Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring apparatus for monitoring the operating state of each device constituting various plants and displaying the monitoring result on a display together with a block diagram.

[0002]

2. Description of the Related Art For example, in a plant monitoring device for monitoring various plants such as building facilities, water and sewage facilities,
The monitoring result is generally displayed on a display device such as a graphic panel or a CRT display device. The supervisor monitors the entire plant while looking at the information displayed on this display.

A plant monitoring device having such a monitoring function is constructed, for example, as shown in FIG. The process information indicating the operating state of each device, which is output from various devices configuring the plant 1, is input to the control device 3 via the process input / output device 2. The control device 3 is composed of a kind of computer, and a plant equipment state determination unit 4, a display output unit 5, and a configuration diagram memory 6 are housed inside. Further, an operation input device 7 such as a keyboard, a mouse, a touch panel, etc. for a monitor to input various commands, and a display 8 for displaying various information such as a monitoring result are connected to the outside.

The process information indicating the operating state of each device input to the control device 3 is determined by the plant device state determining section 4 based on the corresponding process information to determine whether or not the corresponding device is normal. , And is transferred to the display output unit 5 together with the configuration diagram of the corresponding device stored in the configuration diagram memory 6. The display output unit 5 simultaneously displays the operating state and the configuration diagram of the corresponding device on the display 8.

When the plant equipment state determination unit 4 determines that a failure or abnormality has occurred in the equipment of the plant, an alarm sound is output to urge the surveillance staff to call,
The abnormal message is displayed and output to the display unit 8.

As described above, on the screen of the display unit 8, the status of the equipment or the status of the process information to be monitored by the monitoring device,
History is displayed. The supervisor freely switches the display screen of the display 8 by using the operation input device 7 such as a keyboard for operating the screen, push buttons, pointing devices (light pen, touch panel, etc.), and Understand the condition.

[0007]

However, the plant monitoring apparatus shown in FIG. 10 still has the following problems to be improved. That is, in the event of a failure of each device that constitutes the plant or in other emergency, the supervisor will make a decision and take action based on the plant information provided from the display 8 of the plant monitoring device.

In the event of this emergency, the plant monitoring device should clearly indicate the failure location and display the failure information in detail. However, in the plant monitoring apparatus of FIG. 10, the abnormality occurrence information is always displayed on the display 8 at the same information level.

Therefore, there is a problem that the monitor cannot examine the details of the abnormality in detail only with the displayed contents. Therefore,
There is a problem that the monitoring performance of the plant monitoring device deteriorates. In addition, the supervisor must make various judgments while monitoring the condition of the entire plant even in normal operating conditions other than when an abnormality occurs. In such a normal operation state, a display information level different from that in the emergency described above is required.

However, it seems to be a mentally heavy burden for the observer to judge by looking at the detailed information of each device during normal operation as in an emergency. Individual determination of the operating state of each device may be performed by the plant control device itself,
It is desirable for the observers to be provided with information that allows them to make overall decisions.

Further, the supervisor can specify a specific device and display the plant information of the corresponding device on the display 8 together with the device configuration diagram. However, in order to change the display range of the display information, it is necessary to select the boundary frame of the display area to be enlarged or reduced with the operation input device 7 and move the frame to the changed size.

The selection operation of the boundary frame is a very complicated work, and the number of operation behaviors is large, which is a burden on the monitor.
Also, regarding the change of the display information density, an operation procedure of selecting the density change menu or button and inputting the change density magnification is necessary. As described above, in order to execute the plant monitoring control operation promptly and reliably, the burden on the supervisor increases significantly.

The present invention has been made in view of such circumstances, and when an abnormality occurs in equipment of a plant, the abnormality information and the enlargement information of the abnormality occurrence portion can be automatically displayed, and Even at times, the supervisor can easily display the configuration diagram of the part that he / she needs and the operation information of the relevant part, and display the plant status in the most visible format for the supervisor. , And to provide a plant monitoring device that can easily cope with the situation and can significantly reduce the mental burden on the monitoring staff.

