Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an information display method for guide information, etc., and in particular, in a process monitoring device used in a plant factory, guide information necessary for an operator is displayed for process monitoring. The present invention relates to a method for displaying information such as guide information on a display device, etc., which can be displayed in a superimposed manner on a monitoring screen.

[Prior art]

In a conventional process monitoring device using a CRT display device, an operator performs a predetermined operation to control a process in a certain plant, and guide information necessary for this purpose is displayed on the CRT screen.

In such a case, if the guide information is displayed using the entire area of the CRT screen, the process monitoring screen, which must be constantly monitored, cannot be observed.
Conventionally, a method has been adopted in which a part of the M area of the screen is reserved as an area exclusively for displaying Yosaki guide information.

However, with this method, the process monitoring screen is narrowed, which not only reduces the display capacity of process monitoring information, but also limits the dedicated display area for guide information. It is necessary to simplify the expression by encoding it using symbols and symbols.

[Problem that the invention seeks to solve]

If the guide information is coded in this way, the operator will need to become familiar with the code, and if it is handled by an inexperienced person, an instruction manual such as an "instruction manual" should be prepared. It becomes necessary to keep it. Also,
In such a case, it takes a considerable amount of time to operate the device while referring to the manual, which poses a problem when the device must be operated within a short period of time.

As a method to compensate for this drawback, it is possible to display the guide information in text instead of coding it and abstracting it, but in this case, although the troublesomeness of reading the aforementioned manual is alleviated, Since the area dedicated to displaying guide information is limited, it is extremely difficult to express it accurately in short sentences without causing misunderstandings.

Further, it is usually impossible to secure enough space on the screen to display text.

[Purpose of the invention]

The present invention has been made in view of the problems of the prior art, and it solves these problems and allows CR7 to be used without setting a dedicated display area for guide information. The purpose of the present invention is to provide a method for displaying information such as guide information that allows the use of the entire display screen to observe temporary display information such as guide information as well as regular display information such as process monitoring information. .

[Means for solving problems, etc.]

The means of the present invention taken to solve the above-mentioned problems and achieve the object of the present invention is to provide a display device capable of displaying at least two types of display information in a superimposed manner. a first screen memory in which display information to be displayed is stored, and a second screen memory in which display information to be constantly displayed is stored;
The part other than the temporary display information part of the first display screen memory is made transparent and is displayed superimposed on the display information of the second display screen memory.

[Effect]

By the way, recent CRT display devices have become more sophisticated by stacking multiple display screens and displaying them on a single CRT screen, or by using a part of the top display screen as a window. It has been proposed to have a so-called window function that allows you to look into the lower display screen.

The present invention relates to a display device that can superimpose such two types of display information.

In the process of monitoring processes, etc., the superimposed screen should be used as guide information, the superimposed screen should be used as monitoring information, and the other parts of the guide information should be displayed as transparent. This allows monitoring information to be observed at the same time through this transparent part.

Moreover, the display can be made compatible with the screen,
A special display area for guide information is no longer necessary, and it becomes possible to view both monitoring information and guide information.

Therefore, the entire screen area, which is the same as the process monitoring screen area, can be used for displaying guide information, and there is almost no restriction on the number of displayed characters, for example, and a greater degree of freedom can be achieved in displaying guide information. Furthermore, observation of the process monitoring information is hardly hindered even when the guide information is displayed, and the continuity of the process monitoring screen is maintained, causing less discomfort to the operator, thereby reducing operator fatigue.

[Embodiments of the invention]

Hereinafter, one embodiment to which the present invention is applied will be described in detail with reference to the drawings.

FIG. 1 is a diagram illustrating the principle of an embodiment of the present invention.

In the figure, 1 is a screen to be displayed by a first screen memory corresponding to one screen displaying guide information Ga in a CRT display device capable of displaying at least two types of information in a superimposed manner. This is a virtually set display plane (hereinafter referred to as the first display plane), and 2 is the screen that should be displayed by the second screen memory corresponding to 1 screen that displays information P for monitoring the process of the plant. The screen is a virtually set display surface (hereinafter referred to as a second display plane), and is arranged behind the first display plane 1 as a superimposed screen.

Here, the display information on the first display plane 11 and the second display plane 2 corresponds to the size of the display screen of the display, and is superimposed on the display screen of the display as one screen of information. In the first display plane 1, areas other than the display information portion are treated as transparent and superimposed.

Now, for example, if an operation error occurs and it becomes necessary to display guide information, an example of the guide information Ga is ``The input data exceeds the upper limit.'' i pieces of information are stored on the screen memory corresponding to the second display plane 2, and are displayed superimposed on the display information on the screen memory corresponding to the second display plane 2 for a relatively short period of time.

