Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-sized liquid crystal display device used as a plant monitoring panel and a display method thereof.

[Conventional technology]

In the past, fixed display devices made of mosaics were used as industrial plant monitoring panels, but in recent years, large-sized liquid crystal display devices have been developed, and the transition from fixed to liquid crystal monitoring panels has been triggered. Is being promoted.

As described in Japanese Patent Application Laid-Open No. 61-256321, such a large-sized liquid crystal display device draws a graphic macro issued by a controller on a liquid crystal plate by a laser beam in vector drawing, and uses a Xe lamp or the like to perform large-scale drawing from the back. The image is projected on the screen to display characters, graphics, and the like on a large screen.

By the way, when changing the plant by increasing or remodeling the plant constituent equipment, in a large liquid crystal display device, it is necessary to change the physical mosaic, and the function stop time of the plant becomes longer, but in the liquid crystal display device, Since only the monitoring panel is changed by software, the time for stopping the function of the plant can be reduced, which is economically advantageous.

On the other hand, from the viewpoint of plant monitoring operation, the plant monitoring panel displays the configuration and status of the plant, and also displays information on unexpected situations of the plant and handover information to the operator. Displays character strings and shapes,
A function for informing a plurality of drivers is indispensable.

In the fixed display device, the above function was realized by attaching a tag with a symbol or a character string to the board with a magnet, but in the liquid crystal display device, an arbitrary character string or a graphic can be placed at an arbitrary position. There is no function of inputting a tag, and since the projector is of a rear projection type, it is not practical to attach the tag or the like to the screen surface.

Therefore, as shown in FIG. 9, a computer system provided with a small screen display device 2 separately from the large liquid crystal display device 1 has been considered.

In such a system, the computer 3 transmits the plant data via the dataway 4 to the liquid crystal controller 5.
After transmitting the received plant data to screen image data, the liquid crystal controller 5 transmits the received plant data to the liquid crystal projection type large screen 7 and the small screen controller. 6 is displayed on the small screen 8 respectively.

Further, the driver inputs a character string or the like to be displayed on the liquid crystal projection type large screen 7 from the data input device 9 which is a component of the driver on the small screen display device 2. In this case, the character string and the like are displayed on the small screen 8 so as to be superimposed on the characters and figures originally displayed on the small screen 8, and the driver checks whether the display position and the characters and figures are correct. At this time, the character strings and the like input on the small screen 8 are not displayed on the large liquid crystal projection type screen 7.

When the driver confirms that the display position, characters, figures, and the like are accurate, the driver issues an instruction to end the input from the data input device 9. Thereby, the small screen controller 6 transmits the input data to the computer 3. After receiving the input data transmitted from the small screen controller 6, the computer 3 transmits the data to the liquid crystal controller 5. After receiving the data, the liquid crystal controller 5 displays the data on the large liquid crystal projection type screen 7 synthesized with the created screen image data.

[Problems to be solved by the invention]

However, in the above-mentioned prior art, new hardware called a small screen display device must be introduced separately from a large liquid crystal display device, and there is a disadvantage that a computer system becomes expensive.

Further, since the large-sized liquid crystal display device and the small-sized screen display device are completely independent, there are the following problems.

The software configuration of the computer system is as shown in FIG. 10, but the fixed screen data 10 for editing the plant screen showing the plant configuration and the plant data from the computer 3 for editing the screen data are displayed. The variable data display definition data 11 and the screen editing processing 12 for creating screen display image data are separately incorporated in the liquid crystal controller 5 and the small screen controller 6 and are not integrated.

Since the plant data must be transmitted from the computer 3 to the liquid crystal controller 5 and the small screen controller 6 via the data way 4 in parallel, the computer 3
And the transmission load of the data way 4 are multiplied.

In particular, in the above description, since the screen data is not unified, when changing the screen being displayed on the large LCD projection screen 7 when the plant equipment is remodeled, the fixed screen data 10 and the variable data display definition data in the LCD controller 5 are changed. 1
1 and the same data 1 in the small screen controller 6
0 and 11 must be transmitted simultaneously. If the screen data in the liquid crystal controller 5 and the screen data in the small screen controller 6 are different, the small screen controller 6
The input data is from a large LCD screen 7
There is a risk that transmission and input will be made on plant equipment different from the equipment displayed on the small screen 8 above, and another operator will know an incorrect plant situation.

An object of the present invention is to provide a large-sized liquid crystal display device capable of reliably transmitting information such as messages and notes between drivers without installing large-scale hardware, and a display method thereof. .
