2. Description of the Related Art Conventionally, there is a plant control system called a distributed control system for performing control operation and monitoring of a plant using a CRT display device. Such a plant control system displays various information necessary for plant control and operation on a screen of a CRT display device,
When an abnormality occurs in the plant, a warning is displayed to notify the operator of the abnormality, and the operator can perform an appropriate instruction or action for the abnormality.

The operation monitoring station in the plant control system has provided a dedicated graphic display device for operation monitoring. Conventionally, there has been the following means for generating an optimum screen for an operator using this graphic display device. (Conventional example 1) Means in which necessary primitives (drawing elements) are previously arranged on a graphic screen using a dedicated graphic builder (graphic screen construction tool). (Conventional example 2) A means for calling a basic graphic screen and dynamically adding various windows on the screen as needed during operation. The various windows are individual primitives that are small windows.

In the prior art example 1, when constructing a graphic screen, the operation mode of the operator cannot be foreseen yet and has not been determined, so that it is difficult to prepare an optimal screen using a graphic builder in advance. there were. In addition, the graphic screen can be corrected as needed using the graphic builder, but a series of operations for the correction are complicated. In the second conventional example, the operator can add a necessary window even after constructing the graphic screen, so that there is no trouble in constructing the screen. However, once the screen is switched to another graphic screen, the added window disappears. Therefore, the next time the original graphic screen is called, the necessary window must be added again. As a result, there is a problem that the efficiency of the operation is significantly reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention.
In FIG. 1, reference numeral 1 denotes a display unit for displaying an operation monitoring screen, and 2 and 3 denote a master window memory and a slave window memory storing a master window and a slave window, respectively. The master window is a main screen for operation monitoring, and the operator monitors the operation of the plant centering on this screen. The screen here is 1
One window. The slave window is a window called depending on the master window, and provides auxiliary information to the master window. Reference numeral 4 denotes window calling means for independently calling the master window and the slave window on the same screen. There is one master window called on one screen,
The number of slave windows may be one or more.

Reference numeral 5 denotes a window management server that manages the calling relationship between the master window and various slave windows. In the window management server 5, reference numeral 51 denotes a window management means for managing, as window set information, information indicating the screen configuration such as the type, content, size, and position of the master window and the slave window called on the screen; Storage instruction means for instructing the storage of the configuration. Reference numeral 53 denotes a storage unit, which stores window set information in the window set information memory 54 as information dependent on the master window when the storage instruction unit 52 gives an instruction to save the screen configuration. 55 is a reproducing means, when the master window is called, reads window set information dependent on the called master window from the window set information memory 54, and reads out the window set information from the master window and the slave window based on the read window set information. Reproduce the screen configuration. The storage instructing means 52 and the reproducing means 55 are constituted by input means such as a key and a mouse.

The operation of the apparatus shown in FIG. 1 will be described. FIG. 2 shows FIG.
FIG. 7 is a diagram showing an example of a screen displayed on the device of FIG. The operation monitoring screen includes a master window and a slave window. The window management server dynamically manages the relationship between the master window and the slave window. FIGS. 2A to 2E are views showing the order in which the screen is developed. The description will be made according to this order.

(A) Nothing is displayed on the screen. (B) Call the master window T1. (C) Further, the slave windows S1 and S2 are added. When a “save operation” is performed by pressing the save key or the like while displaying this screen, the window management server
Master window and slave window types, contents,
Information indicating the screen configuration such as size and position is stored as window set information. (D) Call another master window T2. At this time, the master window T1 and the slave window S
1, S2 are erased. (E) When the master window T1 is called again, the window management server automatically sets the window set, that is, the master window T1 and the slave window S.
1 and S2 are reproduced with the original screen configuration. When the screen configuration is saved in this way, when the original screen is called after being developed on another screen, the master window and the slave window are reproduced with the original screen configuration.

[0011]

According to the present invention, the screen configuration constructed using windows is stored as information, and when the screen is called again, the original screen configuration is reproduced based on the stored information. For this reason, only the screen including the minimum functions needs to be prepared in advance, and the work in the previous process can be reduced. Then, the screen configuration can be saved simply by calling a dedicated window (one in which individual primitives have become windows) on the prepared screen and performing a save operation. When the screen is called, the saved screen configuration can be reproduced. Therefore, by dynamically managing the standard screen and various windows, it is possible to gradually construct an optimal screen configuration according to the plant operation system.
Therefore, according to the present invention, it is possible to easily construct an optimum screen configuration for operation monitoring for the operator.
