Description

[Detailed Description of the Invention] [(Already required)] Regarding the display data reference method of the display panel for smoothly operating the display panel installed remotely via a telephone line etc., how is the control device on the display panel side equipped? The sending side can easily recognize or confirm whether data such as image backups with the same content are saved, avoid double sending of data, and efficiently change or correct data. The purpose of this is to connect a sending-side control device and a receiving-side control device having a display panel through a communication path, and to write an identification symbol of each block of data to be displayed on the display panel, or to write an identification symbol and each block of data to be displayed on the display panel. means for transmitting and receiving an identification symbol for identifying a schedule that affects the display order of blocks between the sending-side control device and the receiving-side control device via the communication path; and a means for determining the schedule using the identification symbol on the sending side.

[Industrial application field]

The present invention relates to a system for referring to display data on a display panel for smoothly operating a display panel installed remotely via a telephone line or the like.

[Conventional technology]

In recent years, large buildings have been erected in urban areas, and the rooftops of these buildings are increasingly being used as places for advertising equipment such as billboards and neon towers. In addition, with the development of information devices, large display panels were built in such places to display image patterns, etc., which were changed one after another, making it possible to visually disseminate various image information. Display boards began to be used.

Such devices are installed in various locations and are centrally managed from one management room via telephone lines or the like.

[Problem to be solved by the invention]

However, in such conventional systems, the control unit on the control room side, that is, the sending side, for example, the personal computer, does not know what kind of image pattern data is already sent to the control device on the display panel side, or in what order. The sending side could not easily recognize whether the image pattern was set to be displayed on the display panel. Therefore, due to forgetfulness, there are problems in which the image data that has already been sent is sent overlappingly, or when the display order of the image pattern is changed, or when the image pattern itself is to be modified or improved, it cannot be executed efficiently. Ta.

The present invention has been made in view of such conventional problems, and is based on the control of the display panel. IIl' The sending side should be able to easily recognize or confirm what kind of data such as image patterns is stored in the device, avoid double sending of data, and prevent data changes (t7 correct). The purpose is to make it possible to carry out such tasks efficiently.

[Means to solve the problem]

As shown in FIG. 1, the present invention includes a display panel 12 and a display panel 1
2, and the control device 13
is equipped with a controller 14.16 that exchanges data with another control bag 215 via a telephone line or the like, and controls each block of data to be displayed on the display panel 12 or several blocks of data to be displayed on the display panel. An identification symbol for identifying a schedule related to the order is determined, and the identification symbol is transmitted and received between the control devices 15 via the controllers 14 and 16 so that display data can be recognized.

[For production]

That is, according to the display data reference method of the display panel of the present invention,
When the sending side issues a command to refer to the identification symbol to the control device 15 of the display panel 12, the control device 15 of the display panel 12 receives this and takes part in the order of the data block or several blocks of the data. The identification symbol data that identifies the schedule is transferred. This data is then displayed in the form of a list on the sending side control device, such as a CRT or printer. Therefore, the data block being sent to the display panel or its schedule can be checked on the sending side.

〔Example〕

The present invention will be described below along with examples with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, the part surrounded by the two-dot chain line shows the configuration of the receiving system, and this receiving system 11 includes a display panel 12, a control device 13 that drives and controls the display panel 12, and a control device 13 that controls the display panel 12. It has a controller 14, such as a modem, that interfaces with a communication path such as a telephone line. Is there another system located away from the display panel 12? II device 15
For example, there is a personal computer system equipped with a CRT, a printer, and other peripheral devices, and this control device 15
A controller 16 similar to the controller 14 is connected to, for example, a modem to constitute a sending system. The controller I6 of the sending system and the controller 14 of the bone side system are connected by a communication path 17 such as a telephone line.

The display panel 12 is configured such that light emitting elements such as incandescent lamps or light emitting diodes formed in a matrix or portions that become pixels can be changed to various colors, and the control device 13 controls the density, illuminance, etc. The image is changed according to the image pattern data sent from the system to reveal the image.

The control device 13 includes a CPU, ROM, and RAM.

It includes a controller that controls the image on the display board 12, a driver that drives the light emitting elements of the display board, a serial board, a Fronby disk controller, other electronic circuits, a Fronby disk driver, etc., and the serial board, for example, R3- The 232C boat is connected to the controller 14, and the driver etc. are connected to the display panel 12. The ROM is used to exchange data with the sending system, to control the display panel, to save image data etc. sent from the sending system to a floppy disk, or to store the image data etc. sent from the sending system on a floppy disk. A control program is written for reading image data etc. stored in the computer and for executing various other operations. The controller 14 also converts a digital signal consisting of a rectangular wave pulse train into an analog signal that falls within the band of the communication channel, or conversely receives such an analog signal and converts it into the rectangular wave pulse train. Any commercially available device that has the function of converting into a digital signal can be used as is.

The heart configuration in the display data reference system of the display panel of the present invention is configured as described above. Note that a large-capacity 11 AM may be used instead of the floppy disk driver, and in that case, the floppy disk driver and floppy disk controller are omitted.

In the control program for the bone system, routines for executing various commands and functions are written in the ROM in a hierarchical structure, and the main ones will be explained below.

FIG. 3 (al) schematically shows information exchange between the sending system and the receiving system. Prior to the main routine, it is determined whether or not the sending system is allowed to use the bone system. There is a detection routine, and its contents are, for example, as shown in Figure 3 (al), which checks the bus '7-1' (3200) following the specific symbol string (ABC) that is the opening message sent by the sending system. If such a specific symbol string and password match a predetermined specific symbol and a password in a predetermined list, the receiving system sends the message to the sending system as shown in Figure 3 fb). A response message is sent to the effect that usage is permitted.Then, the process proceeds to the main routine for accepting the next command sent.

