Description

  The present invention relates to a bicycle management system that can cope with vehicle theft of a bicycle using a self-powered RFID tag.

  As a measure against bicycle theft, an RFID tag is attached to the bicycle body, an RFID reader / writer is installed at a key point in the city such as a gate at the entrance of a bicycle parking lot, and a transmission signal is received. This system identifies the bicycle that transmitted the signal based on the unique identification number for each bicycle included in the transmission signal from the RFID tag, and if it is a stolen bicycle, the bicycle owner or police station For example, information indicating that a stolen bicycle has been found is transmitted to a predetermined target. By this method, the location of the stolen bicycle or the thief himself / herself is identified without being noticed by the thief of the bicycle, and the system aims to collect the stolen bicycle or clear the thief.

  Patent Document 1 is an example of a bicycle management system using such an RFID tag. FIG. 3 shows a configuration example of a conventional bicycle management system in Patent Document 1. In Patent Document 1, an RFID tag is screwed into a screw hole provided in a bicycle frame, embedded in a recess provided in the frame, or a sheet-like RFID tag is attached to the frame so that the thief of the bicycle can It is configured so that the tag cannot be easily removed.

  In FIG. 3, an RFID tag 32 is attached to the frame of the bicycle 31, and when the bicycle 31 passes near the RFID reader / writer 35 installed in the city, a signal including a unique identification number transmitted by the RFID tag 32 is transmitted. Is received by the RFID reader / writer 35 and the received content is transmitted to the communication network 39. The RFID reader / writer 35 can be installed in a plurality of places such as an RFID tag mounting store 36 and a manufacturer 37 of the bicycle 31. Alternatively, a signal from the RFID tag 32 may be received by the portable RFID reader 33 and the received content may be transmitted to the communication network 39 via the wireless base station 34. Information read from the RFID tag 32 is collected in the registration information center 41 via the communication network 39. The RFID tag attachment store 36 is a facility having a function of actually attaching the RFID tag 32 to the bicycle 31 and transmitting the registration information including the unique identification number of the bicycle to the registration information center 41.

  The registration information center 41 has inquiry means 42 and notification means 43, inquires the database server 40 for the unique identification number of the RFID tag 32, and investigates whether the bicycle 31 having this unique identification number has been notified of theft. To do. As a result, if it is found that there is a problem such as the bicycle 31 being notified of theft, the police station 38 is notified via the communication network 39 that the bicycle 31 has been found. The discovery information can be communicated to the owner of the bicycle 31 via. It is also possible to notify the facility in the vicinity of the RFID reader / writer 35 that has received the signal including the unique identification number to prompt the discovery of the bicycle 31 and the restraint of the thief.

  On the other hand, there is an example described in Patent Document 2 as an alarm system for preventing theft of a bicycle that does not use an RFID tag. This alarm system does not manage the bicycle using RFID tags, but detects the abnormality when the bicycle is stolen, operates the installed buzzer to inform the thief of the bicycle to the surroundings, and informs the thief Is intended to give up the continuation of criminal acts. Therefore, it is not intended to identify the location of the stolen bicycle or the thief himself without being noticed by the thief and to collect the stolen bicycle or to approve the thief. FIG. 4 shows a configuration example of a conventional bicycle alarm system described in Patent Document 2. 4A is a diagram showing an outline of a bicycle equipped with an alarm system for theft prevention, and FIG. 4B is an enlarged view of the hub dynamo 45 portion of FIG. 4A. It is.

