[Detailed Description of the Invention] "Industrial Application Field" This invention applies to various vehicles such as trains, buses, and taxis.
When information requester 1 is received, Ilr information 1 is displayed in the information requester vehicle.
Regarding the Yudatsu device.

``Prior Art'' Conventionally, various types of bosses have been displayed on various vehicles such as trains, buses, and taxis for the purpose of promoting goodwill.

The bosk is placed in a frame 1), suspended from a support, and installed inside the car.

``Problems to be solved by the invention'' When using a bosk as an advertising medium, the bosk must be replaced in order to change the advertising content.

For this reason, there is a drawback that replacing the bossk requires a lot of manpower and time.

In addition, because the advertising contents of the Bosk are fixed, once passengers see the Bosk, they are no longer interested in it, and even though they occupy a portion of the interior of the train, the advertising efficiency is low.

In addition, conventionally, there is no means for transmitting and displaying information in a car in real time, not only for advertisements and advertisements.

For example, it does not have the ability to inform passengers of the latest news, weather forecasts, baseball game results, or the progress of a game.

The purpose of this invention is to notify the passengers of various services in real time? S information transmission equipment is provided.

``Means for Solving the Problems'' In the present invention, an information transmitting device that transmits information using radio waves is installed at a predetermined position on a vehicle travel path.

According to the configuration of the present invention, each time the vehicle passes near the information transmitting device, the memory contents of the memory device mounted on the vehicle are rewritten,
Along with this, the contents of the display are updated.

Therefore, according to this invention, is it possible to provide the latest information to a moving vehicle? 1
The more passengers are able to improve their services, the more they can improve their service to passengers.

In addition, advertising posters (advertisements can be displayed one after another) without having to be installed in the car. Therefore, since the advertising content is rewritten one after another, various advertising contents can be displayed one after another on one display. Can be done.

Therefore, the efficiency of advertising can be improved.

``Embodiment'' Figure 1 (2) shows an embodiment of the present invention. In this example, the vehicle χ railway is 9 trains. The reference numeral 11100 is a vehicle, 200 is a running path for this vehicle 100, and 300 is a running path for this vehicle 100. The required position of this travel path 2000 (- indicates the installed information transmitting device. This information transmitting device 300 is connected to a telephone line 40, for example.
The main station 500≦2 is connected with the main station 500 such as 0, and the latest information is transmitted from the main station 500 to the information transmitting device 300.

For example, the information transmitting device 300 may be installed at each station that the train arrives at every 10 minutes of the train's operating time, or the information transmitted from the main station 500 may be divided into two along the line that the train passes every 10 minutes. Information is transmitted via weak radio waves.

The vehicle 100≦2 has a receiver 101 as shown in FIG.
A storage device 10 that stores information received by this receiver 101
2, and a plurality of displays 103 for displaying information stored in the memory 102.

The storage device 102 is, for example, a part of a RAM configured in the microcomputer 104'. You can use it. Tip 1] As is well known, the microcomputer 104 includes a central processing device 105 and a ROMI O6 that stores programs that operate this central processing device in a predetermined order.
And the program written in ROM106? A storage device 102 consisting of a memory that can be written and read at any time and is used to temporarily store various data necessary for execution.

Input boat 107. The output boat 108 (can be configured by two).

The storage device 102 is provided with a storage area corresponding to the number of pixels of one display device 103 in addition to the storage area necessary for operating as a micro combinator, and this storage area is provided with a storage area for the storage area corresponding to the number of pixels of one display device 103.
The Q18i received at 01 is memorized. This storage operation is executed by detecting an information start signal sent from the information transmitting device 300, for example.

T) Radio waves 301 transmitted from the information transmitting device 300
As shown in FIG. 3, an information start signal 302 is followed by an I
The W report 303 is sent, and when the information 303 is finished, the I
A ii-report start signal 302 is transmitted, and this is repeated.

This repetition cycle AT depends on the amount of the t* signal 303, but can be, for example, about several 100 microJ seconds to several tens of seconds.

A microcomputer 104 mounted on the vehicle usually reads out information written in the memory 102 and outputs it to the output boat 10.
Information 303 to the branch 109 through 8? A display device 103 is output and placed at a desired position in the vehicle via a turnout 109.
Refresh memo! The operation of transferring information 303 to J103A is repeated.

The display 103 is, for example, a plasma display.

