Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen display method in a computer system or a display device as a terminal device user interface.

[Related Art] Conventionally, terminal devices such as various computer systems and workstations are provided with a display device such as a color CRT and a pointing device such as a keyboard and a mouse as a user interface. Various data are displayed on the screen of the display device.

[Problems to be Solved by the Invention] However, various problems arise when a conventionally known screen display method is applied to a specific system. For example, as a screen display method, a multi-window display method, a split display method, and the like are known. However, when these are adopted in a building management system, there are the following problems. That is, in the building management system, power supply management for managing facilities such as power receiving and distribution facilities, emergency power generation facilities, and lighting facilities, air conditioning management for managing facilities such as cooling and heating facilities, air conditioning facilities, water supply and drainage facilities, hot water supply facilities, and sanitary facilities. Sanitary management to manage equipment such as equipment, fire and fire alarm equipment, fire and fire prevention equipment, smoke and smoke prevention equipment, disaster prevention and crime prevention management to manage equipment such as evacuation guidance equipment,
Transportation management to manage equipment such as elevators and parking lots,
It is necessary to manage various facilities, such as business management for managing facilities such as telephone facilities and broadcasting facilities, etc., and accordingly, create and display schedules for inspections of each facility, and show trends in normal and abnormal conditions of each facility. In the heating and cooling heat source system, the temperature display of each part, in the power system, the currently used power amount obtained as a result of demand monitoring, and the display of the predicted power amount in the relatively short future of about 30 minutes to 1 hour, In addition, various data can be created or displayed, such as creation and display of a daily report or a monthly report summarizing the state of each facility, and it is necessary to comprehensively judge data related to each other to perform building management. Because there is
It needs to be able to display multiple data at the same time.

On the other hand, conventionally, when a plurality of data are to be displayed, means for arranging a plurality of display devices, adopting a multi-window method, or dividing a data display area into a plurality of pieces are known. However, in the method of arranging a plurality of display devices, not only the whole device becomes large, but also it is troublesome to compare displayed data, and in the multi-window method, a plurality of data are displayed in one screen. Although it is possible to display, it is often displayed by overwriting some data with other data, so if you try to display each data so that it does not overlap, you must move the window, Was also troublesome, and involved considerable inconvenience. Also,
In a method in which one screen is divided into a plurality of regions, for example, four regions, data displayed in each region does not overlap with data displayed in other regions, but is always divided into four regions. As a result, it is not possible to display only one data item of interest on the screen.

In addition, in any of the conventional display methods, it is common to use a pointing device to operate the screen, but since numeric input is performed using a numeric keypad arranged on a keyboard, In this case, both the pointing device and the keyboard must be operated, resulting in poor operability. As described above, the conventional screen display method has a problem in terms of visibility and operability.

The present invention has been made to solve the above problems, and has as its object to provide a screen display method with good visibility and operability.

[Means for Solving the Problems] In order to achieve the above object, a screen display method according to the present invention includes a display screen in which at least a function selection area, an alarm display area, a numeric keypad display area, and a data display area are set. In one screen display method, the data display area can be divided into a plurality of windows as needed.

[Functions and Effects of the Invention] According to the present invention, the data display area can be divided as needed, so that only one screen can be displayed in a large size, and of course, a plurality of screens can be simultaneously observed and compared. it can. Further, since the numeric keypad is also displayed in a predetermined area of the display screen, the screen operation can be performed only with the pointing device, and the operability is good.

Furthermore, since a warning area is assigned to a predetermined position on the display screen, a warning displayed when an erroneous operation or the like is always displayed at a predetermined position, and the visibility of the warning is good.

[Example] Hereinafter, an example will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an embodiment in which a screen display system according to the present invention is applied to a building management system. In FIG. 1, 1 is a central control device, 2 is a display control device, and 3 is a display device. 4 is a keyboard, 5 is a pointing device, 6
Indicates a storage device, and 7 indicates a communication line.

In FIG. 1, the central control device 1 is connected via a communication line 7 provided between each facility (not shown) managed by the building management system.
The status of each facility is grasped by receiving data sent from each facility and output signals of various sensors (not shown) arranged in each facility, and instructing each facility as necessary. This is a process of building management of giving. The display control device 2 displays various data in a mode instructed by the operator, and details thereof will be described later. As the display device 3, a CRT, a liquid crystal display device, or the like can be used. In this embodiment, a color CRT is used. The keyboard 4 and the pointing device 5 are provided as input devices. As the pointing device 5, for example, a mouse is used. Although not shown, the cursor of the pointing device 5 may be a conventionally known pattern such as an arrow pattern or a cross-shaped pattern.

