Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an apparatus for creating a background screen of a fixed part necessary for displaying plant status on a display device.

[Technical background of the invention and its problems] In order to monitor the status of a plant, the control system of each part of the plant is graphically displayed on a CI (T display).The graphic screen displays temperature, pressure, flow rate, etc. and a variable part representing variable data.

When creating a background screen that is a fixed part consisting of fixed parts such as piping and valves, conventionally there was only one screen memory for displaying on a CRT, and on that screen there was a screen to be created and a man-machine screen. Communication messages had to be displayed at the same time.

For this reason, the creation screen is limited to an area on the CRT screen excluding the area necessary for communication, and the resulting graphic screen is displayed in an area other than a part of the CRT screen.

Furthermore, when creating a graphic screen, the general procedure is to first set a large background, and then sequentially add pixels and lines of appropriate size to the background. However, in the case of the conventional device mentioned above, there is only one screen memory, so if another display is performed on the currently displayed screen, the previous display content will of course be erased, and the previous display content will be added. The intended movement of pixels, etc., was functionally impossible.

[Purpose of the Invention] An object of the present invention is to provide a background screen creation device for displaying plant status that uses the entire screen and can easily create a desired screen by freely moving images added to the screen. .

[Summary of the Invention] Therefore, the present invention provides three screens: one for man-machine communication, one for additional screen operations, and one for background screens that will be completed sequentially.
By preparing different types of screen memories, and synthesizing the contents of these screen memories using a screen memory synthesis device and displaying it on a display device, man-machine communication can be performed using the entire screen of one display device, and additional screens can be created. Then, superimpose them one after another and create screen memory 1 for completing the background screen.
By accumulating this, images can be freely displayed on the screen V'-
Oi JJI+.

The feature is that the desired background screen can be easily created by moving the screen.

[Embodiments of the invention] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a configuration diagram of a background screen creation device according to an embodiment of the present invention, where l is a CRT display device.

2 is a screen memory synthesis device, 3-5 are screen memories, 6-8
9 is a display input means, 9 is an input device, and 10 is a display input means. 12 is a memory, and 13 to 17 are transfer devices.

The screen memory 3 is used to display a screen for man-machine communication between the operator and this device.

The display input means 6 receives commands from the input devices 9) and controls the display contents of the screen memory 3. The display data used by the display input means 6 [is stored in MaMemo January 2 and can be obtained via the transfer means 15.

The screen memory 4 is used to display a graphic screen created and operated by the display input means 7. Display input means 7
specifically creates, corrects, and processes graphic pixels on one screen according to functions specified by the operator obtained through the input device 9 and the display input means 6. The screen data created by the display input means 7 is also stored in the memory 12 via the transfer means 16. Further, the data is returned from the memory 12 to the display input means 7.

When the creation of a partial graphic screen is completed on the display input device W7, the screen is transferred to the display input means 8 by the transfer means 14. The display input means 8 performs synthesis with the previous screen data and stores it in the one-screen memory 5.

Further, the data is transferred to the memory 12 via the transfer means 17 and stored therein.

Connected to the screen memories 3 and 4 are position specifying devices 10 and 11 for indicating the position of the driver 1 on the screen from the input device 9. This position specifying device is called a cross-haired crane, and is displayed in the shape of a cross on the screen, and its position can be moved using the keys of the input device 9.

That is, as shown in FIG. 2, there are four keys 9A, 9B, 9C, and 9D on the input device 9 for moving the cursor.
The cursor can be moved in the X-axis direction by pressing keys 9A and 9B, and in the y-axis direction by pressing keys 9C and 9D. Input from this cross cursor is input by pressing the execution key 9E on the input device 9 when the cross point is positioned at a desired position on the screen.

Further, on this input device 9, as shown in the figure, there are a skip key 9F, screen selection keys 9G, 9+1 . Alphabet keys 9I, numeric keys 9J, etc. are arranged.

The screen memo January 5.11 is displayed in a CRT display type combined state by the screen memory composition device 16.

Here, the screen displayed in the screen memory 3 is called screen l,
Similarly, the screen for the screen memory 4 is referred to as screen 5, and the screen for memory 5 is referred to as screen 1.

