DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display function of a terminal device for realizing an operation console for performing plant monitoring and control, particularly to a screen display using commercially available software.
The present invention relates to a method for controlling the correspondence of a window interaction right (keyboard focus) to a display screen component.

[0002]

2. Description of the Related Art In the past, information has not been directly shared between a supervisory control system that handles information closely related to production and a core information system that handles management information. However, the use of CIM in computer systems has required information sharing between the supervisory control system and the core information system.

A problem in sharing information is that required specifications of the supervisory control system and the core information system are different in terms of usability. The surveillance and control system responds to changes in the situation where attention is being paid to places other than the terminal.
It is required that quick and accurate operations can be performed. That is, it is necessary for the operator to avoid searching for a display element in the screen that is a factor that hinders quick and accurate operation.

[0004] On the other hand, the basic information system is premised on that the operator pays attention to the screen, and is strongly required to express complicated information in an easily understandable manner. Commercial software is often used because of the convenience of information processing and the ease of system construction.

[0005] In order to solve the problem of the divergence in information sharing and usability, in the conventional technology, a terminal whose main task is supervisory control has responded by giving priority to usability for supervisory control. Specifically, although commercially available software is introduced for the FEP function such as Japanese input, the main screen for displaying control information and management information is displayed using software for a control system. In other words, a function specification has been realized that can promptly respond to a sudden change in state in any screen display state by a predetermined direct operation.
Here, the “predetermined direct operation” is not merely a shortcut key. This means that a specific function is activated by pressing a specific key on a physically fixed keyboard which is not affected by the screen display state such as focus. It is an indispensable function for quick and accurate operation even in situations where attention is paid to other than the screen.

Further, as a conventional technique for performing a quick operation on a monitor control screen, there is a technique disclosed in Japanese Patent Application Laid-Open No. Hei 10-254531. With these, it is possible to switch and display the screen quickly with one operation. However, in the screen configuration composed of windows displayed by multiple software, the function that the operation instruction is executed depending on the right to interact with the window is specified. Problems that are not solved will not be solved.

[0007]

When a monitoring screen of a plant is composed of windows generated by a plurality of software, an event when a keyboard is operated is notified to software of a window having a right of dialogue. When operating the keyboard, the operator of the monitoring screen has to switch the conversation right to the window of the software to be operated.

However, in a supervisory control system, it is necessary to activate a specific function by pressing a specific key on a keyboard, which is a "predetermined direct operation". It must be possible to activate a specific function by pressing a specific key on the keyboard.

Further, it is impossible to introduce a process for forcibly capturing a keyboard event in all software constituting the screen of the monitoring and control system when commercial products such as commercial software are introduced. Even in the case of using software whose operation cannot be accepted unless the user has the right to interact with the window, it is possible to realize the activation of a specific function for software that does not have the right to interact with the window.

[0010]

According to the present invention, an event (or message) of a key operated when a specific function of a monitoring screen is activated is notified in advance by an event notification destination setting means. An event notification control unit is provided for setting events in the destination storage memory and controlling events to be notified to software according to the conditions set in the event notification destination storage memory when an event occurs when a key is pressed.

When performing a character input operation from the keyboard on the screen, an alphanumeric key for performing a character input is used to change a notification destination for notifying an event to software of a window having an interactive right of the event notification control means group. Prepare as one.

A method of notifying a plurality of software of a key operation event at the time of performing display contents, enlargement / reduction display, etc. of a screen composed of windows generated by a plurality of software is provided. It is provided as one of the event notification destination control means group.

When the events to be notified to a plurality of software on the screen are different from each other, an event editing means for converting a key operation event into an event corresponding to each software and notifying the event is provided as one of the event notification control means group. Prepare as.

