Description

  The present invention relates to a detection device and a theft bicycle detection system for finding a stolen bicycle from a large number of parked bicycles and the like.

  The current discovery of stolen bicycles is made by police officers, etc., who are traveling around the world, looking at the crime prevention registration number of the abandoned bicycle and inquiring the crime prevention registration number from the police's information center. Alternatively, the security registration number is copied, and after returning to the dispatch office, processing such as inquiries is performed. For this reason, it takes a considerable amount of time to find a stolen bicycle. Therefore, it is not realistic to discover stolen bicycles from a large number of abandoned bicycles in places where a large number of bicycles are left. In addition, even if a theft report is actually issued, the rate at which the bicycle is returned to the owner is about 30% to 40%.

  Based on the current situation as described above, if there is a system that can determine a stolen bicycle in a short time, it will be possible to check not only for abandoned bicycles but also for bicycles that are parked properly. It seems that the discovery rate of bicycles can be dramatically increased.

  For this reason, in the invention according to Patent Document 1, the work efficiency is improved by reading and collating the crime prevention registration number of the crime prevention seal. However, since the invention according to Patent Document 1 does not assume a case where a large number of bicycles are inspected in a short time, it places a burden on the workers on the site. For example, in most cases, a bicycle security sticker is stretched under the frame, and an operator has to reach the lower side of the bicycle with the portable terminal body. This is not suitable for testing a large number of bicycles.

(Embodiment 1)
FIG. 1 is a conceptual diagram showing a stolen bicycle discovery system according to Embodiment 1 of the present invention. FIG. 2 is a side view showing a detection device of the stolen bicycle detection system shown in FIG. FIG. 3 is an enlarged view showing a tip of the detection device of FIG. FIG. 4 is an explanatory diagram illustrating an example of a usage state. FIG. 5 is a block diagram showing a stolen bicycle discovery system.

  The stolen bicycle detection system 100 includes a detection device 1 and a mobile terminal 2. The detection device 1 is used by an operator and is used for reading the number of the security seal, and includes a grip 3 gripped by the operator, a telescopic rod 4 extending from the grip 3, and a rod 4 And a detection unit 5 provided at the end of the above. The detection unit 5 is mounted in a movable state by two orthogonal rotating shafts 6 and 7. In addition, you may attach the detection part 5 to the rod 4 with a universal joint or a ball joint. Thereby, the detection part 5 becomes movable in the left-right direction and the up-down direction. Further, the vicinity of the tip of the rod body 4 is constituted by a flexible tube 8 that can maintain a bent state. The rod body 4 has a structure in which a plurality of pipe members having different cylinder diameters are sequentially inserted, and can be freely expanded and contracted.

  As shown in FIG. 3, the detection unit 5 has a structure in which two CCD (Charge Coupled Device) cameras 10 are provided inside a curved housing 9, and the inside (front side) of the housing 9 is a transparent plate 11. Is provided. The CCD camera 10 includes a CCD image sensor and an imaging lens arranged in front of the CCD image sensor. Also, columnar projections 12 that abut against the bicycle tube T (curved surface) are provided on both side edges of the housing 9. The cylindrical protrusion 12 is preferably made of a material having a high frictional force such as rubber. The left and right CCD cameras 10 are arranged in one direction with a certain angle K. The angle is preferably 90 degrees or more and 150 degrees or less. An LED light 13 is provided inside the housing 9 and between the left and right CCD cameras 10.

  As shown in FIG. 3, the detection unit 5 is positioned with respect to the tube T by pressing the cylindrical protrusion 12 of the detection unit 5 against the curved surface of the tube T. Thus, the left CCD camera 10L is opposed to the left surface TL of the tube surface and the right CCD camera 10R is positioned on the right side TR of the tube surface by pressing and positioning the detection unit 5 against the portion to which the security seal is attached. Will be opposite. Further, the LED light 13 provided in the center of the housing 9 is also opposed to the tube surface at a constant interval.

  Further, since the cylindrical protrusion 12 abuts on the tube surface in a straight line, it can be positioned with respect to the tube TA and the tube TB having different diameters as shown in FIG. Further, the flexible tube 8 can hold the deformed state. For example, as shown in FIG. 4, the tip of the rod body 4 can be bent into a U shape and the state can be maintained. Thereby, when the crime prevention seal is stretched on the front side of the seat tube of the bicycle, the detection unit 5 can be pressed against the surface of the crime prevention seal from the back of the bicycle by bending the flexible tube 8.