When creating a graphic screen with the above configuration, first press the screen ■ selection key 9G on the input device 9.

This signal is input to the display input means 6 and processed according to the flow shown in FIG. That is, the display input means 6 executes the flow shown in FIG. 3 in response to the input signal from the input device 9, and
The process proceeds from step 1101 to determine whether or not it is a screen selection key signal. If the signal is from the screen selection key, it is determined in 1102 whether the screen is ■ or ■.

If screen ■ is selected, the information on the screen is memorized in 1103, and the data to be output to the screen memory 3 is memorized in 1104.From January 2, the operation function menu is retrieved via the transfer means 15 and transferred to the screen memory 3. Output to. This state is shown in step 1 of screen I in FIG.

This operation function menu includes functions necessary for creating a graphic screen.

- Examples are 1 circle, rectangle, straight line, reduction/enlargement.

There are rotation, 1 color setting, 2 screen saving, initialization of storage area, 2 movement, copying, etc.

A square marker is displayed at the top of the menu to indicate that the function has been selected by inputting coordinates.

The operator moves the intersection point of the cross to the marker section of the function to be selected by pressing the cursor keys 9A to 9 on the input device 9 in FIG.
After setting the movement with D, press the execution key ]E.

When the execution button 91E on the input device 15 is pressed, the display input means 6 again executes the process shown in FIG. 3, and checks in 1101 whether the signal is a screen selection button signal. This is 1
Screen■ This is to enable processing only when selected. If the screen ■ is selected, control moves to 110B and checks whether the signal is from the execution key. If it is an execution key, the process moves to 1110; otherwise, the process moves to 1109.

1109 is a part that judges whether the skip button 9F has been pressed or not, and the other @ machines of number n go to exit 1115 without processing anything, and the processing by the display input means 6 is completed.

If the function is fixed at 1110, the screen position input is being used exclusively by another function. That is, it means that it is not a function selection. If the function is not fixed, the function conversion is 11 from the intersection coordinates of the cross and the crane obtained from screen memory 3.
It will be held in 11 parts. for example.

(X r +Y + ) is determined to be function 1, (Xl, Y2) is determined to be function 2, and so on. Once the selected function is determined in this way, control is transferred to the processing section corresponding to that function. In the example,
1112 when a function is selected, 1113 for function 2.
@Non moves to 1114 and performs function settings or actual processing. When the processing is completed, the process goes to part 1115.

When the function setting is completed in this way, the process moves on to specifically setting the function as a graphic screen. That is, since the graphic screen is created by the display input means 7 and the screen memory 4 as described above, the screen 1 selection key 911 on the input device 9 is pressed. Then, at 1105 in FIG. 3, the screen ■ selection is memorized, and at 1106, the screen memory 3 is cleared. Therefore, by this operation, the control is transferred to the display input means 7, and at the same time, the operation function menu on screen I is deleted.

The display input means 7 realizes the function specified by the display input means 6 as follows. That is, for example, if you want to draw a rectangular image on the screen, specify the desired coordinate Z+ on the screen with the crosshair cursor, and press the execution key 9 on the input device 9.
Press E. Next, a desired locus 1122 different from Z+ is set in the same manner. The coordinates of these two points Zs (Ztx, Z
+y), Zl (Z2x, 7.2V), the display input means 7 draws a straight line in the screen memory 4 in the following manner. (ZIX,
Zl v)→(Ztx, Z2v)−+(Z2x.

Zz v) → (Z 2'X, Z l v) → (Ztx
, Z+v). Step 2 on screen H in FIG. 4 shows this state.

Further, when the above processing is shown in flowchart 1, it becomes as shown in FIG. That is, when the execution key 9E is pressed while the screen ■ is selected, the signal is input from 1200, and it is checked at 1201 whether it is a processing request from another, but in this case, it is the signal from the execution key 9E. So, 120
Control moves to 2. If the signal is not from execution key 9E, nothing is done and the process goes to 1210 to end the process. When the signal comes from execution key 9E.