  In FIG. 4A, the bicycle 44 includes a hub dynamo 45 and a first key device 46. Here, the hub dynamo is a power generator built into the axle of the front (or hub) of the front or rear wheel of a bicycle, and it lights up compared to a rim dynamo that generates power by contacting the rotor against the belly of a bicycle tire. Sometimes it has a small effect on pedal weight. The important point is that, in general, the rider cannot manually switch between the operation and non-operation of the apparatus, and is always in an operating state when the bicycle is running. FIG. 4B is an enlarged view showing the configuration of the hub dynamo portion, and shows the case where the hub dynamo is viewed from the side of the bicycle. In FIG. 4B, the axle 47 is fixed to the bicycle main body, and the wheel case 51 and the drum 48 surrounding the bicycle rotate together with the wheels as the bicycle travels. The drum 48 is provided with holes for attaching spokes constituting the wheels. The wheel case 51 incorporates a piezoelectric buzzer 50 and a second key device 49, and when the bicycle is stolen, the piezoelectric buzzer 50 operates to generate a loud warning sound.

  In Patent Document 2, a first key device is a lock for locking a bicycle, and a vibration sensor (not shown) is incorporated therein. Here, an electric circuit is formed between the hub dynamo, the internal piezoelectric buzzer, and the first key device. When the key is removed from the first key device, that is, in the key lock state, the electric circuit is formed. The circuit is configured to be a closed circuit. Therefore, if the vibration is detected by the vibration sensor in the key lock state, or the hub dynamo is activated and the bicycle is confirmed to travel, the piezoelectric buzzer will operate and a loud warning sound will be emitted. Become. Here, even when the first key device is destroyed, the electric circuit remains a closed circuit. In order to make the electric circuit open and to deactivate the piezoelectric buzzer, the first key device You must insert the correct key. Therefore, since a thief who does not have the correct key does not have a means for preventing the operation of the piezoelectric buzzer, the piezoelectric buzzer continues to operate forever, and the bicycle can be prevented from being stolen.

  The second key device provided in the hub dynamo stops the operation of the piezoelectric buzzer by inserting the key into the hub dynamo. If the bicycle owner accidentally operates the piezoelectric buzzer, This is for stopping the operation. Since this second key device cannot stop the piezoelectric buzzer unless the correct key is inserted, even if a thief who does not have the correct key notices the presence of the second key device, the piezoelectric buzzer can be operated using this. It is impossible to stop. Therefore, it does not cause a security vulnerability in this alarm system.

JP 2003-306186 A Japanese Patent Laid-Open No. 11-134563

  The conventional bicycle management system using the RFID tag described in Patent Document 1 has the following two problems. The first problem is to secure a drive power source for the RFID tag to be attached to the bicycle. In general, in a management system using an RFID tag, there is a case where a power source is not mounted on the RFID tag side, a carrier wave of an inquiry signal from the RFID reader / writer is received, and power is extracted from this signal to be used as a drive power source. Many. However, in this case, it is necessary to bring the RFID reader / writer and the RFID tag close enough, and in general, the owner of the RFID tag cooperates such as consciously bringing the article incorporating the RFID tag close to the antenna of the RFID reader / writer. It is assumed that it will be obtained.

  However, in the bicycle management system, since the rider of the bicycle when detecting the RFID tag is a thief of the bicycle, naturally, such cooperation cannot be obtained, and the RFID tag is attached to the antenna of the RFID reader / writer. It is difficult to get close to. On the contrary, since it is necessary to conceal the existence of the RFID tag from such a rider, the antenna provided in the RFID tag cannot be made so large, and the mounting position is not easily noticed by the rider. There may be cases where it is not suitable. For this reason, it is desirable that the RFID tag side has its own drive power supply. However, in the case of a system with a built-in battery, there is a problem with battery life, so driving that does not require maintenance such as battery replacement. A power supply was required.

  The second problem is prevention of diffusion of personal information of a legitimate user of the bicycle. In the system described in Patent Document 1, when an inquiry signal is received from a plurality of RFID reader / writers or portable RFID readers installed in the city, a unique identification number is unconditionally assigned from the RFID tag mounted on the bicycle. A response signal including is transmitted. For this reason, even if the bicycle has not been stolen, information on the position and time of the bicycle is sent to the registration information center together with the unique identification number, and is inquired of the database server. Therefore, it is theoretically possible for a third party who is accessing the communication network to obtain such information and know in real time when and where the user on the bicycle is. Since this situation significantly impairs the reliability of the bicycle management system, when the RFID reader / writer reads information that includes the bicycle's unique identification number, the bicycle should only encounter problems such as theft. A limited system is required.

