【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. First Embodiment FIG. 1 is a block diagram showing a device configuration of a man-machine device for supervisory control according to a first embodiment of the present invention. In the figure, 1 is a processing task for performing supervisory control of a plant or the like to be monitored based on system specifications, and 2 is a C task.
The operator input / output unit is formed by the RT display 11, the touch panel 12, the keyboard 13, and the like, and performs input / output for monitoring control with an operator. 3 processes input events from the processing task 1 and the operator input / output means 2,
Is a display / operation means for processing an output to the operator input / output means 2 to display a screen and process an operation. Reference numeral 4 is a component holding means for holding display / operation components defining information for configuring functions such as screen display and operation as one processing unit, and 5 is a component for managing / processing the display / operation components. It is a processing means.

Next, the operation will be described. The display / operation parts are defined as a table of attributes that can be changed and attributes that cannot be changed, and are held in the parts holding means 4. The attributes that can be changed are the position, size, color, and
There are character strings, character types, etc., and the attributes that cannot be changed include the content of processing performed by the display / operation component such as sending of an input event. FIG. 2 is an explanatory diagram showing an example of setting the attributes of the display / operation parts, and each is the “basic drawing test”.
3 shows an example of setting the attributes of two button parts of a character string "and message display". When the apparatus is activated, the component processing means 5 reads the component holding means 4 and determines the attribute value of each display / operation component according to the setting of FIG.

The operation at startup will be described below with reference to the flowchart shown in FIG. When the monitoring control man-machine device according to the first embodiment is activated, first, the display / operation means 3 displays a screen based on the setting of the initial display (step ST1). The setting of this initial display consists of setting of display / operation parts, and the display / operation means 3 instructs the parts processing means 5 to set the display / operation parts according to the settings (step ST2). The component processing means 5 reads the definition of the designated display / operation component from the component holding means 4 and copies it inside (step ST3).
Next, the component processing means 5 sets the actual value to the attribute of the display / operation component based on the designation (step ST4). Based on this setting, the component display means 5 displays and operates the display / operation means 3.
The display / operation part 3 displays the display / operation part on the CRT display 11 of the operator input / output means 2 (step ST).
5). After that, the state of waiting for an input event from the operator input / output unit 2 or the processing task 1 is entered (step ST6), and thereafter, the processing of the input event from the operator is performed through the display / operation parts displayed on the CRT display 11. Further, the output from the processing task 1 is also performed through the display / operation components held by the component processing means 5.

Next, the operation when the operator tries to display the current plant state on the processing task 1 in the state of waiting for an input event will be described with reference to FIGS. 4 and 5. Here, FIG. 4 is an explanatory diagram showing the occurrence of an input event from the operator input / output means 2, and FIG. 5 is a flowchart showing the flow of the component processing thereafter. When the operator wants to display the current plant state, as shown in FIG. 4, the operator places a button component 21 on the touch panel 12 that is a display / operation component that calls the plant state display function displayed on the CRT display 11. Touch more. As a result, an input event from the operator input / output means 2 occurs (step ST11), and the display / operation means 3 operates on the touch panel 1
The input event from 2 is transmitted to the component processing means 5 (step ST12). The part processing means 5 which received it checks its state using the attribute acquisition function of the button part 21 itself which has generated the input event, and whether the state of the button part 21 can call the plant state display screen. It is determined whether or not (step ST13).

If the call is possible, the parts processing means 5 requests the processing task 1 to check the plant status by the event transmission function of the button part 21 (step ST14). Receiving it, the processing task 1 checks the current plant state, and requests the component processing means 5 to call a display / operation component having a plant state display function together with data indicating the plant state (step ST15). . Based on this, the parts processing means 5 calls the plant status display parts from the parts holding means 4 and passes the data indicating the status of the plant sent from the processing task 1 to the plant status display parts (step ST16). Thereafter, the parts processing means 5 requests the display / operation means 3 to display the plant status by using the drawing function of the plant status display parts, and the display / operation means 3 sends it to the CRT display 11 of the operator input / output means 2.
A screen is displayed above (step ST17).

