The operation of the device of the present invention will be briefly explained. In Figures 1 to 4, when a passing vehicle approaches the entrance of a toll road,
A transmission request signal (data 1) is issued from the on-road device 42 to the on-vehicle device (contactless card) 41.

That is, in FIG. 2, a transmission request signal from the transmission signal/time storage circuit 28 to the single-mounted device B is modulated by the modulation circuit 29 and amplified by the amplifier circuit 210.

Through the antenna 21, the in-vehicle device (contactless card) shown in Figure 3

is received by the amplification circuit 22, and is amplified by the demodulation circuit 23.
The received data is demodulated, decoded by the decoder circuit 24, and stored as in-vehicle device (non-contact car r) information K in the received data storage circuit. Next, a data transmission request signal (polling signal) (data 3) is sent from the subcenter data processing device #43 to the roadside device 42.

Then, the ID number of the in-vehicle device (contactless card) is stored in the received data storage circuit 25 of the on-road device, and this information (data 4) is stored in the received data storage circuit 25 of the on-road device. Due to the polling signal from
6, the data is sent to the data processing device of the subcenter. Thereafter, this data (data 5) is automatically transferred to the data processing device 46 of the subcenter on the main line. The data at this point is the number of the entrance toll gate that the vehicle entered, and the time when the vehicle entered the entrance toll gate.

and ID number of the vehicle.

When a vehicle is driving on a toll road, the on-board device on the main line of the toll road (
When the vehicle reaches the installation position of the contactless card 44, a transmission request signal (data 6) is sent from the road device 45 to the on-vehicle device (contactless card) 44. The operation of sending a signal from the on-road device to the on-vehicle device is the same as the operation at the entrance tollgate described above. After that, in-vehicle device (contactless card) 4
Data (data 7) is transmitted from 4 to the road device 45.

The data in this case is the ID number of the in-vehicle device (contactless card). Next, a transmission request signal (polling signal) (data 8) is sent to the roadside device 45 from the data processing device [46] of the subcenter.

For this reason, data (data 9) is sent from the roadside device 45 to the subcenter data processing device 46.

The data at this point is the data at the tollgate entrance (data 4
) is the same ID code. The ID code of the vehicle is already stored in the data processing device 46 of the sub-center, and this stored data is compared and verified with the data stored in the roadside machine 45, and if they match, the sub-center Information about the vehicle's ID code, subcenter (entrance tollgate) number, and entry time (entrance tollgate) stored in the data processing device 46 of the center is transferred to the data processing device 49 of the subcenter.

As the vehicle progresses and reaches the exit of the toll road, a transmission request signal (data 77) is sent from the on-road device 48 to the on-vehicle device (contactless card) 47. The operation of sending a signal from the on-road device to the on-vehicle device is the same as the operation at the entrance tollgate described above.

Thereafter, data (data 12) is transmitted from the on-vehicle device (contactless card) 42 to the road device 48. The data in this case is the ID number of the in-vehicle i (contactless card). A transmission request signal (polling signal) (data 13) is sent to the road device 48 from the data processing device 49 of the subcenter. For this reason.

The ID code (data 14) of this vehicle is sent from the roadside device 48 to the data processing device 49 of the subcenter.

The subcenter data processing device 49 installed at the exit has ID code 0, subcenter (entrance tollgate) number, and entry time (entrance tollgate) sent from the subcenter data processing device 46. At the time when this TL Yuzu ID number is sent from the machine 48 to the subcenter data processing device 49, the subcenter data processing device 4
9, the toll amount for one vehicle is calculated. After that, this data (data J5) is transferred to the data processing device 4 of the center.
Transferred to 10. The data in this case are subcenter (entrance toll gate) No. 16, ID code, entry time (population toll gate), exit time (exit toll gate), and calculated toll amount.

[Effects of the Invention] Since the apparatus of the present invention is configured as described above, it produces the following effects.

1. When building a toll collection system for a toll road using an AVI system, building a toll collection system for the entire toll road with one data processing device W would require a data processing device with enormous processing capacity. By employing a data processing device of a subcenter connected to a center like the device of the present invention, data is transferred between subcenters installed at the location where the vehicle is traveling as the vehicle travels.

Toll payments can be made using a data processing device installed at the exit location of the vehicle.

2. By transmitting this fee settlement data, ID number, and money to the center's data processing equipment, system construction can be simplified and costs can be reduced because a huge amount of data processing equipment at the center is not required. It can also be done cheaply.
