Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a display device suitable for displaying information input from an external device on a display in real time.

[0002]

2. Description of the Related Art For example, a device for monitoring various systems is provided with a display device for displaying various information so that an administrator can recognize the state of the system. The display device displays, in addition to the operation state of the system, the type of the failure, the location where the failure has occurred, and the like when any failure has occurred. When the information supplied to the display device exceeds the displayable amount of the display device, the information is usually scrolled on the display screen. If the scroll speed is too fast, the administrator cannot read the contents, so the scroll speed and the like are appropriately adjusted.

[0003]

However, the above-mentioned conventional display devices have the following problems to be solved. When various types of information are input to the display device, the administrator who monitors the state of the system examines these contents and takes necessary measures. If the information contains urgent trouble information, the necessary action must be taken immediately. However, if a large amount of information is decrypted while scrolling in order, it takes a long time to read the contents even when highly urgent information is continuously input, and there is a problem that prompt response cannot be performed.
However, if the scroll speed is increased, there is also a problem that the content of the displayed information cannot be sufficiently grasped and an appropriate response cannot be taken.

[0004]

The present invention employs the following structure to solve the above problems. <Configuration 1> A display for displaying input information transferred from an external device, and a display control unit for controlling display contents of the display, wherein the display has a main display area for displaying first input information, A sub-display area for displaying a part of the second input information input after the first input information, the sub-display area being sufficiently smaller than the main display area; Wherein the second input information is scrolled in the sub display area while the first input information is being displayed.

<Explanation> The display may be a display device of any configuration having a screen for displaying information such as characters. The first input information is displayed in the main display area. On the other hand, the second input information input after that cannot be displayed in the main display area until the operator finishes reading the first input information, for example, and is displayed in the sub display area. Since the sub display area is an area that is sufficiently smaller than the main display area, the entire second input information cannot be normally displayed. Therefore, a part of the second input information is displayed and scrolled. The second input information may be completely different from the first input information, or may be related information to be input subsequent to the first input information. This allows the operator to change the first displayed on the main display area.
It is possible to know that there is other input information in addition to the input information. Moreover, the operation of reading the first input information is not hindered by the input of the second input information.

<Structure 2> In structure 1, when the second input information is displayed in the sub-display area and scrolled, the scroll speed is predicted when viewed with the naked eye. A display device characterized by selecting a speed that can be achieved.

<Explanation> Even if the second input information is scrolled at a high speed, the operator can recognize only that the second input information exists following the first input information. But,
By scrolling slowly to some extent, for example, in the case of an emergency report, the operator can recognize the keyword and take necessary measures. In addition, if the keyword is displayed in color, even if scrolling a little faster, its existence can be recognized and its content can be predicted. In this case, the prediction in this case may be a rough prediction, and may not be such that accurate contents can be predicted.

<Structure 3> The display device according to Structure 1, wherein the second input information is a portion of the first input information that follows the first input information that cannot be displayed on the main display screen.

<Explanation> The second input information may be a portion of the first input information that cannot be displayed in the main display area. In this case, since the first input information is displayed in the main display area and an overflow is displayed in the sub display area, the information displayed in the main display area does not have to be scrolled, so that there is an effect that it is easy to see.

<Structure 4> A display for displaying input information transferred from an external device and a display control unit for controlling display contents of the display are provided. The display displays the first input information and A display device for notifying the presence of second input information input after the first input information and including a warning display.

<Explanation> The warning display includes an appropriate message, a display such as a character such as a symbol or a picture. The display position is free. Further, a warning may be accompanied.

The device shown in the figure comprises a reception buffer 2 for receiving information to be displayed from an external device 1, a display control unit 3, and a display 4, as shown in the figure. The information received by the reception buffer 2 is controlled by the display control unit 3 and displayed on the display 4. The external device 1 collects, for example, system failure information,
It is composed of a device for collecting various other information from the whole system.

The display control unit 3 includes a control circuit 5,
A fixed module 6, a variable module 7, and a display information assembling module 8 are provided. Control circuit 5
Is a circuit for controlling the data transfer direction so that a part of the information stored in the reception buffer 2 is sent to the fixed module 6 and the rest is sent to the variable module 7 as described later. The fixed module 6 and the variable module 7
This is a memory for temporarily storing characters to be displayed on the display 4 and other information. The display 4
In the present invention, the display area is divided into a main display area D1 and a sub display area D2. In the main display area D1, various types of information whose contents should be decoded by the administrator are displayed. The sub display area D2 is newly provided in the present invention, and the main display area D2 is provided.
This is a portion for scrolling and displaying information to be input subsequent to the information displayed in 1.

