0001

[Industrial Field of Application] The present invention relates to a CRT monitoring and display device used in a monitoring and control system for monitoring and controlling the operating status and failure status of equipment in plants, building facilities, etc. to be monitored and controlled. It frees the operator from the hassle of having to deploy screens in a top-down manner each time, and eliminates operational confusion regarding function screen selection.
CR that improves the operability of CRT monitoring work
This invention relates to a T-monitoring display device.

0002

[Prior Art] Conventionally, in monitoring and control systems employed in plants and building facilities, for example, when displaying the status of a signal to be monitored and controlled on a CRT screen, it is displayed on a desired function screen to achieve the purpose. The status of the signal is monitored.

[0003] In other words, when displaying the status of signals to be monitored and controlled on a CRT screen, a point display function (a function that displays various information for each input/output signal of the system for each signal/point), real-time Trend display function (a function that samples specified signals at specified intervals and displays them as a trend graph in order to view temporal changes in various system input/output signals and the correlation between two or more pieces of data in real time) Historical trend display function (This is a function for viewing the temporal changes in various input/output signals of the system and the correlation between two or more pieces of data, but unlike the real-time trend display, it is a function for viewing the past 48 hours sampled at 1-minute intervals. (Function to display trend graphs based on data), Bar graph display function (Function to display process values input to the system as a bar graph of six arbitrary items as one group for comparative confirmation), Graphic display function (a function for monitoring the current status of the plant by creating a graphical overview of various plant equipment and displaying the operating status of equipment along with measured values on a CRT screen); (a function for displaying values as integrated values or digital values), a history display function (a function for displaying failure states of process values input into the system in chronological order), and a histogram display function (a function for displaying failure states of process values input into the system). (a function for displaying process values in a bar graph), an alarm list display function (a function for displaying current failures of process values input to the system and a list of them by color), tabulation maintenance function (a function for displaying data for reports) For each function screen, such as editing, saving form data to FD, loading form data from FD, changing the form printing time, printing printer, etc., from the menu screen to the submenu screen on the CRT screen. , select the signal or the group containing the signal, and select
Finally, I was able to confirm the status of the desired signal on the CRT screen.

[0004] Hereinafter, screen development in the conventional method will be explained in detail.

[0005] In the conventional method, for example, A is displayed on a bar graph display.
When you are monitoring the pump power receiving current and want to see the past trends in this signal, as shown in Figure 17,
By hitting the function screen name, the "Historical T" 204 portion of the "menu bar" 281, which can be expanded to the CRT function screen, is hit with the mouse to display the historical trend menu screen. Next, from this historical trend menu screen, find the registered group 282 of the A pump power receiving current (an enlarged view is shown in Figure 18) by performing the operations on the previous page 282 and the next page 283, and enter its number. Select it and expand it to the historical trend screen.

[0006] In the above example, if you want to see the tabulated data of the A pump receiving current,

[0007]
However, in the conventional method described above, when an operator wants to check the status of a noteworthy signal on another function screen from the expanded function screen, he or she memorizes the signal name and then selects it from the menu again. You have to select it (from the menu bar 281), and also check where the desired signal is located on each function screen (in which group it is registered or not, and the ID number of the signal (signal You must know in advance what the unique number assigned to each type was. This results in a system that can only be operated smoothly by a limited number of operators who use the system all the time.
It is a heavy burden on the operator. If you do not know which group contains the signal you want to display, you can turn the pages by performing the operations on the previous page 282 and next page 283 until the group containing the signal you want to display appears on the group display screen. There must be. In particular, when the procedure to reach the target screen spans multiple layers, such as tabulation maintenance, and the amount of data to be displayed on one screen is large and the display time is long, it is necessary to search for which sheet has the target signal. This is a very heavy burden on the operator. Furthermore, in buildings and other facilities, where there are a large number of screens and screens must be expanded over multiple levels, backtracking due to operational errors is unavoidable.

[0008]

[Problems to be Solved by the Invention] As described above, conventionally, when you want to check the status of a noteworthy signal from an expanded function screen on another function screen, you have to check the state of a signal from the menu bar in a top-down manner each time. There are problems in that the CRT monitoring operation is complicated, and the operation of selecting a function screen is confusing, and the operability of CRT monitoring work is very low.

