Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic information display board control device, and more particularly to a device for remotely controlling the electronic information display boards of a plurality of terminals from a central location.

When transmitting information from the center to display desired information on the electronic information display boards of each terminal, it is very time-consuming to input characters or figures to be displayed for each block on the display board. The display board can display arbitrary characters and figures, and therefore the display is often changed.

Figure 1 is a graph showing an example of a display board, where A shows one in which blocks 1 to 12 are arranged in one row, B shows one in which 12 blocks are arranged in two rows, and each block is shown in Fig. 2. For example, a light bulb L as shown
They are arranged in 16 columns and 15 rows, and certain ones of them are lit to display letters and figures. Second
The figure shows the character ``Fuku'' displayed by lighting a light bulb. Each block 1 to 12 in Figure 1
The information is displayed as a whole by displaying the information as shown in FIG. 2, respectively. In order to change the content of such display information, inputting display characters and figures for each block at the center is extremely time-consuming. By the way, if such a display board is used on a highway, for example, specific characters such as "per hour" or "kilometers (Km)" are usually used frequently.

Therefore, specific characters, figures, etc. that are used frequently are set in advance in the central storage area, and a pattern number is assigned to each of them.When changing the display information, these characters and figures are assigned that number. If you can display it on the display board of the terminal simply by specifying it, you will only have to enter characters and figures that are not set in the central storage area from the center, which will save a lot of effort. .

This invention was made in consideration of the above-mentioned problems, and its purpose is to create an electronic system that eliminates the need to input patterns in the center each time display information is changed for frequently used characters and figures. An object of the present invention is to provide an information display board control device.

In order to achieve the above object, the present invention includes a free pattern input section for inputting arbitrary characters and figures, a fixed area for storing predetermined characters and figures, and a fixed area for storing characters and figures input from the free pattern input section. A storage unit having a free pattern area for storing information and a terminal area for storing information to be sent to each terminal, and a desired display by combining information selectively read from the fixed area and free pattern area of the storage unit. a pattern selection device for forming information for display and setting such display information at a predetermined position in the terminal area; and a communication control device for transmitting information in the terminal area to each terminal. .

In the above configuration, characters and figures that are frequently displayed on the display board are stored in the fixed area of the storage unit, and when trying to change the display, the characters and figures used in the change display are stored. Among them, only the characters that are not stored in the fixed area are inputted by the free pattern input section and stored in the free pattern storage area of the storage section, and the characters set in the fixed area by the pattern selection device are input. , selectively and sequentially read out necessary characters and figures stored in the figure and free pattern storage areas according to the information to be displayed, and combine the read information to create the desired display information. , and set these pieces of display information at predetermined positions in the terminal area, and each piece of information set in this terminal area is transmitted to each terminal by the communication control device. When trying to change the display in this way, all you have to do is input from the input section only the characters and figures that are necessary during the change display that are not stored in the fixed area and store them in the free pattern area. If characters and figures that are frequently used in display information are stored in a fixed area, the number of characters and figures that must be entered from the input section each time the display is changed can be reduced, reducing the amount of effort required for input. It can be omitted.

Embodiments illustrating the present invention will be described in detail below.

FIG. 3 is a block diagram showing the configuration of one embodiment of the present invention. Reference numeral 21 denotes a storage unit, which has a fixed area 22, a free pattern area 23, and a terminal area 24. The fixed area 22 stores characters and figures that are frequently used on the display board of the terminal, and one character or one figure is stored for each address. This can be incorporated as a printed circuit board during the manufacturing process. The number and type of characters and figures to be stored in the fixed area 22 may be appropriately selected. 25 is a memory buffer, and 26 is a free pattern input section, which has input keys arranged similarly to the arrangement of the light bulbs shown in FIG. 2, and these input keys are designed to light up when each is operated. The pattern input by the free pattern input section 26 is stored in the memory buffer 25. 27 is an address setter with numeric keys, 28 is an address generator,
The address input by the address setter 27 is input to the address generator 28. 29 is an OR circuit; 30 is a memory address; the output signal of the address generator 28 is inputted to the memory address 30 via the OR circuit 29; memory address 3
0 specifies the address of the storage area of the storage unit 21 . A pattern selection device 31 includes a terminal area designator 32 and a storage area designator 33. The designators 32 and 33 each have a numeric key, a specific key 32' that generates a signal indicating that the terminal area is specified, and a specific key 33' that generates a signal that indicates that the storage area is specified. A decoder 34 decodes the signals input by the designators 32 and 33. The output of the decoder 34 is OR circuit 2
9 to the memory address 30. 3
5 is a communication control device; 36 is a modem; information in the memory buffer 25 is sent by the communication control device 35 to each terminal via the modem 36;

Next, the operation will be explained.