On the other hand, if the call is impossible,
The component processing means 5 calls from the component holding means 4 a message display component for displaying a message that the screen display of the plant state is impossible (step ST18).
Next, pass the message to the message display component,
The display / operation unit 3 is requested to display the message using the message display function of the message display component (step ST19). The display / operation means 3 draws the message on the CRT display 11 of the operator input / output means 2 in accordance with the received instruction (step ST20).

Here, a concrete display / operation component and an operation example for the same will be described. Figure 6 shows a concrete display
It is explanatory drawing which shows an operation component, and the figure (a) has shown the button component. In the figure, reference numeral 22 is a button component (display / operation component) for notifying whether or not the operator has pressed it. When this button component 22 is touched through the touch panel 12, the display / operation means 3 notifies the component processing means 5 that it has been pressed. The component processing means 5 checks the attribute of the button component 22 and calls a processing function when the button is pressed (requests the processing task 1 to perform some processing, changes the attribute of the component itself, etc.) and performs component processing. . Further, FIG. 6B shows a label component for displaying a character string, and 23 is the label component (display / operation component).
Is. This is used for displaying a message in response to a display request from the processing task 1 or the like. The label component 23 that has received the display request from the processing task 1
The display / operation means 3 is requested to draw a character string having an attribute therein by using its own drawing function. Furthermore, FIG.
(C) shows a separator part. In the figure, 2
Reference numeral 4 denotes the separator component (display / operation component), which indicates a partition between components. Reference numeral 25 is various parts, and 26 is a part display part (display / operation part) for displaying the part 25. The separator component 24 can be changed in length, position, etc., and as shown in the figure, the component display component 26
When used in combination with, it is possible to deal with changes in size freely.

In the conventional man-machine device for monitoring and control, the processing task performs all processes such as screen display, input processing, and plant operation. Therefore, when the specification of display / operation is changed, the plant is temporarily stopped. It was necessary to rewrite the processing task itself. Further, since it is necessary for the processing task itself to process the drawing data of the screen to be displayed and the input / output processing with the operator, it is necessary to perform complicated processing.

However, according to this embodiment, since the processing task 1 and the input / output processing are independent of each other, the processing task 1 itself needs only to perform a simple processing with the component processing means 5 to display / operate components. You can use the input / output function of. Further, since the processing task 1 and the component processing means 5 are separated and the definition of the display / operation component is performed independently of the processing task 1, even when the specification of the display / operation is changed, the processing task 1 is not changed. The display and operation specifications can be changed, and since the display and operation components exist independently of the processing task 1, it can be easily used in another monitoring system, reducing the system development cost and development. It is also effective for shortening the period.

Example 2. FIG. 7 is an explanatory view showing a configuration example of display / operation parts in a supervisory control man-machine device according to another embodiment of the present invention. In the figure, 27 is a button part as a basic part having a basic display / operation function of notifying that the button is pressed as an input event, and 28 is a numerical part having an attribute internally displayed by an analog meter. It is an indicator part as a basic part with basic display and operation functions. Reference numeral 29 is an analog instrument part which is a composite part in which these are combined and the display value of the analog meter can be changed by the button. The device configuration in the second embodiment is similar to that in the first embodiment shown in FIG.

In this embodiment, it is possible to create a new display / operation component by combining a plurality of display / operation components having basic functions. That is, as shown in FIG. 7, a composite part in which parts having basic functions such as a button part 27 and an indicator part 28 are combined and a button attribute is set so that the display value of the indicator is changed when the button is pressed. By creating the analog instrument component 29, it is possible to easily create the analog instrument component 29.

In the conventional man-machine device for monitoring and control, it was necessary to create a process for analog display on the processing task 1 and to perform a process for input / output in the processing task 1. Further, it is necessary for the processing task 1 itself to manage various attributes such as display data and display color.

However, according to this embodiment, even when a display / operation component having a complicated function is created, it can be realized as a combination of display / operation components having a basic function, so that it is easily complicated. Various functions can be realized. Further, since the display / operation component exists independently of the processing task 1 and the component processing means 5, it is possible to easily divert it to other monitoring systems as well, thereby reducing the system development cost and the development period. Is also effective. Further, since the display / operation component itself holds and manages data such as numerical values and colors to be displayed as attributes, the processing task 1 does not need to manage the data. Further, since the shape of the display / operation component is arbitrary, the function of the display / operation component can be expressed by the shape thereof like the button component 27 shown in FIG.

