Referring to Figure 1, the prior art will be described.

First, a vehicle information reading apparatus for extracting vehicle information-at least license plate information-by image processing from a vehicle photographed by a camera will be described.

Generally, a plurality of field control units (about 10 units) 30 are connected by the communication network 100 to be integrated and operated in the operation control unit 50. The field control unit 30 may include a camera unit 10, 10a which actually photographs a predetermined image including a vehicle, and a controller 20, 20a connected to the camera unit 10, 10a. In general, the field control unit 30 extracts the license plate by image processing the photographed image, and photographs the extracted license plate information (for example, "000,000 0000") into a computer-readable form (for example, text). In addition to the video, it transmits to the operation control unit 50.

Meanwhile, the communication network 100 used in the vehicle information reading apparatus is a communication network having a relatively low security level. Representatively, it is the Internet network, and this communication network is actually a collection of many networks, and is an open communication network (hereinafter referred to as "open communication network" for convenience) by anyone using the Internet protocol, and this network is a lease provided by a network leasing company. It is a net. The field control unit 30 and the operation control unit 50 performs bidirectional communication using the open communication network 100. That is, the field control unit 30 transmits an image captured using the open communication network 100 to the operation control unit 50, and also receives various control signals from the operation control unit 50.

Next, a communication network 200 in which a relatively high security level or extremely security is required will be described. Such a communication network is representatively a communication network used by a national agency (hereinafter referred to as "closed communication network" for convenience). An example of such a communication network is a kind of internal network operated by the National Police Agency, etc., which is an intranet. The internal network includes various databases 255, for example, a database on which criminal investigation-related information is recorded, an arrangement vehicle database, and such a database. A server 250 for processing 255 (hereinafter referred to as " troller information device " for convenience) is connected. However, such a communication network 200 is an intranet and can be connected to the client computers 220 and 220a only within the corresponding network.

On the other hand, as described above, in order to arrest a vehicle for a crime, vehicle information read by the vehicle information reading apparatus, such as license plate information of the vehicle, the current passing position, the passing time of a specific place, etc. Preferably delivered. However, due to hacking concerns, an open communication network to which a vehicle information reading device is connected and a closed communication network having a vehicle database cannot be interconnected.

Therefore, in the related art, the vehicle information transmitted to the operation control unit 50 through the open communication network cannot be transmitted and received by communication to the arrangement vehicle information device 250 connected to the closed communication network, but the vehicle information in the vehicle information reading device. To manually input the query to the wanted vehicle information device 250 connected to the closed communication network 200, or back up the wanted information of the wanted vehicle database 255 to the US, CD, etc. to operate the vehicle information reading device. There was no method other than the operation by inputting to the control unit 50 or the like. And even in the latter case, the problem of hacking exists.

Therefore, in the above-described prior art, there is a problem that it is practically impossible to obtain the appearance information of the wanted vehicle in real time by comparing the vehicle information collected by the vehicle information reading apparatus with the data recorded in the wanted vehicle information apparatus inside the police station.

The present invention is to solve the above problems, an object of the present invention is to prevent the hacking vehicle information reading apparatus and method that can pass the necessary information from the open communication network to the closed communication network, hacking prevention vehicle information transmission device and method and It is to provide a system using this.

Secondly, due to the security level of the network or a physical security breach, it is possible to achieve different operational effects such as integrating the respective communication networks by interworking different communication networks that are difficult to integrate.

Referring to the accompanying drawings, it will be described a preferred embodiment of the present invention.

First, referring to Figures 2 and 3, a preferred embodiment of the anti-hacking vehicle information transmitting apparatus according to the present invention.

Anti-hacking vehicle information transmission device 300 receives the output data ("image" for convenience) output in the form of an image from the vehicle information reading device that can be connected to the open communication network (S1), the image processing the received output data again It can be converted into data identifiable by a computer (S3), and can be connected to an open communication network through a predetermined interface. The data (vehicle information) which can be identified by the computer through the image processing again can be stored in a predetermined storage device (S3).

