Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a variable information board device installed on a road or the like to transmit information to an unspecified number of people, and in particular to one in which the information content can be easily changed. It is.

[Prior art]

Conventionally, information boards installed on roads to convey necessary information to drivers have been printed on a single roll-shaped curtain in advance with several types of content to be displayed, and the necessary information has been selected from among these types. However, small incandescent light bulbs or magnetic reversal plates are arranged as display elements on the display board, the display order is set on the program timer, and the R in the information controller is set according to this display order.
It read and displayed the contents written in OM.

However, with such conventional devices, if you want to change the display content or the display time, it requires extensive modification work, and these changes are not easy, especially when the display boards are installed over a wide area. It wasn't a big deal.

[Object and structure of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a variable information board device that allows the display contents of a display board to be easily changed.

To achieve such an object, the present invention displays data stored in a portable memory board with a clock function at predetermined time intervals by controlling the clock function, and when the display contents need to be changed. , which rewrites the data on the memory board. Hereinafter, the present invention will be described in detail using drawings showing embodiments.

In the figure, 1 is an information board controller, 2 is a portable memory port with a clock function, 3 is an information board, 4 is a pillar, 5 is a communication line consisting of a batting line or radio, and 6 is a central control unit. The information board controller 1 is housed in a waterproof case and is attached to a pillar 4.
Further, the memory board 2 is inserted into the information board controller 1.

FIG. 2 is a block diagram of a device for writing data to the memory board 2, where 7 is a writing device, and 8 is a data manual device that can create display contents while looking at the screen, and is composed of, for example, a personal computer.

FIG. 3 is a block diagram of the memory board 2, in which 21 is a microprocessor, 2) is a standard clock, 23 is a memory circuit including RAM, 24 is a communication control section that controls data writing, and 25 is a light emitting diode. A light emitting element, 26 a light receiving element consisting of a light receiving diode, 27 a power supply section, 28
is a power supply terminal. The power supply unit 27 is provided with a battery (not shown) that protects the memory of the memory circuit 23 and drives the standard clock 2), so that even when the memory board 2 is moved alone, the stored contents of the memory circuit 23 and the standard The operation of clock 2) is guaranteed.

FIG. 4 is a block diagram of the information board controller 1, in which 11 is a microprocessor, 12 is a communication control section, 13 is a transmitter/receiver section, 14 is a temporary storage circuit, 15 is a light emitting element consisting of a light emitting diode, and 16 is a light receiving diode. A light receiving element consisting of 1
Reference numeral 7 designates an output terminal for transmitting data for display, and reference numeral 18 represents an input/output terminal for outputting external signals.

Note that when the memory board 2 is inserted into the information board controller 1, the light emitting element 25 which is a photoelectric conversion element of the memory board 2
The light-receiving element 26 faces the light-receiving element 16 and the light-emitting element 15, which are photoelectric conversion elements of the information board controller 1. Similarly, when the memory board 2 is inserted into the writer 7, The photoelectric conversion element of the memory board 2 and the photoelectric conversion element of the writer 7 are arranged to face each other for optical spatial connection. The microprocessor 21 of the memory board 2 and the microprocessor 11 of the information board controller 1 are for overall control of each part within these devices.

The operation of the device configured as described above is as follows.

When the memory board 2 is inserted into the writer 7, the microprocessor 21 is connected to the writer 7 via the power supply terminal 28.
- Power is supplied to all of the communication control units 24. here,
When the current correct time is entered from the data input device 8,
Since this time information is supplied to the memory board 2 via the photoelectric conversion element, the communication control unit 24 of the memory board 2 controls the microprocessor 21 to calibrate the time of the standard clock 2). Next, the display contents are input while looking at the screen of the data input device 8, and the display contents are input together with the button number and display time.

Next, the memory board 2 into which the display contents have been input in this manner is inserted into the information board controller 1. As a result, the display content of the memory board 2 is selected in accordance with the time of the standard clock 2), and the selected data is transmitted to the information board controller 1 via the memory board 2 and the photoelectric conversion element of the information board controller 1. The signal is supplied to the communication control unit 12. Then, the communication control section 12
causes the supplied data to be stored in the temporary storage circuit 14, and the data stored here is output as a display signal)] terminal 17
Since the selected information is supplied to the information board 3 via the information board 3, the selected information is displayed on the information board 3. Figure 5 is 64 dots vertically x 6 horizontally.
This is an example in which information supplied by a four-dot display element is displayed.

When the time elapses, the standard clock 2) selects the next display content, so data corresponding to the next display content is read from the memory circuit 23, and the content a written in the temporary storage circuit 14 is rewritten. As a result, a display different from the previous one is displayed.

In this way, necessary information is normally read out from the memory board 2 in sequence according to the time of the standard clock 2), and the information is displayed. However, if an emergency situation occurs and you want to suddenly change the displayed content, the communication line 5 from the central control device 6
When data corresponding to the display content to be changed is transmitted via the
3 and detected. Then, this detected signal is supplied to the microprocessor 11, so that the microprocessor 11 preferentially rewrites the received data with the stored content of the circuit 14 and displays it. Note that it is not necessary for all information board controllers 1 to have the function of changing the display contents based on instructions from the central control device 6, and only those installed in particularly important locations may be sufficient. In addition, when trying to change the display content that is already displayed, either collect the memory board 2 and insert it into the writer 7 again to rewrite the data, then return it to the information board controller 1, or insert a new one. All that is required is to write data to the memory board 2 and replace it with the memory board 2 that is already in use. Furthermore, since data is exchanged between the memory board 2 and other devices using optical space connections,
Even in places with poor environmental conditions, there is no risk of accidents such as poor contact.

〔Effect of the invention〕

As explained above, in this invention, the data stored in the memory port is read out and displayed under the control of the clock function, so the display content can be changed by simply changing the content stored in the memory board. If it is connected to a central control unit via a communication line, it has the effect that in an emergency, the display contents can be changed under the control of the central control unit located far away from the information board controller 1.
