Abstract

PROBLEM TO BE SOLVED: To eliminate the disadvantage that a traveling direction such as reverse traveling cannot be known only by the visual data displayed on license plates 2 and 3, that a car body 1 loses its ownership when the number plates are separated therefrom and the car owner suffers a property loss, and that the license plates 2 and 3 may be subjected to theft, forgery or alteration, and misused for terrorist attacks, abduction, reckless driving or the like.SOLUTION: Visual data such as a seal, a logo sequence or a serial number displayed on a license plates 2 and 3 are simultaneously compared and collated based on the electronic data of an on-vehicle device to find a reverse-traveling vehicle or an unmatched vehicle, and in order to guarantee driver's safety and the ownership of a car body 1, a vehicle registration number to be presented is searched for and arranged to invalidate such an action as theft, forgery or alteration of the electronic license plates 2 and 3, thereby suppressing misuse for terrorist attacks, abduction, reckless driving or the like.SELECTED DRAWING: Figure 1

Description

  The present invention relates to invalidation of the act of theft, forgery, and alteration related to a license plate.

  In addition to the threat of terrorist attacks on important facilities, the number of license plate theft exceeds 20,000 every year, and with the advent of 3D printers, elaborate counterfeit license plates and pistols are made and used for planned crimes such as kidnapping and runaway It is broken. On the other hand, 242 reverse runs on the highway occurred in the last year, and 12% of the cases were “dementia”. In order to prevent terrorism and kill dead traffic accidents and crimes, unmanned speed violations, etc. In order to promote investigations of crackdown devices and traffic incidents, various issues and solutions related to license plates are being discussed.

  Automobile registration number signs, etc. that have been declared theft damage can be found immediately when searching the N system from a serial number, etc. while driving, but a counterfeit license plate that has no actual damage or damage has not been found. Hmm. Of course, the reverse run cannot be recognized from the license plate, and it is not understood by the running party. Therefore, there is a need for a device that can automatically control unmanned traffic violations and investigate crimes in a wide area.

  Since the serial number of the car registration number mark changes for each vehicle, a method of punching letters and numbers on thin steel plates and tightening them to the car body with bolts is used, but this thinness obstructs visual inspection and reading with the N system A copy is made for the purpose, and it is abused by making it difficult to see it by altering or overlapping or folding letters and numbers.

  In Patent No. 5342275, when a pedestrian encounters or witnesses a sneak or a crime, he / she reports on the letters and numbers of the license plate, but there are many digits, and the credibility of the sighting memory is questioned. However, the technology that supports this by recognizing images and the combination of easy-to-remember animal and plant logos and numbers such as flowers and fruits of the local number has been described, but it has not yet led to a radical solution to counterfeiting.

  When the license plate is fixed to the vehicle body with bolts as in the technology of Japanese Patent Application Laid-Open No. 2010-133547, the heads of the bolts inevitably have protrusions that can be easily removed using a tool and are forged. It is a cause.

  As disclosed in Japanese Patent Application Laid-Open No. 2003-34197, there is a mechanism to provide a limit switch at the lower part of the number plate fixing screw to emit a signal when the number plate is replaced. But there is no effect at all. Also, even if the license plate is counterfeited by visual inspection or a camera, if it is covered with a counterfeit license plate on a genuine license plate, it will be difficult to understand and a hole will be made in the sealed part to hide the seal. Even if a security switch is applied to the genuine number plate, there is no effect.

  Japanese Patent Laid-Open No. 2002-260164 discloses a method for reading a harmonic wave by emitting an excitation electromagnetic wave from a road-side RF-ID antenna, exciting a radio signal of an IC tag embedded in a license plate with a fundamental wave, and reading a plate mark. There is a method to transmit information to a mobile terminal, but because the electric field strength in the space is strong and the communication range is wide, a vehicle that is misidentified as a non-mounted vehicle or is traveling in an oncoming lane on a road where IC-tagged vehicles and non-mounted vehicles are mixed Communicating with the license plate IC tag, there is a difference in positioning and direction judgment, and if it is carried away in the form of being combined with the license plate, it is put into practical use because it increases the risk of being misused by being mounted on another car. Absent.

  In Japanese Patent No. 3979179, when a reflection regression infrared sensor provided at the four corners of a vehicle detects a road marking of a control point having a recursive reflection function, a radio wave loaded with a radio code is transmitted from a transmitter mounted on the vehicle. A vehicle recognition device is described that detects a vehicle lane change, forward / reverse, forward / reverse direction and attitude according to the reception order. With charged waves, video transmission is delayed and a code-encoded electronic number is required.