  The first and second problems are as follows. The hub dynamo included in the bicycle is used as a driving power source for the operation of the RFID tag, and a key lock (hereinafter referred to as a security key) is applied to the RFID tag system. Both can be solved by the solution means.

  Unlike the rim dynamo, the hub dynamo provided in the bicycle is always in an operating state while the bicycle is running, and the rider cannot switch between the operation and non-operation in principle. Therefore, by obtaining the operating power of the RFID tag from the hub dynamo, it is possible to always keep the operating state while the bicycle is running without performing maintenance such as battery replacement. Therefore, when the bicycle is stolen, sufficient power is supplied to the operation of the RFID tag by driving the hub dynamo, so that a response signal with sufficient strength can always be reliably transmitted to the RFID reader / writer.

  On the other hand, by using the security key, when the bicycle owner inserts the key into the key device, the RFID tag can be kept inactive so that no response signal is transmitted. By this method, the RFID reader / writer installed in the city receives a response signal from a bicycle that has passed through and acquires its unique identification number when the key device is not inserted or the key device is destroyed. This is limited to cases where the bicycle is experiencing problems such as theft. Therefore, it is possible to prevent the information on the position and time of the owner of the bicycle at the normal time from leaking onto the communication network.

  The power supply method using the hub dynamo used in the first solution and the use of the security key are described in Patent Document 2. However, the bicycle alarm system described in Patent Document 2 does not use an RFID tag, and does not monitor the location of a stolen bicycle using a communication network.

  By the way, in the case of the first solution, when the thief does not insert the key into the bicycle key device or drives the hub dynamo with the key device destroyed, the RFID tag installed is The response signal is continuously transmitted, and when the bicycle passes near the RFID reader / writer installed in the city, this signal is received, and the information of the unique identification number flows along with the time and position of the stolen vehicle on the communication network. It will be.

  In general, it is very difficult to receive a response signal transmitted by an RFID tag mounted on a bicycle, analyze the signal, and read the bicycle's unique identification number and other information, and the thief succeeds in such an operation. It is hard to think. However, if only a signal is transmitted from the bicycle, there is a risk of detection using a receiving device capable of receiving the frequency band used in such a management system. If the thief knows that the bike is being monitored by the system, or the bike may be immune from theft, it will eventually target another bike to prevent crime It doesn't matter. Furthermore, when a thief detects the transmission of a signal, it may be possible to destroy the RFID tag or antenna attached to the bicycle and disable monitoring by this system.

  Therefore, as a third problem, it is not easy for the thief to know whether or not the bicycle is monitored by the bicycle management system, and it is difficult for the thief to remove or destroy the RFID tag or the antenna. A bicycle management system was required.

  This third problem can be solved by the following second solving means. In other words, even when a hub dynamo and a security key are used, and the hub dynamo is driven when the key is not inserted into the key device or when the key device is destroyed, the RFID tag mounted on the bicycle alone will not respond. No signal is transmitted, and a response signal is transmitted only when an inquiry signal is received from an external RFID reader / writer in the above case. Since a receiving device that can be easily obtained by a thief cannot transmit a correct inquiry signal to the bicycle, the RFID tag does not transmit a response signal. It is very difficult for a thief to obtain and operate an RFID reader / writer capable of transmitting such an inquiry signal, and by implementing this second solution, the reliability of the bicycle management system can be improved. . Further, if the inquiry signal from the RFID reader / writer is encrypted and a response signal is not transmitted when the RFID tag cannot be decrypted, the reliability of the bicycle management system is further improved.