FIG. 2 shows a CRT display screen when information on the first display plane 1 and the second display plane 2 is superimposed, and the first display plane 1 is transparent. Therefore, observation of the constantly displayed process monitoring information P is not completely obstructed.

This guide information Ga is transferred to the CRT using appropriate known means.
It is possible to erase the guide information Ga from the display screen. For example, such guide information Ga may be erased automatically after a predetermined period of time has elapsed, or it may be erased by an operator's key operation.

FIG. 3(a), FIG. 3(b), and FIG. 3(c) are principle explanatory diagrams of other embodiments of the present invention, in which a background color is provided on the first display plane 1. It is.

That is, the character information C in the guide information Ga can be clearly observed as shown in FIG. 3(C) due to the background color area H shown by the hatched area surrounded by dotted lines.

This back background area H provided on the first display plane 1 is preferably a colored part, for example, light red or light green. In this case, the process monitoring information IP on the second display plane 2 is Although it is difficult to observe clearly, if the character information C of the guide information Ga is expressed in white characters, for example, it will be displayed more clearly in contrast with the background color, and it can be read in a short time. becomes possible.

In this way, if it becomes easier to read the guide information Ga and thereby shortens the time required to recognize the information, it becomes possible to reduce the time during which the guide information Ga obstructs observation of the process monitoring information P, which is advantageous. It is something.

In such a case, it is possible to limit the display time to a certain period of time or to display the guide information Ga blinking at short time intervals. Furthermore, the range of the background color area is preferably set to such an extent that only a portion of the monitoring information can be seen, without making it as large as possible within the range of one screen.

In addition, FIG. 3(C) is observed by superimposing the information of the first display plane l shown in FIG. 3(a) and the second display plane 2 shown in FIG. 3(b). CRT that can be
This shows the display screen.

FIG. 4(a), FIG. 4(b), and FIG. 4(C) are principle explanatory diagrams of other embodiments of the present invention, and the differences from the embodiment of FIG. 1 are as follows. The character information C on the first display plane 1 shown in FIG. 4(a) is expressed in bold and colored characters. By making the characters colored in uppercase in this way, the CRT screen can be displayed as shown in Figure 4(c).
As shown in Figure 2, it is possible to clearly observe guide information.

By the way, when displaying the background color or color as described above,
A color display device will be used, in which one pixel or each coordinate position is red (hereinafter referred to as R).

Each data corresponds to the three primary colors of green (G), blue (B), and 4 bits of flicker (F).
A combination of the three primary colors G and H, white and red.

Green, blue, cyan, magenta, yellow, and black are expressed.

Here, black is a state in which the phosphor of the CRT is not emitting light, and the background color of the CRT is visible. On the other hand, flicker information is information indicating the presence or absence of flicker. If flicker is present, the dot on the screen periodically switches between the display color specified by R, G, and B and black. It is something that can be done. Note that this flicker serves to alert those viewing the CRT display.

Next, taking such a color display device as an example, the first display plane 1 processes other than the display information as transparent, the screens are overlapped, and the second display plane 2 is placed on the lower side. The process of displaying this information along with the lower screen information will be explained.

By the way, such a display device displays these two screens by using the screen information stored in the first refresh memory as the upper screen information and the screen information stored in the second refresh memory as the lower screen information. In the case of overlapping display, the flicker information corresponding to the position where there is no display information in the screen information of the first refresh memory is referred to, and if this flicker information is in one predetermined state, the second refresh is performed. This can be achieved by prohibiting the display of display information at a corresponding position in the screen information of the memory.

In this way, using flicker information at a position where there is no display information, that is, flicker information for black display,
There is that flicker. Without this, it becomes possible to superimpose two screens, transparent superimposition processing, window frame processing, etc. with simple processing without increasing the refresh memory capacity.

Here, to explain the principle, flicker designation for a dot with a designated display color is meaningful by making the display color blink. In this case, a predetermined display color and black are alternately displayed, resulting in a blinking state. However, in the case of so-called black display without designation of a display color, designation of flicker results in switching between black and black, and the flicker itself has no meaning and no blinking state occurs.

On the other hand, when overlapping the screen information of two display screens, the areas where there is no display information in the screen information of the upper screen,
That is, in the black display area without pictures, the display information of the lower screen is displayed, and the two display screens overlap. When performing transparency processing or window display, the transparent black display area displays the lower display information, and the window frame and black character display information that serves as guide information are displayed in the black display area that is transparent. This means that the display area that corresponds to the part may be configured not to display the display information on the lower side. Further, in the case of color display, if display information is on the upper side, it is displayed as is, and display information on the lower side is not displayed.

