It includes a header 151, a serial number 152, a vehicle registration number 153, a chassis number 154, an attachment position 155, an authentication key 156, an error check code 157, and the like.

The header 151 includes information type codes such as version information and vehicle registration number or cover information. The serial number 152 is a number for preparing a serial number or an international standard code in the integrated traffic information network, and is a code uniquely identifying a single RFID tag. Attachment position 155 means the position where the license plate is attached, and when attached to the position of the existing license plate is divided into front and rear. The authentication key 156 is for preventing privacy invasion using the digital car registration number, and the error verification code 157 is for integrity of the received data.

FIG. 2C shows an example 160 of an information format contained in an RFID tag attached to various signs installed on a road surface and around the road. These include header 161, serial number 162, cover code 163, additional information 164, execution information 165, management information 166, authentication key 167, error checking code 168, and the like. It consists of. The header 161 and the serial number 162 have the same meaning as in FIG. 2B, and the cover code 163 assigns the code values of the road surface, the caution, the regulation, and the supplementary cover provided in the related laws and the additional information 164. Provides additional information of variable length. Normally, since the read distance is short, the RFID needs to be known in advance so that it is necessary to install the RFID at a point ahead of the execution position, so that the execution information 165 is required. The management information 166 refers to information such as a location where the RFID tag is actually installed, an administrator, and the like. The authentication key 167 prohibits the collection of information by an invalid detector and the error check code 168 is provided for the integrity of the received information.

In addition, the present invention requires an information format 170 that includes a dynamic signal whose information changes over time, unlike a marker. The header 171 contains information type codes such as version information and cover information. The serial number 172 is a code for preparing a serial number or an international standard code in the integrated traffic information network and uniquely identifies a single RFID tag. The information format 170 is implemented by signal code 173 and signal information 174. For example, in the case of a traffic light, the signal code 173 includes a code representing a traffic light and a value representing a color of a signal. The execution information 175 may be the time and duration of the changed time. In addition, it is also possible to use a general guide code and the phrase 'communication delay in section A'. Next, the management information 176, the authentication key 177, and the error check code 178 are the same as in the example of the format 160 of the cover information.

2d is a conceptual diagram of RFID information processing according to the present invention. Referring to the drawings, the present invention includes an RFID tag 111 and an application system 440 included in a digital vehicle registration plate, a traffic safety sign 200, and a signal 340 of another vehicle 111. Herein, when the application system 440 issues the command a to the RFID reader 112, the application system 440 issues the command b to the RFID tag 111. As a result, when the response (c) information is sent from the RFID tag 111 to the RFID reader 112, the response (d) information is sent to the application system 440 again. In this communication process, an authentication key is used to prevent external misuse or tampering.

In addition, the RFID reader 112 writes the response information from the controller 112a into a buffer 112b limited to a predetermined amount therein. This is to prevent unspecified invasion of privacy by retaining more information than necessary. Here, as shown in the example of the information format of the information recording apparatus of the RFID reader, the buffer records the RFID code information 181 responded from the RFID tag and a time stamp 182 corresponding to the responded time.

3 is an exemplary view showing a vehicle 100 having a digital vehicle registration plate attached to the digital road traffic system according to the present invention running on a digitized road.

Referring to the drawings, the road includes a pedestrian crossing 210, bicycle pedestrian crossing 220, including the RFID tag, stop line 230, course change limit line 240, pedestrian crossing notice 250, center line 260, lane line Traffic signs such as road signs 200, caution signs 310, indication signs 320, regulatory signs or auxiliary signs 330, signal signs 340 including RFID tags, detectors including RFID readers, etc. (350) is shown.

Figure 4 shows an example of an application service using a two-way digital license plate that can be provided according to the present invention. Referring to the drawings, the vehicle registration 510, road management 520, facility management 530, traffic police 540, taxation 550, emergency rescue using the two-way digital license plate in accordance with the present invention ), Automobile driving 570, traffic information 580, insurance 590, additional application 600, and the like. These services are achieved through sharing information authorized for each service using the information filter 410 around the integrated traffic information network 400, respectively.

The vehicle registration 510 is used for the information of the digital vehicle registration plate according to the present invention in the case of new registration of a vehicle, designation of a vehicle registration number, grant and seal of a vehicle registration plate, change registration and transfer, export, junk car, and erase registration. Use a detector to read and manage changes. Based on this, the unregistered vehicle can be prevented from running on the road.

The road management 520 is attached to the RFID tag containing the information as shown in Figure 2c when the installation and change as a management for the facilities or signs associated with the road and the identifier, installation location, installation date, manager for them Information such as database is managed. This information can be classified into a static information format 160 that can be installed and read only once and a dynamic information format that can be changed 170. In all cases, the authentication key should be applied to prevent forgery.