[0014]

In order to achieve this object, the present invention outputs an operation state of each device constituting a plant, which is input through an input device, to a display device together with a configuration diagram of the device. Also, in a plant monitoring apparatus that determines normal abnormality of each device from the operating state and outputs necessary information including the configuration diagram of the abnormality occurrence device to a display unit, at least each part included in the configuration diagram of each device A display range table that stores information about the display range for enlarged display, and display information based on the information about the display range of the relevant part stored in the display range table in response to an abnormality determination that specifies the part of the device Display information range automatic determining means for determining the range, and information including an enlarged view of the relevant part is enlarged and displayed on the display based on the display information range determined by the display information range automatic determining means. And a shown means.

FIG. 1 is a block diagram showing a schematic configuration of a plant monitoring apparatus of the embodiment. The same parts as those of the conventional plant monitoring apparatus shown in FIG. 10 are designated by the same reference numerals. Therefore,
Detailed description of the overlapping parts is omitted.

The process information indicating the operating state of each device output from various devices constituting the plant 1 is input to the control device 10 via the process input / output device 2. The control device 10 is composed of a kind of computer,
A plant equipment state determination unit 11, a display information range automatic determination unit 12, a display output unit 13, a display range table 14, a configuration drawing memory 15, and the like are housed inside. Further, an operation input device 7 such as a keyboard, a mouse, a touch panel, etc. for a monitor to input various commands, and a display 8 for displaying various information such as a monitoring result are connected to the outside.

In the configuration diagram memory 15, for example, FIG.
The configuration diagram of each device constituting the plant, the detailed configuration diagram of each part, and the like as shown in FIG. Each configuration diagram stored in the configuration diagram memory 15 is represented by the display output unit 13.
Is read out and displayed on the display unit 8 for output.

Further, in the display range table 14, FIG.
As shown in, signals (information) indicating each operating state of each device
A screen number, a drawing range coordinate (XY), an enlargement / reduction ratio, etc. for specifying the block diagram in the block diagram memory 15 related to the corresponding signal are set for each.

The process information indicating the operating state of each device input to the control device 10 is determined by the plant device state determination unit 11 based on the corresponding process information to determine whether the corresponding device is normal. After that, if normal, it is transferred to the display output unit 13 together with the configuration diagram of the corresponding device stored in the configuration diagram memory 15. Display output unit 13
Simultaneously displays the operating state and the configuration diagram of the corresponding device on the display 8.

When the plant equipment state determination unit 11 determines that a failure or abnormality has occurred in the equipment of the plant, it notifies the display information range automatic determination unit 12 of the abnormality occurrence information and the abnormality occurrence equipment information.

Upon receiving the abnormality occurrence information from the plant equipment state determination unit 11, the display information range automatic determination unit 12 and the display output unit 13 display and output the abnormality occurrence information on the display 8 according to the flowchart of FIG.

When the flow chart is started and the plant equipment state abnormality information is received from the plant equipment state determination means 11, the display information is retrieved from the display range table 14 using the corresponding fault equipment name or process value name as a retrieval key,
Obtain the screen number that identifies the screen to be displayed, the drawing range that shows the area where the details of the faulty device or process value state are known, and the magnification when the drawing range is displayed on the actual display device. . These pieces of information are sent to the display output unit 13.

The display output unit 13 is based on the received information of the display information range such as the screen number and the magnification, and the configuration drawing memory 1
The necessary configuration diagram is read out from 5, and the corresponding configuration diagram is enlarged or reduced based on the magnification, so that the screen display information displayed on the display screen is edited and displayed and output to the display unit 8.

Therefore, the display unit 8 automatically displays the corresponding abnormal state in the display range most suitable for grasping the abnormal state of the plant that has occurred. Figure 4 (a)
(B) shows an example of changes in the display contents of the display device 8 when an abnormality occurs in the plant. FIG. 4A is an example in which the configuration diagram 15a displayed in the normal state is enlarged and displayed on the left side in the event of an abnormality, and the minimum necessary information regarding the device of interest is accurately and automatically displayed. Further, FIG. 4B is an example in which the configuration diagram 15a displayed in the normal state is enlarged and displayed in the vertical direction when an abnormality occurs.

