[Industrial applications]

The present invention relates to a display data reference method for 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 lined up in urban areas,
The rooftops of these buildings are increasingly used as places for laying advertising devices such as signboards and neon towers. Also, with the development of information equipment, etc., a large display panel was built in such a place, and image patterns and the like were displayed thereon, and this was changed one after another so that various image information could be visually distributed. Display boards are now used. Such devices are provided in various places and are centrally managed from one management room via a telephone line or the like.

[Problems to be solved by the invention]

However, in such a conventional apparatus, what kind of image pattern data has already been sent from the control device on the control room side, that is, the control device on the sending side, for example, the personal computer 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. For that reason, due to forgetting, the image data already sent is sent repeatedly, or the display order of the image pattern is changed,
There has been a problem that the image pattern cannot be efficiently executed when it is desired to correct or improve the image pattern itself.

The present invention has been made in view of such a conventional problem, and a sender can easily recognize what kind of data such as an image pattern is stored in a control device on a display panel side. Another object of the present invention is to make it possible to confirm and confirm that double sending of data can be avoided, and that data can be changed and modified efficiently.

[Means for solving the problem]

The present invention, as shown in FIG.
The control device 13 has controllers 14 and 16 for exchanging data with another control device 15 via a telephone line or the like. A pattern number and a schedule number for identifying a schedule to be added to the order of each block or several blocks of data to be displayed on the display panel are determined, and these pattern numbers and schedule numbers are transmitted to the other via the controllers 14 and 16. It is configured to be able to recognize display data exchanged between the control devices 15.

[Action]

That is, according to the display data reference method of the display panel of the present invention, when issuing a reference command of the pattern number or schedule number to the control device 13 of the display panel 12 from the sending side,
In response to this, the control device 13 of the display panel 12 transfers the data of the pattern number or schedule number for identifying the data block or the schedule in the order of several blocks of the data. Then, this data is displayed in the form of a list on the control device on the sending side, for example, a CRT or a printer. Therefore, on the sending side, the data block sent to the display panel or its schedule can be confirmed.

〔Example〕

 The embodiments will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.
In the figure, a portion surrounded by a two-dot chain line shows a configuration of a receiving system, and the receiving system 11 includes a display panel 12,
A control device 13 for controlling the display panel 12 is provided, and a controller 14 for interfacing the control device 13 with a communication path such as a telephone line, for example, a modem. The display panel 12
A remote location is a personal computer system with other controls 15, such as a CRT, printer, and other peripherals, which is connected to a controller 16 similar to the controller 14, such as a modem, to a sending system. Is configured. The controller 16 of the sending system and the controller 14 of the receiving system are connected by a communication path 17 such as a telephone line.

The display panel 12 is configured such that a light-emitting element such as an incandescent lamp or a light-emitting diode formed in a matrix or a portion serving as a pixel can be changed into various colors. An image or the like is revealed by being changed according to the image pattern data sent from the system.

The control device 13 includes a CPU, a ROM, a RAM, a controller for controlling an image on the display panel 12, a driver for driving a light emitting element of the display panel, a serial port, a floppy disk controller, and other electronic circuits and a floppy disk driver. The serial port such as an RS-232C port is connected to the controller 14, and the driver and the like are connected to the display panel 12. In the ROM, data is exchanged with the sending side system, the display panel is controlled, or image data or the like sent from the sending side system is stored on a floppy disk, or the floppy disk A control program for reading out image data and the like stored in the CPU and executing various other operations is written. Further, the controller 14 converts a digital signal composed of a pulse train of a rectangular wave into an analog signal that fits within the band of the communication path, or conversely, receives such an analog signal and converts it into the pulse train of the rectangular wave. A commercially available one having a function of converting into a digital signal can be applied as it is.

The hardware configuration in the display data reference method of the display panel of the present invention is configured as described above. A large-capacity RAM may be used instead of the floppy disk driver. In such a case, the floppy disk driver and the floppy disk controller are omitted.

In the control program of the receiving system, routines for executing various commands and functions are described in a hierarchical structure in the ROM. The main ones will be described below.

FIG. 3 (a) schematically shows information exchange between the sending system and the receiving system. Prior to the main routine, there is a routine for detecting whether or not the sending system can use the receiving system. The routine includes, for example, the sending side system as shown in FIG. The system checks the password (3200) following the specific symbol string (ABC) that is the opening message sent by the 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 a response message to the sending system as shown in FIG. Then, the process proceeds to a main routine for receiving the next transmitted command.

