Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen input device for a display device such as a multi-stage product CRT display device in which a plurality of display devices are vertically arranged.

[0002]

2. Description of the Related Art A multi-stage CRT display device is used as a space-saving man-machine interface by arranging three CRT display devices vertically as shown in FIG. In such a case, the power system display, the management drawing, the data and the like are displayed in a distributed manner on each CRT display device, thereby eliminating the need for screen switching on one CRT display device.

In such a multi-stage CRT display device, a touch sensor or a light pen is provided as an input means from the screen displayed on each CRT display device, and operation of the device (operation, stop, etc.) can be performed from the CRT display screen. It is possible. In this operation, for example, when a device symbol on the screen is selected, the operation window of the device is displayed on the CRT screen, and when the operation symbol in the operation window is touched, a driving command is output and the field device is operated.

In such an operation, since it is difficult to directly operate the screen of the upper CRT display device in the multi-stage CRT display device, the display screens of the upper CRT display device and the lower CRT display device are exchanged (swap). ), CR at the bottom
An input operation from the T display device is performed.

[0005]

In the conventional multi-stage CRT display device, the operation input to the screen requires a screen switching operation and control between the upper CRT display device and the lower CRT display device, which results in a work burden on the operator. To raise.

Further, if the lower CRT display device fails, the operation input of the upper CRT display device becomes impossible.

It is an object of the present invention to provide a screen input device that can perform an input operation without requiring a screen swap operation, and can perform an input operation even when a lower display device fails.

[0008]

In order to solve the above problems, the present invention provides a multistage stack display device in which a plurality of display devices are vertically arranged, and a selection switch for selecting a screen input to each of the display devices. And a remote control switch having a cursor movement key for moving a cursor on the screen of the selected display device and an enter key for validating the position designation by the cursor.

Further, the present invention is characterized in that the remote control switch includes a liquid crystal panel with a touch processor for displaying an operation window of a selected display device and performing a touch operation of an operation key of the operation window.

[0010]

The screen input to the display device is directly input to the display device by using the remote control switch, and it is not necessary to replace the screen of the upper display device with the lower display device.

Further, by providing the remote control switch with a liquid crystal panel with a touch sensor for displaying the operation window of the display device and inputting the operation keys, the cursor movement operation is not required for the operation window input.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a configuration of operation keys of a remote control switch showing an embodiment of the present invention. The remote control switch is arranged at a position where an operator can easily operate it together with a keyboard, a mouse, etc., and is connected to a computer for controlling a multi-stage CRT display device to generate a control signal by an operation key.

The operation keys of the remote control switch are for selecting the signal frequency selection switches _{11 to} 1n corresponding to each CRT display device and for moving the cursor on the screen of the selected CRT display device in the vertical and horizontal directions. comprises a cursor moving keys ₂₁ to _24, and enter key 3 to enable the position specified by the cursor.

According to the present embodiment, the operation input to the screen of the multi-stage CRT display device can be made from the remote control switch.

For example, for the operation input to the upper CRT display device, one of the CRT selection switches 1 _{1 to 1} n of the remote control switch is selected by operating the corresponding switch, and then the cursor movement keys 2 _{1 to} 2 n.
Use to move the cursor to the device symbol displayed on the screen of the CRT display device, and finally press the enter key 3. As a result, the device operation window is displayed on the screen of the CRT display device, and the cursor movement keys 2 ₁ to 2 ₄
Use to select the "Driving" symbol in the operation window and press the Enter key 3. As a result, the computer outputs an operation command for operating the device.

Therefore, the operation input to the upper CRT display device can be directly input from the remote control switch without replacing the screen with the lower CRT display device. Further, even when the lower CRT display device fails, the monitoring operation can be performed only by the upper CRT display device.

Incidentally, the operation input to the lower CRT display device may be an input from a touch sensor as in the conventional case, or an input from a remote control switch may be used together.

FIG. 2 is a block diagram showing the operation keys of a remote control switch according to another embodiment of the present invention. 1 is different from FIG. 1 in that a liquid crystal panel 4 with a touch sensor is provided.

The liquid crystal panel 4 has a display function of displaying the same operation window display as that of the selected CRT display device, and the operation of the symbol displayed in the operation window is performed by using the touch panel attached to the liquid crystal panel 4. For example, it enables operations such as "running" and "stopping" the equipment.

The window displayed on the liquid crystal panel 4 is dynamically changed according to the type of equipment selected on the screen of the CRT display device.

Therefore, according to the present embodiment, the cursor movements for the "run" and "stop" operations of the device are performed in the same manner as operating the window on the screen of the CRT display device selected by the remote control switch. It can be performed directly without performing, and the operability is further improved.

In the embodiment, the case of the CRT display device is shown, but the present invention is applied to a display device in which other display devices such as a liquid crystal display device are stacked in multiple stages, and the same operational effect is obtained.

[0023]

As described above, according to the present invention, since the screen input to the display device is performed by the remote control switch, the screen input operation to the upper display device and the screen swap operation to the lower display device can be performed. It is not necessary, and there is an effect that the screen input operation can be performed even when the display device in the lower part fails.

Further, since the remote control switch is provided with a liquid crystal panel with a touch sensor for performing the same display and operation key input as the operation window of the display device, a simple operation can be performed instead of the cursor movement and the enter key operation with respect to the operation window of the display device. Become.