  That is, the present invention is a bicycle management system that manages a key device to which a security key is attached, a hub dynamo, and a bicycle having an RFID tag using an RFID reader / writer, and the RFID tag is obtained by the hub dynamo. The RFID tag is configured to operate when the security key is not attached to the key device, or when the key device is damaged. In the bicycle management system, a unique identification signal is transmitted during operation, and the RFID reader / writer receives the unique identification signal transmitted from the RFID tag.

  Further, the present invention is the bicycle management system, wherein the RFID tag transmits the unique identification signal only when receiving an inquiry signal from the RFID reader / writer.

  Furthermore, the present invention is the bicycle management system characterized in that the inquiry signal from the RFID reader / writer is encrypted.

  In the present invention, the RFID reader / writer is connected to a communication network, and the communication server is connected to a center server in which bicycle information of each registered bicycle and a unique identification signal of each bicycle are recorded. When the RFID reader / writer receives the unique identification signal transmitted from the RFID tag, the RFID reader / writer receives the received unique identification signal, receiver position information of the RFID reader / writer, and reception time information on the center. The center server inquires bicycle information of each registered bicycle based on the received unique identification signal, and receives the RFID reader / writer receiver position information, reception time information, and the inquiry. Bicycle management characterized by contacting bicycle information obtained by It is a stem.

  Furthermore, the present invention is a bicycle management system that performs bicycle stolen vehicle management using the unique identification signal of each bicycle received by the RFID reader / writer.

  According to the solution of the present invention, in the bicycle management system using the RFID tag, the operation power of the RFID tag mounted on the bicycle is obtained from the hub dynamo included in the bicycle, and the security key is used together. Is configured so that the RFID tag operates only when the key device is not attached to the predetermined key device or when the key device is damaged. As a result, a drive power source for the RFID tag can be secured, so that a response signal can be transmitted to the RFID reader / writer with sufficient strength, and maintenance such as battery replacement is not required. Furthermore, by limiting the operation of the RFID tag only when the hub dynamo is driven and the key device is not operating normally, a response signal from the RFID tag is transmitted to the RFID reader / writer when a legitimate user is traveling It is constituted so that it is not done. Accordingly, it is possible to prevent the legitimate user's personal information including information on the unique identification number of the bicycle from leaking onto the communication network via the RFID reader / writer.

  Further, according to the different solution of the present invention, in the bicycle management system, when the hub dynamo is driven as described above and the security key is not attached to a predetermined key device, or the key device is damaged. Even if it exists, it is assumed that the RFID tag does not transmit a response signal. In the above case, the RFID tag mounted on the bicycle is configured to transmit a response signal only when an inquiry signal is received from an external RFID reader / writer. This makes it more difficult for a thief of a bicycle to detect the presence or absence of an RFID tag using a receiving device or the like, and the position of the bicycle including the unique identification number of the bicycle at the time of theft without being noticed by the thief. Enable to monitor time information on the communication network. Further, if the inquiry signal from the RFID reader / writer is encrypted and the response signal is not returned unless it can be decrypted on the RFID tag side, the reliability of the bicycle management system can be further improved.

  Hereinafter, an embodiment of the bicycle management system of the present invention will be described with reference to FIGS. 1 and 2. Among these, FIG. 1 is a figure which shows the example of a structure of the bicycle management system in this invention.

  In FIG. 1, a hub dynamo 13 is installed on a front wheel or a rear wheel of a bicycle 11, and a key device 14 is provided on a frame. The key device 14 has a role as a lock for locking the bicycle wheel to prevent theft during parking, and the wheel lock is released by attaching the security key 15 to the key hole. On the other hand, the RFID tag 12 is attached to the bicycle 11 at a position where it cannot be directly seen from the outside, and the antenna 11 is configured to allow non-contact two-way communication with the RFID reader / writer 18 installed in the city. Has been. The hub dynamo 13 provides operating power to the RFID tag 12 when the bicycle 11 is running, and an electric circuit is provided between the key device 14 and the RFID tag 12 and the security key 15 is not attached. Alternatively, the circuit is closed when the key device 14 is damaged, and the RFID tag 12 is configured to operate.