The main routine forms a loop for receiving various commands, and waits for what commands are 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 pattern data is received on the receiving storage medium (eg, a floppy disk or RAM).
Execute the subroutine for saving in. At this time, a pattern number for identifying the image pattern data is sent before or after a data block that is the content of the image pattern data, and the pattern number is stored in a fixed area of the storage medium. Necessary information such as creation date and time and the area accommodated in the storage medium (head address or head sector, end address or tail sector, if the accommodation area is not continuous, the head address of the continuation head area) Or the first sector)
Are added and saved. When the execution of the subroutine is completed, the process returns to the main routine again and waits for a command newly sent from the sending system. Next, when a command requesting transmission of image pattern data already contained in the receiving system is sent from the transmitting system with the pattern number attached thereto, the receiving system sends the pattern number or the like. A subroutine for transmitting the image pattern data to the transmission side system is executed by referring to the area where the corresponding 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 command newly sent from the sending system. The execution of the main mutin, if a command to end the use of the receiving system has been sent from the sending system or if the state where nothing has been sent from the sending system has continued for 30 seconds, for example, The execution of the main routine is terminated, and the receiving system returns to the execution of the standby routine such as the password.

The receiving side system has a subroutine for sending the pattern number and its additional data individually or entirely to the sending side system in response to a request from the sending side system, as shown in FIG. 3 (a). When a command to execute this is sent from the sending system, the receiving system sends the corresponding pattern number from the area containing them as shown in FIG. And the additional data or all data stored in the area are transmitted to the transmission side system.

The receiving side system creates a schedule (schedule) for determining which of the plurality of image pattern data already transmitted and stored in the storage medium and in which order, It is stored in a fixed area of the storage medium, and the receiving system refers to the schedule and the time, and sequentially displays each image pattern on the display panel according to the schedule. ing. For example, if one screen is to be changed every three minutes from 8:00 am to one hour, 20 blocks of image pattern data are required. Displaying the same content in the same order every day is not interesting, and in the case of an advertising display panel, the advertiser's wishes, such as time of day, number of displays, etc., also need to be met. . Therefore, it is necessary to operate according to the above-mentioned schedule, and such a schedule is different from day to day, for example, by appropriately combining 20 blocks from several hundred blocks of image pattern data, for example, on a fixed date of every month. create. The schedule created in this way is given a schedule number and additional information (creation date, creation time) attached to the schedule, and is different from the storage area of the pattern number of the display pattern data in the storage medium. Housed in the area. In the previous example, the schedule was described in units of one hour. However, the schedule is created in units of two hours, in units of four hours, or in units of appropriate time. The schedule number for identifying the schedule and the additional data are individually or entirely shown in e (schedule number notification) in FIG. 3 (a) in the same manner as in the case of referring to the pattern number of the image pattern data. In response to a request from the sending system (e (see schedule) in FIG. 3A), the sending system is sent out.

In addition to the program for executing the functions as described above, the receiving system includes a pattern number of the image pattern, a schedule number of the schedule, and a command for changing and deleting the content and a command for changing the content. A subroutine and the like for executing the function are provided.

On the other hand, the password, the command, etc. are transmitted to the storage medium of the transmission side system, the identification symbol (pattern number and schedule number) and other data transmitted from the reception side system are stored in a memory, or A program (communication software) corresponding to the function of the receiving side system for displaying an identification symbol (pattern number and schedule number) on a CRT in a one-column format (FIG. 2) or printing out from a printer (FIG. 3) is provided. Yes, for example, in basic, machine language, or a mixture of these.

As described above, according to the display data reference method of the display panel of the present invention, identification symbols (pattern number and schedule number) are defined in the image pattern data and the schedule, and these identification symbols (pattern number and schedule number) are exchanged. In the sending system, it is possible to easily confirm whether or not the target image pattern data already exists in the receiving system, and to specify such (pattern number or schedule number) and to specify the contents. Image pattern data and the like may be transferred from the receiving system to the sending system.

However, for example, if the image pattern data produced by the sender system, which is the manager, is already stored in the receiver system, the manager later notices that the image has a poor part, and There is a case where a sender system, which is a specialist such as a design, is requested to correct the image. The sending side system that has received the request may receive the transfer of the image pattern data with the pattern number, change or correct the image pattern data as appropriate, and send it to the receiving side system.

FIG. 3 (b) schematically shows a display schedule using the operation time of one day as a unit. A schedule from one line to a schedule N line is scheduled for each day, and the image pattern is identified in each line. Is recorded.
The schedule file for each day determined in this way is assigned a pattern number which is an identification symbol for identifying the schedule file, and is stored in the storage medium. The lower part of the figure is expressed in a card format, but for ease of understanding, it is expressed in this manner. However, in actuality, it is stored in a fixed area of the storage medium for each file.

〔The invention's effect〕

As described in detail above, according to the present invention, a pattern number is determined for each data block such as image pattern data displayed on a display panel, or several blocks such as a plurality of image pattern data displayed on the display panel. A schedule number is determined for each schedule that participates in the data order, and these identification symbols (pattern number and schedule number)
The transmission / reception can be performed via a communication path, so that the sending system can easily and quickly confirm the presence / absence of image pattern data or the like in the receiving system. In addition, it is possible to efficiently change display pattern data, update the schedule table, and the like.