Example 3. FIG. 8 is an explanatory view showing a configuration example of the display / operation parts in the supervisory control man-machine device according to still another embodiment of the present invention. In the figure, 30
Is a label part as a basic part having a basic display / operation function of displaying a character string. Reference numeral 31 has an additional display / operation function of inheriting the function of displaying the character string of the label part 30 and notifying the part as an input event when the part touches the part through the touch panel 12. A push button component as a successor component, and 32 is also the touch panel 12
It is a pull button part as an inherited part with a display / operation function added, which notifies the user of the fact as an input event when the finger is removed from. The device configuration in the third embodiment is similar to that in the first embodiment shown in FIG.

In this way, the functions are similar but different display /
When manufacturing the operation parts, it is necessary to separately create them in the conventional man-machine device for monitoring and control, and thus it is necessary to perform complicated processing. However, according to this embodiment, as shown in FIG. 8, the function of displaying a character string, which is a basic function of the label component 30, is notified when the finger touches it, or the finger is released. By adding the function of notifying that when the button is pressed, the push button part 31 and the pull button part 32 inheriting the function of the label for displaying the character string can be easily created. By inheriting the functions of the basic parts in this way, function-added parts having complicated functions can be easily created.

Example 4. FIG. 9 is an explanatory diagram showing a configuration example of the display / operation parts in the supervisory control man-machine device according to still another embodiment of the present invention. In the figure, 27
Is a button part as a basic part, 28 is an indicator part as a basic part, and 29 is an analog instrument part as a composite part. These are the same as those shown in FIG. 7 described in the second embodiment. Is equivalent. Also,
Reference numeral 33 is a target number setting component as a composite inheritance component to which another display / operation function of transmitting a set value is added while inheriting the function of the analog instrument component 29. The device configuration in the fourth embodiment is similar to that in the first embodiment shown in FIG.

In this embodiment, by adding another display / operation function to a composite part created by combining a plurality of display / operation parts having basic functions, the function of the composite part is inherited. However, it is possible to create a composite inheritance component with new functions. That is, as shown in FIG. 9, a button component 27 and an indicator component 28 are combined to create an analog instrument component 29. By adding a function of transmitting the set value to the processing task 1 when the button part is pressed, the value of the set value is processed when the button is operated while inheriting the function of the analog instrument part 29 that displays numerical values in analog. It is possible to form the target value setting component 33 having a new function of transmitting to the user.

As described above, by using the combination of display / functional parts and the feature of function inheritance, it is possible to easily form a composite inherited part having a more complicated function. Moreover, since this composite inheritance component exists independently of the processing task 1, it is easy to create, divert, and test the operation, and contributes to the improvement of productivity.

Example 5. FIG. 10 shows a display in a supervisory control man-machine device according to still another embodiment of the present invention.
It is explanatory drawing which shows operation | movement of an operation component. In the figure, 34
Is a button component as a display / operation component having a function of calling the plant state display as a display / operation function. In FIG. 10A, the button component 34 is an attribute, and the plant state can be displayed. In the case of having the operation condition, the button part 3 is shown in FIG.
The attributes held by 4 are respectively shown in the case where the operating condition in which the plant state can be displayed is changed to the operating condition in which the plant state cannot be displayed. The device configuration in the fifth embodiment is similar to that in the first embodiment shown in FIG.

The operation of the fifth embodiment will be described below with reference to FIG. In this embodiment, the button part 34 operates based on the operation condition that the button part 34 has as an attribute inside itself. The operator touches the button part 34 having the display / operation function for calling the display screen of the current state of the plant shown in FIG. 10A through the touch panel 12, and the input event is sent from the operator input / output unit 2. Suppose At this time, the parts processing means 5 checks the operation condition that the button part 34 has as one of the attributes. As a result, the plant status can be displayed.
Using the function of the button component 34, the processing task 1 is requested to display the plant status.

