DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information display system that enlarges and displays character string information in predetermined dot matrix units.

[Technical background of the invention and its problems]

Conventionally, a control side (hereinafter referred to as the center side) and a controlled side (hereinafter referred to as the terminal side) are connected through a predetermined transmission path, and pattern data such as road information processed on the center side is transmitted to the terminal side. For example, in a so-called information board control system that displays on a large outdoor dot matrix display board, an operator must input pattern data dot by dot at the center to display on the display board. Therefore, creating a pattern (input)
There was a problem in that it required a great deal of effort and time.

In other words, the conventional information board control system of this type has a dot matrix operation panel on the center side for creating and inputting patterns to be displayed (mainly characters), and a dot matrix operation panel for creating and inputting patterns to be displayed (mainly characters), and a dot matrix operation panel for inputting patterns such as characters input from this dot matrix operation panel. A monitor unit using, for example, a magnetic reversal element or a CRT, which displays in a dot matrix array similar to the information board on the terminal side, which will be described later.
and an information board control device (hereinafter referred to as MC) having a transmission control section for transmitting the dot pattern data input by operating the operation panel to the terminal side, and transmitting the dot pattern data to the terminal side. A controlled device (hereinafter referred to as SC) has a transmission control function that receives pattern data in bit serial mode, and receives ON/OFF signals for display elements in bit parallel mode from this SC in units of a predetermined dot matrix (for example, 15
The structure includes a large free pattern information board that displays a dot pattern (x16 dots/character).

In a conventional information board control system with such a configuration, when displaying and outputting a pattern consisting mainly of characters including kanji, buttons with lamps for inputting display dots arranged on the dot matrix operation panel of the MC are used. Operate and input the character pattern to be input one dot at a time. Once the pattern for one character has been created, check this on the monitor and input the next pattern one dot at a time in the same way. go. And create (input) the string pattern to be displayed
When the pattern data is completed, the pattern data is transmitted to the terminal side in bit serial mode via the transmission control section. The pattern data transmitted to the terminal side is SC
After the signal is received and stored, it is sent as a display drive signal (lamp on/off signal) of a predetermined dot matrix (for example, 15×16 dots/character) to a large free pattern information board, where it is enlarged and displayed.

In this way, in the past, character patterns to be displayed had to be set one dot at a time, which placed a very heavy operational burden on the operator, and required a great deal of effort and time to create (input) the patterns. was occurring.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information board control system that can easily and quickly create (input) a character pattern to be displayed.

[Summary of the invention]

The present invention effectively utilizes a functional unit that handles standard font character patterns (e.g., 24 x 24 dot matrix structure) used in systems with kanji processing functions such as Japanese word processors. After obtaining a standard font dot matrix character pattern from the input character information to be displayed, convert this standard font character pattern into a degenerate dot matrix character pattern to match the display dot matrix of the information board. The converted degenerate mode character pattern is transmitted to the terminal side and displayed on the information board. This results in
Desired character patterns including Chinese characters can be input easily and quickly without inputting character patterns to be displayed dot by dot.

The operation of one embodiment will now be described with reference to FIGS. 1 and 2. Operator uses keyboard 101
By referring to the book above, selecting a character to be displayed on the information board 110, and operating the data key corresponding to that character, the character code unique to that character is received by the CPU 104. CPU104
When it receives this character code, it extracts the corresponding character pattern (24×24 dot matrix) from the character pattern storage area in the external memory 105 according to the code contents, and further converts the extracted character pattern into a degenerate dot matrix structure. (15 x 16 dot matrix) character pattern, and the converted character pattern is internalized together with the character pattern before conversion (character pattern in standard font).
Store in RAM. Furthermore, the CPU 104
The character patterns before and after conversion stored in the RAM are read out and sent to the monitor unit 102 to be displayed on the monitor screen. After confirming from this monitor screen that the specified character has been correctly input, the operator refers again to the book on the keyboard 101, selects the next character, and specifies it by key operation. In this way, the operator
While checking the character pattern displayed on the display screen of the monitor unit 102, the characters to be displayed on the information board are input in sequence by key operations on the keyboard 101, and the input of the character string to be displayed is completed. In this case, it is determined whether or not there is a character pattern whose pattern shape should be modified among the character string patterns in degenerate mode displayed on the monitor screen, and if there is a character pattern whose pattern shape is desired to be modified, The character pattern to be corrected is displayed in enlarged size on the monitor unit 102 by operating the function key, and dot correction is performed using a light pen. By this dot correction operation, the inside of the CPU 104 is
The corresponding character pattern stored in the RAM is dot-corrected, and in conjunction with this, the corresponding character pattern displayed on the monitor unit 102 is also dot-corrected. If the degenerate mode character string pattern displayed on the monitor unit 102 has the desired display form, the operator then operates the function keys on the keyboard 101 to give an instruction to transmit the character string pattern. . As a result, the degenerate mode character string pattern stored in the internal RAM of the CPU 101 is transmitted to the communication control adapter 106, modem 107, and communication line 1.

The bit serial mode character string pattern data transmitted to the terminal side is received by the SC 109 and stored in an internal storage section with a bit arrangement that follows the dot matrix arrangement of the information board 110. Furthermore, based on the contents of each bit of the character string pattern data in this storage section, the information board 110
lamp drive signals are generated. Each lamp on the information board 110 is controlled on and off by this lamp drive signal, and characters according to the character string pattern data transmitted from the center side are enlarged and displayed on the information board 110.

In this way, the character string information selected by the operator is enlarged and displayed on the information board 110. Therefore,
The operator no longer needs to input the character pattern to be displayed one dot at a time while considering the form, but can simply operate the keyboard 101, specify the desired character, and make dot corrections as necessary. As a result, the task of creating (inputting) a character string to be displayed is greatly speeded up and facilitated.

[Effects of the Invention] As detailed above, according to the information board control system of the present invention, characters to be displayed on the information board are selected using the keyboard, and a dot matrix in a standard font is created from information specific to the selected character. By obtaining a character pattern, converting the character pattern into a character pattern having a degenerate dot matrix structure so as to match the display dot matrix of the information board, and obtaining a drive signal for the information board,
