Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for remotely controlling the screen of a video projector used for displaying the status of a plant in the field of process automation.

[0002]

2. Description of the Related Art Conventionally, in fields such as office automation and process automation, an icon such as a pull-down menu is displayed on the screen to improve the operability of an operator, and the icon is selected using a coordinate input device such as a mouse. However, it has been performed such that an operator develops a desired screen.

By doing so, even an operator unfamiliar with the key operation or an operator who is not familiar with the operation method can perform the operation easily and accurately. In other words, according to this method, the next operation can be associated even without a manual compared to the method of tapping multiple keys from the keyboard to expand to the next screen, which greatly improves operability. Is.

[0004]

In recent years, especially in the field of process automation, there are increasing cases where a video projector is required as a replacement for a graphic panel.

A plant operator (operator) has gathered all of the graphic panels on the console that have a panoramic view of the situation of the entire plant that existed in the past into a CRT display. It is said that he is uneasy because he does not know the driving condition. Currently, the only way for the administrator to know the operating status of the plant is to operate the console and check the displayed screen, as with the operator.

Since the plant manager wants to monitor and operate the screen for the above-mentioned purpose, it does not require complicated operation, and in many cases it is sufficient to call a specific screen with one touch. However, I want to operate a large video projector that can replace the graphic panel that can be seen from any position in the room, and display the desired screen from any position in the room.

However, the coordinate input device represented by a mouse, a trackball, or a touch screen has a problem that it can be used only near the display device. In other words, it is impossible to operate the screen of the video projector at a remote place.

Now, considering the graphic screen of the conventional supervisory control console, the plant flow screen displayed on the graphic panel is the CR of the console.
In many cases, one T display cannot display all the images, so
The screen image for four times the RT screen was stored in the frame memory built into the console and moved to the required place when needed (this operation is called scrolling) to obtain the necessary information. However, when you want to display one large screen by arranging multiple video projectors, you can display necessary information such as plant operating status from anywhere in the room on the video projector without any operation. There is also.

In this case, the operator operates a plurality of video projectors, but normally one input device is installed on one screen on the monitor and control console, so that it corresponds to the screen to be operated. The operation to select the channel of the remote control device (remote control) entered, and the operation became complicated. However, the complicated operation is against the original purpose.

Therefore, according to the present invention, in a display device in which a plurality of screens are arranged so as to be able to display a continuous screen, it is necessary to perform a screen selection operation with a remote controller when the continuous screen is displayed. The purpose is to realize a remote coordinate input device.

[0011]

A remote coordinate input device according to the present invention comprises a plurality of large screens arranged side by side in the lateral direction, a video project controller provided for each large screen, and each large screen. One-to-one correspondence with each large screen and a coordinate detection device that is placed on the top of the screen and outputs a command signal that receives the command signal from the remote controller and adds the coordinates of the screen when it corresponds to the identification code And a coordinate input control section which receives a command signal from the coordinate detection device and controls passage of an input signal in accordance with the content of the command signal and a coordinate input control section which is provided in one-to-one correspondence with the coordinate input control section. A video project that generates and outputs a video signal of a screen to be displayed based on an input signal and that corresponds to a large screen specified by the input signal. A control console having a built-in control unit which is connected to a central processing unit, a main memory, a LAN control unit, etc., by an internal system bus, which sends an image display control unit for sending a screen based on this video signal to a large screen to a controller , A remote controller for emitting a command signal to which a corresponding identification code is added to each of the plurality of large screens by operating a plurality of keys to select and operate each coordinate detecting device.

[0012]

In the remote coordinate input device of the present invention, when a request to display a desired screen is made by operating the key of the remote controller, a command signal including an identification code for specifying the display screen is emitted from the remote controller, The coordinate detection device of the screen responds, the command signal added with the coordinates of the screen is received by the coordinate input control unit corresponding to the screen, and the image display control unit generates a video signal of the corresponding screen, This video signal is sent to the video project controller corresponding to the specified large screen,
The desired screen is projected onto the large screen.

Further, when a display request for displaying a large screen connected to a plurality of large screens is made by the remote controller, it is included in the command signal detected by the coordinate detecting device and sent to the coordinate input control section. Since the screen selection identification code signal portion is invalidated by the coordinate input control unit and the entire screen is automatically handled as one unit, each image display control unit displays the large screens in series. By splitting a large screen and generating and outputting a video signal to display on each screen, and projecting it on the large screen via each video project controller, a large connection across multiple large screens can be achieved. The screen is displayed.