A branch process to the selected function processing unit is performed at 1203, and then to either 1204, 1205 or 1206, and the requested function process such as rectangle creation as described above is performed.

In this way, the function of the graphic screen is set using the display input means 6, control is transferred to the display input means 7, the selected function is converted into screen display data, and the specific function is executed again. If so, use the screen selection key to transfer control to screen ■, select the function, and repeat the control.

This state is shown in steps 3 and 4 in FIG. In step 3, screen I representing the function menu is displayed in double overlay on screen ■ created in step 2.
If the display brightness of the function menu is set high, there will be no problem in selecting functions by scrolling to the cross. Of course, it is also possible to not display the screen (■) at this time. In step 4, screen ■ is selected and a circular image is added to the previously created screen.

When creating this circular image on the screen, set a section in which to rotate the pixels. Next, you need to set the rotation angle, which can be set anywhere on the screen. Three coordinate points are required for rotation, and each is set with a circle to the cross, and they are Po.

Let them be PI and P2. The rotation angle is an angle surrounded by P+POP2. Note that the rotation direction is around the hour H1. When the angle and section are aligned, rotation is performed in the specified angle training direction.

In this way, when step 4 of creating the graphic screen is completed, the screen selection key 9G of the input device 9 is pressed to select the screen.
Select Screen I. This state is step 5 in Figure 4.
corresponds to Here, from the operation function menu, specify data saving on screen ①.

The display input means 6 is connected to the display input means 7 via the transfer means 10.
A command is given to save the screen memory 4. The display input means 7 reads the screen memory 4 and transfers the read contents of the screen memory 4 to the display input means 8 via the transfer means 14. When the transfer is completed, the contents of the screen memory 4 are cleared and returned to the initial state.

The processing performed by the display input means 7 will be explained with reference to FIG. 5. A save command issued from the display input means 6 is guided to 1200, determined to be a request from another at 1201, and branched for each requested function. is performed in 1207, and any one of the functional processing units 1208...120! '18 branches and the request contents are processed.

On the other hand, the 1 display input means 8 stores the screen data sent from the display input means 7 in a temporary storage buffer a at 1301, as shown in FIG. When the storage is completed, the contents of the screen memory 5, which is the current completed screen, are read in 1302 and stored in another buffer b. Further, the buffer a and the buffer b are combined, and the result is put into the buffer C and simultaneously outputted to the screen memory 5 again.

Further, the contents of the buffer C are stored and saved in the memory 12 via the transfer means 17.

Step 6 in FIG. 4 shows the state at this point. The screen memory 5 updated by the display input means 8 becomes the background of the screen in the next screen creation step, and serves as a reference for the position and layout of the entire screen with respect to the screen H.

In this way, the functions are shown on the screen i and created on one screen ■, and the created screens are sequentially saved on the screen Ill to create the desired graphic screen.

According to this method, the screen on which the graphic screen can be processed is limited to the screen ■, and there is no need to worry about destroying the screen ■. It has the feature of being able to create graphic screens while considering colors, etc.

Next, an example of displaying plan 1 to status using this graphic screen will be described.

In general, Plan 1 - Manual input is roughly divided into two types: analog input and on/off type, and from the perspective of alarm, limit value deviation (there are two types: upper limit deviation and lower limit deviation). ) and there is an error in the input point. There are two types of abnormal states: the contact input is in the same state as the limit value (indicated as on or off), or the on or off state cannot be detected due to other reasons.

Setting these plant states to the graphic screen is created using the same procedure as creating the graphic screen, but the created information is stored in a different location from the graphic screen data. The specific steps for creating it are shown below.

Screen I is selected using screen selection on the input device 9. Then, C
An operation function menu as shown in FIG. 7 is displayed on the RTI screen (screen memory 3). Therefore, select the "Analog type plant entry setting" or "Contact type plant input setting" using the crosshair cursor keys.When these functions are requested, the function is declared fixed and continues until it is released. When selected, the display input means 6 sends a message (POINT) prompting the input of a plant input point number to the message output canister of the screen memory 3, moves the cursor to the plan 1 to input point number coordinates, and waits for input. Inputs to Caniglia are input from the alphabet keyboard and numeric keypad of the input device 9.Completion of input is confirmed by pressing the execution key 9E.The display input means 6 displays the plant input point input from the plant input point number coordinates. is read and set in the plant input point number area 122 of the memory heel shown in FIG. 8. Graphic data is stored in the memory area 121. When the setting of the plant input point number is completed, the display input means 6 A message prompting you to input the location of the image whose color changes depending on the state (LOC)
ATION-1) is sent to the screen memory 3.