The storage device 6 needs to have a large capacity enough to store data about each facility to be managed and various other data, and uses a large-capacity storage device, for example, a large-capacity floppy disk device. .

The screen of the display device 3 is displayed as shown in FIG.
16 are divided into six regions. The area 11 is a date and time display area in which the date, day of the week, day of the week, and current time are displayed in units of minutes. Since the central control device 1 keeps the clock at a regular time by the clock, the display control device 2
Can be displayed by inquiring of the central control device 1 about the current date and time, day of the week, and time.

The area 12 is a function selection area in which items for mainly selecting a screen display mode are displayed. FIG. 2 (b) shows the area 12
This shows an example of a key provided in the "Erase All" to erase all data displayed on the screen and the "Alarm Erase" to erase the alarm message displayed in the alarm display area 16. "A mode" for selecting an A mode for displaying only one screen, "B mode" for selecting a B mode for displaying two screens simultaneously, and switching between a base screen and a window screen in the B mode. "Switching" to perform, "C mode" to select the C mode for displaying four screens simultaneously, "Record" to select whether or not to print screen operation records such as start and stop on the printer, and "Start" , "Prohibit" for selecting whether to prohibit / not prohibit screen operations such as stop, and a printer (not shown)
"Print" to print the screen hard copy displayed on the screen
Each key is arranged. Therefore, the operator can easily select a desired function by instructing a key on which a desired item is displayed by the pointing device 5. The display modes A, B, and C will be described later.

The area 13 is a data display area in which data for building management is displayed. The area 14 is an area where basic function selection items are displayed, an example of which is shown in FIG. 2 (c).
In FIG. 2 (c), a "table of contents" for displaying the table of contents in the area 13 and "+" for calling the previous screen one page later.
“1”, “−1”, “previous screen” for calling the screen displayed immediately before the currently displayed screen, “start” for remotely starting the device selected on the screen, screen “Stop” for remotely stopping the device selected above, “Setting” for transferring set value data such as temperature and humidity of the device selected on the screen to the central control device 1, and a screen Each key of "cancel" for canceling the selection of the device selected above is arranged.

The area 15 is an area where a numeric keypad is displayed, for example,
As shown in FIG. 2 (d), ten numbers "0" to "9", decimal point ".", Colon ":", bar "-", clear key, backspace key, set key, etc. Is arranged. An area 16 is an alarm display area for displaying a warning at the time of an erroneous operation or various messages, information, and the like. An area of about three lines is secured. Therefore, when the display control device 2 detects an erroneous operation, a predetermined alarm is displayed in the area 16. The area 16 can be provided with an up / down scroll function. In this case, the alarm history displayed by a scroll key (not shown) can be checked. I have. The reason why the scroll key is not displayed on the screen is that there is no inconvenience in terms of operability even if a function that is used very little, such as a history of alarms, is selected with the keyboard 4. This is because it is possible to display only the keys necessary for the screen selection.

When the power is turned on to the central controller 1 and the start-up process is completed, the central controller 1 instructs the display controller 2 to display an initial screen. An example is shown in FIG. In FIG. 2 (e), the regions 11, 12,
The above-described display is performed on 14 and 15, and the first page of the table of contents is displayed on the area 13. Hereinafter, the region 16 is omitted.

Next, three types of screen display modes, A mode, B mode, and C mode, will be described.

In the A mode, as shown in the table of contents shown in FIG.
This is a mode in which desired data is displayed over the entire area 13, and the A mode is activated when the system is started. And in A mode,
The display color of the 12 A-mode keys 20 is changed from a display color indicating a non-selected state, for example, blue, to a predetermined color indicating a selected state, for example, red, to clearly indicate that the display mode is currently in the A mode. You.