The main routine consists of a loop for receiving various commands, and waits for what kind of command will be sent from the sending system via the communication path 17 and the controller 14. For example, when the sending system sends a command to send image pattern data, the image data is stored on the receiving side's storage medium (for example, a floppy disk or RA).
M) Execute the subroutine for saving.

At that time, an identification symbol for identifying the image pattern data is sent before or after the data block that is the content of the image pattern data, and the identification symbol is placed in a predetermined area of the storage medium. For example, the date and time of creation, the area accommodated in the storage medium (first address or first sector, last address or last sector, or first address of the continuous optical area if the accommodation areas are not consecutive) or the first sector, etc.)
etc. are added and saved. When the execution of the subroutine is completed, the process returns to the main routine again and waits for a new command to be sent from the sending system. Next, when the sender system sends a command requesting to send the image pattern data already stored in the receiver system with the identification symbol attached, the receiver system sends the image pattern data that is already stored in the receiver system. A subroutine for transmitting the image pattern data to the sending system is executed by referring to the area where the image pattern data is located from the area containing the image pattern data. When the execution of this subroutine is completed, the process returns to the main routine again and waits for a new command to be sent from the sending system. The execution of the main routine is executed when a command to terminate the use of the receiving system is sent from the sending system, or when nothing is sent from the sending system for 30 seconds, for example. If so, the execution of the main routine is terminated and the recipient system returns to execution of the password, etc. standby routine.

The receiving system has a subroutine for sending the identification symbol and its additional data for each IM or all of it to the sending system in response to a request from the sending system, as shown in FIG. 3(C). When a command to execute this command is sent from the sending system, the receiving system stores the corresponding identification symbol and its addition from the area as shown in FIG. 3(d). Send the data or all data stored in that area to the sending system.

creating a schedule for determining which of the plurality of image pattern data that has already been sent to the receiving system and stored in the storage medium is to be displayed and in what order; The images are stored in a predetermined area of the storage medium, and the receiving system refers to this schedule and time and sequentially displays each image Bakun on the display panel according to the schedule. ing. For example, in one hour from 8 o'clock in the raw part, 3 on each side.
If the screen is to be changed every minute, 20 blocks of image pattern data are required. Displaying the same content in the same order every day would be uninteresting, and in the case of advertising display boards, the advertisers' wishes, such as time of day and number of times they should be displayed, vary, and it is necessary to meet all of these requirements. . Therefore, it is necessary to operate according to the schedule as described above, and such a schedule differs from day to day. A schedule is created, for example, by suitably combining 20 blocks of image pattern data from several hundred blocks of image pattern data, for example, on a fixed date every month. The schedule created in this way is attached with an identification symbol and additional information thereon, and is stored in a predetermined area of the storage medium that is different from the storage area of the identification symbol of the display pattern data. In the previous example, the schedule table was explained in units of 1 hour, but this schedule may be created in units of 2 hours, 4 hours, or any other suitable time unit. The identification symbol for identifying this schedule and its additional data are shown in FIG. 3(e).

As shown in parentheses (), the data is sent to the sending system individually or in its entirety in response to a request from the sending system, as in the case of referring to the identification symbol of the image pattern data.

In addition to the program that executes the above-mentioned functions, the receiving system includes a command for changing or deleting the image pattern identification symbol, the schedule identification symbol, and its contents, and a command for changing or deleting the identification symbol for the image pattern, the identification symbol for the schedule table, and the contents thereof. Subroutines and the like are provided to execute the functions.

On the other hand, the storage medium of the sending system contains the password,
Sending commands, etc., storing the identification symbol and other data sent from the receiving system in memory, or converting the identification symbol to C in the 11>1 format (Figure 2).
There is a program (iJ71 communication software) corresponding to the functions of the receiving system for displaying on the RT or printing out from the printer (Fig. 3), and is written in, for example, basic or machine language, or using a mixture of these. .

As described above, in the display data reference method of the display panel of the present invention, an identification symbol is defined in the image pattern data or the schedule, and by sending and receiving the identification symbol, the sending system transmits the target image pattern to the receiving system. It is possible to easily check whether or not the data already exists, and to specify such an identification symbol so that the contents such as image pattern data etc. can be transferred from the receiving system to the sending system. You can also do that.

However, for example, if the image pattern data produced by the sending system A, which is the administrator, is already stored in the receiving system, the administrator later notices that there are some poor parts in the image. The sending system B, which is a specialist such as a graphic designer, may be requested to modify the image. The sending system B, which has received the request, may receive the image pattern data with the identification symbol, change or modify it as appropriate, and then send it to the receiving system.

FIG. 3 (bl) schematically shows a display schedule in units of daily operation time. Schedule 1 to schedule N rows are scheduled for each day, and each row identifies the image pattern. An identification symbol is recorded.The daily schedule file determined in this way is given a pattern number, which is an identification symbol for identifying this schedule file, and is stored in the 4g medium.

In the lower part of the figure, the information is expressed in a card format for ease of understanding, but in reality, each file is stored in a certain area of the storage medium.

〔Effect of the invention〕

As described in detail above, according to the present invention, each data block, such as image pattern data, to be displayed on the display panel or the order of several blocks of data, such as a plurality of image pattern data, to be displayed on the display panel. Since an identification symbol is determined for each given schedule and the system is structured so that the identification symbol can be sent and received via a communication path, the sending system can easily check the presence or absence of image pattern data, etc. in the receiving system. Therefore, it is possible to avoid double sending or forgetting to send data, and it is also possible to change display button data, update the schedule, etc. efficiently.
