Abstract

PURPOSE:To reduce the cost and to save the space with a picture display system of a computer system, by displaying selectively the picture information given from a computer and the video information given from a TV camera to at least one CRT monitor. CONSTITUTION:A fault at a certain area of a control system is detected from the information projected to the 1st or 2nd CRT monitors 11a and 11b. In such a case, the video obtained by ITV cameras 8 and 9 set at the faulty area are switched automatically or manually to a display screen of the monitor 11a or 11b. The screen information profected to the monitor 11a or 11b can be selected by actuating a switch 10 with the commands given from computers 1 and 2 or a command from a keyboard 11c. For the cameras 8 and 9, the optical axes of lenses can be moved vertically and horizontally by means of a joy stick 11d of a control board 11. Furthermore a zooming action is also possible for the lens by means of a lever 11e.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a computer equipped with a plurality of electronic thickeners connected to a common control panel and a television camera for monitoring a controlled object. This invention relates to an image display method in a computer system such as the A7 system.

[Technical background of the invention]

This type of one-computer control system using a conventional control panel was constructed as shown in Figure 181.

In Figure 1, %7#'1IIl calculator, 2 is the second
, 11 is the DMA (direct memory access) path of the first ti calculator 1, and B2 is the D of the second ti calculator 2.
MA pass, 3 is display switch, 4 is industrial telephoto camera (
(hereinafter referred to as "ITV camera"), 51 control panel, 5h a car (cathode ray tube) monitor built into the control panel 5, 5
b is an ITV monitor consisting of a CRT for displaying ITV images, and Me is a key node attached to the control panel 5 OCRT monitor 5a.

Normally, the CRT monitor s1 is connected to the first one via the display switch 3.
It is selectively connected to the E computer I and the second computer 2. The switching control input of this display switching device 3 is given from the 11th@2 total W machine 2t or the key gate 5c.

That is, the CRT monitor 5m#'i is used to display characters or graphics based on information from the first computer or the second computer 2, and to display sounds.

In front of the control panel 5, there is an ITV for monitoring the controlled objects.
A monitor 5b is incorporated, and images from an ITV camera 4 installed at a monitoring location are displayed on the ITV monitor 5bK.

[Problems with background technology]

However, in such a case, the CRT monitor 5a and I
Although the two CRT displays of the TV monitor 5b are provided, the CRT monitor 5a is used only for displaying graphics, and the characters calculated by Wkiez are used only for graphic display.
The TV monitor 5b is used exclusively for displaying surveillance video information of the I'Iv camera 4. Generally, the monitoring video information sent from the ITV camera 4 does not need to be constantly monitored, and is often needed only when an abnormality occurs.

In addition, it is often necessary to frequently monitor both the character or graphic display information from the computers 1 and 2, and in such cases, the key gate 5@1i
The display information on the CRT monitor 5a must be changed by operating the CRT monitor 5a. In this way, the CRT display installed in the control panel 5 is inconvenient in that one side displays unnecessary information or is in a non-display state, while the other displays multiple pieces of display information by rapidly switching between them. A circle is formed.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an image display method that can improve the efficiency of displaying image input, eliminate waste in the display device, reduce the cost of the device, and save space for the control panel, etc.

[Summary of the invention]

The present invention provides an image display method in a computer system equipped with a computer and a television camera for monitoring, in which screen information from the needle 'I#' and video information from the television camera are displayed on at least one CRT monitor. It is characterized by selective display.

[Embodiments of the invention]

#i Figure 42 shows the system configuration of an embodiment of the present invention.
((show.

In FIG. 2, the same parts as those in FIG. 6 and 7 are the first
and a display control unit that converts the information output from the second computers I and 2 to the DMA paths B1 and B2 into display signals; 8 and 9 are the ITV outputs of the first and 12;
Character/Graphics from Fi Display Control 6.7.

1] is a control panel, and 11a and Ilb are computers 1 and 1 that are selected by the video signal switch 10;
11c is the key for input operation &-1-", 11d is the FiITV camera 5.
II, 9 is a joystick to move up and down, left and right by remote control, ri, 11 is ITV camera 8
, 9 is a lever for zoom control of the lenses.

Next, the operation in the KS$112 diagram will be explained.

For example, the first CRT monitor I1m always displays one-page information from the first computer 1, and the second CRT monitor
In b, one-page information from the rm20 calculator 2 is displayed. Or vice versa.

If it is determined from the information displayed on the first CRT monitor 111 or the second CRT monitor l1bK that an abnormality has occurred in a certain part of the control system, the system is automatically or manually installed at that part. One CRT monitor (11at only 1
lb) Switch the C1 display lji plane.

To select the screen information to be displayed on the CRT monitor 1c or llb, a command from the computers 1 and 2 or a command from the key Ilc is given to the video signal switch 10.
This can be done by operating 0.

The ITV cameras 8 and 9 can move the light up and down and left and right by means of the optical stick Ild built into the control panel 11, and can also zoom the lenses by means of the lever 11.

In this way, by switching and displaying the screen information from the computers 1 and 2 and the images from the ITV cameras 8 and 9 on the CRT monitor 11* and Ilb, the following effects can be expected.

0) Cost can be reduced because the number of monitors can be reduced.

(B) (B) It is possible to downsize the control f1111 in practice.

Furthermore, in this case, since the ITV cameras 8 and 9 can be controlled by remote control, this is particularly effective when the ITV cameras are installed in a place where humans cannot enter (for example, around a nuclear reactor).

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be modified in various ways to converge flows without changing the gist thereof.

For example, in the above embodiment, a CRT monitor built into a control panel has been described, but this concept can also be applied to a general CRT monitor connected to a computer.

In other words, in a general-purpose computer system, a CRT monitor connected to the computer is installed in a security room, etc., and the block diagram of the computer system is usually displayed on it. When an abnormality occurs, it may be possible to switch to images from television cameras in the vicinity.

〔Effect of the invention〕

According to the present invention, it is possible to improve the efficiency of displaying image input, eliminate unnecessary display devices, lower the cost of the device, and save on control panels, etc.
It is possible to provide an image display method that can realize
