Abstract

PURPOSE:To improve the processing efficiency, by transmitting a control output to a distributor through an interface and visualizing a part of each picture when the same data from the distributor is displayed on plural CRTs for decreasing the amount of hardware. CONSTITUTION:A controller 1 is connected to the distributor 4 via the interface 2 and the CRTs 31, 32-3n are connected to the distributor 4. The same display data transmitted from the controller 1 come to and are displayed on the CRTs 31, 32-3n with the matching of the distributor 4. Further, a visualizing device visualizing a part of picture in the same picture is added to the CRTs 31, 32-3n. This device displays only a required picture for a viewer observing the device by sticking a masking tape 6 on a CRT screen 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display system that is most suitable for use when presenting work instructions and the like to a plurality of workers.

[Technical background of the invention]

In the conventional building system, as shown in FIG. □+"'--+2n. Then, when the controller 1 is looking at the CRT display devices 34, 3□+--1+3n, for example, when giving work instructions to each worker, the controller 1 is looking at the CRT display devices 34, 3□+--1+3n. □＋ −−
-+3n is selected according to its own program, and is sequentially sent out via the interfaces 21, 2□+---4n, for example. With this, j2, CRT display panel 3□, 3□+----+
31 displays work instructions suitable for the work to be performed by each worker, and the workers perform the work based on these.

[Problems with weight technology]

However, as is clear from the figure, such a conventional system requires a number of interfaces corresponding to the number of CRT display devices, resulting in a complicated hardware configuration. Further, even if the items displayed on the CRT display device are, for example, about one line for each CRT display device, and all the items fit on one screen, the controller 1 controls the valley CRT display device. It was an inefficient system as it required a lot of processing.

[Purpose of the invention]

The present invention has been devised in view of the drawbacks of the conventional systems as described above, and its purpose is to reduce the amount of hardware and provide an efficient display system.

[Summary of the invention]

Therefore, in the present invention, one controller, an interface connected to this controller, a distributor connected to this interface for sending display data outputted by the controller in multiple directions, and a controller connected to this distributor are provided. A display device that displays the same image regarding the same display data sent from the controller via the distributor and the interface, and a highlighting means that makes a part of the image noticeable and presents it to the viewer. A display system was constructed with multiple display devices to which .

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram of an embodiment of the system of the present invention.

In the figure, a controller 1 is connected to a distributor 4 via an interface 2. This distributor 4 has CR
T display device (display device) 31+3□, ---,
3n is connected. Here, interface 2 is the first
Interface 2, in figure.

It has the same configuration as 2□, ---, and 2n. Further, the distributor 4 sends display data (for example, character code) sent from the controller 1 via the interface 2 to the CRT display devices 31, 3□.

---, 3n, and by the matching action of the distributor 4, the same display data sent from the controller 1 is sent to the CRT display devices 30, 3□+----+3n. The same image can be displayed on the CRT display device 3t+32+---+3n.

Also, although not shown in this figure, the CRT display devices 31, 3□, ---3n include a highlighting means for making a part of the above-mentioned same image noticeable and presenting it to the viewer. added.

Here, the highlighting means will be explained. As mentioned above, the highlighting means indicates to the viewer the part that he/she should look at, so an example of this means is a CRT as shown in FIG.
There is a masking tape 6 stuck on the screen 5. For example, this masking tape 6 may be used to leave only the part where the characters on the first line of the screen of the CRT display device 31 are displayed, masking the rest, and display the characters on the second line of the screen of the CRT display device 32. It is used to show only the necessary images to the person using the CRT display device, by leaving out only the areas that will be displayed and masking the rest. Alternatively, the masking tape may be colored and semi-transparent, and the semi-transparent part may be used as the part of the image that should be shown.

FIG. 4 shows the highlighting means with a partially transparent nozzle 7.
The panel 7 is lid-shaped, and screws 9 are provided at predetermined locations on the peripheral edge 8. For example, the CRT screen 5 can be pressed with the screws 9 from the top, bottom, left, and right to hold the panel 7. It has become. Also, part of the front part 1 (J) of the panel 7 is a transparent part 11, and the other part is opaque.Whether this is transparent or opaque depends on whether the panel 7 itself is made of colored plastic or You can use masking tape or paint it with color.

FIG. 5 shows the highlighting means in an opaque horizontal panel 71.7.
Panel 7I consists of □, ---1.

The left end of 7□, --- is the hinge 12. , 12□, -1- are connected to the collection frame] 3, and the right end is a free end, which can be opened and closed as shown in the figure. That's sweet, panel 7.
A limit switch 14. , 14□, -m- are provided. When the panel 71 is opened as shown in the figure, the limit switch 14 is turned on and is connected to the controller 1 in FIG. 2 via a signal line (not shown).

If this is illustrated in blocks, as shown in Figure 6,
When any of the limit switches 141 r 142 + --- is closed, this signal is taken into the controller 1 via the interface 15. As a result, for example, since the top panel 71 of the CRT display device 3 is open, the controller 1 causes the CRT display device 3 to display work instructions with a fixed hourly rate at predetermined time intervals. You can also.

In the system configured in this manner, the controller 1 includes the CRT display devices 31, 3□.

--- Display data to display the same image is sent to +31, but CRT display devices 3□, 3□.

---+ In 3n, only a certain part of the image is provided to the viewer by the highlighting means. Therefore, when this system is used for work instructions, it is possible to display work peaks and valleys to the person performing the work, just as in the conventional system.

In addition, even if the controller changes some of the displays, 1
The display data may be sent for each screen, or only the display data that needs to be changed may be sent and the display of that portion may be changed.

〔Effect of the invention〕

As described above, according to the present invention, only one interface is required and the amount of hardware can be reduced.

Best of all, the parts you want to display can be viewed separately on each display device, and accurate instructions can be given.

Moreover, since the controller is equivalent to sending display data to one display device, the processing efficiency of the controller is good and the system as a whole is also excellent.
