Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor / control console having a graphic panel, which is used for centralized monitoring in power receiving / transforming systems, air conditioning systems, water supply / drainage systems, disaster prevention / crime prevention systems and the like.

[0002]

2. Description of the Related Art A monitor / control console is a centrally installed device for performing centralized monitoring and automatic control of a system. It is possible to display the operation of each device, the operating state of the system, and the location of the failure in an easy-to-understand manner by arranging classes.

A graphic panel is used as a means for performing the display. In the configuration of this graphic panel, conventionally, as shown in FIG. 7, a panel 92 is provided on the front surface of a table main body 91, and an indicator lamp (tube indicator lamp or LED indicator lamp) 93 is attached to the panel 92. Then, in order to display the failure name on the side of the indicator light, a method of adhering the dial 94 to the panel or performing silk printing directly on the panel has been adopted.

[0004]

However, in the conventional graphic panel as described above, when the display specification (for example, the number of indicator lights) is changed, the number and arrangement of the indicator lights are changed. It was a big task because I had to remove the entire panel and replace the indicator lamps with a new array of graphic panels.

Further, even when the display contents are changed with the arrangement of the indicator lights unchanged, it takes time and effort to go around the narrow space behind the monitor and control console and change the wiring. At this time, if silk printing had been performed, the entire graphic panel had to be replaced with a newly printed one. In addition, daily maintenance and inspections other than changing the specifications had to be carried out in a narrow space behind the monitor / control console, which was a difficult task.

Further, in the structure of the conventional graphic panel, the indicator light is projected from the panel surface, so that the appearance is not neat. Therefore, an object of the present invention is to solve the above-mentioned technical problems and to provide a graphic panel of a monitor control console with a neat appearance, which can be easily dealt with in the case of a specification change or maintenance inspection.

[0007]

A graphic panel for a monitor and control console according to claim 1 for achieving the above object comprises a display light mounting substrate, a mounting frame, a surface plate,
A graphic panel having an inner plate is removably attached to the main body of the monitor and control console, and a plurality of indicator lights are mounted on one surface of the indicator light mounting board so that the light emitting surfaces are arranged on the same plane. In the mounting frame, the indicator light mounting board and the transparent or translucent surface plate are attached and detached with the light emitting surface of the indicator light mounting board facing the surface plate from opposite sides of the mounting frame. The inner plate is sandwiched and fixed in a non-adhesive state between the surface plate attached to the mounting frame and the light emitting surface of the indicator light mounting board, and the inner plate is attached to the light corresponding to the indicator light. A mark indicating the display content is attached, the transmittance of which is different from the light transmittance of the ground of the inner plate.

In the graphic panel according to the second aspect, the inner plate is divided into a plurality of plates.

[0009]

According to the above construction, when the specifications are changed, the graphic panel is removed from the main body of the monitor and control console, and the indicator light mounting board and the surface plate are removed from the mounting frame. And
In addition to replacing the indicator light mounting board and wiring, replace the inner plate that was interposed between the surface plate and the light emitting surface of the indicator light mounting board with a new mark, and in reverse order again. Assemble the graphic panel.

After the graphic panel is assembled, the light emitted from the light emitting surface of the indicator light mounting substrate can be seen through the inner plate and the front plate. In this case, since a mark indicating the changed display content is attached to a portion of the inner plate corresponding to the indicator light, it can be used as a graphic panel with new specifications.

When the inner plate is divided into a plurality of plates as in the graphic panel according to the second aspect, if the specification is changed, only the plate to be changed may be replaced.

Embodiments will be described in detail below with reference to the accompanying drawings showing embodiments. FIG. 2 is a perspective view showing an outline of the monitor control console 1 using the graphic panel of the present invention, and shows that the graphic panel 2 is removable. 1 is a vertical sectional view of the graphic panel, and FIG. 3 is FIG.
FIG. 9 is a cross-sectional view of the graphic panel taken along the line A-A of FIG.

Referring to FIG. 1, the upper and lower mounting frames 12a.
Is a square frame 1 for framing the graphic panel
It is a metal fitting having an L-shaped cross section, which is fixed to 5 by screws 16.
A packing 17 serving as a frame for supporting the inner plate 14 is adhered to the front surface of the upper and lower mounting frame 12a. Further, the LED mounting board 11 is mounted on the rear surface of the upper and lower mounting frames 12a by screws. The LED mounting board 11 has a plurality of LEDs 19a, 19b, ...
.., 19n are mounted so that the flat light emitting surfaces are arranged on the same plane.

