Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless recording medium processing apparatus applied to a toll collection system for collecting tolls on toll roads using a wireless storage medium such as a wireless card.

[0002]

2. Description of the Related Art Conventionally, on a toll road such as an expressway, an automated system has been considered which uses a wireless card to collect a usage charge (a toll).

The wireless card used in this kind of automated system has a battery inside and operates by the power of this battery.

In the above-mentioned automated system, for example, a system that collects tolls on toll roads, at the time of entry (at the time of entry to the toll road), a wireless card mounted on a vehicle is used to enter an entry position (internet information). Name), vehicle type, etc. are stored, and when entering, this input information is read to calculate and collect charges. By performing such transactions using wireless communication, etc., it becomes possible to eliminate the obligation to stop the car at the tollgate (non-stop collection), automate the toll collection and unmanned, and make the expressway smoother. It is trying to promote use.

[0005]

A conventional highway toll collection system will be described with reference to FIG. In the figure, L is a separation area for separating adjacent lanes.
A processing device 11 is installed at approximately the center of the separation area L. An antenna 12 connected to the processing device 11 is installed on the vehicle entrance side of the separation area L.

The transmittable and receivable range of the antenna 12 is as shown by A and B in the figure due to the directivity.
It is a left-right object across.

The processing device 11 controls the antenna 12 so as to skip the interrogation radio wave from the antenna 12 and determines the data transmitted from the radio card mounted on the vehicle in response to the interrogation radio wave. A predetermined process is performed. For example, as a response to the above-mentioned inquiry radio wave, an available card
Information such as balance, card ID number, vehicle type, entrance toll gate, etc. is transmitted from the wireless card, and the information is input to the processing unit 11 via the antenna 12.

The processing device 11 is a vehicle type and an entrance toll gate ID.
The current usage charge is calculated, and the new usage balance is calculated by subtracting the current usage amount from the availability balance. These are stored in the memory of the wireless card together with information such as the date of use, the amount of money used, the exit toll gate ID, etc. via the Anna 12.

By the way, since the antenna 12 transmits the interrogation radio wave to the adjacent lanes with the antenna 12 interposed therebetween as shown in FIG. 6, when the vehicle 13 enters the lane, the antenna 12 is transmitted. Receives a response radio wave from a wireless card mounted on the vehicle 13 and outputs it to the processing device 11.

However, since the transmittable / receivable range of the antenna 12 is symmetrical with the antenna 12 in between, there is a problem that it cannot be determined which lane the vehicle 13 has passed through. Furthermore, it was not possible to count the number of vehicles passing by each lane.

The present invention has been made in view of the above points, and an object thereof is to provide a wireless recording medium processing apparatus capable of accurately determining which lane a vehicle has passed.

Interrogation radio waves are alternately transmitted at intervals of 0.5 seconds (step S1). By alternately transmitting the inquiry radio waves in this manner, the inquiry radio waves transmitted from the adjacent antennas are prevented from interfering with each other.

Then, when the response radio wave to the inquiry radio wave is received from the wireless card 51 mounted on the vehicle,
The processing devices 21 to 22 each perform a matching process. Then, if the data received through the adjacent antennas do not match, the collector takes any action (step S5).

On the other hand, if the two match, it is determined that the vehicle V is passing through a certain lane, the current charge is calculated from the vehicle type and the entrance toll gate ID, and the current balance is calculated from the available capacity balance. The new usage balance is calculated by subtracting the usage amount. Then, processing such as collecting a charge from the host computer account is performed (step S6). Then, these are transmitted to the wireless card 51 via the antenna together with information such as the date of use, the amount of money used, the exit toll gate ID, etc. (step S).
