Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plant monitoring apparatus suitable for monitoring a plant having a plurality of systems, such as a power plant.

[0002]

2. Description of the Related Art Plants, such as thermal power plants and nuclear power plants, take thermal power plants as an example and cover a wide area, including main engines such as boilers, turbines, generators, condensers, feed water heaters, and pumps. Auxiliary equipment such as etc., various power supply equipment, various pipes connecting these to each other, electric wire group, control device, fuel equipment, many types of equipment such as computers are arranged in many combinations,
Multiple systems are configured.

[0003] A plant monitoring apparatus for monitoring the operation state of a plant, which is such a huge system, includes a variable section screen data expressing various process amounts transmitted from monitoring points provided at various parts of the plant, and a plant monitoring apparatus. This is to monitor the state of the plant by synthesizing fixed screen data such as a plant system diagram, a trend graph, and a group device operation screen stored in advance in the apparatus and displaying them on one screen. In this case, the monitoring location in the plant is called a process quantity input point (abbreviated as PID) or simply a point, and this point is registered in the point information file. FIG. 23 shows an example of this point information file. In this point information file, the system to which the point (PID) belongs, the input value, and the history data are stored.

[0004] By the way, in a newly installed plant monitoring device,
There is a tendency that new functions are added to the display function year by year so that the state of the plant to be monitored can be grasped in various aspects. Examples of functions include trend graphs, group trends, plant system diagrams, data lists,
There are alarm screen, driving log, equipment operation window, automation screen, etc.

The trend graph linearly displays the measured process data on an XY diagram in which the X-axis is time and the Y-axis is a data range width for each measurement point in chronological order. It monitors changes in process data over time. The plant system diagram categorizes the plant by each system and displays the process data actually measured on the plant and the installed equipment on a graphic screen. Used to monitor the situation collectively. The alarm screen is displayed on the alarm window (icons and buttons that indicate which systems and devices have generated alarms) on the screen when an alarm is generated due to a system error, and an alarm message is displayed. Is displayed on the screen. The driving log calculates data of various items to be monitored based on process values from respective points detected at certain time intervals, and displays the data values in a format such as a list. By monitoring the change in the data value, it is possible to discover an abnormality in the operating state.

[0006] The equipment operation window displays equipment operation switches, process data, equipment operation status, and the like for each equipment by processing the equipment operation of the plant, which has been conventionally performed by a hardware switch, by software, and displays the data on a monitoring screen of the plant monitoring apparatus. The information is displayed to enable the operator to operate the device from the plant monitoring device. This device operation window is prepared for each operation target, and the CRT
Since the operator operates each device from a window displayed on the screen of the display as described above, it is also called a CRT operation operation frame.

[0007] The automation screen is as follows. That is, in a power generation plant, for example, a plant automation device is introduced to automate operation such as plant startup. This plant automation apparatus is designed to compare pre-designed logic data with an actual plant state and generate an automatic operation command or an operation guide for equipment. As described above, the automation of the plant is controlled by logical data incorporated in a computer designed in advance, but the logical data is basically a condition that describes the timing for generating any operation command. And a condition describing a premise for the operation and a condition describing completion of the operation. Note that these conditions regarding the point to be monitored are stored on the automated plant table. The description of the timing for generating the operation command defines a so-called operation procedure of the plant, and the description of the premise and completion defines the monitoring items before the operation. Therefore, if a failure occurs in any system constituting the plant and the plant state deviates from the standard plant operation procedure, the conditions described in the logical data will not be satisfied, and the progress of the automated operation of the plant will be stagnated. become.

Accordingly, the plant monitoring apparatus is provided with, as one of its display functions, an automation screen for monitoring the progress of the automation. The automation screen is used to capture the plant data and monitor the progress of the plant. Then, when a defect occurs, defect information including the point at which the defect occurred, the table number, the content of the block eye, and the like is output. Then, on this automation screen, a logic chart describing the logic data of the automation is displayed,
Various display functions related to automation are prepared in order to specify processing when a problem occurs.