Now, on the screen shown in FIG. 2E, the operator operates the pointing device 5 to operate the demand monitoring key 21.
Is selected, the display color of the demand monitoring key 21 is changed from a display color indicating a non-selected state, for example, blue, to a predetermined color indicating a selected state, for example, red. The demand monitoring data as shown in FIG. The operation at this time is as follows. When the position of the cursor of the pointing device 5 is determined, the display control device 2 detects the position of the cursor, and changes the display color of the key displayed at the detected position to a predetermined color indicating a non-selection state, for example, blue, Is changed to a predetermined color indicating the selection state, for example, red. Thus, the display color of the demand monitoring key 21 is changed from blue to red. Next, the display control device 2 determines what data display is requested from the cursor position and the currently displayed screen. in this case,
Since the display control device 2 confirms that the first page of the table of contents is displayed, it can determine that the demand monitoring key 21 has been selected from the detected cursor position. Then, the display control device 2 requests the central control device 1 to transmit demand monitoring data. This is because all the data of the building management is stored in the storage device 6 managed by the central control device 1. The central control device 1 determines a request from the display control device 2, reads demand monitoring data from the storage device 6, and sends the data to the display control device 2. As a result, the display control device 2 replaces the display of the table of contents in FIG. 2E with the demand monitoring data shown in FIG.
Display over the whole of.

When it is desired to confirm other data, for example, a weekly schedule, in the display state shown in FIG. 2 (f), it is necessary to once display a table of contents. It can be done by doing. By this operation, the same operation as described above is performed, the display color of the index key 22 is changed to a predetermined color indicating the selected state, and the display of the area 13 is switched from the demand monitoring data screen to the index screen. Instead, the screen shown in FIG. 2 (e) is displayed. Then, the weekly schedule is selected on the table of contents table, and at the same time the screen of the area 13 is switched from the table of contents to the weekly schedule, the display color of the table of contents key 22 is changed from the color indicating the selected state to the color indicating the original non-selected state. Is done.

The operation of selecting desired data from the table of contents shown in FIG. 2E can also be performed using keys arranged in the area 15. For example, when demand monitoring is selected on the screen shown in FIG. 2 (e), the demand monitoring number is "10". , And then specify the "SET" key 25 to confirm the input number. At this time, the display colors of the "1" key 23, "0" key 24 and "SET" key 25 are changed from the color indicating the non-selected state to the color indicating the selected state. Thereby, the display control device 2
Since it can be confirmed that the display of the data of the number "10" is requested, the data of the demand monitoring shown in FIG. 2 (f) is displayed by the above operation. Then, at the same time when the display of the area 13 is switched to the demand monitoring data, the "1" key 23, the "0" key 24 and the "SET"
The display color of the key 25 is changed from the color indicating the selected state to the color indicating the non-selected state.

As described above, according to the A mode, one piece of data is displayed at the maximum size, so that the data can be clearly checked. Further, the switching operation of the display screen can be performed by operating only the pointing device 5 while observing the screen, so that the operability is good.

Next, the B mode will be described. In the B mode, a reduced image (hereinafter, referred to as a window screen) reduced to 1/4 is superimposed and displayed on one screen on a normal display screen (hereinafter, referred to as a base screen) displayed in the A mode. In the display mode, the display position of the window screen is as shown in FIG.
By selecting the B-mode key of FIG. 3, W ₁ , W ₂ ,
One of the four window positions W ₃ and W ₄ can be arbitrarily selected.

Switching from the A mode to the B mode is performed as follows. Now, as shown in FIG. 3 (b), when data "XX" is displayed in the area 13 in the A mode, the pointing device 5 causes the lower right key of the B mode key to be displayed.
Assuming that 30 is instructed, the display control device 2
Is changed to the color indicating the selected state, and the window set in the area 13 as shown in FIG.
The position of the W _1, and displays the first page of the contents is the initial screen of the window screen. When desired data is selected from the table of contents in this state, the window screen is switched from the table of contents to the screen of the data. When the upper right key 31 of the B mode key is selected on the screen shown in FIG. 3B, the display color of the key 31 is changed to a color indicating the selected state, and the window screen is set in the area 13. is displayed at the position of the window W ₂ it is. Similarly, if the upper left key 32 or the lower left key 33 of the B-mode key in the state shown in FIG. 3 (b) is selected, the position of the window W ₃ or W ₄ each window screen region 13 Is displayed.

