However, the car telephone system requires a complicated system, and the car telephones are very expensive, so they cannot be used universally. For this reason, even if a situation arises where a carrier needs to contact the vehicle in an emergency, if the current location of the vehicle is unknown, there is no other option than to wait for the crew to contact them. Furthermore, even if you try to transmit information to a vehicle equipped with a car phone, etc., there is a risk of eavesdropping as electromagnetic waves with a certain frequency are propagated over a wide area in wireless communication, and only limited information can be transmitted. There wasn't.

SUMMARY OF THE INVENTION Therefore, the present invention provides an information transmission device that has a simple and inexpensive configuration, can quickly transmit desired information to vehicles passing on the road at the end station, and can sufficiently ensure the confidentiality of the transmitted information. The purpose is to

It will be done. As a result, the crew under the vehicle will know that there is a message from the terminal station.

Therefore, if there is a message, the driver under the vehicle parks in the service area A near R, and inserts the owner's unique card C, such as a separately paid card or credit card, into the card reader of the roadside information exchange terminal 30. Insert into 34. Then, this card reader 34 reads the card C.
The card number recorded in the card number is read, and the control unit 35 transmits ID number information S5 corresponding to the card number to the message information processing device 20. In the message information processing device 20, the message information search section 23 is searched by the search circuit 25, and the message information S2 corresponding to the ID number information S5 is retrieved. This message information S2 is displayed on the display section 33 of the roadside information exchange terminal 30 and simultaneously printed out by the printer section 32. In this way, message information from the terminal station is transmitted to the crew member under the vehicle.

It is displayed on the display unit 13 of 110. Further, this tracking information S6 is stored in the storage section 14, and is recorded by the printer section 12 at an appropriate time by operating the console section 11.

As described above, according to this embodiment, when an attempt is made to contact a vehicle traveling on the expressway from a terminal station such as an office to which the vehicle belongs, the information exchange terminal 10 on the terminal station side is By operating and inputting ID number 1 and message information, the crew member of the vehicle T is informed that there is a message. Meanwhile, the crew under the vehicle concerned is in service area A.
Park your car in this area, and use the roadside information exchange terminal m30 installed in this area A to enter the card number recorded on the unique card C to display or print the message from the terminal station on the display.・You can know by.

Also, 1st. Wireless communication is used between the second ground transducer 50, 60 and the onboard transducer 70, but since it is used only in a limited area, the system can be configured with a single frequency, and other There is no risk of radiating radio waves into other systems and causing interference. Therefore, since it does not require several channels unlike a car phone, it can be realized with a simple and inexpensive configuration. However, since the roadside information exchange terminal 30 can only be used by specific users who own separate payment cards,
Confidentiality of message information is ensured.

Furthermore, since the tracking data under the vehicle is transmitted to the terminal station in real time, the driving situation under the vehicle can be accurately grasped, and the data can be edited in daily or monthly reports by operating the console unit 11. It is also possible to display it on a display or print it out.

By doing so, business management can also be simplified.

Note that the present invention is not limited to the above embodiments.

For example, in the above embodiment, the terminal station is one station and the roadside i-device is also installed at one place, but it is also possible to share the message information processing device t20 and connect multiple others. Of course it's good. Further, the installation location of the data communication control device 40 is not limited to the service area A or the like, and is not particularly limited as long as a communication line can be installed. In addition, various modifications can be made without departing from the gist of the present invention.

(Effects of the Invention) As described in detail above, according to the present invention, desired information can be quickly transmitted to vehicles passing on the road at the end station side with a simple and inexpensive configuration, and the transmitted information can be kept confidential. Therefore, it is possible to provide an information transmission device in which security is sufficiently ensured.
