  Next, components and functions of the travel detection unit 202 will be described with reference to FIG. FIG. 3 is a system configuration diagram of the travel detection unit 202 according to the first embodiment, in which the travel detection unit 202 installed on the rear wheel portion of the bicycle is surrounded by a broken line.

  The travel detection unit 202 converts the self-standing mechanism unit 303 fixed to the axle 302 to float the wheel 301 from the ground and parks the setting state of the self-standing mechanism unit 303 so that it can be easily processed in the subsequent stage. It comprises means 304, travel determination means 306 for determining whether or not the vehicle 100 is in a parked state, and transmission means 305 for transmitting information of the conversion means 304 to the travel means 306.

  The self-supporting mechanism unit 303 is fixed to the axle 302 and can be operated by a person using the vehicle 100 with a foot or the like. When the vehicle 100 is parked, the self-supporting mechanism unit 303 is moved below the wheel. Moreover, when running the vehicle 100, the self-supporting mechanism means 303 can be moved to the rear part. In the example of FIG. 3, the self-supporting mechanism means 303 is a method of floating the wheel 301 to be self-supporting. However, the self-supporting mechanism means may not be positioned at the axle 302. For example, it may be installed around the travel determination means 306 of the vehicle 100 (a central position of the vehicle 100).

  The conversion unit 304 is for converting the mechanical movement of the self-supporting mechanism unit 303 into a change amount that is convenient when the travel detection unit 306 processes the movement. For example, the conversion means 304 is a conversion mechanism that converts the movement of the self-supporting mechanism means 303 into a horizontal linear movement in the case of a movement that draws an arc when the vehicle 100 is parked and when the vehicle 100 is run. The conversion means 304 is a mechanism for converting the mechanism motion into an electrical signal so that a predetermined switch is turned on when the self-supporting mechanism means 303 transitions to the parking state.

  The transmission unit 305 is for transmitting the state of the self-supporting mechanism unit 303 from the conversion unit 304 to the travel determination unit 306. If the information converted by the conversion unit 304 is a momentum in the horizontal direction, the transmission unit 305 is made of metal or the like. It is made up of wires and plates. Further, if the converted information is an electrical signal, it is composed of a harness for transmitting the signal.

  The travel detection unit 306 determines whether or not the vehicle 100 is parked according to the state of the conversion unit 304. In the case of physical kinetic energy in which information converted by the conversion means 304 is transmitted by a wire or the like, the information is configured by a mechanism that drives a switch in accordance with the kinetic energy. If this switch is parked, the wire is pulled and the switch is turned off. Further, when the signal is converted into an electric signal by the conversion means 304, a level conversion circuit, a rectifier circuit, and the like are used to remove an appropriate voltage level and noise from the control means 204 in the vehicle management unit 110 shown in FIG. Then, the signal shaping is performed by a filter circuit or the like, and it is determined whether or not the vehicle 100 is parked.

  Next, the control flow of the vehicle management unit 110 is shown in FIG. 4, and the control flow of the information terminal 120 is shown in FIG. First, the flow until the vehicle management unit 110 transmits the information stored in the storage unit 301 in response to the information request message from the information terminal 120 will be described with reference to FIG.

  First, the traveling detection means 202 of the vehicle management unit 110 determines whether or not the vehicle 100 is in a traveling state (S401). If it is determined that the vehicle 100 is not running, the control unit 204 activates the transmission / reception unit 203 in accordance with a predetermined protocol or setting and performs carrier sense (S402).

  When the signal from the information terminal 120 is detected by the carrier sense in S402, the control unit 204 shifts the transmission / reception unit 203 to the reception state and demodulates the information request message transmitted from the information terminal 120 (S403).

  Whether or not the information request message received and demodulated in S403 is consistent with a predetermined message format, whether the information requested in the information request message is vehicle information or owner information, etc. The requested content is confirmed by the control means 204 (S404).

  When the control unit 204 determines in S404 that the message format is consistent with the predetermined message format, the information requested by the information request message transmitted from the information terminal 120 among the information stored in the storage unit 201. Only read out (S405).