  Furthermore, in Japanese Patent Application No. 2014-144139, an automatic driving control unit having a function of a GPS / vehicle communication terminal is mounted on the own vehicle, and the GPS / vehicle communication terminal of the preceding vehicle in the same lane has a radius of the same communication area. When entering the range of about 100m, information such as lane classification, position coordinates, vehicle speed and road friction coefficient is automatically exchanged by inter-vehicle communication, displayed on each other's in-vehicle display, and the distance between the antennas from the data is the stop distance + number If the vehicle reaches m, there is an automatic driving mechanism that controls the accelerator and brakes with the automatic driving control unit and keeps the stop distance + several meters in the lane, but whether the license plate displayed by pedestrians is authentic or not I do n’t know.

Issued by the Ministry of Land, Infrastructure, Transport and Tourism

  The problem to be solved is that the base of use, classification number, application, and serial number marked on the license plate are merely recording media and are not data that can directly identify the owner. The vehicle and the license plate are combined to require an authentication function, and the seal is the only important sign that connects them, but it is attached only to the rear license plate and is a small cylindrical simple structure. There is a drawback in that it can be avoided from being visually recognized or recognized by the N system in a state where the seal portion of the counterfeit license plate is rounded and the head is placed on the genuine license plate.

  As mentioned above, a lot of information is exchanged by inter-vehicle / road-to-vehicle communication, such as ETC and taxi radio. However, when specifying a vehicle, the description is consistent between the vehicle body and the license plate, or there is an error in the direction of travel. There is a need to synchronize and recognize at one point. While there are vehicles with no IC tag / ETC on-board unit, there is no seal and no legal binding force within a relatively wide communication range with low power. It is used for planned crimes such as kidnapping and runaway by misusing counterfeit license plates from the place where vehicle identification, positioning and direction determination are performed only using the visual information of the front license plate that is not, and the conventional unmanned speed There has been even a refund of fines to traffic violators who have been cleared by automatic control devices for violations. On the other hand, on the highway, the reverse running with high risk of a frontal collision is repeated every day without knowing even by the elderly and people with dementia.

  Because the counterfeiting factor is the thinness of the plate, the front and rear license plates 2 and 3 are easy to transmit electromagnetic waves, are light and strong, and prevent desorption, stacking and bending, and letters and numbers on 3D printers, etc. Synthetic resins suitable for the individual processing of embossing are preferred.

  The fixing holes of the front and rear license plates 2 and 3 to be fixed to the vehicle body 1 are processed as shown in FIG. 6 and fixed with a countersunk screw 4, and the upper part is covered with a drop cover 5 having the same diameter as the countersunk screw 4. Fix it so that it is flush with the surface.

  A 3D hologram seal 6 that is difficult to counterfeit or a logo mark 7 that is likely to remain in memory is affixed to the upper surface of the drop lid 5. The logo mark 7 is on the left side of the front license plate 2, and the 3D hologram is on the right side. The rear license plate 3 has a 3D hologram seal 6 on the left side and a logo mark 7 on the right side.

  On the back of the front and rear license plates 2 and 3, there is a holder 8 for storing the RF-ID card or tag, and a special card or tag that is issued by the Land Transportation Bureau to be fixed at the correct position, and is different depending on the vehicle and front and rear. The ID medium 9 is housed and sealed on the surface with a sealing paper 10 made of a non-metallic material that easily transmits electromagnetic waves.

  On the other hand, the vehicle body 1 is provided with an ID reading RF-ID reader 11 of an ID medium 9 from the inside of the vehicle by using a material such as a bumper portion facing the holder 8 accommodated on the back of the number plates 2 and 3 that allows easy transmission of electromagnetic waves. The signal is fixed and read into the vehicle-mounted device 12.

  The ID of the imported ID medium 9 is different between the front and rear license plates 2 and 3, and the AND of the front and rear ID media 9 is taken out of the setup of the vehicle-mounted device 12, as a start button 13 such as a cell motor. Always monitor the removal of the front and rear license plates 2 and 3.

  For the setup, for each sensor / transmitter 14 at the four corners, when the road marking 16 is read, it is superimposed on the radio code emitted from the sensor / transmitter 14, and the 3D hologram seal 6 is different between the front and rear license plates 2, 3. And the data of the logo mark 7 are input from the LAN cable 15 connected to the vehicle-mounted device.

