Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process monitor / control device for monitoring / controlling a process by a plurality of terminals connected to a network.

[0002]

2. Description of the Related Art As shown in FIG. 6, a process monitor / control device of this type includes a display monitor device 2 on a network 1,
An engineering workstation (hereinafter abbreviated as EWS) 3 attached with a CRT display device 16 is connected as a terminal, and in any of these terminals,
It is now possible to monitor and control the processes of large-scale plants.

Here, the display monitoring device 2 has a CRT display device internally as its constituent element, while E
The difference is that a CRT display device 16 is externally connected to WS3. However, both the hardware configurations can be expressed by the block diagram of FIG. 7. That is, using the keyboard 11 and the mouse 12 as input means, the input control unit
A setting signal, an operation signal and the like are sent to the main control unit 14 via 13, while the main control unit 14 displays signals such as process state quantity and setting quantity on the CRT display via the output control section 15. It is configured to be sent to the device 16 and displayed.

By the way, the keyboard 11 constituting the display monitoring device 2 is arranged with keys for remote operation, which are also called function keys, and the main control section 14 stores processing functions corresponding to the respective keys. On the other hand, the keyboard 11 constituting the EWS 3 is an array of standard keys used in a general-purpose computer or the like, and therefore, the main controller 14 stores processing functions according to its operating procedure. The two differ in points.

On the other hand, in both the display monitoring device 2 and the EWS 3, the current state quantity is displayed on the display screen of the CRT display device 16 by a bar graph, and correspondingly, the set value is displayed by a marker, and , It had a function to change the set value by moving the position with the mouse.

[0006]

In the above-described conventional process monitoring / controlling apparatus, when the set value is input in the display / monitoring apparatus 2, the set value can be set or changed by pressing the remote operation key corresponding to the process. On the other hand, in EWS3, there is a problem in that the promptness of the operation is lacking because the process is selected and the numerical value is input in conversation.

The display monitor 2 has a function of simultaneously changing the set values of a plurality of processes.
In No. 3, since the setting operation is performed for each process, there is a problem that the set values of a plurality of processes cannot be changed at the same time.

Further, as is common to the display monitoring device 2 and the EWS 3, when the marker is moved by the mouse to change the set value, the ratio of the moving amount of the mouse to the moving amount of the marker is constant. Therefore, there is also a problem that a great deal of attention or time is required for a small amount change or a large amount change.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a process monitoring / controlling device capable of improving the operability when setting and changing a set value.

A process monitoring / control apparatus according to a first aspect of the present invention represents a set value for control and monitoring by a position of a marker displayed on a screen of a display device, and corresponds to the set value. The first and second terminals capable of visually expressing the state quantity by a bar graph or the like and capable of moving the marker using at least a keyboard and a mouse as input means are connected to a network, and the keyboard of the first terminal has a predetermined size. When the keyboard of the second terminal has standard keys, the second terminal has a keyboard in which the remote operation keys are arranged on its display device. When the keyboard display means for displaying the window and the remote operation key displayed in the window are selected with the mouse, the remote operation key is displayed. It is characterized in that a key corresponding processing means for executing processing corresponding to.

According to another aspect of the present invention, there is provided a process monitoring / controlling apparatus which expresses a set value of a control target or a monitored object according to a position of a marker displayed on a screen of a display device, and displays a state quantity corresponding to the set value in a bar graph or the like. Visually expressed by
At least first and second terminals capable of moving a marker using a keyboard and a mouse as input means are connected to a network, and the keyboard of the first terminal has a remote operation key to which a predetermined processing function is assigned. However, when the keyboard of the second terminal has a standard key, at least one of the first and second terminals displays a marker segmentation display means for segmenting and displaying the marker into a plurality of segments, and a marker segmentation area. Of these, a movement amount identifying means for displaying the area selected by the mouse in a distinctive manner, and a marker movement amount changing means for changing the ratio of the movement amount of the mouse to the movement amount of the marker corresponding to the divided area of the marker. It is characterized by having prepared.

[0012]

In the process monitoring / controlling apparatus according to the first aspect, the second terminal displays on the display unit a keyboard in which remote operation keys are arranged in a window, and selects the remote operation key with a mouse. When this is done, the processing corresponding to the remote operation key is executed, so that quickness of operation that cannot be obtained with the keyboard in which the standard keys are arranged can be obtained, and it corresponds to the remote operation key sequentially selected by the mouse. It is also possible to execute the above-mentioned processes at the same time, and the operability is improved.

Further, in the process monitoring / controlling apparatus according to the second aspect of the invention, the ratio of the movement amount of the mouse to the movement amount of the marker depends on which area of the marker divided into a plurality of areas is selected by the mouse. Since it is changed, it is easy to change a small amount or a large amount of the set value, and the operability is improved.

The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 shows the process monitoring according to claim 1.
It is a block diagram which shows the structure of the Example corresponding to a control apparatus, and has shown especially the structure of EWS3. In the figure, the same elements as those of FIG. 7 are designated by the same reference numerals, and detailed description thereof will be omitted. Then, the keyboard display means 21 is provided on the main control unit 14.
7 and that the key correspondence processing means 22 is newly added.

