Description

  The present invention relates to a display control system for a display device such as a liquid crystal display attached to a switchboard for monitoring the switchboard.

In recent years, cases for attaching a display device such as a liquid crystal display on the switchboard have been increasing for monitoring the switchboard.
In FIG. 2, the perspective view which shows schematic structure of the conventional switchboard is shown.
As shown in FIG. 2, the liquid crystal display 20 of the switchboard 30 is attached to a place where an operator or the like can easily see.

The conventional liquid crystal display 20 for monitoring the switchboard 30 extends the life of the liquid crystal display 20 and, from the viewpoint of power saving, normally the power is turned off and nothing is displayed.
On the other hand, when an operator or the like touches the screen of the liquid crystal display 20, the monitoring information of the switchboard 30 is displayed on the screen.

JP 2003-346993 A

By the way, as described above, the liquid crystal display of the conventional switchboard usually has a merit of extending the life of the liquid crystal display and saving power because nothing is displayed because the power is normally turned off.
However, on the other hand, since the operator cannot operate the switchboard without touching the liquid crystal display at any time while operating the switchboard, there is a problem that work efficiency is lowered.

  In particular, when working while looking at the display on the liquid crystal display at a location away from the switchboard, each time the display disappears, you must move to the switchboard by touching the screen so that the liquid crystal display is always displayed. There is also a request from the user side.

  However, on the other hand, if the liquid crystal display is always displayed, it is not preferable from the viewpoint of the life of the liquid crystal display and power saving if the power supply is forgotten to be turned off.

As a countermeasure, an outlet tap that automatically distributes power to an electrical product has been developed as in the invention described in Patent Document 1.
This outlet tap will be described with reference to FIG.
FIG. 3 is an external perspective view of a conventional outlet tap that performs automatic power distribution.

  The outlet tap 100 includes an electric lock 115 provided on the door and a plurality of outlets 112a to 112d whose power on / off state is switched by an unlocking / locking signal of the electric lock 115. A display showing the status is made.

However, this conventional system for automatic power distribution has a problem that the entire distribution board is turned off by the lock signal of the electric lock 115.
Also, from the viewpoint of operator workability, it is difficult to satisfy the requirement to turn on / off the liquid crystal display only when the operator needs it.

  The present invention solves the above-mentioned problems (problems), and provides a screen display control system for a display device of a switchboard capable of greatly improving workability with an extremely simple configuration, and saving power and extending the service life. Objective.

  The screen display control system of the switchboard display device according to the present invention comprises the switchboard display device and the switch of the switchboard display device installed at a desired location. It was.

  A screen display control system for a switchboard display device according to claim 2, wherein the switchboard display device, a lighting switch installed at a desired location, and an ON / OFF switch of the lighting switch, display the switchboard. And a controller for turning on / off the screen display of the apparatus.

  A screen display control system for a switchboard display device according to claim 3, wherein the switchboard display device is linked to a switchboard display device, a human sensor installed at a desired location, and whether or not a person is detected by the human sensor. And a controller for turning on / off the screen display of the display device.

  The screen display control system for the switchboard display device according to claim 4 is linked to the switchboard display device, entrance / exit security equipment installed at a desired location, and entry / exit of a person by the entrance / exit security equipment. And a controller for turning on / off the screen display of the display device of the switchboard.

Since the screen display control system for the display device of the switchboard of the present invention is configured as described above, it has the following excellent effects.
(1) With the configuration described in the first aspect, the screen of the display device is always displayed or hidden by turning on / off the switch of the display device with a very simple configuration. It becomes possible to avoid the trouble of touching the screen at any time, and the workability is greatly improved.
(2) Further, since the screen display when it is unnecessary can be made non-displayed, it is effective in extending the life of the display device and saving power as in the conventional device.

(3) When configured as described in claims 2 to 4, the screen of the display device can be brought into the display state automatically only when necessary with a very simple configuration as in claim 1, so that workability is improved. In addition to improving, it is effective in extending the life of the display device and saving power.

An embodiment of a screen display control system for a display device of a switchboard according to the present invention will be described with reference to FIG.
FIG. 1 is an external perspective view for explaining the basic configuration and basic operation of a screen display control system for a display device of a switchboard according to the present invention.

  As shown in FIG. 1, the main configuration of the screen display control system 10 of the switchboard display device according to the present invention is the liquid crystal display 20 that is the display device of the switchboard 30 arranged inside the room 50 and the entrance portion of the room 50. The switch 22 of the liquid crystal display 20 of the switchboard 30 installed below the indoor lighting switch 52.

  In this way, when entering and leaving the room 50, the switch 22 of the liquid crystal display 20 is also turned on / off in the same way as the interior lighting switch 52 when entering or leaving the room 50, so that the operator always enters the room after entering the room. The screen of the liquid crystal display 20 is in a display state, so that the troublesome touching of the screen at any time can be avoided and the workability is improved.

  On the other hand, after the operator leaves the room, the screen of the liquid crystal display 20 is in a non-display state, and as in the conventional apparatus, power saving and life extension of the liquid crystal display 20 can be achieved.

The screen display control system of the switchboard display device of the present invention is not limited to the above-described embodiment, and various modifications are possible.
In addition to the above embodiment, ON / OFF of lighting switch ON / OFF, presence / absence of human detection by human sensor, and ON / OFF of screen display of switchboard display device in conjunction with human entrance / exit by entrance / exit security equipment If the controller is provided, the liquid crystal display can be brought into the display state only when it is automatically necessary, which is more effective.

It is an external appearance perspective view for demonstrating the basic composition and basic operation | movement of the screen display control system of the display panel display apparatus of this invention. It is a perspective view which shows schematic structure of the conventional switchboard. It is an external appearance perspective view of the outlet socket which performs the conventional automatic power distribution.
