Abstract

PURPOSE:To prevent a CRT screen from being burnt due to the long unvaried state of display contents by providing the title monitoring device with an automatic picture control part and a display picture table state monitoring part. CONSTITUTION:When a monitor does not operate a keyboard 4 within an optional time, the automatic picture control part 7 sends display control information 9 through a keyboard interface part 3 to automatically select the display screen of a central processing part 5. The processing part 5 displays the selected picture information on a CRT display part 1 through a CRT control part 2. When fault information is inputted to the processing part 5 through an external interface part 6, a state transition monitoring part 10 selects a corresponding display picture number and sends the selected picture information to the interface 3 through the control part 7 and the display control information 9 is stored until the operation of the keyboard 4. Since the display contents of the CRT are switched at a fixed interval when the keyboard is not operated for a fixed period in said constitution, and if an external fault is generated, the state is instantaneously displayed and stored, the life of the CRT can be extended.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to CRTs used in computer systems, etc.
The present invention relates to a monitoring device having a display section.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 2, this type of monitoring device has been configured to display a display screen table stored in a central processing section 24 based on information input from an external connection device via an external interface section 25. is updated in the central processing unit 24 and sent to the CRT control unit 21 as display screen table information.

The CRT control unit 21 converts the display screen table information sent from the central processing unit 24 into display information 26, and converts it into display information 26.
It is sent to the R7 display section 20.

The contents of the display information 26 are displayed on the CR7 display section 20,
It becomes possible to monitor the status of computer systems, etc.

Further, the central processing unit 24 is provided with a plurality of display screen tables, and the user can select the display screen table that he or she wishes to display using the keyboard 23.

Problems to be Solved by the Invention However, the above-mentioned conventional monitoring device does not display CR unless the monitor performs a screen switching operation from the keyboard.
The CR1 screen may be burnt out because the display contents of the T display (for example, the configuration screen of the Funpy computer system) do not change for a long time.
However, there was a drawback that the life of the CRT display section was shortened.

In addition, when there is a failure etc. in an externally connected device and you want to immediately check its status, if the details of the problem etc. in the externally connected device correspond to a display screen table other than the screen currently displayed, There was a drawback that the display screen could not be viewed unless it was selected using the keyboard.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new monitoring device which makes it possible to overcome the above-mentioned drawbacks inherent in the prior art.

Means for Solving the Problems In order to achieve the above object, the monitoring device according to the present invention has the following features:
CR1 display section, keyboard interface section, keyboard, central processing section, external interface, automatic screen control section for automatically switching display screens, and state transition monitoring section that monitors the state of the display screen table provided in the central processing section. have.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, the central processing unit 5
updates the display screen table and sends it to the CRT control section 2 as display screen table information.

The CRT control unit 2 converts the display screen table information sent from the central processing unit 5 into display information 8 and displays it in CR1.
It is sent to the display section 1.

The contents of the display information 8 are displayed on the CR1 display unit 1, and the status of the computer system etc. can be monitored.

Further, the central processing unit 5 is provided with a plurality of display screen tables, which the observer can freely select by operating the keyboard 4.

On the other hand, when the observer does not operate the keyboard 4 within an arbitrarily set time, the automatic screen control unit 7 automatically selects the display screen table included in the central processing unit 5 and switches the display screen at regular intervals. A signal for this purpose is sent to the keyboard interface unit 3 as display control information 9. The keyboard interface section 3 converts the display control information 9 into a screen selection signal and sends it to the central processing section 5.

The central processing section 5 sends the display screen table information selected by the display control information 9 to the CRT control section 2.

The CRT control unit 2 converts the display screen table information into display information 8.
and sends it to the CR1 display section 1.

As described above, the contents of the display information 8 are displayed on the CR1 display section 1.

Further, when a failure or the like occurs in an externally connected device and the information is input to the central processing unit 5 via the external interface unit 6, the state transition monitoring unit IO monitors the display screen of the display screen table where the state transition occurred. A number is selected and sent to the automatic screen control section 7 as selection screen information 11.

The automatic screen control section 7 sets a display screen number based on the selection screen information II, and sends it to the keyboard interface section 3 as a display control report 9. At this time, the display control information 9 is held until the observer operates the keyboard 4.

The keyboard interface unit 3 displays the display control information 9
is converted into a screen selection signal and sent to the central processing unit 5. Thereafter, operations similar to those described above are performed until the CR1 display unit 1 displays the display screen when there is a failure or the like in the external connection device.

In other words, when the supervisor does not operate the keyboard 4 for a certain period of time, the display content on the CR1 display section 1 changes at regular intervals, and if there is a problem with an externally connected device, the status is immediately displayed. will be retained.

As described in detail, according to the present invention, when the supervisor does not operate the keyboard of the monitoring device for a certain period of time, the display screen of the CR1 display section changes at regular intervals, and the display screen of the external connection device changes. If the display contents of the CR1 display section do not change for a long period of time due to a failure, etc., and the corresponding display screen is forcibly selected and displayed, the CRTiij surface may be burnt out and the
This eliminates the disadvantage of shortening the lifespan of the RT display unit, and also provides the advantage of being able to immediately see the status of an externally connected device, such as a failure.