  In the grip 3, an A / D conversion unit 21 for A / D converting an image detected by the CCD camera and an image captured by the left and right CCD cameras 10 are combined, and a security registration number displayed on the image is written in characters. An image processing unit 22 that is recognized as information, an identification number providing unit 23 that assigns an identification number to a crime prevention registration number, a storage unit 24 that stores an image assigned with an identification number, and a display unit that displays a synthesized image 25, a communication unit 26 that transmits image data to the mobile terminal 2, and a power source 27 such as a secondary battery.

  The mobile terminal 2 includes a display unit 28 that displays an image received from the detection device 1, a collation unit 30 that transmits the displayed image to a server owned by the police and requests collation, and obtains a collation result. A communication unit 31 that communicates with the system and a position information adding unit 29 that adds position information to the acquired image are configured. The portable terminal 2 may be a dedicated terminal, but may be configured by incorporating a predetermined program in a portable general-purpose computer such as a PDA (Personal Digital Assistant).

  The police system 32 includes a communication unit 33 that communicates with the mobile terminal 2, a server 34, and a database 35 that stores a crime prevention registration number of a stolen bicycle.

  Next, the operation of the stolen bicycle discovery system 100 will be described. FIG. 6 is an explanatory diagram showing the operation of the stolen bicycle discovery system. 7 and 8 are flowcharts showing the operation of the stolen bicycle discovery system. The stolen bicycle detection system 100 is often used in a place where a plurality of bicycles are parked side by side. The operator looks for the security seal S that is attached to the frame of the bicycle to be inspected with the grip 3 of the detection device 1. Then, the detection unit 5 is pressed against the portion where the security seal S is stretched. Thereby, the cylindrical protrusions 12 on both sides of the detection unit 5 come into contact with the tube T, and the detection unit 5 is positioned with respect to the tube T.

  When the photographing button 36 of the grip 3 is pressed, the LED light 13 in the housing 9 is turned on to illuminate the tube T on which the security seal is stretched, and the CCD camera 10 captures the security seal stretched on the tube T. (Step 1). As a result, the left CCD camera 10L acquires an image of the left half of the tube, and the right CCD camera 10R acquires an image of the right half of the tube (step 2). For example, as shown in FIG. 6, the left CCD camera 10L obtains an image 51 including the number “J24947” of the security seal, and the right CCD camera 10R receives an image 52 including the number “4763” of the security seal. get.

  Next, as shown in FIG. 6, the image processing unit 22 connects and synthesizes the security seal images 51 and 52 taken by the left and right CCD cameras 10 into one continuous image 53 (step 3). A method for connecting and synthesizing images is performed using a known program.

  Next, the image processing unit 22 reads the crime prevention registration number displayed in the connected image 53 as data by character recognition (step 4). The read crime prevention registration number information is displayed on the display unit 25 of the detection device 1. Moreover, the detection apparatus 1 judges whether the crime prevention registration number was read correctly (step 5). If the character recognition cannot be performed correctly, an error is displayed on the display unit 25 (step 6). Further, a warning sound such as a buzzer is generated along with the error display using a warning sound generating device such as a speaker (not shown). In this case, steps 1 to 5 are performed again.

  Next, the identification number assigning means 23 assigns an identification number to the crime prevention registration number information that has been character-recognized (step 7). For example, as shown in FIG. 6, the identification number “001” is assigned to the security registration number information “J2494763”, the identification number “002” is assigned to the security registration number information “J5837349”, and the security registration number information “J10940475” is assigned. ID number “003” is assigned. The reason why the identification number is given to each crime prevention registration number information is to make it possible to determine the approximate location of the stolen bicycle when a plurality of bicycles are collectively referred to the police system. For example, when inquiring the police for crime prevention registration number information of 30 bicycles, it is troublesome to specify a stolen bicycle on the spot by using only the crime prevention registration number as a landmark. For this reason, if an identification number is assigned as the shooting order, it is easy to find a stolen bicycle (since it is only necessary to determine what number the bicycle corresponds to). The registration number information given the identification number is stored in the storage unit 24 of the detection device 1 (step 8).

  Subsequently, it is determined whether or not the crime prevention registration number for the next bicycle is acquired (step 9). Specifically, the shooting is automatically continued by pressing the shooting button 36 of the grip 3 (return to step 1). On the other hand, when shooting is finished, the shooting end button 37 is pressed. Thereby, the crime prevention registration number information memorize | stored in the memory | storage part 24 is transmitted to the portable terminal 2 (step 10). The portable terminal 2 receives the crime prevention registration number information and displays it on the display unit 28 (step 11). The portable terminal 2 includes a GPS (Global Positioning System) device 38, acquires position information by the GPS device 38, and assigns the position information to all the security registration number information received (step 12). . For example, as shown in FIG. 6, information of “Kagamiyama 3-chome, Higashihiroshima-shi, Hiroshima” is given as position information to all crime prevention registration number information.