  First, the case of the bicycle management system based on the first solution of the present invention will be described. In this case, when the bicycle rider forcibly runs the bicycle 11 without attaching the security key 15 to the key device 14, the electric circuit including the key device 14 becomes a closed circuit and the hub dynamo 13 Since the operating power is supplied to the tag 12, the RFID tag 12 transmits a radio signal including its own unique identification number to the surroundings. If the bicycle 11 is a legitimate owner, the bicycle 11 cannot be run without attaching the security key 15 to the key device 14, so the bicycle 11 has been stolen, and the rider is the bicycle 11. None of the thieves. In this state, when the bicycle 11 passes near any one of the RFID reader / writers 18 installed in the city, the RFID reader / writer 18 receives a signal including a unique identification number transmitted by the RFID tag 12 and transmits it to the communication network 19. The read received content is transmitted.

  The RFID reader / writer 18 is installed at a plurality of locations in the city such as a monitoring system 16 and a bicycle parking lot 17 provided at important points. The RFID reader / writer 18 receives a signal including a unique identification number of the read bicycle and the reception time of the signal. Information on the position of the RFID reader / writer 18 is added, and the information is sent to the communication network 19. The center server 20 needs to be determined in advance based on these three types of information: a bicycle unique identification number, receiver position information of the RFID reader / writer 18 that has read the signal, and reception time information. Implement appropriate measures. That is, the fact of the theft is notified to the owner of the bicycle 11 who has been stolen, arrangement information regarding the stolen bicycle is sent to a place where the thief is likely to stop, such as a bicycle parking lot, or the police station Measures such as notification will be taken.

  On the other hand, in the case of the bicycle management system based on the second solving means of the present invention, even if the bicycle rider runs the bicycle 11 without the security key 15, a radio signal is transmitted from the RFID tag 12 by itself. There is nothing. However, when the bicycle 11 passes in the vicinity of the RFID reader / writer 18 installed in the town, the inquiry signal from the RFID reader / writer 18 is received, and the RFID tag 12 transmits a response signal including a unique identification number to the surroundings. It becomes. When the RFID reader / writer 18 receives this response signal, the received content is transmitted to the communication network 19 together with the receiver position information and the reception time information at this time. The center server 20 receives the series of information and performs predetermined necessary measures.

  Since the operation power is always supplied from the hub dynamo 13 to the RFID tag 12 when the bicycle 11 is traveling, the RFID tag 12 relies on the carrier wave of the received signal which is an inquiry signal from the RFID reader / writer 18. There is no need. Therefore, even if the intensity of the received signal is weak, the RFID tag 12 amplifies it by itself, analyzes it with sufficient sensitivity, and sends a necessary response signal including its own unique identification number to the RFID reader / writer 18. Can be sent to. In this case, as described above, since a response signal is transmitted only when an appropriate inquiry signal is received from the external RFID reader / writer 18, the thief of the bicycle 11 simply uses the receiving device or the like to use the RFID tag 12 Even if it tries to receive a signal from the RFID tag 12, it cannot receive a signal from the RFID tag 12. Therefore, it is difficult for the thief to detect whether the RFID tag 12 is mounted on the bicycle 11 and the mounting position thereof. If the inquiry signal from the RFID reader / writer 18 at this time is encrypted, the reliability of the bicycle management system is further improved.

  FIG. 2 is a diagram showing an example of the mounting position of the RFID tag on the bicycle in FIG. In FIG. 2, a key device 22 for attaching a security key to the rear wheel of the bicycle 21 and a hub dynamo 23 are installed on the front wheel. An RFID tag including an antenna is not easily detected by a thief of a bicycle, and performs wireless communication in one or two directions with an RFID reader / writer. It is necessary to mount it at a position where it is as small as possible. Since the main members of the bicycle are generally made of metal other than the tire, such as a frame, a tire rim, and a spoke, the RFID tag should be installed as far as possible from these members. The following four locations shown in FIG. 2 are suitable as installation locations for RFID tags that satisfy this condition.