Alternatively, a flat display such as a liquid crystal display is used.

However, if there is no space restriction, 1. for cathode ray tube display. ) and can be attached to the wall inside the car. Each display 10
3 has a built-in reflex memory 103A, and a microcomputer 104 is built into this reflex memory 103A.
By writing the information 303 sent from the reflex memory 103 and reading it out in synchronization with the scanning of the Aa' display 103, characters, figures, etc. are displayed on the display 103.

If1 sent from microcombi and user 104
The information 303 is written to the refresh memory 103A during the vertical retrace interval of the display 103. In other words, the microcomputer 104 sends out data for one horizontal scanning line, for example, in the vertical retrace interval ≦2 of the display 103, and asks for data? Write to the reflex memory 103A. Therefore, the data of each horizontal scanning line of the display 103 is displayed for each vertical retrace interval (
The data is transferred from the storage device 102 of the second microcomputer 104 and written to the refresh memory 103A, and one screen worth of information is rewritten.

The data transfer operation from the storage device 102 to the refresh memory 103A is always carried out in advance (1) Usually, the same data is repeatedly written to the refresh memory 103A (2).
The same screen is displayed until the contents of the memory device 102 are rewritten.

When the receiver 101 enters the field strength range of the information transmitting device 300 and receives the information start signal 302, the microcomputer 104 detects this signal 302 and transmits the ROMI 06.
Execute the information rewriting program χ stored in . The information rewriting program consists of an operation of converting serial digital data sent from the receiver 101 into parallel data of, for example, 8 bits as one byte, and an operation of writing this parallel data into the memory 102.

While the information start signal 302 is being received, the microcomputer 104 executes the information rewriting program and rewrites the information stored in the storage device 102 with the newly sent information.

When the information start signal 302 is not received, the microcombiator 104 returns to the normal data transfer program and starts transferring new data to the 1 display 103. When the transfer of new data is started, the display screen is rewritten to display the new data in order from the top, for example.

In the case of a train, one receiver 101 and one microcomputer 104 are installed per train, and data is distributed from one microcomputer 104 to a display 103 installed in each vehicle through a turnout 109. Alternatively, it is conceivable to install two receivers 101 and a microcomputer 104 for each vehicle or each display.

According to the former configuration, only one receiver 101 and one microcomputer 104 are required, so it is economical in this respect.However, since data must be distributed to each vehicle, the cost of wiring and one branch are required. This has the disadvantage that the capacity of the container 109 becomes large.

On the other hand, when the receiver 101 and the microcomputer 104χ are provided for each vehicle or each display, the receiver 1
Although the number of microcomputers 01 and microcomputers 104 increases, the wiring connecting the microcomputers 104 and the display 103 and the branch 109 are no longer necessary, so the cost in this respect is reduced. Which configuration to adopt is determined based on economic efficiency.

In addition, if the information transmitting device 300 at the station is configured to rewrite information while the first train is stopped, the time when the first train is in the electric field strength range of the information transmitting device 300 because the first train is stopped. can be harvested for a long time.

Therefore, the information transmission speed can be set relatively low, and in this respect, the incidence of signal errors can be reduced. Is it possible to rewrite again? Since it can be used for a long time, for example, the storage device 102 has a storage capacity for several screens, transmits information for several screens in one data rewrite, and switches the information for several screens at regular intervals. It is possible to configure the system so that it is displayed.

In the above-described embodiments, the present invention is applied to railways, but it can also be applied to other types of vehicles such as passes, taxis, etc.

"Effects of the Invention" As explained above, according to the present invention, various types of information can be transmitted to a vehicle, and the information can be displayed on the display 103.

Therefore, advertisements, nice messages, etc. can be sequentially displayed in the train every 10 minutes, for example, so that passengers can conveniently know the latest information while staying in the train.

In addition, the operator of the vehicle can earn advertising revenue, which has a large economic effect. Also, what are the contents of many displays 103? Since it can be rewritten without manual intervention, a large number of fir reports can be displayed in a short period of time. Therefore, if used as an advertisement, the advertising effect will be extremely large.

Also, what is the radio wave strength of the information transmitting device 300? Since the use of weak radio waves eliminates the need for large-scale transmission equipment, the information transmitting device 300 can be installed at low cost. In addition, since weak radio waves are used, there is no interference with other communication systems, so operation is easy.
