Abstract

A display system includes a display device in production equipment. The display device includes a control unit, a display unit, a storage unit, and an input unit. The storage unit stores: schematic illustration data that represent a schematic illustration of the production equipment; and causal relationship model data in which one or more cause elements of one or more abnormalities that can occur in the production equipment are selected from driving means for driving the production equipment and monitoring means for monitoring the production, and the cause elements and the relationships between the cause elements are represented as a causal relationship model. The control unit displays the schematic illustration and the causal relationship model on the display unit such that the causal relationship model is superimposed on the schematic illustration so as to correspond to the schematic illustration.

First claim

1 . A display system provided in production equipment that produces a product and includes one or more driving means configured to perform driving of the production equipment and one or more monitoring means configured to perform monitoring of the production, the display system comprising:
a control unit; a display unit; and a storage unit, wherein the storage unit stores: schematic illustration data representing a schematic illustration of the production equipment; and causal relationship model data in which one or more cause elements of one or more abnormalities that can occur in the production equipment are selected from among the driving means and the monitoring means and represented as a causal relationship model together with a relationship between the cause elements, and the control unit is configured to display the schematic illustration and the causal relationship model on the display unit so that the causal relationship model is superimposed on the schematic illustration so as to correspond to the schematic illustration.

2 . The display system according to claim 1 , further comprising:
an input unit, wherein the storage unit stores causal relationship model data related to a plurality of the abnormalities, the input unit is configured to receive a selection of one abnormality from the plurality of abnormalities, and the control unit is configured to display the causal relationship model corresponding to the selected abnormality on the display unit.

3 . The display system according to claim 1 ,
wherein the driving means and the monitoring means have one or more controllable feature quantities, and the control unit displays the cause element of each abnormality and the one or more feature quantities corresponding to the cause elements as a list on the display unit.

4 . The display system according to claim 3 ,
wherein an input unit receives a selection of one of the cause elements from the list, and the control unit is configured to highlight the selected cause element in the causal relationship model displayed on the display unit.

5 . A display method for displaying, on a display unit, a causal relationship of abnormalities that can occur in production equipment, the production equipment producing a product and including one or more driving means configured to perform driving of the production equipment and one or more monitoring means configured to perform monitoring of the production, the display method comprising:
storing schematic illustration data representing a schematic illustration of the production equipment; storing causal relationship model data in which one or more cause elements of one or more abnormalities in the production equipment are selected from among the driving means and the monitoring means and represented as a causal relationship model together with a relationship between the cause elements; and displaying the schematic illustration and the causal relationship model on the display unit so that the causal relationship model is superimposed on the schematic illustration so as to correspond to the schematic illustration.

6 . A non-transitory computer-readable recording medium, recording a display program for displaying, on a display unit, a causal relationship of abnormalities that can occur in production equipment, the production equipment producing a product and including one or more driving means configured to perform driving of the production equipment and one or more monitoring means configured to perform monitoring of the production, the display program causing a computer to execute:
storing schematic illustration data representing a schematic illustration of the production equipment; storing causal relationship model data in which one or more cause elements of one or more abnormalities in the production equipment are selected from among the driving means and the monitoring means and represented as a causal relationship model together with a relationship between the cause elements; and displaying the schematic illustration and the causal relationship model on the display unit so that the causal relationship model is superimposed on the schematic illustration so as to correspond to the schematic illustration.
