Abstract

In a large-scale plant such as a power plant, a graphical user interface device displays a target data display screen without increasing a load of searching a screen or a load of grasping a screen transition link. An operation model-creating device reads operation manual data for operation estimation and operation history data from an operation manual managing device and an operation history managing device to create a number of pieces of manual procedure template data for each accident type. An operation predicting device selects the operation procedure template data having same conditions of immediately preceding operation history data obtained from the plant monitoring and control device to predict the next operation estimated to be performed by an operator from the selected operation procedure template data. The plant monitoring and control device displays a system recommended operation button on a monitoring screen thereof based on data of the predicted results.

Claims

1. A graphical user interface device in a monitoring and control system that monitors and controls a plant, the graphical user interface device comprising:

a memory device in which pieces of operation manual data including descriptions regarding operation targets and operation details are registered, the descriptions being arranged in an order of operation procedure;

a database in which device IDs indicating devices being said operation targets and operation IDs indicating said operation details are registered; and

an operation model creating device automatically creating, from said operation manual data, operation procedure template data including information of one or multiple operation procedures and device IDs and operation IDs corresponding to respective procedures of the operation procedure for each type of a handling operation to register the operation procedure template data in the memory device,

wherein the graphical user interface device is configured to select, by a pattern matching processing of said operation procedure template data and plant measurement data including device IDs and operation IDs respectively corresponding to multiple immediately-preceding successive operations, operation procedure template data having a high degree of coincidence with said immediately preceding operation, and estimate a type of a handling operation currently executed by an operator and subsequent operation details, to thereby display, on a display section of said monitoring and control system, guidance information based on a device ID and an operation ID corresponding to the estimated subsequent operation details.

2. The graphical user interface device according to claim 1, wherein said operation model creating device is configured to perform a pattern matching processing of said operation procedure template data and operation history data including device IDs and operation IDs, and create, in a case where a procedure of the operation or a device differs between the existing operation procedure template data and said operation history data, new operation procedure template data corresponding to said operation history data to automatically add and register the new operation procedure template data to the memory device.

3. The graphical user interface device according to claim 1, wherein said operation model creating device is configured to identify multiple successive operations appearing with a high frequency from operation history data including device IDs and operation IDs, and automatically add and register the multiple successive operations as operation procedure template data to the memory device.

4. The graphical user interface device according to claim 1, wherein said plant monitoring and control device includes, on a plant monitoring screen:

a system setting operation button display section making no change in a screen transition link unless system setting is changed; and

a system recommended operation button display section using an operation ID and a device ID corresponding to a subsequent operation of said immediately preceding operation in the operation procedure template data having a high degree of coincidence with said immediately preceding operation to change the screen transition link in real time.

5. The graphical user interface device according to claim 2, wherein said plant monitoring and control device includes, on a plant monitoring screen:

a system setting operation button display section making no change in a screen transition link unless system setting is changed; and

a system recommended operation button display section using an operation ID and a device ID corresponding to a subsequent operation of said immediately preceding operation in the operation procedure template data having a high degree of coincidence with said immediately preceding operation to change the screen transition link in real time.

6. The graphical user interface device according to claim 3, wherein said plant monitoring and control device includes, on a plant monitoring screen:

a system setting operation button display section making no change in a screen transition link unless system setting is changed; and

a system recommended operation button display section using an operation ID and a device ID corresponding to a subsequent operation of said immediately preceding operation in the operation procedure template data having a high degree of coincidence with said immediately preceding operation to change the screen transition link in real time.