Further, the method for implementing the present invention is a method for starting a specific function from a keyboard on a multi-window plant monitoring control screen including windows generated by a plurality of software, when the window to be operated does not have a dialogue right. An event notification destination setting means for setting a conversion method of an event according to software or each software to which an event is to be notified when a key of a keyboard is pressed in advance. An event notification destination storage memory for storing data, a keyboard event detection unit for obtaining an event generated when a key is pressed, an event notification destination acquisition unit for extracting an event notification method from the event notification destination storage memory, and a keyboard. Events according to the software to be notified And event editing means for conversion,
Event notification means for determining a notification destination of the keyboard event in accordance with the content extracted by the event notification destination obtaining means.

That is, in the first aspect, a notification destination of software for activating a specific function corresponding to a keyboard event is set in advance by the event notification destination setting means, and information for processing the event by the event editing means is set. . When an operation such as switching the display content of the monitoring control screen is performed from the keyboard, the event notification control unit group notifies the keyboard event to predetermined software in accordance with the condition set by the event notification destination setting unit, thereby achieving the desired purpose. Even if the window of the software having the function does not have the interactive right, it can be started.

In the present invention, the notification destination of the key event is fixed to one piece of software by the event notification control means, so that the switching operation of the monitoring screen at the time of the occurrence of the plant state change is impeded by the dialogue right of the window. To prevent that.

According to the third aspect, the event notification control means notifies only predetermined key event notification destinations to predetermined software, thereby preventing switching of the dialogue right of the window. Suppress moving to another window.

According to a fourth aspect of the present invention, the event notification control means switches the notification destination of the key event to a window having the right of dialogue and notifies it, so that the character input operation can be performed on the window having the right of dialogue. I do.

According to a fifth aspect of the present invention, the event notification control means notifies a plurality of software windows constituting the monitoring screen of a display content of the screen and a request for enlarged / reduced display.

According to a sixth aspect of the present invention, when events requested for the plurality of software are different from each other, the key event is converted into an event corresponding to each software by the event editing means.

The display means 19 displays a screen of <example of plant monitoring screen configuration> shown in FIG. This screen configuration includes an alarm display area 22 for displaying the plant monitoring menu screen 21 by the plant monitoring screen control unit 16 to notify an operator of the monitoring screen when an abnormality is detected due to a change in the state of the plant. , A plant monitoring screen group display area 24 for displaying the plant monitoring screen group 17, and a screen development button 23 for selecting a screen to be displayed in the plant monitoring screen group display area 24. Here, as examples of typical screens selected by the screen development button 23, there are the following plant monitoring screen groups, and these buttons can be pressed by pressing a button on the screen with a pointing device such as a mouse, or by pressing () from the keyboard. Can be switched to a target screen by pressing a function key displayed in the display.

• Alarm list (F1) • System diagram (F2) • Trend (F3) • ITV video (F4) • Operation record table (F5) Also, the plant monitoring screen group displayed in the plant monitoring screen group display area 24 Is created by software suitable for each application. For example, the distribution diagram uses graphic editing software and the operation record table uses spreadsheet software. As a result, open operability can be ensured and the number of screen development steps can be reduced.

When an operator on the monitoring screen selects the F5 key to display the operation record table 25 and receives an abnormality notification in the alarm message display area due to a change in the state of the plant, the operator responds to the abnormality of the plant. In order to do so, it is necessary to immediately confirm the state of the plant and correct and change the set values. Normally, when the operation record table 25 is displayed on the spreadsheet software, the dialogue right of the keyboard is switched to this window,
Since all events when the keyboard is operated are notified to the operation record table 25, the operator can temporarily display the system diagram with the F2 key by using the plant monitoring menu screen 21 with the mouse.
Clicking on the title bar, etc., switches to a state where keyboard events are notified.
It is necessary to perform two actions such as pressing the two keys.

Therefore, by specifying the notification destination of the keyboard event by the following method, by pressing the F2 key from the state where the conversation right is set in the operation record table 25, the screen can be switched to the system diagram so that the screen can be promptly changed. It is possible to avoid danger due to screen operation and erroneous operation.