  The first installation location is the back side of the seat surface of the saddle 24 included in the bicycle 21 or the inside of the saddle 24. The saddle 24 is generally made of a non-metal, and it is advantageous for communication that it is installed at a relatively high position among the components of the bicycle. Moreover, since the surface area is large and it has a sufficient area for placing the antenna of the RFID tag, the RFID tag can be installed so as not to touch the thief's eyes at all. In addition, it is necessary to provide wiring from the RFID tag to the key device 22 and the hub dynamo 23. By providing this wiring inside a metal frame that exists immediately below the saddle 24, it is possible to arrange the wiring so as to be inconspicuous. is there.

  The second installation place is the lower side of the light 25 included in the bicycle 21 or the inside of the light 25. In many cases, the light 25 is made of a member having a metallic luster, but actually, a resin that has been subjected to vapor deposition is often used instead of a metal. Compared to other members made of metal, the RFID tag The installation conditions are excellent. Although the surface area is not necessarily large, it is installed at a relatively high position among the components of the bicycle, which is advantageous for wireless communication. Of course, a wiring for supplying power to the light 25 is provided between the light 25 and the hub dynamo 23. By using this wiring also for the wiring with the RFID tag, the thief is completely uncomfortable. It is possible to make an electrical connection without connecting.

  The third installation location is the upper part of the rear wheel upper part of the rear wheel of the bicycle 21 or the inside of the reflector 26 installed on the rear frame. In general, the reflector 26 is often made of a resin, and is usually installed in a vertical direction, and thus is often arranged somewhat away from a metal mudguard. For this reason, if the RFID tag is placed inside the reflector 26, the RFID tag can be placed sufficiently away from the metal member, which is convenient for communication with the RFID reader / writer. The surface area is not necessarily large, and the installation position is not necessarily high among the components of the bicycle, but it is never too low, and the problem of installation height is that it protrudes from the metal member. Can be supplemented. Further, the wiring between the hub dynamo 23 and the hub dynamo 23 can be arranged so as to be relatively inconspicuous, for example, by providing it on the back side of the mudguard placed nearby.

  The fourth installation place is inside the grip 27 of the handle of the bicycle 21. In general, the grip 27 is made of a non-metal such as rubber, but a metal handle is provided directly below the grip 27, and it cannot be said that the installation conditions of the RFID tag are excellent in that respect. However, it is possible to increase the non-metallic region when installing the RFID tag inside by thinning the bicycle handle only in the region where the grip 27 is provided. Since the grip 27 is installed at the highest position among the components of the bicycle, the communication environment with the RFID reader / writer is the best, and since there are two grips 27 on the left and right, two RFID tags are provided, A configuration in which an RFID tag with a better communication condition is always used is possible. Although the surface area is not necessarily large, since the grip 27 is cylindrical, the antenna area can be increased by configuring the RFID tag antenna in a cylindrical shape. Further, since there is a handle frame directly under the grip, it is possible to provide wiring to the hub dynamo 23 via this inside.

  In addition to this, for example, the inside of a tire is also conceivable as an installation place of the RFID tag. However, in this case, intense vibration is always applied to the RFID tag while the bicycle is running, and the relative position of the RFID tag in the bicycle always changes. Furthermore, the installation conditions are considerably inferior to the installation locations of the four RFID tags, such as the installation of wiring to the hub dynamo 23 is not easy.

  As described above, based on the embodiment of the present invention, an RFID tag that can transmit a response signal of sufficient strength to an RFID reader / writer and that does not require maintenance such as battery replacement is provided. The used bicycle management system can be realized. Further, in this bicycle management system, it is possible to prevent leakage of personal information of a legitimate user including information on the unique identification number of the bicycle to the communication network. Further, the above description is for explaining the effect in the case of the embodiment of the present invention, and thereby limits the invention described in the scope of claims or reduces the scope of claims. is not. Moreover, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.