  There is already a vehicle recognition device of Japanese Patent No. 3979179 that identifies the vehicle body 1 and determines the direction and posture when the four corner sensors of the vehicle detect the road marking 16 of the control point. The image data produced based on the visual information of license plates with different numbers are wirelessly encoded and added as the same information for each sensor / transmitter 14 at the four corners.

  The relationship between the electric field intensity of the radio wave emitted from each sensor / transmitting unit 14 and the radio wave received by the roadside antenna 17 can be obtained by the following formula 1, but it is considered that about 500 μV / m is good in the 3 m measurement method and is transmitted with the electric field intensity. It is preferable to use FM waves in which stations are switched automatically.

  The license plates 2 and 3 are made of synthetic resin, etc., and are lightweight, strong and easy to transmit radio waves, and can be easily attached / detached / stacked / folded with a single screwdriver. It is necessary to peel off the 3D hologram seal 6 and the logo mark 7 that are extremely difficult to use, remove the drop lid 5 at two locations, and remove the two countersunk screws 4.

  In the unlikely event that the license plates 2 and 3 are removed successfully, the data to be enclosed is only the ID of the different on-vehicle device even if it is mounted on another car, and the letters and serial numbers on the surface are altered or changed. However, the external vehicle-mounted device 12 is not recognized, the cell motor start button 13 or the like does not function, and the counterfeit of the license plates 2 and 3 is exposed at the installation position of the N system camera 18 in return.

  To the fixed part of the front license plate 2, the left side is a logo mark 7, the right side is a 3D hologram seal 6, and the rear number plate 3 is directed to the left side with a 3D hologram seal 6 and the right side is a logo mark 7. From the recognition of logo mark 7, we can see the abuse of the ETC handicapped person discount use system by the healthy people and the occupation of the parking space for the disabled, and from the history of the reported time that we have recognized even if we encounter a habit or crime damage, There is an advantage that the suspect can be traced only with the last number of the serial number, and by cooperating with Japanese Patent No. 3979179, more reliable positioning / direction determination is possible.

  Even if the ID medium 9 is removed from the back holders 8 of the front and rear license plates 2 and 3 and stored in the outer license plates 2 and 3 and mounted on the original body 1 again to steal the car, the N system camera 18 Is different from the electronic data of the vehicle-mounted device 12 and is recognized as a stolen vehicle.

  The RF-ID reader 11 of the vehicle body 1 takes measures such that the engine does not start with the ID medium 9 of the front and rear license plates 2 and 3 and the ID medium 9 on one side alone.

  In addition, by adding the output of the card reader 20 or the alcohol detector 21 of the electronic driver's license 19, the engine 1 and the front / rear license plates 2, 3 and further the driver's license 19 etc. are not set properly. It is possible to construct a system that does not start.

  By adding the electronic data of the vehicle-mounted device 12 and the visual data of the license plate as the same two-line data to the Japanese Patent No. 3979179, the sensors / transmitters 14 at the four corners of the vehicle superimpose the radio codes emitted when the road marking 16 is read. In addition to the series of registration numbers common to the front and rear license plates 2 and 3, in addition to the front and rear of the corresponding N system, an electronic signal in which the positions of the 3D hologram seal 6 and the logo mark 7 that are different in front and rear are input The license recognition device 24 for the license plates 2 and 3 is activated.

  The road markings 16 at the control point of the N system camera 18 are read by the sensors / transmitters 14 at the four corners of the vehicle, and the electronic data of the vehicle-mounted device 12 and the visual data of the front and rear license plates are compared and contrasted at the control point on the N system camera 18 side. The vehicle body 1 can be specified by the positioning, and the positioning and the reverse running direction can be determined.

  The electric field intensity of the radio wave received by the roadside antenna 17 receiving the radio wave emitted from each sensor / transmitting unit 14 is the strongest directly under the sensor / transmitting unit 14 where the receiving antenna is closest, and the intermediate point with the other end is the weakest. When the edge becomes the strongest, it is already the weakest by removing from the communication range 22, and by setting it to about 500μV / m with the 3m measurement method, it will not interfere with other communication devices and the entire road surface will be covered with snow, etc. Even if recursive reflection occurs, the FM station is used to automatically switch the transmitting station depending on the electric field strength, for example, from left front to left rear.