  The information read from the storage unit 201 is incorporated into a response message according to a predetermined protocol in the control unit 204 (S406). Next, the control unit 204 activates the transmission / reception unit 203 in accordance with a predetermined protocol, and transmits the response message generated in step S406 (S407). After the transmission in S407, the process proceeds to step S401.

  In S401, when the vehicle 100 is traveling, the state is periodically checked, and it is not possible to make a transition to another step unless the state where the vehicle 100 is not traveling can be confirmed. If there is no signal from the information terminal 120 when carrier sense is performed in S402, the process proceeds to S401.

  In addition, if the information request message received in S404 is not consistent with a predetermined message format, or if it is not permitted to disclose the requested content, the information request message cannot be handled. The included response message is generated by the control unit 204 in accordance with a predetermined message format (S408). In order to transmit the response message generated in S408 in accordance with a predetermined protocol, the control unit 204 activates the transmission / reception unit 203 to perform transmission (S409).

  With the above contents, the vehicle management unit 110 returns vehicle information and owner information requested from the information terminal 120 according to the traveling state of the vehicle 100. In the process of S402 to S407, the vehicle detecting unit 202 If it is detected that 100 is traveling, the processing can be interrupted.

  Next, a control flow in which the information terminal 120 requests and acquires vehicle information and owner information from the vehicle management unit 110 will be described with reference to FIG. First, it is detected that an input operation for requesting vehicle information or owner information of the vehicle 100 is performed from the operation unit 253 of the information terminal 120. (S501). In S501, as long as there is no operation, it will be in the state of waiting for an operation input.

  If the operation of the operation unit 253 is detected in S501, the terminal control unit 252 determines information requested to the vehicle management unit 110 according to the information input from the operation unit 253, and generates an information request message. (S502).

  Next, in order to transmit the information request message generated in S502 in accordance with a predetermined protocol, the protocol information stored in the terminal storage unit 254 is read, and the terminal transmission / reception unit 251 is activated according to the information. (S503).

  Subsequently, carrier sense is performed before transmitting the information request message from the terminal transmission / reception means 251, and it is confirmed whether or not another device is communicating (S504). If there is a carrier, stay in this step for a while. If the carrier cannot be confirmed in S504, an information request message is transmitted from the terminal transmitting / receiving unit 251 (S505), and the operation of the terminal transmitting / receiving unit 251 is stopped (S506).

  After a predetermined time has elapsed from the step of S506, the terminal transmission / reception means 251 is activated (S507), and carrier sense is performed (S508). In S508, it is confirmed whether there is a response message for the information request message from the vehicle management unit 110. If there is no carrier, the process returns to S506.

  When the carrier is detected in S508, the terminal transmission / reception means 251 including the demodulation circuit is activated (S509), and the demodulation operation is started (S510). The terminal transmitting / receiving unit 251 performs a demodulation operation, and the terminal control unit 254 determines whether the demodulated response message conforms to a predetermined message format and matches the content requested by the information request message transmitted in S505. (S511).

  If it is determined in S511 that they match, the operation of the terminal transmission / reception unit 251 is stopped (S512), and the vehicle information and owner information of the vehicle 100 included in the received response message are stored in the terminal storage unit 254. The information is stored (S513), and the information is displayed on the display means 255 (S514).

  If the response message demodulated in S511 does not match the predetermined message format or does not contain the requested information, the terminal control means is not a response message transmitted from the vehicle management unit 110. The determination is made at 254, and the process proceeds to S506.

  According to the above processing, since the information of the vehicle management unit 110 mounted on the vehicle 100 can be read into the information terminal 120 according to the state of the vehicle 100, the vehicle parked in the parking prohibited area is also referred to as the traveling vehicle. The owner information can be efficiently and easily acquired by classification. In addition, it is possible to grasp a vehicle parked in a parking lot and apply it to a billing system according to the use situation.