  Next, the collation part 30 of the portable terminal 2 connects to the police system 32 (step 13), and transmits the stored crime prevention registration number information (step 14).

  The police system 32 receives the crime prevention registration number information after confirming that the mobile terminal 2 is permitted to access (step 15). In the police system 32, the received crime prevention registration number is collated with the crime prevention registration number relating to the stolen bicycle accumulated based on the theft report or the like (step 16). If it is determined that the bicycle is a stolen bicycle as a result of the collation (step 17), the result is stored as “theft bicycle” (step 18). This collation is performed for all of the received crime prevention registration number information, and all the results are stored for those judged to be stolen bicycles. Then, the police system 32 transmits the stored verification result to the portable terminal 2 (step 19).

  The portable terminal 2 receives this collation result (step 20), and the collation unit 30 displays information on “theft bicycle” in the collation result (step 21), as shown in FIG. In 25, the collation result “theft bicycle”, the identification number “0003” given to the crime prevention registration number information, and the crime prevention registration number “J1098475” are displayed (step 22). While referring to the identification number, the worker registers a bicycle that seems to be a stolen bicycle, visually checks the crime prevention registration number of the bicycle, and identifies the bicycle as a stolen bicycle. The operator performs predetermined measures such as locking the stolen bicycle. Then, a report of treatment is made from the portable terminal 2 to the police system 32 (step 24). For example, information indicating that a predetermined process with the police, such as locking the key, has been performed is transmitted from the mobile terminal 2 to the police system 32.

On the other hand, if the collation result does not include a stolen bicycle, “no stolen bicycle” is displayed on the display unit 25 (step 23).

  The police system 32 stores the result of the treatment for the stolen bicycle (step 25), and notifies the owner who registered the e-mail address when reporting the damage (step 26). At this time, since the position information given in the portable terminal 2 is sent at the same time, the owner can confirm the approximate location where the bicycle is present. At the time of filing this application, no e-mail is registered, so police officers individually contact the owner by phone or letter. Also, follow the agreement between the police and the owner on how to pick up stolen bicycles.

  As described above, according to the stolen bicycle detection system 100, it is possible to easily determine the stolen bicycle by reading the crime prevention registration number easily and accurately and comparing it with the police system 32. Further, the detection device 1 can be used easily without the operator bending down or taking an unreasonable posture because the detection unit 5 can move freely, can be extended and contracted to adjust its length, and can be bent freely. it can.

  In addition, by adding location information to the crime prevention registration number information of the stolen bicycle, the police can compare the stolen location included in the damage report with the location information and obtain statistics such as the travel distance and location of the stolen bicycle. . Such statistics can be used for future bicycle theft countermeasures.

  Alternatively, the worker information may be stored in the portable terminal 2 and the worker information may be added to the crime prevention registration number information. As a result, the bicycle handled by the worker can be specified. Also, the police can grasp information such as the number of crime prevention registration number information for each worker, the number of stolen bicycles found, and the working time. For example, the time included in the security registration number information transmitted first is set as the work start time, and the time included in the security registration number information transmitted last is set as the work end time. You can get time. Moreover, the workload for each worker can be measured from the number and time of crime prevention registration number information.

  FIG. 9 and FIG. 10 are explanatory diagrams illustrating modifications of the detection device 1. The detection device 1 has substantially the same configuration as the detection device 1, but the structure of the tip of the rod 4 is different. Since other structures are the same as those of the detection apparatus 1, the description thereof is omitted. The distal end of the rod body 4 is provided at the distal end of the rotation shaft 62 of the first movable portion 61 and orthogonal to the rotation shaft 62. And a second movable portion 63 that rotates in the direction. The detection unit 5 is rotatably provided by the second movable unit 63 with respect to the rotation shaft 62. The length of the rotation shaft 62 is longer than half of the width of the detection unit 5. The detection unit 5 can be rotated 180 degrees by the second movable unit 63. The rod body 4 has an expansion / contraction structure similar to that of the detection device 1.

  The operation of the detection device 1 will be described. When photographing the security seal S stretched on the front surface of the seat tube T from the front of the bicycle, the detection unit 5 is positioned between the frames from the front of the bicycle and the detection unit 5 is rotated so that the photographing surface faces the front. Subsequently, the cylindrical projection 12 of the detection unit 5 is pressed against the curved surface of the seat tube T while pushing the detection device 1 forward. The seat tube T is usually inclined with respect to the ground, and the detection unit 5 is rotated by the first movable unit 61 with respect to this inclination. Then, the security seal S is photographed in this state.

