Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant monitoring device that displays a monitoring screen on a display device for monitoring plant conditions.

(Prior Art) In recent years, as plants have become larger and equipment configurations have become more complex, the number of items that operators must monitor has increased significantly in various plants.

Therefore, in order to reduce the burden of monitoring work on operators and improve work efficiency, plant monitoring devices that can monitor the status of each part of the plant on a single monitoring screen have been put into practical use.

In such a plant monitoring device, the monitoring screen display device that displays the monitoring screen is used to monitor when the state of the plant changes, for example from the start of plant startup to normal operation, or from one normal operation to the completion of shutdown. During the driving process, the displayed monitoring screen can be changed as desired.

Generally, the display content of a monitoring screen consists of fixed information and variable information. The former fixed information is information on a fixed screen that shows the appearance and outline of Plan 1~ and instrumentation, and makes the plant shape etc. similar to the real thing so that it can be easily recognized.
The display colors are unified according to the component devices. The latter variable information is variable screen information representing the current state of the plant, and is composed of numerical values, characters, par charts, patterns, and the like. In addition, display colors and patterns are selected so that each monitoring target can be distinguished.

The operator then judges the situation while looking at the plant status quantities and plant status information displayed on the monitoring screen.
This allows the plant status to be monitored.

(Problem to be Solved by the Invention) However, conventionally, when the amount of plant information displayed on one monitoring screen is very large, the size of the characters displaying plant state quantities on the monitoring screen becomes small, or the characters are Because of the close proximity of the plant, it has become difficult to recognize current plant state quantities, alarm information, and abnormality information.

In addition, if the display characters that display plant state quantities are very small, even if the plant state quantities change and the display color of the display characters changes, the change will not be recognized, causing the operator to overlook such state changes. There is also a risk that this may occur.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems and provide a plant monitoring device that can clearly recognize changes in plant state quantities.

Further, the operation of the monitoring screen variable section display means 9 is controlled by the display means 6.
This is repeated in response to the display cycle.

FIG. 2(a) shows an example of monitoring screen information stored in the monitoring screen storage device 5. FIG.

The monitoring screen information includes n pieces of monitoring screen display information DSI to DS.
Consisting of n, each monitoring screen display information O3L~DS
n is monitoring screen identification information 1D for identifying the monitoring screen displayed and output based on the screen display information DSL to DSn.
, name information N that represents the name given to the monitoring screen, fixed partial information display data F that represents the appearance of the plant on the monitoring screen, and variable numbers such as numerical display of plant data to be displayed on the monitoring screen. It consists of partial display information data FL.

The variable portion display information data FL is composed of display data information DTI to DTm representing the contents of each variable information to be displayed on the monitoring screen, as shown in FIG. 2(b).

In addition, each display data information DTI to DTm is, as shown in FIG. 3(a), its display data information DT (
DTl-DTm), a plant data number PID representing the corresponding plant data, a display position PST representing the screen position where the plant data is displayed, display presence/absence information AVL representing whether or not to display the plant data,
It consists of data display information DPI to DPi that represents the display form of the plant data in each of the signal sections set by dividing the signal range that the plant data can take.

Here, the content of the display presence/absence information AVL is rewritten by the plant automation operation means 4.

Then, each data display information DP (DPI to DP
i), as shown in Figure (b), display priority PR1 indicating the priority for displaying the plant data, section range information ARE indicating the upper and lower limit values of the corresponding section, and displaying the plant data. Character display information CHR that indicates the display color of numbers and their font size, pattern display presence information that indicates whether or not to display a pattern to be added to the numbers displaying plant data for emphasis, and the pattern when displaying the pattern. Pattern display information PTR1 indicating the display color and, for example, additional information display presence/absence information indicating whether plant data is within a signal range to be determined as an alarm occurrence and disallowance information to display that fact is displayed. It consists of additional information display information ADT consisting of data representing the content of the information.

For example, as shown in Figure 4(a), considering the flow rate of pump P in water supply system A, the possible values of the flow rate of pump P vary from 0 to 150 as shown in Figure 5. , the signal range from 0 to less than 50 is in section 1.

A signal range of 50 or more and less than 100 is set in section 2, and a signal range of 100 or more and less than 150 is set in section 3. As the signal range changes from section 1 to section 3, the alarm state becomes more serious.

In this case, the data display information DP of this pump P is the sixth
Formed as shown in the figure.

That is, for the flow rate of this pump P, the plant data number PID is set to rlooJ, the coordinate position of the display position PST is set to (300, 300), and three data display information DPI to DP3 are set. has been done.

In data display information DPI, display priority PRI is rlo
For OJ, the character size is set to r16 x 8J, the character display color is set to "white", the pattern display is set to "no display", and the additional information is set to "no display".

In the data display information DP2, the display priority PRI is "50".
", the character size is set to "r24x12", the character display color is set to "black", the pattern display is set to display and its display color is "yellow", and the additional information is set to not display.

In data display information DP3, display priority PRI is "5"
At this time, the font size is set to r36XIJ, the font display color is set to "black", and the pattern display is set to "red" if it is displayed, and at this time, it is in an alarm state and an indication to that effect is set. It is set to display the character string "Large flow rate" as additional information.

In this way, as the degree of danger of the plant data increases, the display attributes are changed so that the recognizability of the display character string increases, and the display data information is formed so that the display priority increases. There is.