(Embodiment 2)
FIG. 6 is an internal configuration diagram of the vehicle management unit and the information terminal in the second embodiment. The description of the configuration in FIG. 6 that is the same as the internal configuration in FIG. 2 shown in the first embodiment is omitted, and the other components are described.

  6 differs from FIG. 2 in that the time management means 205 is provided in the vehicle management unit 110, the travel detection means 202 determines whether or not the vehicle 100 is traveling, and the duration is determined by the time management means 205. The control means 204 determines whether the vehicle has been left for a predetermined time using the clock output from the control unit 204. The time management means 205 includes a crystal oscillator, a ceramic oscillator, an oscillation circuit composed of a capacitor and a resistor, an element such as a temperature-corrected TCXO, or a system that receives radio waves from the outside and performs accurate time management. Is done.

  Since the configuration of the travel detection means 202 is different in the second embodiment, the following description will be given.

  The travel detection means 202 will be described with reference to the system diagram of the travel detection means 202 shown in FIG. The travel detection unit 202 is configured by components surrounded by a broken line in FIG. 7, and includes a reference sensor 702 attached to a spoke 701 constituting the wheel 301, a reception sensor 704 attached to a fork 703, and a reception sensor 704. It comprises speed detecting means 706 for calculating angular velocity or traveling speed based on information, and wired communication means 705 for connecting the detecting sensor 704 and speed detecting means 706.

  The reference sensor 702 attached to the spoke 701 is made of a magnetic material such as a magnet. The reception sensor 704 is fixed to the fork 703 of the vehicle 100 and is configured by a coil or a reed switch.

  At the same time as the wheel 301 rotates, the reference sensor 702 also rotates and passes by the side of the reception sensor 704. At this time, when the reception sensor 704 is formed of a coil, the magnetic field changes when the reference sensor 702 passes in the vicinity of the reception sensor 704, so that an electromotive force is generated in the coil in the reception sensor 704. This electromotive force is sent to the speed detection means 706 via the wired communication means 705. The speed detection means 706 converts the level of the electromotive force generated by the reception sensor 704 to generate a pulse and converts it into a traveling speed in consideration of the angular speed or the diameter of the wheel 301.

  Further, when the reception sensor 704 is constituted by a reed switch, the wheel 301 rotates, and the switch is turned on when the reference sensor 702 passes near the reception sensor 704, and the wire communication means 704 is used. The speed detection means 706 calculates the angular speed or traveling speed by counting the number of times the switch in the receiving sensor 704 is turned ON / OFF, and determines whether the vehicle 100 is stopped or traveling.

  As described above, whether the vehicle 100 is parked by the control unit 204 based on the information determined by the speed detection unit 706 in the travel detection unit 202 and the information of the time management unit 205, including the duration of the state. Make a decision.

  Next, a control flow when the vehicle management unit 110 described above requests vehicle information, owner information, and the like of the vehicle 100 from the information terminal 120 will be described with reference to FIG.

First, the traveling detection means 202 in the vehicle management unit 110 detects the angular velocity, and the control means 204 determines whether the vehicle 100 is traveling (S801). Here, the acceleration is detected by the travel detection means 202, and if the control means 204 is greater than a reference value determined in advance, it is determined that the vehicle 100 is traveling. If it is determined that the vehicle 100 is not traveling, the control unit 204 does not proceed to the next step, and continues to determine traveling from the angular velocity detected by the traveling detection unit 202 periodically.

  In step S801, when the angular velocity is equal to or less than a predetermined reference value, the control unit 204 determines that the vehicle 100 is not traveling, acquires a clock from the time management unit 205, and is in a state where the vehicle 100 is not traveling. The duration time is calculated (S802).

  If this duration is less than a predetermined period (here, 2 hours), the process returns to step S801, and if it is more than that, the process proceeds to the next step (S803). Next, as a preparation for receiving the information request message transmitted from the information terminal 120, the transmission / reception means 203 is activated.

