DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention.

1 is a configuration diagram of an illegal vehicle detection system using an RFID tag according to an embodiment of the present invention.

The illegal vehicle detection system using the RFID tag according to the present embodiment includes only a simple structure for clearly explaining the technical idea to be proposed.

Referring to FIG. 1, an illegal vehicle detection system using an RFID tag includes an RFID tag 100, a vehicle information confirmation unit 200, and a data server 300.

The detailed configuration and main operation of the illegal vehicle detection system using the RFID tag configured as above will be described below.

The RFID tag 100 is configured to be embedded in a bolt of a license plate attached to the front and rear surfaces of the vehicle.

RFID (Radio Frequency Identification) refers to a technique for exchanging data using wireless communication. Generally, it consists of an RFID reader that reads information from RFID tags and RFID tags, and RFID tags and RFID readers perform unidirectional or bidirectional wireless data communication according to communication standards. The detailed configuration of the RFID tag 100 will be described later.

The vehicle information verifying unit 200 includes an RFID reader and a video camera. The vehicle information verifying unit 200 is installed every predetermined section of the road, exchanges vehicle information with the RFID tag 100 in a wireless manner, recognizes the number of the license plate, and compares the number with the vehicle information to confirm whether or not they match.

That is, the vehicle information verifying unit 200 recognizes the number of the license plate using the image camera, and then compares the number of the license plate with the vehicle information of the RFID tag 100 installed in the bolt of the license plate. In this case, the vehicle information includes the car number, the owner information, the car number, and the fine information.

For reference, the vehicle information verifying unit 200 receives vehicle information about the car number, the owner personal information, the car number, and the fine information from the RFID tag 100. After recognizing the car number, And then transmits the changed information to the RFID tag 100 and stores the changed information in the RFID tag 100.

Since the illegal vehicle information is stored in the data server 300, the vehicle information verifying unit 200 exchanges information with the data server 300 in real time, identifies the illegal vehicle based on the vehicle information and the number of the recognized vehicle can do. In addition, the data server 300 can obtain the location of the illegal vehicle by providing the position information of the illegal vehicle to the police agency and the police officer in the field.

The data server 300 can provide the position of the illegal vehicle with the map to the portable terminal of the police officer through the wireless communication method. A portable terminal is generally referred to as a portable device such as a mobile phone, a smart phone, or a smart pad that can be used while the user is carrying it.

Meanwhile, the vehicle information verifying unit 200 may further include a speed sensing unit. The speed sensing unit may be configured to measure the speed of the vehicle through a method of emitting a laser and receiving a reflected laser.

Therefore, the speed sensing unit can grasp the position of the vehicle. That is, the speed sensing unit can confirm how far the vehicle is from the position where the speed sensing unit is installed.

The vehicle information verifying unit 200 can adjust the signal output intensity of the RFID reader by taking into consideration the current position and speed of the vehicle measured by the speed sensing unit in a comprehensive manner.

That is, if only the speed is considered, the signal output intensity of the RFID reader can be increased in proportion to the speed or proportional to the square of the speed, thereby increasing the recognition rate. That is, the signal output intensity can be increased in accordance with the speed increase.

Also, considering the current position of the vehicle, the recognition rate can be increased by increasing the signal output intensity of the RFID reader in proportion to the distance, or proportional to the square of the distance, as the position is farther away. That is, the greater the current position of the vehicle, the greater the signal output intensity.

Also, when considering the speed and the current position at the same time, it is possible to control the weight of the distance according to the speed interval after differentiating the speed interval.

For example, when the fastest first speed section is divided into a second speed section that is slower than the first speed section and a third speed section that is slower than the second speed section,

In the first speed section, the weight for the speed increase is set to 80% or more,

In the second speed section, the weight for the speed increase is given by 50 to 79%

In the third speed section, the weight of the speed increase may be set to 20 to 49%, thereby adjusting the signal output intensity of the RFID reader.

Also, the vehicle information verifying unit 200 can receive the information of the RFID tag on the front face of the vehicle and the information of the RFID tag on the rear face of the vehicle. In particular, since the RFID tag inserted into the license plate sealing screw on the rear side of the vehicle is more reliable, the vehicle information verifying unit 200 compares the information on the RFID tag on the front side of the vehicle and the information on the RFID tag on the rear side of the vehicle, It may be possible to check whether or not it is counterfeit.

For reference, in an RFID tag embedded in a bolt that fixes a license plate on the front of a vehicle, the outer surface of the head of the bolt may be coated with a reflective paint reflecting infrared rays or ultraviolet rays of a specific wavelength.

Since the reflection paint can not be identified by the human vision, the video camera of the vehicle information confirmation unit 200 can photograph the infrared ray or ultraviolet reflection paint of a specific wavelength, will be.