When trying to display information on the electronic display board of the terminal or changing the displayed information, only those characters and figures used in the displayed information that are not stored in the fixed area 22 are displayed. Input by operating the free pattern input section 26.
Since the input unit 26 has input keys arranged similarly to the arrangement of the light bulb L shown in FIG.
As shown in the figure, when inputting the character ``福'', the input key corresponding to the position of the light bulb indicated by the black circle in Figure 2 is operated. The operated input key emits light to indicate that the character "Fuku" has been input. This input pattern is stored in the memory buffer 25. On the other hand, the address setting device 27 is operated to set the address of the free pattern area 23 of the storage section 21 . As a result of this operation, a signal of the set address is output from the address generator 28 and inputted to the memory address 30 via the OR circuit 29. Therefore, the memory address 30 specifies the address of the free pattern area 23 set by the address setter 27, and the pattern stored in the memory buffer 25 is stored in this address. This pattern setting section 26 sets the pattern. In this way, necessary characters and figures (plurality) are inputted one after another through the input section 26 and stored at a predetermined address in the free pattern area 23. Also in the free pattern area 23, one character or one figure is stored at one address. After necessary characters and figures are stored in the free pattern area 23, the terminal area designator 32 of the pattern selection device 31 is operated to designate a desired address in the terminal area 24 of the storage section 21 . The signal of the address designated by this designator 32 is sent to a decoder 34,
It is input to the memory address 30 via the OR circuit 29. The designator 32 is provided with a specific key 32' for generating a signal indicating that the terminal area is designated, and after operating this key 32', the address of the terminal area is input. When the memory address 30 receives a signal from the operation of the designator 32, it designates the corresponding address in the terminal area 24. The terminal area 24 has addresses 1 to n corresponding to each terminal. Next, the designator 33 is operated to input the address in the fixed area 22 and free pattern area 23 of the storage section 21 where the characters and figures to be displayed are stored. Designator 33
A specific key 33' is provided for generating a signal indicating that an address for areas 22 and 23 is specified, and an address is input using a numeric key after operating this key 33'. The signal input by the designator 33 is added to the memory address 30, and the memory address 30 is added to the fixed area 22 corresponding to the input signal.
Alternatively, an address in the free pattern area 23 is specified, so that the pattern stored at that address is placed in the already specified address in the terminal area 24. By sequentially specifying the addresses of the fixed area 22 and the free pattern area 23 in which information corresponding to the information part for display is stored according to the characters and figures of the information to be displayed in this way, Information is read from both areas 22 and 23, and these pieces of information are sequentially written to desired addresses in the terminal area 24. In this way, information to be displayed on the electronic display board of a desired terminal is formed at a desired address in the terminal area 24 by combining the information selectively read out from the fixed area 22 and the free pattern area 23. Ru.

The information read from the terminal area 24 is transmitted by the communication control device 35 to a predetermined terminal via the modem 36 and displayed on the electronic display board of this terminal.

In the above operation, the pattern selection device 31 can select each pattern based on the address numbers of the fixed area 22 and free pattern area 23. These address numbers can be pattern numbers indicating the type of pattern.

There is no problem if all characters and figures used for all display information can be stored in the fixed area 22, but if the display information is of various types, all characters and figures can be stored in the fixed area. As a practical matter, it is impossible to store information in
By appropriately selecting frequently used characters and figures and storing them in a fixed area, and inputting other characters and figures into the free pattern area from the input section as necessary, The number of steps required for inputting data from the input section can be considerably reduced. The input of the free pattern area may be performed using an electronic computer or a microprocessor.

Furthermore, the memory in the fixed area is assumed to be unchangeable, and by assembling these with a diode matrix during the manufacturing process and using it as a printed circuit board, it is possible to eliminate the need to provide a protection circuit to prevent the memory in the fixed area from being rewritten.