In order to set coordinates on the graphic screen, switch from screen I to screen ■ using the screen selection key on the input device 9.

After that, set the red crane to the cross as the command image to change the color, and press the execution key 9E.

The coordinates input by the display input means 7 are sent to the display input means 6 by the transfer means I3 and set in one display coordinate area 123.

When you return the screen from screen ■ to screen I using the double-sided selection key,
The display input means 6 sends a message (VALtlELOCATION) to the message output canister of the screen memory 3 to prompt the setting of coordinates for displaying plant input values.

The setting procedure is exactly the same as inputting an image whose color changes depending on the plant status described above. The input coordinates are set in the display coordinate area 124. Note that this function may not be necessary, so in such a case, if you press the skip key 9F on the input device 9 when the message is displayed, "None" will be set in the display coordinate area 124. .

Next, the display input means 6 sends a message (NORMAL C0LOR) to the screen memory 3 to prompt the display color in normal conditions. To specify a color, specify the position of the color sample displayed as part of the operation display menu in the screen memory 3', J:, as shown in FIG. It is specified by pressing key 9E. The coordinate data input to the display input means 6 is converted into a color code and set in the normal display color area 125 in FIG.

Next, a message prompting you to input the abnormal display color (ABNOR
MAL C0LOR) is sent from the display input means 6 to the screen memory 3. The setting method is exactly the same as inputting the normal display color, and the color code is set in the abnormal display color area 126.

Next, a message (III ALARM
C0LOR) is sent from the display input means 6 to the message output canister of the screen memory 3. This color setting method is also set in the normal display color area 127.

Next, a message (LOli ALARM COI, OR) prompting for a display input when the analog input lower limit value is exceeded is sent from the display input means 6 to the screen memory 3. The color setting method is also the same as inputting the normal display color. The color code is set in the alarm display color area 128. If the displayed color is the same as that when the upper limit is exceeded, the skip key 9F can be pressed instead of the color setting operation.

In this case, the 1 display input means 6 sets the same color as the alarm display color area 127 in the alarm display color area 128.

When this setting operation is completed and a series of operations are completed, the display input means 6 sends a completion message (E'ND OF ASSIGN) to the message output canister of the screen memory 3, and requests the next different function. possible.

In this way, there are three types of image memory 3. /1.5 is prepared, the image memory 3 is used to perform function settings, the image memory 4 is used to perform screen creation operations, the created screens are sequentially stored in the screen memory 5, and a total screen is created and saved. By doing so, it is possible to freely change, modify, add, delete, etc. the images that are sequentially created without causing any hindrance to the total screen to create a desired shape.

In addition, conventionally, the entire area of the C1117 screen could not be used as a graphic screen area, but in this embodiment, by providing two screen memories, one for man-machine communication and one for creating one screen, the entire screen can be used for man-machine communication. This enables advanced communication.

Furthermore, the screen creation time can be shortened by increasing the sophistication of man-machine communication and removing constraints in the screen creation process. Moreover, it becomes possible to easily deal with partial changes.

In the above embodiment, it has been explained that the contents of the screen memories 3, 4.5 are synthesized by the screen memory composition device 2 and displayed simultaneously on the CRT display device Wl. It goes without saying that the images can be displayed freely by switching them as appropriate.

[Effects of the Invention] As described above, according to the present invention, three types of screen memory are provided, one for man-machine communication, one for creating individual screens, and a total screen for storing and storing the created screens. Since it is displayed on the device, it is possible to create a graphic screen using the entire display screen and also add images.

A device for creating a background screen for plant status display with extremely good operability and easy modification and deletion can be obtained.