In addition, the position of the window screen can be moved to a desired position. That is, as shown in FIG. 3 (e), when the "XX" data is displayed as the base screen and the "VI" data is displayed as the window screen, the upper left key 32 of the B mode key is selected. Then, the display control device 2 changes the display color of the key 32 to the color indicating the selected state, and also changes the key 30 previously displayed in the color indicating the selected state to the color indicating the non-selected state, at the same time as shown in the window screen in FIG. 3 (f), it is moved to the position of the window W ₃ regions 13. As described above, the operation is very simple because the user only has to perform the operation of instructing another B mode key when viewing the screen hidden by the window screen.

Further, in this embodiment, switching between the base screen and the window screen can be performed. The switching key 34 of FIG. 2B is arranged for this purpose.
When the switching key 34 is selected in the state shown in FIG. 3 (c), the display control device 2 reduces the data of "XX" which is the base screen to reduce the window W where the window screen is currently displayed. _The window screen is displayed in a reduced scale at the position ₁ and the window screen is enlarged to be the base screen. The switching key 34 is
When selected, it is displayed in the color indicating the selected state,
At the same time when the switching between the base screen and the window screen is completed, the color is changed again to the color indicating the non-selected state.

As described above, in the B mode, it is possible to simultaneously display two different data screens, but the input operation of the pointing device 5 is enabled only on the window screen. This is because it is possible to make the input operation by the pointing device 5 effective for the base screen, but since the base screen is partially overwritten by the window screen, even if the table of contents is displayed on the base screen, This is because some items of are hidden in the window screen. Therefore, when changing the display of the base screen, the screen of the desired data is first displayed on the window screen, and then the switching key 34 is displayed.
Therefore, an operation for switching the window screen to the base screen is required.

When shifting from the B mode to the A mode, the A mode key 20 may be selected. Regardless of the position of the window screen, if the A mode key 20 is selected, the display control device 2 deletes the window screen and displays only the base screen. At this time, the display control device 2
The display color of the B mode key, which is the display color indicating the selected state, is changed to the color indicating the non-selected state, and the A mode key 20 is changed to the display color indicating the selected state.

Next, the C mode will be described. The C mode is a mode in which window screens can be simultaneously displayed in _four windows W ₁ , W ₂ , W ₃ , W ₄ , respectively, and according to this mode, screens of four types of data can be observed.

The transition from the A mode or the B mode to the C mode is performed by the four C mode keys 40 and 41 shown in FIG.
One of the keys 42 and 43 may be selected. Now, as shown in FIG. 4 (a), the data "XX" is
Key on the upper left of the C mode key when the screen of
When 42 is selected, the display control device 2, and displays the position of the window W ₃ by reducing the base screen to 1/4, of the window screen Other window W _1, W ₂ and W ₄ Initial Display the table of contents that is the screen. At this time, the display control device 2 changes the display color of the A mode key 20 from the color indicating the selected state to the color indicating the non-selected state, and changes the display color of the upper left C mode key 42 to the color indicating the selected state. I do. As described above, when the mode is changed from the A mode to the C mode, the base screen displayed in the A mode is reduced and displayed at the position of the selected C mode key, and the table of contents is displayed in the other windows. It is. Further, in the B mode, when the position of the W _i (i = 1, 2, 3, 4) of the C mode key is instructed, the display control unit 2, by reducing the base screen in the window W _i The window screen is displayed in the same size in the window _Wi-1 , and the other windows display the table of contents, which is the initial screen of the window screen. Note that when W _i is W ₁ is, W _i-1 is the W _4. More specifically, if the upper left key 42 of the C mode key is instructed during the display as shown in FIG. 4C in the B mode, as shown in FIG. it is a screen "XX" is displayed in the window W _3, a window screen "YY" is displayed in the window W _2.

In the C mode, the input operation can be performed by the pointing device 5 only in the window corresponding to the position of the key displayed in the color indicating the selected state, and the input operation cannot be performed in the windows in other positions. It is done as follows. For example, in the state of FIG. 4 described above (b), only the window W ₃ can be input operation.
Thus, in FIG. 4 (b), when selecting a desired menu from the contents displayed in each window W _1, W _2, W ₄ is a C mode key of the desired position by the pointing device 5 To instruct. That is, when it is intended to display a desired screen in the window W ₁ in FIG. 4 (b) indicates the key 40 at the bottom right of the C mode key. With the display control unit 2 to change color to indicate the selection state the display color of the keys 40 by which accepts an input operation for the window W _1, it will not accept the input operation of the other windows. When any input operation is performed on a window in which the input operation is not received, the display control device 2 determines that an erroneous operation has been performed and displays a predetermined alarm in the area 16.