The RFID tag which is interlocked with a device whose signal is dynamically changed may be configured as shown in FIG. 5 such that the information of the tags 200 and 300 is changed only by the signal device 340 without being forged by an external signal. In this case, a method of changing the information in the RFID tag by controlling the signal device using an internal circuit is used, and the method of reading and processing the information in the RFID tag is the same as in the RFID information processing conceptual diagram of FIG. 2D. . In this case, information such as a traffic light of a crossroad, a variable lane, a curfew and a restriction, a traffic classification, and the like may be displayed on the display window 341 of the information terminal 135 in the vehicle through the dynamic information format 170 of FIG. 2C.

The facility management 530 attaches an RFID tag to a building or a facility managed by a local government and provides a service as in the road management 520. For example, city road names and building addresses can be easily identified using RFID tags in a car or a portable device. In connection with the geographic information service, it is also possible to provide a service for easily finding a route to a destination.

The traffic police service 540 is a service to control the violation of the law using a digital car registration number and the RFID tag attached to the road and facilities. Various services can be applied to this, but the present invention provides an embodiment of providing a driving record of an accident, speeding violations, and identifying a parking violation. In addition, when linked with vehicle inspection information, taxation information, insurance information, wanted and stolen information database, insurance (590) services such as violation of regulations, tax-free vehicle identification, and insurance (590) services such as uninsured vehicle identification are also available at low cost. It can be provided easily.

The most changed service according to the present invention is that it provides driving records at the time of the accident. In a typical accident, victims often lose their ability to testify, and in some cases accident investigations may be conducted in a way that favors those who can testify. Therefore, victims are eager to find witnesses, but most witnesses do not take account of the violations of their personal lives. In addition, in the case of speed estimation at the time of the accident, the tire marks left when the brake of the accident vehicle is braked, but if the brake operation is not intentional, there may be a case in which the official investigation is different from the actual results.

In the present invention, as shown in FIGS. 2A to 2D and 3, the vehicle registration plate provides a driving record including the registration number of the adjacent vehicle and information of surrounding signs and facilities, so that the collision vehicle can be found using the accident time information. In addition, estimates of the speed at the time of an accident can be made from the time at which the surrounding signs and information of the facility were read and the location information between the signs and the facility. If the RFID reader 112 is read in the front and rear order of the license plate, it can also know the direction of travel of the vehicle. In addition, by installing a detector in an accident-prone area such as an intersection and a curved road, a vehicle for an accident can be tracked based on the driving record of the license plate when an accident occurs. Based on such data, it provides a fundamental means to prevent accident investigation and hit-and-run accidents that are more true.

6 is a view illustrating a speed violation control according to the present invention. Referring to the drawing, the speeding violations are penalized step by step depending on how much the speed limit v _r is exceeded (δ ₁ , δ ₂ ) around a specific point by the fixed and mobile cameras. In the present invention, as shown in FIG. 6, when the detector a and the detector b are installed at a distance d interval for a specific vehicle 100, if the time of reading information from the two detectors is t _a and t _b , respectively, The speed is v = d / (t _{b -} t _a ) We know that again v> v _{r +} δ ₁ v> v _{r +} δ ₂ Penalties may be imposed by classifying This provides the advantage that the use of expensive electronic equipment, such as cameras and Doppler devices, and the restrictions on point cracking can be replaced by low-cost electronic equipment, and improved by the effect of section control.

That is, the present invention is a method for detecting a speed violation using a detector a and a detector b installed on the road at a distance d interval for a vehicle equipped with an RFID tag, and measuring the time of the vehicle passing through the detector a and the detector b. Doing; Calculating an average speed by dividing the time difference measured by the detector b and the time difference t _{b -} t _a measured by the detector a by the distance d; And imposing a penalty by adding the excess speeds δ ₁ and δ ₂ to the average speed detected in the above-described speed limit v _r .

7 is an exemplary diagram for monitoring a parking violation according to the present invention. Referring to the drawings, the present invention can provide a service more realistically in the case of parking violations. The parking lot monitoring detectors 351 and 352 according to the present invention collect information of the vehicle 100 in the monitoring area by using a directional antenna and transmit the information to the traffic control server 430 through wired or wireless communication means 400 and 420. Send. If the server information continues for a predetermined time or more, the server 430 considers the parking stop violation and warns the owner of the vehicle owner's mobile terminal 440, which is retrieved from the vehicle registration database, of the violation by the text information service.

That is, the present invention is a method for monitoring the violation of the vehicle equipped with the RFID tag by using two parking stop monitoring detectors installed in the parking stop violation zone, the vehicle information in the monitoring zone by using the parking stop monitoring detector Collecting; Transmitting the information collected in the step to a traffic control server through a wired or wireless communication means; And if the vehicle information continues to exist for more than a predetermined time in the traffic control server, deemed to be a violation of the parking stop, and alerting the vehicle owner's mobile terminal retrieved from the vehicle registration database of the violation with the text information service. do.

Violation vehicles monitored by the method described above provide the towing team with towing missions as textual information after the allowable time. The tow team reads the registration number of the tow vehicle and transmits the tow garage and time information to the server before carrying out the mission. The server again informs the car owner of this fact via text service. Owners who do not check the text information service can check the location of their car through the Internet to find out the fact that the car is located and pay the fine and collect it.