  Subsequently, the control means 204 performs control so that the transmission / reception means 203 in the vehicle management unit 110 performs carrier sense at a predetermined time (S804), and it is determined that the carrier is equal to or greater than a predetermined reference value. In this case, it is determined that the information request message has been transmitted from the information terminal 120, and the transmission / reception means 203 is completely activated to start reception (S805), and when the value is below the reference value, the operation of the transmission / reception means 203 is stopped. After controlling by the control means 204, the process proceeds to S801 (S812).

  The information received and demodulated in S805 is collated with the predetermined message format (S806), and if there is a match, the vehicle stored in the storage means 201 according to the content of the information request message 100 vehicle information and owner information are read out (S807). The read information is embedded in a predetermined message format in the control means 204 to generate a response message (S808).

  Subsequently, in order to transmit the generated response message in accordance with a predetermined protocol, the transmission information is read from the storage unit 201, the transmission / reception unit 203 is activated and carrier sense is performed (S809). If carrier sense is not performed, a response message is transmitted from the transmission / reception means 203 (S810). After the transmission is completed, control is performed from the control unit 204 to stop the operation of the transmission / reception unit 203 (S811), and the process proceeds to step S801.

  On the other hand, when the message received by the transmission / reception means 203 in S806 does not match the predetermined format, or when trying to read the information restricted in the access stored in the storage means 201 The control unit 204 generates an error message (S813), activates the transmission / reception unit 203 to perform carrier sense, and transmits an error message after confirming that there is no carrier (S814).

  According to the above process, since the information of the parking unit 110 mounted on the vehicle 100 can be read into the information terminal 120 according to the state of the vehicle 100 and the time during which the state is continued, It is possible to efficiently and easily acquire information by separating only the vehicles that have been stolen and thrown away after a predetermined period. In addition, when a vehicle sales and maintenance company performs repairs and maintenance, the vehicle information can be grasped instantaneously, and it can be used to provide customers with high-quality services.

(Embodiment 3)
FIG. 9 shows an internal configuration diagram of the vehicle management unit 110 and the information terminal 120 in the third embodiment. In the configuration of FIG. 9, the description of the same components as those in FIGS. 2 and 6 will be omitted, and the other components will be described below.

  9 differs from FIG. 2 and FIG. 6 in that the information terminal 120 has terminal time management means 256 and the configuration of the travel detection means 202 in FIG.

  First, the terminal time management unit 256 in the information terminal 120 will be described. The terminal time management unit 256 determines a time to wait for a response message transmitted from the vehicle management unit 110. When an information request message is transmitted from the information terminal 120 to a plurality of vehicles, each vehicle management unit 110 performs carrier sense and transmits requested information when other vehicle management units are not transmitting.

  At this time, the information terminal 120 sequentially receives response messages transmitted from a plurality of vehicle management units, but it is necessary to determine whether response messages have been transmitted from all the vehicle management units. For this reason, the information terminal 120 performs carrier sense by the terminal transmission / reception means 251 and counts a predetermined time by the terminal time management means 256, and during that time, if no carrier is detected, the information terminal 120 receives all the vehicle management units 110 from the vehicle. It is determined that the response message has been received.

  Next, the travel detection means 202 will be described with reference to FIG. FIG. 10 is a system diagram of the travel detection unit 202 according to the third embodiment. The travel detection unit 202 includes components surrounded by a broken line. The travel detection unit 202 includes a locking unit 1001 for locking the wheel 301 and a locking confirmation unit 1002 for detecting that the wheel 301 is locked by the locking unit 1001.

  The locking means 1001 has a ring-shaped configuration and is a mechanism in which the user manually moves the bar to perform locking. The locking confirmation means 1002 is configured to convert mechanical operation into an electric signal so that the switch is turned on when the locking means 1001 is in the locked state, and the vehicle 100 is running with the switch turned on. Judge that there is no.

  Here, it is determined whether or not the vehicle 100 is traveling by the locking confirmation means 1002, but in addition to this, it is possible to monitor the power generation voltage and pulse width of the power generation device attached to the vehicle, and the seat where the user sits. It is also possible to detect and judge the pressure and the operation state of the operation part of the vehicle.