Therefore, regarding the display information in the upper screen information that serves as guide information, for the black display area where there is no display information, flicker information, which is meaningless information in black display, is used to improve the lower display. This can be used differently for information that means displaying information (that is, compatible with transparent processing) and information that means not displaying the lower display information (corresponding to displaying black guide characters or frame processing). If you use it, you will be able to do the above separation.

In other words, by effectively utilizing this flicker information,
The upper screen can be made transparent or opaque.

As a result, it is possible to overlap two pieces of screen information or frame them on the lower screen without increasing refresh memory.

FIG. 5 is a block diagram of a specific circuit configuration of the refresh memory portion of the display device in each embodiment when such a display device that performs transparent superimposition processing using flicker information i is applied. It is.

In the figure, 1a is the first refresh memory, 2a
is the second refresh memory.

These first. Second refresh memory la.

2a are accessed by a dot address signal sent to the dot address signal line 3 from a display control unit (not shown), and are assigned R, G, and B under predetermined conditions.
The 3-bit display information of R output signal line 5. G output signal v
It is output to the A6 and B output signal lines 7.

Here, the first. Second glue fresh memory la.

2a have the same configuration, and the first refresh memory 1a has a screen memory l1a (hereinafter referred to as memory 11a) that stores screen information for one screen corresponding to the first display plane 1, and flicker priority. It includes a determination section 12a and a display information output section 13a. Further, the second refresh memory 2a has one memory corresponding to the second display plane 2.
It includes a screen memory llb (hereinafter referred to as memory 11b) that stores screen information for a screen, a flicker/priority determination section 12b, and a display information output section 13b.

Each memory lla, llb stores R, G, H display information and F flicker information corresponding to each dot position on the screen.
Bit display data is stored as screen information. These memories lla and Ilb are connected to the dot address signal line 3.
The 4-bit display data of the R, G, B display information and the F flicker information at that position are addressed by the dot address signal sent to the display information 16a, 16.
b.

The flicker information is read out as flicker information 17a, 17b and sent to the flicker/priority determination sections 12a', 12b, and at the same time, the 3-bit R, G, B display information 16a, 16b is sent to the display information output section 13a, respectively.

13b.

Here, the flicker/priority determination units 12a and 12b respectively display display information 16a and 16b, flicker information 17a,
In addition to information on each of the four bits and nodes 17b, a flicker timing signal is received from the flicker timing signal line 4. Then, the flicker/priority determining unit 12a or 12b determines whether at least one bit of the three bits of R, G, and H display information 16a, 16b is 1''. When any bit is "1", the value of the flicker information 17 (value of F) is referred to, and if this is "1" (flicker present), the flicker signal is set in response to the flicker timing signal. 18a or 1
8b, and inhibits the output of priority output signals 15a and 15b, respectively. Note that when at least one bit is "1", it means that a display color is specified.

Now, referring to the value of the flicker information 17 (value of F), if it is "1" (flicker present) and no flicker timing signal is received, or if the flicker information 17
When the value of is "0" (no flicker), the flicker/priority determination units 12a and 12b respectively prohibit the output of the flicker signal 18a or 18b and output the priority output signal 15.
Output a or 15b. Further, when the flicker information 17 value (F value) is 1'' (flicker present) and a flicker timing signal is received, the flicker signal 18a or 18b is output, and the priority output signal 1
Prohibits output of 5a or 15b.・On the other hand, R, G, B
3-bit display information 16a.

It is determined whether at least one bit of bits 16b is 1'', and all bits are set to 0.
'', the flicker signal 18a or 18b is not generated regardless of the presence or absence of the flicker timing signal.

At this time, referring to the value of flicker information 17 (value of F),
When this is "1", priority output signals 15a, 15b
is output, and when this is “O”, the priority output signal 15
a.

15b are prohibited.

Here, the generated flicker signal 18a or 18b is transmitted to the display information output section 13a of each refresh memory,
13b, while the priority output signal 15a is sent to the second
The information is sent to the display information output section 13b of the refresh memory 2a.

Here, the priority output signal is a signal that prohibits the output of display information of the lower refresh memory (corresponding to the lower screen). The refresh memory 2a becomes the lower order, and the priority output signal 15a prohibits the output of its display information. Note that the first refresh memory 1a
is for storing screen information that becomes the upper screen when superimposed, and is higher-order with respect to the second refresh memory 2a. Therefore, the priority output signal 15b of the second refresh memory 2a, if there is a lower refresh memory than this, is sent to the lower refresh memory and prohibits output of display information of that refresh memory.

