(Industrial Application Field) The present invention relates to a display device control method for controlling a display device that displays various display patterns on a large display panel installed outdoors.

[Conventional technology]

BACKGROUND ART In recent years, large display panels whose display patterns can be changed sequentially have been installed on the rooftops of buildings in downtown areas and office districts, and are used for advertising, publicity, guidance, etc. The information data to be displayed on a display device having such a display panel is created, for example, on a personal computer (hereinafter referred to as a personal computer) installed in a control room located a little away, and the created information data is first transferred to a floppy disk drive. It is sent to a storage device such as , and saved on a storage medium (floppy disk). The personal computer and the display device are connected via a modem provided on both the display device side and the personal computer side, and a communication line connecting these modems, such as a telephone line. First, the information data stored on the floppy disk is read by the personal computer and sent via the modem and the communication line.

The display device includes a CPU, ROM, RA in addition to the modem.

Contains control data for regulating the display order etc. The information data received via the modem is written into a predetermined memory area, classified by data type. Then, the CPU of the display device refers to the sent control data regulating the display order of the display patterns and displays a series of display patterns one after another on the display panel.

[Problem to be solved by the invention]

By the way, in the display control method of the conventional display device, a series of display patterns are simply endlessly displayed on the display panel in accordance with the control data.

Therefore, for example, if sudden news such as ``Panyu York stock price crash'' or ``Mt. , if necessary,
This involves work such as adding display data that represents the display pattern. Then, after the above-mentioned sudden display for a while, it may be necessary to return to the original state depending on the case. There is a problem that such work is time consuming, extremely troublesome, and inconvenient. Furthermore, while such work is being carried out, the display on the display panel must be stopped, which reduces the efficiency of use of the display device and results in economic loss.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display device control method that allows a desired display pattern to be displayed easily and immediately by interrupting 5 normal displays without interrupting the display on the display panel. shall be.

[Means to solve the problem? FIG. 1 is a principle block diagram explaining the present invention.

The display device 1 has a large display panel 2 in which a large number of display elements serving as pixels are arranged in a matrix and can display characters, pictures, figures, and other display patterns. The display mode, display order, etc. are controlled by the control device 3. The control device 3 is connected via a modem to a personal computer 5 equipped with a modem via a communication line 4.

On the other hand, the control device 3 is a computer system equipped with a CPU, ROM, RAM, input/output board, and other necessary electronic circuits, and these configurations and software combine to cause the control device 3 to display a series of display patterns. A display pattern display order regulation means for regulating the order etc. to be displayed on the display panel 2 as time passes; An interrupt display means is provided for determining whether or not an interrupt display in which a display pattern is displayed in an interrupt manner is possible, and for executing the interrupt display when the interrupt display is possible.

[Function] The information data introduced as serial data from the personal computer 5 is written into the RAM in the control device 3 after being classified by data type. Normally, a series of display patterns are sequentially displayed on the display panel 2 over time according to the procedure of the display pattern display order regulating means. During this time, the interrupt display means monitors whether there is a request from the personal computer to interrupt the currently ongoing display and display a new display pattern such as breaking news. When this request is received, the interrupt display means transmits the information data sent from the personal computer to the R.
AM, determines the appropriate time to display the new display pattern on the display panel, and starts displaying the new display pattern at that time. The display starts in this manner, and when the display of the new display pattern is finished, the display returns to the normal display pattern that had been interrupted and continues.

[Embodiment 3] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a schematic block diagram showing a communication model for operating a display device under the control of the display device control method of the present invention. In the figure, the display device has a large display panel 10 in which a large number of display elements serving as pixels are arranged in a matrix and can display characters, pictures, figures, and other display patterns.
The display panel 10 is installed outdoors and is electrically connected to the control device 11.
This is connected. Then, the control device 11 controls the display mode, display order, etc. f! It's intimidating.

The control device 11 is connected to a personal computer 13 equipped with a modem via a communication line 12 via a modem.

On the other hand, the control device 11 is a computer system equipped with a CPU, ROM, RAM, input/output board, and other necessary electronic circuits, and these components and software combine to provide the control device 11 with a series of A display pattern display order regulating means for regulating the order in which the display patterns should be displayed on the display panel 10 over time, and temporarily suspending the display that is being displayed while being regulated by the display pattern display order regulating means. An interrupt display means is provided for interrupting and displaying another display pattern.

During normal operation of the display device, the personal computer 13 transmits general control data for regulating the order of display on the display panel 10 and display data representing a display pattern to the control device 11. . The control device 11 stores the sent data in a predetermined area of the RAM, classifying it by data type. Naturally, these exchanges are performed by the communication programmer 1 written in the ROM according to a known communication protocol.

To start displaying on the display panel IO, an operation start command is issued from the personal computer 13 side, and this is sent to the control device 1.
1 is received, the program described below branches to start displaying on the display panel 10.

Note that if the general control data and display data have already been sent to the control device 11 in the previous communication and no changes are required, only the operation start command is issued to start the operation of the display device.

FIG. 3(a) is an explanatory diagram showing the format of the general control data stored in the RAM, and FIG. 3(b) is an explanatory diagram showing the format of the display data. The general control data shown in FIG. 3(a) includes identification data of the display pattern in the left column, the duration to be displayed on the display panel 10 in the right column, and identification data indicating whether or not to interrupt. They are placed respectively. There is no problem with these orders as long as they are consistent. Then, such at least three data groups are displayed on the display panel 1.
They are provided in order from the top to the bottom in the order in which they are displayed.