Information such as in which direction the original configuration drawing 15a is to be enlarged or reduced when an abnormality occurs is set in advance in the display range table 14 according to the abnormality occurrence portion and the signal type. Therefore, the setting contents can be changed as necessary, and the monitoring staff can appropriately change the setting contents in advance so that he or she can easily see the contents.

As a result, the required level of display information is automatically obtained when needed, and the information range according to the situation in which the surveillance staff is required is provided to the surveillance staff.

FIG. 5 is a block diagram showing a schematic configuration of a plant monitoring apparatus according to another embodiment of the present invention. The same parts as those of the embodiment shown in FIG. 1 are designated by the same reference numerals.
Therefore, detailed description of the overlapping portions is omitted.

In this embodiment apparatus, a display information range manual determination unit 16 and an operator request input determination unit 17 are provided instead of the display information range automatic determination unit 12 in the embodiment apparatus of FIG. Furthermore, display range table 1
4 is not provided, and a selection button memory 18 is provided in the control device 10.

In the selection button memory 18, as shown in FIG. 6, for example, as shown in FIGS. 4 (a) and 4 (b), each of the states read from the configuration diagram memory 15 and displayed on the display 8 is displayed. Configuration of device and each part Information (icon) of a plurality of selection buttons 18a in which direction to enlarge or reduce FIG. 15a
Is remembered.

Each selection button 18a is displayed on the side of the display screen of the display 8 when a display area change command for the screen being displayed is input from the operation input device 7.
Then, an arbitrary selection button 18a can be designated by a touch panel or a mouse which constitutes a part of the operation input device 7.
Alternatively, it may be an actual push button provided on the desk of the observer. That is, any method may be used as long as it is an input device capable of inputting a single behavior.

Then, as in the apparatus of the previous embodiment shown in FIG. 1, the process information indicating the operating state of each equipment input to the control device 10 is stored in the plant equipment state determining section 11 as follows.
After it is determined whether or not the corresponding device is normal based on the corresponding process information, it is transferred to the display output unit 13 together with the configuration diagram of the corresponding device stored in the configuration diagram memory 15. The display output unit 13 simultaneously displays the operating state and the configuration diagram of the corresponding device on the display 8.

Then, when a display information range change command is input through the operation input device 7 in a state where the configuration drawing and the operation information read from the configuration memory 15 are displayed on the display unit 8, the operator request input determination unit 17 The display information range manual determination unit 16 and the display output unit 13 are programmed to execute the process of changing the display range according to the flowcharts of FIGS. 7 and 8.

When the flow chart of FIG. 7 is started, the operator request input determination section 19 first checks in P (program step) 1 whether or not there is an input request from the operation input device 7. Then, when there is an input request from the monitor, it is checked whether or not the request is a display information range change (P2).

When the display information range change instruction is issued at P2, the range determination counter C _R is cleared (P3).
After that, which one of the selection buttons 1 shown in FIG.
It is checked whether 8a is designated (P4).

When the left enlargement button is selected from the selection buttons 18a in P5, 1 is added to the range determination counter C _R in P6 (C _R = C _R +1). Next, the value corresponding to the amount of the range determination counter is subtracted from the left X coordinate of the display range whose display area is to be changed (P7). Here, the method of obtaining the left X coordinate is shown in Expression (a).

New display range X coordinate = display range left X coordinate−F (range determination counter) (a) Note that F is a function having the range determination counter C _R as a variable. By appropriately determining the function F, the change rate of the window corresponding to the increase of the counter can be adjusted. For example, if F (x) = x, the display range size changes in proportion to the change amount of the counter, but if F (x) = x ² , the counter increases. That is, when the button is pressed for a long time, the size of the display range changes significantly.