Further, information other than the display presence/absence information AVL whose contents are rewritten by the plan 1-automated operation means 4 is set in advance and stored in the monitoring screen storage device 5.

With the above configuration, the plant data input means 1 inputs the plant data output from the plant 2 at a predetermined period and stores it in the plant data storage table 3, and the plant automation operation means 4 inputs the plant data output from the plant 2 at a predetermined period and stores it in the plant data storage table 3. The automated operation of the plant 2 is performed based on the memory contents of step 3, and the monitoring screen display information DSI to DSI stored in the monitoring screen storage device 5 is displayed according to the operating status at that time.
For each variable part information display data FL of Sn, display presence/absence information AVL of display data information DTI to DTm
Rewrite to "Displayed" or "Displayed fever".

In this state, the operator operates the input device 7 to
When a monitoring screen to be displayed to monitor the status of the plant 2, for example, the monitoring screen of water supply system A in FIG. 8 reads out the corresponding fixed partial information display data F1 from the monitoring screen storage device 5 and outputs the corresponding display information to the display device 6, and also outputs the identification information of the monitoring screen that is instructed to be displayed on the monitoring screen variable section display means 9. Notify.

As a result, the display device 6 first displays the display screen of the fixed portion of the monitoring screen, that is, the screen configuring the system diagram of FIG. 4(a).

The monitoring screen variable part display means 9 reads the variable part information display data FL of the water supply system A from the monitoring screen storage device 5 according to the identification information notified from the monitoring screen fixed part display means 8.

Here, considering pump P, which is a plant element of water supply system A, the display data information DT is set as shown in Fig. 6 for the flow rate of pump P, and at this time, plant automation operation It is assumed that the display presence/absence information AVL is set to display by means 4.

The monitoring screen variable part display means 9 inputs from the plant data storage table 3 and the plant data number PID is rloO.
When the value of the plant data of J is "35", in this case, it corresponds to section 1, so the monitoring screen variable display means 9 displays a display color consisting of two numbers of 16 x 8 character size. Display information for displaying a white character string "35" such that the coordinates of its reference position match the coordinates (300, 300) of the display device 6 is formed, and the display information is output to the display device 6.

As a result, the display device 6 displays a monitoring screen in which the flow rate display of the pump P is inserted at a predetermined position in the system diagram, as shown in FIG. 4(a).

Also, if the flow rate of the pump P changes to "80",
In this case, since this corresponds to section 2, the monitoring screen variable display means 9 is composed of two numbers with a font size of 24 x 12, and the display color is black and the surrounding area is yellow, that is, black on a yellow background. Form display information to display the character string "80" displayed in such a way that the coordinates of its reference position match the coordinates (300, 300) of the display device 6, and output the display information to the display device 6. .

As a result, the display device 6 displays the flow rate of the pump P at a predetermined position in the system diagram, as shown in FIG. 4(b).
It is written in larger letters than in case a) and in black on a yellow background to attract the operator's attention.

Further, when the flow rate of the pump P changes to r120J, this corresponds to section 3, so the monitoring screen variable display means 9 displays three numbers with a character size of 36 x 18, and the display color is black. The surrounding area is red, that is, the character string rlZO displayed in black on a red background, and the coordinates of its reference position are the coordinates of the display device 6 (300, 3
00), and furthermore, r
Display information is created that displays the character string "Flow rate large" as the same character string as the flow rate display, and the display information is output to the display device @6.

As a result, the display device 6 displays the flow rate of the pump P at a predetermined position in the system diagram, as shown in FIG. 4(c).
It is displayed in larger letters than in case b), and in black on a red background, which indicates the alarm condition, and furthermore, the character string [flow rate large j], which indicates the alarm content, is displayed.

Further, in an operating situation where there is no need to monitor the operation of the pump P, the display presence/absence information AVL is rewritten to "no display" by the plant automation operating means 4, so the flow rate of the pump P is not displayed on both monitoring surfaces.

Furthermore, when display information with a low display priority PRI and display information with a high display priority PRI occupy the same display area, the latter display information is not displayed because the former has a higher priority than the latter.

In this way, the display mode of the plant data changes depending on the value of the plant data, so that the operator can easily distinguish the state of the plant data from other plant data.

Therefore, even when a large amount of plant data is displayed on one monitoring screen, the operator can easily recognize plant data that is in a dangerous state.

In addition, since plant data that does not need to be monitored at that time is not displayed on the monitoring screen, the display contents of the monitoring screen displayed on the display device 6 are narrowed down to only the plan 1 to data that require monitoring. With fewer display elements, more effective monitoring can be performed.

Furthermore, since plant data with higher priority is preferentially displayed, the operator can easily recognize plant data that is becoming dangerous.

By the way, in the above-mentioned embodiment, the plant data is displayed in rows using character strings, but other display formats, for example, display using specific symbols can also be performed.

In this case, for example, when an abnormal state occurs, the display size of the symbol may be increased to further improve recognition.

In addition, by displaying symbols, etc. that normally do not require much attention, in a dark color, it is possible to reduce the health effects on the eyes of the operator, and to notice changes in the display format of other plant data more quickly. You can also

[Effects of the Invention] As described above, according to the present invention, the display format of the variable display information on the monitoring screen is changed according to the state of the corresponding process data, so that the operator can The effect is that the status can be displayed effectively.