Each P provided on the system as described above
For example, IDs are classified by system such as boilers, turbines, and generators. However, when the system becomes huge, the number of constituent devices and systems also increases. It is necessary to group and monitor. Therefore, the group to which each PID belongs is recorded, and the information is displayed only for a specific group in a certain system. For example, when the series to be monitored is a low-pressure heater, as a plurality of related process amount input points PID,
The low pressure heater outlet temperature, the low pressure heater outlet flow rate, the low pressure heater outlet pressure, the low pressure heater outlet fully open, the low pressure heater outlet fully closed, and the like are stored in advance as one group. In addition, in the system, the system consisting of a combination of the same type of equipment,
Some systems consist of combinations of different devices. Also, as in the case where the system switches with the progress of the operation of the plant, one device or PID may belong to a plurality of different systems or groups.

FIG. 24 shows an example of a group information file in which the relationship between each PID and its group is recorded. The group information file of FIG. 24 has a dedicated table for each function displayed by the monitoring device, and for each table, the group number of each group and the group number.
Are listed. For example, FIG.
Shows a list of groups that can be displayed by a specific function (for example, a trend graph). In this function, groups 1 and 2 are groups belonging to a boiler system, and each group has PIDs of a plurality of different boilers are registered.

By the way, in order to monitor each device by the plant monitoring device, an operator selects necessary devices and display functions from an interactive input / output device provided in the monitoring device, so that the desired device can be monitored. Get information about types and functions. That is, as a method of calling a necessary function from the menu displaying various functions as described above, a configuration is adopted in which the selection of the hierarchical menu screen is repeated to reach the terminal function. In addition, when acquiring information (outputting to the display interactive device), a plurality of pieces of information can be acquired simultaneously as much as possible.
A display screen such as a display is divided into a plurality of screens, and a plurality of functions are displayed on one screen. For example, the screen is divided into four, and display functions such as a trend graph, a plant system diagram, and a warning message display and a selection menu screen thereof are assigned to each divided screen (also referred to as a window).

An example of a conventional plant monitoring apparatus using such an interactive input / output device will be described with reference to FIG. The plant monitoring device 1 includes a display interaction device 2 having a screen data display function such as a display and an interaction request input unit such as a keyboard and a mouse. Various requests are input from the display dialogue device 2 to the plant monitoring device 1 by a dialogue operation of an operator. The plant monitoring apparatus 1 includes a full-function menu interactive unit 10, a function selection calling unit 11, an individual function processing unit 12, and a display arrangement processing unit 13. The all-function menu interaction means 10 displays the all-function menu in response to an interaction request from the display interaction device 2, and displays the selected function and the group number within the function.

That is, as shown in FIG. 27, when the all function menu 130 is displayed on the screen of the display / interaction apparatus 2 and a specific function is selected by an operator who has viewed this menu 130, the selected function (FIG. In the example, a group selection menu 131 for displaying a group belonging to the function 1 trend graph) is displayed. In addition, the operator selects a group selection menu 1
When a specific group (group 3 in the example in the figure) is designated from 31, these selection results are notified to the function selection calling unit 11. The function selection calling unit 11 searches for the individual function processing unit 12 corresponding to the function and group information recognized by the all-function menu interaction unit 10 and notifies the individual function processing unit 12 of the information.

As shown in FIG. 26, the individual function processing means 12, based on the function and group information notified from the function selection calling means 11, assigns P
Display data collection means 1 for collecting monitoring information related to IDs and processing image generation information for displaying the information related to PIDs in a form corresponding to a designated function
2a. Specifically, the display data collecting means 12a generates display screen data by dividing the notified function / group information into fixed part screen data and variable part screen data required for display. Therefore, the display data collection unit 12a includes the variable part screen data generation unit 12
b is connected. This variable part screen data generating means 1
2b is the point information file 12 shown in FIG.
With reference to c and the group information file 12d, information of each PID belonging to the group to be displayed is obtained, and variable section screen data is generated. Also, the display data collecting means 1
2a is a fixed part screen data file 12e storing data required to display a fixed screen corresponding to each function.
See When the function is a trend graph, the fixed portion screen data is a portion commonly displayed in all trend graphs, such as a graph frame and a scale line.