Here, it is assumed that the processing task 1 is in a state where the current plant state cannot be displayed. In that case, as shown in FIG. 10B, the processing task 1 requests the component processing means 5 to change the internal state of the button component 34 to a state in which the plant state cannot be displayed. As a result, the attribute of the button part 34 is changed from being able to display the plant state to being undisplayable, and even if an input event by the touch of the button part 34 is sent, the part processing means 5
Requests to display a message that the display is impossible instead of the plant status. After that, the state of the plant cannot be displayed until the processing task 1 changes the state of the button component 34 again.

As described above, by having the operation condition of the display / operation component as a changeable attribute inside the display / operation component, various operations can be performed on the same type of display / operation component. Further, by leaving the condition judgment to the display / operation component, the processing task 1 does not need to perform complicated processing, and since the attribute can be changed, the operation can be changed flexibly.

Example 6. FIG. 11 shows a display in a man-machine device for supervisory control according to still another embodiment of the present invention.
It is explanatory drawing which shows operation | movement of an operation component. In the figure, 35
Is a button part as a display operation part that has a function to call a message display part as a display / operation function.
As a function of event delivery, it has the function of delivering an event as a one-way request. Further, 36 is a message display component called by the component processing means 5 based on the input event from the button component 35. The device configuration in the sixth embodiment is similar to that in the first embodiment shown in FIG.

The operation of the sixth embodiment will be described below with reference to FIG. The button part 35 in this embodiment has a function of delivering an event, and particularly has a function of delivering the event as a one-way request. This one-way request does not require a response to the request even if a certain request is made to the display / operation means 3. For example, when sending a large number of commands such as a drawing request or a command with few errors. It is facing. This function is used with attributes that can dynamically change the destination and operating conditions. Here, it is assumed that the operator touches the button part 35 and an input event occurs. As a result, the component processing unit 5 is requested to call the message display component 36, and the component processing unit 5 checks the delivery conditions, the delivery destination, and the like to deliver this event, and displays the message on the message display component 36. Since this event delivery operates as a one-way request, the next event is accepted again without waiting time.

In the case of the conventional man-machine apparatus for monitoring and control, the processing task 1 itself needs to input and output events, and the processing of input / output control and event processing information must be managed. Was complicated. However, according to this embodiment, since the display / operation component is provided with the one-way request generation function as the event delivery function, the processing task 1 and the operator can receive and transmit the event without performing complicated processing. It will be possible.

Example 7. FIG. 12 shows a display in a man-machine device for supervisory control according to still another embodiment of the present invention.
It is explanatory drawing which shows operation | movement of an operation component. In the figure, 37
Is a button part as a display / operation part that has the function of acquiring the current time as a display / operation function.
It has the function of delivering events as round-trip requests as a function of event delivery. The device configuration in the seventh embodiment is similar to that in the first embodiment shown in FIG.

The operation of the seventh embodiment will be described below with reference to FIG. The button part 37 in this embodiment has a function of delivering an event, and particularly has a function of delivering the event as a round-trip request. This round-trip request requests a certain operation to the display / operation means 3 and waits for the result, which corresponds to the acquisition of the attribute of the display / operation part, and the button part 37 requests the acquisition of the current time. The time information returned is displayed. This function is used with attributes that can be changed dynamically such as destination and delivery conditions. Here, it is assumed that the operator touches the button part 37 and an input event occurs. As a result, the component processing means 5 is requested to obtain the current time by the round-trip request, and the component processing means 5 delivers the event by checking delivery conditions, delivery destinations, and the like. When the time information is obtained, the parts processing means 5 returns it to the button part 37 and displays the time information.
Since this event delivery operates as a round-trip request, the button component 37 enters a state of waiting for a reply from the component processing means 5, but the processing task 1 and the like can continue processing.

In the case of the conventional man-machine device for monitoring and control, the processing task 1 itself needs to perform input / output of events, and control of input / output and information of event processing and the like must be managed, so that processing is performed. Was complicated, and it was necessary to perform processing waiting for a reply. However, according to this embodiment, since the display / operation component is provided with the round-trip request delivery function as the event delivery function, the processing task 1 delivers the request without having a complicated procedure such as waiting for a reply. be able to.