Further, the flicker signal is for displaying black in accordance with the flicker timing, and inhibits the output signal of the refresh memory.

As a result of the above, the 3-bit display information 16a of R, G, and B
The display information output section 13a of the first refresh memory 1a that receives the flicker signal 18a outputs the 3-bit display information 16a of R, G, and H to the R output signal line 5. G output signal line 6 and B output signal line 7
Output to. Then, a priority output signal 15a is sent to the second refresh memory 2a. Furthermore, when the flicker signal 18a is received, the output of the display information output section 13a is prohibited.

On the other hand, the priority output signal 1 of the first refresh memory 1a
The display information output unit 13b of the second refresh memory 2a, which receives the input signal 5a via the priority output input line 14b, is prohibited from outputting the 3-bit display information 16b of RlG and B read from the memory llb. In addition, the flicker signal 18b
When received, the output of the display information output section 13b is prohibited.

By the way, if a refresh memory exists as a higher-order memory than the first refresh memory 1a (not shown), the display information output section 13a of the first refresh memory 1a will give priority to the same priority output signal. When received via the output input line 14a, R and G sent from the memory lla.

The 3-bit display information 16a of B will not be output. In addition, if there is a refresh memory (not shown) as a memory lower than the second refresh memory 2a, the priority output signal 15b is sent to the display information output section of the refresh memory to display the display information of the refresh memory. Output of information is prohibited.

Next, the overall operation in the case of superposition processing, including transparent processing, blinking processing, etc., will be explained.The dot address signal sent to the dot address signal line 3 causes the first.
When the second refresh memory la, 2a is addressed, each memory 11a.

Display information 16a and 16b are output from display information 11b, and when at least one of the three bits R, a, and B of display information 16a is "1", priority signal 15a is output from display information output section 13a to second refresh memory 2a. is output, and the output of the display information 16b of the second refresh memory 2a is suppressed.

Then, 3-bit display information 16a of R, G, and H is transmitted from the display information output section 13a to the R output signal line 5. The signal is output to the G output signal line 6 and the B output signal line 7, and display processing is performed.

As a result, only the display information of the screen information of the first refresh memory 1a, that is, only the display information of the upper screen is displayed on the display screen, and at this time, the display information of the lower screen is not displayed. In this case, the first
flicker signal 18a in the refresh memory 1a of
It is assumed that this has not occurred.

Here, if this flicker signal 18a is generated,
That is, when the read flicker information 17a is "1" and coincides with the flicker timing, the flicker signal 18a is generated in accordance with the flicker timing, and the display information output section 13a receives this. , the output of the display information output section 13a is prohibited, and the display information on the upper screen is not displayed, but the display information on the lower screen is displayed.

That is, at the same time, the output of the priority output signal 15a of the first glue fresh memory 1a is prohibited and is not output to the second glue fresh memory 2a, so that the display information 16b of the second glue fresh memory 2a is displayed on the lower screen. R output signal line 5 from display information output section 13b as display information
．． It is output to the G output signal line 6 and the B output signal line 7. As a result, only the display information of the lower screen is displayed on the display screen.

Note that, at this time, it is assumed that the flicker signal 18b is not generated in the second glue fresh memory 2a.

On the other hand, the display information corresponding to the upper screen is read out in this way, and the display information 16a is read out from each memory 11a, llb.
, 16b are output and the 3 of R, G, and B of the display information 16a are output.
When all the bits are "0" and the flicker information is "O", the display information on the lower screen is displayed on the display screen. That is, the outputs of the 3-bit display information 16a of R, G, and B from the display information output section 13a are all "0", and furthermore, the output of the priority output signal 15a is not generated. Therefore, regardless of the flicker timing, the display information 16 read from the second refresh memory 2
b is the R output signal vA5.b from the display information output section 13b. It will be output to the G output signal line 6 and the B output signal line 7.

As a result, the display information on the lower screen will be displayed on the display screen.

In this case as well, it is assumed that the flicker signal 18b is not generated in the second refresh memory 2a.

Here, display information 16a,
16b is output, and when all three bits of R2O and B of the display information 16a are "0" and the flicker information is "1", the display information on the lower screen is not displayed on the display screen, and the screen is , the display is simply black. That is, the outputs of the 3-bit display information 16a of R, G, and B are all O'', and the priority output signal 15a is output regardless of the flicker timing. Therefore, the display information 16b read from the second refresh memory 2a is transmitted from the display information output section 13b to the R output signal line 5.0 and the output section line 6.
, B output signal line 7. the result,
Only the display information on the upper screen will be displayed on the display screen. At this time, the display information on the upper screen is all "o", so the screen is displayed in black.

