Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle traffic control device that is used, for example, in a monthly parking lot and is capable of regulating the number of people such as automobiles.

[Conventional technology]

Conventionally, this Yuzu traffic control includes, for example, regulating the number of people in parking lots. Under this regulation, the date, time, etc. are printed on the card at the time of entry, and the card is given to the user to allow the car to enter. When exiting the bath, the manager etc. collects a fee commensurate with the parking time. Many methods are used, such as regulating parking lots and using magnetic card devices to manage parking lots.

[Problem that the invention seeks to solve]

However, in the above-mentioned vehicle traffic control, the license plate number of the vehicle entering the parking lot is not checked, so it may not be possible to tell if a vehicle other than the one on the contract is entering the parking lot, or if the vehicle uses an old magnetic card device. In some cases, there is a risk that the magnetic card may be counterfeited, and furthermore, there are concerns that the recorded information may be lost or altered due to proximity to ferromagnetic material.

This invention was made in order to solve the problems of drivers, and aims to provide a vehicle traffic control device that can perform reliable traffic control and that does not cause the recorded contents of the card to be lost or changed even in strong magnetic fields. purpose.

[Means to solve all problems]

The vehicle traffic control device according to the present invention records the vehicle number (gray) in advance in the data memory of an IC card, and reads the recorded number and number 9-Great League. The IC card compares and verifies the license plate number of the vehicle and outputs the judgment R1.Based on this output result, the gate device that opens and closes the entrance and exit of the vehicle passageway is controlled.

[For production]

In this invention, when a vehicle approaches an entrance/exit, its license plate number is read, and the license plate number recorded on the IC card and the number read by the license plate reader are read using the IC card brought by the owner. The license plate number is compared with the license plate number, and the judgment result is output. If the judgment result is normal, the gate is opened, and if the judgment result is abnormal, the gate is kept closed.

〔Example〕

FIG. 1 is a diagram showing the configuration of a vehicle traffic control device according to an embodiment of the present invention. In the figure, ] &:j: 2 by car

An IC card with a pre-recorded number 0, 4 is this IC
A card terminal device 5 performs input/output interface between the card 3 and the outside, and a TV left camera 6 is used to capture images at 9-7° rate 2. - This is a lighting device that provides sufficient illumination for route 2. 7 receives the output from the TV left camera, processes the image of the license plate 2, transmits the data to the card terminal 4, and also sends the data to the card terminal 4.

FIG. 2 is a diagram showing the configuration of the IC card 3.

10 is a microcomputer having arithmetic functions and an input/output function with the card terminal 4; 11 is a data storage semiconductor memory for recording data to be input/output to/from the card terminal 4;

For example, ROM), 13 is a semiconductor memory (for example, RAM) in which the microcomputer 10 temporarily records data sent from the outside or data to be sent to the outside.
It is.

Next, the operation of the vehicle traffic control device configured as described above will be explained. When the automatic distortion 1 approaches a parking lot entrance or a river mouth cage device 8, which is an entrance/exit of a traffic road,
The position 9 fully detects the entrance of the car, and uses the TV left camera and the lighting device 6 to take in the image of the license plate 2 to the processing device 7.

The processing device 7 extracts and recognizes the number of the license plate 2 from the image data, and transmits the recognized information to the card terminal 4.

On the other hand, the original user inserts the IC card 3 he/she brought into the card terminal 4 and waits until the r-tower 8 is opened.

The IC card 3 contains the number of the license plate 2 (for example,
59, 1234, etc.) are recorded in the data memory 11, and there, the IC card 3 receives the signal of the number grade 2 sent from the processing device 7, and temporarily stores it in the RAM of the semiconductor memory 13 (for example, the memory address A), the contents of the RAM (A) and the already recorded contents of the data memory 11 (for example, memory address B) are compared and verified to determine pass/fail, and the results are output. The processing device 7 receives the output result, and if the information output from the IC card 3 is normal (when the contents of the RAM (A) and data memory (B) match), the processing device 7 opens the gate 8 and starts the car I.
The abnormality (RAM (A) and data memory (B)
) If there is a discrepancy in the contents of the parking lot, please do not open r-t8 and report this to the parking lot operator, or check the entrance time, bathing time, parking fee, etc. The data may be recorded in the data memory 11 of the card 3.

〔Effect of the invention〕

As described above, according to the vehicle traffic control device of the present invention,
In addition to reading the license plate number of the vehicle with a license plate reader, the recorded license plate number is compared with the output of the Number Great League using an IC card on which the vehicle's license plate No. A is recorded in advance, and based on the results. Since the system is configured to perform vehicle traffic control based on the above, the following effects can be obtained.

(1) Since an IC card is used, it is possible to prevent secrecy and counterfeiting, which was difficult with magnetic cards.

(2) Since the license plate number recorded on the IC card is compared and verified with the number read by the license plate reader, the passage of vehicles other than those under contract can be completely prevented.

(3) Personal information can be recorded in the data memory of the V-branch IC card, so there is no chance of data being lost or changed due to a strong magnetic field.

(4) By combining with a gate device, etc., traffic control can be performed automatically, so management labor can be saved in the case of parking lots, etc.