FIG. 2 shows a block diagram of the control circuit. The control circuit 5 includes a fixed module display status storage circuit 11, a determination circuit 12, and a switch 13 for distributing information to the fixed module 6 and the variable module 7. The fixed module display status storage circuit 11 stores information such as which input information is stored in the fixed module 6 and whether the fixed module 6 is cleared. The determination circuit 12 is a circuit that switches the direction of the switch 13. For example, new determination information input from the input terminal 13 </ b> A of the switch 13 is
It is composed of a register or the like for storing data for distinguishing the case of transferring to the fixed module 6 and the case of transferring to the variable module 7. Input terminal 13A of switch 13
Are connected to the reception buffer 2 shown in FIG. 1, and the corresponding information is transferred from the reception buffer 2 to, for example, the fixed module 6.

The display information assembling on the specific display is performed by the display information assembling module 8 shown in FIG.
Done by FIG. 3 is a schematic explanatory diagram of display control by the device of the present invention. In the apparatus of the present invention, for example, when the input information 15 as shown in FIG.
Is divided into the first input information 15A and the second input information 15B. The first input information 15A is information of an amount that can be displayed in the main display area D1 of the display 4. On the other hand, the second
Is the remaining information, which is scroll-displayed in the sub-display area D2. This sub display area D2
Is set to, for example, several lines, that is, about 2 to 3 lines.
The rest is the main display area D1 to enable sufficient display of necessary information.

Then, first, the first input information 15A is displayed as a still image in the main display area D1. When the administrator finishes analyzing the content of the first input information in this way, for example, the display of the first input information is canceled. As a result, the second input information 15B becomes the first input information 15A, and the main display area D
1 will be displayed. On the other hand, the first input information 15
While displaying A in the main display area D1, the administrator does not know whether or not the second input information 15B following the first input information exists. However, when this is scroll-displayed in the sub-display area D2, its existence and approximate amount can be predicted.

Further, for example, it is assumed that the second input information is a document that uses green characters for ordinary non-urgent information and red characters for highly urgent characters. At this time, when the first input information is input to the main display area D1 and the second input information is scroll-displayed in the sub-display area D2, an easily visible portion such as a red character is scrolled. And its existence can be recognized. As a result, the administrator knows that highly urgent information is included in the second input information 15B. Therefore, for example, the decoding of the first input information 15A is postponed, the second input information is displayed in the main display area D1, and the processing of information with high urgency can be performed first.

The above is the outline of the present invention, and a more detailed operation of the apparatus of the present invention will be described with reference to FIG. FIG.
4 is an operation flowchart of the device of the present invention. When information is received from an external circuit in step S1 in the figure, the display information assembling module 8 shown in FIG. 1 refers to a display row in the main display area in step S2. This is, for example, the fixed module display status storage circuit 11 shown in FIG.
Is stored in Then, in step S3, it is determined whether new information can be displayed in the information input to the main display area. When nothing is displayed in the main display area, display can be performed in the main display area. If the first input information is already displayed in the main display area, it is determined that the display cannot be performed.

If the display is possible, the process proceeds to step S4, where the input information is transferred to the fixed module 6. That is, this is treated as the first input information. Then, in step S5, the content is displayed as a still image in the main display area D1 shown in FIG. On the other hand, if it is determined in step S3 that display is not possible, the process proceeds to step S6, and the input information is transferred to the variable module 7. Then, the information read from the variable module 7 is scroll-displayed on the sub-display area D2 of the display 4. It is checked in step S8 whether such a determination has been made for all input information. If there is any remaining information, the process returns to step S1. Such processing is executed for each line of the input information or for each appropriate amount of the input information, and the display of the information is controlled at a predetermined position on the display by using the fixed module 6 or the variable module 7.

FIG. 5 is a block diagram showing a modification of the present invention. In this modification, all the information that can be displayed on the display 4 among the input information is transferred to the fixed module 6 and displayed. On the other hand, if there is subsequent information that cannot be displayed on the display 4, the control circuit 5 displays a warning mark 18 on the display 4.
Is displayed. The mark 18 may be a letter or a symbol and may have any suitable shape. As a result, the administrator recognizes that subsequent information exists and, for example, when urgent information exists, displaying that fact also enables quicker response.

That is, in this specific example, instead of displaying the succeeding information on the display as it is, the fact that the succeeding information exists and the fact that the emergency information is included in the information are displayed to the administrator so that the subsequent information is displayed. Attention should be given to considering the handling of information that In addition, the presence or absence of such information may be notified by sound using the speaker 17 shown in the figure. In addition, a display device other than a lamp and other displays may be used.

The control circuit 5 may be constituted by hardware or software. The control circuit 5 is capable of receiving information in a reception buffer and displaying information for display on a display. Any type can be used as long as it can be divided into an overflow and processed.