  Then, the control flow at the time of the information terminal 120 in Embodiment 3 transmitting an information request message to the vehicle management unit 110 and receiving a response message is shown in FIG.

  First, the terminal control unit 252 detects whether an input operation for requesting vehicle information or owner information has been performed by the operation unit 253 (S1101). At this time, the operation performed by the person from the operation means 253 is not for acquiring vehicle information of a specific vehicle but for inputting a request for acquiring vehicle information to a vehicle existing in a certain area. Therefore, the vehicle-specific ID or the like is not input.

  Subsequently, when an input operation is detected from the operation unit 253, an information request message is generated by the terminal control unit 252 in accordance with the input information (S1102), and the terminal control unit is configured to activate the terminal transmission / reception unit 251. Control is performed from 252 (S1103), and then carrier sense is performed (S1104).

If a carrier can be detected in S1104, wait for a while, wait for a while, and perform carrier sense again. On the other hand, if the carrier cannot be detected in S1104, the terminal control means 252 transmits an information request message according to a predetermined protocol to the terminal transmission / reception means 251 (S1105), and the terminal transmission / reception means 251 operates after the transmission is completed. Control is performed from the terminal control means 252 to stop (S1106).

  Next, the terminal transmission / reception means 251 is activated again from the terminal control means 252 (S1107), carrier sense is performed (S1108), and if a carrier is detected, it is determined that a response message is transmitted from the vehicle management unit. Then, the terminal transmission / reception means 251 starts a reception operation (S1109), and then performs a demodulation operation (S1110).

  If the message demodulated in S1110 is configured in a predetermined message format and includes the vehicle information or owner information requested by the information request message transmitted in step S1105 (S1111), and if they match, The received information is stored in the terminal storage means 254 (S1112). Subsequently, the process proceeds to step S1106 in order to receive a response message transmitted from another vehicle.

  On the other hand, if the received signal level obtained by performing carrier sense in the terminal transmission / reception unit 251 in S1108 is less than or equal to a predetermined value, the terminal time management unit 256 continuously reduces the carrier sense to the predetermined value or less. Count the number of times. For example, if the counted result is less than 10 times, the process proceeds to step 1106. If the counted result is 10 times, the information request message is transmitted from the information terminal 120, and the vehicle is in a condition that the response message can be transmitted. It is determined that all have been transmitted (S1113). Then, the vehicle information, owner information, etc. memorize | stored in the terminal memory | storage means 254 are displayed on the display means 255 (S1114).

  In S1111, if the data transmitted, received, and demodulated from the vehicle management unit 110 does not match the information requested in advance, the terminal control means 252 accumulates the number of times of mismatch in step S1111, and counts it. It is determined whether or not the predetermined number of times has been reached (here, less than 3 times) (S1115).

  If it is determined in S1115 that the cumulative value of the number of mismatches has not reached the predetermined number, the process proceeds to step S1106. If it is determined in S1115 that the cumulative value of the number of mismatches has reached less than a predetermined number, the terminal control means 252 generates an error message that the received information is different from the requested information, and displays it. Displayed by means 256 (S1116).

  The information of the vehicle management unit 110 mounted on a plurality of vehicles can be efficiently and easily collected using the information terminal 120 by the above processing. By using the obtained information, it is possible to efficiently acquire and manage information on multiple vehicles parked in parking prohibited areas and information on stolen vehicles, as well as when vehicle manufacturers and sales companies perform maintenance It can be used as an effective information collection means. In addition, when operating the information terminal 120, personal information can be stored in the storage means in more detail by first authenticating the user with a password or the like, and the situation when the vehicle has an accident It can be used as evidence or traceability.

  As described above, the vehicle management unit attached to the vehicle proposed in the present invention detects whether or not the vehicle traveling information is detected and outputs the stored vehicle information or owner information in response to a request from the information terminal. Because it is possible to collect information only on vehicles that are parked reliably, it is possible to easily collect information on vehicles that are left unattended, and also to help collect information for vehicle maintenance. be able to.