In the display data shown in FIG. 3(b), data corresponding to the display patterns to be displayed on the display panel 1o is provided in order for each display pattern. Although not shown, this data RAM
The above location can be read out individually by referring to a correspondence table (directory) of the storage start address of the display pattern data corresponding to the display pattern identification data.

FIG. 4 is an explanatory diagram showing the format of control data for interrupt operation sent from the personal computer 13 when urgent information is displayed by interrupting normal display operation. The format of this control data is almost the same as the above-mentioned membrane control data, however, since it is unnecessary, no identification data indicating whether or not an interrupt is allowed is provided. however,
If the configuration is such that the interruption of other information is allowed during the interruption display, the format of this control data can also be the same as that of the above-mentioned film control data.

The personal computer 13 stores control data for interrupt operations, as well as
When there is new display pattern data that has not yet been sent to the control device 11, the display pattern data is sent to the control device 11 in the same format as the display data shown in FIG. 3 0)).

FIG. 5 is a flowchart showing the flow of a control program that controls both normal display and interrupt display.

As mentioned above, when the operation start command is issued from the PC 13 side and the control device 11 receives it,
CP (J) of the control device 11 starts executing a program of the flow shown in FIG. 5. The entry indicates the entrance of the program.

In step S1, data in a corresponding line (initially, the first line) is read out of the -membrane control data shown in FIG. 3(a). Next, in step S2, the identification data indicating whether or not the interrupt can be accepted is checked to determine whether or not the interrupt can be accepted. If the interrupt cannot be accepted (NO), the process proceeds to step S3, where the display pattern corresponding to the identification data of the display pattern is read out and developed in a predetermined area (video RAM area) of the RAM.

Subsequently, in step S4, a signal corresponding to the display pattern is output to the output boat to which the display panel 1o is connected, and the display pattern is displayed on the display panel 10.

Next, the process proceeds to step S5, and the process waits for the display duration time on the display panel 10 specified by the -film control data to elapse.

Next, in step S6, the value of the pointer that manages the order of display on the display panel in normal display is increased by +1.
(increment).

Although the description is omitted in the general control data shown in FIG. 3(a), the bottom line of the -r control data contains a jump number for returning to the first line or an appropriate line. be. Then, in step S7, it is determined whether the jump destination number exists or not. As a result, if the jump destination number has not been designated (NO), the process returns to step SI, and thereafter, access is made line by line according to the membrane control data to advance the display on the display panel.

On the other hand, if the result of the judgment in step S is that the jump number is specified (YES), the process advances to step S8, sets the value of the jump number in the pointer, returns to step S1, and continues , the display on the display panel is progressed by accessing each line in order from the jump number. In this way, the display on the display panel in the normal display continues. In addition, specifying whether or not to allow interrupts is as follows.
The consecutive pieces of information from being uninterruptible to being interruptible are closely related (for example, information for the same sponsor), and will not make sense unless they are displayed on the display board as a sequence of events. This is to prevent you from becoming confused or feeling uncomfortable.

In step S2, if interrupts are possible, the process branches to step S. At this point, it is determined whether or not a command requesting interrupt display has been sent from the personal computer 13. If there is no request for interrupt display (NO), the process returns to step S3 and continues the routine for normal display.

If a command requesting interrupt display has been sent from the personal computer 13 (YES), the process proceeds to step 310, and the corresponding line of data is selected from among the control data for interrupt operation shown in FIG. Read out. If it is the first line, read the first line. Next, the process proceeds to step Sl+, where a display pattern corresponding to the identification data of the display pattern is read out and developed in a predetermined area (video RAM area) of the RAM. Then, in step S12, a signal corresponding to the display pattern is output to the output boat to which the display panel 10 is connected, and the display pattern is displayed on the display panel 10.

In step S13, as in step S5, the CPU waits for the display duration time on the display panel 10 specified by the control data for the interrupt operation to elapse. When this duration period has elapsed, in step S, the value of the pointer that manages the display order on the display panel in the interrupt display is increased by +1.
(increment). Thereafter, the process proceeds to step srs, where it is determined whether a series of displays in the interrupt display has been completed. As a result, if the series of displays have not all been completed (No), the process returns to step S1, reads the contents of the subsequent line in the control data for the interrupt operation, and displays the display in the same manner as above. The display continues on to board 10.

In step SI5, if the series of displays in the interrupt display is completed (YES), the process returns to step S3 and the routine for normal display is restarted.

Although the number of the flowchart in FIG. 5 is not shown, in reality, when there is a request for interrupt display from the personal computer 13, while the normal display is performed, interrupt processing to the CPU or another sub-CPU etc. is performed. Control data for the interrupt operation and necessary display pattern data that are sent following the interrupt display request command are stored in the memory. Therefore, the determination in step S9 is made not by checking in real time whether there is an interrupt display request command sent from the personal computer 13, but by checking the state of a flag that identifies whether or not there is an interrupt display request command. ing.

Effects of the Invention] As described above in detail, according to the present invention, when it is desired to report emergency news, etc., a desired display pattern can be easily and immediately displayed normally without pausing the display on the display panel. So that it can be displayed by interrupting. Therefore, troublesome work can be reduced and the efficiency of use of the display device can be improved, making it possible to operate the display device economically.