That is, in the present invention, the image output from the open communication network (100 of FIG. 1) in the anti-hacking vehicle information transmission device 300 is simply transferred without a connection between the communication networks-a kind of data capture-and then imaged again It can be recognized as processing and delivered to the closed network (200 in FIG. 1), so there is no fear of hacking.

It will be described in detail as follows.

The data acquisition unit 320 for obtaining output data output from the vehicle information reading apparatus connectable to the open communication network is connected to a control unit 310 for extracting vehicle information from the output data. In addition, the controller 310 is connected to the interface unit 340 for communicating with the closed communication network. In addition, the control unit 310 preferably includes an information storage unit 350 for storing the vehicle information. Of course, the controller 310 is preferably connected to the input unit 322, such as a keyboard, the output unit 330, such as a monitor, a printer. On the other hand, reference numeral 58 which is not described in the operation control unit 50 of the vehicle information reading device is a printer, 54 is an input unit 54 such as a keyboard, 59 is an interface unit for communicating with an open communication network, 56 is a monitor , 52 is a control unit of the operation control unit 50.

Each component will be described in detail as follows.

The data acquisition unit 320 receives the image output from the operation control unit 50 of the vehicle information reading apparatus, that is, the image data output to the monitor 56 as it is. Accordingly, the vehicle information reading device and the hacking prevention vehicle information transmitting device 300 generally do not transmit and receive data using a predetermined protocol, but simply receive image data transmitted to the monitor 56. Such output image data is generally pixel-based data (color, etc.), and such data is data meaningless from the viewpoint of data processing. Therefore, there may be no physical connection between the vehicle information reading device and the anti-hacking vehicle information transmitting device, so there is no fear of hacking.

The data acquisition unit 320 will be described in more detail as follows.

In general, the conventional output method from the computer to the monitor (that is, the output method to the monitor 56 of the operation control unit 50 of the vehicle information reading apparatus) is divided into a digital signal output method and an analog output method. Digital DVI (Digital Video Interface) is a new form of video interface technology designed to maximize the quality of high-end graphics cards and advanced display devices, including LCD monitors. Most LCD monitors on the market are used to connect computers. HDMI (High-Definition Multimedia Interface) is a format that integrates video and audio signals into one digital interface, and is used in A / V devices such as DVD players, HDTVs, and set-top boxes. On the other hand, the analog output method is based on the RGB video signal method, which is the conventional PC-based monitor output method, and includes the composite video signal, the S video (SUPER VIDEO), and the component video signal system. The excellence of HDMI>DVI> RGB video signal>Component>S-Video> Composite.

In order to secure the performance of image processing among the various image output methods described above, it is preferable to use an RGB video signal or a digital image output method.

Looking at the method of obtaining the output to the monitor 56 of the operation control unit 50 of the vehicle information reading apparatus described above by the image data acquisition unit 320 of the anti-hacking vehicle information transmitting device 300 as follows.

The image output to the monitor 56 of the operation control unit 50 of the vehicle information reading apparatus can be obtained using, for example, a frame grabber board or a video capture board. Frame grabber is an image equipment that digitizes analog video signal displayed through video media such as television (TV), CCD camera, etc. into a signal that can be processed by personal computer (PC) by digitizing it into defined bits per sample. A device collects images at a scanning speed to be scanned at and stores the input images in a storage device in a computer or a storage location for a special image storage. Therefore, it is preferable that a data grabber uses a frame grabber board capable of receiving an excellent image and processing the image signal digitally.

Meanwhile, the controller 310 receives an image acquired by the data acquirer 320 through a frame grabber, etc., and processes and extracts necessary information-vehicle information-from the received image by image processing. The vehicle information includes at least the contents of the license plate and preferably further includes a shooting location, a shooting time, and the like. As a method of recognizing letters, numbers, and the like by processing an image, there are pattern recognition techniques known in the field of image processing, and thus a detailed description thereof will be omitted.

Meanwhile, the vehicle information extracted by the controller 310 may be transferred to the arrangement information device 250 of FIG. 1 through the interface unit 340. In addition, the format of the interface unit 340 is not limited.