[0009] An object of the present invention is to enable the screen to be expanded top-down from the menu bar each time by enabling the expansion to the desired function screen by two-move operations with the mouse between each function screen. An object of the present invention is to provide an extremely reliable CRT monitoring display device that can free an operator from complications, eliminate operational confusion regarding selection of function screens, and significantly improve the operability of CRT monitoring work. .

0010

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a monitoring and control system for monitoring and controlling the operating status and failure status of equipment in monitoring and controlling objects such as plants and building facilities. , when displaying the state of a signal to be monitored and controlled on a CRT screen, the desired function screen such as bar graph display, historical trend display, etc. is displayed to monitor the state of the target signal.
In an RT monitoring display device, when the signal name of a noteworthy signal in the function screen currently displayed on the CRT screen is hit with the mouse, a skip window displaying the names of multiple function screens is moved to the CRT screen. When a portion of the function screen name to be displayed in the skip window displayed by the skip window display means is hit with a mouse, a function screen corresponding to the name is displayed on the CRT screen. CRT
It is configured to include a skip means consisting of a screen display management means.

[0011]

[Operation] Therefore, in the CRT monitoring display device of the present invention, by hitting the signal name part between each function screen with the mouse and selecting the function screen from the skip window displayed in response, two actions can be performed. Equipped with a skip means that enables expansion to the desired function screen by operation, the status of the signal to be monitored and controlled can be displayed on the CRT.
When displaying on a screen, the function screens are expanded by two behavior operations when the screen is developed focusing on one signal, so the operator is not required to perform top-down operations from the menu bar as described above. CRT, eliminating operational confusion regarding selection of function screens.
The operability of monitoring work can be improved.

It consists of.

Next, C of this embodiment configured as above.
The operation of the RT monitoring and display device will be explained. In FIG. 1, the plant data input means 106 includes a plant 10
5, plant data is input from the plant 105 at regular intervals. Based on this plant data, the input signal file creation means 107 generates an input file (digital signals such as status, failure, etc., analog signals such as process values, pulse signals such as integrated values) 1
08 is created and displayed on each function screen managed by the CRT screen display management means 109, that is, in this example, the bar graph display means 110, the historical trend display means 111, etc.

On the other hand, in the mouse management means 101,
As shown in FIG. 7, a request from the CRT screen display management means 109 is checked (1102), and if there is an input request (1103), the system waits for mouse input. Next, the input is checked (1104) and whether the mouse button has changed (1105). When a mouse button change is detected, the displayed windows are checked and the window hit by the operator is searched (1
106-1107). As a result, if a window hit by the operator is found, data is retrieved from the information record for that window (details are shown in FIG. 13). Next, it searches for where in that window you hit. In other words, did you hit a control (1109) or hit an icon (1110)?
are checked, and data is extracted from the control information record (details shown in FIG. 14) and icon information record (details shown in FIG. 15) according to each (1110, 1112). And this information is shown in Figure 1
The data are compiled into a data format as shown in 6 and notified to the CRT display screen management means 109 (1113).

Next, in the CRT screen display management means 109, the object to be notified is determined from the information notified above, and information regarding the function screen is notified to each function screen. The operation of the CRT function screen display means 109 is shown in FIG. That is, in each function screen display means 110, 111,
A request from the CRT screen display management means 109 is checked (1002), and the display (100
3, 1008, 1009, 1010), control processing (1004), icon processing (1005), mouse processing (1006), and other processing (1007).

When a display request is made, it is checked whether the signal name appears on the requested screen (1008), and if the signal name is to be displayed, the display signal registration table as shown in FIG. 10 (114 in FIG. 1) is checked. For each signal name, signal type (process value, digital value, integrated value, hourly data, daily data, monthly data, etc.), each signal type, and the identification number (ID) assigned to each signal. number) and the coordinates indicating the display area of the signal name displayed on the screen are registered. After completing the registration, a request screen is displayed (1010).

On the other hand, if the request from the CRT screen display management means 109 is for mouse input processing, the processing shown in FIG. 8 is performed. That is, first, the display signal registration table is checked (1202-1203). and,
If the clicked coordinates match the coordinates of a signal in the display signal registration table 114, a skip window is opened (1205). In this case, information necessary for opening is extracted from the skip window display information table 116. At this time, the record number of the hit signal is saved from the display signal registration table 114 (1206). If no signal is present, other CRT function screen processing is performed (1204).

