP) processes the data (D) using a directed graph (GRPH) that comprises nodes (1000, . . . , 1300 . . . ) and edges (INSTR, CHK) connecting the nodes, wherein the nodes relate to different maintenance conditions for the equipment (ATM), and the edges relate to instructions for the user for transferring the equipment (ATM) from one of the nodes to another node.
