AN AUTOVEHICLE CHECK SYSTEM

Abstract: The parity bar codes are arranged side by side adjacent to data bar code. Reference bar codes having a predetermined length and width are positioned adjacent to the data bar code and parity bar code, respectively, a bar code identification scanner compares actual identification data code and parity bar codes with the reference bar codes with a bar code identification angle being changed during the running of an autovehicle and corrects the data code and parity bar codes adjacent to each of reference bar codes by the angle difference between the actual code and the identified code as well as reads them. The corrected data are stored as the identification data at an inner RAM of the scanner. The parity data are decoded to make the scanner judge whether the identification data are error. Next, if the identification data are error, the identification data is canceled. If not, the other parity code is checked, once more. If not, only the identification data are transmitted as the actual data to a regional computer or a central computer. Thus, the autovehicle check system can exactly determine at least one bar codes adhered to a predetermined place of autovehicles, so that it may effectively manage a highway or a trunk road relative to autovehicles.

Description: SPECIFICATION TITLE OF INVENTION An Autovehicle Check System TECHNICAL FIELD The invention is related to provide an autovehicle check system, and particularly to provide an autovehicle check system using a bar code. BACKGROUND ART A bar code has been usually used in two types, one type of which is relative to the use of a visible paint and other type of which is relative to the use of an invisible paint. Due to the inherent properties of these paints, the visible paint can be duplicated by a copier and a desk top publishing to issue a plurality of goods codes. This have been adapted to the sale and inventory adjustment of articles, but has been not yet used in the social security system against the possibility of the forgery. The invisible paint can be adapted to the social security system if it is an ultraviolet ray ink or a commercial specific ink. In light of these points, it is noted that the invisible paint can obtain a high effect accompanying to the social security system. For example, if the commercial specific paint is coated on a license plate, the license plate can be seen with a naked eye, but the bar code is identified by only a CCD camera and an invisible bar code identif cation scanner. On the other hand, at the present autovehicles made a bad use in a great criminal act were being almost robbed or lost. Thus, it is known that it is advantageous to run after/find the robbed or lost autovehicles at the first stage. That is to say, when a person reports his lost autovehicle to a police, the autovehicle is arranged for the search of an identified criminal in the whole country. At that time, the identification function is rendered to an autovehicle having a bar code, in manner that an invisible code identification scanner mounted on a trunk road reads the invisible bar code, or a police on duty or third parties having a question identifies a visible bar code painted on the predetermined area of an autovehicle to expose a robbed autovehicle to public persons. It can leads the previous prevention of a plurality of undesirable accidents. Also, the bar code can remove the factor of the autovehicle traffic stagnation due to the collecting of a toll corresponding to user's destination at the toll station of an expressway. Concretely, autovehicle identification numbers discriminated by a bar code identification scanner can make possible the deferred payment of a toll based on the calculation of the traveling distance from the entry place to the destination place or exit of a highway. Furthermore, the printing of a bar code can represent various informations of autovehicle numbers, colors, models and the dates of its production, which are registered in every register offices of the whole country. It is easy to identify the autovehicles lack of a record concerning the changing of the numbers and colors, etc. , which are forged to the robbed autovehicles. Then, it has been tendency to use a bar code within the limited range of goods production, sale, stock-taking and autovehicle production and the management of a warehouse, etc.. If a bar code is adapted to autovehicles, the use of a bar code can be changed accompanying that a system using the communication network of the country be constructed. Also, it is obvious that the system has not been accomplished. This is the innovatory thing in light of the above points. The main object of the invention is to provide a scanner discriminating a square matrix bar code. The other object of the invention is to provide an autovehicle check system for tracing and identifying the robbed autovehicle using a bar code. Another object of the invention is to provide an autovehicle check system for allowing the future payment of a toll charged to the use of a highway. DISCLOSURES OF INVENTION Accordingly, the invention comprises bar codes of at least one types having