FIG. 3 is a front perspective view showing a method of implementing the electronic license plate. FIG. 4 is an explanatory view showing the surface of the electronic license plate. FIG. 5 is an explanatory view showing the back surface of the electronic license plate. FIG. 6 is a cross-sectional explanatory view showing a method of implementing the electronic license plate fixing portion. FIG. 7 is an explanatory view showing a method of fixing the electronic license plate to the vehicle body.

  The front and rear license plates 2 and 3 are changed to materials that allow easy transmission of electromagnetic waves. Thickness is added to reinforce the fixed part, making it difficult to remove, bend, overlap, and reuse. Monitoring the removal of the embedded ID medium 9 from the vehicle-mounted device 12 on the vehicle body 1 side, cooperating with other security switches, and if any of the front and rear license plates 2 and 3 are missing, an alarm is issued and if necessary Take measures to prevent departure.

  Furthermore, the electronic data in the vehicle-mounted device 12 and the letters / numbers / logo marks, etc., marked on the front / rear license plates 2 and 3 are used as visual data, and the road marking 16 of the control point 23 is used as two different kinds of data common to both. Synchronize with the electronic data in the vehicle-mounted device 12 at the time of detection by the sensor / transmitting unit 14 at the four corners of the vehicle, and compare and contrast the visual data acquired by the N system camera 18 at the same place. Minimize the purpose such as separating 1 and criminal acts such as counterfeiting and alteration and reverse running before the situation occurs, and managing the entry / exit of the escape / reverse vehicle and entry / exit of the vehicle with one point of single route The number of parts was realized without impairing the appearance.

  FIG. 6 is a cross-sectional view of an embodiment of the electronic license plates 2 and 3 of the present invention, which is fixed to the vehicle body 1 with a countersunk screw 4 and the upper part is covered with a drop lid 5 having the same diameter as the head of the countersunk screw 4. Fix it so that it is flush with the surfaces of the plates 2 and 3.

  The 3D hologram seal 6 or the logo mark 7 is affixed to the front and rear license plates 2 and 3 by changing the arrangement as shown in FIG.

  Even if the ID medium is removed from the back of the license plates 2 and 3 and replaced with an external license plate, the electronic data of the vehicle-mounted device and the visual data of the license plate are different in the N system so that they are recognized as stolen vehicles. .

  FIG. 1 is a control system diagram in which an electronic license plate according to the present invention is mounted on a vehicle body 1. Since the subject of the present invention is a method of mounting an optical system sensor, a road-to-vehicle communication terminal, etc. Description of is omitted.

  As shown in FIG. 2, when searching for the electronic license plate 3 on the rear surface of the vehicle body 1 from behind, the N system is recognized by signals when the sensors of the right front sensor / transmitter 14 and the left rear sensor / transmitter 14 read the road markings. When the device 24 is activated and the front of the vehicle body 1 is searched from the front as shown in FIG. 3, the left front sensor / transmitter 14 and the right rear sensor / transmitter 14 read the road marking 16 as a signal when reading the N system camera. 18 recognition devices 24 are activated.

  In the case of searching from behind with the above detection, the image can be recognized as forward running when the N system is activated by the signal of the left rear sensor / transmitting unit 14, and reverse running when activated by the right front sensor / transmitting unit 14, and conversely When searching from the front, the direction is determined as reverse running when the N system camera recognition device 24 is activated by the electronic signal of the right rear sensor / transmitting unit 14 and when it is activated by the left front sensor / transmitting unit 14.

  Also in this case, in cooperation with the technology of Japanese Patent No. 3979179, the image recognition, the arrangement of the 3D hologram seal 6, and the positioning / direction determination based on the operation order of the four corner sensors of the vehicle are double-checked and can be accurately recognized.

  The N system recognition device 24 is activated by a signal such as a vehicle registration number superimposed on the radio code when the road marking 16 is read for each sensor / transmitting unit 14, and the license plate 2 The position of the vehicle body 1 detected by detecting the electronic data 3 and the road marking 16 and matching the position of the vehicle body 1 recognized by the N system camera 18 and comparing and comparing the contents, the position of the forged license plate and the position of the vehicle body 1 are identified and operated. And direction determination such as reverse running can be performed at the same time.

  Guaranteeing the authenticity of license plates 2 and 3, deterring planned crimes such as threats of terrorism, kidnapping and runaway, preventing reverse running and accidental start-ups, and violating unmanned traffic in order to eliminate fatal traffic accidents and crimes The system can be used not only for automatic control devices and systems that promote wide-area crime investigations, but also for various driving support and welfare services, including automatic settlement of parking and tolls according to time and distance.