The transition from the C mode to the A mode can be performed by instructing the A mode key 20. At this time, the display control device 2 enlarges the screen displayed in the window that is currently accepting the input operation and displays the screen over the entire area 13. For example, if the A mode key 20 is designated when the window W ₃ in the screen display of FIG. 4 (e) has been made possible input operation, the display control device 2 is displayed on the current window W ₃ Magnify the screen of "XX"
The image is displayed over the entire area 13 as shown in FIG. At this time, it goes without saying that the display color of the A mode key 20 is changed to a color indicating the selected state, and the C mode key displayed in the color indicating the selected state is changed to a color indicating the non-selected state.

To switch from C mode to B mode, use B mode key 30 to
This can be done by designating any of the 33 keys.
Now, when a key corresponding to the position of the window W ₁ of the B-mode key has been instructed, a window display control device 2 is adapted enable input operation on the current C mode, e.g.
The screen displayed on W _j (j = 1,2,3,4) is enlarged and displayed as the base screen, and the screen displayed on window W _j-1 is designated by the B mode key.
To display in the W _i. However, W _j-1 when W _j is W ₁ becomes W _4. Specifically, if the key 30 of the lower right B-mode key is instructed when the window W ₃ in the screen display of FIG. 4 (e) has been made possible input operation, the display controller 2 as shown in FIG. 4 (g), it is displayed in the window W ₃ as a base screen to expand the screen [XX], screen windows W ₁ of "YY" displayed in the window W ₂ To be displayed.

As described above, according to the present invention, there are three types of display modes: A mode for displaying one screen, B mode for displaying two screens simultaneously, and C mode for displaying four screens simultaneously. Since the transition between the B and C modes can be arbitrarily performed whenever necessary, a screen display system with good visibility can be constructed. Further, the operation of selecting a display mode and calling a desired screen can be performed only with a pointing device, so that operability can be improved.

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example, A various deformation | transformation is possible. For example, when shifting from the C mode to the A mode, the window screen to be enlarged and displayed can be selected using the ten keys in the area 15, or the screen displayed in the window at a predetermined position can be enlarged. Can also be displayed. Similarly, when shifting from the C mode to the B mode, the base screen and the window screen in the B mode can be selected by using the ten keys in the area 15, or the window at a predetermined position in the C mode can be selected. May be used as a base screen, and a screen displayed in a window at another predetermined position may be displayed as a window screen.

Also, it is obvious that the present invention can be applied to a building management system of one building, but it can also be applied to a multi-building building management system integrating a plurality of building management systems,
Further, the present invention can be applied to a group management system in which a plurality of multi-building management systems are integrated. An example of the configuration is shown in FIG.

In FIG. 5, control stations 51 and 52 employing the screen display system according to the present invention are disposed in the A building 50. One control station 51 is a sub control station, and the other control station 52 is a main control station. Station and
Each control station is configured to collect data from each facility and issue an instruction to each facility by a loop in the building. However, in FIG. 5, the loop in the building is omitted for the main control station 52. Also, the main control station 52
Is provided with a large-capacity storage device 53. Further, although not shown, the sub control station 51 and the main control station 52 are connected by an appropriate network, and exchange data. The building management system of the A building 50 is configured in this way, but the main control station 52 is connected to other terminal devices via the local area network LAN 56,
Any terminal device connected to the LAN 56 can access the building management system.

A control station employing the screen display system according to the present invention is disposed in the B building 54, and a building management system of the B building 54 is configured. The building management system of the C building 57 is the same as the building management system of the A building 50, and includes a main control station 58 and a sub control station 59.

The management of each building is performed by such a configuration, and the management system of each building is connected by an in-site loop 60, thereby forming a multi-building management system. And the multi-building management system is a public line
61 is connected to other multi-building management systems to form a group management system.

In such a large-sized system, the operability and visibility of the user interface are particularly important. However, according to the screen display method according to the present invention, the visibility and operability are good as described above. Therefore, when adopted in the system as shown in FIG. 5, the operation of the system can be performed efficiently.

As described above, the screen display method according to the present invention is suitable for a building management system, but it is needless to say that it can be similarly applied to other computer systems and the like.