The arrangement information (250 of FIG. 1) compares the received vehicle information in real time with the arrangement database (255 of FIG. 1), for example, theft, arrangement, delinquent vehicle database, and if the vehicle is found, Arrests can be made by notifying the police station of the vehicle location or other expected route. Of course, the comparison between the extracted vehicle information and the wanted vehicle database may be performed by the hacking prevention vehicle information transmitting device 300.

On the other hand, in the present embodiment it is shown that the image obtained on the monitor 56 of the operation control unit 50 of the anti-hacking vehicle information reading device to obtain from the data acquisition unit 320 of the anti-hacking vehicle information transmitting device 300 And described, but the present invention is not limited thereto. For example, the image output to the printer 58 of the operation control unit 50 of the vehicle information reading apparatus, the monitor of the field control unit (30 in FIG. 1) of the vehicle information reading apparatus, the image or camera portion output to the printer It is also possible to obtain the image output from (10 of FIG. 1) by the data acquisition unit 3320 of the vehicle information transmission device for preventing hacking.

On the other hand, as shown in Figure 4, the data acquisition unit 320 of the anti-hacking vehicle information transmitting apparatus 300 according to the present invention can use the image 500 taken by the conventional vehicle information reading device as it is. However, it is desirable to process such an image 500 properly. Because, although the data acquisition unit 320 simply acquires the image, the control unit 310 of the anti-hacking vehicle information transmission device 300 performs image processing again to extract the vehicle information. Therefore, if possible, it is preferable that the control unit 310 processes (converts, processes) the image in the operation control unit 50 of the vehicle information reading apparatus and outputs the image as shown in FIG. Do. Of course, even when the image is processed by the operation control unit 50 of the vehicle information reading device, the data acquisition unit 320 of the vehicle information transmission device 300 for preventing hacking acquires data in the form of an image.

Referring to Figures 4 and 5, it will be described in detail as follows.

In general, the field control unit 30 of the vehicle information reading apparatus performs image processing on the vehicle information such as the license plate 510 in the captured image and reads it. Therefore, it is preferable to make the read vehicle information 520 into an image, but convert the vehicle information 520 into an image that is easily converted by the controller 310 of the anti-hacking vehicle information transmission device for image processing. That is, the vehicle information reading device preferably further includes an image processing unit for processing at least the license plate information so as to facilitate image processing by the control unit of the delivery device. The image processing unit may be made separately, or may be performed in the field control unit or the operation control unit.

The reason for this is that after the license plate is recognized by the field control unit, since the resolution is generally reduced or compressed and transmitted to the operation control unit in the form of an image, such an image may be difficult to recognize in the control unit 300 of the vehicle information transmission device for preventing hacking. Because there is. However, since the vehicle information reading apparatus already has the vehicle information in a form that can be actually recognized (for example, text data) 520, it is possible to make it into an easy-to-recognize image and deliver it to the delivery device in the form of an image. to be.

An example of image processing is as follows.

For example, image processing may be performed as shown in FIG. 5. The vehicle information 520 read out from the original image 500 in the vehicle information reading device may be enlarged in large and clear to create a new image 600 (hereinafter referred to as "processed image" for convenience). In the processed image 600, the vehicle information 610 may be large and clear. In addition, it is preferable that the vehicle image 620 (corresponding to the original image 500 in the vehicle information reading apparatus) be made small and included in the processed image 600. In such a configuration, the control unit of the anti-hacking vehicle information transmitting apparatus does not need to process the image of the vehicle image 620 in the processed image 600, but needs to image the vehicle information image 610 only.

