Abstract

A display system is disclosed for graphic representation of alarm reports from measured values of a technical plant or technical process, with a processing device, wherein the measurement points of the measured values each have a hierarchically structured identifier, and the hierarchically structured identifier of the relevant measurement points is held in the processing device. The processing device decomposes the hierarchically structured identifiers of the measurement points into hierarchical levels of different significance, selects the identifiers of the hierarchical levels of the measurement points with the highest significance, and transmits them to a preconfigured mass alarm display unit. The identifiers of the hierarchical levels with the highest significance can be assigned to a correspondingly identified area within an overview image of the plant or process of the preconfigured mass alarm display unit. The alarm reports which are generated from the measured values can be represented graphically, taking account of the generated assignment of the identifier of the measurement points to the correspondingly identified area within the overview image of the plant or process.

Claims

1. Display system for graphic representation of alarm reports from measured values of a technical plant or technical process, with a processing device, wherein

the measurement points of the measured values each have a hierarchically structured identifier,

the hierarchically structured identifiers of the measurement points are held in the processing device,

the processing device decomposes the hierarchically structured identifiers of the measurement points into hierarchical levels of different significance, selects the identifier of the hierarchical level of the measurement point with the currently highest significance, and transmits the selected identifiers to a preconfigured mass alarm display unit,

the selected identifiers of the relevant measurement point can be assigned to a correspondingly identified area within an overview image of the preconfigured mass alarm display unit, and

the alarm reports which are generated from the measured values can be represented graphically, taking account of the generated assignment of the selected identifiers of the measurement points to the correspondingly identified area within the overview image of the plant or process.

2. Display system according to claim 1, wherein the mass alarm display unit is provided to represent mass alarms, particularly process alarms.

3. Display system according to claim 1, wherein the mass alarm display unit is preconfigured so that the overview image which is represented by means of the mass alarm display unit is divided into areas, and a primary key, which defines the visual effects with which the areas of the plant image make the process states which occur visible, is assigned to each of these areas.

4. Display system according to claim 1, wherein the visual effects can be transmitted, according to a defined mapping rule, into the corresponding areas of the plant image.

5. Display system according to claim 1, wherein the overview image of the plant or process can be shown on the mass alarm display unit as a process-state-driven, dynamically generated, visually sophisticated computer graphic.

11. Display system according to claim 2, wherein the mass alarm display unit is preconfigured so that the overview image which is represented by means of the mass alarm display unit is divided into areas, and a primary key, which defines the visual effects with which the areas of the plant image make the process states which occur visible, is assigned to each of these areas.

12. Display system according to claim 3, wherein the visual effects can be transmitted, according to a defined mapping rule, into the corresponding areas of the plant image.

13. Display system according to claim 4, wherein the overview image of the plant or process can be shown on the mass alarm display unit as a process-state-driven, dynamically generated, visually sophisticated computer graphic.

6. Method of graphic representation of alarm reports from measured values of a technical plant or technical process, with a processing device, wherein

a hierarchically structured identifier is assigned to each of the measurement points of the measured values of the technical plant or technical process, and the hierarchically structured identifiers of the measurement points are held in the processing device,

by means of the processing device, the hierarchically structured identifiers of the measurement points are decomposed into hierarchical levels of different significance, the identifier of the hierarchical level of the measurement point with the highest significance is selected, and the selected identifiers are transmitted to a preconfigured mass alarm display unit,

the selected identifiers are assigned to a correspondingly identified area within an overview image of the preconfigured mass alarm display unit, and

the alarm reports which are generated from the measured values are represented graphically, taking account of the generated assignment of the selected identifiers of the measurement points to the correspondingly identified area within the overview image of the plant or process.

7. Method according to claim 6, wherein mass alarms, particularly process alarms, are represented by means of the mass alarm display unit.

8. Method according to claim 6, wherein the mass alarm display unit is preconfigured so that the plant image which is represented by means of the mass alarm display unit is divided into areas, and a primary key is assigned to each of these areas, the visual effects with which the areas of the plant image make the process states which occur visible being defined taking account of the assigned primary key.

9. Method according to claim 6, wherein the visual effects are transmitted, according to a defined mapping rule, into the corresponding areas of the plant image.

10. Method according to claim 6, wherein the overview image of the plant or process is shown on the mass alarm display unit as a process-state-driven, dynamically generated, visually sophisticated computer graphic.

14. Method according to claim 7, wherein the mass alarm display unit is preconfigured so that the plant image which is represented by means of the mass alarm display unit is divided into areas, and a primary key is assigned to each of these areas, the visual effects with which the areas of the plant image make the process states which occur visible being defined taking account of the assigned primary key.

15. Method according to claim 8, wherein the visual effects are transmitted, according to a defined mapping rule, into the corresponding areas of the plant image.

16. Method according to claim 9, wherein the overview image of the plant or process is shown on the mass alarm display unit as a process-state-driven, dynamically generated, visually sophisticated computer graphic.

17. A method of graphic representation of alarm reports from measured values with a processing device, comprising:

assigning a hierarchically structured identifier to measurement points of the measured values, the hierarchically structured identifiers of the measurement points being held in the processing device,

by means of the processing device, decomposing the hierarchically structured identifiers of the measurement points into hierarchical levels of different significance, and selecting an identifier of the hierarchical level of the measurement point having a high significance, and transmitting the selected identifiers to a preconfigured mass alarm display unit,

assigning the selected identifiers to a correspondingly identified area within an overview image of the preconfigured mass alarm display unit, and

graphically representing alarm reports which are generated based on the measured values.