  Next, when the security seal S stretched on the front surface of the seat tube T is photographed after the bicycle, the detector 5 is positioned between the frames from the rear of the bicycle and the detector 5 is rotated so that the photographing surface is Then, the cylindrical protrusion 12 of the detection unit 5 is pressed against the curved surface of the seat tube T while pulling the detection device 1 backward. The seat tube T is usually inclined with respect to the ground, and the detection unit 5 is rotated by the first movable unit 61 with respect to this inclination. Then, the security seal S is photographed in this state.

Further, when photographing the security seal S stretched on the front surface of the seat tube T from the side of the bicycle, the detection unit 5 is positioned between the frames from the side of the bicycle and the detection unit 5 is rotated so that the imaging surface is rotated. Then, the cylindrical protrusion 12 of the detection unit 5 is pressed against the curved surface of the seat tube T while moving the detection device 1 sideways. In general, the seat tube T is inclined with respect to the ground, and the detection unit 5 is brought into good contact with the tube T by slightly tilting the grip 3 with respect to the inclination. Then, the security seal S is photographed in this state.

  In this way, by providing the detection unit 5 in a movable state at the tip bent into a substantially L shape, it is possible to easily shoot even when the security seal S is attached to the front side, back side or side of the operator. become able to.

(Embodiment 2)
The stolen bicycle detection system according to the second embodiment is an example in which an IC tag is used instead of the crime prevention registration seal. FIG. 11 is a conceptual diagram showing a stolen bicycle discovery system according to Embodiment 2 of the present invention. FIG. 12 is a side view showing the detection device of the theft bicycle discovery system shown in FIG. FIG. 13 is an enlarged view showing the tip of the detection device of FIG. FIG. 14 is a configuration diagram showing the stolen bicycle discovery system 200. An IC tag is affixed to a place on the bicycle frame with a seal, and the bicycle crime prevention registration number and other information are stored on this IC tag (the owner's name, address, contact information, etc. are leaked of personal information) Is not remembered because it leads to The theft bicycle discovery system 200 includes a detection device 201 and a mobile terminal 2. In addition, the same code | symbol is attached | subjected about the same component as the theft bicycle discovery system 100 of Embodiment 1, and the description is abbreviate | omitted.

  The detection device 201 is used by an operator for holding and reading a crime prevention registration number, and includes a grip 3 gripped by the operator, a telescopic rod 4 extending from the grip 3, a rod The detection unit 205 is provided at the tip of the body 4. The detection unit 205 is attached in a rotating state in one direction by a rotation shaft 206. The detection unit 205 has a flat plate shape and is provided with a passive RFID (RA / Dio Frequency IDentifICation) antenna 207 which is a wireless short-range communication means. Further, a cushion material 212 is provided on the surface of the detection unit 205. The cushion material 212 is urethane, sponge, silicon rubber, or the like. It is assumed that the thickness of the cushion material 212 is smaller than the reading distance of the IC tag. For example, if the reading distance is 3 cm, the thickness is preferably 2 cm or less.

  Further, the cushion material 212 can prevent the casing of the detection unit 205 from hitting the bicycle frame and damaging the bicycle frame, and can also prevent troubles caused by damaging the bicycle frame. Moreover, the sound generated by hitting the bicycle frame can be reduced. In particular, since the detection unit 205 is separated by the rod 4, it is not possible to perform delicate position adjustment by the operator's hand. Therefore, if the cushion material 212 is pressed against the frame, the work becomes easier.

  Further, the vicinity of the tip of the rod body 4 is constituted by a flexible tube 8 that can maintain a bent state. The rod body 4 has a structure in which a plurality of pipe members having different cylinder diameters are sequentially inserted, and can be freely expanded and contracted.

  In the grip 3, an RFID reader 222 connected to the antenna 207, an identification number giving unit 23 for giving an identification number to the crime prevention registration number information acquired by the RFID reader 222, and a crime prevention registration given an identification number A storage unit 24 that stores number information, a display unit 25 that displays the acquired crime prevention registration number, a communication unit 26 that transmits image data to the mobile terminal 2, and a power source 27 such as a secondary battery are provided. ing.