Furthermore, the vehicle information image 620, that is, the license plate of the vehicle is composed of Korean and Arabic numerals, and the recognition of the Hangul is accompanied by more effort and misrecognition than the recognition of the numbers. Therefore, in order to solve this problem, it is preferable that the vehicle information image 620 is uniformly outputted from the processed image 600 and the number is recognized in the recognition process. The number of the vehicle is based on "2005-334 of the Ministry of Construction and Transportation". For example, Jeonbuk 29-ga 1234 is a symbol mark of the jurisdiction of "Jeonbuk", and "29" is a car type classification code. Are assigned up to "01 ~ 99", 01 ~ 69 are passenger cars "70 ~ 79 are vans, 80 ~ 97 are cargo 99, 99 are classified as special vehicles. The symbol is classified into (a), (b), ... (32), and is given as a serial number of "1234." In order to read the vehicle number from the vehicle information image 620, the jurisdiction authority symbol and the vehicle formed in Korean The type code and serial number of a vehicle consisting of a delimiter and a number should be read in. However, in order to recognize the character quickly, it is difficult to recognize the character, so as to exemplarily set the rules as illustrated in FIG. Convert the display to a number It is good to make an image, that is, Jeonbuk can be printed by replacing with two digits in the "01" and Jeonnam "02" method, and the use symbol of the vehicle can also be substituted by "01". Therefore, as shown in Fig. 7, when the vehicle number "Jeonbuk 84ga 3912" is reconstructed, it is possible to express "01,84,01,3912" (600a), that is, 10 digits. It is more preferable to configure and operate a table which adds a predetermined area code and a shooting time code by adding a code, a shooting time, etc. (for example, the last "01" in the vehicle information image 600a in FIG. 7).

로 디지털 숫자형태의 표현이 바람직하다. 도 7은 디지털 타입의 글자체를 이용한 것이다. 또한 상기의 숫자화된 데이터를 인식이 용이한 바코드(BAR CODE) 형태로 출력하고 이를 인식하는 것도 가능하다. Furthermore, in order to increase the speed of recognition, in addition to digitizing the location information or the Hangul, it is preferable to set the font to be easily recognized in the case of numbers. In order to increase the recognition rate and increase the recognition speed, it is preferable to output the digital font. In other words, "01,29,01,1234" means "for ease of numeric recognition."

Digital representation of numbers is preferable. 7 uses a digital type font. In addition, it is also possible to output the digitized data in a bar code form for easy recognition and to recognize it.

On the other hand, as shown in Figure 7, the output unit of the anti-hacking vehicle information transmission device 300, it is preferable to display the vehicle image 620 and the vehicle information image (license plate information) 600a at the same time. In this case, the image 620 of the vehicle is stored in a predetermined memory device, and the vehicle information is extracted from the vehicle information image 600a and compared with the wanted vehicle database (for example, 255 of FIG. 1) to meet a predetermined condition. If so, the vehicle image 620 may be displayed.

In addition, in the case of the digitized vehicle information image 600a, for example, the first two digits may be used to intuitively recognize the converted number for easy processing and recognition of the image such as jurisdiction display and usage indication. 01 "is preferably replaced with" Jeonbuk "and displayed. Of course, it is preferable to convert the display area, the shooting date, the vehicle type, etc., which have been converted to numbers, to be converted back to characters.

Meanwhile, as illustrated in FIGS. 8 and 9, the image 500a output to the monitor 56 of the operation control unit 50 of the vehicle information reading apparatus is shot again by the camera 360 to hack the captured image. It is also possible to obtain from the data acquisition unit 320 of the prevention vehicle information transmission device. In this case, it is preferable that the image displayed as shown in FIG. 9 is converted and displayed as shown in FIG. 10.

In this case, a predetermined space and distance are required to shoot in the camera, and in particular, a stable illumination and a stable space for fixing the camera are required. In this case, the method of inputting the camera image for the stable operation of the anti-hacking vehicle information transmission device is IEEE.1394, USB, ETHERNET, etc., it is preferable that no additional device is required for an interface. Do.

On the other hand, the vehicle information reading apparatus according to the present invention is not limited to the security vehicle information reading device using a security CCTV installed by the local governments or national police, it is of course also possible to use the other device for reading the vehicle number. .

For example, an illegal parking unmanned enforcement system, a parking control system that permits a vehicle to enter or settle a parking fee by recognizing the number of a vehicle, and is usually mounted on a vehicle to arrest an arranging vehicle, or to crack down on illegal parking The present invention can also be applied to a vehicle information reading device and the like operated for the detection of the present invention.

According to the present invention, it is possible to obtain a surveillance network of a large number of vehicles by enabling real-time monitoring and arrest of arranging, stolen, and arrears vehicles using data transmitted from a large number of vehicle number reading devices for different uses. .