Here, the keyboard display means 21 is for displaying a keyboard screen in which remote operation keys are arranged on the CRT display device 16 as a window, and the key correspondence processing means 22 is for processing corresponding to each key displayed on the screen. It stores functions. Then, when a key on the display screen of the CRT display device 16 is selected by the mouse 12, it is configured to execute the same process as if the keyboard on which the remote operation keys constituting the display monitoring device 2 are arranged is operated. Has been done.

FIG. 2 shows an example of a display screen for setting and changing set values using these functions. A remote operation keyboard window 30 is displayed at the top of the screen. Here, a set of remote operation keys 31 is arranged horizontally for each process, and at the right end, there are three types of keys for setting the speed of the set value, namely, "Fast" and "Norm".
The keys "al" and "Slow" and the key for instructing the execution of the setting operation for each set value, that is, the "Act" key are arranged. In addition, processes A, B, and
The state quantities 41A, 41B, ..., 41H are displayed for each of ~, H in a bar graph, and the corresponding set values are displayed by the markers 42A, 42B, ~, 42H.

If any of the keys corresponding to each process is selected by using the mouse 12, that is, the cursor is moved to the key and the button is clicked, and then the "Act" key is selected, the setting process is performed. Is executed. In this case, if the setting value is set or changed, "Fast", "Norma"
If either "l" or "Slow" is selected and then the remote operation key 31 is selected, the markers 42A, 42B, ..., 42H, etc. move up and down in accordance with the selected speed. After performing such marker movement operations for multiple processes, select the "Act" key to execute the setting process at the same time.

As is clear from the above description, according to this embodiment, even in the terminal using the EWS 3, the same operation as that of the display monitoring apparatus 2 having the remote operating keyboard can be performed. As a result, when setting or changing the set value, quick and accurate operation can be performed, and at the same time, setting operation for a plurality of processes can be performed.

FIG. 3 is a block diagram showing the configuration of an embodiment corresponding to the process monitoring / controlling apparatus according to the second aspect. In the figure, the same elements as those in FIG.
The detailed description is omitted. 7 is different from the configuration shown in FIG. 7 in that a marker division display means 23, a marker movement amount changing means 24, and a movement amount identifying means 25 are newly added to the main controller 14.

Marker segmentation display means 23 newly added
4B, as shown in FIG. 4B, the marker 52 displayed on the CRT display device 16 is divided into three, and the marker movement amount changing means 24 is divided into the divided areas A,
The ratio between the movement amount of the mouse 12 and the movement amount of the marker 52 is changed depending on which one of B and C is selected. Further, the movement amount identifying means 25 is selected from the areas A, B and C. In order to distinguish the marked area from others, for example, a process of changing the color is performed.

In this embodiment, the marker 52 is moved slowly or swiftly in response to a slight change or a large change in the set value. In this case, as shown in FIG. 4 (a), the marker 52 displayed on the side corresponding to the state quantity 51 of the process is displayed by the marker dividing display means 23 as shown in FIG. 4 (b). Are displayed separately in three areas A, B, and C. Then, the marker movement amount changing means 24, when the area A is selected by the mouse 12,
The movement amount of the marker 52 becomes “large” with respect to the movement amount of the mouse 12, and when the region B is selected, the movement amount of the marker 52 is “medium”.
Therefore, when the area C is selected, processing is performed so that the movement amount of the marker 52 becomes “small”. At this time, the movement amount identification means 25 changes the display state of the selected area so that it can be discriminated from others, and informs the operator of the movement speed of the marker.

FIG. 5 is a flow chart showing the processing procedure of the main control section 14 corresponding to the marker movement amount changing means 24. Here, in the first step 101, it is determined whether or not the marker is selected by the mouse, and if it is selected, the step
At 102, it is determined which of the areas A, B, and C the position is. If not selected, the process returns to the first process.

If the area determined in step 102 is the A area on the left side of the screen, the movement amount is increased in step 103, and if the determined area is the B area in the center of the screen, the movement amount in step 104. If the determined area is the C area on the right side of the screen, the movement amount is reduced in step 105. After performing the process for these movement amounts, the process returns to the first process.

Thus, according to this embodiment, it is possible to perform an accurate setting operation in which the moving amount of the marker is reduced and a rapid setting operation in which the moving amount of the marker is increased. The function shown in this embodiment is not limited to the EWS 3 and may be provided in the display monitoring device 2.

In addition, in each of the above-mentioned embodiments, the one using the CRT display device as the display device is targeted.
Instead of the display device, it can be applied to a device using another display device such as a liquid crystal display device.

[0026]

As is apparent from the above description, according to the process monitoring / controlling apparatus of the first aspect, even a terminal without a remote operation keyboard can be operated in the same manner as a terminal with a remote operation keyboard. Promptness is ensured, and a plurality of processes can be executed at the same time, so that operability is significantly improved.

Further, according to the process monitoring / controlling apparatus of the second aspect, the ratio of the movement amount of the mouse to the movement amount of the marker depends on which area of the marker divided into a plurality of areas is selected by the mouse. Since it is changed, it becomes easy to change a small amount or a large amount of the set value, and the operability is remarkably enhanced.