After determining the new display range left coordinate, it is checked whether the range of the drawn area exceeds the range of the area of the screen data to be displayed (P8). The reason for performing this inspection is that the screen displayed in the display range is stored as data of the original resolution (for example, 640 dots × 480 dots), and therefore cannot be displayed beyond that area.

If it exceeds the original screen area, nothing is done. If it does not exceed, the display range of the new magnification is redrawn (P9). Next, the left enlargement selection button 18a
It is checked whether or not is pressed (P10). If it is still pressed, the process returns to P6 and the left enlargement process is repeated. As a result, by continuing to press the same left enlargement button 18a, the counter is increased and the enlargement ratio is increased.

Therefore, as shown in FIG. 4A, the left expansion button 1 is shown in the configuration drawing 15a displayed in the normal state.
By pressing and holding the 8a button, it will be expanded sequentially. If the right enlargement selection button 18a is pressed at P11, the right enlargement display information range enlargement process from P12 to P13 is executed. Incidentally. This display information range expansion processing conforms to the left expansion display information range expansion processing of P6 to P10, and therefore its description is omitted.

Further, when the upward enlargement selection button 18a is pressed in P14 of FIG. 8, the display information range enlargement processing of the upward enlargement of the display information (configuration diagram) currently displayed on the display 8 is performed. .

Similarly, in P15 and P16, when the downward enlargement selection button 18a or the four-sided enlargement selection button 18a is pressed, the corresponding downward enlargement display information range enlargement processing and four-sided enlargement display information range Enlargement processing is executed.

In the plant monitoring device thus constructed, the formulas are expanded according to respective operations of left enlargement, right enlargement, upper enlargement, lower enlargement, four-sided enlargement, and further left, right, upper, lower, four-sided reduction. By obtaining the coordinates in (a), the coordinates can be changed simply by pressing the corresponding button. For example, in the case of left reduction, substituting the sign of the function F with a positive (+) in the expression (a) can be obtained by the expression (b).

New display range X coordinate = Display range left X coordinate + F (range determination counter) (b) As a result, the new display range X coordinate becomes larger than before the change, and thus becomes smaller as the entire display area.

As described above, when a monitor member wants to perform an operation from the normal monitor display screen, to check a wide range of information when an abnormality occurs, or to display a lot of local information on the screen, Enlarge easily by simply pressing and holding the corresponding selection button 18a. Reduction can be realized.

The present invention is not limited to the above embodiments. For example, in the apparatus of the embodiment shown in FIG. 1, an example of changing the display range when an abnormality occurs in the plant is described by changing the size and density of the display range, but the information after the change is displayed on the display unit 8. The window may be displayed at another position on the display screen.

Furthermore, in the above-described embodiment, the display information is changed by enlarging or reducing the display area without changing the density of the drawing information in the window. For example, as shown in FIG. It is also possible to enlarge (zoom in) or reduce (zoom out) the drawing information in the display area without changing the size of.

Therefore, the observer is. When you want to grasp the entire plant, you can zoom out to display a wider area, and conversely, you can zoom in to display detailed information for each device. That is, the monitor can display the information having the desired display density on the display 8 simply by pressing the corresponding selection button 18a.

[0052]

As described above, according to the plant monitoring apparatus of the present invention, the occurrence of an abnormality is provided by providing the display range table for storing the respective enlargement ratios in the case of enlarging and displaying the configuration diagram of each device constituting the plant. Sometimes, the information including the abnormal part is automatically enlarged and displayed.

Therefore, in the event of an abnormality, the observer can easily determine and deal with it, and reduce the workload.
The mental burden on the observer can be reduced. further,
By a simple display range change request such as enlargement / reduction input from the operation input device, even during normal operation, it is possible to enlarge / reduce the configuration diagram of the part that the supervisor needs and the operation information of the corresponding part. The plant status can be displayed in a form that is most easy for the observer to see, and the work burden and mental burden of the observer can be further reduced.