various informations of autovehicles, a plurality of detecting apparatuses spraying a visible or invisible paint to a suspects autovehicle and a plurality of bar code identification scanners discriminating a bar code, the detecting apparatus and the scanner being mounted together or alone at one place, at least one regional slave computers connected to each of the scanners and a central host computer having all the regional slave computers connected thereto. The visible or invisible bar code has informations of autovehicle secret numbers, colors and features and is painted on a license plate or a predetermined place exposed effectively to public persons. The detecting apparatus has the data of an autovehicle to be searched by a police to detect the suspicuous autovehicle. The scanner identifies a bar code of autovehicles to collect informations of autovehicles entered into a highway or a trunk road as well as to send autovehicle informations to the regional slave computer. The regional slave computer analyzes information received thereby to transmit informations of autovehicles instituted and toll calculating data of autovehicles passing through a toll station on a highway or a trunk road. The central host computer classifies informations of suspicuous autovehicles to store classified data at the data base to command the arrangement of robbed or lost autovehicles to a police, while it receives the reports of the robbed autovehicles from a plurality of persons subscribed to a telephone station. The central host computer can be provided with an audio teletext or a video teletext. Also, the invention comprises a square matrix code including one or two data bar codes, at least one parity bar codes and at least two reference bar codes formed at the outmost adjacent to the data bar code and one of parity codes. For example, it is easy to identify a simple bar code formed as single or two lines with autovehicles being traveled at a low speed or stopped. But, the rate of the identification relative to autovehicles running at an irregular speed or direction is inevitably and remarkably reduced. As to it, the size of a bar code including length and breadth can be enlarged to adhere it to autovehicles in order to increase the bar code identification rate. If a bar code is made of a visible paint, autovehicles are ill- effected on their appearances. If a visible bar code is written by a specific paint on the front glass of autovehicles, it causes the obstruction of the driving view. Therefore, when the parity bar code is arranged adjacent to the data bar code, and also reference bar codes having a predetermined length and width are positioned adjacent to the data bar code and parity bar code, respectively, a bar code identification scanner compares actual identification data code and parity bar codes with the reference bar codes with an bar code identification angle being changed during the running of an autovehicle as well as corrects the data and parity bar codes adjacent to each of reference bar codes by the angle difference between the actual code and the identified code and then reads them. The corrected data are stored as the identification data at an inner RAM of the scanner. The parity data are decoded to make the scanner judge whether the identification data are error. Next, if the identification data are error, the identification data are canceled. If not, the other parity code is checked, once more. If not, only the identification data are transmitted as the actual data to a regional computer or a central computer. Thus, the invention can exactly discriminates at least one bar codes adhered to a predetermined place of autovehicles, so that it may effectively manage a highway or a trunk road relative to autovehicles. BRIEF DESCRIPTION OF DRAWINGS The invention will be explained in detail by the reference to the accompanying drawings, in which: Fig.1 is a schematically view showing an example of a trunk road mounting a bar code identification scanner according to the principle of the invention, Fig.2 is a view showing an example adapting a bar code to autovehicles according to the principle of the invention, Fig.3 A, B, C and D are views illustrating bar codes adapted to autovehicles according to the principle of the invention, Fig.4 is a schematically block diagram illustrating an autovehicle check system according to the principle of the invention, Fig.5 is a flow chart illustrating the procedures identifying a bar code according to the principle of the invention. BEST MODE FOR CARRYING OUT INVENTION As illustrated in Fig.1, all informations associated with autovehicle entering into high way 2 at access road 1 of a trunk road or traveling into other trunks road 3 or 4, or 5 is read at the entry of highway 2 or a trunk road to automatically send them to the data base of a central computer. All informations may be written as a visible code or an invisible code. Thereafter, all informations corresponding to autovehicles passing through trunk road 5 as shown in the drawing is read at its entry to get a bar code identification scanner to analyze them as wel.l as to classify them into the data for