On the other hand, in the CRT function screen processing, as shown in FIG. 9, the window type is checked from the contents notified from the CRT screen display management means 109 (140
2-1403). If it is not a skip window, further processing is performed, and if it is a skip window, whether or not the hit location is the CRT function screen name is determined by the skip window display information table (details are shown in Figure 11). (1405).

As a result, if it is not the name part of the function screen, there is no processing and the process ends. In addition, if it is the name of a function screen, the group file name is extracted from the skip window display information table 116 (1407), and the name is saved from the group file (details are shown in FIG. 12) when the skip window is opened. A group number is extracted based on the type of signal and ID number set (1408). This retrieved information is then displayed on the CRT function screen display means 110, 111.
The notification is sent to the CRT screen display management means 109 through (
1409). Further, upon receiving this notification, the CRT screen display management means 109 displays the screen.

[0025] When the above procedure is visually followed, it is as follows. Now, as shown in FIG. 2, for example, while displaying the bar graph display screen 201, A of the bar graph 202 is
Assume that a request to display a historical trend graph of the pump power receiving current 203 is made. In this case, as shown in FIG. 2, hit the signal name 203 with the mouse. That is, hit somewhere in the signal name area 301 shown in FIG. 3 with the mouse. Then, a skip window 205 is displayed. Here, if you want to display the historical trend, hit the area labeled historical trend display 207 on the skip window 205, as shown in FIG. This enlarged view is shown in FIG. Then, by hitting this part, the historical trend display screen 20 including the A pump power receiving current is immediately displayed.
6 is expanded.

[0026] This frees the operator from the trouble of displaying the historical trend display top-down from the menu bar as in the past, eliminates operational confusion regarding selection of function screens, and improves the operation of CRT monitoring work. can significantly improve performance.

As described above, in the CRT monitoring display device of this embodiment, when the signal name portion of a noteworthy signal in the function screen currently displayed on the CRT screen is hit with the mouse, a plurality of A skip window displaying the name of the function screen is displayed on the CRT screen, and when the part of the skip window with the name of the function screen that you want to display is hit with the mouse, the function screen corresponding to that name is displayed on the CRT screen.
This is displayed on the RT screen.

[0028] Therefore, you can move between each function screen by using the mouse.
By being able to immediately deploy to the desired function screen using behavior operations, the operator is freed from the complication of having to deploy the screen in a top-down manner from the menu bar each time, as in the past, and this eliminates operational confusion regarding function screen selection. This makes it possible to significantly improve the operability of CRT monitoring work. In addition, in addition to the conventional CRT screen display for monitoring and control, which focuses on the function screen, by adding a signal-centered screen development function, we can display the current and past states of noteworthy signals, as well as the relationship between them and other signals. It makes it easy to compare and check the monitoring status, etc., and ask questions such as “What was this signal doing yesterday?” “What will happen in the future?” “I want to compare it with other signals!” “An alarm for this signal was issued yesterday.” This makes it much easier than before to develop screens that reliably meet the operator's needs, such as "Is this really the case?" This makes it possible to perform macro monitoring of the plant viewed from the functional screen, as well as micro monitoring focusing on a single signal, from monitoring mainly based on the functional screen, and can meet a variety of purposes.

In the above embodiment, the case of displaying on the same CRT screen was described, but if there are multiple CRTs, by displaying the CRT selection window and displaying on the other CRT screens, It becomes possible to perform multifaceted signal analysis and analysis without losing the screen before development.

[0030]

[Effects of the Invention] As explained above, according to the present invention, by hitting the signal name part between each function screen with the mouse and selecting a function screen from the skip window that is displayed in response, two Equipped with a skip means that allows you to expand to the desired function screen using a behavior operation, and immediately expand to the target function screen by performing two behavior operations between each function screen with the mouse. An extremely reliable CRT monitoring display that frees the operator from the complexity of top-down screen development, eliminates operational confusion regarding function screen selection, and significantly improves the operability of CRT monitoring work.