Therefore, if the area where this display information is all "0" and the flicker information is "1" is set to store predetermined character information as guide information, the area other than the location of this character information will be stored in the second pasteboard. This means that screen information in the memory 2a can be displayed.

That is, the area where the flicker information is "1" is the guide information, and the area where the flicker information is "θ" is the display area for the monitoring information of the lower picture. Also, at this time, all the data in the display information 16b of the second refresh memory 2a is “
If it is θ'', the display on the lower screen will also be black, and the screen will be displayed in black.

On the other hand, in an area where at least one bit of display information on the upper screen is "1" and all other display information is "0", if the flicker information is 0", then the area is the display area for the lower picture.As a result, the upper and lower two screens can be displayed overlappingly.

By setting the black flicker information to a predetermined value in this manner, it becomes possible to freely set the overlapping process for transparent display.

Incidentally, when the above-described processing of the flicker/priority determination unit 12a and screen display are compared and shown as a table, the result is as shown in FIG.

Here, the memory flb of the second refresh memory 2a
The flicker information stored in the screen may be determined depending on the refresh memory installed below it, and if the lower screen is to be displayed black, this may be set to "1".
Furthermore, the second refresh memory 2a does not need to store such flicker information.

As described above, when simply overlapping the upper screen and the lower screen, each bit of the display information in the first refresh memory la (upper screen) is all "θ", and the corresponding flicker information is If you want to display black characters on the upper screen, set each bit of display information at the necessary location corresponding to the guide information position of the screen information in the first refresh memory 1a. All O",
In addition, it is sufficient to set the flicker information to 1''.

Also, regarding the background color, the first glue fresh memory 1a
Color information corresponding to a predetermined area of memory lla may be set.

Furthermore, as in the specific example shown in FIG. 5, when at least one of the bits of the display information is "l", the flicker information is set to "1" to distinguish between the upper screen and the lower screen. They can also be displayed alternately.

As explained above, in the specific example of FIG.
Although it is assumed that there is no flicker when the value is '0', it may be set to '1' or '0'.

Further, "1" and "0" of each bit of display information are the same, and the flicker timing in the table of FIG. 6 is also the same.

In the specific example, flicker information only needs to be present on the upper screen, and this flicker information does not need to be stored on the memory in correspondence with the display information. For example, in the case of a window, the information may be stored in the form of flickering range information.

Further, the display information output section may be a simple gate circuit,
It may be configured integrally with the flicker/priority determination section. Further, the flicker/priority determination unit of the first glue fresh memory 1a sends out a priority output signal as a signal for prohibiting the display of the display information at the corresponding position in the screen information of the second glue fresh memory 2a, but it is prohibited. The signal is not limited to this type of signal.

Furthermore, these may be processed and realized by a program.

In the specific example of FIG. 5, the refresh memory is exemplified to store screen information corresponding to display information corresponding to dots, but it goes without saying that this may also be display information corresponding to coordinates. It is.

Further, although an example of color display is given, it goes without saying that so-called black and white display may also be used.

The above explanation has focused on the process of making a predetermined area of the upper first display plane transparent, but the process of making it transparent is not limited to the circuit shown in FIG. For example, it is possible to separately provide a memory corresponding to a screen that specifies transparency or the like.

In the embodiments, the explanation focuses on monitoring processes in plants, etc., but the present invention is not limited to such monitoring, and the present invention is not limited to such monitoring. This method can be applied to displaying two types of information on one screen, such as information and regular display.

〔Effect of the invention〕

According to the present invention, in a display device capable of displaying at least two types of display information superimposed on each other, a first display device in which temporary display information such as guide information is stored.
screen memory, and a second screen memory in which display information to be constantly displayed is stored; Since the display is superimposed on the information in the display screen memory, when monitoring processes etc.,
The same full screen area as the process monitoring screen area is available for displaying guide information.

As a result, the degree of freedom in displaying guide information can be increased, for example, with almost no restrictions on the number of displayed characters. Furthermore, observation of the process monitoring information is hardly hindered even when the guide information is displayed, so that the continuity of the process monitoring screen is maintained and the operator feels less discomfort, thereby reducing operator fatigue.

Furthermore, displaying, erasing, and redisplaying guide information after erasing can be performed completely independently of the display program, making it easy to create and execute programs.