the deferred payment of a toll and the data for autovehicles searched by a police, and is sent to the data base of a central computer to go ahead next steps related with corresponding autovehicles based on the data analyzed. As showed in Fig.2, a code of an invisible or a visible paint and ink may be coated on the license plate. If the paint is a visible code, this code may be printed on the area in any sides of autovehicles which can be exposed in maximum to public persons. Bar code 7 printed can covers all informations having the features of autovehicles like the bar code of commercial articles. As showed in Fig.3 C, a square matrix code includes one data code b and two parity codes c, d side by side adjacent to each another and two reference codes having a predetermined length and width. Each of reference codes a and e is arranged at the lower and upper of data code b and parity code d. The square matrix bar code is identified by a bar code identification scanner with being changed by an identification angle having the angle difference between the actual bar code and the identification bar code as shown in Fig.3 D. As shown in Fig.5, a bar code identification scanner recognizes a square matrix code through the operation of the following steps. A scanner captures a matrix code printed on a predetermined place of autovehicles at step 101, even through the matrix code has an identification angle (Fig.3 D) during the running of autovehicles. Next, the scanner compares each of reference codes a and b with data code b and parity codes c and d, and data code b and parity codes c,d are corrected by a microprocessor or a control circuit based on an identification angle of a reference of a bar code at step 102 to recognize as a normal matrix code of Fig.3 C. The identification data corrected is stored at a RAM of the scanner at step 103. Any one of parity codes c and d is decoded at step 104. Step 104 moves on step 105 to judge according to the result of decoding one parity code whether an identification data code is error. If an identification data code is error, step 105 returns to step 101 to cancel the error data as well as to capture other matrix code. If an identification data code is correct, step 105 goes on step 106 to judges according to the result of decoding other parity code whether an identification data code is error. If an identification data code is error, it is again judged. If not, reference codes a and e are removed, and only the identification data are sent to a central computer described below in detail. The square matrix code can be adapted to an autovehicle check system as shown in Fig.4. As shown in Fig.4, bar code identification CCD camera or bar code identification scanners 10, 11 and 12 are mounted on the entry and exit of a highway or trunk road in the whole country to read the numbers, colors and secret code related with autovehicle informations. These scanners 10, 11 and 12 each may be provided with detecting apparatuses 13, 14 and 15 for detecting autovehicles searched by a police mounted adjacent thereto. Detecting apparatuses 13, 14 and 15 can recognize autovehicles arranged for the search of a criminal act. If they identify the instituted autovehicle, detecting apparatuses 13, 14 and 15 jet an invisible paint or visible paint on a predetermined place of autovehicles to be exposed to public persons or polices for announcing the lost or robbed facts of autovehicles. These scanners and detecting apparatues are connected to the corresponding regional computers, respectively or together. Regional computer 16 is provided with a data base for the management of the deferred payment of a toll charged to autovehicles passing through a highway or a trunk road as well as for the transmission of all informations concerning autovehicles searched by a police to central computer 18. Central computer 18 is provided with an audio teletext or a video teletext. Also, central computer 18 is provided with telephone communication network system 19 to receive reports of autovehicles robbed or lost from telephone subscriber 22, 23 and 14, etc. through telephone communication network 20. Therefore, central computer 18 collects informations with respect to autovehicles searched by a police from regional computer 16 and informations from telephone subscribers 22, 23 and 24, stores them at its data base, and analyzes them thereby to order the arrest and arrangement of robbed autovehicles to the corresponding regional police offices. As described above, the invention allows the monitor and discernment of autovehicles traveling on all roads in the whole country. With it, it is easy to manage a toll charged to all autovehicles passing through a highway or trunk road as well as arrest autovehicles instituted, thereby allowing the previous prevention of miserable accidents. Particularly, the square matrix code of the invention allows the accurate data read even though autovehicles is being traveled, in the manner that a code identification angle occurred by the velocity and direction of autovehicle is corrected by a reference code and a data code is judged by a parity code whether it is correct.