In such a conventional monitoring device, when the function selecting and calling means 11 notifies the individual function processing means 12 of "displaying a trend graph of function 1 with respect to PIDs belonging to group 3". , The display data collecting means 12a includes a fixed part screen data file 12e.
Then, data on the corresponding function is extracted from, and fixed part screen data is generated. At the same time, the display data collection means 12a
The group information is notified to the variable part screen data generating means 12b, and the points belonging to the designated group of the function are extracted by referring to the group information file 12d of FIG. 24 having the table for each function. In this case, the point PID (T4) belonging to the group 3 is extracted from the table of the function 1 in the group information file. Furthermore,
The variable part screen data generating means 12b extracts the extracted point P
Regarding ID (T4), T which is data necessary for display from the point information file 12c having the configuration of FIG.
The input value and the history data stored for the PID (T4) of the (turbine) system are extracted, and this is notified to the display data collection means 12a as variable portion screen data.

As a result, the display data collecting means 21a combines the data of the fixed part and the variable part, generates display screen data, and notifies the display arrangement processing means 13 of the data. The display arrangement processing means 13 performs processing based on the received display screen data.
The trend graph 132 is interrupted and displayed on the screen of the all function menu as shown in FIG. 27, or it is determined from which of the screens which can be divided into four sections as shown in FIG. Then, display screen data is output to the corresponding section. The display interactive device 2 receives the output result and displays the screen. The display screen 1 in FIG.

In addition to the menu, the configuration described in each claim is added. Note that the configuration of all function menu portions described in the related art is denoted by the same reference numeral in the drawings, and description thereof will be omitted.

(1-1) System Menu Dialogue Means 20... Corresponding to Claim 1 In this embodiment, all function menu dialogue means 10
In parallel with the function selection calling means 11, a system menu interaction means 20, a system calling means 21, a selection window display means 22, and a dialog processing means 23 are provided. The system menu interaction means 20 recognizes the system classification and the function selected by the plant monitor 1 by the interactive operation from the system menu. The system call means 21 is connected to the system menu interaction means 20.
A function group number is searched based on the system and function information selected by the notification from, and the selected function and the searched group number are notified to the corresponding individual function processing unit 12. That is, as shown in FIG.
Reference numeral 1 denotes a system / function determination unit 21a for detecting the system and function notified from the system menu interaction unit 20, and a function group for extracting a group number matching the system selected based on the determination result of the system / function determination unit 21a. Search means 2
1b. The function group search unit 21b stores the function group information stored in the system group information file 42 for managing the correspondence between the function group and the system classification.
The system classification correspondence table 421 is searched, and a group corresponding to the specified system classification and function is determined.
As shown in FIG. 4, the system group information file 42 includes, for each function, a group for each function that lists a group belonging to the function and a system classification to which the group belongs.
System classification correspondence table 421 and system classification list 421
And

The selection window display means 22 displays a list of functions corresponding to the system or group specified by the system call means 21 or the like, or displays other options such as groups and points. The processing means 23 enables a desired function or group to be selected from the list displayed by the selection window display means 22. The interactive processing means 23 can also display a dedicated selection screen other than the window displayed by the selection window display means 22. The system call means 21 and the selection window display means 22
Then, the information obtained by the interaction processing means 23 is notified to the individual function processing means 12, and the individual function processing means 12 performs various function displays related to the designated system or group according to the information.

Next, the operation of the system menu interactive means 20 will be described. FIG. 3 shows a display screen displayed on the display / interaction apparatus 2. The display screen 100 has four divided display screens 101 to 104 and a task bar 105 arranged around the display screens. ing. On the task bar 105, a system menu PB (push button) 10 for calling the system menu dialogue means 20 is displayed.
6 are arranged. In this state, in order to call the system menu of the present embodiment, when the system menu PB is selected, the system menu interactive means 20 is operated, and the system classification list is displayed on one of the display screens (for example, the screen 103). A system menu 108 corresponding to 421 is displayed.
Therefore, the operator selects a system classification (turbine-related in the example in the figure) for which a display request is made from the system menu 108. When a system to be displayed is selected from the system menu, the system menu interaction means 20 operates to display a function selection window for selecting a function prepared for the selected system. , A desired individual function (trend graph in the example in the figure) is selected. In this way, when an individual function is selected on the dialogue screen generated by the system menu interaction means 20, the system menu interaction means 20 recognizes the system classification and individual function selected by the interactive operation and notifies the system call means 21. I do.