The LEDs 19a, 19b, ..., 1
The inner plate 14 is in contact with the 9n light emitting surface,
It is clamped and fixed in a non-adhesive state. Further, the inner plate 14 is covered with a blackish semi-transparent surface plate 13 such as an acrylic plate in contact therewith. The surface plate 13 is silk-printed (opaque) on a black background from the backside except for the portions corresponding to the light emitting surfaces of the LEDs 19a, 19b, ..., 19n.

The surface plate 13 is a left and right mounting frame 12a fixed to the right and left sides of the rectangular frame 15 with screws 18.
On the other hand, it is fixed by a screw 20 (see FIG. 3). Therefore, the surface plate 13 and the LED mounting board 11 are mounted from the opposite sides of the upper and lower mounting frames 12 a so that the light emitting surface of the LED mounting board 11 is the front surface via the inner plate 14.

The inner plate 14 is an opaque acrylic plate on which a black background is silk-printed, and as shown in FIG. 4, only the character portion representing the display content is transparent at the portion corresponding to the LED (FIG. 4). Then, the letters look opaque, but actually the inner plate 14 is black and the letters are transparent). FIG. 5 is an exploded perspective view of a main part of the graphic panel, showing a state in which the inner plate 14 is applied from the front surface to the upper and lower mounting frames 12a to which the LED mounting substrate 11 is mounted, and the surface plate 13 is brought into contact therewith. ..

According to the configuration of the graphic panel,
When the LED of the LED mounting board 11 does not emit light, nothing can be seen because of the black inner plate 14, but the predetermined L
When light is emitted from the ED, the characters on the inner plate 14 corresponding to the LEDs transmit the light, so that the characters floating on the light on the surface plate 13 can be read (see FIG. 6).

Since the surface plate 13 is adopted in this manner, it is possible to produce a neat appearance without any protrusion on the surface. Also, if there is a change in specifications, remove the graphic panel from the monitor control console body,
Loosen the screws and the LED mounting board 11 and the surface plate 13
Is removed from the upper and lower mounting frames 12a. Then, the LED mounting board 11 is replaced and the wiring is replaced, and among the inner plates 14 interposed between the surface plate 13 and the LED light emitting surface, only the changed one is replaced with a new one, and the reverse operation is performed again. Assemble the graphic panels in order.

Therefore, since the graphic panel can be removed from the main body of the monitor and control console, the LED mounting board 11 can be easily replaced and the wiring can be changed, and a new inner plate 14 can be prepared corresponding to the specification change, and only the old one can be replaced. It's done. In this respect, in the past, compared to removing the entire large graphic panel and replacing the indicator light with a new graphic panel arranged newly,
The work will be greatly simplified.

Further, even when the monitor / control console is produced in a factory, there is an advantage that only the LED mounting substrate 11 and the inner plate 14 are prepared according to the specifications, and the remaining parts can be shared. Further, since the graphic panel can be detached from the main body of the monitor / control console during maintenance and inspection, it is not necessary to go around the graphic panel for maintenance as in the conventional case, and the work is facilitated.

The present invention is not limited to the above embodiment. Although the LED mounting substrate 11 is used in the above embodiment, an EL (electroluminescence) light emitting element or the like may be used instead of the LED. Also surface plate 1
3 may be transparent, and the inner plate 14 may be wholly transparent so that only the character portion representing the display content is opaque. Other various changes can be made without changing the gist of the present invention.

[0022]

As described above, since the graphic panel of the supervisory control console according to claim 1 can be detached from the main body of the supervisory control console, it is necessary to go around the narrow space behind the supervisory control console for daily maintenance and inspection. In addition to disappearing, when changing the specifications of the graphic panel, the indicator light mounting board is replaced and the wiring etc. are changed, and the inner plate interposed between the surface plate and the light emitting surface of the indicator light mounting board is changed to a new one. Since it is only necessary to replace and assemble the graphic panel again, there is no need to replace the entire large graphic panel, which saves resources and facilitates the changing work.

Further, since the surface plate is used, the surface of the graphic panel can be made a flat surface without any unevenness. According to the second aspect of the invention, since the inner plate is divided into a plurality of plates, when the specification of the graphic panel is changed, only the inner plate of the changed portion needs to be replaced with a new one. The change work can be further simplified.