8 is a conceptual diagram of an emergency rescue according to the present invention. Referring to the drawings, the emergency rescue 560 service of the present invention is a service to prevent subsequent accidents by extinguishing fires, emergency measures and evacuation of casualties, and removal of neglected vehicles in the event of an accident. First, when pressing the emergency rescue button on the information terminal equipped with the communication function in the accident vehicle (101, 102), the car registration number, the recently read sign information, or facility information according to the outbreak data through the wired and wireless communication network (400, 420) The server 430 is stored. This is notified to the emergency response team 134 again, and the response personnel identify the accident site based on the received information, and promptly dispatch firefighting (131), medical (132), and rescue (133) teams for relief and rescue. This becomes possible.

In addition, if there are a lot of people around the accident can be promptly handled by a third party's report, but in the case of missing persons in a rare place, the effective time has passed since the accident may not be able to rescue the casualty. When missing vehicles occur in dangerous areas, the missing points can be quickly estimated and searched by tracing the passing points of the missing vehicles through information collected through detectors 351 and 352 installed at predetermined intervals on the roadside.

The vehicle driving service 570 provides information to help the vehicle driving through the information terminal installed in the vehicle by using information collected through a license plate or a separate RFID reader according to the present invention. Examples of such services include alerts, cautions, and notification services. The warning service occurs when the main law is violated, for example, when the speed limit is exceeded by the method shown in FIG. 6.

Attention service is to notify in advance of dangerous areas such as fog, rockfall, cliff, accident area, construction area, etc. It is very important to inform in advance if you are in a dangerous area, such as a curved road or railroad crossing. In addition, by analyzing the numbers of adjacent vehicles, warning messages are provided for emergency vehicles, emergency rescue vehicles, child protection vehicles, and large vehicles so that drivers can take actions such as yielding lanes or reducing their speed.

9 shows the concept of a digital road reflector using RFID. Referring to the drawings, the present invention can be installed and operated in parallel with the existing visible road reflector in a place where the field of view is limited, such as a curved road or railroad crossing, using a digital road reflector using an RFID tag and a reader. The ascending vehicle 101 on the curved road cannot see the left vehicle 102 due to the obstacle 360. In this case, the detectors 351 and 351a and 353 and 353a may recognize the adjacent cars 101 and 102, respectively. In addition, the direction of travel can be known by the detection order of the license plate of the front and rear.

Such information is exchanged for detection periods through short-range wired / wireless communication means, and the detectors 351 and 353 record the obtained information on the chips of the interconnected RFID tags. Then, as shown in the information processing conceptual diagram of the dynamic signal device of FIG. 5, the changed information of the RFID is read from the driving vehicle so that the information terminal knows that the vehicle is approaching the opposite side of the curved road.

In addition, such services can be provided for pedestrians with a portable device having a pedestrian classification code. In addition, when the train approaches the railroad crossing, if the access information is recorded on the chip of the adjacent RFID tag of the driving vehicle in a similar manner as above, the vehicle can be identified and the breaker can be controlled through the automation control device.

The notification service means providing general information. Here, the main point, the milestone and the traffic safety sign information by the read-only RFID tag information 160 of FIG. 2C may be informed. In addition, the read-write RFID tag information 170 of FIG. 2C may be used to provide information such as an average speed of a running road, a scheduled arrival time of a main destination, and a congestion section. This is also expected to replace large text information providing facilities on the road.

Meanwhile, in the case of pedestrians, if the RFID tag having the same pedestrian code is attached to the portable device instead of the vehicle registration number in FIG. 2B to prevent privacy infringement, the pedestrian may also provide a service for notifying the driver that the pedestrian exists. In addition, attaching an RFID reader to a portable device may benefit from similar services provided in a vehicle.

The traffic information 580 service is a service that informs the driving speed of each time zone, the congestion area, and the accident area by synthesizing the traffic information of each vehicle. Finally, the service is statistically processed by the back office to calculate information for the car driving service 570 provided to the user.

The additional application 600 service is a service that can be additionally provided by a program in the information terminal according to the present invention. For example, automatic identification of automobiles enables automatic charging according to authentication and service in access to parking lots, gas stations, car washes, repair shops, buildings, and institutions. It is also possible to make automatic payments in connection with financial institutions. Notifications for other restaurants, entertainment, relaxation facilities, and events are also available.

As described above, the present invention attaches RFID tags to two-way digital license plates, traffic safety signs, signals, buildings, and facilities, and collects basic information on road traffic using related electronic devices and integrated traffic information networks. Services such as car registration, road management, facility management, traffic police, taxation, emergency rescue, car operation, traffic information, supplementary services, insurance, etc. can be provided through processing, dissemination, and synthesis.

According to the disclosed subject matter, it is possible to reduce illegal cars and traffic violation vehicles on the road, provide a safer and more convenient traffic environment for the driver, and present public evidence to identify the cause, especially in the event of an accident. For example, it can provide the relevant institutions with a foundation to handle their tasks more efficiently and at a lower cost, and ultimately provide a means to advance the existing physical and electronic transportation environment to the ubiquitous level wherever and whenever it exists. have.
