Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to, for example, a toll road.
A wireless device such as a wireless card is used to charge the toll of vehicles passing through the road.
Road toll collection system that collects money using a container, and
The present invention relates to a wireless device used for this and a road charge processing method .

[0002]

Conventionally, a wireless card (wireless equipment) that is a recording medium is mounted on the vehicle is traveling on a toll road, a system for calculating the toll on the basis of the data recorded in the wireless card, the Read data from wireless card
Write data must be processed one-to-one with respect to
is there. That is, in the conventional system,
Barrier installed at a point to check the passage of vehicles
The order of occurrence of read data from the wireless card
Depending on (the order of vehicles entering the barrier),
Create write data, send it, and write it from the wireless card.
It is assumed that one process has been completed after receiving the result data.
It

For example, as shown in FIG. 6, a wireless card
Vehicles # 1, # 2, ...
After entering, the read data is read by the read antenna 31 in the order of entry.
When it is sent to the barrier processing unit 32 via the
The read data is processed according to the order. Processed
The same data is sent from the processing unit 32 to the light antenna 33.
Sequentially sent to each vehicle in turn, each vehicle's wireless
The card returns the write result data to the processing unit 32.

[0004]

A conventional wireless card is used.
In this system, the vehicle uses the lead antenna 31.
If it passes through the light antenna 33 in the order of passing,
System works normally. However, as shown in FIG.
After completing the processing of vehicle # 1, motorcycle # 3
When the light antenna 33 is reached first after passing 2
Is a wireless card that has read data in conventional systems
Wireless card about to write your card number and data
Because it is different from the card number of
No data is written to the installed wireless card.
Yes. After that, the vehicle # 2 reaches the light antenna 33.
Then, the data is written to the vehicle # 2, and the processing unit 3
2 next tries to send write data to Motorcycle # 3
However, at this time, motorcycle # 3 is already in the effective range for transmission and reception.
It has run out of the area and cannot handle motorcycle # 3.
It becomes Noh. In addition, as shown in FIG.
Vehicle # 4 that passed No. 1 is
Back in front of the light antenna 33
If not, the process is not completed. In this way, conventional
On the stem, the order of vehicles entering and leaving the barrier
If the order does not match, processing is not completed
I have a problem.

Therefore, the present invention is based on a radio mounted on a vehicle.
When the device continuously generates data, the wireless device
The preceding write process to the delay or is not completed
However, subsequent data processing can be completed without omission or omission.
Road toll collection system, wireless device and road
The purpose is to provide a charge processing method .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a road charge according to the embodiment of the present invention .
3 is a top view showing the configuration of the money collection system 10. FIG. This road
The road fee collection system 10 is a wireless card system,
The vehicle 3 equipped with the wireless card (wireless device) 2 as a recording medium is stored in the wireless card 2 by passing in front of the read antenna (first antenna) 11 and the write antenna (second antenna) 13. Data is read and written, tolls are paid
It The read antenna 11 for reading processing and the write antenna 13 for writing processing are installed on the island 9 so as to communicate with the wireless card 2 mounted on the vehicle 3 by a wireless system. The processing unit 12 is the tollgate island 9
Located in the booth installed in the
It is also connected to the light antenna 13 to control them and process transmitted / received data.

FIG. 3 is a block diagram showing the configuration of the processing unit 12 shown in FIG. The processing unit 12 is a CPU 2 that controls the whole.
1. ROM 22 for storing control programs and the like, R for storing vehicle identification data and having a processing queue
An AM 23, a DC power supply 24 that supplies a DC voltage to each unit, and a wireless card interface 25.

Next, the road toll collection system 10 of the present invention.
The operation will be described with reference to FIGS. 1, 4 and 5.

FIG. 4 is a flow chart for explaining the processing procedure in the wireless card 2, and FIG. 5 is a flow chart for explaining the processing procedure in the processing unit 12. The wireless card 2 is a prepaid card and has a unique identification code. The lead antenna 11 is a processing unit 12
The read data transmission request is transmitted (polling) at a constant time interval regardless of the processing (1) in FIG. When the vehicle enters the barrier and enters the transmission / reception effective range of the lead antenna 11, the wireless card 2 installed in the vehicle 3
However, in response to the read data transmission request, the card data such as the remaining amount of the prepaid card and the previously used information is read (step ST10 in FIG. 4). The wireless card 3 transmits the read data to the read antenna 11 (b in FIG. 1 and step ST11 in FIG. 4). The read antenna 11 transmits the read data to the processing unit 12 (c in FIG. 1). Processing unit 1
2 is in a standby state (step ST20 in FIG. 5), and when the read data is received from the read antenna 11 (step ST21 in FIG. 5), the validity / invalidity of the received data, the remaining amount, etc. are checked and the charge is calculated. Then, after deducting the charge from the amount paid in advance, write data is created (d in FIG. 1, step ST22 in FIG. 5), and the write data is registered in the processing waiting queue provided in the processing unit 12. (D in FIG. 1, step ST23 in FIG. 5).

Here, the processing section 12 determines whether or not unprocessed data is registered in the processing waiting queue (step ST24 in FIG. 5). In step 21 of FIG. 5, the processing unit 12 constantly checks whether there is unprocessed data even when the read data is not received. When unprocessed data is registered in the processing queue, the processing unit 12 sequentially transmits the processing queue data as write data to the write antenna 13 (step ST2 in FIG. 5).
5). After transmitting the write data, the processing unit 12 further searches the processing waiting queue for unprocessed data in the processing waiting queue (step ST26 in FIG. 5). When there is unprocessed data (step ST27 in FIG. 5), it is further transmitted to the write antenna 13 as write data. As long as there is unprocessed data, step ST25, ST26, ST27
Is repeated. As soon as the write antenna 13 receives the write data from the processing unit 12, the write antenna 13 sequentially transmits the write data to the wireless card 2 (f in FIG. 1).

When the wireless card 2 mounted on the vehicle receives the write data (step ST12 in FIG. 4), the data is written in the card (step ST13 in FIG. 4).
Read this written data (step ST1 in FIG. 4).
4), the write result data is transmitted to the write antenna 13 (g in FIG. 1, step ST15 in FIG. 4). When the write antenna 13 receives write result data from the wireless card 2 which is within the effective transmission / reception range, the write antenna 13 processes this data.
2 (h in FIG. 1).

When the processing unit 12 receives the write result data from the write antenna 13 (step ST2 in FIG. 5).
8), the write result data is compared with the unprocessed data in the processing queue, and if there is a matching unprocessed data, the corresponding unprocessed data is deleted from the processing queue (i in FIG. 1, step in FIG. 5). ST29). At this point, the processing for the processing-waiting data is completed. As shown in FIGS. 6 and 7, the data writing process can be executed even if the arrival order to the lead antenna 11 and the arrival order to the write antenna 13 of the vehicle are different.

In the case of FIG. 8, since the data remains in the processing queue forever, if the write result data is not received even after the transmission of the write data is repeated for a fixed time or a fixed number of times, it is treated as an error process. Alternatively, it may be deleted from the processing queue.

Further, the processing unit 12 can be provided with a payment processing function for cash, coupon tickets, etc. as well as the wireless card.