Is used to notify an event when a key on the keyboard is operated to the plant monitoring screen group control unit 16 as a key for selecting a target screen from the plant monitoring screen group such as a function key, or to record an operation record such as an alphanumeric key. Is set in the event notification destination storage memory 12 as information for notifying the plant monitoring screen group as a key for performing a character input on the screen such as.

As an example of this, in FIG.
In step S12, the definition information is extracted from the character string described in the file, and information for identifying the event notification destination is stored in step S12. In step S13, when event codes for performing enlargement / reduction display and display update (redisplay) in the plant monitoring screen group are different for each screen display software, the code of the event to be notified is converted by keyboard operation. The presence / absence of event code conversion information for unifying the information is determined, and these information are stored in steps S14 and S15. The above process is repeated for the definition in step S16, and the defined number is stored in step S17.

In the above description, the method of sequentially analyzing the definition information and storing it in the event notification destination storage memory 12 has been described. The analysis of the definition information is not only performed by sequentially processing the information described in the file or the like, but also by the dialog box. There is also a method of performing batch processing based on input from the like. Further, these setting information can be changed by freely customizing according to a combination of software constituting the screen.

The event notification destination storage memory 12 has a structure shown in FIG. 3, and stores an event code generated when a keyboard is operated and notification destination information of an event corresponding thereto. The notification destination identification information includes information on notification destinations (for example, a process name or the like) that can be identified when the software is running, for the number of notification destinations of the event code.
Event conversion necessity flag, event conversion code, Sh
Stores event modification information such as ift and Ctrl keys.

The keyboard event detecting means 14 is shown in FIG.
In step S21, all event information generated by operating the keyboard (input device) 13 is detected in step S21, and in steps S22 and S23, key event codes and auxiliary keys such as the Shift key and the Ctrl key are pressed. Event modification information is obtained, and the event notification destination acquisition unit 15a is activated in step S24. The processing by the keyboard event detecting means is performed before the event code is notified to the screen display software.

The event notification destination obtaining means 15a searches the event notification destination storage memory 12 for notification destination information corresponding to the event code in step S31 as shown in FIG. If the notification destination information corresponding to the event code exists in step S32, the identification information of the notification destination and the event conversion code as needed are repeatedly extracted in step S33 and S34, and the event editing unit 15b is extracted in step S36. to start.

When the event code conversion is necessary in step S41 as shown in FIG. 7, the event editing means 15b sends the event code to be notified to the software in steps S42 and S43 to the event notification destination obtaining means 15a.
Is converted to the contents extracted by. These processes are performed in step S4 when a plurality of notification destination software are defined.
Repeat as necessary with 4. Next, in step S45, the event notification means 15c is activated to notify predetermined software of the event code.

As shown in FIG. 8, if the event notification destination is designated in step S51 according to the presence or absence of the event notification destination as shown in FIG.
2. In S53, a window for the software to receive the event code is searched from the identification information of the software set in the notification destination identification information, and the event code is notified. In this way, even when a key for switching screens is pressed, an event of a target operation can be received even when the window of the target software does not have the right to interact. On the other hand, if the event notification destination is not specified, the window in which the right of conversation is currently set is searched in steps S55 and S56, and the event code is notified. In this case, by notifying the keys to be set and input to the screen, such as alphanumeric keys, according to the dialogue right of the window,
Enable normal keyboard input operations.

In FIG. 9, the plant monitoring screen group control unit 16
The following shows an example. If the event code received in step S61 is a screen switching request, the currently displayed screen is deleted in step S62, and thereafter, step S6 is performed.
In step 3, a display request is made on the plant monitoring screen according to the event code. In step S64, when the F1 key is pressed, processing for requesting activation of each plant monitoring screen software, such as activation of alarm list display software, is executed.

[0035]

As described above, according to the present invention,
In the plant monitoring and control system, the convenience of information processing and the ease of construction are improved by configuring the screen using commercially available software and other distribution products suitable for the characteristics of the information.
