Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a method for individually identifying and managing vehicles on expressways, toll roads, toll parking lots, or vehicles entering special zones with permission. This invention relates to a 11L@ identification system that is capable of

(Prior art) This type of conventional vehicle identification system involves mounting an ID plate, which stores an identification (ID) number unique to the vehicle, on the vehicle by affixing it to the vehicle, and then attaching it to the vehicle at checkpoints such as toll gates on toll roads. On-road facilities such as ID play 1-readers installed on roads recognize the ID number stored or written on the ID plate using low-power radio waves, etc., for example, processing the collection of tolls by vehicle type on toll roads, etc. (For example, Traffic Engineering, Vol. 21, No. 2, 26
~page 29).

(Problem to be solved by the invention) However, in the above-mentioned vehicle identification system,
Even if it is possible to read the ID number, it is not possible to confirm whether the ID plate is the one under contract for that vehicle. In other words, it is possible to fraudulently use an ID plate contracted for a small vehicle at a low price and install it on an expensive large vehicle for which the contract is not in place to reduce tolls. Furthermore, ID plates contracted in a prepaid manner, such as a one-time toll, have the disadvantage that the user (driver) cannot know the balance amount or the balance of the number of tolls.

The present invention provides 10 plates that eliminate the above-mentioned conventional drawbacks.
and the provision of vehicle identification systems using it.

(Means for Solving Problem 111) The present invention achieves the above object by storing not only an ID number as a mere numerical string in the storage information of an ID plate, but also information unique to a vehicle such as a vehicle number. This is achieved by a vehicle identification system using an ID plate that stores license plate information independently in a ROM or by setting a constant that converts the information into a constant, and also has a residual information storage section that stores the contract balance or contract frequency balance. .

(Function) According to the present invention, an ID storing a vehicle number etc.
Since a plate is used, unauthorized use is easily detected, and the vehicle number information is stored independently, making it easier to manage fees for each user and storing the information in ROM or constant settings. By accumulating by means.

It is possible to provide information that is stable against external disturbances.

Furthermore, if the fee is paid in a prepaid manner, the user can easily check the amount of the contract balance or the frequency balance.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 is a diagram of the roadside equipment of the system of the present invention to show the concept of the present invention, 21 is an ID plate, and 22
The information stored or written on the ID plate 21 is read by the roadside antenna section 23 using low-power radio waves as a transmission medium, and the information stored or written on the ID plate 21 is read by the vehicle with the vehicle number 24 etc. Information is imaged by the imaging unit 25.

FIG. 3 shows an example of the configuration of the ID plate 21 described above. It has a plate information storage section 27 and a remaining information storage section 27', and the license plate information read out from each, and the information on the balance or the balance toll frequency are combined in the ID information information synthesis and distribution section 28, and a modulated signal is generated and received. The ID plate antenna section 29, the modulation/demodulation section 30, and the ID plate antenna section 31 respond to the reading start signal from the roadside antenna section 23 as shown in FIG. 2 described above. Also ID
The information on the balance or balance frequency received by the plate antenna section 31 is transmitted to the modulation/demodulation section 30, the modulated signal generation/reception section 29,
The remaining information storage section 27' via the ID information synthesis and distribution section 28.
The balance or remaining amount information can be displayed on the display section 33 via a switch 32 provided as necessary, and can be easily confirmed by the driver.

The ID plate 21 has an ID such as a 10-digit numerical string, for example.
License plate information may be added to the D number, and land transportation office code, vehicle model code, vehicle model code by purpose,
The license plate information itself, such as a four-digit serial number, can be the ID number.

FIG. 1 is a block diagram showing the configuration of an embodiment of the system of the present invention. 1 is an ID plate reading section, a roadside antenna section 2, a communication processing section 3. and ID number identification section 4
It consists of Reference numeral 5 denotes a license plate reading section, which is composed of an imaging section 6, an image processing section 7, and a license plate identification section 8.

ID plate reading section 1 and license plate reading section 5
is output to the comparison and verification section 9, and the balance information confirmation section 10 outputted by the comparison is connected to the communication control sections 11 and 11', and the communication control section 11 is further connected to the charge calculation processing section 12.
, and is connected to the illegal traffic handling section 13. Also,
Reference numeral 14 denotes a balance notification section, which is connected to the fee calculation processing section 12 and the communication processing section 3.

In the present invention configured in this manner, the ID plate reading section 1 is configured to read an ID plate 21 mounted on a vehicle 22 and a roadside antenna section 2 (corresponding to 23 in FIG. 2) as explained in FIG. For example, ID number information and balance information are received by a wireless communication using radio waves or the like as a transmission medium between The license plate reading unit 5 includes a vehicle type code, a 4-digit serial number, etc., and an imaging unit 6 (corresponding to 25- in Figure 2) images a license plate 24 (Figure 2) attached to a traveling vehicle. Then, the image processing section 7 causes the license plate identification section 8 to identify the vehicle model code, four-digit serial number, etc., and transmits the identification result to the above-mentioned comparison and verification section 9 as license plate information. The ID number identification unit 4
If they match, it is determined that there is no fraud, and the information is sent to the fee calculation processing section 12 via the communication control section 11, where the fee calculation process is performed according to the required vehicle type classification, etc. In addition, if the above comparison does not match, it is determined that there is fraud and the unauthorized traffic response unit 13 is notified via the communication control unit 11', and necessary processing such as closing the gate or taking an image of the illegally passing vehicle is performed. do.

In this way, the present invention detects unauthorized use of the ID plate by comparing the ID plate information and the vehicle number to which it is originally attached in real time.

In addition, the balance information or remaining balance information from the ID number identification section 4 is checked by the balance information confirmation section 10, and if there is a necessary balance, a positive determination is made, and if the balance is insufficient, a negative determination is made. and sends them to the communication control units 11° and 11', respectively. The toll calculation processing section 12 calculates the required toll or the number of tolls, and the balance notification section 14. The information is sent back to the ID plate 21.