  Next, the operation of this stolen bicycle detection system will be described. FIG. 15 is an explanatory diagram showing the operation of the stolen bicycle discovery system. FIG. 16 is a flowchart showing the operation of the stolen bicycle discovery system. The stolen bicycle detection system 200 is often used in a place where a plurality of bicycles are parked side by side. The operator searches for the IC tag G attached to the seat tube of the bicycle to be inspected with the grip 3 of the detection device 1. Then, the detection unit 205 is pressed against the part where the IC tag G is stretched. Since the cushioning member 212 is provided on the surface of the detection unit 205, no contact sound is produced even when it is applied to the seat tube T, and the detection unit 205 and the bicycle frame are not damaged.

  When the detection unit 205 approaches the IC tag G, the built-in FRID reader 222 reads the crime prevention registration number information of the IC tag G (step 1). The detection device 1 determines whether or not the crime prevention registration number has been read correctly (step 2). If it cannot be recognized correctly, an error is displayed on the display unit (step 3). Further, a warning sound such as a buzzer is generated along with the error display using a warning sound generating device such as a speaker (not shown).

  Next, the identification number provision part 23 provides an identification number with respect to the acquired crime prevention registration number information (step 4). For example, as shown in FIG. 15, the identification number “001” is assigned to the security registration number information “J2494763”, the identification number “002” is assigned to the security registration number information “J5837349”, and the security registration number information “J10940475” is assigned. ID number “003” is assigned. The reason for assigning an identification number to each crime prevention registration number information is as described above. The registration number information given the identification number is stored in the storage unit of the detection device 1 (step 5).

  Subsequently, it is determined whether or not the crime prevention registration number for the next bicycle is acquired (step 6). Specifically, when the information of the next IC tag G is acquired by the detection unit 205, the process is automatically continued (return to step 1). On the other hand, when ending, the end button 37 is pushed. Thereby, the crime prevention registration number information memorize | stored in the memory | storage part 24 is transmitted to the portable terminal 2 (step 7). The portable terminal 2 receives the crime prevention registration number information and displays it on the display unit 25 (step 8). Moreover, in the portable terminal 2, position information is acquired by the GPS function, and the position information is given to all the crime prevention registration number information received (step 9). For example, as shown in FIG. 15, the information of “Kamiyama 3-chome, Higashihiroshima-shi, Hiroshima” is assigned to all crime prevention registration number information as position information.

  Next, the collation part 30 of the portable terminal 2 connects to the police system 32 (step 10), and transmits the stored crime prevention registration number information (step 11). The subsequent processing is the same as the processing shown in the flowchart shown in FIG.

  As described above, according to the stolen bicycle detection system 200, the crime prevention registration number can be easily and accurately read by the RFID and collated with the police system 32, so that the stolen bicycle can be easily determined. In addition, the detection device 201 can be used easily without the operator bending down or taking an unreasonable posture because the detection unit 205 can move freely, can be extended and contracted to adjust its length, and can be bent freely. it can.

  In addition, you may provide the cushion material 212 over not only the front and back of the detection part 5, but the whole surface. Alternatively, the surface of the cushion material 212 may be subjected to water repellent treatment, or a material having a water repellent function may be used for the exterior of the cushion material 212. The detection unit 205 may be fixed with respect to the rod 4 at a certain angle (for example, 45 degrees or more and 90 degrees or less). In that case, the rotating shaft 206 is unnecessary. Further, the flexible tube 8 can be omitted.

(Embodiment 3)
FIG. 17 is an explanatory diagram showing the operation of the stolen bicycle discovery system according to the third embodiment of the present invention. 18 and 19 are flowcharts showing the operation of the stolen bicycle discovery system. Hereinafter, differences from the first embodiment will be mainly described. This stolen bicycle detection system is characterized in that it performs a process when the security seal indicating the security registration number is peeled off from the bicycle. In the stolen bicycle detection system of the first and second embodiments, the portable terminal 2 is provided with input means such as a numeric keypad and additional information giving means for giving additional information to the inputted body number (not shown). . The database 35 of the police system 32 stores vehicle number information together with the crime prevention registration number.

When the crime prevention seal of the bicycle that is left is peeled off, the worker reads the vehicle body number stamped on the bicycle frame and inputs the vehicle body number from the input means of the portable terminal (step 31). . At the time of input on the portable terminal, additional information indicating that the vehicle body number is input is added to the head of the number information (step 32). For example, “xxxx” is automatically input as additional information. An identification number is given by the identification number giving unit 23 to the vehicle body number information to which this additional information is inputted (step 7). Hereinafter, Step 8 to Step 14 are the same as those in the first embodiment.

  Next, in the police system, the server 34 sorts the transmitted crime prevention registration number information and vehicle body number information based on the additional information (step 33), and if the vehicle body number information is included, the database 34 The vehicle number information stored in 35 is collated (step 34).
