Description

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 units of predetermined dot marks.

[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 screen, an operator must input the pattern data to be displayed on the display screen one dot at a time at the center. /J? There has been a problem in that creating (inputting) a turn requires 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 the notation turns (mainly characters) to be displayed, and a dot matrix operation panel for inputting the characters input from the dot matrix operation panel. The 4 turns are displayed in a dot matrix array similar to the information board on the terminal side, which will be described later, using a monitor unit using, for example, a magnetic reversal element or a CRT, and the dot and turn data input by operating the operation panel mentioned above. An information board control device (hereinafter referred to as MC) having a transmission control unit for sending data to the terminal side is installed, and the terminal side has a transmission control function for receiving the transmitted bit serial mode pattern data. Controlled device (hereinafter referred to as S
C), and from this SC) z? In the parallel mode, a large free pattern information board or the like is arranged to receive on/off signals of display elements and display dots and turns in predetermined dot matrix units (for example, 15×16 dots/character).

In a conventional information board control system with such a configuration, when displaying and outputting 4 turns mainly consisting of characters including kanji, the display dots arranged on the dot matrix operation panel of the MC are equipped with rungs for inputting display dots. Operate the buttons to input the character pattern to be input one dot at a time. When you have finished creating a ・zo turn for one character, check this on the monitor and repeat the same for the next ・zo turn. Input one dot at a time. When the creation (input) of the character string/turn to be displayed is completed, the turn data is transmitted to the terminal side via the transmission control section in bit serial mode. The guitar data transmitted to the terminal side is received by the SC, stored, and then converted into a predetermined dot matrix (for example, 15×
16 dots/character) display drive signal (lamp on/
It is sent as an off signal to a large free pattern information board and displayed enlarged.

In this way, conventionally, four turns of characters to be displayed are displayed in one
Since the settings have to be made dot by dot, the operational burden placed on the operator is extremely high, and the creation (input) of the data requires a great deal of effort and time.

[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 characters and turns of standard fonts (for example, 24 x 24 dot matrix structure) used in systems with kanji processing functions such as Japanese word processors. After obtaining the dot matrix characters and arm turns of the standard font from the character information to be displayed inputted by keypad operation, the characters and arm turns of the standard font are degenerated to match the display dot matrix of the information board. The degenerate mode character pattern is then converted into a dot matrix character f-turn, and the converted degenerate mode character pattern is transmitted to the terminal and displayed on the information board. As a result, it is possible to easily and quickly input desired characters and letters, including kanji, without having to input the characters and base turns to be displayed dot by dot.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing the configuration of the entire system. In the figure, 101 to 107 constitute components on the center side, and 101 is a keyboard for inputting character string information consisting of characters such as kanji and kana characters to be displayed on the information board described later. Here, a book mat type keypad is used, which uses a book for input with various characters, symbols, etc., including kanji, marked on each member. In this key date 101, in addition to the data key (character input key), arbitrary characters and turns are extracted from the lower part of the character string that has already been manually inputted and degenerated, and expanded to the monitor section described later. A plurality of function keys are provided, including a function key for displaying the degenerated character string pattern and a function key for instructing transmission of the character string pattern to display the degenerated character string pattern on the information board on the terminal side. 4 lights are provided for specifying the coordinates for correcting the character/mother turn enlarged in the section. Reference numeral 102 converts the characters inputted from the keyboard 101 into a dot matrix format using a standard font (here, 24 x 24 dots/
character pattern) and a dot matrix structure (here, 15X
16 dots/character) characters・! The character pattern according to the degenerate mode is displayed and output in each turn.

FIG. 2 is a conceptual diagram of the operation in one embodiment.

The operation of one embodiment will now be described with reference to FIGS. 1 and 2. When the operator refers to the book on the keyboard 101, selects a character to be displayed on the information board 110, and operates the data key corresponding to that character, the character code specific to that character is received by the CPU 104. It will be done.

When the CPU 104 receives this character code, it extracts the corresponding character/arm turn (24×24 dot matrix) from the character pattern storage area in the external memory 105 according to the contents of the code, and further converts the extracted character pattern into a degenerate dot matrix. The character pattern is converted into a character pattern having a matrix configuration (15×16 dot matrix), and the converted character pattern is stored in the internal RAM together with the character pattern before conversion (the character pattern in the standard font). Further C
The PU J 04 reads each character pattern before and after conversion stored in the internal RAM, and displays it on the monitor unit 102.
and display it 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 manner, the operator sequentially inputs characters to be displayed on the information board by operating keys on the key bead 101 while checking the character pattern displayed on the display screen of the monitor section 102. When you have finished inputting the character string to be displayed, check whether there is a character or turn whose shape you want to modify among the degenerate mode character string patterns displayed on the monitor screen. If there is a character pattern that you want to judge and modify, use the function keys on the keyboard 101 to display the character or pattern you want to modify in enlarged size on the monitor section 102, and use the light button to make dot modifications. Let's do it. This dot correction operation requires CPU
The corresponding character/turn 2 stored in the internal RAM of 104 is dot-corrected, and the corresponding character pattern displayed on the monitor section 102 is also dot-corrected accordingly. If the degenerate mode character string/main turn displayed on the monitor unit 102 has the desired display form, the operator then operates the function key of the key date 101 to transmit the character string pattern. give instructions. This allows the CPU
The degenerate mode character string pattern stored in the internal RAM of 10I is transmitted to the terminal side in bit serial mode via the communication control adapter 106, modem 107, and communication line 108. The character string no-turn data in the bit serial mode transmitted to the terminal side is received by the 5C 109 and stored in an internal storage section with a bit arrangement according to the dot matrix arrangement of the information board 110. Furthermore, a lamp drive signal for the information board 110 is generated based on the contents of each bit of the character string pattern data in this storage section.

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 does not have to input the character pattern to be displayed one dot at a time while considering the form, but simply operates the key yN-dot 101 to specify the desired character. Since you can make dot corrections accordingly,
The task of creating (inputting) a character string to be displayed is greatly speeded up and facilitated.

〔Effect of the invention〕