In the system call means 21, the information of the system classification “T (turbine related)” and the function “1 (trend graph)” selected by the system menu dialogue means 20 are systematized.
The function determining means 21a receives the information and notifies the function group searching means 21b of the information. The function group search unit 21b refers to the function-by-function group-system classification correspondence table 421 from the information of the system classification "T" and the function "1",
The corresponding group number “3” in the function is detected. The function group search unit 21b notifies the function “1” and the group No. “3”, which are detection results, to the individual function processing unit 12.

The following processing is the same as the operation of the individual function processing means 12 shown in FIG. That is, the display data collecting means 12a in the individual function processing means 12 which has received the notification extracts the fixed part screen data necessary for the trend graph display from the function "1 (trend graph)" from the fixed part screen data file 12e, Further function "1"
And the group No. “3” are assigned to the variable part screen data generating means 12b.
Notify to The variable section screen data generating means 12b is a group information file 12d related to the trend graph function.
From FIG. 24, point information “PI” in group No. “3”
D (T4) ", and the point information" PID (T
4) Point information file 12c corresponding to "" (FIG. 23)
, And generates variable section screen data based on the input values and the history data (curve), and returns the screen data to the display data collection means 12a. The display data collecting means 12a combines the fixed part screen data and the variable part screen data, and notifies the display arrangement processing means 13 of the completed display screen data. This means outputs the received display screen data to the screen section (the screen 104 in the example of FIG. 3) for which a display request has been made, and a “trend graph (turbine)” is displayed on the display interactive device 2.

The trend graph of function 1 is as follows.
When the boiler B is selected as the system classification, the function group search unit 21b extracts a group 1 and a group 2. In this case, the respective trend graphs may be displayed for two sections on the screen, or the two displays may be switched and displayed for one section specified in advance. Further, it is also possible to operate the interactive processing means 23 to display a group selection screen, and prompt the operator to input which group the trend graph is to be displayed.

As described above, one section 10 of the screen is displayed.
After displaying the function having the system to be designated on the screen 4, the same operation is repeatedly performed on the other sections 101 to 103 for the same system to display the necessary functions on all screens. Can be. In the example of FIG. 3, the system and function selection screen is displayed on the screen 103, and the function trend graph of the selected turbine-related system is displayed on the screen 104. After that, the system and function selection screens may be switched to display the function trend graph of the selected turbine-related system on the same screen 103. Further, a system and function selection screen is displayed continuously on a specific screen 103, the functions of the system selected in order are displayed on other screens 101, 102, and 104. The selection screen can be switched to another function display screen.

As described above, according to the present embodiment, the operator can display the requested screen only by selecting the system and the function without searching for and recognizing the group number in the function. Becomes In particular, when monitoring a plant, it is often desirable to obtain information on points belonging to a particular system or group from a multifaceted viewpoint.In such a case, the system or group to be displayed is repeatedly input. Work is unnecessary,
Only the function desired to be displayed for the system or group once specified has to be specified, so that the workability is improved. Furthermore, between the system classification and the group, the number of groups is larger, and it is troublesome to select a desired group from a group having many choices in the conventional specification in the order of function selection and group selection. In the present embodiment, the system to be specified may be selected from among the system classifications with relatively few options, and the selection operation is simple. In addition, depending on the system, it is often not required to display all functions, and it is better to select a function related to the specified system from the specified system as in the present embodiment, as in the prior art. Is much easier to operate than choosing

As a result, for example, when a function group related to the same plant system classification is called in four sections of the screen from the conventional all function menu, the all function menu display (1)-
Function search (2)-Select applicable function (3)-Group list display
